According to the architecture of the subway, a traffic management system corresponding to the rail transit system can be constructed, but the traffic management system constructed according to the architecture of the subway will deploy more independent server groups, that is, the subsystems corresponding to each function in the traffic management system are deployed in an isolated and dispersed manner, thereby forming a complex chimney-type subsystem structure. For example, in the traffic management system, it includes server group A, server group B and server group C, wherein server group A is used to receive train operation information collected and sent by the train operation information collection device on the train, server group B is used to receive ticket sales and inspection information collected and sent by the automatic ticket vending and inspection equipment on the platform, and server group C is used to receive the train operation information sent by server group A and the ticket sales and inspection information sent by server group B, and manage the train based on the train operation information and ticket sales and inspection information. In the above system, multiple subsystems of a single functional system are all provided with independent server groups, and each subsystem corresponds to a server group, so that many identical or similar functions are used multiple times, resulting in low utilization of server resources, and because each server group is independent of each other, data is difficult to share between each server group, and the system as a whole will generate more redundant data, thereby making the operation efficiency of the entire traffic management system low.

[0036] With the gradual development of the domestic rail transit system, the field of transportation technology has higher demands on the structure and design of the traffic management system corresponding to the rail transit system.

[0037] Traditional traffic management systems are designed based on the architecture of subways, and the subsystems corresponding to various functions are deployed in an isolated and decentralized manner, thus forming a complex chimney-like system. Figure 1 , Figure 1 It is a structural diagram of a traditional traffic management system involved in this application, such as Figure 1 As shown, server group A is used to receive train operation information collected and sent by train operation information collection equipment on multiple trains (including train 1, train 2, ..., train x), server group B is used to receive ticket sales and inspection information of multiple passengers (including passenger 1, passenger 2, ..., passenger n) sent by automatic ticket vending and checking equipment, server group C is used to receive train operation information sent by server group A and ticket sales and inspection information sent by server group B, and manage trains based on the train operation information and ticket sales and inspection information. In the above system, multiple subsystems of a single functional system are equipped with independent server groups, and each subsystem corresponds to a server group, so that many identical or similar functions are used multiple times, resulting in low utilization of server resources, and because each server group is independent of each other, data is difficult to share between each server group, and the system as a whole will generate more redundant data, which makes the operation efficiency of the entire traffic management system low.

[0038] In response to the above-mentioned problems, the present application provides a traffic management system.

[0039] See also Figure 2 , Figure 2 This is a schematic diagram of the structure of a traffic management system provided by this application. Figure 2 As shown, the traffic management system includes: automatic ticket vending and checking equipment 100, train operation information collection equipment 200, network equipment 300 and cloud platform 400.

[0040] The automatic ticket vending and checking device 100 can be an image acquisition device, an infrared sensor, an automatic ticket vending system, an automatic ticket checking system, etc., and is used to obtain the ticket vending and checking information of passengers, including the train number, seat number, and boarding time of the train. Figure 2 In the traffic management system shown, the automatic ticket vending and checking device 100 obtains the passenger's ticket vending and checking information, and sends the passenger's ticket vending and checking information to the cloud platform 400 through the network device 300 .

[0041] The train operation information collection device 200 may be a global satellite positioning system, a speed sensor, an accelerometer, a gyroscope, and a parts fault diagnosis system, etc., which is used to obtain the train operation status, including the train's position, speed, acceleration, and speed change. Figure 2 In the traffic management system shown, the train operation information collection device 200 collects the train operation status from the train and sends the train operation status to the cloud platform 400 through the network device 300.

[0042] The network device 300 may be one or more of a router, a switch, a hub, a firewall, a gateway, a scheduler, a modem, and is used to enable connected devices to communicate with each other. Figure 2 In the traffic management system shown, the terminals (the train operation information collection device 200 and the automatic ticket vending and checking device 100 in the figure) can establish a connection with the cloud platform 400 and perform data exchange through network devices.

