Portions and features of some embodiments may be included in or replace portions and features of other embodiments.

Herein, each embodiment may be referred to individually or collectively by the term "invention," which is merely for convenience and is not intended to automatically limit the scope of the application to any single invention or inventive concept if more than one invention is in fact disclosed. Herein, relational terms such as first and second, etc., are used solely to distinguish one entity or operation from another, and do not require or imply any actual relationship or order between these entities or operations. Furthermore, the terms "comprise," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, or apparatus comprising a set of elements includes not only those elements, but also other elements not explicitly listed. The various embodiments herein are described in a progressive manner, with each embodiment focusing on the differences from the other embodiments. Reference can be made to the common and similar parts between the various embodiments. For structures, products, etc. disclosed in the embodiments, the description is relatively simple because they correspond to the parts disclosed in the embodiments. For relevant parts, refer to the method description.

[0037] Currently, the intelligent linkage of rail transit lines generally involves rail transit equipment such as the integrated monitoring system (ISCS), environmental and equipment monitoring system (BAS), broadcasting system (PA), video surveillance system (CCTV), passenger information display system (PIS), platform door system (PSD), automatic ticket collection system (AFC), lighting, vertical elevators, escalators, and entrance and exit roller shutters. However, since most rail transit stations are built based on the station-level ISCS framework, lacking a comprehensive design within the framework of the line network capability platform, the following problems exist when implementing intelligent linkage of rail transit lines based on the station-level ISCS:

[0038] (1) Only supports the control of rail transit equipment on this line

[0039] The intelligent linkage implemented based on station-level ISCS only supports the intelligent linkage of stations on the line during the construction of new lines. It is difficult to achieve intelligent linkage of rail transit equipment across lines at transfer stations.

[0040] (2) The control authority of the station-level integrated monitoring system is chaotic

[0041] When intelligent linkage is implemented based on the station-level ISCS and is applied in single-line stations, the station integrated monitoring system needs to reclaim permissions from the line center-level integrated monitoring system. For multi-line stations, there will be conflicts in the authority management of the station integrated monitoring systems of different lines. For example, when implementing intelligent linkage at a certain station, it is necessary to reclaim permissions from the center-level integrated monitoring systems of other lines. At the same time, there are also conflicts in the authority control of the station-level ISCS of different lines over the cross-line rail transit equipment of the station. It can be seen from this that if intelligent linkage is based on the station-level ISCS, for transfer stations, there will be a large number of operations in which the station integrated monitoring system reclaims permissions from the cross-line center-level integrated monitoring system.

[0042] (3) Continuous investment risk when new lines are connected

[0043] With the rapid development of urban rail transit, the gradual increase in opened lines and operating mileage, transfer stations have gradually expanded from two-line transfers to three, four, and even more complex ones. According to incomplete statistics, stations with planned four-line transfers include: Guangzhou South Station in Guangzhou (Lines 2, 7, 22, Foshan Line 2), Shenzhen Chegongmiao Station (Lines 1, 7, 9, 11), Nanjing South Station in Nanjing (Lines 1, 3, S1, S3), Shanghai Longyang Road Station (Lines 2, 7, 16, 18), and Caoyang Road Station (Lines 3, 4, 11, and 14). Meanwhile, Guangzhou Railway Station, in addition to the already opened Lines 2 and 5, will also feature the under-construction northern extensions of Lines 11, 14, and 22, the future Line 37, Foshan Line 5, and the Guangzhou-Qingyuan Intercity Railway. In the future, the number of stations with planned four-line transfers will reach eight.

[0044] Due to the uncertainty surrounding the connection of existing subway stations to subsequent transfer lines, intelligent linkage implemented using station-level ISCS generally only controls rail transit equipment at stations on the same line, failing to adaptively connect and control rail transit equipment on newly added lines. This situation necessitates adapting the existing station-level ISCS to accommodate each new line, requiring additional investment for each new line addition.

