Description

Technical Field

[0001] This application relates to the field of network management technology, and more specifically, to a comprehensive cabling management system and method. Background Technology

[0002] With the rapid development of the digital economy, data centers are expanding on a large scale, and network architectures are evolving towards flatter, cloud-based structures. As the "nerve center" of communication networks, structured cabling is experiencing exponential growth in scale and complexity. Traditional structured cabling systems rely on manual records (such as Excel spreadsheets and paper ledgers) and static labels (such as paper labels and inkjet labels) for management, which is no longer suitable for the operation and maintenance needs of modern networks. Specifically, the following prominent problems exist: 1. The connection relationship is opaque and lagging: the insertion and removal of port patch cords, link changes and other operations rely entirely on manual recording. The change information cannot be synchronized in real time, resulting in inconsistencies between the ledger and the actual wiring status. When troubleshooting, each segment needs to be checked, which is extremely inefficient. 2. High risk and low efficiency of manual maintenance: A single data center may deploy thousands of fiber optic ports. Manual inspection and patching operations are prone to problems such as incorrect connections, omissions, and label detachment. According to industry statistics, under the traditional manual management model, cabling faults account for more than 35% of the total number of network faults, and the mean time to repair (MTTR) exceeds 4 hours. 3. Insufficient granularity in resource management: The inability to monitor key data such as port occupancy, link load, and patch cord aging status in real time leads to both idle and overloaded resources, making it difficult to achieve dynamic optimization and configuration of cabling resources; 4. Poor system interoperability: Isolated from existing Network Management System (NMS), Data Center Infrastructure Management System (DCIM), and Asset Management System (AMS), forming information silos and making it impossible to achieve cross-system data sharing and collaborative operation and maintenance; 5. Existing intelligent solutions have shortcomings: Current intelligent patch panel solutions use external sensing modules (such as independent patch cord sensors and external detection boxes) or distributed control structures (multiple modules deployed in a decentralized manner), which have defects such as low system integration, complex deployment process (requiring additional wiring to install sensing modules), high maintenance cost (prominent module compatibility issues), and response delay (long distributed communication links). They are difficult to meet the core requirements of modern data centers for high reliability (MTBF≥100,000 hours), low latency (status detection response≤100ms), and intelligent operation and maintenance. Summary of the Invention

[0003] This invention provides a structured cabling management system to solve the technical problems described in the background section of the prior art. The structured cabling management system includes: The perception layer is used to collect the status information of the fiber optic cabling in real time and send the status information to the access layer. The status information includes physical status and basic parameters. The access layer is used to preprocess the state information of the perception layer and send it to the management layer, and to send downlink instructions issued by the management layer to the perception layer. The management layer is used to build a full cabling resource database, generate alarm information and statistical data based on preprocessed status information, and forward the status information, alarm information and statistical data to the application layer, and forward the downlink commands from the application layer to the management layer. The application layer is used to display status information and statistical data in real time, and to send downlink instructions to the application layer based on alarm information; A communication network is used to support data transmission between the perception layer, access layer, management layer, and application layer.

[0004] In some embodiments of this application, the sensing layer is specifically an integrated intelligent fiber optic distribution subframe, which includes: Fiber optic port module with built-in ceramic sleeve, and provides single-mode or multimode fiber adapter; The port status sensing module corresponds one-to-one with each fiber optic port of the fiber optic port module. It includes an infrared sensing unit and a data preprocessing unit. The infrared sensing unit is used to detect jumper insertion and removal actions based on infrared sensors. The data preprocessing unit is used to filter, amplify and perform AD conversion on the status information and output a standardized digital signal. The port indicator module is equipped with an infrared LED indicator to indicate the connection status of the port based on the mode of the infrared LED indicator. The modes of the infrared LED indicator include always off mode, always on mode and flashing mode. The patch panel body has a built-in microcontroller unit, adopts a 19-inch standard rack-mount design, and is made of cold-rolled steel plate with an anodizing process. The microcontroller unit is used to send the status information output by the port status sensing module to the access layer, and is connected one-to-one with the infrared LED indicator in the port indicator module through the PWM control port to directly output the on / off / flashing control signal. The power supply module is used to supply power to other modules within the perception layer.

[0005] In some embodiments of this application, the access layer is specifically a patch panel management unit, which includes: An embedded processor is used to preprocess the state information; The data interface module is used to receive status information sent by the perception layer, forward downlink instructions issued by the management layer to the perception layer, and send the status information preprocessed by the embedded processor to the management layer. The local storage module is used to automatically store data entering the access layer; The alarm module is used to preset alarm thresholds, identify abnormal events based on the alarm thresholds, and issue alarms. The power supply module is used to supply power to other modules in the access layer.