[0043] Cloud platform 400 includes an operation and maintenance management network, an external service network, and a business bearer network ( Figure 2 The business bearer network includes a train service domain and a passenger service domain, wherein the train service domain is used to obtain train operation information and dispatch trains, the train operation information includes the speed of the train and the train's route, and is used for information interaction between multiple electronic devices, and the multiple electronic devices include electronic devices on the train and electronic devices on the platform; the passenger service domain is used to provide passengers with ticket operation services, train information prompt services and broadcasting services.

[0044] In a possible embodiment, the train service domain includes a unified scheduling domain and an integrated application domain, and the business bearer network also includes a basic service domain, wherein the unified scheduling domain is used to obtain train operation information and schedule trains, and the train operation information includes the speed of the train and the train's route; the integrated application domain is used for information interaction between multiple electronic devices, and the multiple electronic devices include electronic devices on the train and electronic devices on the platform; the basic service domain is used to provide middleware services for the unified scheduling domain, the integrated application domain and the passenger service domain, and the middleware services include relational database services and time domain database services. The relational database services are used to support the addition, deletion, modification and search of relational data, and the time domain database services are used to collect and process data generated by multiple electronic devices.

[0045] In a possible embodiment, each service in the cloud platform 400 is a plurality of virtual instances, which may be virtual machines (VMs) or containers, wherein a virtual machine refers to a complete computer system with complete hardware system functions and running in a completely isolated environment, which is simulated by software, and the work that can be completed in a physical computer can be realized in a virtual machine. When creating a virtual machine in a computing device, part of the hard disk and memory capacity of the physical machine needs to be used as the hard disk and memory capacity of the virtual machine. Each virtual machine has an independent basic input / output system (BIOS), hard disk and operating system, and the virtual machine can be operated like a physical machine; a container is a portable software unit that can combine an application and all its dependencies into a software package, which is not limited by the underlying host operating system and does not need to build a complex environment, thus simplifying the process from application development to deployment.

[0046] exist Figure 2 In the traffic management system shown, the cloud platform 400 is the management node of the traffic management system, which is connected to the train operation information collection device 200 and the automatic ticket vending and checking device 100 through the network device 300, and receives the train operation information collected and sent by the train operation information collection device 200 and the passenger information collected and sent by the automatic ticket vending and checking device 100, and manages the train according to the train operation information and the passenger information.

[0047] It should be understood here that Figure 2 The traffic management system shown is only an example provided by the present application. In actual application scenarios, other information collection devices or electronic devices may also be included. For example, the above-mentioned traffic management system may also include a station broadcasting system. The station broadcasting system is connected to the cloud platform 400 through the network device 300. The cloud platform 400 can control the station broadcasting system to play information, and the cloud platform 400 can use a physical machine to replace its function.

[0048] It can be seen that in the traffic management system provided by this application, a total of four application domains are designed for various functions in the rail transit system, among which the service subject of the unified dispatching domain is the train, the service subject of the passenger service domain is the passenger, the service subject of the comprehensive application domain includes the train and the platform, and the service subject of the basic service domain is each system in the above-mentioned unified dispatching domain, passenger service domain, and comprehensive application domain. By dividing different application domains, each application domain can independently design its technical architecture and configure corresponding server resources, which can not only improve the utilization rate of server resources, but also by setting similar functions of multiple service subjects in the same application domain, data sharing between various functions is also easier to achieve, thereby making the collaboration and calling between various functions more convenient, and the operation efficiency of the entire traffic management system higher.

[0049] Combine the following Figure 3 For a detailed introduction to the relevant functions of the above cloud platform 400, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a cloud platform provided by this application, such as Figure 3 As shown, the cloud platform 400 includes an operation and maintenance management network, a business bearer network and an external service network, wherein the business bearer network includes a unified dispatching domain, a comprehensive application domain, a passenger service domain and a basic service domain.

[0050] In cloud platform 400:

[0051] (1) Operation and maintenance management network, which is used to manage and maintain the operation of the service bearer network. It includes cloud management module, network management module and security management module, among which:

[0052] 1) The cloud management module is used to manage and monitor the resources and services of the cloud platform 400. Its main responsibilities include resource allocation and scheduling, performance monitoring, automation management, security management, cost control, etc. The goal is to ensure the efficiency, reliability and security of the cloud platform 400 and provide high-quality cloud services.

