[0119] The second application layer is used to assemble various business modules based on business logic;

[0120] The second display layer is used for visual display to users and interaction with users.

[0121] Specifically, the main business of the vehicle-side integrated information platform is to receive maintenance tasks, execute maintenance tasks (detection-related systems for data collection and identification, maintenance-related systems for defects) and upload maintenance results, and it has the vehicle control functions of precise positioning, automatic and accurate positioning and stability maintenance. Its system architecture can adopt a multi-level system structure system based on the Java standard framework structure, including terminal equipment layer, second interface layer, second data layer, second technology layer, second application layer and second display layer.

[0122] The terminal equipment layer is responsible for data connection with the robot maintenance operation terminal, vehicle group supporting terminal and intelligent perception identification terminal, receiving and forwarding data, and realizing interconnection with external systems.

[0123] The second interface layer is used to connect to external systems according to various network protocols (http protocol, https protocol, etc.), receive requests and data sent by external systems, and return response results corresponding to the requests to external systems, thereby achieving interconnection with external systems.

[0124] The second data layer can include components such as databases, data warehouses, data integration, and data mining, which are used to store and manage data, aggregate and analyze large amounts of data, integrate data from different data sources, and discover hidden information and patterns through data analysis.

[0125] The second technical layer includes the data platform and the technical platform. The data platform is used to implement data mining, data fusion and data analysis based on microservices, and can also realize visualization. The data processed includes business data and IoT data. The technical platform is used to generate business modules, which can realize workflow engines, data distribution, distributed tasks, operation and maintenance automation, data transmission and log monitoring.

[0126] The second application layer mainly connects the business processes of receiving maintenance tasks, checking maintenance tasks, system self-checking, starting operations, intelligent detection, mid-point analysis, return maintenance, maintenance return, and maintenance completion to form a complete business logic, and performs distributed calling and assembly of various business modules according to the business logic.

[0127] The second display layer is displayed in the form of map visualization, which manages the entire life cycle of the train maintenance task, and visualizes the data of each stage from the train receiving the maintenance task to the end of maintenance.

[0130] Specifically, since the intelligent self-wheeled operation and maintenance system of the rail transit traction power supply contact network includes a ground remote computer room part and a self-wheeled operation and maintenance equipment vehicle group part, a cloud-edge-end collaborative network can be built. This network is a high-availability, high-bandwidth, and low-latency network system that integrates evaluation and maintenance and collaborates with the cloud-edge-end. It ensures cloud-edge data dump in two scenarios, namely, safe and high-speed transmission of monitoring data in the moving vehicle group and large-scale data in a stationary state, and ensures safe and high-speed transmission of various on-board systems and supporting terminals under the vehicle group local area network.

[0131] The cloud-edge-end collaborative network can be built based on the 5G (5th Generation Mobile Communication Technology) network. The operation and maintenance execution process uses 5G technology, and the vehicle-edge-end integrated information platform needs to upload positioning data and safety status monitoring data to the intelligent operation and maintenance cloud platform in real time; 5G millimeter wave technology is used in the garage scenario, and the vehicle-edge-end integrated information platform interacts with the intelligent operation and maintenance cloud platform through a high-speed wireless network, including receiving maintenance task data and uploading maintenance task results (image data, scene model data, and maintenance results, etc.).

[0132] In the vehicle-end integrated platform, a core switch is installed in the vehicle-mounted cabinet of the vehicle. The servers of each vehicle-mounted system are deployed and connected to the core switch. The supporting data acquisition terminals, algorithm all-in-one machines, embedded systems and other equipment of each system are uniformly allocated ports on the core switch. After access, data can be securely transmitted within each subsystem and between subsystems in the local area network. At the same time, a wireless router is set up to realize wireless access of data to the vehicle-mounted local area network to complete the transmission.

[0134] In order to meet the requirements of precise positioning, conventional power vehicles are equipped with a driver display screen, and main power vehicles need to modify the traction and braking systems and install a driver display screen (DMI for short) and a self-resetting button.

[0135] In order to meet the interaction between the crew and ground maintenance dispatchers, monitoring equipment is installed in the driver's cab of conventional power vehicles and main power vehicles to record the maintenance operations of the crew.