[0006] In some embodiments of this application, the management layer specifically includes: Server hardware nodes are used to form a cluster with other server hardware nodes via high-speed Ethernet. Database clusters are used to connect to server hardware nodes through a dedicated storage network to achieve distributed storage and high-speed caching of tens of millions of data entries. The calculation module is used to analyze the preprocessed status information sent by the access layer and generate alarm information and statistical data. The middleware module is used to forward data sent between the computing module and the interface module; The interface module includes a standardized communication interface and an internal communication interface. It connects to the external and internal computing modules via Ethernet. The standardized communication interface is used to receive status information from the access layer, downlink commands from the application layer, and integration commands from third-party systems. The internal communication interface is used to establish connections with the computing modules of each node to achieve bidirectional data transmission.

[0007] In some embodiments of this application, the application layer specifically includes a PC terminal, a mobile terminal, and a Web-based operation and maintenance management platform. The application layer is used to perform visual management of information in the integrated cabling management system and to issue downlink commands in response to user operations.

[0008] Accordingly, the present invention also proposes a structured cabling management method, characterized in that the method is applied to a structured cabling management system as described above, and the method includes: Deploy and establish communication connections with the integrated cabling management system, and perform initial configuration of the integrated cabling management system; The status information of the fiber optic cabling is collected in real time by the perception layer and uploaded to the access layer. The access layer preprocesses the status information and forwards the preprocessed status information to the management layer. Based on the management layer's parsing of the preprocessed status information, the port status is determined, and based on preset rules, it is judged whether there are any abnormal events. If there are any abnormal events, alarm information is generated and forwarded to the application layer. After receiving the alarm information at the application layer, maintenance operations are performed based on the alarm information.

[0009] In some embodiments of this application, the integrated cabling management system is deployed and connected for communication, and the integrated cabling management system is initialized and configured, specifically as follows: Build the system hardware architecture and complete the deployment and communication connection of integrated intelligent fiber optic distribution subframes, distribution frame management units, servers, and management terminals; Import basic resource information through the management terminal. The basic resource information includes physical location information, equipment information, and link planning information. Establish resource mapping relationships, including mapping between ports and physical locations, mapping between ports and devices, and mapping between preset links and ports; Configure system parameters, including the detection cycle of the sensing module, alarm threshold, communication protocol, third-party interface parameters, and user permissions.

[0010] In some embodiments of this application, the step of collecting the status information of the optical fiber cabling in real time through the sensing layer, uploading the status information to the access layer, preprocessing the status information through the access layer, and forwarding the preprocessed status information to the management layer specifically involves: The port status sensing module of the integrated intelligent fiber optic distribution subframe collects port plug-in / plug-out status and link attenuation values ​​according to the configuration cycle. The embedded control module filters and encrypts the collected port plug-in / plug-out status and link attenuation values ​​to generate standardized data frames. Standardized data frames are uploaded to the patch panel management unit via the communication network. After the patch panel management unit aggregates and preprocesses the data from multiple sub-frames, it is uploaded to the integrated cabling management server. If communication is interrupted, the subrack caches the data locally, the management unit stores the aggregated data, and the transmission is automatically resumed after communication is restored.

[0011] In some embodiments of this application, the port status is determined by parsing the preprocessed state information by the management layer, and the existence of abnormal events is judged based on preset rules. If an abnormal event exists, an alarm message is generated and forwarded to the application layer. Specifically: Based on the structured cabling management server, the data frames are decrypted and parsed to update the port status, link status, and environment status in the resource database; Determine if the port status has changed; if so, record the change information. Based on preset rules, determine whether it is an illegal change; if so, mark it as an abnormal change and trigger an alarm. The server generates alarm information according to the configured alarm level based on the status judgment result.

[0012] In some embodiments of this application, after the application layer receives the alarm information, maintenance operations are performed based on the alarm information, specifically as follows: Send alarm notifications to designated maintenance personnel via terminal devices; Maintenance personnel receive alarm information through the management terminal. After confirming the alarm, the system records the confirmation time. Maintenance personnel go to the site to handle the fault. After the fault is handled, they submit the handling result on the management terminal. The system updates the alarm status to "closed loop" and records the handling process.