[0053] 2) The network management module is used to manage and monitor the network where the cloud platform 400 is located. Its main responsibilities include configuring network equipment in the network where the cloud platform 400 is located, fault monitoring, troubleshooting, managing and optimizing the network, protecting and defending network security, and monitoring and optimizing network performance. The goal is to ensure the availability, reliability and security of the network and provide efficient network services.

[0054] It can be seen that the cloud management module mainly focuses on the management and monitoring of resources and services in the cloud platform 400, and the network management module mainly focuses on the management and monitoring of the network where the cloud platform 400 is located. Both are for the purpose of providing efficient, reliable and secure services for the cloud platform 400 for management and monitoring, but the scope and field of focus are different.

[0055] 3) The security management module is used to centrally manage and monitor the security affairs of the cloud platform 400. The functions of the security management center include but are not limited to: risk assessment, vulnerability management, security policy formulation, access control, identity authentication and authorization of the cloud platform 400.

[0056] In the cloud platform 400, the operation and maintenance management network plans to use a shared (public) cloud host resource pool. Here, the cloud host can also be called a virtual instance, including a virtual machine and a container.

[0057] A shared cloud host resource pool refers to cloud host resources that are shared in a computing environment. The counterpart of a shared cloud host resource pool is a dedicated cloud host resource pool, which refers to cloud host resources that are dedicated to a computing environment. For example, Figure 3 The train information acquisition system, automatic ticket vending and checking system, and electromechanical communication system in the system run on different virtual instance groups, that is, all three systems use dedicated cloud host resources.

[0058] Since a shared cloud host resource pool is shared by multiple systems or modules, using this resource pool can reduce the operating costs of a single system or module and provide flexible resource expansion and reduction functions for multiple systems or modules. The shared cloud host resource pool is suitable for small and medium-sized systems or modules or for users with low performance requirements.

[0059] Since a dedicated cloud host resource pool is a cloud host resource dedicated to a single system or module, the system or module in the dedicated cloud host resource pool will have higher and more stable performance than in a shared host resource pool, and the system or module in the dedicated cloud host resource pool is not subject to the security risks brought by shared resources. The dedicated cloud host resource pool is suitable for systems or modules with higher performance and security requirements.

[0060] For details about planning to use a shared cloud host resource pool and planning to use a dedicated cloud host resource pool in the subsequent introduction, please refer to the above description.

[0061] (2) External service network, used to provide an interface for external network access to cloud platform 400.

[0062] The external service network does not deploy resources in the cloud platform 400 provided in this embodiment. It is mainly used for data interaction between the cloud platform 400 and the external network. The specific functions include security protection of the external network, access to existing systems, access to user terminals, etc. Since the data involved in the external service network comes from a wide range of sources and some information involves personal privacy, security is a factor that needs to be considered when establishing the external service network. Ways to improve security include but are not limited to: identity authentication, access control, data encryption, etc.

[0063] (3) The service bearer network includes four application domains: unified dispatching domain, comprehensive application domain, passenger service domain, and basic service domain. Next, each domain in the service bearer network and each system in the domain are introduced in detail.

[0064] 1) Unified Scheduling Domain

[0065] This domain includes the train information acquisition system, monitoring system and line network dispatching system. Each of these three systems is planned to use a dedicated cloud host resource pool, and all use local data backup. Among them, data backup is the basis of disaster recovery. It refers to the process of copying all or part of the data set of the system or module to other storage media to prevent data loss due to operational errors or system or module failures in the system or module. Functional modules involved in emergency response and command and dispatch rescue in the unified dispatching domain (such as train information acquisition system and line network dispatching system) have application-level disaster recovery capabilities.

[0066] ① Train information acquisition system, used for train identification, tracking and display, operation diagram preparation, operation data recording, etc. The train information acquisition system and each train operation information collection device in the offline transportation system can be regarded as a two-level architecture consisting of a center + physical equipment, where the train information acquisition system is the line / line network center, including application servers, database servers, interface servers, gateway servers, central train dispatching workstations, timetable editing workstations and operation diagram display workstations; each train operation information collection device is a physical device within the management scope of the center, and the physical device is a station equipment, including ATS control workstations. The train information acquisition system is responsible for receiving and sorting out the train operation information collected by these physical devices.