[0045] (4) Poor scalability

[0046] Intelligent linkage applications built on a station-level ISCS can only utilize the capabilities of that station-level ISCS. However, as a business production system, the station-level ISCS lacks the ability to continuously iterate and scale in cloud computing and network-based operations. Furthermore, most intelligent linkage applications based on the station-level ISCS utilize a single-station physical machine resource deployment model, resulting in limited computing power and inability to support the implementation of complex business logic.

[0047] (5) Comprehensive analysis of cross-station business is not supported

[0048] Intelligent linkage applications based on station-level ISCS construction are generally deployed independently according to the scenario linkage applications of each station. This makes the scenario linkage business of each station relatively fragmented, making it difficult to achieve efficient data analysis at the upper layer, unable to promote the continuous evolution of intelligent linkage applications, and unable to prioritize support for the construction of enterprise-level intelligent linkage applications and business specifications.

[0049] In order to solve the technical problem of low efficiency of multi-line network linkage control in rail transit in the prior art, an embodiment of the present invention provides a rail transit line network linkage control system. Figure 1 As shown, Figure 1 A schematic diagram of the structure of a rail transit network linkage control system provided in an embodiment of the present invention. The rail transit network linkage control system provided in an embodiment of the present invention includes an access layer, a platform layer, and an application layer. The platform layer includes multiple device control microservices corresponding to different device control systems. The device control microservices include at least one of a device monitoring function and a device linkage control function.

[0050] In this embodiment, the rail transit network linkage control system includes an access layer, a platform layer and an application layer. The platform layer includes a plurality of device control microservices corresponding to different device control systems. Among them, microservices refer to dividing a single application into many loosely coupled and independently deployable services. Each service runs in its own independent process, and services communicate with each other using a lightweight communication mechanism. Each service is built around a specific business and can be independently deployed in a production environment. In this embodiment, different device control microservices correspond to different device control systems. Each device control microservice includes at least one of a device monitoring function and a device linkage control function. The device monitoring function refers to the function of monitoring rail transit equipment, and the device linkage control function refers to the function of linkage control of rail transit equipment at different stations on different rail transit lines.

[0051] The access layer is used to access the equipment control system of the rail transit line, collect equipment data of the rail transit equipment from the equipment control system, and transmit the equipment data to the platform layer; and is used to receive equipment control instructions sent by the platform layer and send the equipment control instructions to the corresponding equipment control system so that the equipment control system can control the rail transit equipment of the corresponding rail transit line.

[0052] In this embodiment, the access layer is used to access the equipment control system of a rail transit line, which is used to control rail transit equipment at different stations on different rail transit lines. The access layer collects equipment data from the equipment control system, including the current status data and attribute data of the rail transit equipment. After collecting the equipment data, the access layer uses protocol parsing, middleware, and other technologies to be compatible with various communication protocols and software communication interfaces, achieving data format conversion and unification. The access layer then transmits the equipment data from the equipment control system to the platform layer, enabling data access.

[0053] In addition, in this embodiment, the access layer is also used to receive device control instructions sent by the platform layer. The device control instructions are used to control rail transit equipment on one or more rail transit lines. After receiving the device control instructions, the access layer sends the device control instructions to the corresponding device control system, so that the corresponding device control system can control the rail transit equipment on the corresponding rail transit line after receiving the device control instructions.

[0054] The platform layer is used to send device data to the corresponding device control microservice, so that when the device monitoring function of the device control microservice is called by the application layer, the device control microservice monitors the rail transit equipment according to the device data and sends the monitoring results to the application layer; and when the device linkage control function of the device control microservice is called by the application layer, the device control instructions of the device control microservice are sent to the access layer.