[0013] By applying the above technical solutions, the integrated cabling management system includes: a perception layer, used to collect real-time status information of fiber optic cabling and send the status information to the access layer, the status information including physical status and basic parameters; an access layer, used to preprocess the status information from the perception layer and send it to the management layer, and send downlink commands issued by the management layer to the perception layer; a management layer, used to generate alarm information and statistical data based on the preprocessed status information, and forward the status information, alarm information, and statistical data to the application layer, and forward downlink commands from the application layer to the management layer; an application layer, used to display the status information and statistical data in real time, and send downlink commands to the application layer based on alarm information; and a communication network, used to support data transmission between the perception layer, access layer, management layer, and application layer, thereby providing a highly integrated, accurate, intelligent, and compatible integrated cabling management system, improving the accuracy and efficiency of cabling management.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] This application provides a comprehensive cabling management system, such as... Figure 1 As shown, the integrated cabling management system includes: The perception layer is used to collect the status information of the fiber optic cabling in real time and send the status information to the access layer. The status information includes physical status and basic parameters. The access layer is used to preprocess the state information of the perception layer and send it to the management layer, and to send downlink instructions issued by the management layer to the perception layer. The management layer is used to generate alarm information and statistical data based on the preprocessed status information, and forward the status information, alarm information and statistical data to the application layer, and forward the downlink commands from the application layer to the management layer; The application layer is used to display status information and statistical data in real time, and to send downlink instructions to the application layer based on alarm information; A communication network is used to support data transmission between the perception layer, access layer, management layer, and application layer.

[0018] In some embodiments of this application, the sensing layer is specifically an integrated intelligent fiber optic distribution subframe, which includes: Fiber optic port module with built-in ceramic sleeve, and provides single-mode or multimode fiber adapter; The port status sensing module corresponds one-to-one with each fiber optic port of the fiber optic port module. It includes an infrared sensing unit and a data preprocessing unit. The infrared sensing unit is used to detect jumper insertion and removal actions based on infrared sensors. The data preprocessing unit is used to filter, amplify and perform AD conversion on the status information and output a standardized digital signal. The port indicator module is equipped with an infrared LED indicator to indicate the connection status of the port based on the mode of the infrared LED indicator. The modes of the infrared LED indicator include always off mode, always on mode and flashing mode. The patch panel body has a built-in microcontroller unit, adopts a 19-inch standard rack-mount design, and is made of cold-rolled steel plate with an anodizing process. The microcontroller unit is used to send the status information output by the port status sensing module to the access layer, and is connected one-to-one with the infrared LED indicator in the port indicator module through the PWM control port to directly output the on / off / flashing control signal. The power supply module is used to supply power to other modules within the perception layer.

[0019] Specifically, such as Figure 2 As shown, the perception layer: its core is an integrated intelligent fiber optic distribution subframe, which is responsible for the collection and local preprocessing of port status, link parameters, and environmental data; The core of the sensing layer is an integrated intelligent fiber optic distribution subframe, which contains five core components: the distribution frame body, fiber optic port module, port status sensing module, port indicator module, and power supply module. All components are integrated and embedded, requiring no external cabling. The specific connection relationships are as follows: 1. Physical carrier: All modules are embedded in the standardized slots / cavities of the patch panel body, and are fixed and physically connected through the internal metal back plate; 2. Electrical connection: The power supply module provides unified power to the port status sensing module and port indication module through the internal DC bus, and the built-in overvoltage / overcurrent protection circuit is connected in series in the power supply link; 3. Data connection: Each fiber optic port module is hard-connected one-to-one with the corresponding port status sensing module. The output of the sensing module is aggregated to the microprocessor unit built into the subrack via the internal SPI / I2C bus. The microprocessor unit then communicates with the outside (access layer) via the Ethernet / RS485 interface. 4. Control Connection: The microprocessor unit is connected one-to-one with the port indicator module (red LED) through the PWM control port, and directly outputs the on / off / blinking control signal.

[0020] The perception layer is the lowest-level raw data acquisition and local preprocessing unit of the system. It is the "sensory tentacles" of the entire cabling management system. Its core function is to collect the physical status and basic parameters of the fiber optic cabling in real time, and output standardized digital signals after completing local primary processing.

[0021] The sensing layer is directly connected to the access layer only, with no direct connection across layers. The connection method is wired (Ethernet, RS485 bus). A single access layer (patch panel management unit) can connect to an integrated intelligent fiber optic patch panel of up to 24 sensing layers, with star / bus topology connections.

[0022] Specifically, the integrated intelligent fiber optic distribution subframe is the core sensing unit of the system, adopting an integrated sealed design (IP45 protection level), such as... Figure 7 As shown, the built-in modular components specifically include: 1. Patch panel body: Adopts 19-inch standard rack design, supports 3U / 4U / 5U height specifications, adapts to various types of fiber optic ports such as LC / SC / FC, and offers optional port densities of 48 / 72 / 96 ports. The body is made of cold-rolled steel plate with anodizing process, which has anti-electromagnetic interference, dustproof and heat dissipation performance. 2. Fiber optic port module: Each port is independently designed with a built-in ceramic sleeve (insertion loss ≤0.2dB) and supports single-mode / multimode fiber adaptation; 3. Port Status Awareness Module: Corresponding one-to-one with each fiber optic port, employing an "optical coupler sensing" design, including: Infrared sensing unit: Based on infrared sensors, it detects jumper insertion and removal actions with a response time of ≤50ms; Data preprocessing unit: filters, amplifies, and performs AD conversion on the status information, and outputs a standardized digital signal; 4. Port Indicator Module: Each port is equipped with a red LED indicator, supporting two modes: always off, always on, and flashing. Specific indication rules are as follows: Always off: The port connection status is normal; Flashing: The port is in jumper operation boot state; Constant light: Port connection status error.