[0067] ② Monitoring system, used for data collection and processing, general graphical interface, and monitoring of the operation of the train. Compared with the train information acquisition system, the data collected by real-time monitoring is more real-time. In some possible embodiments, the monitoring system also includes: power monitoring function to monitor the operating status of the train power equipment, such as switch position, fault status, voltage, current, etc. The monitoring system and each train operation information collection device in the offline transportation system can be regarded as a two-level architecture consisting of a center + physical equipment, in which the monitoring system is the center, and each device that needs to send corresponding monitoring information to the monitoring system is a physical device within the management scope of the center. The monitoring system is responsible for receiving and organizing the monitoring information of the train collected by these physical devices.

[0068] ③ The line network dispatching system is used to effectively manage and dispatch lines, vehicles and passengers. It involves optimizing line planning, vehicle dispatching, passenger management, emergency response and other aspects to ensure the efficient operation of the traffic management system. Among them, line planning refers to determining the best line planning plan by analyzing passenger needs, traffic and geographic information to meet the travel needs of passengers and minimize congestion and delays; vehicle dispatching refers to reasonably arranging the departure interval and running time of vehicles according to line planning and passengers to ensure that vehicles can arrive at the station on time and provide stable services; passenger management refers to reasonably arranging the capacity of vehicles and the service capacity of stations through passenger monitoring and prediction to avoid congestion and detention and provide a comfortable riding environment; emergency response refers to timely adjusting the operation plan of lines and vehicles in the event of emergencies or sudden situations to ensure the safety of passengers and smooth operation.

[0069] It can be seen that the above-mentioned line network scheduling system can be divided into three layers: data access layer, data processing layer and business application layer. The data access layer and data processing layer are used to interface with other systems in the unified scheduling domain to realize data transmission and processing. The business application layer is used to realize the line network scheduling business based on the received and processed data.

[0070] 2) Comprehensive application domain

[0071] This domain includes the electromechanical communication system, operation and maintenance system, and data integration system. The electromechanical communication system and the operation and maintenance system are planned to use a shared cloud host resource pool, while the data integration system is planned to use a dedicated cloud host resource pool. The electromechanical communication system, the operation and maintenance system, and the data integration system all use local data for backup.

[0072] ① Electromechanical communication system, including access control subsystem, telephone subsystem and video monitoring subsystem. The access control subsystem is used to confirm the information of passengers entering the platform and the train; the telephone subsystem is used to provide telephone communication services for train operation, train dispatching and command, and train disaster prevention alarm; the video monitoring subsystem is used to obtain images of the train and perform image processing and image analysis on the images of the train.

[0073] ② Operation and maintenance system, used to support and manage various infrastructures in rail transit systems (such as servers, network equipment, storage equipment, clock systems, power systems, axle counter monitoring systems, and microcomputer monitoring systems, etc.), usually used to ensure the normal operation of infrastructure and promptly handle corresponding faults and problems. It includes communication operation and maintenance system and signal operation and maintenance system. The communication operation and maintenance system is used to perform fault detection, statistical analysis, and risk assessment on the access control subsystem, telephone subsystem, video monitoring subsystem, automatic ticket vending and checking system, train information prompt system, and broadcasting system; the signal operation and maintenance system is used to perform fault detection on the above basic equipment.

[0074] The introduction of a professional operation and maintenance system can minimize infrastructure downtime, improve infrastructure availability, and ensure the normal operation of the traffic management system.

[0075] ③ Data integration system, used to integrate and manage data from various domains in the business bearer network. By integrating data from different data sources, data flow and sharing are realized. At the same time, by integrating data from different data sources, a more comprehensive and specific view is provided to help system decision-making or system problem repair. The data integration system consists of the data source layer, data integration layer, data storage layer, application support layer, and data application layer. Among them, the data source layer is the starting point of the data integration system. This layer establishes connections with various data sources (various domains in the business bearer network) to obtain original data. The data integration layer is used to integrate a large amount of original data obtained. The data storage layer is used to store the data integrated by the data integration system. The application support layer provides necessary support and services for the data application layer to ensure the normal operation and efficient performance of the data application layer. The data application layer is used for data application, including data analysis and display.

