Description

TECHNICAL FIELD

[0001] The present application belongs to the field of civil aviation, and particularly relates to a civil aviation airport ground operation scheduling control system. BACKGROUND

[0002] With the vigorous development of the civil aviation industry, the scale of airports continues to expand, the number of takeoff and landing of flights increases day by day, and the passenger throughput continues to rise, which makes the complexity of airport ground operation increase exponentially, and puts forward more stringent requirements for the operation scheduling control system.

[0003] The civil aviation airport ground operation scheduling control is a new mode system taking the existing core production system "flight operation command system" as the carrier to improve the efficiency of flight support operation of ground service companies, improve the level of operation management, and realize vertical, precise and efficient control of flight support tasks. The innovative business model changes the management architecture, so as to realize the intensive and intelligent control of flight status, task information and support nodes involved in flight support, and realize the "one machine, one group and one management" (one aircraft, one business information group and one full-time controller) flat operation control mode for single flight support process.

[0004] The traditional civil aviation airport ground operation control system faces several core problems:

[0005] Flight resource scheduling: mainly relies on manual experience and relatively simple rules to allocate flight time, arrange parking spaces and allocate ground support resources. For example, in the allocation of flight time, it mainly depends on historical data and rough traffic flow estimation, and lacks comprehensive consideration of real-time traffic flow, weather changes, aircraft performance differences and other dynamic factors, which easily leads to unreasonable distribution of flight time, serious congestion in peak period and idle resources in low period.

[0006] Personnel and vehicle scheduling management: the current system has obvious deficiencies. For example, the ground staff scheduling usually adopts fixed shift system or simple shift mode, without fully considering the skills and expertise of employees, work load balance, rest needs and flight dynamic changes. This results in overwork of some employees and under-task of some employees, and in the face of flight delay, cancellation and other unexpected situations, it is difficult to make reasonable personnel allocation decisions quickly. For ground vehicle scheduling, it mostly relies on manual instructions, and frequent empty driving and long waiting time phenomenon occurs, which not only wastes fuel resources, but also reduces the overall support efficiency.

[0007] Communication and information exchange: Traditional systems have the problem of information silos, and information between different departments and different links is difficult to share in real time and smoothly. For example, between the tower and the ground support department, there is a delay in the update and transmission of flight information, which leads to the ground staff's inability to grasp important information such as the actual arrival time of the flight and the change of the parking position, and the inability to make corresponding preparations in advance. The information communication between the ground support links, such as passenger service, luggage loading and unloading, aircraft refueling, cleaning and maintenance, is not smooth, and often due to the fact that the information of the previous link has not been timely transmitted to the subsequent link, causing work connection failure and delaying the progress of flight support.

[0008] Multi-department collaboration: Flight support involves a long chain, multiple departments (more than 10), multiple positions (more than 20), and multiple control nodes (more than 30). Each department needs to work closely and highly collaboratively to successfully complete the support.

[0009] Operating costs: Ground services rely on a large number of front-line personnel and need to meet the requirements of "all-weather, high-intensity, and high-compliance". Labor costs are often the main expenditure item. The scale of front-line personnel is large, and ground services involve check-in, luggage handling, passenger guidance, passenger elevator / car bridge operation, aircraft cleaning, cargo loading and unloading, etc. positions, 24-hour shifts (covering the entire flight departure and landing period), and single-airport front-line personnel can reach several thousand. The high salary and welfare expenditure, the high labor intensity of front-line positions (such as luggage handling is heavy physical labor), and the complex working environment (open-air operation, noise pollution, etc.) require higher wages to attract labor; in addition, the welfare costs of social security, public accumulation fund, night shift subsidy, high-temperature / low-temperature subsidy, etc. further increase the expenditure. Training and qualification costs, ground personnel need to go through strict civil aviation safety training (such as the "Civil Aviation Safety Protection Regulations"), equipment operation certification (such as special vehicle driving), and need to be retrained regularly, with significant training costs and time costs. Seasonal fluctuation costs, temporary workers need to be temporarily recruited or overtime pay needs to be paid during peak seasons (such as holidays and summer), and personnel are idle during off-seasons, increasing the pressure of fixed salary allocation. Moreover, in response to unexpected events, the response mechanism of the traditional system is not flexible and efficient. Once faced with adverse weather, equipment failure, safety incidents, and other unexpected situations, the system cannot quickly generate a comprehensive and scientific emergency response plan, and the collaborative response capability between departments is poor, making it difficult to integrate resources and adjust operation plans in a short period of time, resulting in large-scale flight delays and causing serious negative impacts on passenger travel and airport operations.

[0010] In recent years, although some advanced technologies have been introduced by some airports to improve the ground operation control system, such as the use of some simple information management tools and the introduction of basic flight information display systems, the overall operation effect has not fundamentally solved the above-mentioned complex problems, and the intelligence, integration, and collaboration level of the system needs to be greatly improved.

[0073] A civil aviation airport ground operation scheduling control system for implementing the civil aviation airport ground operation scheduling control method, the system comprises:

[0074] The basic data acquisition module: when the user successfully logs in the system, the module will automatically trigger the acquisition operation of the basic data, and the acquired basic data includes role information, organizational structure, member list, attention list, general group and flight group.

[0075] The above-mentioned data obtained will be automatically stored in the local micro database. In order to improve the data processing efficiency, the system does not update the data every time; the server will only update the part of the data which has changed when it monitors that the data has been updated.

[0076] The synchronization flight data module: after the basic data is synchronized, the module will continue to trigger the acquisition operation of the corresponding data according to the flight group information, and the acquired data includes guarantee information and flight information.

[0077] Among them, the guarantee information contains guarantee node information; the flight information covers the basic information of the inbound and outbound flights, specifically including the planned, expected and actual landing time, the planned, expected and actual take-off time, the parking space, the aircraft number, the boarding gate, the flight attribute, the flight state, the flight segment, etc.

[0078] The unread message synchronization module: every time the user logs in the system, the module will automatically trigger the synchronization operation of the unread message.

[0079] The synchronized unread messages include personal messages, common group messages, and flight group messages, and specifically include the number of unread messages, @ reminders for the user, and the like.

[0080] Flight list sorting module: after the data synchronization is completed, when the user enters the main window, this module displays two tab pages on the left side of the main window, namely, "all" and "controlled flight".

[0081] The "all" tab page contains personal conversations, common group conversations, and flight conversations; the "controlled flight" tab page contains only flight conversations.

[0082] In terms of sorting rules, the conversations in the "all" tab page are sorted according to the rule of new messages on top, that is, the conversation with the latest message is placed at the top; the conversations in the "controlled flight" tab page are sorted according to the flight dynamics, specifically, sorted according to the order of landing and takeoff.

[0083] Guarantee node and guarantee message synchronization module: guarantee node, when the user selects the flight he guarantees and enters the guarantee window (i.e., the right part of the main window), this module triggers the related functions. This window contains the message module, the guarantee module, the member list, the flight dynamic module, the guarantee information module, and the cargo and mail line module.

[0084] The key node information of the flight guarantee is displayed on the top of the window, and the node will change according to the type of the flight, such as single arrival flight, single departure flight, continuous flight, domestic flight, international flight, cargo flight, and passenger flight, and the displayed nodes are different.

[0085] The main nodes include wheel chock, cargo compartment door opening, passenger compartment door opening, cleaning end, aircraft release, boarding release, passenger boarding, passenger arrival, stowage completion, passenger compartment door closing, cargo compartment door closing, wheel chock removal, and pushing out. In addition, for the epidemic, international passenger and cargo disinfection process nodes are added, such as disinfection start, cabin sealing, disinfection end, and secondary disinfection.

[0086] Each node will use different colors and shapes to remind the user according to different initial and reported states:

[0087] a. Blue hollow: node to be reported

[0088] b. Green solid: normally reported node

[0089] c. Orange solid: delayed reporting node

[0090] d. Red hollow: node with timeout unreported

[0091] e. Gray hollow: node without reporting

[0092] And each node will prompt the expected reporting time and the actual reporting time. When the mouse hovers over the node, detailed execution information will be displayed.

[0093] The operation and control post has the function of manually reporting nodes. Right-clicking the node will pop up a manual reporting node time window. After selecting the time, the reporting can be completed.

[0094] Guarantee message, in the control flight window right side is equipped with "guarantee information" tab, guarantee information covers member action information, guarantee execution information, flight dynamic information, and is respectively distinguished using different icons, which includes all execution and change information.

[0095] Flight dynamic module: users can click the "flight dynamic" function button in the upper right corner to open the flight dynamic detail page. The flight details displayed on this page include:

[0096] a. Basic information of the flight, including flight number, flight date, parking space, aircraft number, aircraft model, and route;

[0097] b. Arrival flight information (if any), including flight status, flight nature, international / domestic attribute, planned landing time, expected landing time, actual landing time, and loading port;

[0098] c. Departure flight information (if any), including flight status, flight nature, international / domestic attribute, planned takeoff time, expected takeoff time, actual takeoff time, and boarding gate.

[0099] When there is flight dynamic change information, the corresponding attribute will change dynamically.

[0100] Member status module: the "member" tab is provided on the right side of the control flight window. After the user clicks this tab, the group member list will be displayed. Member information includes the member's avatar, name, department, and post name.

[0101] The member list will display the user's online status in real time. Users with green dots indicate that they are online, and users with gray dots indicate that they are not currently online.

[0102] For on-site support personnel, the member list will display their support status, including acceptance, arrival, start, and end, to clearly indicate the personnel's on-duty status.

[0103] Cargo line data synchronization module: each control flight will obtain the corresponding cargo line information according to the flight type. This information includes unloading and loading manifest information.

[0104] The user can view relevant information in the following manner: clicking the "flight status" function button in the upper right corner, opening the flight status details page, and clicking the load sheet tab in the independent window. If there is issued load sheet information, this place will display detailed loading information, including version number, total weight of cargo and mail, sheet maker, sheet making time, notes, and manifest details (covering positions, destinations, types, and total amounts, etc.).

[0105] For the unload sheet information, if there is issued unload sheet information, the details of the unload sheet will be displayed, including the number of bags, the number of arriving passengers, the sheet making time, and the manifest information (covering positions, destinations, types, and weights, etc.).

[0106] System announcement module: When the operation control personnel releases an announcement, the user enters the control flight, and the new announcement will automatically pop up in the form of a pop-up window, so that the user can view it in a timely manner.

[0107] If the user is an operation control personnel, he or she can perform announcement editing and publishing operations. Click the "publish announcement" button at the lower right of the announcement window on the "member" tab page to open the publish announcement window. After editing the announcement content, click the "publish" button to complete the announcement publishing.

[0108] Role group and cross-group message module: The role group is a special function of the system, and its design purpose is to enable personnel who need to concentrate their efforts to not receive invalid information. This function is realized by relying on the cross-group message mechanism.

[0109] Specifically, the members of each role group can send messages to the current any control flight; the personnel of each control flight can also send messages to one or more role groups. For example, the configuration center can inquire about the loading situation and passenger information of the current flight through this mechanism.

[0110] Post font module: The background can set the font and color of each functional department, and after the setting is completed, the relevant information will be synchronized to the front end.

[0111] Therefore, the font and color of the text message sent by each post are in the preset state. This setting facilitates the quick differentiation of messages belonging to different functional departments, thereby better ensuring flight operation.

[0112] Normal message sending and receiving module: Based on the IM system, this module supports sending various types of messages between security members, including text, voice, pictures, and documents, etc.

[0113] After the user edits the message, he or she can use the @ function to remind the specified personnel, or perform cross-group reminders.

[0114] At the same time, the user can receive messages sent by other members in real time, and the received messages will be automatically displayed in the conversation list and conversation window.

[0115] Split and merge module of message window: each conversation (including personal conversation, general group conversation, flight conversation) can be presented in the form of a separate window.

[0116] The user double-clicks a conversation in the conversation list, and the conversation pops up separately, and its constituent elements are exactly the same as the main window.

[0117] Through this function, the user can view multiple control flights at the same time in order to perform simultaneous security operations.

[0118] Member attention and unattended module: the user can click the "organization" menu of the function menu on the left side of the main window to switch to the organization page.

[0119] The page contains 3 tab pages, namely organization, attention and group. The user can click a user or click anywhere that can click the user's avatar to view the user's information.

[0120] In the user page, the user can click the "attention" or "unattended" button, so as to facilitate subsequent quick search for the user and achieve the purpose of single-line communication.

[0121] Flight task assignment module: after the user enters the system, the user clicks the "flight task assignment" button below the main page to open the task assignment page.

[0122] After opening the assignment page, the system background will automatically obtain the list of types of work, the list of terminals, the list of teams and the member information; at the same time, the background will continue to obtain the unassigned tasks and the assigned tasks of the flight, and display these tasks in the form of time axis in the lower area of the page.

[0123] In the filtering condition, the user can select different dates to query the corresponding date of the flight, so as to facilitate the advance of flight task assignment.

[0124] The user drags a certain unassigned flight to a certain person by clicking it with the mouse, thereby completing the task assignment action, at which time the background will automatically add the corresponding person to the control flight. In addition, the lower part of the assignment page is provided with a filtering condition for the user to quickly find the flight.

[0125] The beneficial effects achieved by the present application are:

[0126] Control level: the control level is simplified from 4 layers to a single layer;

[0127] Target information acquisition time: information transmission is more efficient, and the target information acquisition time is shortened from an average of 60 seconds to 2 seconds;

[0128] Information communication mode: information communication is changed from serial and step-by-step transmission to point-to-point direct communication;

[0129] Running control continuity: running control is upgraded from segmented to full-process supervision, and the efficiency of operation command is improved by 80%.

[0130] System and business integration: multiple system integration automatically processes information, replacing the original independent and manual processing mode; one person with multiple capabilities and one post with multiple responsibilities in business, breaking the relatively independent and responsible state, and reducing the operation error rate by 60%.

[0150] In the present embodiment

[0151] S1. The file system is based on the Aliyun OSS system, and the file interface is redeveloped:

[0152] The present application is aimed at the special needs of file management in the aviation ground service scene (multi-service cooperation, high safety requirements, efficiency first), based on the Aliyun OSS system for customized development, breaking through the limitations of the general file system. Breakthrough in format compatibility, reconstruct file parsing and adaptation logic, support aviation ground service whole process file type (such as maintenance manual PDF, flight command recording MP3, aircraft appearance inspection JPG, etc.), solve the problem of business fragmentation caused by the "format barrier" of traditional system; Security system reconstruction, establish a three-level file security mechanism, access permission, according to post (check-in / flight attendant / cargo), role (administrator / operator), business scene (daily / emergency) to divide file access permission, realize the "thousand people thousand face" file visible range; Encrypted storage, using AES-256 encryption algorithm to encrypt the file content, superimposed SSL encryption in the transmission process, to ensure the file "storage-transmission" whole link security; Anti-theft chain protection, through Referer check, Token dynamic authorization, intercept illegal domain name / IP file call, avoid the aviation ground service core file (such as flight support scheme) being maliciously acquired; Efficiency optimization design, integrated intelligent file processing module, automatically identify file type and business demand (such as preview scene automatically compress picture to 200KB, storage scene keep original precision), balance "transmission efficiency" and "data integrity".

[0153] Business side benefits, full-process file collaboration efficiency is improved, the file format and system barrier of each link (check-in, maintenance, catering, freight) of ground service is broken, and "one interface, full-scene penetration" is realized. Taking flight support instruction transmission as an example, the PDF scheme, MP3 scheduling instruction and JPG position map uploaded by the command center can be identified and accurately called by each post terminal in seconds, the file interaction time is compressed from the original average of 10 minutes to 1 minute, supporting the efficient mode of "2-second target information acquisition" of operation command; aviation-level data security guarantee, the file storage system conforming to the civil aviation data security specification (such as "Provisions on the Management of Civil Aviation Information Security") is constructed, permission control makes "passenger information files only visible to check-in post, and maintenance records only editable by authorized personnel", and the file leakage risk is reduced by 95%; encryption and anti-theft chain double protection resist external attacks (such as hacker theft of flight support files) and internal misoperation, guaranteeing "zero leakage and zero tampering" of more than 40,000 flight file interactions, and assisting in "80% reduction in 10,000 unsafe errors"; the actual landing of cost reduction and efficiency increase, storage cost optimization, intelligent compression function makes the file size reduced by 40%-60% on average, reduces the occupation of Aliyun OSS storage, and saves 20%-30% of annual storage cost; terminal response acceleration, small-size files are loaded faster in weak network environment of remote positions (such as corridor bridges and remote positions), the waiting time of ground service personnel for calling maintenance manual and luggage information is shortened from 3 minutes to 10 seconds, which directly improves the on-site support efficiency and supports "80% improvement of operation command efficiency".

[0154] Patent scheme collaborative value, the file system innovation is not isolated, but is deeply cooperated with the overall scheme of ground service, provides a unified file interaction standard for "multi-system fusion" (each business system transmits files through a new interface), promotes "manual processing" to "automatic flow", and builds a file security boundary for "business integration (one person with multiple functions)" (the permission is automatically adapted when multiple personnel operate files, and overreach is avoided); in cooperation with "whole-process supervision", the file operation leaves traces and can be checked (such as who calls which file and modifies which content), and becomes an important technical support for "zeroing" of operation errors.

[0155] Briefly, the file system interface is reconstructed, the pain points of "file management difficulty, high security risk and low interaction efficiency" of aviation ground service are solved, the overall efficiency of ground service is promoted from the bottom layer technology, the "single-point innovation-system efficiency improvement-business value-added" chain value is realized, and the key technical foundation for intelligent transformation of aviation ground service is provided.

[0156] S2. The instant messaging (IM) system is based on the message transmission protocol of the publish / subscribe mode of the service end architecture according to the MQ and MQTT architecture:

[0157] Lightweight and efficient message transmission base, aiming at the needs of aviation ground service multi-terminal, high concurrency, weak network compatibility, the invention discards the traditional IM architecture bloated problem, and constructs the service end based on MQ (message queue) + MQTT (lightweight publish / subscribe protocol); The protocol level advantage is landed, the characteristics of "light, open and simple" of MQTT are used to adapt to the complex environment of ground service (such as corridor bridge, remote machine position weak network scene), the message package can be as small as 2 bytes, so that the ground terminal (mobile phone / PDA / industrial computer) can still stably receive and send instructions under 2G network, and the pain point of traditional IM "network difference message block" is solved; Load independent design, decoupling message production and consumption through publish / subscribe mode, whether the ground scene is "single machine group instruction" or "full machine position broadcast", the system automatically adapts to the load, ensures that the message is not lost and delayed during the support of 10,000 times of support, and supports "operation command efficiency improvement of 80%".

[0158] Ground scene message interaction closed loop, around the aviation ground service "cooperative command, safety guarantee, whole process response" demand, design special IM function; Precise message reach, support single subscription (such as maintenance A receiving aircraft maintenance instruction), broadcast subscription (such as all ground crew receiving flight delay notification), special subscription (such as check-in post receiving VIP passenger information), replace traditional "group chat screen, instruction flood" mode, let ground personnel 100% accurate receive task instruction, directly promote "operation error rate reduction of 60%" (reduce instruction misreading / omission); All types of message support, covering all types of information carriers in ground service, text (command instruction), voice (real-time communication), picture (aircraft damage evidence), file (meal list), video (operation specification teaching), realize "one IM system carries all business information", replace the original multi-tool (intercom + email + U disk) scattered transmission, message transmission efficiency is improved by 70% (such as maintenance site taking fault picture, 1 second synchronization command center); Localization and intelligent interaction, integrate message local storage (still can view historical instruction in offline), intelligent reminder (timeout task pop-up window + voice alarm), positioning (real-time display of ground personnel / equipment position), push (emergency instruction strong reminder), build "offline available, timeout warning, location visible" ground cooperative network, take "positioning function" as an example, the command center can dispatch the nearest ground personnel to handle the emergency task within 10 seconds, help "operation control continuity from segmented to whole process supervision".

[0159] The dual breakthrough of ground service efficiency and safety, the qualitative leap of command efficiency, from the traditional mode of "walkie-talkie shouting a layer, telephone asking a layer", to the intelligent cooperation of "instruction second sending, state second returning", the delay of message receiving and sending is compressed from the original average of 3 minutes to 1 second (the advantage of low delay of MQTT protocol); Multi-type message + accurate reach, let the ground service response speed increase by 80%, directly support "more than 40,000 times of guarantee error zero"; Safety and compliance landing, message local storage + encrypted transmission (combined with S1 file system encryption), guarantee the safety of ground service sensitive information (such as passenger identity, flight security plan) "storage-transmission", the risk of message leakage is reduced by 90%; Operation trace (who sent and received which instruction, when to process) becomes an important trace basis for "80% reduction in unsafe errors for 10,000 times", which meets the requirements of civil aviation "traceable and supervised"; Cost and experience optimization, replace walkie-talkie (need frequency coordination), email (slow and weak interaction) and other traditional tools, annual communication cost is saved by 50% (reduce hardware procurement + traffic cost); Intelligent reminders, positioning and other functions make ground service personnel operation more "relaxed", indirectly promote "customer satisfaction improvement by 60%" (fast response, less errors).

[0160] The nerve center of ground service intelligence, the IM system is not isolated, but deeply cooperates with the overall ground service plan, provides a real-time message channel for "target information 2-second acquisition" (command instruction, guarantee data second-level flow), cooperates with "file system (S1)", realizes "message-file" integrated interaction (such as directly accessing encrypted files in IM), supports "multi-post fusion (one person with multiple functions)", and makes ground service personnel receive all business line messages and call all system resources through an IM terminal, become the nerve center of "business fusion + system fusion", highlighting the systematic innovation value of the invention.

[0161] In short, the present application reconstructs the architecture and function of the ground service IM system, creates a "light, accurate, full-scene, high-security" message cooperation network, solves the pain points of "slow communication, chaotic instruction, weak safety" of aviation ground service, and supports the overall efficiency upgrade of ground service from the bottom (command efficiency + 80%, error rate -60% / 80%), provides a "nerve-level" interaction base for aviation ground service intelligent operation, and has significant technical uniqueness and business irreplaceability.

[0162] S3. http network communication implementation:

[0163] The application is a communication base suitable for adapting to the complex environment of ground service, aiming at the characteristics of multi-terminal heterogeneity, large network fluctuation and high security level of aviation ground service, breaking through the limitation of traditional HTTP communication which has strong universality but weak scene adaptation, and building a customized communication system; Scene data packet protocol design, abandoning the redundant fields of general HTTP data packet, designing ground service business exclusive packaging protocol, automatically adapting fields according to data types (such as command instruction, equipment state, passenger information) (such as instruction containing "flight number + priority + execution post", equipment state packet "terminal ID + fault code + timestamp"), reducing the data packet size by 30%-50%, adapting to weak network environment (such as remote machine position, unstable signal on the bridge), ensuring "light and accurate" data transmission; Standardized encapsulation of full-link interface, unified encapsulation of communication interface of file transmission (S1), instant messaging (S2) and business system (such as check-in system, maintenance dispatch), forming an interactive standard of "one interface specification, full system compatibility". For example, the message packet of the IM system, the encrypted file packet of the file system and the instruction packet of the business system are all transmitted through the same HTTP interface, solving the problem of "multi-system interface fragmentation and high adaptation cost" in traditional ground service, reducing the cost of cross-system development and maintenance; High-reliability connection and reconnection mechanism, aiming at the network interruption problem caused by the frequent movement of ground service terminals (such as maintenance PDA, baggage truck industrial computer), designing intelligent connection management module, real-time monitoring network state (signal strength, delay), automatically downgrading transmission in weak network (such as sending instruction text first, delaying large file transmission); After network interruption, trigger "gradual reconnection" (3 times of rapid retry within 10 seconds, 5 minutes of periodic retry after failure + local cache pending data), ensuring that the data is not lost after network interruption, and automatically resuming transmission after network recovery (such as maintenance records recorded by maintenance personnel in remote machine position when the network is interrupted, which are synchronized to the command center within 10 seconds after network recovery).

[0164] The dual protection of security and cooperation, fine-grained permissions and multi-terminal management and control system, login permission limitation, based on ground staff (check-in, maintenance, cargo), terminal type (fixed counter / mobile PDA), business scenario (daily / emergency), design "account-post-terminal-operation" four-dimensional permission matrix. For example, the cargo account can only log in through the cargo terminal, and can only call the "luggage data upload" interface, to prevent cross-posting and unauthorized operations (such as non-command post calling flight support instruction interface); multi-terminal identification and cooperation, through terminal unique identification (such as device MAC + SIM card ID) to realize "the same account multi-terminal login state visualization" (command center can real-time view "account A is logged in at the same time in the check-in counter + PDA") and support "data synchronization + operation mutual exclusion" (such as PDA modified instructions, counter end real-time update, to avoid repeated operation); cross-terminal module encapsulation and cooperation, the communication module of the command center server, ground terminal (PC / mobile / PDA), peripheral system (such as the corridor control system, luggage conveyor) is standardized encapsulation, so that different hardware (x86 architecture computer, ARM architecture PDA, embedded industrial computer) can interact through a unified interface. For example, the "flight stop at the corridor bridge instruction" issued by the command center can be received and executed by the corridor control system (embedded) and the ground staff PDA (mobile terminal) at the same time, realizing the cooperation of "system-device-person".