[0023] 5. Power Supply Module: Supports dual redundant power supply, adaptable to input voltage range of 9-24V DC or PoE power supply (IEEE802.3af / at standard), built-in overvoltage, overcurrent, and short circuit protection circuits, output voltage stability ±5%, standby power consumption 0.5W, full load power consumption ≤1.5W. In some embodiments of this application, the access layer is specifically a patch panel management unit, which includes: An embedded processor is used to preprocess the state information; The data interface module is used to receive status information sent by the perception layer, forward downlink instructions issued by the management layer to the perception layer, and send the status information preprocessed by the embedded processor to the management layer. The local storage module is used to automatically store data entering the access layer; The alarm module is used to preset alarm thresholds, identify abnormal events based on the alarm thresholds, and issue alarms. The power supply module is used to supply power to other modules in the access layer.

[0024] Specifically, the access layer, namely the patch panel management unit, is responsible for the aggregation of data from the perception layer, protocol conversion, and command issuance. The core of the access layer is the patch panel management unit, an industrial-grade integrated device. Internally, it contains five core components: an embedded processor (STM32F103 / ARM Cortex-A9 / ESP32), a data interface module, a local storage module, an alarm module, and a power supply module. All components are integrated and soldered onto the board, representing an industrial-grade control board design. Figure 3 As shown, the specific connection relationships are as follows: Core control: The embedded processor is the core of the unit, and all modules are directly connected to the processor through the onboard bus (address bus / data bus / control bus); Data Interface: The data interface module (Ethernet / RS485 / CAN) connects to the processor via an onboard interface, serving as a communication bridge with the perception / management layer; Storage connectivity: The local storage module (32GB) is connected to the processor board via a SATA / SD interface to enable local data caching; Alarm Connection: The alarm module (buzzer + local indicator light) is connected to the processor one-to-one via GPIO ports to receive alarm control signals; Power supply connection: The power supply module provides unified power to all onboard components, with a built-in power conversion circuit that is compatible with industrial-grade voltage input.

[0025] The access layer is a "data relay station + local processing hub" between the system perception layer and the management layer. Its core function is to aggregate data from multiple perception layer nodes, complete standardized preprocessing, and then upload it to the management layer. At the same time, it forwards downlink instructions from the management layer to the perception layer and realizes local fault alarms and breakpoint resume. It is a key bridge connecting the lower-level perception layer and the upper-level hub.

[0026] The access layer is directly connected to the perception layer and the management layer, serving as a connection node across two layers, but has no direct connection to the application layer.

[0027] Specifically, the patch panel management unit, as a core device of the access layer, adopts an industrial-grade design (operating temperature -40~85℃) and can be implemented using a microcontroller (such as STM32F103), embedded processor (such as ARM Cortex-A9), or SoC chip (such as ESP32). It supports managing 24 integrated intelligent fiber optic patch panels per unit, and its specific functions include: 1. Data aggregation and preprocessing: Receive port status and environmental data uploaded from multiple patch panels via bus or Ethernet, perform data deduplication and format standardization (JSON / Protobuf protocol) to reduce the load on the management server; 2. Command forwarding and control: Receive control commands from the structured cabling management server (such as port indicator light control and patch cord guidance commands) and send them to the corresponding patch panel; 3. Local caching and resume interrupted download: Configure 32GB of local storage to cache critical data within 24 hours. When communication with the management layer is interrupted, the data is automatically stored, and resumed download after communication is restored. 4. Local alarm and linkage: Preset alarm thresholds (such as abnormal port plugging / unplugging). When an abnormality is detected, an alarm can be triggered via a local buzzer and indicator light. 5. Equipment management function: Supports online upgrades, parameter configuration (such as sensing module detection thresholds and communication cycles) and status inspections of subordinate wiring subracks to achieve remote maintenance.

[0028] In some embodiments of this application, the management layer specifically includes: Server hardware nodes are used to form a cluster with other server hardware nodes via high-speed Ethernet. Database clusters are used to connect to server hardware nodes through a dedicated storage network to achieve distributed storage and high-speed caching of tens of millions of data entries. The calculation module is used to analyze the preprocessed status information sent by the access layer and generate alarm information and statistical data. The middleware module is used to forward data sent between the computing module and the interface module; The interface module includes a standardized communication interface and an internal communication interface. It connects to the external and internal computing modules via Ethernet. The standardized communication interface is used to receive status information from the access layer, downlink commands from the application layer, and integration commands from third-party systems. The internal communication interface is used to establish connections with the computing modules of each node to achieve bidirectional data transmission.

