Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of airport automated baggage handling, in particular to a baggage dynamic recycling system and processing method based on real-time flight status. BACKGROUND

[0002] The baggage handling system (BHS) of a modern airport is a highly automated complex system, whose core goal is to efficiently and accurately transport passengers' checked baggage from the check-in counter to the correct flight loading area.

[0003] Under normal procedures, after security check and sorting, the baggage will be transported to the designated departure carousel (or baggage distribution area / slot) and wait for the ground staff to load the machine. In order to deal with the situation of passengers checking in advance, large airports usually have an early bag storage system (Early Bag Storage, EBS) to temporarily store the baggage that is still far from the flight departure time, and then automatically take it out from the EBS and send it to the departure carousel when the flight is approaching.

[0004] However, the existing technology has obvious process defects when dealing with "sudden and short" flight delays: when a flight is suddenly delayed (e.g. 1-3 hours) near the original departure time, and most of the corresponding baggage has been transported to the departure carousel, the following problems will arise: Problem one: occupying valuable departure carousel resources. The departure carousel is one of the bottleneck resources of the airport baggage handling system. A large number of delayed baggage occupying one or more carousels for a long time will cause the baggage of subsequent normal flights to be unable to be allocated to the carousel in time, causing systematic congestion and seriously affecting the overall operational efficiency of the airport; Problem two: relying on inefficient and high-risk manual intervention. In order to alleviate the pressure on the carousel, the current solution is to manually move these delayed baggage from the carousel by ground staff, and then use the baggage cart to stack it in a temporary area. This operation method has many disadvantages: high labor cost: a large number of ground staff need to be invested to do heavy physical labor; low efficiency: the speed of manual handling and recording is far lower than that of automated systems; high risk: during the process of handling, stacking and re-sorting, it is easy to cause the wrong taking, missing and damage of baggage, causing losses to passengers and airlines; potential safety hazards: manually handling a large number of heavy baggage poses a potential threat to the health of the operators.

[0005] Therefore, the existing technology lacks a solution that can automatically, quickly and reliably respond to sudden flight delays and effectively manage sorted baggage. SUMMARY

[0006] To address the aforementioned issues, the present invention aims to provide a baggage dynamic recirculation technology based on real-time flight status. This technology automatically and intelligently retransports baggage that has arrived at the departure carousel area and stores it in the Early Baggage Storage System (EBS) or other storage systems (such as queue conveyor buffers) based on real-time flight delay information. This instantly releases departure carousel resources, avoids manual intervention, and improves the automation level and operational efficiency of the entire baggage handling system.

[0007] To achieve the above technical objectives, this application provides a baggage dynamic recirculation system based on real-time flight status, comprising: The real-time flight information interface module is used to continuously monitor the status of all flights; The baggage location tracking and identification module is used to track the precise physical location of each piece of baggage in the delivery system in real time; The central control module receives and analyzes flight status change information; when a critical delay event is detected, it calls the baggage location tracking and identification module to obtain all baggage belonging to the corresponding flight and already arrived at the departure carousel area; it makes a "reverse flow" decision and plans the optimal physical path for these baggage to return from their current location to the Early Baggage Storage System (EBS); at the same time, it generates and sends control commands to the execution mechanism of the Baggage Handling System (BHS). The path execution and feedback module is used to receive and execute instructions from the central control module.

[0008] Preferably, the real-time flight information interface module is used to continuously monitor the status of all flights by accessing and parsing data from the airport flight information system data source in real time.

[0009] Preferably, the baggage location tracking and identification module is used to track the precise physical location of each piece of baggage in the transport system in real time using the baggage handling system (BHS).

[0010] Preferably, the path execution and feedback module is used to control the hardware equipment of BHS, guide the target baggage to enter EBS along the planned path, and at the same time, feed back the real-time location of the baggage to the central control module to form a closed-loop control.

[0011] Based on the aforementioned baggage dynamic recirculation system based on real-time flight status, this invention further provides a baggage dynamic recirculation processing method, comprising the following steps: Step S1: Monitoring and Triggering: When monitoring flight dynamics, if the status of a flight changes from "normal" to "delayed" and the delay time exceeds a preset threshold, a re-processing instruction will be automatically triggered. Step S2: Target baggage identification and location: In response to the command trigger, based on the delayed flight number, retrieve all associated baggage information in the BHS baggage database and lock baggage whose physical location is in the "departure carousel area" as the target processing object; Step S3: Decision-making and reverse route planning: After the central control module confirms the target baggage list, the reverse route planning algorithm is started to calculate the optimal, conflict-free transport route from the departure carousel area back to the EBS entrance. Step S4: Execute reverse transport: After decomposing the route instructions into a series of control commands for the BHS hardware and issuing the commands, start the reverse transport process to send the target baggage back from the departure carousel. Step S5: Storage and Information Update: After entering EBS, baggage is stored according to standard procedures, and its status is updated. Preferably, when performing target baggage identification and location, based on the baggage source information (BSM) generated during self-check-in, all related baggage information is retrieved from the BHS baggage database.

[0012] Preferably, when performing target baggage identification and positioning, the area associated with the departure carousel or chute is defined as the "departure carousel area" by a physical range pre-defined in the system.