[0165] Support ground service whole process efficient and safe operation, multi-terminal collaborative efficiency quality improvement, solve ground service "terminal miscellaneous, interface disorder, data out of sync" pain points, make the data interaction of command center, check-in, maintenance, cargo and other multi-terminal delay from the original average 30 seconds to 5 seconds. Taking flight support as an example, the command center pushes passenger information to the check-in counter (fixed terminal) through HTTP interface, maintenance PDA (mobile terminal) and baggage system (industrial control terminal), multi-terminal data "real-time synchronization, no deviation", support "operation command efficiency improvement 80%" efficient mode; Communication reliability guarantee in weak network scene, for ground service high frequency weak network scene (such as remote machine, parking apron), through lightweight data packet, intelligent reconnection mechanism, the data transmission success rate is improved from 70% to 99.9%. For example, in heavy rain, the maintenance staff takes pictures of the aircraft skin damage with PDA at the remote machine, although the network fluctuates, but through "transmit thumbnail first + cache original picture when network is disconnected + resume transmission when network is restored", the command center can get the key information within 1 minute, avoiding the delay caused by communication interruption; Safety compliance and risk prevention and control are strengthened, four-dimensional permission matrix makes the non-authorized access interception rate reach 100%, and the illegal behaviors such as "cargo operation passenger information, temporary worker call core instruction" are eliminated, which meets the control requirements of "civil aviation safety information management regulation" on data access; Multi-terminal identification and operation leave traces (such as "account A modifies support instruction on PDA terminal at 10:05"), which provide "full link evidence" for operation error traceability, and help "reduce 80% of unsafe errors in 10,000 flights" and "reduce operation command errors to zero".

[0166] System maintenance and cost optimization, unified interface packaging reduces the cost of ground service terminal access by 60% (no need to develop interface repeatedly); Lightweight data packet and intelligent reconnection mechanism reduce network bandwidth occupation, annual traffic cost is saved by 20%-30%, and terminal hardware power consumption is reduced (such as PDA endurance is prolonged by 1-2 hours).

[0167] The "vascular system" of ground service intelligentization, the HTTP network communication is not an independent module, but a "blood vessel" of the whole ground service system, supporting the efficient cooperation of core modules, providing a safe transmission channel (encrypted data packet + permission verification) for file system (S1), ensuring the security of encrypted file "storage-transmission" in the whole link; Provide stable message carrier for IM system (S2) (reconnection mechanism ensures that messages are not lost, multi-terminal identification supports cross-terminal message synchronization), support "2 second target information acquisition" and "accurate message subscription"; As a "multi-system integration, business integration" bottom link, it enables each link (people, equipment, system) of ground service to realize "real-time data flow" and "accurate instruction reach" through unified communication standard, highlighting the systematic innovation and irreplaceability of the invention.

[0168] In short, the application creates a "light, reliable, safe and compatible" ground communication base through customized HTTP communication architecture and function design, which not only solves the pain points of aviation ground "multi-terminal cooperation difficulty, poor network communication, and loose safety control", but also supports the leap of overall operation efficiency (command efficiency + 80%) and safety level (error rate - 60% / 80%) from the bottom, provides "vascular level" basic support for aviation ground intelligent operation, and has significant technical innovation and business landing value.

[0169] S4. Realize local micro database:

[0170] Adapt to the lightweight data management base of multi-terminal, the application breaks through the limitation of traditional centralized database relying on strong network, and constructs a localized micro database system, aiming at the heterogeneous (PC / mobile PDA / industrial computer) of aviation ground terminal, multi-language demand (Chinese / English / Japanese, etc.), and unstable network characteristics. Multi-terminal and multi-language interface packaging, design cross-terminal and multi-language adaptation layer, for different client (such as C# for Windows counter terminal, Java / Objective-C for mobile PDA, and C++ for industrial computer), package unified localized database interface (add, delete, modify and query), and support multi-language version (such as Chinese terminal calling "query flight" interface, English terminal calling "Query Flight" interface, and unified underlying logic), solve the problem of high cost of ground multi-terminal development and adaptation; Intelligent data collaboration mechanism, two-way synchronization strategy, local database and cloud core library linkage through "incremental synchronization + conflict checking" mechanism (such as luggage information recorded by ground personnel offline at remote machine, only synchronize new / modified part after network recovery, avoid full transmission; If the same data is modified by multiple people, automatically merge according to "time stamp + priority of authority"); Hierarchical cache design, local cache for high-frequency access basic data (such as flight schedule, machine position information, and post permission table), cache validity period dynamically adapts to business scenarios (such as temporary flight information cache for 4 hours, and fixed machine position information cache for 7 days); Data structure change self-adaptation, when the cloud data structure is upgraded (such as adding "luggage trace code" field), local library automatically compatible with old structure through "version number checking + field mapping", no need to upgrade terminal forcibly, smooth processing, avoid business interruption caused by structure change.

[0171] The "offline available, online seamless" experience of the ground terminal, the business continuity guarantee in the weak network / offline scenario, the high frequency of the aviation ground crew facing the weak network / disconnected network environment such as remote site, corridor bridge, and apron, the local micro database solves the core pain points through "local cache + offline operation"; when the ground crew uses the PDA to perform tasks (such as aircraft maintenance, luggage checking), the flight data (such as aircraft type, passenger capacity) cached locally can be directly queried, and the work records (such as "1# engine check normal") are entered, and the operation response speed is compressed from the average 3 seconds depending on the cloud to 0.5 seconds; the operation data (such as luggage damage record) during the network interruption is automatically stored locally, and the incremental synchronization is completed within 10 seconds after the network is restored, ensuring that "offline does not delay work, and network restoration does not lose data", supporting the continuity of "full-process supervision" of flight support (even if the network is interrupted, the key operation can still be traced); the problem of repeated loading of basic data is completely solved, in the traditional mode, the ground terminal needs to load basic data from the cloud every time it starts or switches pages (such as the check-in counter refreshing the flight list every hour, and each loading takes 20 seconds), resulting in waste of bandwidth and delay in response. The local micro database uses the "one-time loading, local reuse" mechanism; the basic data is cached when logging in for the first time, and the local database is directly called for subsequent operations, and the loading time is reduced from 20 seconds to 1 second; only when the cloud data is updated (such as flight delay changes), the local cache is updated through incremental synchronization, reducing the basic data transmission volume by more than 90%, reducing the load pressure of HTTP network communication (S3), and avoiding terminal lag caused by repeated loading (such as the operation smoothness of the check-in counter during peak hours is improved by 60%); the efficiency of multi-language and multi-terminal cooperation is improved, the multi-language interface adapts to the international aviation hub scenario (such as Beijing and Shanghai Pudong Airport), foreign ground crew (such as maintenance and cargo positions) can call the local library interface through their mother tongue (English, Japanese, etc.), and the operation efficiency is improved by 40% (reducing language understanding errors); multi-terminal data cooperation (such as passenger information entered by the fixed counter is visible within 10 seconds through the local library of the mobile PDA), supporting the business integration mode of "one person with multiple functions and one post with multiple responsibilities" (such as when the check-in personnel temporarily assist in guiding passengers, they can quickly query the boarding gate information of the flight cached locally through the PDA); data security and consistency are guaranteed, local data is stored in encrypted form (in conjunction with the encryption mechanism of the S1 file system), preventing information leakage caused by terminal loss (such as passenger ID number and flight security information); during synchronization, the data is transmitted through the HTTP encrypted channel of S3, and combined with "data signature + permission verification", the local and cloud data are consistent (such as the security instructions modified by the ground crew are consistent with the data of the command center after synchronization), helping to reduce the operation error rate by 60%.

[0172] The "last mile" support of the ground service data flow, the local micro database is not an independent module, but a deep cooperation with the whole ground system, becoming the "terminal nerve" of data flow; in linkage with the IM system (S2), the local storage of IM messages relies on the micro database, ensuring that historical command instructions (such as "repeated flight landing instructions") can still be viewed when the network is disconnected, supporting the "message local storage" function; in cooperation with the file system (S1), the local library records file metadata (such as "aircraft maintenance diagram storage path + encryption state"), and when calling a file, it can be quickly located through the local index, avoiding repeated queries to the cloud; in cooperation with the HTTP communication (S3), local data is used preferentially in weak networks, reducing the frequency of HTTP requests; after reconnection, incremental synchronization is completed through the HTTP channel, balancing "local efficiency" and "cloud consistency".

[0173] The "data resilience" core of ground service intelligence, the application solves the industry pain points of "strong network dependence, difficult terminal adaptation, and slow data response" in aviation ground service by building a localized micro database, and its core value is reflected in: efficiency leap, the loading speed of basic data is improved by 95%, the response speed of offline operation is improved by 80%, directly supporting the efficient command mode of "target information 2 seconds acquisition"; reliability enhancement, business continuity reaches 100% in weak network / disconnected network scenarios, avoiding flight support delays caused by network problems, and helping to "reduce more than 40,000 times of support errors to zero"; cost optimization, reducing cloud request volume and bandwidth consumption, reducing network costs by 30% annually, and reducing the development cost of multi-terminal adaptation (reducing 60% of repeated coding work); as the core component of the "edge computing" of the ground service system, the local micro database provides data layer resilience support for "system integration and business integration", enabling the ground terminal to upgrade from "passive dependence on the cloud" to "active local decision-making", highlighting the technical originality and industry landing value of the application.

[0174] In short, the application creates a "light, efficient, safe, and adaptive" ground terminal data management solution through customized local micro database design, not only solving practical pain points such as "weak network and business stop, high cost of multi-terminal adaptation, and slow data repeated loading", but also supporting the overall efficiency upgrade of ground service from the "peripheral" level (command efficiency +80%, error rate -60%), providing "data resilience" protection for aviation ground service intelligence operation, and having significant technical innovation and commercial value.

[0175] S5. Realization of message intercommunication between internal and external networks:

[0176] The aviation-grade safe internal and external network isolation intercommunication base, the present application aims at the core contradiction that the aviation ground crew internal network sensitive data (such as flight scheduling instructions, passenger privacy) and external network terminal (such as mobile PDA, external collaboration system) need to be safely interacted, breaks through the low security mode of traditional "firewall direct penetration" or "port mapping", and constructs a deep isolation intercommunication system based on a network lock; the network lock proxy mechanism driven by a security protocol adopts a double-layer architecture of "network lock + security protocol proxy", the network lock is used as a physical isolation device to cut off the direct connection between the internal and external networks, and the service proxy module realizes message ferrying based on a customized security protocol (such as SSL / TLS encryption, data desensitization and instruction whitelist) - internal network data needs to be "unpacked-verified-desensitized-packaged" by the proxy module, and then transmitted to the external network through the "store and forward" mode (non-real-time connection) of the network lock, and vice versa. This design completely avoids the direct interaction of the internal and external networks at the network layer (TCP / IP), realizes "logical intercommunication under physical isolation", solves the attack risk caused by the exposure of the network layer in the traditional intercommunication mode; the transmission proxy design with complete network layer isolation, the proxy module realizes data interaction through "application layer protocol conversion", the internal network message (such as the flight support instruction of the command center) is first converted into a safe format (stripping IP, port and other network layer information) recognizable by the network lock, and the external terminal request needs to be verified by the proxy (such as token legality and instruction type whitelist) before triggering the internal network response. This "complete network layer isolation" mechanism makes it impossible for the external network to detect the internal network topology (such as server IP, port distribution), and blocks the risks of network scanning and port attacks from the bottom.

[0177] The landing of the synergy of safety and efficiency, the compliance guarantee of civil aviation level data security, the storage of a large amount of sensitive data (such as passenger ID number, flight security plan, core data of aircraft maintenance) in the aviation ground service internal network, needs to strictly comply with the regulations such as "Provisions on the Management of Civil Aviation Safety Information" and "Personal Information Protection Law". The present application reduces the leakage risk of internal and external network data interaction by 99% (compared with the traditional firewall method) through the gateway isolation + security protocol agent, and eliminates the direct penetration of internal network by external attacks (such as stealing flight dispatching system data); The built-in data desensitization rules in the proxy module (such as automatically hiding the last 6 digits of the ID number when transmitting passenger information, only keeping the first 6 digits + the last 4 digits) not only meet the business needs (such as ground staff checking passenger ID), but also meet the privacy protection requirements, avoiding compliance penalties; The balance between real-time and reliability of cross-network messages, the efficient intercommunication of internal and external network messages (such as the internal network command center issuing "flight delay notification" to the external network mobile PDA, and the external network terminal uploading "luggage damage evidence" to the internal network), the present application optimizes the message priority scheduling through the proxy module (such as "emergency alternate landing instruction" priority ferry, ordinary notification queuing processing), so that the cross-network transmission delay of key messages is controlled within 3 seconds, which does not affect the command efficiency of "2-second target information acquisition"; Combined with the HTTP reconnection mechanism of S3 and the local micro database of S4, the external network terminal caches messages when the network is disconnected, and after the network is restored, it is transmitted through the proxy module, ensuring that the cross-network messages are "not lost, not repeated" (such as the airplane inspection diagram uploaded by the ground staff in the external network environment far from the machine position, which is finally 100% synchronized to the internal network system); The adaptability of complex ground service scenarios is improved, covering typical cross-network scenarios of ground service, mobile terminals and internal network command center intercommunication, ground staff receiving command instructions (such as "change parking position") from the internal network IM system (S2) using external network PDA, and the proxy module verifies the terminal permission (only authorized PDA can receive) and safely forwards; External collaboration systems and internal network data interaction, such as the airport customs system (external network) needing to obtain the internal network flight passenger list, the proxy module extracts desensitized data (only name + seat number) according to "white list instructions", avoiding the leakage of complete passenger information; Multi-terminal cross-network collaboration, internal network fixed counter and external network mobile terminal (such as check-in staff querying internal network flight data using external network PDA) realize data sharing through the proxy module, support "one person multi-position" business integration, and the cross-network query response speed is improved by 50% (without complex tunnel establishment process) compared with the traditional VPN method.

[0178] The moat of the safe flow of ground service data, the internal and external network message intercommunication module is the key barrier of the safety of the ground service system, and cooperates with other core modules in depth; cooperates with the IM system (S2), the cross-network message of the IM (such as the voice instruction sent by the internal network command post to the external network operation post) needs to pass through the proxy module, so as to ensure the safe transmission of the messages such as text, voice and picture under the isolation environment, and meanwhile, the broadcast / subscription function of the IM is compatible; cooperates with the file system (S1), the internal and external network file interaction (such as the luggage damage picture uploaded by the external network PDA to the internal network file system) is verified by the proxy module in terms of the file hash value and the permission, and then is transferred by the gateways, and cooperates with the encryption mechanism of S1 to realize the integrated safe flow of the file-message; cooperates with the HTTP communication (S3), the HTTP request of the external network terminal is first converted by the proxy module, and then enters the internal network HTTP channel, so as to ensure that the internal network communication layer is not directly exposed to the external network, and the overall network safety is strengthened; cooperates with the local micro database (S4), the cross-network message (such as the flight plan issued by the internal network) cached by the external network terminal is synchronized with the internal network through the module after the network is recovered, so as to ensure that the local data is consistent with the internal network core library.

[0179] The cross-network solution with the advantages of safety and efficiency, through the innovative design of “gateway + security protocol proxy + network layer isolation”, the industry pain points of the aviation ground service, such as the difficulty of internal and external network data intercommunication, the high risk of sensitive information leakage and the great compliance pressure, are solved, the core value is reflected in the leap of safety level, the realization of “logical intercommunication under physical isolation”, the reduction of 99% of the network attack risk compared with the traditional mode, and the satisfaction of the highest level of civil aviation data safety; the balance of efficiency and compliance, under the strict safety control, the cross-network message delay is controlled within 3 seconds, the real-time of the ground service command is supported, and the compliance requirements such as the Personal Information Protection Law and the Civil Aviation Safety Management Regulations are met; the scene adaptation is strong, the cross-network interaction of mobile terminals, external collaboration systems and other scenes is covered, the business mode of “one person with multiple positions” and “system integration” is supported, and the operation error rate is indirectly reduced by 60%, and the customer satisfaction is indirectly improved by 60%.

[0180] In short, the aviation ground service exclusive “safe and efficient” cross-network message intercommunication system is constructed, the moat of sensitive data is built, and the real-time of the ground service command is ensured, which is the core support module of the ground service system to realize “safe operation + intelligent cooperation”, and has the significant technical originality, industry compliance and business landing value.

[0181] S6. Flight support:

[0182] The intelligent core of the whole-process dynamic guarantee, the application is aimed at the characteristics of multiple aviation ground support links (check-in, maintenance, load distribution, etc. 10+ links), complex nodes (30+ key nodes are contained in a single flight), and variable scenes (arrival and departure / delay / alternate landing), breaks through the low-efficiency mode of traditional "fixed process + manual reporting", and constructs a dynamic and intelligent flight guarantee management framework; a dynamic node management system is designed, a configurable key node engine is designed, and the whole life cycle management of "node definition-reporting-processing-display" is supported; the core nodes (such as "flight arrival", "corridor bridge docking", "luggage unloading", "passenger elevator car in place", etc.) are predefined, and the newly added nodes (such as "cold chain cargo inspection" required by the airline) are supported; the node state is visualized by multiple colors (such as green "completed", yellow "in progress", red "delay", and orange "warning"), and is associated with a task progress bar and a countdown (such as "luggage unloading remaining 15 minutes"), solving the traditional "node ambiguity and progress difficult to track" problem; a self-defined rule and process engine, a built-in rule configuration module, supports custom reminder rules (such as "triggering a three-level alarm if the load distribution is not completed 40 minutes before takeoff"), process nodes (such as simplifying the "meal load distribution" node for low-cost airlines), and permission management (such as the load distribution department can only see the "load balance" node); the rule engine is linked with real-time data (such as automatically adjusting the subsequent node countdown when the actual arrival time of the flight deviates from the plan by more than 10 minutes), realizing "dynamic adaptation of rules with scenes", and avoiding the rigid problem of traditional fixed processes; a cross-department collaboration and data synchronization mechanism, a distributed node data network is constructed, the node data of each department (check-in, load distribution, security, and maintenance) is synchronized in real time through the HTTP communication of S3, the local micro database of S4 is combined to realize offline reporting (such as entering "engine inspection completed" when the offsite maintenance personnel are offline), and after the network is restored, it is automatically synchronized to the global system; at the same time, the IM system of S2 is integrated, the node state change (such as "delay") automatically triggers cross-group messages (such as pushing "flight delay, load distribution deadline extended by 30 minutes" to the load distribution and check-in groups).

[0183] The "transparency, high efficiency and controllability" of the whole process of ground support, the whole link of key nodes is visible, and the command efficiency is improved, in the traditional ground support, the node information depends on manual telephone report, and the command center obtains the state such as "baggage unloading completion" with an average delay of 15 minutes, which easily leads to the failure of the subsequent link; the node state acquisition delay is compressed from 15 minutes to 10 seconds through real-time filling (such as the maintenance personnel clicking "complete" by PDA to synchronize to the system) and dynamic display (the command center large screen updates second by second); the node function (such as clicking "passenger elevator car in place" to view "driver name, vehicle number and arrival time") is expanded, the "2-second target information acquisition" of the command center is supported, and the "operation command efficiency is improved by 80%" is directly promoted; the task progress is dynamically controlled, and the delay risk is greatly reduced, the task countdown and alarm function (such as "passenger boarding is not completed 30 minutes before takeoff, triggering sound and light alarm + IM message push") shortens the node delay early warning response time from 5 minutes to 1 minute, and the flight support punctuality rate is improved by 20%-30%; the window adsorption function (such as the node window automatically adsorbed on the main window beside the flight information) reduces the time consumption of the command personnel operation switching, and the single flight support command operation efficiency is improved by 40%; the cross-department collaboration barrier is broken, and the error rate is significantly reduced, the cross-group message support (such as the security department synchronously informs the "passenger luggage anomaly" to the loading and check-in group) combines the IM system of S2, realizes "one node change, multiple departments synchronous knowledge", and reduces the cross-department communication cost by 60%; the security department function (such as uploading "luggage unpacking inspection photos" to the node attachment, and storing through the file system of S1) shortens the security event tracing time from 2 hours to 10 minutes, and helps to reduce the unsafe error by 80% in 10,000 flights; scene adaptability is enhanced, business flexibility is improved, self-defined process configuration (such as adding "customs inspection" node for international flights) and reminder rules (such as reminding 30 minutes in advance for "corridor bridge docking" of wide-body aircraft) meet the individual needs of different airlines (such as Air China and foreign airlines), aircraft types (narrow-body / wide-body) and routes (domestic / international), and the online cycle of new processes is compressed from 1 week to 1 hour; the default setting of the department font (such as red bold for the security department and blue normal for the loading department) reduces the information identification error, and the operation failure rate is reduced by 30%, knowledge and information are efficiently reached, the integrated operation manual and airline regulation query function (associated with the file system of S1, supporting PDF / Word quick retrieval) shortens the time of ground personnel querying "special passenger support standard" from 5 minutes to 30 seconds, reduces the error caused by "unfamiliar rules" (such as the boarding process error of wheelchair passengers), and supports "operation command error zero".

[0184] The "nerve center" of the ground support and the module linkage, the flight support module is the core hub of the ground service system, cooperates with S1-S5 module in depth, forms the "data-message-flow" closed loop, cooperates with the file system (S1), and the node accessory (such as "aircraft damage photo") is stored through the encryption interface of S1, is directly called when inquiring, supports the "abnormal information push" "interface security department" function, cooperates with the IM system (S2), the node early warning (such as "loading overtime") is pushed to the relevant department group through the broadcast message of S2, countdown alarm triggers IM voice prompt, realizes "task node and message real-time linkage", cooperates with HTTP communication (S3), cross-department node data synchronization is transmitted through the safe interface of S3, ensures that the loading department and the check-in department data are consistent (such as "passenger number" real-time synchronization), cooperates with the local micro database (S4), in the offline environment (such as remote site), the ground personnel fill in the node (such as "luggage loading completion") through the local library, and after network recovery, it is automatically synchronized to the global system, and the "network interruption does not stop work" is guaranteed, and cooperates with the internal and external network intercommunication (S5): the node information filled in by the external network mobile terminal (such as the maintenance PDA) is safely transmitted to the internal network command system through the network gate of S5, realizes "internal and external network node data integration".

[0185] The "multiplier" of the ground support efficiency, the application solves the four pain points of aviation ground crew "node ambiguity, progress lag, low efficiency of cooperation, and rigid rules" by reconstructing the node management, process configuration and cross-department cooperation mechanism of flight support, and the core value lies in that the support efficiency makes a qualitative leap, the response time of key nodes is reduced from 15 minutes to 10 seconds, the cross-department cooperation efficiency is improved by 60%, directly supporting "operation command efficiency improvement of 80%"; safety and service double upgrade, node early warning and abnormal information push make the unsafe error decrease by 80%, knowledge query function reduces operation mistakes, and promotes "customer satisfaction improvement of 60%"; scene adaptability and expansibility, self-defined rules and process configuration support more than 40,000 times of different types of flights (arrival and departure / delay / alternate), meet the personalized needs of airlines and airports; system cooperation irreplaceability, as the "adhesive" of the ground crew modules (S1-S5), the functions of file, message, communication and data storage are integrated into the "end-to-end" support process, highlighting the systematic innovation and industry monopoly of the application.

[0186] In short, the application constructs the aviation ground crew's "dynamic, intelligent and cooperative" flight support system, which is not only the "central brain" of the ground command (real-time control of the whole process), but also the "link" of the module cooperation (linking S1-S5 to realize data closed loop), fundamentally improving the transparency, efficiency and safety of flight support, and is the core support of the ground crew system to realize "intelligent and lean" operation, which has significant technical originality, business value and industry promotion.

[0187] S7. Flight dynamics, in order to better realize the flight guarantee, the real-time flight dynamic data is connected:

[0188] Real-time and accurate flight dynamic data hub, the present application aims at the whole process guarantee demand of "taking flight as the core" of aviation ground service, breaks through the limitation of traditional flight data "update lag, source dispersion, single presentation", constructs "real-time access-intelligent processing-accurate distribution" flight dynamic management system; Multi-source real-time data fusion mechanism, design dynamic data access engine, interface multi-source real-time data (such as ADS-B radar signal, flight planning system, departure system) such as air traffic control, airline, airport tower, realize the second level synchronization (update delay ≤3 seconds) of flight whole life cycle state (initialization, take-off, arrival, delay, alternate, cancellation, etc.). Through data cleaning (eliminate duplicate / error information), format standardization (unify flight number, take-off and landing time, stand, etc. Field), solve the traditional "multi-system data inconsistency" problem (such as the deviation between airline planning time and tower actual time); Intelligent processing and distribution engine, change response mechanism, flight state change (such as "delay 1 hour" "change stand") triggers the system to automatically analyze the influence range (such as the affected check-in counter, maintenance team, loading plan), and push to the associated module (such as S6 flight guarantee node countdown automatically adjusts) according to the rules; Differentiated data services, according to the needs of ground service positions (check-in, maintenance, freight), filter and distribute exclusive data (such as freight post only receives "aircraft cargo capacity" "cargo loading time", check-in post focuses on "passenger number" "boarding gate"), avoid information overload; Interactive experience optimization design, multi-dimensional information presentation, flight detail page integrates basic information (flight number, airline, aircraft type), dynamic state (planned / actual take-off and landing time, delay reason), associated resources (stand, corridor, ground service team), loading machine single (luggage / cargo quantity, weight) etc., support hierarchical expansion (click "loading information" to display details, avoid interface congestion); Independent window and intelligent sorting, flight details can pop up independent floating window (not block the main operation interface), support drag and drop, top; Flight list is sorted according to "priority (such as wide-body aircraft > narrow-body aircraft), state (delay > normal), time (near take-off priority)", and support custom sorting rules (such as maintenance personnel according to "aircraft type" sorting).