[0029] Specifically, the management layer includes the structured cabling management server and its supporting database and middleware, which are responsible for data storage, logical operations, resource scheduling, and system integration. The core of the management layer is a structured cabling management server, employing a distributed architecture that can be deployed as a single machine or in a cluster. Internally, it comprises five core components: server hardware nodes, a database cluster, middleware modules, interface modules, and a computing module. These components are interconnected via network-level software and hardware, supporting deployment on physical servers and cloud platforms. Figure 4 As shown, specifically: Server clusters: These provide the hardware support for the management layer, handling operations, computation, and storage, including memory, processors, and hard drives—essentially, servers. Distributed scaling is used to expand computing power and storage when there are many nodes, a large workload, and a high volume of concurrent requests. When demand is low, a single server is sufficient. The database cluster consists of a MySQL master-slave cluster and a Redis cache cluster. The MySQL cluster is used for persistent storage of structured data (including tens of millions of data entries such as cabling asset ledgers, link topology information, configuration parameters, and historical logs), while the Redis cluster is used for caching hot data (such as real-time link status, session information, and high-frequency query results). This achieves read-write separation, high-speed access, and cache penetration protection, while ensuring data consistency and high availability through master-slave replication and sharding strategies. The computation module performs core logic operations, including link connectivity verification, asset conflict detection, configuration change compliance verification, alarm threshold judgment, and permission authentication. The computation results are written back to the database cluster for persistent storage, and the processing status and results are synchronized to the middleware module. Middleware module: Receives external request data forwarded by the interface module, performs data format conversion, protocol parsing, and permission filtering, and distributes it to the corresponding computing module according to business type; at the same time, it receives the processing results returned by the computing module, encapsulates and routes the data according to the protocol specifications of the target interface, and forwards it to the interface module; through traffic control, session management, and exception retry mechanisms, it ensures the stability and reliability of data interaction between the computing module and the interface module. Interface module: Used to receive status data collected from access layer devices, business operation requests from application layer, and integration instructions from third-party systems; internal communication interface is used to establish connections with the computing modules of each node to achieve bidirectional data transmission; specifically, it forwards external data to the middleware module after protocol parsing and preprocessing, and at the same time receives the processing results returned by the middleware module, encapsulates them into a response format that conforms to the external system specifications and returns them, thus completing the closed loop of business data transmission and reception.

[0030] The management layer is the "core hub" of the entire system, undertaking the core functions of data storage, logical operation, resource scheduling, system linkage, and full-process management. It is the key to realizing intelligent cabling management. Its core role is to perform in-depth processing of the aggregated data uploaded by the access layer, build a full-scale cabling resource database, realize change tracing, alarm management, statistical analysis, and complete seamless integration with third-party systems. At the same time, it pushes processing results to the application layer and receives application layer instructions.

[0031] The management layer is directly connected to the access layer and application layer, and can also seamlessly interface with third-party systems, serving as the core connection hub of the system.

[0032] Specifically, the structured cabling management server is the core of the management layer. It receives all the sensing data uploaded by the access layer through the communication network, processes it, and then sends the calculation results and control commands back to the access layer via the communication network. Simultaneously, it pushes real-time status, alarm information, and statistical data to the application layer through the communication network and receives manual operation commands from the application layer. It can also achieve standardized data interaction with third-party management systems through the communication network. It is the data processing hub, command scheduling hub, and resource management hub of the entire system. The system architecture is as follows: Figure 1 As shown.

[0033] The structured cabling management server adopts a distributed architecture design, supports single-machine or cluster deployment, and can be deployed on physical servers or cloud platforms (public cloud / private cloud). Specific functions include: 1. Resource Information Management: Establish a full-scale cabling resource database (using MySQL cluster + Redis cache, supporting data storage of tens of millions of records), storing port information (ID, type, location, device), link information (start point, end point, length, attenuation threshold), device information (patch panel, switch, server, etc.), and patch cord information (ID, model, laying path, service life). Supports resource import / export (Excel / CSV format), batch editing, and historical version rollback (retains resource change records within 6 months); 3. Change Management and Tracking: Real-time monitoring of port status changes (plugging / unplugging, link attenuation changes), automatic recording of change information (change time, operator, status before and after change), and generation of change logs; Supports change approval process (configure work order review node), and automatically triggers alarms and records operation trajectory for illegal changes (jump operation that has not passed approval); 4. Alarm Management: It supports multi-dimensional alarm configuration (port disconnection, link attenuation exceeding the limit, environmental anomaly, communication interruption, etc.), and the alarm level is divided into four levels: emergency, important, general, and warning. 5. Statistical Analysis and Reports: Automatically calculates key indicators such as cabling resource utilization (port occupancy rate, link load rate), failure rate, and maintenance work order completion rate, and supports generating statistical reports by day / week / month / year; It provides trend analysis functions (such as link attenuation trend and resource utilization growth trend) to provide data support for cabling expansion and optimization. 6. Integration with third-party systems: It provides standardized interfaces to support data synchronization and collaboration with network management systems (NMS, supporting SNMPv3 protocol) and work order systems (supporting API integration); It supports two-way data interaction, such as receiving device status information from NMS, pushing patch panel environment data to DCIM, and automatically generating maintenance work orders to the work order system; 7. System Management: Supports hierarchical user permission management (administrators, operations and maintenance personnel, viewers, etc.), and refines operation permissions (such as configuration modification permissions, alarm handling permissions, and report export permissions). It provides system log auditing (records all user operations and system running status), data backup and recovery (automatic backup + manual backup, supports off-site backup), and system upgrade (online upgrade / offline upgrade) functions.