[0013] Preferably, when performing warehousing and information updates, the updated baggage status is marked as "temporarily stored due to delay".

[0014] The present invention discloses the following technical effects: This invention achieves complete automation and eliminates human intervention: it transforms the manual handling work that originally required a lot of manpower into a fully automated system process, fundamentally solving the problems of inefficiency, high cost and high risk caused by manual operation.

[0015] This invention greatly improves resource utilization: it can quickly clear departure carousels occupied by delayed baggage in a short period of time, freeing them up for subsequent regular flights, effectively avoiding system congestion and significantly improving the airport's baggage handling capacity during peak hours.

[0016] This invention improves the accuracy and security of baggage handling: baggage is processed in a fully automated, traceable closed-loop system, avoiding the loss, missorting, and damage that may occur with manual handling, thus ensuring the safety of passengers' property.

[0017] This invention enhances the flexibility and intelligence of airport operations: it makes the airport baggage system "resilient" and "intelligent" in responding to emergencies, and is an important part of building a smart airport. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] like Figures 1-2 As shown, this invention provides a baggage dynamic recirculation system based on real-time flight status. This system is integrated with the airport's existing baggage handling system (BHS) and early baggage storage system (EBS), and its core components include: 1. Real-time flight information interface module: Used to access and parse data from the airport flight information system in real time, and continuously monitor the status of all flights (such as delays, cancellations, gate changes, etc.).

[0022] 2. Baggage location tracking and identification module: Utilizing barcode readers or RFID (Radio Frequency Identification) readers, video, low-end control, and other methods already deployed in BHS, the precise physical location of each piece of baggage in the transportation system can be tracked in real time.

[0023] 3. Central Control Module: This module integrates the core control logic and algorithms, and is responsible for: Receive and analyze flight status change information.

[0024] When a critical delay event is detected, the baggage tracking module is immediately invoked to identify all baggage belonging to that flight that has arrived at the departure carousel area.

[0025] It automatically makes "reverse flow" decisions and plans the optimal physical path for these bags to return to EBS from their current location.

[0026] Generate and issue control commands to the actuators of the BHS (such as conveyor belt motors, diversion equipment, etc.).

[0027] 4. Route Execution and Feedback Module: This module receives and executes instructions from the central control module, controls the BHS hardware (e.g., drives the "return" device), and guides the target baggage along the planned route into the EBS. Simultaneously, it feeds back the real-time location of the baggage to the central control module, forming a closed-loop control system.

[0028] The system of the present invention can be implemented as an upgrade software module of the existing BHS central controller, or it can be implemented as a standalone server that communicates with BHS, EBS and airport flight information system data sources through standard interfaces.

[0029] Regarding the systems mentioned above, such as Figure 2 As shown, the present invention also provides a corresponding method for dynamic baggage recycling, which specifically includes the following steps: Step S1: Monitoring and Triggering: The system monitors flight dynamics 24 / 7 through the flight information interface module. When the status of a flight changes from "normal" to "delayed" and the delay time exceeds a preset threshold (e.g., 30 minutes), a re-processing instruction is automatically triggered.

[0030] Step S2: Target Baggage Identification and Location: Upon command triggering, the system immediately retrieves all associated baggage information (usually from baggage source information BSM generated during check-in) from the BHS baggage database based on the delayed flight number. Simultaneously, the baggage location tracking module is invoked to identify baggage whose current physical location is in the "departure carousel area" (which can be an area associated with the departure carousel or chute, a pre-defined physical range in the system) as the target for processing.

[0031] Step S3: Decision-making and reverse route planning: After the central control module confirms the target baggage list, it immediately starts the reverse route planning algorithm to calculate the optimal, conflict-free transport route from the departure carousel area back to the EBS entrance.

[0032] Step S4: Execute reverse transport: The system decomposes the path instructions into a series of control commands for the BHS hardware, issues them through the path execution module, controls the corresponding conveyor belts, sorting machines and other equipment, starts the reverse transport process, and sends the target baggage back from the departure carousel one by one in an orderly manner.

[0033] Step S5: Storage and Information Update: After baggage enters EBS, it is stored according to standard procedures. At the same time, the system updates the status and location information of this baggage and marks it as "temporarily stored due to delay".

[0034] In practice, the delay time threshold in step S1 can be flexibly set by the airport management based on actual operating conditions (such as airport busyness and the tightness of carousel resources).

[0035] In step S2, the physical area of ​​the "departure carousel area" can be defined by delineating a set of RFID readers or barcode scanners' IDs in the system. Any baggage belonging to a delayed flight that is read by these devices will be considered target baggage.

[0036] In step S4, some key links in the BHS system are designed with reserved "return channels" or additional "return channels" to facilitate the implementation of the present invention. These "return channels" can be channels composed of unidirectional conveyors or channels composed of bidirectional conveyors.

[0037] In summary, this invention, through innovative control logic and methods, cleverly utilizes and expands the functionality of existing airport hardware facilities (BHS and EBS), solving a long-standing pain point in airport operations through "reverse baggage flow," and has high practical value and promising prospects for promotion.