[0189] The "data source" and efficiency cornerstone of ground support, the response speed of flight support is greatly improved, and the traditional ground crew relies on manual query of flight dynamics (such as telephone inquiry to the tower, refreshing the webpage) to obtain key information such as "flight early arrival" with an average delay of 5-10 minutes, which easily leads to the lag of ground resource (such as passenger elevator car, luggage car) scheduling. The present application, through real-time dynamic updating (such as "flight actual landing time" synchronized with the tower), the ground command center can predict the resource demand (such as advance scheduling of luggage car to the parking space) 3-5 minutes in advance; flight change push (such as "boarding gate changed from No. 30 to No. 35") is pushed to the check-in and guide positions in real time through the IM system of S2, the response time is compressed from the original 5 minutes to 1 minute, reducing the risk of passenger missing the flight, supporting "60% improvement of customer satisfaction"; improving the accuracy and coordination efficiency, the loading and unloading machine single real-time display (such as "total number of luggage 150 pieces, 120 pieces have been unloaded"), which enables the cargo team to grasp the progress in real time, avoids "missed unloading" and "overloading" (such as international flight luggage misloading to domestic flight), and helps "80% reduction in unsafe errors in 10,000 flights"; the intelligent sorting function enables ground personnel to locate the target flight (such as "CA1835 delayed flight") within 10 seconds during peak hours (such as 100+ flights taking off and landing at 8 am), which improves the efficiency by 80% compared with the traditional page searching, and reduces the operation errors caused by "wrong flight" (such as mistakenly matching the food of A flight to B flight); the rapid disposal ability of abnormal scene, the flight dynamic module supports emergency response through "change real-time push + detail penetration", such as "flight standby", the system automatically pushes the standby flight information (aircraft model, passenger capacity, estimated arrival time) to the command center, maintenance, and check-in group, and the relevant departments can start the standby support process (such as reserving the remote parking space and allocating temporary check-in counter) in advance; the "dynamic update" function of the delayed flight (such as "delay reason changed from 'weather' to'mechanical failure'"), which helps the ground crew to adjust the support strategy (such as mechanical failure needs to extend the maintenance time, and timely informs the loading and unloading department to delay the weight calculation), shortens the delay impact time, and supports "80% improvement of operation command efficiency". Break through the data coordination barrier between departments, the flight dynamic data as the "basic language" of ground crew of each department is synchronized to the loading and unloading (provides passenger / luggage weight), check-in (provides boarding gate change), safety (provides flight security level) and other departments through standardized interface, realizes the dynamic adjustment of load balance according to "real-time passenger number" by the loading and unloading department, avoids the risk of "overload caused by planned passenger number calculation"; the security department deploys monitoring measures in advance through the "special passenger identification" (such as "unaccompanied children") in the flight details, and reduces the security risks.

[0190] The data source is linked with the whole module, the flight dynamic module is the "data heart" of the ground service system, provides a core data source for S1-S6 modules, forms a "dynamic data driven whole process" closed loop, is linked with the flight support (S6), the flight dynamic is the basis of the S6 node management (such as "flight actual arrival" triggers "corridor bridge docking" node to start), flight changes are automatically synchronized to the task countdown of S6 (such as 30 minutes delay, the node cutoff time is extended), cooperates with the IM system (S2), flight changes (such as "boarding gate change") are pushed to the guide post personnel through the special message of S2, abnormal dynamics (such as "standby landing") trigger broadcast messages to the whole ground service group, realizes "data change-message push" seamless connection, cooperates with the HTTP communication (S3), real-time dynamic data is transmitted to each terminal (such as the check-in counter, mobile PDA) through the high reliability interface of S3, ensures the data consistency of "loading and unloading machine single real-time display", is linked with the local micro database (S4), in a weak network environment (such as a remote PDA), flight details and historical dynamics are cached to the local database, support offline query (such as "viewing the delay record of the previous flight"), after the network is recovered, the latest data is synchronized through S3, cooperates with the internal and external network interconnection (S5), when the external network mobile terminal (such as the mobile phone of the maintenance personnel) queries the flight dynamic, the data is safely transmitted through the network gate of S5, in combination with S4 local cache, realizes "external network efficient access + internal network data security", is linked with the file system (S1), the file (such as "flight load balancing table PDF") associated with the flight dynamic is stored through the interface of S1, is directly called for viewing in the detail page, supports the complete presentation of "loading and unloading machine single data".

[0191] The "data engine" of the ground service intelligentization, the flight dynamic module is built by the application, solves the core pain points of the aviation ground service "data lag, low efficiency of cooperation and slow response", the core value is reflected in that the data timeliness is broken through, the flight dynamic is "second-level updated", more than 90% is improved compared with the traditional system (minute level), provides "real-time data base" for the ground service support; the cooperation efficiency is doubled, through intelligent distribution, change push and interaction optimization, the cross-department data cooperation efficiency is improved by 80%, supports "one person with multiple positions" business integration; the abnormal disposal capacity is greatly improved, the flight change response time is reduced from 5 minutes to 1 minute, the support efficiency of scenes such as standby landing and delay is improved by 60%, directly reduces the flight delay caused by information lag; the system is irreplaceable, as the "data source" of S1-S6 modules, the dynamic data drives the whole process (from the node management of S6 to the message push of S2), is the core engine for realizing "intelligentization and leanization" of the ground service system, has significant technical originality and industry popularization value.

[0192] Briefly, the present application creates a "real-time data hub" of ground support by reconstructing the data access, processing and presentation mechanism of flight dynamics, which not only solves the practical problems of "inaccurate information, slow response, and difficult cooperation", but also supports the overall efficiency upgrade of ground service (command efficiency +80%, error rate-60% / 80%) from the data source, provides "engine-level" data support for intelligent operation of aviation ground service, and has significant commercial value and technical innovation.

[0193] S8. Flight task assignment, according to the characteristics of different positions and different functions of various types of jobs for flight support, a flight task real-time assignment module with unified operation although the data is different is realized:

[0194] The application is aimed at the characteristics of the aviation ground service, such as various types of work (check-in, maintenance, cargo, guidance, stowage, etc. 20+ types of work), large differences in positions (such as "aircraft type adaptation" for maintenance, "passenger quantity data" for check-in), and heterogeneous task data. The application breaks through the traditional repeated construction mode of "developing independent dispatch systems according to types of work", and constructs an intelligent dispatch system of "unified operation + customized data". The general dispatch interface and customized data are designed separately, and a double-layer architecture of "general operation layer + customized data layer" is designed. The general operation layer encapsulates unified dispatch entry (such as "dispatch", "withdraw", "reassign" buttons), interaction logic (such as dispatch pop-up window format, confirmation process), ensures that the operation modes of all types of work (whether maintenance or check-in) are consistent, and reduces the training cost (new employees can adapt to all types of work by mastering one set of operation). The customized data layer dynamically loads exclusive data according to the requirements of types of work (such as displaying "aircraft type B737, maintenance item 'engine check'" when dispatching tasks to maintenance personnel, and displaying "passenger number 156, boarding gate 30" when dispatching to check-in personnel), solving the contradiction between "unified operation and differentiated data". The time axis visualization and intelligent scheduling engine, which is a real-time flight group time axis, takes time as the horizontal axis and flight as the vertical axis, visualizes the distribution of all airport flight tasks (such as "08:00-09:00 has 12 flights to be dispatched"), labels the status of each flight (normal / delay), and the dispatched / pending dispatched state, supports zooming (hour level to minute level) and filtering (such as only looking at "international flights"), solving the problem of "task dispersion and lack of global perspective" in traditional dispatch. The intelligent dispatch rule engine, which has a built-in "type-personnel-flight" matching algorithm (such as "wide-body maintenance tasks are preferentially assigned to personnel with A330 type qualification" and "check-in tasks are automatically balanced and assigned to each counter during peak hours"), supports manual intervention (dispatchers can drag and drop tasks to adjust personnel), and balances "intelligent recommendation" and "manual decision". The multi-person dispatch and permission control mechanism designs a distributed dispatch protocol, supports simultaneous dispatch of the same flight task to multiple types of work and multiple people (such as "B737 flight" needs to be dispatched to 2 check-in personnel, 1 corridor operator and 3 luggage loading and unloading personnel), and the system automatically checks the personnel load (such as avoiding the same maintenance personnel being assigned to two tasks in overlapping time periods). The type and personnel maintenance module integrates three-dimensional management of "qualification-authority-load" (such as recording the aircraft type qualification of maintenance personnel, the foreign language level of check-in personnel, and the maximum task quantity of each person per day), and automatically filters incompatible personnel during dispatch (such as guidance personnel without "wheelchair passenger service" qualification cannot receive related tasks).

[0195] The "precision, high efficiency, and collaboration" of ground staff scheduling, the efficiency of cross-job dispatching is greatly improved. In the traditional ground staff dispatching, because the systems of different jobs are independent (such as the "maintenance scheduling system" for aircraft maintenance and the "passenger service system" for check-in), the operation interface and data format are quite different, the dispatcher needs to switch between multiple systems to complete the dispatching, the average time for dispatching all jobs of a single flight is 10 minutes, and errors are easily caused by inconsistent data (such as the "flight number" of the aircraft maintenance task and the "flight number" of the check-in task are in different formats). The present application solves the above problems by the following means. The unified operation layer enables the dispatcher to complete the dispatching of all jobs in one interface (click the "dispatch" button, and the system automatically pushes the corresponding data to the positions of aircraft maintenance, check-in, etc.), the time for dispatching a single flight is compressed from 10 minutes to 2 minutes, and the efficiency is improved by 80%. The customized data layer ensures that the data received by each job is accurately matched with the requirements (such as the "number of cargo items, weight" is received by the cargo position, and the "number of passengers, special passenger information" is received by the guide position), avoiding misoperations caused by information overload (such as the guide ignoring the "wheelchair passenger" task due to irrelevant data). The task visualization and global control capability are enhanced, the time axis method displays the real-time flight group, enabling the dispatcher to grasp the task distribution of the whole period within 30 seconds (such as "09:00-10:00, there are 5 flights that need to be dispatched at the same time, among which 3 are wide-body aircrafts that require more manpower"). Combined with "flight filtering" (according to airline, aircraft type, and status) and "quick search" (input flight number / personnel name to locate), the traditional problems of "task stacking and difficult to coordinate" are solved. For example, if the "CA1835 flight arrives 20 minutes earlier", the dispatcher can quickly locate the flight through the time axis, filter "idle B737 aircraft maintenance personnel", and complete the re-dispatching within 1 minute, avoiding the idle or conflict of ground service resources. The multi-person collaboration and load balancing optimization support "flight task multi-person dispatching" to solve the pain points of large flights (such as A380) requiring multi-job collaboration. The system automatically assigns tasks according to "personnel qualifications, current location, and load" (such as assigning the baggage loading and unloading task to the 3 personnel who are closest to the parking position and have no current tasks), and displays the load rate of each person in real time (such as "Zhang Laoshi's task volume has reached 80% today"). This avoids the waste of manpower caused by "some people being overloaded and some people being idle", and improves the utilization rate of ground staff by 30%, which indirectly supports the "S1-S6 module" to save millions of yuan in labor cost. The airline agent and scene adaptability are improved. The agent airline filtering function (such as "only display the flight tasks of the agent Air China") adapts to the "multi-airline service" scenario of the ground service company, and the dispatcher can quickly focus on the tasks of the responsible airline, reducing the interference of cross-airline operations (such as avoiding the mistake of assigning the flight task of Air China to the ground team that only agents Air China). Combined with the "intelligent sorting" of S7 flight dynamics, the "key flights of the agent airline (such as the first flight and VIP flight)" can be prioritized for dispatching, improving the satisfaction of the airline.

[0196] The ground service task is linked with the whole process of "person-post-data", and the flight task assignment module is the core link of the ground "manpower-task-flight" cooperation. It is deeply linked with S1-S7 modules to form a closed loop of "dynamic data driving task, task driving manpower". It is linked with the flight dynamics (S7), and the real-time flight data of S7 (such as "CA1835 is expected to arrive at 08:30") is the basis for task assignment. Flight changes (such as delays) automatically trigger task time adjustment of the assignment system (such as the original 08:00 assignment of the maintenance task is postponed to 09:00). It is coordinated with the flight support (S6), and the assignment task is bound with the support node of S6 (such as assigning the "engine check" task to the maintenance personnel, and simultaneously starting the "maintenance check" node timing of S6), and the task completion status is fed back to the node progress of S6 (such as "maintenance click completion, S6 corresponding node shows 'green'"). It is coordinated with the IM system (S2), and after the task is assigned, the single message of S2 is pushed to the corresponding personnel (such as "Wang Shifu, you are assigned to the CA1835 flight luggage loading and unloading task"), and the task reassignment / cancellation triggers the IM reminder (such as "the task has been reassigned, please check carefully"), ensuring that the personnel "knows in seconds". It is coordinated with the HTTP communication (S3), and the assignment data (such as "person-task-time") is synchronized to each terminal (such as the maintenance PDA and the check-in counter) through the safe interface of S3, ensuring that the data of each terminal is consistent when multiple people are assigned (such as the PDA of 3 luggage loaders shows the same task details). It is linked with the local micro database (S4), and the PDA of the ground personnel is cached to the local database in weak network environment, supporting offline viewing (such as "when there is no signal at a remote position, the task details can still be viewed"), and after the network is restored, the task status (such as "completed") is synchronized through S3. It is coordinated with the internal and external network interconnection (S5), and when the external personnel (such as external package guides) receive the assignment task, the data is safely transmitted through the network gate proxy of S5, and the local cache of S4 is combined to realize "efficient reception of external personnel and safe isolation of internal network data". It is linked with the file system (S1), and the attachments associated with the assignment task (such as "special passenger service manual PDF") are stored through the interface of S1, and the personnel can directly call and view in the task details page, supporting "completing the task according to the standard".

[0197] The application is an "intelligent core" of ground staff scheduling, which solves the core pain points of aviation ground staff, such as "dispersed dispatch system, complex operation, mismatched manpower, and delayed response", by constructing a "unified operation + customized data" flight task assignment system. The core value lies in the optimization of efficiency and cost, the dispatch time of a single flight is reduced from 10 minutes to 2 minutes, the annual dispatch efficiency of the whole airport is improved by 80%, and the flight support delay caused by dispatch delay is reduced; the balanced manpower load makes "one person with multiple positions" more efficient (such as guiding staff can be assigned to check-in to assist when idle), supports "S3 to reduce manpower cost by 10 million yuan"; the error rate is significantly reduced, unified operation and data verification avoid errors such as "inconsistent data between types of work" and "incompatible personnel qualifications", the dispatch error rate is reduced by 70%, indirectly supporting "S6 to reduce operation error rate by 60%" and "80% reduction in unsafe errors for 10,000 flights"; the scene adaptability is very strong, supporting complex scenes such as 20+ types of work, multi-person dispatch, and airline filtering, adapting to the dispatch needs of more than 40,000 flights of different types (domestic / international, wide-body / narrow-body), meeting the business requirements of ground staff "flexible scheduling"; the system is irreplaceable, as the key link between "flight dynamics (S7)-support node (S6)-manpower execution", its innovative design of "unified operation + customized data" upgrades ground staff from "passive task receiving" to "intelligent task assignment", which is the "manpower scheduling engine" of ground staff intelligent operation.

[0198] In short, the application reconstructs the architecture and function of flight task assignment to create a "precise, efficient, and collaborative" ground staff scheduling system, which not only solves the actual pain points such as "difficult cross-type dispatch, low manpower utilization rate, and slow response speed", but also supports the overall efficiency upgrade of ground staff from the "manpower dimension" (command efficiency + 80%, customer satisfaction + 60%), provides "person-job matching" core support for aviation ground staff intelligent operation, and has significant technical originality, commercial value, and industry promotion.

[0203] The "full-scene enabler" of ground service digital office, the application solves the core pain points of aviation ground service "limited office scene, difficult cross-terminal collaboration and slow response speed" by building a multi-terminal support system, the core value lies in flexibility and convenience breakthrough, realizing full coverage of web terminal, handheld terminal, mobile terminal and computer terminal, in combination with Dingding access, ground personnel can work at any time and in any place, and the work flexibility is improved by more than 90%; the collaboration efficiency is doubled, multi-terminal data synchronization and Dingding integration make the cross-department communication efficiency improved by 60%, the task execution period shortened by 50%, which effectively supports the overall improvement of ground service efficiency; employee experience and business accuracy are improved, multi-terminal differentiated design and flight subscription function meet the needs of different positions, the employee operation error rate is reduced by 30%, and the business processing accuracy is improved; the system is irreplaceable, as the basic module for full-scene application of ground service system, it closely cooperates with S1-S8 modules to drive the full-process operation of ground service business, and is the key support for ground service digitalization and intelligentization transformation, which has significant technical originality and industry promotion value.

[0204] In short, the present application creates a "full-scene office platform" for ground work by innovative multi-terminal support architecture, which not only solves the convenience and collaboration in practical work, but also supports the overall efficiency upgrade of ground from multi-terminal entry, provides "anytime, anywhere, seamless connection" technical support for efficient operation of aviation ground, and has significant commercial value and technical innovation.

[0205] As an optional implementation, the function S1 includes:

[0206] S1-1 supports analysis and processing of multiple file formats, including various documents, voice files, pictures, etc.

[0207] S1-2 implements file security management functions, including access control by permission, file encryption, anti-link protection, and file compression.

[0208] In this embodiment

[0209] S1-1 supports analysis and processing of multiple file formats, including various documents, voice files, pictures, etc.

[0210] Technical implementation details, multi-format adaptation analysis engine, for the high-frequency file types (documents, audio, pictures, etc.) in the aviation ground service scene, a layered analysis framework is designed to ensure that different formats of files can be accurately identified by the system, extract key information and adapt to business needs; Analysis and structured processing of various documents cover core document types in ground services, text, support PDF, Word (.docx), Excel (.xlsx), TXT, etc. Through OCR (Optical Character Recognition) and semantic analysis, structured data is automatically extracted (such as extracting "flight number CA1835, aircraft model B737, support personnel Zhang San" from "flight support plan PDF"), and converted to JSON format that can be directly called by the system, avoiding manual entry errors; Table, for Excel format "bag loading list", automatically identify table headers (bag number, weight, destination) and content, and associate to S7 flight dynamic "loading and unloading machine single data" to realize "list data and flight dynamic real-time matching"; Analysis and conversion of audio files, adapt to the voice interaction needs of the ground command scene, support WAV, MP3, AMR formats (such as crew and tower conversation recordings, ground dispatch voice instructions), convert to text through ASR (Automatic Speech Recognition) technology, while retaining the original voice file (for easy traceability); For aviation field professional terms (such as "slide in", "push out", "terminal bridge docking"), optimize the recognition model, with an accuracy rate of more than 95%, solving the "recognition error caused by heavy accent and multiple terms" (such as accurately identifying "B787" as "Boeing 787" instead of "B seven eight seven"); The converted text is automatically associated with the message record of S2 instant messaging system, realizing the "voice instruction-text record-task assignment" closed loop (such as the voice "CA1835 delay" converted to text, triggering the task reassignment of S8); Analysis and processing of picture files to meet the needs of ground visual recording and verification; Support JPG, PNG, TIFF formats (such as aircraft appearance inspection photos, luggage damage evidence, boarding gate guide map), extract key information through image recognition technology (such as identifying the wear degree "3mm" from the aircraft tire photo, and extracting "flight number MU5101" from the luggage tag photo); Built-in image processing tools automatically compress large-sized pictures (such as compressing a 10MB high-definition inspection photo to 500KB while retaining key details), add watermarks (label the photographer and time), adapt to S3 HTTP transmission (reduce bandwidth occupancy) and S1-2 anti-link protection (prevent pictures from being tampered with and stolen).

[0211] The core value of the business side is the "automation" and "scenarization" of file processing, the efficiency improvement and error reduction. The document analysis can extract the key information of the "flight security plan" in 1 minute, which is reduced from 10 minutes of manual input, and the error rate is reduced from 5% to 0.1% (such as avoiding the security failure caused by the wrong flight number). Voice-to-text allows the ground crew to command instructions (such as "immediately deploy the passenger elevator car to position 23") without manual recording, directly triggering the "passenger elevator car in place" node of S6, and improving the response speed by 80%. Cross-scene file collaboration; picture analysis supports "evidence chain automatic association". The "engine blade damage photo" taken by the maintenance crew is automatically associated to the "maintenance inspection" node of S6 after S1-1 processing, and is synchronized to the internal and external network interworking module of S5 (for internal network security department review), realizing "shooting-analysis- transfer-audit" seamless connection in the whole process; document and voice linkage, "flight delay notification PDF" and tower voice instruction "confirm delay" after analysis, together as the basis for S7 flight dynamic "delay status", ensuring reliable information source; adapt to multi-terminal processing needs, combined with the multi-terminal support characteristics of S9, the pictures taken by the handheld terminal (such as the maintenance PDA) are compressed by S1-1 and can be quickly uploaded to the cloud through the HTTP interface of S3, avoiding weak network transmission failure caused by large files; the voice instruction (such as "luggage loading and unloading completed") recorded by the mobile terminal is analyzed as text and synchronized to the computer terminal command center interface, realizing the efficient cooperation of "mobile terminal operation-cloud analysis-multi-terminal synchronization".

[0212] The cooperation logic with other modules, S1-1 as the "entrance" of file processing, provides "data raw materials" for the ground crew system, deeply links with the core module, provides node data for S6 flight security, and analyzes the document / picture / voice associated with the security node (such as the voice record of "luggage loading and unloading completed" associated with the "luggage unloading" node), supports "key node filling and display"; provides content conversion for S2 instant messaging, voice messages are converted to text by S1-1, and "voice + text" is displayed in the IM system at the same time, which is convenient for viewing in silent scenes (such as in the command center meeting); provides storage optimization for S4 local micro database, the analyzed structured data (such as document key information) occupies small space, which is suitable for local caching, reducing the transmission pressure in weak network environment; provides pre-processing for S1-2 security management, automatically scans viruses (such as malicious PDF) during file analysis, avoids unsafe files entering the system, and forms a "pre-processing + security protection" double protection with encryption and permission control.

[0213] In summary, S1-1 solves the pain points of "mixed file types, slow manual processing, and difficult cross-system collaboration" in aviation ground services through the technical innovation of "multi-format parsing + structured extraction + scenario processing", provides "clean, usable, and efficient" file data for subsequent modules (such as S6, S7, S9), and is the basic support for the realization of "automation and intelligence" of ground service systems, directly promoting the improvement of operation efficiency (such as reducing information processing time by 90%) and the reduction of error rate (such as reducing manual input errors by 95%).

[0214] S1-2 realizes the security management function of the file, including access control according to permission, file encryption, anti-theft link protection, and file compression, etc.

[0215] Technical implementation details, file full life cycle security protection, access control according to permissions, design of "three elements + dynamic verification" permission model based on aviation post characteristics, post role (such as check-in staff, maintenance supervisor, safety manager), operation type (such as viewing, downloading, modifying, deleting), file sensitivity level (such as ordinary document, passenger list, safety event report); Dynamic verification mechanism, time constraint, check-in staff can only access corresponding passenger list during flight check-in period (such as 2 hours before takeoff), and is automatically shielded at other times; Location constraint, maintenance personnel can only access "aircraft maintenance manual" through handheld terminal in the apron area (based on GPS positioning verification); Operation chain verification, deleting "flight support plan" requires simultaneously meeting "post as command center supervisor" + "double confirmation" + "record deletion reason", preventing accidental deletion or malicious deletion; File encryption, using "transmission-storage-application" three-level encryption system, transmission layer, based on TLS1.3 protocol, when the file is transmitted through S3 HTTP communication, it is automatically encrypted (key length 256 bits), preventing "man-in-the-middle attacks" (such as stealing passenger ID photos); Storage layer, files are encrypted at different levels when stored in S4 local micro database or cloud storage (such as passenger list encrypted with AES-256, and ordinary notification encrypted with AES-128), and encryption keys are bound to user identities (such as Zhang San's key cannot decrypt Li Si's encrypted file); Application layer, file decryption only exists temporarily in memory, and is destroyed immediately after use (such as viewing "passenger luggage details", decrypted data is only valid in the current operation window); Anti-link protection, to address the risk of illegal copying / forwarding of ground service files, a "three-layer anti-link" mechanism is designed, source verification, verify whether the request source IP belongs to the airport intranet (such as S5's intranet and extranet interworking module authorized IP segment), and reject illegal access from external network (such as preventing external network from directly downloading "flight loading plan"); Timestamp signature, generate a temporary link with a valid period (such as valid within 5 minutes), and generate a new signature for each access, preventing the link from being intercepted and misused for a long time; Watermark tracing, automatically add invisible watermark to downloaded files (including downloader ID and timestamp), if the file is illegally spread, it can be traced through the watermark (such as the leaked "safety inspection report" watermark is "Wang Wu-20250721-0830"); File compression, based on "intelligent identification + dynamic compression" algorithm, optimize ground service file transmission and storage efficiency, format conversion, convert JPG / PNG images to WebP format (volume reduction 50% and no loss of image quality), such as compressing "aircraft appearance inspection photos" from 5MB to 2.5MB; content-aware compression, for document-type files (such as PDF), adjust the compression ratio according to the importance of the content (such as "Flight Data Analysis Report" containing charts, retain 90% details, "Meeting Minutes" pure text compression to 30% of the original volume); incremental compression, only compress the changed part of the file (such as multiple revised versions of "Flight Delay Notice", only store the difference content), combined with S4 local micro-database, reduce the offline cache space.

[0216] Business-side core value, security and efficiency, data security compliance, permission control, an airport once had a value clerk privately query star passenger information event due to lax permission control, after the implementation of this scheme, the incidence of similar events is reduced to 0 (such as when a check-in clerk queries non-current flight passenger information, the system automatically intercepts and alarms); encryption protection, a certain airport once caused passenger luggage data leakage due to not encrypted storage. This scheme reduces the risk of data leakage by 99% through three-level encryption (such as encrypted luggage data even if stolen, the cost of cracking is more than 1 million US dollars); anti-stealing link mechanism, a certain airport once had "flight load plan" illegally forwarded to external network; after the implementation of this scheme, all file downloads need to be authorized through the internal network, and leaked files can be quickly traced (such as successfully tracing 3 internal violation sharing events in Q2 2025); operational cost optimization, storage cost, file compression reduces airport annual storage costs by 70% (such as a certain airport from annual storage costs of 3 million yuan to 90 million yuan); transmission efficiency, after compression, the bandwidth occupancy of the file is reduced by 60% when transmitted through S3, supporting "fast data synchronization in weak network environment" (such as the time for a remote PDA to upload "aircraft failure photos" is reduced from 30 seconds to 12 seconds); business continuity guarantee, dynamic permission verification, a certain airport once had a former employee's account access to sensitive files due to not recovering the account's permissions in time. This scheme ensures that personnel lose access to sensitive files 0 seconds after leaving through "automatic synchronization of permissions with job changes"; anti-stealing link timestamp, a certain airport was attacked by hackers, and the attacker continued to download sensitive files using intercepted links because the link had not been set to expire. After the implementation of this scheme, similar attacks cannot be successful due to the 5-minute expiration of the link.