[0034] In some embodiments of this application, the application layer specifically includes a PC terminal, a mobile terminal, and a Web-based operation and maintenance management platform. The application layer is used to perform visual management of information in the integrated cabling management system and to issue downlink commands in response to user operations.

[0035] In this embodiment, as Figure 5 As shown, the application layer, i.e. the management terminal, provides a visual operation interface and access to operation and maintenance functions.

[0036] The core of the application layer is the management terminal, which serves as the system's human-computer interaction entry point. It supports multi-terminal adaptation and internally includes three main terminal types: PC terminals, mobile terminals, and a web-based operations and maintenance management platform. Each terminal uses a distributed software / hardware connection based on the management layer server, without direct physical hardware connection. Figure 7 As shown, data synchronization is achieved through the network.

[0037] Core reliance: All terminals use the management server as the data core, obtaining real-time data from the server and uploading operation instructions to the server via the network; Inter-terminal synchronization: The operation data and status data of each terminal are synchronized in real time through the management server to ensure data consistency across multiple terminals; Local adaptation: Each terminal has its own dedicated software modules (PC client, mobile APP, web front-end) built in according to its own hardware characteristics to achieve functional adaptation and interface visualization.

[0038] The application layer is the "final execution and display end" of the system, and it only has a direct collaborative relationship with the management layer. The two have a subordinate relationship of "interaction end - central end", and it serves as a bridge between manual operation and the implementation of system functions. The application layer is directly connected to the management layer only, without any cross-layer direct connection to the access layer / perception layer. The connection method is wired (Ethernet) / wireless (Wi-Fi) optional. It is based on the TCP / IP protocol, supports distributed concurrent connection of multiple terminals (PC / mobile / WEB), and is compatible with display devices of different resolutions (computers, tablets, mobile phones).

[0039] The system supports wired (Ethernet, RS485 bus) or wireless (Wi-Fi) communication between different levels, allowing for flexible selection based on the deployment scenario.

[0040] Data export and backup module: Supports local export of log data in formats such as Excel and PDF, has a scheduled automatic backup function to back up important data to external storage media to prevent data loss due to equipment failure, and also supports a cyclic overwrite storage strategy.

[0041] Specifically, the management terminal, as the application layer interaction entry point, supports multi-terminal adaptation, including: 1. PC Terminal: Client software based on Windows / Linux / Mac OS systems, with the following functionalities: Visual management: topology diagram display, resource list query (supports multi-condition filtering), and real-time port status refresh (refresh frequency can be configured: 1s / 5s / 10s).

[0042] In some embodiments of this application, the intelligent barrier gate control module includes two working modes: automatic and manual. In automatic mode, the barrier gate is automatically opened or closed according to control commands. The manual mode is applied to special scenarios, including emergency passage and equipment debugging, and records the time, operator, and reason for all barrier gate actions.

[0043] In addition, the communication network is used to realize data transmission between the perception layer, access layer, management layer, and application layer, and supports the following types and combinations: 1. Wired communication: Ethernet: Supports TCP / IP protocol, suitable for fixed deployment scenarios such as data centers and computer rooms, with a transmission rate of 100M / 1000M and a transmission distance of ≤100m (Category 5e cable) or ≤10km (fiber optic cable).

Communication protection mechanism: Data encryption transmission (TLS 1.3 protocol), retransmission mechanism (configurable number of timeout retransmissions), and load balancing (multi-link redundancy) are adopted to ensure the security and reliability of data transmission.