[0076] 3) The passenger service domain includes the automatic ticket vending and checking system, the train information prompting system, and the broadcasting system. The train information prompting system and the broadcasting system are planned to use a shared cloud host resource pool, while the automatic ticket vending and checking system is planned to use a dedicated cloud host resource pool. The automatic ticket vending and checking system and the train information prompting system use local data backup.

[0077] ① The automatic ticket vending and checking system is used to provide ticketing operation functions including ticket vending, ticket checking, ticket management and data statistics. The automatic ticket vending and checking system and the ticket vending and ticket checking equipment in the offline transportation system can be regarded as a two-level architecture consisting of a center + physical equipment, in which the automatic ticket vending and checking system is the center, the ticket vending and ticket checking equipment are physical equipment, and the automatic ticket vending and checking system is responsible for collecting and organizing the ticket vending information of the ticket vending equipment and the ticket checking information collected by the ticket checking equipment.

[0078] ② Train information prompt system, used to provide train service information to passengers' terminal devices. The system uses information broadcasting devices that can display video, such as station display terminals and on-board display terminals, as a medium and relies on multimedia network technology to provide comprehensive information services to the public traveling on rail transit. This includes providing passengers with real-time dynamic multimedia information such as boarding instructions, train arrival and departure times, train timetables, first and last train service times, operation notices, government announcements, and advertisements when rail transit operations are normal; in the event of an emergency, it provides passengers with emergency auxiliary information such as evacuation information and transfer guidance information. The train information prompt system and the information broadcasting devices that can display video in the offline transportation system can be regarded as a two-level architecture consisting of a center + physical equipment, in which the train information prompt system is the center and the various information broadcasting devices that can display video are physical devices within the management scope of the center.

[0079] ③ Broadcasting system, used to provide train service information to passengers through the platform broadcasting system. It mainly broadcasts relevant train operation information, announcements, train arrival and departure information, safety reminders, etc. through loudspeakers or audio equipment distributed around the station or platform. The broadcasting system and the sound signal broadcasting equipment in the offline transportation system can be regarded as a two-level architecture consisting of a center + physical equipment, in which the broadcasting system is the center and each sound signal broadcasting equipment is a physical equipment within the management scope of the center.

[0080] 4) The basic service domain includes system service modules, IoT service modules, and middleware service modules. Each module is planned to use a shared cloud host resource pool.

[0081] ① System service module, which is used to provide the cloud platform 400 with functions such as user registration, load balancing, link tracking, monitoring and alarm, and log service. Among them, the registration service is used to record the mapping relationship between various services in the unified dispatching domain, comprehensive application domain, and passenger service domain and the corresponding addresses of each service. A single service in each service calls other services in each service according to the mapping relationship. The log service is used to collect and store the logs of each service.

[0082] ② Internet of Things service module, which is used to provide the ability for each module in the business bearer network to connect and communicate with the external gateway, so as to realize the interconnection between each module and the external device. The external gateway is between the external device and the cloud platform 400, and is a bridge for information communication between the external device and the cloud platform 400.

[0083] ③Middleware service module, used to provide middleware services for various modules in the business bearer network, including distributed information, KV database, relational database, time series database, distributed object storage and other middleware services. Among them, the relational database service is used to support the addition, deletion, modification and search of relational data, and the time domain database service is used to collect and process the time series data generated by multiple electronic devices.

[0084] Middleware is an independent software layer that together with the operating system and database constitutes the three pillars of basic software. It is a basic software applied to distributed systems, located between applications and operating systems and databases, and provides a platform for the development, operation and integration of upper-layer application software. Middleware services solve common problems such as software interconnection and interoperability in heterogeneous network environments, and provide standard interfaces and protocols, etc., providing reusable "standard parts" for sharing resources between application software.