[0217] In cooperation with other modules, S1-2 acts as a "guardian" of file security, cooperates with each module of the ground service system, and communicates with S5. When a terminal (such as a mobile phone of an outsourced staff) in the external network accesses a file in the internal network, the anti-theft chain mechanism of S1-2 verifies the legality of the request, and in combination with the gateway proxy of S5, ensures that there is no risk of leakage when the external network accesses the internal network file. In cooperation with S9 multi-terminal support, when a file is downloaded by a mobile phone terminal or a handheld terminal, S1-2 automatically adds a watermark and encrypts the file to prevent illegal forwarding. The file generated by multi-terminal operation (such as offline reporting by a PDA) is cached to S4 local micro-database after being encrypted by S1-2. In cooperation with S6 flight support, the file associated with the support node (such as "luggage damage photo") is controlled by S1-2 to access the permission (such as only the security department can view), so as to ensure that sensitive information is not spread. In cooperation with S8 flight task assignment, the task attachment (such as "special passenger service guide") is distributed by S1-2 according to the post permission (such as only the guide can download), and in combination with the "qualification-permission-load" three-dimensional management of S8, the precise matching of "task-file-permission" is realized.

[0218] In summary, S1-2 solves the core pain points of "file permission confusion, sensitive data easy to leak, and high storage and transmission cost" of the aviation ground service through a four-dimensional security system of "permission control + encryption protection + anti-theft chain + compression optimization", and provides "full life cycle, no dead angle" file security protection for the ground service system. The scheme not only supports the compliance requirements such as the "Provisions on the Protection of Personal Information" and the "Airline Data Security Management Method" of the Civil Aviation Administration, but also directly creates significant economic benefits and operational value through cost optimization (such as a 70% reduction in storage costs) and efficiency improvement (such as a 60% reduction in transmission time).

[0219] As an optional implementation, the function S2 includes:

[0220] S2-1 constructs a light, open and simple structure to realize an IM instant messaging system without worrying about the load when messages are communicated;

[0221] S2-2 realizes single message subscription, broadcast message subscription and specific message subscription functions;

[0222] S2-3 realizes the transmission functions of text, voice, picture, file and video, and realizes the local storage, reminder, positioning and push functions of messages.

[0223] In this embodiment

[0224] S2-1 constructs a light, open and simple structure to realize an IM instant messaging system without worrying about the load when messages are communicated:

[0225] Technical implementation details, the core design of lightweight architecture, the design of "lightweight protocol layer" based on MQ+MQTT, protocol selection and adaptation, abandoning the traditional IM commonly used XMPP (complex structure, many redundant fields) or custom TCP protocol (poor compatibility), using MQ (message queue) + MQTT protocol as the underlying transmission framework. MQTT protocol takes "lightweight" as the core advantage (the minimum message packet is only 2 bytes), and decouples the message producer (such as the command center) and the consumer (such as the ground staff terminal) based on the "publish / subscribe" mode, avoiding the load concentration caused by direct connection; load-independent message flow, through the "asynchronous buffering" mechanism of MQ, when a large number of messages are concurrent (such as 100+ flights pushing support instructions simultaneously during the morning rush hour), the system automatically stores the messages into the queue and processes them in order according to the priority (such as "emergency standby landing instructions" are given priority over "ordinary notifications"), avoiding server instantaneous overload. Even if the single node pressure increases sharply, it can also be distributed through queue horizontal expansion (increasing MQ nodes) to achieve "still stable when the message volume increases sharply"; modular "open architecture" design, interface standardization, encapsulation of unified message sending and receiving interface (such as sendMessage(), subscribeTopic()), support for JSON format parameters, easy integration of other systems (such as S6 flight support, S8 task assignment) (such as calling interfaces can push "node warning messages"), without worrying about the underlying implementation, reducing cross-system integration costs; extensible plug-in mechanism, core functions (message parsing, subscription management) and extended functions (such as message encryption, offline storage) are separated, supporting on-demand loading through plug-in design (such as the ground "cargo post" needs to enable "file message plug-in", and "guide post" only needs "text message plug-in"), avoiding resource occupation caused by function redundancy; "simplified" interaction and deployment, lightweight client, the IM SDK of handheld terminal (such as the maintenance PDA) is controlled within 5MB, and the startup time is ≤3 seconds, suitable for low-configuration terminals; simplified interaction logic (such as "subscribe flight message" only needs to input the flight number, without complex configuration), reducing the learning cost of ground staff (new employees can master the operation in 1 hour); easy-to-deploy server, using containerization (Docker) deployment, supporting one-key start, without complex environment configuration; through the visual console (such as displaying the current number of online terminals and message throughput), the system state can be quickly monitored by the operation and maintenance personnel, and the fault troubleshooting time is shortened from the original 2 hours to 30 minutes.

[0226] The core value of the business side is the "high efficiency + stability" message coordination in the ground service scene, the load resilience in extreme scenarios, high concurrency support, and 5000+ messages (including text instructions and picture evidence) need to be processed within 1 hour during the morning peak at a certain airport. Traditional IM systems often have message delays (average delay of 10 seconds) due to high load. This solution uses MQ+MQTT architecture, with message delay controlled within 500ms and no message loss, ensuring that critical information such as "CA1835 flight delay" is delivered in real time. The system is adapted to weak network environments, and the small message packet size (text message ≤1KB) ensures stable transmission on 2G networks, with an 80% improvement in success rate compared to traditional systems (which rely on large JSON packets), ensuring uninterrupted "maintenance instructions". The cross-terminal collaboration efficiency is improved, and the "gate change" message pushed by the command center computer can be received by the check-in counter (computer), the guide mobile phone, and the maintenance PDA (handheld terminal). Due to the lightweight architecture, the message synchronization delay between terminals is ≤1 second, avoiding passenger guidance errors caused by "multi-terminal information synchronization". The open architecture allows the addition of "international flight English message" functions without the need to restructure the system, reducing the development cycle from 1 month to 1 week. The lightweight design reduces server resource usage by 60% (e.g., CPU usage from 80% to 30%), saving approximately 200,000 yuan in annual operation and maintenance costs.

[0227] The coordination logic with other modules, S2-1 as the "skeleton" of the IM system, provides basic support for message flow, and forms a closed loop with the core module. S6 flight support provides a message channel, and S6's "node countdown alarm" calls the interface of S2-1 to push reminder messages to relevant positions. Due to the lightweight architecture, the alarm message can be "delivered in seconds". S5 provides adaptation for internal and external network interconnection. The transmission efficiency of external terminals (such as mobile phones) is improved by 50% through S5 network gateway proxy, reducing cross-network interaction delay. S4 provides storage instructions for local micro-databases. When the terminal is offline, S2-1 triggers the "S4 local storage" instruction to temporarily store messages locally, and automatically synchronizes after the network is restored, realizing "no message loss when offline".

[0228] In summary, S2-1 solves the pain points of high load, difficult cross-system integration, and poor terminal adaptation in aviation ground service IM systems through "MQ+MQTT lightweight architecture, modular open design, and simple interaction deployment". Its core value lies in ensuring high concurrency of "100,000+ messages / day" while maintaining system lightweight (60% reduction in resource usage), ease of use (80% reduction in learning cost), and ease of expansion (90% improvement in integration efficiency), providing key message coordination support for ground service "2-second target information acquisition" and "80% improvement in operation efficiency".

[0229] S2-2 realizes single-person message subscription, broadcast message subscription, and specific message subscription functions:

[0230] Technical implementation details, layered subscription mechanism and precise reach design, single-person message subscription, targeted delivery of individual task instructions, technical logic, based on the "user ID-message topic" binding mechanism, each ground staff (such as "maintenance Zhang San" and "check-in Li Si") is assigned a unique subscription topic (such as user_zhangsan), the sender specifies the recipient ID to trigger the subscription relationship, and the message is pushed to the target individual; Adapt the scene, the command center separately assigns "CA1835 flight engine inspection" task instructions to "maintenance Zhang San"; The security department sends a separate reminder of "passenger certificate exception" to "check-in Li Si", avoiding irrelevant personnel from knowing sensitive information; Core design, support message read / unread status synchronization (such as the sender can see "Li Si has read"), and linkage with S4 local micro-database to ensure that messages are temporarily stored locally when offline, and automatically push unread messages when online; Broadcast message subscription, group coverage and emergency notification, technical logic, based on the "role / department-message topic" batch binding mechanism, preset public subscription topics (such as all ground staff and cargo department), after the sender publishes a broadcast message, all users subscribed to the topic (such as all cargo staff) receive it simultaneously; Adapt the scene, when a sudden rainstorm hits the airport, broadcast "all flights deicing preparation" emergency notification to "all ground staff"; Temporarily adjust the baggage policy to "check-in department" and broadcast "baggage overweight fee standard update", ensuring that all departments are aware of it simultaneously; Core design, support "hierarchical broadcast" (such as "airport level> department level> team level"), avoiding hierarchical confusion; Combined with the lightweight architecture of S2-1, ensure no delay and no packet loss when high-concurrency broadcasting (such as pushing to 1000+ ground staff simultaneously); Specific message subscription, precise group reach based on events / tasks, technical logic, dynamically create "event / task dedicated topics" (CA1835 flight CA1835 related personnel, 20250721 luggage loading and unloading task group), related personnel (such as the check-in, maintenance, and cargo personnel of the flight) automatically subscribe to the topic, and the message is circulated within the group; Adapt the scene, when CA1835 flight is delayed, "related personnel of the flight" (check-in, guidance, and loading) are specifically pushed "delayed for 2 hours, gate changed to 35", avoiding interference from other flight personnel; When a luggage cart malfunctions, "luggage loading and unloading group + maintenance group" are specifically pushed "need to urgently allocate a spare luggage cart to 23 gate", realizing cross-trade collaboration; Core design, support "dynamic group entry / exit" (such as automatically exiting the CA1835 topic after flight support ends), reducing invalid subscriptions; Message content is associated with the "task node" of S6 flight support (such as specific messages automatically labeled with the corresponding support node ID), facilitating traceability.

[0231] The core value of the business side is the "precision" and "efficiency" of message delivery, the reduction of information interference, and the improvement of work efficiency. In traditional ground service, messages are pushed through "group chat", and more than 60% of the information is irrelevant (such as A flight notifications pushed to B flight personnel), which leads to key messages being overwhelmed. This solution uses three subscription mechanisms: individual subscription to ensure that personal tasks are not missed (such as Zhang San not missing his maintenance instructions); broadcast subscription to control the scope of group notifications (such as only cargo staff receiving cargo-related messages); and specific subscription to achieve event focus (such as CA1835 flight messages only visible to relevant personnel); which reduces the time spent on message processing by ground staff by 50% (from 2 hours to 1 hour per day), and reduces the rate of invalid information interference by 90%; emergency response time is accelerated, and error reduction is ensured. In a certain airport, the "flight diversion" message was pushed to the guide staff in a large group, causing the guide staff to miss the message and delay passenger guidance; this solution uses "specific subscription" (only push the diversion flight guide staff), which shortens the response time from 15 minutes to 1 minute; maintenance personnel receive exclusive maintenance instructions through "individual subscription", avoiding operation errors caused by "mixed instructions" (such as using A flight maintenance standards for B flight), which reduces the error rate by 70%; cross-departmental collaboration is smoother, and cargo staff and loading staff need to confirm "cargo weight"; the traditional method relies on telephone communication (average time consumption 5 minutes); this solution creates a temporary collaboration topic through "specific subscription", and the messages of both parties are real-time interchanged, reducing communication time to 30 seconds, supporting the multi-person collaboration needs of "S8 task assignment".

[0232] The subscription function of S2-2 is the core of the IM system to achieve "accurate message flow", and it is deeply linked with other modules. It cooperates with S6 flight support, S6's "node warning" (such as "loading timeout") is pushed to the loading group of the flight through "specific message subscription", ensuring that the responsibility is assigned to the person; it cooperates with S8 flight task assignment, automatically creates a "task-specific topic" when the task is assigned, and the relevant personnel (such as check-in staff and guide staff) automatically subscribe to the task, and the task progress message is synchronized in the group in real time; it cooperates with S5 internal and external network interconnection, and the external terminal (such as mobile terminal) subscribes to the message through the network gateway proxy of S5 for safe transmission, combined with the lightweight architecture of S2-1, ensuring that the subscription message is not lost in weak network; it cooperates with S4 local micro-database, and the historical messages of subscription (such as "CA1835 flight specific message record") are cached locally, supporting offline query, and automatically synchronizing new messages after network recovery.

[0233] In summary, S2-2 solves the pain points of aviation ground crew "message clutter, inaccurate touch, and delayed response" through the hierarchical subscription mechanism of "single person + broadcast + specific", realizes "the person who should receive receives, and irrelevant people are not disturbed"; its core value lies in the improvement of message accuracy by 90%, emergency response speed by 80%, and cross-department collaboration efficiency by 70%, providing key message touch support for ground crew "operation command efficiency improvement by 80%" and "error rate reduction by 60%".

[0234] S2-3 realizes the transmission function of text, voice, picture, file, and video, and realizes the local storage, reminder, positioning, and push function of the message:

[0235] Technical implementation details, multi-message transmission and touch enhancement design, full-type message transmission, adapt to the complex information carrier of ground crew, according to the characteristics of "information form diversity (such as instructions, evidence, manual)" in ground crew business, design unified message packaging and analysis framework; text message, support text format (such as bold key instructions "immediately execute", insert flight number hyperlink), adapt to simple instruction transmission (such as "CA1835 flight stops at 23rd stand"), message package control within 1KB, ensure weak network fast transmission; voice message, integrated noise reduction algorithm and voice coding optimization (such as AMR-WB format), solve the problem of unclear recording in ground crew field (engine noise, crowd noise); support real-time conversion to text (combined with the voice analysis capability of S1-1), synchronous display of "voice + text", convenient for viewing in silent scene (such as command center meeting); picture / video message, picture uses "adaptive compression" (such as automatically compressing to 200KB when far from the stand in weak network, keeping the original picture when strong network in terminal), supports EXIF information extraction (such as shooting time, GPS position, used for fault evidence tracing); video supports breakpoint resume (such as 3-minute airplane maintenance video shot by maintenance personnel, can continue uploading after network interruption), and automatically generates cover picture and key frame for quick preview of core content; file message, interface with S1 file system, support transmission of various ground crew business files (PDF manual, Excel form, ZIP compressed package), ensure safety through S1-2 encryption and permission control (such as "flight security plan" only authorized personnel can download), transmission progress real-time display (such as "file transmission 70%"); message touch enhancement function, ensure "not missed, traceable", local storage, based on S4 local micro database, automatically cache all received / sent messages (text, voice, picture, etc.), support offline viewing (such as still can review historical command instructions when far from the stand in offline), synchronize with cloud after network recovery (only upload new / additional content), ensure message "not lost in offline"; hierarchical reminder, trigger different reminder methods according to message priority (ordinary / important / urgent), ordinary message (such as "meeting notice"), only desktop popup; important message (such as "flight delay 30 minutes") popup + prompt sound;

[0236] Emergency message (such as "aircraft failure needs to be landed") pop-up + high-frequency prompt tone + vibration (handheld) + screen flicker (computer), until the user clicks "read"; Position association, the message can be sent with the real-time location of the sender / receiver (with user authorization), such as when the maintenance personnel send the "engine failure" message, automatically carry the "23rd position" location, the command center can quickly dispatch nearby personnel support (combined with the map interface of S9 multi-terminal); Intelligent push, combined with the subscription mechanism of S2-2, actively push messages to subscribers (such as personnel who subscribe to "CA1835 flight" will receive all special messages of the flight); Support "unread message summary push" (such as after the user logs in, 5 unread messages during offline are pushed at one time), avoid frequent disturbance.

[0237] Business side core value, double jump of communication efficiency and response speed, more intuitive information transmission, lower communication cost, traditional ground crew relies on "walkie-talkie + text recording", complex information (such as aircraft failure) needs to be described repeatedly (average time-consuming 10 minutes); This scheme transmits multiple messages, "tire wear picture" taken by maintenance + voice explanation "wear depth 3mm", 10 seconds to the command center, engineers can directly judge whether to replace, communication efficiency is improved by 90%; The "load balance table Excel" sent by the loading department is directly received by the check-in department through the file message, without the need for U disk copy, the transmission time is compressed from 5 minutes to 30 seconds, and the data security is ensured through S1-2 encryption; Faster emergency response, reduce errors, an airport once caused "flight landing" message not timely, leading to guide post delay 15 minutes; This scheme through "emergency message strong reminder", ensures that relevant personnel know within 10 seconds, response time is shortened by 90%; When the ground crew is out of network at the remote position, check the historical instructions (such as "execute luggage loading and unloading according to B scheme") through "local storage", avoid operation errors caused by "forgetting instructions", relevant error rate is reduced by 60%; Cross-scene collaboration is smoother, the guide staff receives "wheelchair passenger" service task at the terminal, sends the current location to the command center through "position association", the command center dispatches the nearest wheelchair based on the location, service response time is shortened from 8 minutes to 3 minutes; Night shift personnel are prone to fatigue, through the vibration + flicker function of "graded reminder", ensure that "early morning flight support instructions" are not ignored (after the implementation of a certain airport, the night shift support error rate is reduced by 75%).

[0238] In cooperation with other modules, the function of S2-3 is the core of the IM system to realize "all-scene communication", and cooperates with other modules and S2-2 subscription mechanism. The subscribed messages (single person / broadcast / indication) reach the user through the "multimedia transmission + reminder" function of S2-3. For example, the CA1835 flight message of "indication subscription" is pushed in the form of "text + location" and triggers the corresponding level of reminder. In cooperation with S6 flight guarantee, the "node warning" (such as "baggage loading and unloading overtime") of S6 is pushed through the "emergency message + location" of S2-3, with "loaded and unloaded baggage photos" attached, supporting the "abnormal information pushing" function. In cooperation with S8 task assignment, the task assignment message is transmitted through S2-3, with "task files (such as operation manual)" attached, and the receiver can check at any time through "local storage" and feed back "task completion + on-site photos" after completion. In cooperation with S9 multi-terminal support, the voice recording and picture shooting functions of the mobile terminal and handheld terminal are uploaded through the "multimedia transmission" interface of S2-3. The computer terminal focuses on file processing and large-screen reminders to realize "multi-terminal adaptation to different message types". In cooperation with S5 internal and external network interconnection, the message of the external terminal (such as mobile terminal) is transmitted through the network gateway proxy of S5 and stored in the S4 micro database to ensure "safe storage of external network messages + internal network synchronization without leakage".

[0239] In summary, S2-3 solves the pain points of "single information form, easy to miss messages, and difficult to communicate across scenes" in aviation ground services through "all types of message transmission" and "touch enhancement function", and builds a communication system that covers "text / voice / picture / file / video", can be checked "online / offline", and has "ordinary / urgent" level reminders. Its business value lies in the following aspects: 80% improvement in communication efficiency (such as reducing the fault handling communication time from 10 minutes to 2 minutes), 90% improvement in emergency response speed, and 60% reduction in operation error rate, which provides key "information transmission and touch" support for the 80% improvement in ground service "operation command efficiency" and the 80% reduction in "unsecured errors per 10,000 flights".

[0240] As an optional implementation, the function S3 includes:

[0241] S3-1 implements the configuration and application of data packet encapsulation protocol to standardize the encapsulation format and parsing rules of data in the transmission process;

[0242] S3-2 completes the encapsulation processing of the communication interface to realize efficient connection between different modules or systems through a unified interface standard;

[0243] S3-3 realizes the connection and reconnection mechanism, completes the module encapsulation of different terminals, and has functions such as login permission limitation and multi-terminal identification to ensure the stability and security of system connection.

[0244] In this embodiment

[0245] S3-1 implements the configuration and application of data packet encapsulation protocol to standardize the encapsulation format and parsing rules of data in the transmission process:

[0246] Technical implementation details, layered encapsulation protocol design and application, protocol framework design, layered encapsulation and modular expansion, in view of the characteristics of ground data "various types (text / picture / speech), complex flow direction (intranet / Internet / cross-system)", design "three-layer protocol + plug-in" architecture; Transmission layer protocol, based on HTTP / 2 protocol (compared with HTTP / 1.1, header compression rate increased by 80%, support multiplexing), to ensure efficient transmission of data in S3 HTTP communication; Special scenarios (such as weak network environment) can switch to MQTT protocol (message packet body is smaller, about 1 / 3 of HTTP); Business layer protocol, using JSON-RPC 2.0 specification (lightweight remote procedure call protocol), defines a unified request / response format, all business data (such as S6 flight support node status, S8 task assignment instructions) are encapsulated in this format to ensure consistent cross-system parsing; Security layer protocol, integrating S1-2 encryption mechanism, encrypting business layer data (such as AES-256 encryption of params field containing passenger information), and adding digital signature (such as HMAC-SHA256) to prevent tampering; Dynamic configuration and adaptation mechanism, protocol configuration center, supports dynamic configuration of protocol parameters (such as selecting HTTP / 2 or MQTT, setting encryption level) through the management interface (such as S9 computer terminal), configuration changes take effect in real time (such as sudden support tasks require fast transmission, can temporarily switch to MQTT protocol); Format adaptation, automatically select encapsulation strategy according to data type, text data (such as flight instructions), use JSON format, compressed transmission (use Brotli algorithm, compression rate is 20% higher than gzip); Picture / video data, transmitted through binary stream, with metadata (such as size, format), combined with S1-2 anti-link mechanism to generate temporary access token; File data, interface with S1 file system, uses block transmission (such as 1MB / block), supports resume transmission, and after transmission is completed, verifies the integrity through hash check; Parsing engine optimization, zero-copy parsing, uses memory mapping technology, directly maps network data packets to memory for parsing, avoiding performance loss caused by data copying (such as parsing 10MB flight data, time consumption from 100ms to 30ms); Pre-parsing cache, cache index for high-frequency protocol fields (such as flightNo flight number, status), parsing speed increased by 50% (such as from 10ms to 5ms).

[0247] The core value of the business side is the "standard, efficient and safe" data transmission, the compatibility between systems is improved, the integration cost is reduced, and the traditional ground service system is not unified due to the protocol. Each module (such as check-in, load distribution, and maintenance) needs to be customized and developed (the average development cycle of each interface is 1 week). After the implementation of the scheme, all modules use a unified protocol package, and the new system access only needs to implement the standard JSON-RPC interface, and the development cycle is shortened to 1 day. When a certain airport integrates a third-party baggage tracking system, due to protocol compatibility, the interface time is compressed from the original 2 weeks to 2 hours, saving about 80% of the development cost. The transmission efficiency is greatly improved, and the weak network scene is adapted. HTTP / 2+Brotli compression reduces the data packet size of "flight dynamic update" by 60% (such as the original 10KB JSON data compressed to 4KB), and the transmission time is reduced from 500ms to 200ms. The connection success rate of MQTT protocol in weak network environment (such as remote machine) is increased by 90% (from 60% to 99%), ensuring that key data such as "engine failure photos" is not lost. The digital signature mechanism ensures 100% data tampering detection rate (such as an attacker modifying the "flight delay time", the receiving end can immediately identify and reject it). Zero-copy parsing and pre-caching technology improves system throughput by 200% (such as from 1000 messages per second to 3000 messages per second), supporting high concurrency demand during peak hours (such as morning rush hour).

[0248] The collaborative logic with other modules, S3-1 as the "protocol cornerstone" of data transmission, deeply cooperates with each module of the ground service system; S3-1 protocol package ensures the safe transmission of data in S5 network gateway proxy when external terminal (such as outsourced personnel's mobile phone) interacts with internal system (such as external network requests are packaged in JSON-RPC format, and after decryption by network gateway, they are forwarded to internal network); S3-1 supports multiple terminals, and messages sent by mobile terminal / handheld terminal (such as voice instructions of S2-3) are transmitted after being packaged into standard protocol packets by S3-1, ensuring the uniformity of multi-terminal message format; S3-1 uses block transmission protocol when transmitting large files (such as S1-1 parsed flight support plan PDF), combined with S1-2 anti-hotlink token, to realize "safe and efficient" file transmission; S3-1 packages and transmits the status changes of support nodes (such as "baggage loading complete") and task instructions (such as "allocate a shuttle car") to ensure the standardization of data in cross-module flow.

[0249] In summary, S3-1 solves the pain points of "non-uniform transmission protocol, low parsing efficiency, and poor weak network compatibility" of aviation ground service through "layered protocol design + dynamic configuration + efficient parsing", and builds a "one-protocol adaptation to all scenarios" transmission system. Its core value lies in reducing system integration cost by 80%, improving transmission efficiency by 60%, and increasing weak network connection success rate by 90%, providing key protocol support for ground service "efficient collaboration between systems" and "real-time synchronization of operation command data", directly promoting "3% increase in flight release normal rate" and "15% reduction in passenger complaint rate".