[0055] In this embodiment, the platform layer is used to receive the device data sent by the access layer, and send the device data of different device control systems to the corresponding device control microservices. Therefore, when the device monitoring function of the device control microservice is called by the application layer, the device control microservice can realize the function of monitoring the rail transit equipment according to the received device data, and can send the monitoring results to the application layer for display. In addition, when the device linkage control function of the device control microservice in the platform layer is called by the application layer, the device control microservice can determine the rail transit lines to be controlled, the stations to be controlled in the rail transit lines, and the rail transit equipment to be controlled in the stations according to the instructions of the platform layer, generate device control instructions, and send the device control instructions to the access layer. The access layer then sends the device control instructions to the corresponding device control system, so that the device control system controls the rail transit equipment to be controlled on multiple rail transit lines, thereby realizing linkage control of multiple rail transit lines.

[0056] The application layer is used to call the device monitoring function of the device control microservice in response to the first instruction to monitor the rail transit equipment; and to call the device linkage control function of the device control microservice in response to the second instruction to perform linkage control on the rail transit equipment of different rail transit lines.

[0057] In this embodiment, the application layer can provide native smart applications according to the intelligent linkage requirements of rail transit equipment, wherein the smart application is SaaS (Software-as-a-Service) to support intelligent linkage applications. Users can call the device monitoring function or the device linkage control function of the device control microservice through the intelligent linkage application. For example, in one embodiment, the user can set up the intelligent linkage application to view the monitoring data of all platform doors on all rail transit lines, and after confirmation, the first instruction can be sent to the intelligent linkage application. After receiving the first instruction, the intelligent linkage application can call the device monitoring function of the device control microservice corresponding to the platform door according to the first instruction, so that the corresponding device control microservice can monitor the platform door according to the device data of the platform door and generate monitoring data. After that, the intelligent linkage application receives the monitoring data sent by the corresponding device control microservice and displays it visually, thereby realizing the function of real-time monitoring of the platform door. In another embodiment, when the user needs to intelligently link rail transit equipment on multiple rail transit lines, the user can set the rail transit line that needs to be intelligently linked as Station A shared by Line 1, Line 2 and Line 5 in the intelligent linkage application, and then send a second instruction to the intelligent linkage application. After receiving the second instruction, the intelligent linkage application can call the device linkage control function of the device control microservice, and then send device control instructions to the device control system through the device control microservice, so that the device control system can link and control the rail transit equipment at Station A on Line 1, the rail transit equipment at Station A on Line 2, and the rail transit equipment at Station A on Line 5, thereby realizing the intelligent linkage function.

[0058] In addition, it needs to be further explained that for existing rail transit lines, by adaptively transforming and connecting the equipment control systems of existing rail transit lines, they can be integrated into the overall framework of the rail transit network linkage control system to meet the control requirements of the rail transit network linkage control system for existing rail transit lines.

[0059] As described above, an embodiment of the present invention provides a rail transit line network linkage control system, including an access layer, a platform layer, and an application layer. The platform layer includes multiple device control microservices corresponding to different device control systems. When a user needs to perform linkage control on multiple rail transit devices, a second instruction can be sent to the application layer. After receiving the second instruction, the application layer can call the device linkage control function of the device control microservice. The device control microservice sends the device control instruction to the device control system of the access layer, thereby performing linkage control on the rail transit equipment of different rail transit lines. The embodiment of the present invention uses the access layer to access the device control system of the rail transit line. The user only needs to send control instructions in the application layer to control the device control system through the device control microservice, thereby realizing linkage control of the rail transit equipment of multiple rail transit lines, improving the efficiency of multi-line network linkage control of rail transit, and solving the technical problem of low efficiency in multi-line network linkage control of the existing technology.

[0060] Based on the above embodiments, the equipment control system includes a line network integrated monitoring system and a line network passenger information system. The line network integrated monitoring system is used to monitor and control the rail transit equipment at different stations in different rail transit lines, and the line network passenger information system is used to control the passenger information release equipment at different stations in different rail transit lines.