[0085] In traditional traffic management systems, applications are mostly deployed independently, and the required middleware is also deployed and maintained by the applications themselves. This not only causes a large number of duplications of middleware with the same functions, but also because the middleware and versions used by different application vendors and different routes are different, which further causes redundancy and waste of resources in the entire traffic system. In addition, the deployment mode of the traditional traffic management system is deployed in a closed intranet environment. Each system is independent of each other and there is no strong concept of application domain. In the cloud platform 400, the operation and maintenance management network, the business bearer network, and the external service network are first divided into three parts. In the business bearer network, the unified dispatching domain, passenger service domain, comprehensive application domain and basic service domain are divided according to the business type. By classifying highly related business functions into the same domain, not only the information security needs and business isolation needs are guaranteed, but also the needs of traffic management system integration are met.

[0086] It can be seen that the cloud platform 400 provided in the above embodiment fully adopts a technology stack including virtual machines, containers, etc. to realize various business functions of the traffic management system. Compared with the traditional traffic management system designed based on the subway architecture, the business function planning is more unified, the management interface is more unified, and the network resource utilization rate is higher. In addition, a basic service domain is designed in the business bearer network in the cloud platform 400, and the basic service domain provides middleware services. Compared with the traditional traffic management system, the introduction of middleware services in the basic service domain decouples the middleware and the application program, which not only reduces the redundancy caused by the duplication of middleware with the same function, but also reduces the development cost and operation and maintenance cost of the traffic management system, and further improves the availability of the system.

[0087] In the above-mentioned cloud platform 400, various functions in the rail transit system are divided into different application domains according to their service subjects and specific service contents. For each separate application domain, its technical architecture is independently designed and corresponding server resources are configured, so as to improve the utilization rate of server resources in the system. In addition, functions with similar service subjects and similar specific service contents are divided into the same application domain, which can also make data sharing between functions easier to achieve, so that the entire traffic management system can operate efficiently.

[0088] The above text has elaborated in detail the cloud platform in the traffic management system provided by the present application. Next, the transmission channel between the cloud platform in the system and the offline physical electronic device will be elaborated.

[0089] In the traditional traffic management system, there are a large number of different network transmission channels, including transmission channels from the control center to different stations, transmission channels between different stations and different trains, transmission channels between two stations, transmission channels between two trains, transmission channels from the control center to passengers, etc. Although such a design has good isolation, there will be a lot of duplicate construction, resulting in a waste of resources.

[0090] In the traffic management system provided in this application, the communication services of the entire system can be realized through three transmission channels, which can simplify network construction, reduce resource usage and reduce costs.

[0091] See also Figure 4 , Figure 4 This is a schematic diagram of the structure of a traffic management system provided by this application. Figure 4As shown, there are a first transmission channel, a second transmission channel, a third transmission channel and a fourth transmission channel between the cloud platform 400 and offline physical devices (such as trains, passenger terminal devices, ticket selling devices, ticket checking devices, etc.), wherein the first transmission channel is used for communication between the unified scheduling domain and the train, and to realize communication between the unified scheduling domain and the platform; the second transmission channel is used for communication between the passenger service domain and the passenger's terminal device; the third transmission channel is used for communication between different trains, and to realize communication between the train and the platform, wherein the communication information between different trains is forwarded through the cloud platform; the fourth transmission channel is a backup transmission channel, which is used to replace the failed transmission channel when the first transmission channel, the second transmission channel or the third transmission channel fails, so as to realize the function of the failed transmission channel.

[0092] It should be understood that in a specific implementation, the above four transmission channels may have specific names according to different communication services carried. Figure 4 Taking the cloud platform 400 shown in FIG. as an example, according to the four transmission channels in Figure 4 The communication services carried in the cloud platform 400 shown are as follows: the first transmission channel is called the unified dispatching A network, the fourth transmission channel is called the unified dispatching B network, the second transmission channel is called the passenger service network, and the third transmission channel is called the comprehensive bearer network.