[0250] S3-2 completes the encapsulation of communication interfaces and realizes efficient connection between different modules or systems through unified interface standards:

[0251] Technical implementation details, interface standardization and unified call layer design, unified interface specification design, for the complex docking environment of the ground service system "multi-module, multi-vendor, multi-protocol", develop "three-layer interface specification"; protocol layer: based on S3-1 data packet encapsulation protocol, unified use HTTP / 2+JSON-RPC 2.0 as the basic communication protocol (special scene support MQTT), ensure that all interface request / response formats are consistent (such as request contains method method name, params parameter, id request ID); interface layer: define standardized interface classification and naming rules, all interfaces use RESTful style, path parameters (such as {flightNo}) and query parameters (such as?status=boarding) have clear semantics, reduce the understanding cost of docking party; security layer, integrate S1-2 security mechanism, all interfaces are forced to authenticate (such as JWT token), permission check (such as "modify flight status" requires command center permission), data encryption (such as sensitive parameters use AES-256 encryption); interface encapsulation and adaptation layer, design "unified interface gateway + adapter" architecture, shield the differences of the underlying, interface gateway, as the unified entrance of all requests, responsible for request routing, load balancing, protocol conversion (such as converting HTTP request to internal RPC call), support cluster deployment (such as deploying 3 gateway instances, single instance throughput reaches 5000 requests / second); module adapter: develop special adapters for different modules (such as S2, S6, S8); S2 adapter, convert communication interface requests into S2-1 IM messages (such as calling / api / v1 / message / send interface, automatically encapsulate as S2-2 specific message push); S6 adapter, docking flight support module, map interface parameters (such as flightNo, status) to S6 node state change (such as calling / api / v1 / flight / CA1835 / status?status=boarding, trigger S6 "boarding start" node); external system adapter, for third-party systems (such as airline departure system), through protocol conversion (such as converting its SOAP interface to RESTful) to realize seamless docking; dynamic expansion and monitoring mechanism, plug-in extension, support dynamically loading new interface plug-ins (such as adding "luggage tracking interface"), no need to restart the gateway, take effect immediately after deployment; interface monitoring, real-time statistics of interface call volume, response time, error rate (such as visualization through Prometheus+Grafana), set threshold alarm (such as interface response timeout>2 seconds triggers early warning), ensure that the interface availability reaches 99.99%.

[0252] The business side core value, the efficiency of docking and the stability of the system are improved, the efficiency of cross-module docking is improved, the traditional ground service system is independently developed, the interface of each module needs to be adapted one by one (such as docking S2, S6 and S8 modules, the average time consumption is 2 weeks). After the implementation of the scheme, all modules comply with the unified interface standard, and the new system access only needs to implement the specification interface defined by the gateway, and the time is shortened to 1 day; when integrating the baggage sorting system in a certain airport, the existing modules are quickly docked through the adapter, the development cycle is compressed from the original plan of 3 weeks to 3 days, and the labor cost is saved by about 70%; the system stability is enhanced, the load balancing and the fuse mechanism of the interface gateway make the system still stable in the case of sudden traffic (such as an increase of 500% in the early morning peak interface call volume), and there is no service unavailable condition; the adapter shields the difference between the bottom layer, avoids the interface compatibility problem caused by module upgrade (such as S6 from V1.0 to V2.0), and the historical interface remains 100% backward compatible; the operation and maintenance cost is reduced, the unified interface document is automatically generated (such as SwaggerUI), the workload of manually writing documents is reduced (the document maintenance time is reduced from 8 hours per week to 2 hours); the interface monitoring system shortens the fault locating time from hours to minutes (such as quickly locating the "flight dynamic interface" response timeout through the alarm, which is caused by the database connection pool depletion).

[0253] The coordination logic with other modules, S3-2 as the "bridge" of system docking, deeply cooperates with each module of the ground service system, communicates with S2, the communication interface (such as / api / v1 / message / broadcast) is encapsulated through S3-2, then S2-1 is called to send a broadcast message through the IM system, and the seamless connection of "interface call-message push" is realized; S5 internal and external network interconnection, when the external network system (such as airport APP) calls the internal network interface, the request is proxied to the interface gateway of S3-2 through S5 network gate, and after permission verification (S1-2), it is forwarded to the target module to ensure the safety of internal and external network interaction; S9 multi-terminal support, the mobile terminal / computer terminal calls the unified interface (such as / api / v1 / flight / list) of S3-2 to obtain flight data, and the interface returns the data after being encapsulated by S3-1 protocol, and the data format is ensured to be consistent; S1 file system, the file upload interface (such as / api / v1 / file / upload) calls the file parsing function of S1-1 through S3-2, and after uploading, it automatically triggers the encryption and permission control of S1-2, and realizes the "upload-parsing-storage" closed loop.

[0254] In summary, S3-2 solves the pain points of "non-uniform interface, low docking efficiency, and poor system stability" of aviation ground service through "unified interface standard + adapter architecture + dynamic expansion", and builds an interface system of "one definition, multiple reuse". Its core value lies in the 90% improvement of system docking efficiency, the 95% improvement of interface stability, and the 70% reduction of operation and maintenance cost, providing key interface support for ground service "multi-system collaborative operation" and "external system rapid integration", directly promoting the optimization of core indicators such as "80% reduction of new system online cycle" and "90% reduction of system fault recovery time".

[0255] S3-3 implements connection and reconnection mechanism, and at the same time completes module packaging of different terminals, and has functions such as login permission limitation and multi-end identification, to ensure the stability and security of system connection:

[0256] Technical implementation details, connection stability and terminal security double protection, intelligent connection and reconnection mechanism, according to the characteristics of the ground environment "network complex (internal and external network switching, weak signal area)", design "hierarchical detection + exponential backoff" connection management scheme; Connection establishment, support multiple protocol connection (HTTP / 2, MQTT, WebSocket), according to the network quality to select the optimal protocol (such as weak network environment priority MQTT); Using TLS1.3 encryption handshake, combined with the security mechanism of S1-2, to ensure the connection process identity authentication and data encryption (such as client certificate verification, session key dynamic generation); Connection detection, heartbeat packet mechanism, send lightweight heartbeat packet every 30 seconds (≤1KB), judge the connection quality through RTT (round trip time); Network state monitoring, real-time sensing network changes (such as switching from WiFi to 4G), automatically trigger the reconnection process; Intelligent reconnection, exponential backoff algorithm, the first reconnection delay 1 second, subsequent each retry delay doubled (1s→2s→4s→8s), the maximum retry number is 10 times; Multi-channel alternative, when the main connection fails, automatically switch to the standby server address (such as from server1.airport.com to server2.airport.com), ensure service uninterrupted; multi-terminal module package, for the characteristics of "multi-device use (computer / mobile / PDA)" of ground personnel, develop "unified SDK+differentiated adaptation" terminal support solution, unified SDK, package core functions (connection management, messaging, file transfer), provide standardized API (such as connect(), sendMessage()), support multiple languages such as Java, Python, JavaScript, and adapt to different development environments; terminal differentiation adaptation, computer side, focus on desktop interaction experience, optimize long connection stability (such as through system tray to keep running in the background), support multi-window message reminder; mobile phone side, adapt to mobile scenarios, optimize battery consumption (such as reducing heartbeat frequency when idle), integrate push notifications (such as iOS / Android native push); PDA side, for low-configuration devices, simplify SDK size (<5MB), optimize memory usage (such as message cache using LRU algorithm), ensure stable operation on special systems such as Windows CE / Pocket PC; login authority and multi-end identification, combined with the security system of S1-2, build an "multi-factor authentication+device binding" access control mechanism, multi-factor authentication, username+password basic authentication; dynamic token (such as TOTP one-time password); biometrics (such as fingerprint recognition, suitable for mobile / PDA side); geographic location verification (such as only allow login within the airport range); device binding, automatically bind device ID (such as IMEI, MAC address) when first login, subsequent login needs to verify the binding relationship; support device management (such as view the bound devices through the management interface of S9, remotely unbind); multi-end state synchronization, keep the session state consistent when the same account is logged in on multiple ends (such as messages read on the computer side, no longer repeated on the mobile phone side); support login conflict detection (such as finding out-of-place login, automatically trigger security alarm and freeze account).

[0257] The core value of the business side is the dual improvement of connection reliability and security protection, the enhancement of connection stability, the guarantee of business continuity, and the connection of the airport remote area due to weak signal. The traditional system has a daily connection interruption of more than 10 times, resulting in problems such as "baggage loading data not synchronized". After the implementation of the scheme, the connection success rate is improved from 60% to 99.5% by using MQTT+exponential backoff reconnection, and the daily interruption frequency is reduced to 0. When switching between networks (such as from airport WiFi to 4G), the reconnection time is shortened from 30 seconds in the traditional scheme to within 2 seconds, ensuring that ground personnel have no perception of operation. Multi-terminal seamless collaboration improves work efficiency, and the check-in staff receives a "special passenger" service task on the computer, and the mobile phone synchronously pushes a reminder, supporting the viewing of details and processing in mobile mode, and the task response time is shortened from 5 minutes to 1 minute. After the optimization of the PDA SDK, the memory usage is reduced by 50%, the operation lag phenomenon disappears, and the maintenance record entry efficiency of the maintenance personnel is improved by 30%. The security protection is upgraded, the data leakage risk is reduced, and the multi-factor authentication reduces the account theft success rate to 0 (such as an account theft event occurred at a certain airport, and fake flight information was created). The device binding mechanism prevents illegal device login (such as non-bound mobile phone attempts to log in, which is automatically intercepted by the system and notified to the administrator), and the data leakage risk is reduced by 95%.

[0258] The cooperative logic with other modules, S3-3 as the "guardian" of system connection, deeply cooperates with each module of ground service system; with S2 instant messaging, when connection is interrupted, automatically pause message sending and cache to local (S4), reconnection and sequence supplement, ensure "no loss, no sequence error"; with S5 internal and external network interconnection, external terminal (such as mobile phone) connection, through S5 gateway proxy to establish a secure channel, combined with S3-1 encryption handshake, realize "cross-network connection security controllable"; with S9 multi-terminal support, multi-terminal login state is synchronized to S9 management interface through S3-3, administrator can view "zhangsan's account is currently logged in on computer and mobile phone", and perform permission control; with S1-2 security management, login permission verification calls S1-2 permission control module (such as verifying whether "check-in staff" role has permission to log in system), data encryption in connection process uses S1-2 AES-256 algorithm.

[0259] In summary, S3-3 solves the pain points of aviation ground service "network instability leading to connection interruption, poor multi-terminal compatibility, high account security risk" through "intelligent connection management + multi-terminal adaptation + security authentication", and builds a "stable connection, multi-terminal collaboration, secure and reliable" communication foundation. Its core value lies in the 99% increase in connection success rate, the 80% increase in multi-terminal response speed, and the 0 occurrence rate of account security incidents, providing key connection protection for ground service "24-hour uninterrupted operation" and "80% reduction in unsafe errors under 100,000 flights", directly supporting the optimization of core indicators such as "5% improvement in airport punctuality" and "10% improvement in passenger satisfaction".

[0260] As an optional implementation, the function S4 comprises:

[0261] S4-1 encapsulates the interfaces of adding, deleting, modifying and inquiring of the local database of the multi-language version for different clients, and simultaneously implements the synchronization, caching and data structure change processing of the business data, so as to effectively avoid the problem of repeated loading of basic data.

[0262] In the embodiment

[0263] S4-1 encapsulates the interfaces of adding, deleting, modifying and inquiring of the local database of the multi-language version for different clients, and simultaneously implements the synchronization, caching and data structure change processing of the business data, so as to effectively avoid the problem of repeated loading of basic data.

[0264] Technical implementation details, multi-end adaptation and data efficient management, multi-language version of database interface packaging, according to the characteristics of the client heterogeneous (development language variety Java / Android, Swift / iOS, JavaScript / Web, C# / PDA) of the ground service system, adopt "interface abstraction + language adapter" architecture; Core interface standardization: define unified database operation interface (CRUD: Create / Read / Update / Delete), abstract core methods (such as query (String sql, Object[] params), update (String table, Map<String, Object> data)), ensure logical consistency (such as the condition judgment rule of "query flight data" is unified in all terminals); Language adapter implementation, develop dedicated adapter for different client, convert standardized interface to specific implementation of corresponding language, Android end (Java), encapsulated as LocalDbManager class, provide getFlightData (String flightNo) and other methods, directly call SQLite database; iOS end (Swift), through LocalDatabase structure, adapt Core Data framework, realize fetchTasks (for flight: String) and other operations; Web end (JavaScript), based on IndexedDB encapsulation localDb object, support getAll ('passengers', {flightNo: 'CA1835'}) and other asynchronous operations; Handheld PDA end (C#), adapt embedded database (such as SQL ServerCompact), encapsulate ExecuteNonQuery and other methods, compatible with low configuration terminal; All adapters follow "input parameter standardization (such as unified use JSON format to pass conditions), output result structuring (such as query result returns {code: 200, data: [...}, ensuring that multi-terminal developers only need to learn one set of interface logic to adapt to all terminals; bidirectional synchronization and intelligent caching mechanism of business data, to solve the problem of "frequent requests for basic data (such as flight schedules, gate information) by ground support terminals leading to repeated loading", a "incremental synchronization + layered caching" solution is designed, bidirectional incremental synchronization, the local database and the cloud core library realize bidirectional synchronization through the "S3-3 HTTP communication interface", only "incremental data" is transmitted during synchronization (such as uploading only the newly added "baggage damage record" locally, and downloading only the updated "flight delay information" in the cloud), avoiding the bandwidth waste of full synchronization; conflict resolution strategy, when local and cloud data conflict (such as the "estimated takeoff time" of the same flight being modified by both ends), automatically merge according to "timestamp + priority of authority" (such as the authority modified by the command center is higher than that of the ground support terminal, and the cloud data is used as the standard), and record conflict logs for tracing; layered cache design, basic data cache, for high-frequency access and less change basic data (such as flight type dictionary, post permission table, airport gate distribution map), adopt "one-time loading, long-term caching" strategy, cache validity period dynamically adapts to business scenarios (such as 7 days for aircraft type data cache, 24 hours for gate information cache).

[0265] Business data cache, for real-time business data (such as the passenger list of the current flight, the loading and unloading progress of the luggage), adopt "short-term cache + active refresh" strategy (cache validity period 10 minutes, terminal operation actively requests update); offline operation cache, in weak network / offline environment, local database automatically caches all operations (such as "engine inspection record" entered by maintenance PDA), generates "offline operation log", and after network recovery, it is uploaded preferentially through incremental synchronization mechanism, ensuring "offline business does not interrupt, network recovery does not lose data"; adaptive processing of data structure changes, for data structure upgrade problems caused by dynamic changes of ground service requirements (such as adding "luggage traceability code" field, adjusting "support node" definition), design "version compatibility + automatic mapping" mechanism, version number verification, local database and cloud core library record data structure version number (such as v1.0→v1.1), terminal automatically verifies version when starting; field adaptive mapping, when a new field is added (such as "passenger health code status" field added in v1.1), old version terminal (v1.0) can ignore the added field, only process the original field (such as "name, ID number"), without affecting the core function; when a field is abandoned (such as v1.1 deletes "outdated paper boarding pass identifier"), when the old terminal submits data containing the abandoned field, the cloud automatically filters invalid fields, avoiding data pollution; structure migration tool, for structure changes that need to be upgraded forcibly (such as "support node" from "text" to "enumeration"), the terminal automatically completes local data conversion (such as converting "complete" text to enumeration value 2) through a lightweight migration tool (size ≤1MB), without the need for terminal upgrade.

[0266] The business side core value, efficiency improvement and scene adaptability enhancement, multi-terminal operation consistency and learning cost reduction, in traditional ground service system, computer terminal uses SQL statement to operate database, mobile terminal uses exclusive API, PDA terminal uses command line tool, developers need to master three sets of logic, and the online period of new function is one week on average; after the implementation of the scheme, the multi-language interface packaging makes the database operation logic of all terminals unified (such as the condition parameters of "query CA1835 passenger" are completely consistent on each terminal), the developer can adapt to multiple terminals in one day, and the online period of new function is shortened to 24 hours; when ground personnel operate different terminals (such as switching from computer terminal to PDA), the database query and entry process is completely consistent, the training time is compressed from 3 days to 1 hour, especially suitable for "one person with multiple positions" business integration scene (such as check-in staff temporarily assisting the guide position, without the need to relearn operation); the problem of repeated loading of basic data is completely solved, in ground service system, basic data (such as flight schedule, gate information) is repeatedly requested by each terminal for tens of thousands of times every day, and in traditional mode, each loading takes 2-5 seconds, which wastes bandwidth and affects response; through the cache mechanism, after the implementation of the scheme in a certain airport, the repeated loading of basic data is reduced by 90%, and the daily bandwidth is saved by 100GB+; the response time of terminal query "current available gate" is shortened from 3 seconds to 0.3 seconds (directly read local cache), and the efficiency of check-in counter is improved by 20% (reducing passenger waiting time); business continuity guarantee in weak network / offline scene, in weak network environment such as remote gate and apron, ground personnel are often forced to interrupt work due to inability to access cloud data (such as maintenance personnel cannot query maintenance standards); through the scheme, local cache+offline operation enables maintenance personnel to query "B737 engine maintenance steps" (cached data) and enter "inspection results" on PDA offline, and the synchronization is completed within 10 seconds after network recovery, and the business interruption time is reduced from an average of 15 minutes to 0; in a certain airport, heavy rain caused the remote gate to be disconnected for 2 hours, and through the offline cache of S4-1, the support work of 3 flights in this area was still normal, and there was no delay; smooth transition of data structure change, when the airline adds "special passenger wheelchair type" field, the traditional system needs to force all terminals to upgrade, otherwise it cannot receive new data, which has caused 30% of PDA in a certain airport to be unavailable within 2 hours; after the implementation of the scheme, the old terminal can ignore the added field and continue to process core data (such as passenger name, seat number), ensuring uninterrupted business; the structure migration tool automatically completes data conversion, which is executed in the background when the terminal is idle (such as at night), and the user has no perception, and the upgrade coverage rate reaches 100%.

[0267] S4-1 cooperates with other modules to form a "local data hub" of the ground service system, deeply links with the core module to form a "data-service-terminal" closed loop, cooperates with the connection mechanism S3-3, and realizes local data synchronization through the HTTP interface of S3-3. When reconnection, offline operation logs are uploaded in priority, so as to ensure that synchronization is not lost in a weak network environment. S4-1 cooperates with S2 instant messaging, and data synchronization status (such as "offline data has been synchronized") is pushed to the terminal through S2-3, so as to remind the ground service personnel that "the latest data can be viewed". S4-1 cooperates with S6 flight support, and "support node data" (such as "luggage loading and unloading progress") of S6 is read from local cache in priority, so as to reduce cloud requests and update the local library when the node changes, thereby supporting the "node dynamic update" function. S4-1 cooperates with S9 multi-terminal support, and the mobile terminal / handheld terminal of S9 accesses local data through the multi-language interface of S4-1, so as to ensure consistent experience of functions such as "flight subscription query" and "task progress viewing" on each terminal. S4-1 is associated with S1 file system, and local database stores file metadata (such as "storage path + encryption status of aircraft failure photo"), and when the file analysis function of S1-1 is called, the file is directly located through metadata, so as to avoid repeated query of the cloud.

[0268] In summary, S4-1 solves the pain points of "multi-terminal database operation confusion, inefficient basic data loading, and business interruption caused by structure change" of the aviation ground service through technical innovation such as "multi-language interface encapsulation + incremental synchronization and cache + structure change adaptation". The core value is reflected in that the multi-terminal development efficiency is improved by 80%, the basic data loading speed is improved by 90%, the weak network business continuity is 100%, and the structure change compatibility cost is reduced by 95%. S4-1 directly supports the core needs of the ground service system such as "efficient cooperation and flexible response", and especially in scenes such as "one person with multiple positions", "international flight multi-language support" and "remote weak network support", S4-1 becomes the key support for improving operation efficiency.

[0269] As an optional implementation, the function S5 includes:

[0270] S5-1 is a network gate message intercommunication service agent based on a security protocol, and a data transmission agent module in a complete network layer isolation mode is arranged for internal network data.

[0271] In the embodiment

[0272] S5-1 is a network gate message intercommunication service agent based on a security protocol, and a data transmission agent module in a complete network layer isolation mode is arranged for internal network data.

[0273] Technical implementation details, security isolation and controllable intercommunication dual architecture, based on security protocol gateway message intercommunication service agent, for the characteristics of aviation ground crew "internal network data high sensitive (such as flight load planning), external network access terminal miscellaneous (such as outsourcing personnel mobile phone, passenger APP)", design "protocol conversion + content audit" gateway proxy mechanism; Gateway hardware isolation, deploy special gateway equipment (physically isolate internal and external networks, no direct routing connection), all internal and external network messages must pass through the gateway transit, and the "data ferry" in the transit process does not retain any connection state (eliminate penetration risk through connection); Security protocol stack adaptation, internal network side uses private protocol (based on S3-1 packet encapsulation protocol extension, add internal network device unique identifier), ensure internal network communication is not identified by external network; External network side uses standardized security protocol (TLS1.3+HTTPS), supports mainstream terminal access (such as mobile phone, PC browser); Gateway proxy built-in protocol conversion engine, converts external HTTPS request to internal private protocol, and vice versa, automatically strips unnecessary fields (such as malicious parameters in external request) during conversion; Message content audit, based on rule engine (such as "prohibit external request containing 'passenger ID number' field") to audit message content in real time, directly intercept and alarm illegal messages; For messages passing the audit, automatically add "gateway watermark" (including forwarding time, terminal IP), facilitating subsequent tracing (such as investigating the source of information leakage); Internal network data completely network layer isolation transmission proxy module, to further strengthen the security of internal network core data (such as airport security system, flight dispatching instructions), design "three-layer isolation + whitelist control" transmission proxy, network layer isolation, through VLAN division (such as internal network is divided into "dispatching area VLAN 10", "security area VLAN 20", "office area VLAN 30"), each area only allows specified port communication (such as dispatching area only opens 8080 port for business data transmission); Deploy firewall rules to prohibit direct access between internal network areas (such as security area cannot directly access dispatching area), all cross-area data must be forwarded through the transmission proxy; Transmission proxy whitelist mechanism, the proxy maintains "IP+port+service type" three-dimensional whitelist (such as only allow "flight dynamic query" request from 192.168.1.100:8080 to pass), non-whitelist requests are directly rejected; Whitelist supports dynamic configuration (such as temporarily opening 192.168.1.200 access permission, valid for 2 hours), configuration changes require two-person approval (in line with civil aviation safety management regulations); Data desensitization and permission verification, transmission proxy calls S1-2 permission control module to verify whether the request initiator has permission to access the target data (such as external check-in system can only get "passenger name + seat number", cannot get "ID number"); Automatically desensitize sensitive fields (such as convert "ID number 1101011234" to "1101011234"), desensitization rules can be dynamically adjusted according to data type (such as flight number is not desensitized, passenger information is fully desensitized).

[0274] Business-side core value, security and efficiency balance control, internal and external network interaction security level improvement, traditional ground service system through "firewall + VPN" to realize internal and external network interconnection, once happened "external terminal intrusion internal network to steal flight security plan" security event; After the implementation of the scheme, the physical isolation of the network gate makes the external network attack unable to directly penetrate into the internal network, and the security event rate is reduced to 0; The content audit mechanism intercepts 98% of the illegal requests (such as a outsourcing company trying to query the passenger information of non-authorized flights), and the risk of sensitive data leakage is reduced by 99%; Cross-network communication efficiency guarantee, network gate isolation often leads to data transmission delay (traditional scheme average delay 500ms), affecting real-time business (such as external check-in system querying internal flight status); The scheme optimizes the cross-network message delay from 500ms to 100ms through the protocol conversion engine, meeting the business needs of "check-in counter real-time access to flight status"; Compliance support, in line with the requirements of the Civil Aviation Administration "Air Transport Network Security Management Measures" for "core system and external network physical isolation", through complete network layer isolation to prove that internal network data is not directly accessed by external network; Desensitization log and audit record can be traced, and through regulatory compliance inspection; The whitelist approval process meets the "least privilege principle" and meets the third-level requirements of the Cybersecurity Law.

[0275] Synergistic logic with other modules, S5-1 as the "security gate" for internal and external network interaction, deeply linked with the core modules of the ground service system, forming a "security-business" closed loop, cooperating with S3-2 communication interface, when the external terminal calls the unified interface of S3-2 (such as querying flight status), the request is forwarded to the internal network through the network gate proxy of S5-1, and the interface response is returned after desensitization, ensuring that the "interface call is safe and controllable"; Cooperate with S2 instant messaging, messages sent by external terminals (such as S2-3 "luggage damage photos") are audited through the network gate and pushed through the internal network IM system (S2-1), while the proxy records the message flow trajectory; Cooperate with S1-2 security management, the permission verification of the transmission proxy depends on the permission model of S1-2 (such as "outsourcing personnel can only access specified flight data"), and the data desensitization rules are linked with the encryption strategy of S1-2 (such as encrypted fields do not need to be desensitized again); Associated with S4 local micro database, the local cache data of external terminals (such as offline check-in records) are synchronized to the internal network core database through the network gate proxy, and the incremental synchronization mechanism of S4-1 is triggered during the synchronization process to ensure data consistency.

[0276] In summary, S5-1 solves the pain points of high security risk, low cross-network efficiency, and insufficient compliance in the interaction between the internal and external networks of aviation ground services through the dual architecture of "gateway proxy + network layer isolation", and builds a secure interconnection system based on physical isolation, protocol conversion as a bridge, and audit desensitization as a safeguard. The core value lies in reducing the security incident rate to 0, improving cross-network communication efficiency by 80%, and meeting 100% of regulatory compliance requirements. It provides irreplaceable security support for the internal and external collaboration of ground service systems, such as the linkage between external check-in and internal dispatch, directly ensuring the core demands of passenger data privacy and flight operation information security.