[0061] In one embodiment, Figure 2 As shown, the equipment control system includes a line network integrated control system and a line network passenger information system. Among them, the line network integrated monitoring system is used to monitor and control the rail transit equipment in different stations in different rail transit lines. Specifically, in this embodiment, the line network integrated monitoring system communicates with the integrated monitoring system of each rail transit line through protocols such as Modbus. The line network integrated monitoring system can realize real-time monitoring and control of the rail transit equipment of each station of each rail transit line by calling the functional interface in the integrated monitoring system of each rail transit line. In one embodiment, the various functional interfaces of each station in the integrated monitoring system of each rail transit line are shown in Table 1.

[0065] In addition, the network passenger information system is used to control the passenger information display devices at different stations on different rail transit lines. For example, the network passenger information system can control the content displayed on the LCD devices of the network passenger information system at each station and the content played on the radio.

[0066] Based on the above embodiment, the device control microservice includes a comprehensive monitoring and control microservice and an information device control microservice; the comprehensive monitoring and control microservice includes a device monitoring function and a device linkage control function, and the information device control microservice includes a device linkage control function.

[0067] In one embodiment, Figure 2 As shown, the device control microservice includes the integrated monitoring and control microservice and the information device control microservice. The integrated monitoring and control microservice corresponds to the line network integrated monitoring system, while the information device control microservice corresponds to the line network passenger information system. Furthermore, the integrated monitoring and control microservice includes both device monitoring and device linkage control functions, while the information device control microservice includes device linkage control functions.

[0068] The integrated monitoring and control microservice is used to monitor rail transit equipment based on equipment data and send the monitoring results to the application layer when the equipment monitoring function is called by the application layer; and is used to generate a first equipment control instruction when the equipment linkage control function is called by the application layer, so that the platform layer sends the first equipment control instruction to the line network integrated monitoring system.

[0069] In this embodiment, when the equipment monitoring function of the integrated monitoring and control microservice is called by the application layer, the integrated monitoring and control microservice monitors the rail transit equipment at different stations on different rail transit lines based on the equipment data of different stations on different rail transit lines uploaded by the line network integrated monitoring system, generates monitoring data and sends the monitoring results to the application layer for display, so that users can view the monitoring data of rail transit equipment at different stations on different rail transit lines in the application layer.

[0070] In addition, the integrated monitoring and control microservice can control rail transit equipment at different stations on different rail transit lines. Specifically, the integrated monitoring and control microservice provides communication link status monitoring of rail transit equipment systems (PSD, BAS, AFC, PA, PIS, lighting, and security, etc.) at all stations on all rail transit lines, remote opening and closing control of single-side platform doors, mode control (operation mode, shutdown mode) of station lighting systems, mode dispatching function of environmental and equipment monitoring systems, mode control (normal service, shutdown service) of automatic ticket vending systems by equipment type, device-by-device control of escalators (upward start, stop, downward start), device-by-device control of vertical ladders (remote unlocking, remote locking), device-by-device control of rolling shutter doors (up, stop, down), and status monitoring of security equipment. When the device linkage control function of the integrated monitoring and control microservice is called by the application layer, the integrated monitoring and control microservice can determine the target station that needs to be linked controlled and the target rail transit equipment in the target station in all stations of all rail transit lines according to the device linkage control instruction sent by the application layer, and then generate a first device control instruction. The platform layer then sends the first device control instruction to the line network integrated monitoring system in the access layer, so that the line network integrated monitoring system can control the target rail transit equipment in the target station according to the first device control instruction.

[0071] The information device control microservice is used to generate a second device control instruction when the device linkage control function is called by the application layer, so that the platform layer sends the second device control instruction to the line network passenger information system.