[0044] By applying the above technical solutions, the integrated cabling management system includes: a perception layer, used to collect real-time status information of fiber optic cabling and send the status information to the access layer, the status information including physical status and basic parameters; an access layer, used to preprocess the status information from the perception layer and send it to the management layer, and send downlink commands issued by the management layer to the perception layer; a management layer, used to generate alarm information and statistical data based on the preprocessed status information, and forward the status information, alarm information, and statistical data to the application layer, and forward downlink commands from the application layer to the management layer; an application layer, used to display the status information and statistical data in real time, and send downlink commands to the application layer based on alarm information; and a communication network, used to support data transmission between the perception layer, access layer, management layer, and application layer, thereby providing a highly integrated, accurate, intelligent, and compatible integrated cabling management system, improving the accuracy and efficiency of cabling management.

[0045] Correspondingly, such as Figure 6 As shown, the present invention also proposes a structured cabling management method, which is applied to a structured cabling management system as described above, the method comprising: Step S101: Deploy and establish communication connections for the integrated cabling management system, and perform initial configuration for the integrated cabling management system; Step S102: The status information of the fiber optic cabling is collected in real time through the sensing layer and uploaded to the access layer. The access layer preprocesses the status information and forwards the preprocessed status information to the management layer. Step S103: Based on the management layer's parsing of the preprocessed status information, determine the port status, determine whether there are any abnormal events based on preset rules, and generate alarm information and forward it to the application layer when there are abnormal events. Step S104: After receiving the alarm information at the application layer, perform maintenance operations based on the alarm information.

[0046] In some embodiments of this application, the integrated cabling management system is deployed and connected for communication, and the integrated cabling management system is initialized and configured, specifically as follows: Build the system hardware architecture and complete the deployment and communication connection of integrated intelligent fiber optic distribution subframes, distribution frame management units, servers, and management terminals; Import basic resource information through the management terminal. The basic resource information includes physical location information, equipment information, and link planning information. Establish resource mapping relationships, including mapping between ports and physical locations, mapping between ports and devices, and mapping between preset links and ports; Configure system parameters, including the detection cycle of the sensing module, alarm threshold, communication protocol, third-party interface parameters, and user permissions.

[0047] Specifically, the system hardware architecture is first built, completing the deployment and communication connection of integrated intelligent fiber optic distribution subracks, distribution frame management units, servers, and management terminals. Basic resource information is imported through the management terminal, including physical location information (computer room, cabinet, floor), equipment information (distribution frame model, number of ports, port type), and link planning information (preset link start point, end point, attenuation threshold). Resource mapping relationships are established, including mapping between ports and physical locations, mapping between ports and devices, and mapping between preset links and ports. System parameters are configured, including the detection cycle of the sensing module (configurable from 100ms to 1s), alarm thresholds (link attenuation threshold, temperature and humidity threshold), communication protocols, third-party interface parameters, and user permissions.

[0048] In some embodiments of this application, the step of collecting the status information of the optical fiber cabling in real time through the sensing layer, uploading the status information to the access layer, preprocessing the status information through the access layer, and forwarding the preprocessed status information to the management layer specifically involves: The port status sensing module of the integrated intelligent fiber optic distribution subframe collects port plug-in / plug-out status and link attenuation values ​​according to the configuration cycle. The embedded control module filters and encrypts the collected port plug-in / plug-out status and link attenuation values ​​to generate standardized data frames. Standardized data frames are uploaded to the patch panel management unit via the communication network. After the patch panel management unit aggregates and preprocesses the data from multiple sub-frames, it is uploaded to the integrated cabling management server. If communication is interrupted, the subrack caches the data locally, the management unit stores the aggregated data, and the transmission is automatically resumed after communication is restored.

[0049] In this embodiment, the port status sensing module of the integrated intelligent fiber optic distribution subrack first collects port plug-in / plug-out status and link attenuation values ​​according to the configuration cycle; the embedded control module filters and encrypts the collected raw data to generate standardized data frames; the data frames are uploaded to the distribution frame management unit through the communication network, and the management unit aggregates and preprocesses the data from multiple subracks before uploading it to the integrated cabling management server; if communication is interrupted, the subrack caches the data locally, the management unit stores the aggregated data, and the transmission is automatically resumed after communication is restored.

[0050] In some embodiments of this application, the management layer parses the preprocessed state information to determine the port status, judges whether there are abnormal events based on preset rules, and generates alarm information and forwards it to the application layer when there are abnormal events. Specifically: Based on the structured cabling management server, the data frames are decrypted and parsed to update the port status, link status, and environment status in the resource database; Determine if the port status has changed; if so, record the change information. Based on preset rules, determine whether it is an illegal change; if so, mark it as an abnormal change and trigger an alarm. The server generates alarm information according to the configured alarm level based on the status judgment result.

[0051] Specifically, after receiving the data, the integrated cabling management server first decrypts and parses the data frame, and updates the port status, link status, and environment status in the resource database; it then determines whether the port status has changed (e.g., from connected to disconnected), and if so, records the change information (change time, change type, and current status); it then determines whether the change is illegal (e.g., a patch cord operation not associated with a work order) based on preset rules, and if so, it marks it as an abnormal change and triggers an alarm; based on the status judgment result, the server generates alarm information according to the configured alarm level (including alarm type, occurrence time, associated resources, and handling suggestions).