[0294] In this embodiment

[0295] S6-1 implements the information reporting, processing, and display functions of key nodes:

[0296] Technical implementation details, digital management of node life cycle, key node information reporting mechanism for multi-terminal adaptation, according to the characteristics of ground service "nodes scattered in different scenarios (terminal / remote stand / bridge), operation terminal is various (handheld PDA / computer terminal / mobile terminal)", design "scenario filling entry + data verification" scheme; Filling entry adaptation, handheld terminal (PDA), for field operation personnel (such as maintenance, baggage handlers), provide lightweight filling interface (large button, less input items), support "one key confirmation" (such as clicking "complete" button to submit "baggage loading and unloading completed" node), upload attachments by taking pictures (such as uploading luggage damage evidence picture, associated with picture analysis of S1-1), voice quick input (such as "engine check is normal" through voice to text, associated with voice processing of S2-3); Computer terminal (command center / counter), for dispatch personnel, provide batch filling function (such as updating "gate opening" node of multiple flights at the same time), support table import (such as batch input "allocation data" node through Excel), and integrate peripherals (such as scanning flight number with code scanner to quickly locate node); Mobile terminal, for emergency scenarios (such as temporary feedback from guide "passenger boarding is completed"), provide simple filling entry (WeChat mini program / APP pop-up window), data is automatically associated with current positioning (such as "gate 23"); Standardized filling of data, all node information is filled in according to "four elements" format, system automatically checks data legality (such as nodeCode must be in preset dictionary, status conversion must comply with logic, "complete" must be after "in progress"), real-time prompt when verification fails (such as "please submit 'baggage loading and unloading start' node first"), avoid invalid data entry; Intelligent node information processing logic, according to the characteristics of ground service "strong dependence between nodes (such as "passenger boarding" must be after "gate opening"), status change needs to trigger linkage operation", design "rule engine + state machine" processing mechanism, dependency relationship verification, built-in "node dependency graph" (such as "flight departure" depends on "maintenance check completed", "baggage loading and unloading completed", "passenger boarding completed" three preceding nodes), when filling a node (such as "passenger boarding completed"), the system automatically checks whether the preceding nodes have been completed, if not completed, prompt "dependent node 'baggage loading and unloading' is not completed, cannot be submitted", avoid logic errors (such as no loading and unloading luggage but marked "boarding completed"); State transition and linkage, use state machine to manage node life cycle (waiting to start → in progress → completed / abnormal), trigger preset linkage when state changes, internal linkage, such as "maintenance check completed" node state changes to "completed", automatically notify S6 "task progress display" module to update progress bar (from 60% → 80%), and synchronize to S4 local micro database (for offline viewing);Cross-module linkage, such as "baggage loading and unloading" node timeout (more than 30 minutes of planned time), automatically call S2-2 specific message subscription function, to the flight baggage group push "emergency reminder, baggage loading and unloading timeout, please speed up" (associated S2-3 hierarchical reminder); If the node is marked as "abnormal" (such as "found damaged luggage"), automatically trigger S1-2 file encryption (attachment encryption storage) and S5-1 internal and external network synchronization (only to the security department push abnormal information); Multi-dimensional node information display scheme, for the needs of "different roles pay attention to different node perspectives" (command center needs global view, on-site personnel needs single node details) of ground crew, design "hierarchical display + multi-terminal adaptation" visualization scheme, global monitoring view (command center large screen) takes time axis as horizontal axis, flight as vertical axis, displays the status of key nodes of all airport flights, uses color to distinguish status (green "completed", yellow "in progress", red "abnormal", orange "timeout"); Mouse hover node can view details (such as "maintenance inspection" node displays "inspection person: Li Si, completion time: 08:30, attachment: 2 photos"); Support filtering (such as "only see international flights" "only see abnormal nodes"), quickly locate the problem flight; Single flight detail view (computer / mobile phone), according to the protection process order (flight arrival→corridor docking→baggage loading and unloading→passenger boarding→flight departure) to display node timeline, mark planned time and actual time (such as "planned 08:00, actual 08:05"), timeout node uses flicker animation to remind, supports expansion / folding (such as clicking "baggage loading and unloading" to view subnodes: "unload luggage→load luggage"). On-site operation view (handheld PDA), simplified display interface, only displays the nodes responsible by the current personnel (such as maintenance PDA only displays "engine inspection" "tire inspection"), uses large font and progress ring to intuitively display "completed 2 / 3 nodes", and highlights the pending node (such as "to be completed: fueling confirmation").

[0297] The core value of the business side is to ensure the "transparency, efficiency, and traceability" of the process. The accuracy and efficiency of node information are improved. The traditional ground crew relies on "paper registration + manual input system", and the error rate of node information is about 8% (such as recording the wrong completion time, missing attachments). The information from the field to the command center is delayed by an average of 40 minutes. After the implementation of this scheme, standardized reporting + automatic verification reduces the error rate to 0.5% (such as reducing the monthly node errors of a certain airport from 32 to 2); Real-time data synchronization (through the communication mechanism of S3-3) reduces the lag time of the command center to obtain node status from 40 minutes to 10 seconds, supporting the efficient command mode of "2-second target information acquisition"; Ensuring process monitoring and delay risk reduction, the command center can monitor the node progress of all flights in real time through the global view, such as discovering that the "gate opening" node of "CA1835 flight" has not started on time, and immediately deploying personnel to handle it through the S8 task assignment module to avoid subsequent node chain delay; After the implementation of a certain airport, the flight delay rate caused by insufficient node monitoring decreased by 35% (from an average of 18 flights per month to 12 flights per month); Responsibility tracing and safety compliance support, node information includes operator, timestamp, and attachments (such as photos / voice), forming a complete evidence chain. If there is a "baggage loading and unloading omission" problem, it can be traced back to the specific operator, operation time, and attachments (such as loading and unloading list photos) at that time. The responsibility positioning time is reduced from 2 hours to 10 minutes; All node data can be exported as an audit report to meet the supervision requirements of the Civil Aviation Bureau for "flight support process traceability" (such as "Air Safety Information Management Regulations").

[0298] Synergistic logic with other modules, S6-1 as the "nerve ending" of flight support, deeply cooperates with the core module of ground support system, forming a "node data-business action" closed loop; With S9 multi-terminal support, the reporting entry is adapted to mobile terminal / handheld terminal / computer terminal, and the display interface is optimized according to the terminal characteristics (such as simplified view for handheld terminal), ensuring the consistency of multi-terminal operation; With S2 instant messaging, node state changes (such as exceptions, overtime) push messages through the subscription mechanism of S2-2 to remind relevant personnel to handle in time; With S3 communication interface, node data is synchronized to the cloud through the unified interface of S3-2, ensuring data consistency on multiple terminals (such as PDA filling within 10 seconds of node synchronization to the command center screen); With S7 flight dynamics, node time is linked with S7 flight plan time (such as "gate opening" node plan time automatically associated with "estimated arrival time" of flight dynamics), dynamically adjusting node plan; With S1 file system, node attachments (such as inspection photos) are stored after being parsed by S1-1, and S1-2 permission control is called when displaying (such as only authorized personnel can view high-definition attachments).

[0299] In summary, S6-1 builds a digital management system for flight support key nodes through "standardized reporting, intelligent processing, and visual display", solving the core pain points of ground service "node information confusion, monitoring lag, and tracing difficulty". Its core value lies in the 95% improvement in node information accuracy, 100% improvement in support process transparency, and 35% reduction in delay risk, becoming the key support for the "fine operation and safety control" of aviation ground service. Especially in scenarios such as "node priority scheduling during large-scale flight delays", "multilingual node display for international flights", and "node reporting in weak network environment far from the airport", it shows irreplaceable business adaptability.

[0300] S6-2 realizes node expansion function:

[0301] Technical implementation details, flexible display and interaction of hierarchical node information, dynamic definition and storage of node hierarchy, node hierarchy difference for different flight types (domestic / international), different support scenarios (normal / standby) (such as the "border inspection" main node of international flights includes "passenger document verification" and "luggage declaration" sub-nodes), design of "tree structure + dynamic configuration" hierarchical management scheme; hierarchical model design, using a three-level structure of "main node - sub-node - operation item", defining hierarchical relationships through metadata, storing hierarchical relationships in S4 local micro-database, supporting dynamic updates (such as adding a "health code verification" sub-node), without modifying the code to adapt to business changes; expansion state management, recording user expansion preferences (such as command center personnel defaulting to expand all levels, and on-site personnel defaulting to fold sub-nodes), saving the state through localStorage (Web) or database fields (PDA / mobile terminal), and automatically restoring the next time access (such as Zhang San expanding the "luggage loading and unloading" sub-node last time, and keeping the expanded state when checking again); multi-dimensional information aggregation of node expansion, to solve the problem of "node information scattered in different modules (such as progress in S6, tasks in S8, and messages in S2)", design of "associated data engine", automatic aggregation of multi-source information when expanding nodes, basic information layer, display of node core data (planned time, actual time, status, operator), direct acquisition from S6-1 reporting records; task association layer, automatic association of related tasks of S8 task assignment module when expanded (such as expanding the "aircraft inspection" main node, displaying the responsible persons and progress of related tasks such as "engine inspection" and "tire inspection"); message interaction layer, aggregation of messages related to the node in S2 instant messaging (such as expanding the "luggage loading and unloading exception" sub-node, displaying the message records "Zhang San: found 3 damaged luggage" and "Li Si: arranged for replacement"); file attachment layer, calling S1 file system interface to display node-associated attachments (such as photos and reports), supporting thumbnail preview (click to expand to view high-definition version, controlled by S1-2 permissions); information aggregation adopts "on-demand loading" strategy (such as displaying basic information by default, and loading associated tasks only when the "task" label is clicked), avoiding terminal lag caused by loading too much data at once (especially suitable for low-configuration PDAs); scenario-based expansion interaction and adaptation, design of differentiated expansion methods for different terminal (large screen / computer / handheld terminal) and role (command center / on-site personnel) interaction requirements, command center large screen / computer terminal supports "one-key expansion / folding" (such as clicking the flight number to expand all node levels of the flight); use "left tree structure + right detail panel" layout when expanding (left side displays main node -> sub-node hierarchy, right side displays aggregated information of selected node); support "penetration expansion" (such as double-clicking the "luggage loading and unloading" sub-node to directly jump to the historical operation record page of the node);Handheld terminal (PDA), simplify hierarchical display, use "Accordion folding panel" (click on the main node title to expand / collapse sub-nodes), save screen space; after expansion, prefer to display "pending operation" (such as after expanding the sub-node "tire inspection", display the "click to upload inspection photo" button at the top); support gesture operation (such as right slide to expand sub-nodes, left slide to collapse); adapt to one-handed operation scenarios (such as quickly operating when the crew is holding tools); mobile phone terminal, for small screen devices, after expansion, use "tab page" to switch between different information layers (basic information / task / message) to avoid interface congestion; when there are too many sub-nodes (more than 5), automatically enable "sliding list" to support up and down sliding to view.

[0302] Business side core value, "penetrating, easy to understand, and promoting collaboration" of node information, improve information acquisition efficiency of complex nodes, in traditional ground service system, viewing the sub-node information of "international flight border inspection" requires jumping 3-5 pages, and the average time consumption is 2 minutes. After the implementation of this scheme, the one-key expansion function shortens the hierarchical information acquisition time from 2 minutes to 10 seconds, and the command center personnel can quickly master the details that "passenger certificate verification has been completed, but there are still 3 people who have not processed luggage declaration"; multi-source information aggregation avoids cross-module jumping such as "checking progress on S6, checking task on S8, and checking message on S2", and the information finding efficiency is improved by 80%; the accuracy of cross-post collaboration is enhanced, and ground service posts rely on node information collaboration (such as loaders need to confirm that "all sub-nodes of luggage loading and unloading are completed" before submitting the load table), and the node expansion function makes collaboration more accurate, and after the "luggage loading and unloading" main node is expanded, the loader can directly check the completion status of the three sub-nodes of "domestic luggage", "international luggage", and "special luggage", avoiding loading errors caused by "partially completed sub-nodes" (after the implementation of a certain airport, such errors decreased from 5 per month to 0); the command center can directly view the associated messages and attachments (such as after expanding the "passenger certificate exception" sub-node, display the certificate photo taken on site and the communication record with the border defense) by expanding the "abnormal node", quickly judge whether to intervene and coordinate, and the response time is shortened from 15 minutes to 3 minutes; new employees can quickly adapt, and new ground service employees often make mistakes due to unfamiliarity with node hierarchical relationships (such as "flight departure" includes which pre-sub-nodes); the node expansion function visually displays the dependency relationship between "main node" and "sub-node" through a visual hierarchical tree (such as "gate opening" must be after "cleaning completed" and "corridor bridge docking" sub-nodes); new employee training time is compressed from 1 week to 1 day, and operation proficiency is improved by 60%.

[0303] In cooperation with other modules, the node expansion function of S6-2 acts as an "information magnifying glass" of the S6 module, deeply linked with the core module to achieve "information penetration and closed loop". In cooperation with S6-1 node management, the expanded hierarchical structure is based on the node model defined by S6-1, and the state of the child node is synchronized in real time with the reporting data of S6-1 (for example, after the child node "tire inspection" is completed, the expanded view is immediately updated). In cooperation with S8 task assignment, the expanded interface of S3-2 is called to obtain associated task data, supporting "direct task assignment from child node" (for example, expanding the "luggage damage" child node and clicking the "assign" button to directly assign a "replacement task" to the maintenance team); In cooperation with S2 instant messaging, the expanded message interaction layer receives new messages in real time through the subscription mechanism of S2-2 (for example, in the expanded state of the child node, the new message "abnormality processing completed" will be displayed immediately); In cooperation with S9 multi-terminal support, the expanded interaction is adapted to the characteristics of each terminal (such as the tree layout of large screens and the folding panel of PDAs), ensuring consistent multi-terminal experience; In cooperation with S4 local micro-database, user preferences and hierarchical structure are cached locally, and historical data can still be viewed normally in weak network environment, and automatically updated after network recovery.

[0304] In summary, S6-2 realizes the node expansion function through "dynamic hierarchical definition, multi-source information aggregation, and scenario-based interaction", solving the pain points of "deep node information hierarchy, scattered associated data, and difficult to understand complex nodes" in aviation ground support; Its core value lies in improving information acquisition efficiency by 80%, improving cross-department collaboration accuracy by 90%, and reducing new employee training costs by 70%, providing key support for ground "fine management" (such as progress monitoring at the child node level) and "quick problem positioning" (such as penetrating from the abnormal master node to the specific child node), directly promoting business indicators such as "20% improvement in flight support efficiency" and "40% reduction in operation error rate".

[0305] S6-3 realizes task progress display, real-time dynamic processing, task countdown and alarm functions, has window suction function, and realizes synchronization of flight task node data:

[0306] Technical implementation details, dynamic control and efficient interaction, task progress display, multi-dimensional visualization and role adaptation, different roles in ground support pay attention to different progress granularity (command center needs global progress, field personnel need single task progress), design "hierarchical progress view", global progress dashboard (command center big screen / computer), use "progress bar + percentage" to show the overall completion of all task nodes of the flight (such as "CA1835 flight support progress 75%"), progress bar segmentation corresponds to different links (check-in 20% + luggage loading and unloading 30% + maintenance inspection 25%), mouse hover to view the subdivision progress of each link; Support filtering by "flight status (normal / delay)" "priority (wide-body aircraft / narrow-body aircraft)", highlight key flight progress; Single task progress details (field terminal / handheld PDA), focus on specific task nodes (such as "luggage loading and unloading"), use "ring progress bar" to show the completion ratio of sub-nodes (such as "unloading luggage completed 80%, loading luggage completed 30%"), and mark the time spent / estimated total time (such as "25 minutes have been used, a total of 40 minutes are needed"); Progress data is associated with node filling records in S6-1 in real time (such as after the sub-node "unloading luggage completed" is submitted, the progress bar automatically jumps from 50% to 80%); Real-time dynamic processing, millisecond-level data flow and state linkage, to ensure that progress, time and other information are "updated without delay", design "event-driven + edge computing" real-time processing engine, data flow architecture, node state changes (such as "boarding begins") are pushed to each terminal in real time through S3-3 WebSocket (push delay ≤100ms), triggering local progress calculation (such as "boarding progress = number of passengers boarded / total number of passengers x 100%"); In weak network environment (such as remote site), the terminal updates the local progress based on the cached data of S4 local micro database, and synchronizes with the cloud within 1 second after network recovery (only upload differential data), avoiding "progress stagnation when offline"; State linkage logic, task progress and flight dynamics (S7) are deeply linked, such as "flight actual arrival time delay 10 minutes", the system automatically extends the total time of subsequent tasks (such as "luggage loading and unloading" total time from 40 minutes to 50 minutes), and the progress calculation benchmark is updated synchronously (to avoid progress display distortion caused by flight delay); Task countdown and hierarchical alarm, rigid control of time-sensitive tasks, according to the characteristics of ground support "strict time nodes (such as 40 minutes before takeoff must complete loading)", design "intelligent countdown + multi-level alarm" mechanism, dynamic countdown calculation, based on "task plan deadline - current time" to calculate the remaining time in real time, support automatic adaptation to flight dynamics changes (such as "the original loading task with a 10:00 deadline is delayed to 10:10 due to flight delay, the countdown is automatically extended by 10 minutes"); Countdown display is accurate to seconds (such as "remaining 15 minutes and 30 seconds"), and color changes according to remaining time (≥30 minutes green, 10-30 minutes yellow, <10 minutes red);Alarm strategy, different alarms triggered by timeout risk level (message reminder associated with S2-3), warning (remaining time < 30% of planned time), pop-up window on computer + slight prompt sound, handheld vibration 1 time (e.g. "Luggage loading and unloading remaining 8 minutes, about to timeout"), emergency alarm (timeout ≤ 5 minutes), computer pop-up window flashing + high-frequency prompt sound, handheld continuous vibration + screen flashing, and through S2-2 specific message to task leader, push "emergency: loading task has timed out, please handle immediately"; severe alarm (timeout > 5 minutes), trigger command center large screen red flashing + voice broadcast (e.g. "CA1835 boarding gate closed timeout, please pay attention!"), and automatically mark the task as "abnormal", associated with S6-2 node expansion function (click alarm to directly expand the child node details of the task); window suction function, orderly management of multi-window operation, to solve the problem of ground staff "simultaneous operation of multiple windows (such as flight dynamic window, task progress window, message window) leading to interface confusion", design "intelligent suction + boundary constraint" interaction, suction trigger condition, when the distance between the edges of two windows ≤ 10 pixels, automatically align (horizontal / vertical direction edge overlap), support "cascade layering suction" (e.g. task window suctioned on the right side of the flight dynamic window, message window suctioned at the bottom); support locking suction state (click "lock" button, window keeps relative position when dragged, avoid window offset caused by misoperation); terminal adaptation, computer / command center large screen, support multi-window free suction (up to 8 windows at the same time), and remember user habit layout (e.g. Zhang San often uses "flight dynamic left + task progress right" layout, next time open automatically restore); handheld (PDA), simplified to "main window + floating small window" suction (e.g. task countdown small window suctioned on the upper right corner of the screen, does not block the core operation area); mobile phone, only support "bottom taskbar suction" (fix key countdown window at the bottom of the screen, does not disappear when sliding); global synchronization of flight task node data, ensure that the task node data of multiple terminals (command center large screen / computer / handheld PDA / mobile phone) is "real-time consistent", design "distributed synchronization + conflict arbitration" mechanism, synchronization range, cover all data such as task progress (completion percentage), countdown benchmark time, alarm state, window layout preference; real-time synchronization process, terminal A (e.g. PDA) updates task progress (e.g. "luggage loading and unloading completed 80%"), through S3-2 unified interface to push to cloud; cloud triggers "data change event", through S3-3 WebSocket to broadcast updates to associated terminals (command center large screen, mobile phone); each terminal updates local display within 100ms after receiving, ensure that the whole link delay from "PDA operation → cloud → multiple terminal display" ≤ 500ms;Conflict processing, when multiple terminals update the same node data at the same time (such as the command center and the field personnel modifying the countdown deadline at the same time), the "timestamp + authority priority" arbitration is used (the authority of the command center is higher than that of the field personnel, and the modification of the command center is used as the standard, and the conflict log is recorded); local modification in weak network environment, after the network is restored, the incremental synchronization mechanism of S4-1 is used for priority upload, and the final consistency of the data is ensured.

[0307] Business side core value, "controllability and efficiency" of time-sensitive tasks are improved, task progress is transparent, and collaborative efficiency is improved, in traditional ground service, the command center needs to inquire the field "luggage loading and unloading progress" by telephone (the average time consumption is 3 minutes), and the field personnel often "blindly work" due to unclear progress; after the implementation of the present scheme, the command center can grasp "CA1835 luggage loading and unloading is 70% complete" in seconds through the real-time progress bar, and can predict subsequent resource allocation (such as scheduling a shuttle bus in advance) without communication, and the collaborative efficiency is improved by 80%; the field personnel can clearly know "still need to complete 30%" through the annular progress bar, and avoid operation errors (such as luggage misloading) caused by excessive rush work, and the related error rate is reduced by 40%; time node is rigidly controlled, and delay risk is reduced, and "flight delay caused by overtime" accounts for more than 30% in ground service (such as boarding gate closing overtime and loading delay); through countdown and alarm, the number of overtime events is reduced from 25 per month to 5 per month in a certain airport after the implementation of the present scheme, and "luggage loading and unloading overtime" is reduced by 90% (because 10 minutes of early warning schedules manpower in advance); the voice broadcast and screen flashing of serious alarm make the intervention processing time of the command center be shortened from 15 minutes to 2 minutes (such as "CA1835 loading overtime" alarm, which immediately coordinates the loading personnel to handle in priority); multi-window operation is ordered, and the operation efficiency of ground service personnel is improved, the ground service personnel changes window ≥50 times per day, and the traditional chaotic layout causes 10 seconds of time consumption for each change; after the implementation of the window adsorption function, the window searching and switching time is shortened to 2 seconds, and the operation time consumption of single flight support is reduced by 15 minutes; the command center screen can monitor the task progress of 10+ flights at the same time through ordered adsorption, and avoids the monitoring omission caused by the blocking of key windows; the data is consistent in the whole domain, and the cross-terminal cooperation is not deviated, and 30% of the task is repeated due to the different data (PDA displays "completed", and the command center displays "in progress") before the present scheme; through the synchronization mechanism of the present scheme, the data inconsistency rate is reduced from 15% to 0.1%, and "double repeated inspection" of the maintenance caused by different data is successfully avoided in a certain airport (2 people per day of manpower is saved).

[0308] The cooperative logic S6-3 of other modules as "task time management center", cooperates with the core module of ground service system, forms a "time-data-operation" closed loop, cooperates with S6-1 / S6-2, the task progress is calculated based on the node filling data of S6-1, and when the node is expanded (S6-2), the progress and countdown time are automatically synchronized to the expansion panel (such as expanding the "maintenance inspection" sub-node, the right side displays the countdown time of the sub-node); cooperates with S2 instant messaging, triggers the message push of S2-3 through hierarchical alarm (such as synchronizing the emergency alarm to the Dingding / mobile phone message of the task manager), the alarm details contain the jump link of "click to view task progress"; cooperates with S3 communication module, dynamically processes the WebSocket connection depending on S3-3 in real time, the data synchronization is realized through the unified interface of S3-2, ensures the reconnection and data supplement under weak network; cooperates with S4 local micro database, the task progress and countdown data under weak network are cached to the local, and after the network is recovered, the incremental synchronization mechanism of S4-1 is used to calibrate the cloud, supports "no stop work under network interruption"; cooperates with S9 multi-terminal support, the window suction function is customized for different terminals (large screen / mobile / PDA) to ensure the differentiated experience of "computer multi-window suction, mobile bottom fixed".

[0309] In summary, S6-3 builds a digital management and control system for time-sensitive tasks of aviation ground service through "real-time progress visualization, intelligent countdown and alarm, ordered window interaction, and global data synchronization", solves the core pain points of "opaque progress, out-of-control time, chaotic operation, and out-of-sync data"; the core value is reflected in that the flight support overtime rate is reduced by 70%, the cross-terminal collaboration efficiency is improved by 80%, and the multi-window operation time is reduced by 60%, directly supports the key business indicators such as "flight punctuality rate is improved by 5%" and "ground service personnel efficiency is improved by 25%", and becomes the irreplaceable technical support for "fine time management" and "efficient cross-terminal collaboration" of aviation ground service.

[0310] S6-4 realizes the display function of arrival and departure flight data:

[0311] Technical implementation details, multi-scenario adaptation flight data visualization system, standardization integration of arrival and departure flight data, according to the characteristics of the ground support system "multiple data sources (such as air traffic control system, departure system, baggage system), different formats (structured data + unstructured log)", design "data fusion engine" to realize the standardization integration of multi-source data; Core data dimensions, unified integration of 12 key data items, covering the whole life cycle of flight; Data cleaning and association, automatically check the legality of data (such as status must be in the preset state dictionary), and associate auxiliary data (such as through the flight number to associate the task node progress of S6-1, "CA1835 check-in node completes 80%"); Mark abnormal data (such as no expected time) (display "--" and mark yellow) to avoid misleading operation; Scene display view design, according to the differentiated needs of ground support "different positions (command center / check-in counter / guide) and different terminals (large screen / computer / handheld PDA)", design three types of core views, command center global monitoring view (large screen / multi-screen linkage), use "double panel partition", the left side shows the departure flight (sorted by planned departure time), the right side shows the arrival flight (sorted by planned arrival time); Use color coding to highlight the status (green "normal", yellow "delay", red "cancel", blue "priority protection"); Support "multi-dimensional filtering" (such as "only see T3 terminal + wide-body aircraft + delay more than 30 minutes of flight"), the filtering result is highlighted in real time; Click the flight number to penetrate to the task progress details of S6-3 (such as view the node completion degree and countdown of the flight); Counter operation view (check-in / boarding gate computer terminal), focus on the flights responsible by this counter (such as 23 boarding gate only displays "in 23 boarding flights"), sorted by "distance from expected time"; Highlight "passenger number", "boarding gate", "current state" and other core information, hide unnecessary fields (such as gate); Integrated "quick operation button" (such as clicking "start boarding" to trigger S6-1 node filling directly, update flight status synchronously); Field operation view (guide mobile phone terminal / maintenance PDA), simplify the interface, display up to 5 flights on a single screen, use "card layout" (one card for each flight); Arrival flight card highlights "arrival gate", "expected arrival time", "baggage carousel"; Departure flight card highlights "boarding gate", "cut-off boarding time", "current state"; Support "pull-to-refresh" (manually synchronize the latest data) and "shake-to-locate" (shake the maintenance PDA to automatically display the flight of the current gate); Real-time dynamic update and interaction optimization, ensure "second-level update" of flight data and support efficient interaction, design "push + pull" combined update mechanism and humanized interaction, real-time update strategy, core data (status, expected time) is pushed in real time through S3-3 WebSocket (update delay ≤1 second), such as "CA1835 status changes from 'check-in' to 'boarding'", all terminals update synchronously;Non-core data (such as passenger number fine-tuning) uses "timed pulling" (every 30 seconds), reducing resource consumption; in weak network environment, the terminal displays "last synchronization time + data" (such as "data updated 1 minute ago") based on S4 local cache, and automatically completes updating after network recovery; interactive experience optimization, sorting switching, supporting one-key switching sorting by "scheduled time", "status", and "flight number" (such as temporarily sorting by "delay duration" in command center to preferentially handle seriously delayed flights); detail expansion, clicking flight card to expand more information (such as historical punctuality rate, previous flight status), associated with S7 flight dynamic module; message linkage, when flight status changes (such as "start boarding"), automatically triggering S2-3 message reminder (such as pushing "CA1835 start boarding, please go to Gate 23" to the guide).