[0072] In addition, in this embodiment, the information device control microservice corresponds to the line network passenger information system. When the device linkage control function of the information device control microservice is called by the application layer, the information device control microservice can determine the target stations that need to be linked controlled and the passenger information release equipment in the target stations in all stations of all rail transit lines according to the device linkage control instructions sent by the application layer, and then generate a second device control instruction. The platform layer then sends the second device control instruction to the line network passenger information system in the access layer, so that the line network passenger information system can control the passenger information release equipment in the target station according to the second device control instruction.

[0073] Based on the above embodiment, the information device control microservice includes a broadcast device control microservice and an LCD device control microservice.

[0074] The broadcast equipment control microservice is used to generate broadcast equipment control instructions when the device linkage control function is called by the application layer, so that the platform layer can send the broadcast equipment control instructions to the line network passenger information system. The broadcast equipment control instructions are used to manage the broadcast lists of broadcast equipment in different stations on different rail transit lines and control the broadcast content.

[0075] In one embodiment, Figure 3 As shown, the information equipment control microservice includes a broadcast equipment control microservice. Among them, the broadcast equipment control microservice is used to manage the broadcast list of the broadcast system of different stations on different rail transit lines, and to control functions such as broadcast release. When the device linkage control function of the broadcast equipment control microservice is called by the application layer, the broadcast equipment control microservice generates a broadcast equipment control instruction and sends the broadcast equipment control instruction to the line network passenger information system in the access layer, so that the line network passenger information system in the access layer can control the broadcast equipment of the PA system in different stations on different rail transit lines, such as uniformly controlling the broadcast equipment of stations shared by different rail transit lines to play station closing information, etc.

[0076] The LCD device control microservice is used to generate LCD device control instructions when the device linkage control function is called by the application layer, so that the platform layer sends the LCD device control instructions to the line network passenger information system. The LCD device control instructions are used to control the content displayed on the LCD devices in different stations on different rail transit lines. The second device control instructions include broadcast device control instructions and LCD device control instructions.

[0077] In this embodiment, the information device control microservice also includes an LCD device control microservice, which is used to control the content displayed on LCD devices at different stations on different rail transit lines. When the device linkage control function of the LCD device control microservice is called by the application layer, the LCD device control microservice generates LCD device control instructions and sends the LCD device control instructions to the line network passenger information system in the access layer, thereby enabling the line network passenger information system in the access layer to control the LCD devices of the PIS system at different stations on different rail transit lines, for example, to uniformly control the LCD devices of stations shared by different rail transit lines to display station closing information.

[0078] Based on the above embodiments, the platform layer is used to call the device monitoring function and device linkage control function of the comprehensive monitoring and control microservice and the device linkage control function of the broadcast device control microservice through the WebSocket protocol, and to call the device linkage control function of the LCD device control microservice through the restful protocol.

[0079] It should be noted that in this embodiment, the platform-level intelligent linkage application invokes the device monitoring and device linkage control functions of the integrated monitoring and control microservice via the WebSocket protocol, enabling device control of specialized subsystems across each line and station. Furthermore, the platform-level intelligent linkage application invokes the device linkage control functions of the broadcast device control microservice via the WebSocket protocol. Furthermore, the LCD device control microservice invokes its device linkage control functions via the RESTful protocol.

[0080] Based on the above embodiment, the platform layer also includes a data transfer module.

[0081] The data transfer module is used to send device data to the device control microservice, and to send the first device control instruction to the line network integrated monitoring system and the second device control instruction to the line network passenger information system.

[0082] In one embodiment, the platform layer further includes a data transfer module, which is used to send device data to the device control microservice, and to send the first device control instruction to the line network integrated monitoring system and the second device control instruction to the line network passenger information system. Figure 3 As shown in the figure, the data transfer module is the ICE Gateway. In the southbound direction, the ICE Gateway is responsible for connecting with the access layer's integrated monitoring system and passenger information system, enabling real-time point-to-point monitoring and control of various rail transit equipment. In the northbound direction, the ICE Gateway is responsible for connecting with the platform layer's broadcast equipment control microservice, LCD device control microservice, and integrated monitoring and control microservice, providing business support for the application layer.