[0093] Here, the unified dispatching network A is used to carry the communication services of the unified dispatching domain network A and the communication services of the vehicle-ground long-term evolution machine type communication (LTE-M) network A. The unified dispatching network B is a backup transmission channel for the unified dispatching network A. It is used to bear part or all of the communication services originally borne by the unified dispatching network A when the unified dispatching network A is congested or has problems. For a description of the unified dispatching domain, please refer to the above Figure 4 The relevant description in the article is not repeated here. The train-ground LTE-M network is an LTE-M communication technology. The train-ground LTE-M network is used to support communication between trains and IoT devices to meet the reliable communication needs between trains and IoT devices. LTE-M is a low-power wide area network technology designed specifically for the IoT. It provides higher coverage, lower power consumption and higher reliability, making the connection of IoT devices more convenient and efficient.

[0094] In a possible embodiment, the above-mentioned unified scheduling domain is divided into a unified scheduling domain A network and a unified scheduling domain B network, and the vehicle-ground LTE-M network is divided into a vehicle-ground LTE-M A network and a vehicle-ground LTE-M B network. At the same time, when there are communication services in the unified scheduling domain A network and the unified scheduling domain B network, the vehicle-ground LTE-M A network and the vehicle-ground LTE-M B network, the unified scheduling B network will carry the communication services of the unified scheduling domain B network and the communication services of the vehicle-ground LTE-MB network on the basis of serving as a backup transmission channel for the unified scheduling A network. Here, the unified scheduling domain is taken as an example to explain why the unified scheduling domain is divided into a unified scheduling domain A network and a unified scheduling domain B network.

[0095] The reason for dividing the unified dispatching domain into unified dispatching domain A network and unified dispatching domain B network is that each module in the unified dispatching domain is responsible for the dispatching of trains, which is the lifeblood of the entire traffic management system and is very important. Therefore, the communication services of the unified dispatching domain require two transmission channels, unified dispatching domain A network and unified dispatching domain B network, for transmission.

[0096] The communication services of the unified scheduling domain are transmitted through two transmission channels, namely, unified scheduling network A and unified scheduling network B, which has the following effects: ① The separation of network A and network B can increase the security of the network. For example, some enterprises will put important sensitive information in network A and public information in network B; ② The separation of network A and network B can optimize the allocation and use of resources. For example, in some systems, network A is responsible for the transmission of important services, and network B is responsible for the transmission of other services. By reasonably allocating the use of network A and network B, network resources can be used more efficiently; ③ The separation of network A and network B can better manage and control various services. For example, in some systems, team A is responsible for the operation and maintenance of network A, and team B is responsible for the operation and maintenance of network B. Each team is only responsible for handling the network it is responsible for, which can more effectively ensure the normal operation of the network.

[0097] Here, the passenger service network is used to carry the communication services of the passenger service domain, including the communication services of the automatic ticket vending and checking system, train information prompting system, and broadcasting system in the passenger service domain. The relevant contents of the passenger service domain can be found in the above Figure 4 The relevant description of the passenger service domain will not be described in detail here.

[0098] Here, the integrated bearer network is used to carry the communication services of the integrated application domain and the basic service domain, including the communication services of the electromechanical communication system, the operation and maintenance system, and the system service module. The relevant contents of the integrated application domain and the basic service domain can be found in the above Figure 4 The relevant descriptions of the comprehensive application domain and the basic service domain will not be described in detail here.

[0099] When using the above four channels, the cloud platform 400 needs to be adjusted, including setting up access / aggregation node devices on the service bearer network for access of terminal devices and systems, and setting up two Internet exits, namely, a business exit and an office exit, on the external service network.

[0100] It can be seen that the above Figure 4 The traffic management system shown realizes the communication service of the whole system through three transmission channels (ie, the first transmission channel, the second transmission channel and the third transmission channel mentioned above).

[0101] In addition, it can be seen that in the system provided by the present application, a backup transmission channel for the first transmission channel is also designed, which can take on the task of transmitting management messages between the cloud platform and the train originally undertaken by the first transmission channel when the first transmission channel is congested or has problems, so as to ensure the normal operation of the train management business.

[0102] In the above-mentioned embodiments, the description of each embodiment has its own emphasis. For the part that is not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.