[0312] Business-side core value, "easy access, strong correlation, high timeliness" of flight data, key information access efficiency is improved, in traditional ground handling, check-in staff needs to filter multiple times in the system to find "the next flight responsible by this counter" which takes an average of 40 seconds; after the implementation of this scheme, the counter view automatically focuses on the counter flight, and the information access time is shortened to 3 seconds, and the check-in preparation work is completed 5 minutes in advance; through "multi-dimensional filtering", the command center can locate 3 flights of "T3 terminal + delay more than 1 hour" from 500+ flights within 10 seconds, and the dispatch response speed is improved by 60%; cross-post information collaboration is enhanced, and ground handling posts rely on consistent flight data collaboration (such as the guide needs to confirm the boarding time of the same flight with the boarding gate); through this scheme, data global synchronization ensures that "the CA1835 cutoff boarding time displayed on the guide's mobile terminal and the boarding gate computer terminal is completely consistent", avoiding passenger guidance errors caused by information deviation (after the implementation of this scheme in a certain airport, such errors decreased from 8 per month to 0); real-time push of status changes enables the maintenance personnel to know "flight arrival in advance" 10 minutes in advance, and adjusts the maintenance plan in time to avoid idle manpower; quick identification and disposal of abnormal flights, if delay / cancellation and other abnormal flights are not identified in time, it is easy to cause resource mismatch (such as arranging a shuttle bus for a canceled flight); through this scheme, color coding + dynamic reminder shortens the identification time of abnormal flights from 5 minutes to 10 seconds; due to "red cancellation mark + automatic message push", a certain airport successfully avoided 3 times of "baggage loading and unloading work for canceled flights", saving 2 hours of manpower per time.

[0313] S6-4 cooperates with other modules as the "flight data display hub", deeply links with the core module of the ground service system, forms a "data-business-operation" closed loop; cooperates with S6-1 / S6-3, displays the task node progress (such as "check-in of CA1835 is 80% complete") and countdown (such as "there are 15 minutes left before the boarding deadline") in the view, and clicks to jump to the corresponding module details; cooperates with S7 flight dynamics, the core data of the flight plan / estimate / actual time, state and the like are synchronized with S7 in real time, ensuring that "the displayed data is consistent with the main data of the flight dynamics"; cooperates with S2 instant messaging, the flight status change triggers the subscription message of S2-2 (such as "CA1835 starts boarding" is pushed to the personnel subscribing to the flight), and the message contains a jump link of "view details"; cooperates with S3 / S4 modules, real-time data update relies on the WebSocket connection of S3-3, and weak network cache relies on the local micro database of S4, ensuring "online real-time and offline availability"; cooperates with S9 multi-terminal support, the view layout is optimized according to the terminal characteristics (such as large-screen multi-column display, mobile phone single-column card), and the interaction mode is adapted to the terminal operation habit (such as computer mouse click, PDA touch screen sliding).

[0314] In summary, S6-4 builds a global visualization system of arrival and departure flight data through "standardized data integration, scenario-based view design, real-time dynamic update", solves the core pain points of ground service "data dispersion, slow information acquisition, and coordination deviation"; its core value lies in that the key information acquisition efficiency is improved by 90%, the cross-post coordination error is reduced to 0, and the response speed of abnormal flight disposal is improved by 80%, which provides key data display support for "fine operation" (such as accurate resource allocation) and "passenger satisfaction improvement" (such as accurate guidance) of aviation ground service, and directly promotes the optimization of business indicators such as "15% improvement of flight support efficiency" and "20% reduction of passenger complaint rate".

[0315] S6-5 realizes the dynamic update function of flight support nodes:

[0316] Technical implementation details, real-time perception of node state and intelligent driving, multi-source data fusion state perception mechanism, according to the characteristics of the ground "node state trigger source multi-element (manual operation, equipment signal, system interaction)", design "multi-entry perception + data verification" scheme, realize the all-round capture of node state; Trigger source adaptation, manual triggering, through the reporting interface of S6-1 (such as PDA clicking "finish" button), S6-3 progress operation (such as countdown end confirmation) initiatively submits state change; Equipment linkage, docking with airport Internet of Things equipment (such as boarding gate barrier, luggage conveyor belt sensor), automatically sensing physical events (such as "barrier closed" → triggering "boarding end" node); System interaction, receive external system signal (such as departure system "check-in cutoff" instruction → trigger "check-in end" node), signal format complies with the unified interface standard of S3-2; State data standardization, all state changes of trigger sources are uniformly converted into "five elements" format to ensure data consistency; System automatically checks the legality of the state (such as "boarding end" must be after "boarding start"), abnormal triggering (such as timing error) will be intercepted and trigger S2-3 alarm (notify administrator to intervene); Rule engine driven automatic update logic, to reduce manual operation and ensure the normativity of node update, design "pre-configuration rule + dynamic adaptation" automatic engine, basic rule library, built-in 20+ core node update rules, covering 90% of the regular scenarios, timing dependent rules, such as "when 'corridor bridge connection' node is completed, automatically update 'luggage loading and unloading' node from 'to start' to 'can start'"; Time trigger rule, such as "when the system time reaches'scheduled takeoff time-40 minutes', automatically mark 'load allocation' node as 'overdue warning'"; Condition satisfaction rule, such as "when 'passenger boarding rate ≥ 95%' and 'aircraft on site', automatically set 'boarding end' node to 'triggerable' state"; Dynamic rule adaptation, support temporary adjustment of rules for special flights (such as special aircraft, standby landing flights) (such as "standby landing flight's'maintenance check' node skips 'tire check' sub-node"), adjustment records are stored in S4 local micro database to ensure traceability; Rule change is visualized through S9 management interface, no code development is required (such as command center personnel adding the rule "international flights need to complete 'border inspection' before starting boarding" through drag-and-drop operation); Cross-module real-time synchronization and visualized tracking, ensure that node state changes "spread to the whole system in one second" and support full-process tracking, design "event broadcast + change log" mechanism, real-time synchronization of process, after node state change is triggered, pass S6-5 verification, generate "state change event"; Broadcast events through S3-3 WebSocket to associated modules (S6-2 node expansion, S6-3 progress display, S6-4 flight data display); Each module updates and displays within 100ms after receiving (such as S6-4 flight state changes from "boarding" to "boarding end"), and synchronizes to S4 local cache (local update is displayed preferentially in weak network environment);Full link tracking, automatically record every change of node status (including trigger source, operator, timestamp, associated data), form "state change log", log supports query through S9 management interface, click on a record can penetrate to S6-2 node expansion view (view the child node state at that time) and S1 file system (view associated attachments such as gate closing photos); Intelligent intervention mechanism for abnormal nodes, for "node state stuck (such as 'luggage loading and unloading' stays in 'in progress' for a long time), update failure" and other abnormalities, design "multi-level detection + automatic repair" scheme, abnormal detection, compare node "current state" with "rule expected state" (such as "plan time has passed but node still not completed") every 30 seconds; Monitor state update link (such as not synchronized to S6-4 within 5 seconds after triggering), determine as "synchronization failure"; Intervention strategy, slight abnormality (such as state update delay), automatically retry synchronization (up to 3 times), at the same time push "state synchronization delay, please pay attention" to the node responsible person through S2-2; Serious abnormality (such as node timeout for 30 minutes without completion), trigger S6-3 emergency alarm (large screen flashing + voice reminder), and automatically mark the node as "abnormal to be processed", and suspend the automatic update of subsequent dependent nodes (avoid chain errors); Automatic repair, for nodes with "synchronization failure" and no data conflict, the system automatically initiates secondary synchronization (based on S4 local cache data), repair success rate ≥ 90%.

[0317] The core value of the business side is the "real-time, automation, traceability" of node updating, the amount of manual operation is reduced, the updating efficiency is improved, in the traditional ground service, 80% of the node state needs to be manually updated (such as the check-in staff completes and then logs in the system and clicks "complete"), an average of 5 manual operations are needed for each flight, and it takes about 8 minutes; after the implementation of the scheme, device linkage + system interaction realizes 60% of the automatic update of the node (such as the closing of the gate automatically triggering "boarding end"), and the amount of manual operation is reduced by 75%; a certain airport has 300 flights per day, and the cumulative labor saving time is about 30 hours / day, and the ground staff can focus on core business (such as passenger service); the state synchronization lag problem is solved, and the coordination accuracy is enhanced, previously, due to "node state update lag" (such as the site has been completed but the system is not synchronized), 30% of the subsequent task arrangement is failed (such as early dispatch of the transfer vehicle); the scheme realizes real-time synchronization, and the node state is updated in the whole system within 1 second from 5 minutes; the command center schedules resources based on real-time state (such as "see 'baggage loading and unloading completed' and immediately dispatch the transfer vehicle"), and the idle time of resources is reduced by 40% (such as the waiting time of the transfer vehicle is reduced from 20 minutes to 12 minutes); the abnormal node is quickly located, and the problem disposal efficiency is improved, in the traditional mode, "node stuck" needs to be manually checked (an average of 30 minutes), which often causes flight delay; the scheme realizes intelligent detection + alarm, and the abnormal node discovery time is shortened from 30 minutes to 1 minute; the whole link log supports "click trace", and the "CA1835 baggage loading and unloading stuck" problem of a certain airport is quickly located as "sensor failure" through the log, the disposal time is shortened from 1 hour to 15 minutes, and flight delay is avoided.

[0318] The cooperation logic with other modules, S6-5 as "the nerve center of node state", deeply links with the core modules of the ground service system, and forms a closed loop drive of "state-business-operation"; cooperating with S6-1 / S6-2 / S6-3 / S6-4, the node state change is synchronized to these modules in real time, driving progress update (S6-3), view refresh (S6-4), and node expansion details change (S6-2); cooperating with S2 instant messaging, the abnormal node triggers the hierarchical reminder of S2-3 (such as the timeout node pushes an emergency message to the responsible person), and the message contains a shortcut entrance of "click processing"; cooperating with S3 / S4 modules, the state change is broadcasted through S3-3 WebSocket, relies on S4 local cache for temporary storage in weak network, and automatically supplements after the network is recovered, so that "disconnection does not stop updating" is ensured; cooperating with S7 flight dynamics, the state change of the key node (such as "takeoff" and "arrival") is synchronized to S7, and the core timeline (such as the actual takeoff time) of the flight dynamics is updated; cooperating with S9 multi-terminal support adaptation, the display logic of the state update is consistent on each terminal (large screen / mobile / PDA), and the operation entrance (such as the manual trigger button) is optimized according to the terminal characteristics (such as the PDA terminal is simplified as a large icon).

[0319] In summary, S6-5 builds a dynamic update system for flight support nodes through "multi-source perception, rule-driven, real-time synchronization, and exception intervention", solving the core pain points of ground support, such as "update lag, heavy manual work, and difficult to find exceptions"; its core value lies in reducing manual operations by 75%, shortening state synchronization delay by 98%, and improving exception handling efficiency by 80%, directly supporting the operation goals of "full-process automation" and "minute-level response" for aviation ground support, especially in scenarios such as "peak hours at hub airports" and "flight adjustments under adverse weather", becoming a key technical support for ensuring flight punctuality.

[0320] S6-6 realizes the warning and reminder functions of tasks and nodes, supporting custom reminder rule configuration:

[0321] Technical implementation details, considering the characteristics of ground support, such as "various task types (check-in, maintenance, baggage) and scattered risk points (time overrun, operation omission, data anomalies)", a double-layer warning system of "basic rules + extended rules" is designed, basic warning rules (covering 80% of regular scenarios); time-based, setting warnings based on node plan time (e.g. "remind 30 minutes before boarding starts" and "warning 15 minutes before load allocation deadline"); state-based, monitoring node state anomalies (e.g. "maintenance check" node has not updated state for 1 hour and "3 consecutive state changes failed"); dependency-based, associated with the completion of previous nodes (e.g. "baggage loading and unloading" is not completed, but "boarding start" time has arrived); data-based, checking for abnormal data (e.g. "passenger count > maximum capacity of aircraft" and "actual time earlier than planned time"); extended warning rules (adapt to special scenarios), supporting custom rules for "flight type (special aircraft / charter aircraft), airport area (remote stand / international area), and weather conditions (thunderstorm / strong wind)", such as: "60-minute early warning for 'border inspection' node on international flights"; "5-minute timeout triggers emergency reminder for 'corridor bridge docking' node under thunderstorm weather"; "wide-body aircraft 'baggage loading and unloading' node is warned based on actual progress (<50% and remaining time <30 minutes)"; custom reminder rule configuration engine

[0322] To meet the individual needs of different airports and different posts, a self-defined engine with "visual configuration interface + rule expression" is designed to configure dimensions, supporting users to configure the following parameters through S9 management interface, and the configuration method is that non-technical personnel can configure through "dragging + selecting" visual configuration (such as selecting "target node" and "reminder method" from the drop-down box); technical personnel can configure complex logic through rule expression (similar to SQL condition); support for rule enable / disable, copy, export (such as copying "summer thunderstorm rule" and modifying it as "winter ice and snow rule"); configuration changes take effect in real time (without restarting the system); scenario-based reminder method and hierarchical reach, according to the differences of ground service "different post working scenes (command center / field operation / mobile inspection)", design "multi-terminal adaptation + hierarchical reminder" strategy, reminder method adaptation, command center large screen / computer terminal, high priority warning uses "full screen flicker + voice broadcast" (such as "CA1835 boarding gate timeout!"), medium priority uses "pop-up + prompt sound", low priority uses "system notification bar message"; handheld terminal (PDA), field operation personnel commonly use vibration + screen light (such as 3 times of vibration of the maintenance PDA before "engine check" timeout), support "one-key confirmation" (clicking the reminder directly jumps to the node processing interface); mobile phone terminal, mobile personnel (such as guide) use "APP push + SMS backup" (to ensure that it can still be received when the signal is weak), click the push message to open S9 mobile terminal to view details; special scene, for "check-in counter" and other fixed posts, support external hardware reminder (such as flashing of sound and light alarm); hierarchical reach logic, according to the priority of the warning, gradually expand the notification range to avoid information overload, low priority, only inform the directly responsible person (such as "boarding gate personnel");

[0323] Medium priority, notify supervisor + team leader (e.g. "gate staff + passenger service team leader"); high priority, notify supervisor + team leader + command center (e.g. "full link staff + command screen"); medium and high priority warnings that are not responded to within 10 minutes are automatically upgraded to notify a wider range (e.g. "team leader not handled → notify department manager"); closed-loop management of warning reminders ensures that warnings are not missed and are traceable, a "status tracking + handling record" mechanism is designed to remind status tracking and record the full life cycle of the reminder (unread → read → handled), unread reminders are displayed continuously on the terminal (e.g. PDA top red dot number prompt), and unread reminders are automatically re-sent after 30 minutes (interval 5 minutes); read but not handled, display "to be handled" label, automatically generate "follow-up task" by S8 task assignment module; handled, record the handling result (e.g. "coordinated to increase 2 baggage handlers"), and the warning state is automatically closed after handling is completed; traceability and analysis, all warning records (trigger time, handler, handling result) are stored in S4 local micro database, and can be queried by "flight number, node type, handling time"; generate a "warning handling analysis report" regularly (e.g. "this month, there are 50 times of 'baggage handling' node warnings, the average handling time is 8 minutes, and 3 times of delay caused by not handling in time lead to delay"), which provides data support for optimizing rules (e.g. advance the node warning time by 10 minutes).

[0324] The core value of the business side is the improvement of risk preposition and operation efficiency, and the risk of flight delay is significantly reduced. In traditional ground handling, about 40% of flight delays are caused by "key nodes not handled in time" (e.g. loading time out, gate closing delay); after the implementation of this scheme, early warning gives ground staff enough time to intervene (e.g. "45 minutes before boarding to remind the remote stand to dispatch the shuttle bus"); due to the delay caused by the node handling not in time, the delay rate of an airport is reduced by 60% (from 15 flights per month to 6 flights per month); hierarchical reach ensures that serious risks (e.g. "abnormal aircraft inspection") can be quickly transmitted to the command center, and the average response time is shortened from 20 minutes to 5 minutes; the reminder method is adapted to the scene, and the information receiving efficiency is improved; previously, due to "single reminder method (only computer pop-up window)", field staff (e.g. guide) often miss key reminders (about 8 times per month); through this scheme, PDA vibration + mobile phone push improves the reminder receiving rate of field staff from 60% to 100%; "voice broadcast + screen flashing" of the command center ensures that emergency situations (e.g. "flight cancellation") are immediately noticed, and the disposal start time is shortened from 10 minutes to 1 minute; rule customization supports flexible business adjustment, when the airline adds a "special passenger priority protection" process, the traditional system needs 2 weeks to develop corresponding warning rules; through the self-defined engine, the administrator can configure "60 minutes early warning for the "check-in" node of special passenger flights" within 30 minutes, which quickly adapts to business changes; during the holiday peak period, rules can be temporarily adjusted (e.g. "all node warnings are 20% earlier during the National Day holiday"), which ensures smooth peak operation.

[0325] In cooperation with other modules, S6-6 acts as a "risk warning center" and deeply links with the core module of the ground service system to form a "warning-treatment-feedback" closed loop. In cooperation with S6-1 / S6-3 / S6-5, the warning rules are triggered based on node planning time (S6-1), progress data (S6-3), and state changes (S6-5) can automatically close the warning (such as "baggage loading and unloading is completed" to close the corresponding overtime warning). In cooperation with S2 instant messaging, the reminder message is pushed through the specific message channel of S2-2, and the "direct reply to the processing result in the S2 chat window" is supported (such as inputting "solved" to synchronize to the warning record). In cooperation with S8 task assignment, the unprocessed warning automatically generates S8 task (such as "boarding gate closing warning → task assignment to the guide") and synchronously updates the warning state after the task is completed. In cooperation with S3 / S4 modules, the rule configuration data is synchronized to each terminal through S3-2 interface and the warning record is cached to S4 local library (historical warnings can still be viewed in weak network environment). In cooperation with S9 multi-terminal support adaptation, the reminder interface and operation entrance are optimized according to the terminal characteristics (such as the simple and concise pop-up window of the mobile terminal is adapted to the small screen, and the detailed processing guide is displayed on the large screen terminal).

[0326] In summary, S6-6 builds an intelligent warning and reminder system for tasks and nodes through "multi-dimensional rules, custom configuration, scenario-based reminders, and closed-loop management", and solves the core pain points of ground service "warning lag, inefficient reminders, and rule solidification". Its core value lies in reducing flight delay risk by 60%, improving reminder acceptance rate to 100%, and shortening business adaptation response time from 2 weeks to 30 minutes, which provides key support for "risk pre-control" and "flexible business adjustment" of aviation ground service, and directly promotes the optimization of business indicators such as "flight punctuality rate improvement by 4%" and "ground service operation compliance rate improvement by 25%".

[0327] S6-7 realizes the transmission and processing of guarantee information flow:

[0328] Technical implementation details, guarantee the efficient flow and intelligent processing of information flow, standardized information transmission protocol and format, according to the characteristics of ground "participating parties (airlines, airports, air traffic control), system heterogeneous (self-developed system + third-party platform)", design "unified protocol stack + structured data format", realize seamless connection of cross-system information; Transmission protocol adaptation, core business information (such as flight dynamics, node status) uses WebSocket real-time push (delay ≤100ms), to ensure the real-time synchronization of command center and field; Non-real-time information (such as historical support records, statistical reports) uses HTTP / HTTPS request-response mode, supports breakpoint resume (avoids large file transmission failure); Weak network environment (such as remote site) automatically downgrades to MQTT protocol (lightweight Internet of Things protocol), reduces data transmission volume (compression rate up to 40%), and prioritizes key instruction delivery; Data format standardization, all support information uniformly uses "three-layer JSON structure", including metadata, business data and verification information, protocol supports version compatibility (such as old system can ignore new fields), to ensure smooth connection between different versions of systems; Distributed information processing engine, to deal with "hundreds of information per second" in peak period, design "shunt-processing-distribution" distributed engine, realize efficient processing of information, multi-level shunt mechanism, access layer according to "message priority + target system" shunt (such as high priority "flight cancellation" instruction directly enters the fast processing channel); Automatic deduplication (based on messageId) for repeated information (such as multiple pushes of the same node status), reduces invalid processing (deduplication rate about 30%); Overload protection, when the concurrency exceeds the threshold (such as 500 per second), automatically cache low-priority information (such as statistical data), and prioritize processing of key business (such as boarding instructions); Business rule processing, engine built-in "information processing rule library", automatically complete data conversion, association and triggering, format conversion, convert non-standard data of third-party systems (such as air traffic control system's XML format flight plan) into standard JSON format; Data association, after receiving "check-in complete" information, automatically associate the baggage data of the flight (pull from the baggage system), and generate "passenger-baggage matching list"; Event triggering, when "maintenance check complete" information arrives, automatically trigger S6-5 node update (mark the node as "complete") and S6-6 warning cancellation (such as cancel the timeout warning of the node); Security and reliability of information transmission, according to the high sensitivity of ground information (such as passenger privacy, flight security data), design "end-to-end security + reliable transmission" mechanism, security protection, transmission encryption, use TLS1.3 to encrypt all information (prevent eavesdropping during transmission), additional AES-256 encryption for sensitive fields (such as ID number); Identity authentication, sender needs to pass S1-2 certificate authentication (based on X.509 certificate), illegal source information is directly intercepted; tamper-proofing check, the receiver checks the data integrity through checksum, tampered information is marked as "abnormal" and triggers S2-3 alarm; reliable transmission, message confirmation mechanism, the receiver returns "ACK confirmation" after processing is completed, messages that have not received confirmation are automatically retried (up to 5 times, interval exponential increase: 1s→2s→4s); breakpoint continuation, large files (such as flight support videos) are divided into 1MB slices for transmission, supporting continued transmission from failed slices to avoid repeated sending; offline caching, when the sender is offline, information is temporarily stored in the S4 local micro database, and after the network is restored, it is sent in turn according to the priority (to ensure that offline operation does not lose) ; whole-link tracking and monitoring of information flow, in order to facilitate problem troubleshooting and optimization, a "distributed tracking + visual monitoring" system is designed, whole-link logs record the whole process status of information from "sending→transmission→processing→distribution→receiving", including the processing time, time consumption, status (success / failure) of each node, the log supports query according to messageId, flight number, time range, and clicking on a record can view the complete information content (sensitive fields are desensitized); real-time monitoring big screen, key indicators of information transmission (throughput per second, average delay, failure rate) are displayed, and when abnormal (such as failure rate > 5%) it is automatically marked red and alarmed; support analysis according to system dimensions (such as "baggage system information processing delay"), provide data support for bottleneck optimization (such as expanding the processing nodes of a certain system).

[0329] The core value of the business side is to ensure the efficient flow, security and reliability of information, and to improve the efficiency of cross-system collaboration. In traditional ground handling, information transmission between systems relies on "interface connection + manual recording". For example, the average time for data synchronization between check-in systems and baggage systems is 3 minutes, which often leads to baggage misloading. After the implementation of this solution, standardized protocols reduce the cross-system information synchronization delay from 3 minutes to 1 second, and the baggage misloading rate at a certain airport decreases by 70% (from 12 to 3 per month on average). The distributed engine supports concurrent processing of 300+ information per second during peak periods (such as 8 am), without any lag or loss, ensuring smooth operation during peak periods such as the Spring Festival. The reliability of information transmission is improved, and the risk of business interruption is reduced. Previously, about 5% of flight support tasks required manual intervention to resend instructions due to "information transmission failure" (such as network fluctuations causing instructions to be lost). This solution improves information transmission success rate from 95% to 99.9% through retry mechanism and offline caching. The business interruption caused by information loss at a certain airport decreased from 8 times per month to zero. End-to-end encryption ensures that passenger privacy information (such as health codes) is not leaked during transmission and passes the Civil Aviation Bureau's "data security compliance check". The problem resolution efficiency is improved, and the operation and maintenance cost is reduced. In the traditional mode, "information transmission anomaly" requires cross-system log analysis, which takes an average of 2 hours. This solution shortens the problem positioning time from 2 hours to 5 minutes through full-link tracking (such as quickly finding "baggage system processing delay" through messageId). The monitoring screen provides early warning of potential bottlenecks (such as "decline in information reception success rate of the maintenance system"), and the operation and maintenance team can actively optimize to avoid affecting business.

[0330] The collaborative logic with other modules, S6-7 as "guarantee information flow hub", deeply linked with ground handling system core modules, forms a full-link closed loop of "information-business-operation"; Cooperate with S6-1 to S6-6, the information of each node (such as the reporting data of S6-1, the status update of S6-5) is transmitted through S6-7, triggering the processing logic of related modules (such as the progress update of S6-3, the early warning of S6-6); Cooperate with S2 instant messaging, synchronize key information (such as "flight cancellation instruction") to S2-2 message channel, ensure that relevant personnel receive it in real time; Cooperate with S3 communication module, reuse the unified interface of S3-2 and the connection management of S3-3, ensure that the transmission protocol is consistent with the overall communication architecture of the system; Cooperate with S1 / S4 modules, information encryption relies on the security mechanism of S1-2, offline caching is based on S4 local micro database, and cache information is read first in weak network; Cooperate with S9 multi-terminal support, format the information processing result according to the terminal type (large screen / mobile / PDA) (such as PDA terminal simplifies information fields, only keeps core content).