[0083] On the basis of the above embodiment, the device control system further includes a wired network video monitoring system, and the platform layer further includes a video monitoring microservice, which includes a video monitoring function.

[0084] The access layer is also used to send the surveillance video data of the wired network video surveillance system to the video surveillance microservices of the platform layer.

[0085] The application layer is further configured to call the video surveillance function of the video surveillance microservice in response to the third instruction to view the surveillance video data.

[0086] The video surveillance microservice is used to send surveillance video data to the application layer when the video surveillance function is called by the application layer.

[0087] In one embodiment, Figure 3As shown, the access layer is also used to access the line network video surveillance system. This system includes video surveillance functions, which are used to capture surveillance images captured by cameras at different stations on different rail transit lines and generate surveillance video data, thereby enabling monitoring of different rail transit lines. In addition, the platform layer also includes video surveillance microservices, which include video surveillance functions.

[0088] Specifically, in this embodiment, after the access layer accesses the line network video surveillance system, it obtains the surveillance video data from the line network video surveillance system and transmits the surveillance video data to the video surveillance microservice of the platform layer. When the user needs to view the surveillance video data, the third instruction can be sent to the application layer. After receiving the third instruction, the application layer calls the video surveillance function of the video surveillance microservice, so that the video surveillance microservice transmits the surveillance video data to the application layer for visual display. It can be understood that in this embodiment, the user can specify the target station to be viewed in the third instruction, so that the video surveillance microservice only transmits the surveillance video data of the target station to the application layer. It should be further explained that in the embodiment of the present invention, the intelligent linkage application of the platform layer calls the video surveillance function of the video surveillance microservice through the restful protocol to realize the review of the video surveillance data of the station. The video surveillance microservice obtains the video surveillance data of each station from the line network video surveillance system of the access layer through the restful protocol.

[0089] Based on the above embodiment, the platform layer also includes video intelligent analysis services.

[0090] The access layer is also used to send surveillance video data from the wired network video surveillance system to the video intelligent analysis service at the platform layer;

[0091] The video intelligent analysis service is also used to perform intelligent analysis on surveillance video data and send the intelligent analysis results to the application layer.

[0092] In one embodiment, the platform layer also includes a video intelligent analysis service, which is used to perform intelligent analysis on the monitoring video data, such as human body detection in the target area, or detection of debris in the escalator area, etc. It is understandable that the intelligent analysis algorithm used by the video intelligent analysis service for the monitoring video data can be the intelligent analysis algorithm in the prior art. For example, the one-stage and two-stage algorithms in the prior art can be used for foreign object recognition, and the HOG3D algorithm in the prior art can be used for human body recognition, etc., which will not be repeated in this embodiment. It should be further explained that the intelligent linkage application of the platform layer in the embodiment of the present invention calls the video surveillance function of the video surveillance microservice through the restful protocol to obtain the video surveillance data of each station and complete the video analysis. The video intelligent analysis service obtains the video surveillance data of each station from the line network video surveillance system of the access layer through the GB28181 protocol.

[0093] Based on the above embodiments, Figure 4 As shown, it also includes an edge layer, which is used to access the station video surveillance system of each station;

[0094] The application layer is further configured to obtain station monitoring video data from the station monitoring video system of the edge layer in response to the fourth instruction.

[0095] In this embodiment, the rail transit line network linkage control system also includes an edge layer, which is used to access the station video surveillance system of each station, so that the application layer has the ability to obtain the nearest stream to the station surveillance video system of each station, so as to meet the requirements of the intelligent linkage scenario for the real-time performance and network bandwidth of the surveillance video data. Specifically, in this embodiment, when a user needs to directly obtain the surveillance video data of a certain station, the user can set the target station for viewing the surveillance video data in the application layer. After the setting is completed, the fourth instruction can be sent to the application layer. After receiving the fourth instruction, the application layer can obtain the station surveillance video data from the station surveillance video system of the target station in the edge layer, and visualize the station surveillance video data, so that the user can view the surveillance video data of the target station. Among them, the application layer can obtain the station surveillance video data from the station surveillance video system in the edge layer through the RTSP protocol.