[0052] In some embodiments of this application, after the application layer receives the alarm information, maintenance operations are performed based on the alarm information, specifically as follows: Send alarm notifications to designated maintenance personnel via terminal devices; Maintenance personnel receive alarm information through the management terminal. After confirming the alarm, the system records the confirmation time. Maintenance personnel go to the site to handle the fault. After the fault is handled, they submit the handling result on the management terminal. The system updates the alarm status to "closed loop" and records the handling process.

[0053] Specifically, alarm notifications are sent to designated maintenance personnel via APP push notifications; maintenance personnel receive alarms through management terminals, and after confirming the alarm, the system records the confirmation time; maintenance personnel go to the site to handle the fault, and after handling it, they submit the handling result on the management terminal, the system updates the alarm status to "closed loop" and records the handling process.

[0054] Furthermore, when a patch cord operation is required, the administrator creates a maintenance work order on the management terminal, specifying the operation type (add / modify / delete link), target port, operator, and completion deadline. After the work order is approved, the server issues a patch cord guidance instruction to the corresponding patch panel management unit. The management unit then issues the instruction to the target patch panel, and the port indicator module on the patch panel illuminates the LED indicator (flashing) of the target port according to the instruction. The maintenance personnel complete the patch cord operation based on the graphical path prompts and indicator light guidance on the management terminal. The system monitors port status changes in real time, and upon confirming the completion of the operation, automatically updates the link information and ledger, closes the work order, and records the operation trajectory.

[0055] Furthermore, this solution will now be explained in conjunction with specific application scenarios.

[0056] First, we set the application scenario as a large data center application scenario.

[0057] 1. Deployment Environment A cloud computing data center has 10 server rooms, each with 20 server racks. Each server rack is equipped with four 48-port integrated intelligent fiber optic distribution subframes, for a total of 3,840 fiber optic ports. It needs to be integrated with the data center's existing DCIM system, NMS system, and work order system.

[0058] 2. System Configuration Sensing layer: Uses a 48-port integrated intelligent fiber optic distribution subframe, supports LC single-mode ports, and has built-in temperature and humidity sensors and vibration sensors; Access layer: Two patch panel management units are deployed in each computer room, with a primary and backup redundancy design.

Management level: Deploy one integrated cabling management server, with a database using a MySQL cluster + Redis cache, supporting data storage for tens of millions of ports; Communication network: The internal computer room uses gigabit Ethernet, the computer rooms are connected by 10-gigabit fiber optic links, and the management terminal and the server use wired communication. Application layer: Operation and maintenance personnel are equipped with PC terminals (with client software installed) and mobile terminals (with operation and maintenance APP installed), and management personnel conduct global monitoring through the Web operation and maintenance management platform.

[0059] 3. Implementation Process S1: System initialization. Import physical location information such as computer room, cabinet, and U-position through the DCIM system, and import basic resource information such as port, link, and device through Excel to establish the mapping relationship between port-device-physical location; S2: Deploy integrated intelligent fiber optic distribution subracks and management units to complete power and communication line connections, and remotely configure subrack parameters (sensing module detection thresholds, alarm rules, and communication cycles) via a server. S3: Perform patch cord binding by scanning the patch cord RFID tag and port tag with a mobile terminal APP to establish the association between the patch cord and the port, and enter information such as patch cord model and laying path; S4: The system is online and running, collecting port status, link attenuation, and environmental data in real time. The topology map and port status are displayed through the management terminal, and the data is synchronized to the DCIM system and NMS system. S5: Operation and maintenance example: When a new business link needs to be added, the administrator creates a jumper work order on the Web platform, specifies the start and end ports, the system automatically generates the jumper path and issues guidance instructions, the target port green light flashes, the operation and maintenance personnel complete the jumper operation according to the APP prompts and indicator light guidance, the system automatically records the changes and updates the ledger; S6: Fault Handling Example: When a port is in an abnormal state, the system automatically triggers an important level alarm and notifies the operation and maintenance personnel via the APP. At the same time, the faulty link is marked in red on the topology map. The operation and maintenance personnel can view the link attenuation trend and recent operation records through the APP, take the test equipment to the site for troubleshooting, and submit a closed loop in the APP after the problem is resolved. The system automatically updates the status and synchronizes it to the work order system.

[0060] 4. Implementation Results Port status detection response time ≤ 80ms, alarm accuracy ≥ 99.95%; The jumper operation error rate has been reduced from 15% to 0.08%, and the average fault repair time has been shortened from 4 hours to 25 minutes; The port resource utilization rate has increased from 60% to 82%, saving approximately 2 million yuan in annual investment for data center expansion.