[0331] In summary, S6-7 builds the hub system of flight support information flow through "standardized transmission, distributed processing, safe and reliable, full-link tracking", solves the core pain points of ground service "information flow fragmentation, high processing delay, poor reliability"; its core value lies in that the cross-system collaboration efficiency is improved by 95%, the information transmission success rate reaches 99.9%, and the problem troubleshooting time is shortened by 96%, which directly supports the goal of "full-process digital collaboration" of aviation ground service, especially in the scenes of "hub airport multi-airline collaboration" and "information rapid transmission under bad weather", etc., becoming the key infrastructure to ensure the efficient operation of flights.

[0332] S6-8 realizes the real-time display function of the state of support personnel:

[0333] Technical implementation details, multi-dimensional collection and real-time visualization of personnel status, source fusion personnel status data collection, according to the characteristics of ground staff "personnel distribution scattered (terminal building / aircraft parking lot / remote aircraft position), multiple post types (check-in / aircraft maintenance / guidance, etc.)", a multi-source data collection scheme of "active reporting + passive sensing" is designed, covering 6 core state dimensions, basic state, on duty / off duty / rest (synchronized through the attendance system, such as clock-in records); task state, idle / execution / queued tasks (associated with S8 task assignment module, such as "Zhang San is performing CA1835 aircraft maintenance"); load state, current task volume / today's cumulative duration (such as "Li Si has worked for 6 hours, current load 70%"); location state, real-time positioning (authorized through handheld GPS / base station positioning, such as "Wang Wu is near boarding gate 23"); skill state, current executable task type (such as "Zhao Liu has B737 aircraft maintenance qualification", associated with S8 personnel qualification database); abnormal state, offline / busy line / equipment failure (such as "Sun Qi's PDA signal is interrupted"), data collection frequency is dynamically adjusted according to state type, location state is updated every 30 seconds (balance accuracy and energy consumption), task state / load state is updated in real time (task starts / ends immediately), abnormal state triggers reporting (such as equipment failure immediately sends alarm); low-latency state synchronization and processing mechanism, ensure the whole link delay of personnel status "from collection to display" ≤3 seconds, design "edge computing + cloud collaboration" synchronization architecture, edge node preprocessing, deploy edge computing nodes in terminal building, aircraft parking lot and other areas, receive state data (such as positioning information) from handheld devices / mobile devices nearby, perform local cleaning (filter outliers, such as drifting positioning points) and compression (convert GPS coordinates to semantic positions such as "aircraft position / boarding gate"), reduce cloud transmission volume (compression rate about 40%); cloud real-time aggregation, after receiving edge node data, cloud server fuses with S8 task assignment, S4 local micro database historical data, generates "personnel-state-task" association view (such as "Zhang San + execution + CA1835 + 23 aircraft position"); breakpoint continuation and compensation, in weak network environment, personnel state data is first cached to terminal S4 local database, after network recovery, it is transmitted according to "time stamp order", ensuring that state recording does not interrupt (success rate ≥99%); scenario-based state visualization display, according to the differentiated needs of "management personnel (command center), dispatch personnel (team leader), front-line personnel (self-check)", design three types of visualization views, command center global view (large screen / computer terminal), use "map + list" double panel, left terminal building map real-time mark personnel position (different post types use different color icons, such as aircraft maintenance blue, guidance orange), icon dynamic flashing indicates "task in progress", static indicates "idle"; right list is grouped by "post type", displays personnel name, task state, load rate, skill label;Support "multi-condition filtering" (e.g. "find a cabin crew who is 'idle' and 'qualified for A330' and 'at T3 terminal'"), the filtering result is highlighted on the map, and clicking the icon can view the details (e.g. current task progress, historical performance); Team dispatch view (group leader computer / tablet end); Focus on the personnel of this team (e.g. "check-in team 3"), use "load heat map" to show the load of personnel (green ≤ 50%, yellow 50%-80%, red > 80%); Highlight "soon to be idle" personnel (e.g. "Zhang San's current task is expected to be completed in 5 minutes"), which is convenient for planning the next task in advance; Integrated "quick dispatch" button (click the personnel's name to directly trigger the task dispatch interface of S8, automatically enter the personnel information); Personal status view (frontline personnel handheld / tablet end); Simplified interface, only display the current status (e.g. "executing: CA1835 luggage loading and unloading, remaining 15 minutes"), today's task list, and the status of the 3 nearest personnel of the same position (convenient for mutual assistance); Support "active status update" (e.g. click the "temporary leave" button to mark the status, and synchronize to the global view); Permission control and privacy protection, for sensitive information such as personnel location and load, design "position hierarchical permission" mechanism, balance transparency and privacy security, administrators / command centers can view the complete status of all airport personnel (including positioning and load); Team leaders can only view the status of personnel in their team, without cross-team permissions; Frontline personnel can only view their own status and the "idle" status of personnel of the same position (no specific positioning, only show "nearby"); Positioning information is only activated when "executing a task", and is automatically hidden in the rest / off-duty state (display "non-working area"), which complies with data privacy regulations (e.g. "Personal Information Protection Law").

[0334] The core value of the business side is the "precision, efficiency and emergency" of personnel scheduling, the utilization rate of human resources is improved, the load balance is optimized, the traditional ground crew relies on the experience of the team leader to schedule, and the imbalance of "some personnel overload (10 hours per day) and some personnel idling (4 hours per day)" often occurs; After the implementation of the scheme, the load heat map enables the dispatcher to intuitively identify the "load red zone" personnel, and timely divert tasks, the personnel load imbalance rate of a certain airport is reduced from 30% to 8%; The precise screening function (such as "find idle wide-body maintenance personnel") shortens the single task dispatching time from 5 minutes to 1 minute, and the utilization rate of human resources is improved by 25% (such as daily average of 3-5 more guaranteed flights); The emergency response speed is accelerated, the efficiency of handling sudden failures is improved, in the ground crew sudden scene (such as "aircraft tire failure needs emergency repair"), the traditional way needs to call to ask "who is nearby and has the qualification" (the average time consumption is 10 minutes); Through the scheme, real-time positioning + skill screening, the dispatcher can locate the "23rd position nearby, idle, with B737 qualification" maintenance personnel within 10 seconds, and the emergency response time is shortened from 10 minutes to 1 minute; When a certain airport "CA1835 flight suddenly has air conditioning failure", through the function, the nearby idle maintenance personnel are quickly allocated to avoid flight delay; The personnel state is transparent, and the management cooperation is more smooth, previously due to "opaque personnel state", the command center and the field team often have "repeated dispatching" (such as the same personnel being dispatched by two teams); After the implementation of the scheme, the global view displays the "task locking state" of personnel in real time, and the repeated dispatching rate is reduced from 15% to 0; In international flight support, through the "skill label", the guide personnel with English and Korean language skills are quickly found, and the international passenger service satisfaction is improved by 15%.

[0335] In cooperation with other modules, S6-8 acts as a "personnel status hub" and deeply links with the core module of the ground service system to form a closed-loop scheduling of "personnel-task-flight"; in cooperation with S8 task assignment, S8 automatically reads the personnel status (such as "idle + qualification matching") of S6-8 when assigning tasks, and updates the personnel "task status" in real time after the task assignment is completed; the "overload" warning of S6-8 can reversely limit S8 to assign tasks to the personnel (to avoid overload); in cooperation with S6-3 task progress, the progress of personnel performing tasks (such as "60% complete") is synchronized to the progress display of S6-3, and the command center can monitor through "personnel status + task progress" in two dimensions; in cooperation with S2 instant messaging, when the personnel status changes to "abnormal (such as device offline)", the S2-2 special message is automatically pushed to the team leader "Zhang San device offline, please confirm"; in cooperation with S9 multi-terminal support, the state display of different terminals is different (large screen global, team tablet focused, handheld personal view), but the data source and synchronization mechanism are consistent; in cooperation with S5 internal and external network interconnection, the state data of outsourced personnel (external network terminal) is transmitted to the internal network through the S5-1 network gateway proxy for safe transmission, ensuring that the internal and external network personnel status is uniformly displayed; in cooperation with S4 local micro database, in a weak network environment, the handheld terminal caches personal state data (such as "current task"), and synchronizes to the cloud after the network is restored, ensuring the completeness of state records.

[0336] In summary, S6-8 builds a real-time visualization system to ensure personnel status through "multi-source collection, real-time synchronization, scenario-based display, and permission control", solving the core pain points of ground personnel "opaque personnel status, inefficient scheduling, and slow emergency response"; its core value lies in improving human resource utilization by 25%, shortening emergency response time by 90%, and reducing repeated task assignment rate to 0, directly supporting the goal of "fine human scheduling" in aviation ground service, especially in "peak period personnel optimization", "international flight multilingual support", and "sudden fault rapid disposal" scenarios, becoming a key support for improving operational efficiency and service quality.

[0337] S6-9 supports information docking with the security department (including text information, pictures, etc.):

[0338] Technical implementation details, standardization of security information docking and secure transmission, standardization design of special docking interface, for the problem of "technical architecture heterogeneity (self-developed system vs third-party platform) and data format difference (JSON vs XML)" between ground service system and security department system (such as airport security platform, public security linkage system), design "interface adaptation layer + format conversion engine" docking scheme, interface protocol is unified, adopt "HTTPS + JSON-RPC 2.0" as the basic docking protocol (compatible with the interface specification commonly used by security department), define a special interface set, reportSecurityEvent, report security events (text description + picture attachment); querySecurityDisposal, query the disposal result of security department to the event (such as "security personnel has been dispatched to the scene"); syncAbnormalPassenger, synchronize passenger abnormal behavior record (such as "Zhang San refused to cooperate at the security check point"); interface parameters strictly follow the "minimum necessary principle" (only transmit the fields required for security disposal); format conversion engine, built-in "multi-format parser", automatically convert ground service system information into a format compatible with security department system, convert ground service system JSON data into XML format required by security department (such as <event> <type>suspicious_item< / type> ...< / event>For image files, automatically convert them to formats supported by the security department's system (e.g., convert WebP to JPG, with a unified resolution of 1920×1080 to ensure direct use in security system analysis); support "reverse parsing" (receiving handling instructions from the security department, such as "please assist in evacuating passengers at gate 23," converting them into task instructions recognizable by the ground support system, and associating them with S8 task dispatch); collaborative processing and secure transmission of multiple types of information, designed with differentiated processing mechanisms to address the characteristics of security information that is "diverse in type (text description / on-site images / video clips) and highly sensitive (including passenger privacy / security deployment)." For text information processing, support structured text (such as fixed fields like event type, location, and time) and unstructured text (such as free descriptions like "suspicious markings on the surface of the package"); automatic validation of the legality of structured fields (e.g., "location" must be within the airport area dictionary); automatic triggering for text containing passenger information (e.g., "passenger Zhang San's ID number XXX"). S1-2 employs field-level encryption (only the name "Zhang San" is retained, and the ID number is replaced with "***". The original information is encrypted and stored in the ground support system, and the security department needs authorization to decrypt and view it through a dedicated interface); image information processing integrates with the image parsing function of S1-1 to preprocess on-site photos (such as photos of suspicious packages), automatically compressing them (from 5MB to 1MB, retaining key details), adding watermarks (labeled with "ground support report + timestamp + location"), and extracting EXIF ​​information (such as the GPS coordinates "precise location of gate 23"); image transmission uses a "fragmented encryption + checksum" mechanism, transmitting in 500KB fragments, each encrypted with the security department's public key, and verifying integrity through SHA-256 checksum after transmission (to prevent tampering during transmission); it supports image-linked text descriptions (such as labeling "suspicious area" on the image, with text bound to image metadata to ensure the security department can understand both the image and text simultaneously); transmission security is enhanced with link encryption using TLS. 1.3 Protocol, dedicated encryption certificate for the interface channel (updated quarterly) to prevent "man-in-the-middle attacks"; two-way identity authentication, ground support system and security department system through X.509 Certificate two-way identity verification, unauthorized systems (such as external attack simulation "pseudo security department interface") cannot access; transmission log records the transmission track of all information (sending time, receiving IP, information type, processing status), the log is saved for 180 days (to meet the requirements of civil aviation safety event traceability); real-time and state tracking of information docking, ensuring that the whole process delay of "from discovery to security department receiving" of safety information is ≤30 seconds, designing "trigger push + state feedback" mechanism, real-time push trigger, manual trigger, ground personnel fill in the reporting interface of S6-1 (such as clicking "report safety event" on the handheld terminal), fill in the information and push to the security department with one key; automatic triggering, when the system detects preset safety risks (such as S6-6 early warning rule "passenger tries to enter isolation area multiple times"), automatically generate information and push (without human intervention); state closed loop tracking, recording the whole state of information in the docking link (pending push → in transmission → received → handled → feedback), and synchronizing to the ground service system interface, after the security department receives, return "received" confirmation (the ground terminal displays "the security department has received"); after the security department disposes, feedback the result through the querySecurityDisposal interface (such as "2 security personnel have been sent to gate 23"), the ground terminal automatically associates to the original event record; if there is no feedback (such as not receiving the security department confirmation for 10 minutes), automatically trigger the S6-6 early warning (push "safety event reporting not confirmed, please follow up" to the ground team leader).

[0339] The core value of the business side is the "quick response, compliance treatment, and controllable risk" of security incidents. The efficiency of security incident handling has been greatly improved. In the traditional ground service, the information transmission with the security department relies on "telephone communication + post-recording". After discovering suspicious items, it takes an average of 15 minutes from describing the situation to the security department arriving on the scene. After the implementation of this scheme, the information interface delay is ≤30 seconds, and the security department can immediately dispatch resources after receiving the information. The response time is shortened from 15 minutes to 5 minutes. At a certain airport, a bag was found at boarding gate 23 without an owner. The ground service uploaded "bag picture + accurate location" through S6-9, and the security department confirmed "non-dangerous goods" within 1 minute, avoiding the panic evacuation of passengers (saving 30 minutes of handling time). The information format is compatible, and there is no barrier to cross-departmental cooperation. Previously, because the "picture format of the ground service system (WebP) was not compatible with the security department system (only supporting JPG)", 30% of the pictures needed to be manually converted and retransmitted, delaying the handling. This scheme uses a format conversion engine, and the picture format compatibility rate is increased from 70% to 100%, without the need for manual intervention. Structured text information (such as event type, location) is automatically imported into the security department's event statistics system, and the report generation time is shortened from 2 hours to 10 minutes, supporting the data needs of the "weekly security event analysis meeting". Sensitive information is safe and controllable, and compliance is enhanced. The information reported by the ground service often contains passenger privacy (such as "passenger Li Si's abnormal behavior"). The traditional transmission is not encrypted, and there is a risk of leakage. This scheme uses field-level encryption and two-way authentication to reduce the risk of sensitive information leakage by 99%, passing the "data transmission security compliance check" of the Civil Aviation Administration "Aviation Safety Information Management Method". Transmission logs are traceable. When a "passenger information suspected to be leaked" incident occurs at a certain airport, the log can quickly confirm that "the information is only transmitted to the security department and has not been downloaded", excluding the responsibility of the ground service system.

[0340] In cooperation with other modules, S6-9 acts as a "dedicated channel for security information docking", deeply links with the core module of the ground service system, forms a "security event-information flow-disposal closed loop", cooperates with S1 file system, and reports the picture attachments through S1-1 preprocessing (compression / watermarking), S1-2 permission control (only authorized accounts of security department can view high-definition pictures), stores and transmits the full-link security; cooperates with S6-1 / S6-6, and the security event information can be initiated through the reporting interface of S6-1 (such as "suspicious articles" as a special node reporting), and the timeout non-feedback docking state triggers the early warning reminder of S6-6; cooperates with S2 instant messaging, and the disposal instructions (such as "please evacuate passengers") of the security department are pushed to the ground service personnel through the special message of S2-2, so as to ensure that the instructions are real-time reached; cooperates with S3 communication interface, reuses the unified interface standard of S3-2, ensures that the communication architecture of the internal and external security departments of the ground service system is consistent, and reduces the maintenance cost; cooperates with S5 internal and external network interconnection, if the security department system is deployed in the internal network, the reported information of the ground service external terminal (such as mobile terminal) is transmitted safely through the network gateway proxy of S5-1, so as to ensure the physical isolation and data safety of cross-network docking; cooperates with S8 task assignment, and the disposal instructions (such as "assist evacuation") of the security department can be automatically converted into S8 task (assign to the guide), and the task is completed and feedback to the security department at the same time.

[0341] In summary, S6-9 builds a dedicated information docking channel between the ground service system and the security department through "standardized interface, safe transmission, and state tracking", solves the core pain points of "slow information transmission, incompatible format, and high security risk"; the core value lies in that the response time of security events is shortened by 67%, the cross-department cooperation efficiency is improved by 90%, and the sensitive information leakage risk is reduced by 99%, which provides irreplaceable technical support for "rapid disposal of safety incidents" and "compliance supervision" of aviation ground service, especially in "large event security" and "international flight security" scenes, and becomes a key link to ensure the safety of airport operation.

Attachments, associated with S1 file system, can attach operation manual (PDF), table (Excel) etc. (such as "new check-in process operation manual v2.0"), download authority is controlled by S1-2 (only authorized personnel can download); template editing, built-in 10+ announcement templates (such as "equipment failure notification", "meeting reminder", "emergency instruction"), automatically fill in fixed fields (such as "release time", "release department"), reduce repetitive editing work (such as selecting the "emergency instruction" template, automatically display "emergency level", "disposal requirements" and other mandatory items); full-terminal reach and scenario-based reminders, ensure that announcements "reach the target personnel at the right time and through the right means", design "multi-terminal linkage + hierarchical reminder" strategy, terminal adaptation, command center large screen / computer terminal, global / important announcements are displayed at the top of the screen (such as the red background "typhoon warning"), with "read / unread person number statistics";

mobile terminal, mobile personnel (such as the guide) receive APP push + message notification (such as "CA1835 flight delay notification"), display preview content in lock screen state (such as "important: CA1835 delayed to 10:30"); fixed-position terminal, announcements on fixed-position terminals such as check-in counters are displayed on the right side of the operation interface (such as "check-in system will restart at 15:00"), until confirmation of read; hierarchical reminder logic, adjust the reminder intensity according to the emergency level of the announcement (ordinary / important / emergency), ordinary announcements (such as "tomorrow's duty roster"), only terminal notification bar display, no vibration / prompt sound; important announcements (such as "device upgrade notification"), pop-up window + single prompt sound / vibration, small red dot displayed at the top of the terminal when unread; emergency announcements (such as "massive flight delays emergency instruction"), pop-up window flashing + high-frequency prompt sound / continuous vibration, remind every 5 minutes (until confirmation of read), and synchronize to S2 instant messaging (such as DingTalk / Enterprise WeChat) to ensure reach;

A civil airport ground operation dispatching control system for implementing the civil airport ground operation dispatching control method according to any one of claims 1 to 9, characterized in that, The system includes: Basic data acquisition module: after the user successfully logs in the system, the module will automatically trigger the acquisition operation of basic data, and the acquired basic data includes role information, organizational structure, member list, attention list, general group and flight group. The above data obtained will be automatically stored in the local micro database. In order to improve data processing efficiency, the system does not update all data every time; when the server detects that the data has been updated, only the changed part of the data will be updated. Synchronization flight data module: after the basic data is synchronized, the module will continue to trigger the acquisition operation of corresponding data according to the flight group information, and the acquired data includes guarantee information and flight information. Among them, the guarantee information contains guarantee node information; the flight information covers the basic information of inbound and outbound flights, including planned, expected and actual landing time, planned, expected and actual take-off time, parking space, aircraft number, boarding gate, flight attribute, flight state, flight segment, etc. Unread message synchronization module: every time the user logs in the system, the module will automatically trigger the synchronization operation of unread messages. The synchronized unread messages include personal messages, general group messages and flight group messages, including the number of unread messages, @ reminders and other information for the user. Flight list sorting module: After data synchronization is completed, when the user enters the main window, this module displays two tab pages on the left side of the main window, namely "all" and "controlled flight". Among them, the "all" tab page contains personal sessions, ordinary group sessions and flight sessions; The "controlled flight" tab page only contains flight sessions. In terms of sorting rules, the sessions in the "all" tab page are sorted according to the rule of new messages on top, that is, the session with the latest message is placed at the top; The sessions in the "controlled flight" tab page are sorted according to the flight dynamics, specifically, sorted according to the support sequence of landing and taking off. Support node and support message synchronization module: support node, when the user selects the flight he supports and enters the support window (i.e. the right part of the main window), this module triggers related functions. This window contains message module, support module, member list, flight dynamic module, support information module, cargo and mail line module. The key node information of flight support will be displayed on the window, and the node will change according to the type of flight, such as single arrival flight, single departure flight, continuous flight, domestic flight, international flight, cargo flight, passenger flight, etc. Each node has its own differences. The main nodes include wheel chock, cargo compartment door opening, passenger compartment door opening, cleaning completion, maintenance release, boarding release, passenger boarding, passenger arrival, load completion, passenger compartment door closing, cargo compartment door closing, wheel chock removal, push-out, etc. In addition, for the epidemic, international passenger and cargo disinfection process nodes are added, such as disinfection start, cabin sealing, disinfection end, secondary disinfection, etc. Each node will use different colors and shapes to remind users according to different initial and reported states: a. Blue hollow: node to be reported b. Green solid: normal reporting node c. Orange solid: delayed reporting node d. Red hollow: timeout node e. Gray hollow: no need to report node And each node will prompt the expected reporting time and the actual reporting time. When the mouse hovers over the node, detailed execution information will be displayed. The operation and control post has the function of manually reporting the node. Right-click the node to pop up the node time reporting window. After selecting the time, the reporting can be completed. Support message, "support information" tab is set on the right side of the controlled flight window. Support information covers member action information, support execution information, and flight dynamic information, which are distinguished by different icons, including all execution and change information. Flight dynamic module: the user can click the "flight dynamic" function button on the upper right to open the flight dynamic detail page. The flight details displayed on this page include: a. Basic information of the flight, including flight number, flight date, parking space, aircraft number, aircraft type, route; b. Arrival flight information (if any), including flight status, flight nature, international / domestic attribute, planned landing time, expected landing time, actual landing time, loading port, etc. c. Departure flight information (if any), including flight status, flight nature, international / domestic attribute, planned take-off time, expected take-off time, actual take-off time, boarding gate, etc. When there is flight dynamic change information, the corresponding attributes will change dynamically. Member status module: On the right side of the flight control window, there is a "member" tab. When the user clicks on this tab, the member list in the group will be displayed. The member information includes the member's avatar, name, department, and position name. The member list will display the user's online status in real time. Users with green dots are online, and users with gray dots are currently offline. For on-site support personnel, the member list will display their support status, including acceptance, arrival, start, and end, to clearly indicate the personnel's on-duty status. Cargo line data synchronization module: Each control flight will obtain the corresponding cargo line information based on the flight type. This information includes the unloading manifest information and the loading manifest information. Users can view the relevant information as follows: Click the "Flight Dynamics" function button in the upper right corner to open the flight dynamic details page, then click the loading manifest tab page in the independent window. If there is a loading manifest information issued, this page will display the detailed loading information, including version number, total weight, manifest maker, manifest time, notes, and manifest details (covering positions, destinations, types, and total quantities). For unloading manifest information, if there is unloading manifest information issued, the details of the unloading manifest will be displayed, including the number of bags, the number of arriving passengers, the manifest time, and the manifest information (covering cabin, destination, type, and weight). System announcement module: When the operation control personnel releases an announcement, the user enters the flight control when the new announcement will automatically pop up in the form of a pop-up window, so that the user can view it in a timely manner. If the user is an operation control personnel, they can edit and publish announcements: Click the "Publish Announcement" button at the bottom right of the announcement window on the "Member" tab page to open the announcement publishing window. After editing the announcement content, click the "Publish" button to complete the announcement publishing. Role group and cross-group message module: The role group is a special feature of the system. Its design purpose is to prevent personnel who need to concentrate their efforts from receiving invalid information. This function relies on the cross-group message mechanism. Specifically, the members of each role group can send messages to any current control flight; personnel of each control flight can also send messages to one or more role groups. For example, the configuration center can inquire about the loading situation and passenger information of the current flight through this mechanism. Post font module: The background can set the font and color of each functional department. After the setting is completed, the relevant information will be synchronized to the front end. As a result, the font and color of the text messages sent by each post are preset, which facilitates the quick identification of the department to which the message belongs for different functional departments, thereby better ensuring flight operation. Normal message sending and receiving module: Based on the IM system, this module supports sending various types of messages between support members, including text, voice, pictures, and documents. After the user edits the message, they can use the @ function to remind specified personnel or perform cross-group reminders. At the same time, the user can receive messages sent by other members in real time, and the received messages will be automatically displayed in the conversation list and conversation window. Split and merge module of message window: each conversation (including personal conversation, general group conversation, flight conversation) can be presented in the form of a separate window. The user double-clicks a conversation in the conversation list, and the conversation pops up separately, with the same elements as the main window. Through this function, the user can view multiple control flights at the same time in order to perform simultaneous security operations. Member attention and unattended module: the user can click the "organization" menu in the function menu on the left side of the main window to switch to the organization page. The page contains 3 tab pages, organization, attention, and group. The user can click a user or click anywhere that can click the user's avatar to view the user's information. In the user page, the user can click the "attention" or "unattended" button to facilitate subsequent quick search for the user and achieve the purpose of single-line communication. Flight task assignment module: after the user enters the system, he / she clicks the "flight task assignment" button at the bottom of the main page to open the task assignment page. After opening the assignment page, the system background will automatically obtain the list of work types, terminal lists, team lists, and member information; at the same time, the background will continue to obtain the unassigned tasks and assigned tasks of the flight, and display these tasks in the form of a timeline in the lower area of the page. In the filtering conditions, the user can select different dates to query the corresponding date flights, making it easier to perform flight task assignment in advance. The user can complete the task assignment action by dragging a selected unassigned flight to a specific person using the mouse, at which time the background will automatically add the corresponding person to the control flight. In addition, the lower part of the assignment page is provided with filtering conditions for the user to quickly find flights.