[0096] Based on the above embodiment, the application layer includes single-line station linkage application and multi-line station linkage application.

[0097] The single-line station linkage application is used to respond to the single-line equipment linkage control instruction and call the equipment linkage control function of the microservice to perform linkage control on the rail transit equipment of a target rail transit line;

[0098] The multi-line station linkage application is used to respond to the multi-line equipment linkage control instructions and call the equipment linkage control function of the microservice to perform linkage control on the rail transit equipment of multiple target rail transit lines.

[0099] In one embodiment, Figure 4 As shown, the intelligent linkage application of the application layer includes a single-line station linkage application and a multi-line station linkage application. Among them, the single-line station linkage application is used to realize the linkage control of rail transit equipment at multiple stations on a single rail transit line, while the multi-line station linkage application is used to realize the linkage control of rail transit equipment at multiple stations on multiple rail transit lines. Specifically, in this embodiment, the second instruction includes a single-line equipment linkage control instruction and a multi-line equipment linkage control instruction. When the user needs to perform linkage control on the rail transit equipment on a rail transit line, the target rail transit line can be determined in the single-line station linkage application, and then the single-line equipment linkage control instruction is sent to the single-line station linkage application. After receiving the single-line equipment linkage control instruction, the single-line station linkage application can call the device linkage control function of the comprehensive monitoring and control microservice and the device linkage control function of the information equipment control microservice according to the target rail transit line set by the user, thereby controlling the rail transit equipment of each station on the target rail transit line. Similarly, when a user needs to perform coordinated control of rail transit equipment at various stations on multiple rail transit lines, they can set up multiple target rail transit lines in the Multi-Line Station Coordination Application and then send a multi-line equipment coordination control instruction to the Multi-Line Station Coordination Application. After receiving the multi-line equipment coordination control instruction, the Multi-Line Station Coordination Application can call the equipment coordination control function of the integrated monitoring and control microservice and the equipment coordination control function of the information equipment control microservice based on the multiple target rail transit lines set by the user, thereby controlling the rail transit equipment at various stations on the multiple target rail transit lines.

[0100] As described above, an embodiment of the present invention provides a rail transit line network linkage control system, including an access layer, a platform layer, and an application layer. The platform layer includes multiple device control microservices corresponding to different device control systems. When a user needs to perform linkage control on multiple rail transit devices, a second instruction can be sent to the application layer. After receiving the second instruction, the application layer can call the device linkage control function of the device control microservice. The device control microservice sends the device control instruction to the device control system of the access layer, thereby performing linkage control on the rail transit equipment of different rail transit lines. The embodiment of the present invention uses the access layer to access the device control system of the rail transit line. The user only needs to send control instructions in the application layer to control the device control system through the device control microservice, thereby realizing linkage control of the rail transit equipment of multiple rail transit lines, improving the efficiency of multi-line network linkage control, and solving the technical problem of low efficiency in multi-line network linkage control in the existing technology. Secondly, the embodiment of the present invention provides a standardized functional interface in the access layer to achieve remote control and scheduling of rail transit equipment on multiple rail transit lines, thereby avoiding conflicts when the station integrated monitoring system in each rail transit line reclaims authority from the central-level integrated monitoring system of non-line. Through unified scheduling and control at the line network level, the standardization of intelligent linkage services at the line network level is achieved. In addition, the embodiment of the present invention achieves overall decoupling of the access layer, platform layer, and application layer through the hierarchical construction of the rail transit line network linkage control system. While improving the expansion capability and scope of application of the rail transit line network linkage control system, it can avoid the binding of services and technology blockades by a single manufacturer.
