[0046] During the product testing of the signal system, the stability and correctness of the product need to be verified. In particular, the coordination between data and systems requires an indoor simulation platform that simulates the vehicle equipment test environment. The indoor simulation platform can simulate and deduce the actual driver console simulation, load, engineering interface, line composition, slope and other conditions, thereby reducing the workload of actual on-site testing.

[0047] In view of the above situation, the present disclosure provides a simulation platform for simulating a vehicle-mounted device test environment. Figure 1 FIG. 1 is a schematic diagram of a simulation platform structure for simulating a vehicle-mounted device test environment according to an exemplary embodiment.

[0063] Communication protocol selection: Select the appropriate communication protocol (such as Modbus, TCP / IP and UDP, custom vernacular protocol, etc.) according to the IO module and system requirements. Protocol parameter configuration: Configure the module's network parameters (such as IP address, subnet mask, gateway, etc.) to support network communication. Set serial port parameters (such as baud rate, data bit, stop bit, check bit, etc.) to support serial port communication. Data

It can support multiple signal types, such as digital signals, analog signals, etc. It can have programmable functions, allowing users to customize output logic according to actual needs.

[0069] The reader module card is mainly used to read signals or data from external devices or systems. The reader module card is a multifunctional industrial automation control module provided by WAGO, mainly used to read digital signals.

[0074] Figure 4 FIG. 1 is a schematic diagram of the structure of a vehicle-mounted VOBC in a simulation platform according to an exemplary embodiment. Figure 4 As shown, the on-board VOBC includes ATP+ATO application layer 301, adaptation layer 302, IO input and output module 303, main control module 304, communication module 305 and dual-system synchronous voting module 306. Among them, ATP (automatic train protection subsystem) and ATO (automatic train driving subsystem) are two important components of the rail transit system. Their interaction and collaboration at the application layer are crucial to ensure the safety and efficiency of train operation. Among them, the main task of the ATP system is to ensure the safe operation of the train and prevent the occurrence of dangerous situations such as overspeeding and reckless advance of the train.

[0075] Among them, in the ATP+ATO system, the interaction between the ATP system and the ATO system at the application layer is mainly reflected in the following aspects:

[0076] Data sharing: The ATP system will transmit the train's speed, position, speed limit and other information to the ATO system in real time, which will serve as the basis for the ATO system to control the train operation. At the same time, the ATO system will also feed back the train's real-time operation data to the ATP system so that the ATP system can conduct safety supervision;

[0077] Collaborative control: The ATP system and the ATO system work together at the application layer to achieve safe operation and automatic driving of the train. For example, when the train stops at a station, the ATP system will send a signal to allow the door to open, while the ATO system is responsible for controlling the train to stop accurately at the predetermined parking position;

[0078] Fault handling: When a system fault occurs, the ATP system and the ATO system will collaborate according to the preset fault handling process to ensure the safe operation of the train.

[0079] The adaptation layer 302 is an intermediate layer that links the upper layer application and the secure computer platform, and plays a role in information exchange and API calling.

[0080] The IO input and output module 303 is mainly responsible for receiving and processing data or commands sent from the input device simulation console, and reporting the data or commands to the adaptation layer, which is then reported to the application by the adaptation layer.

[0081] The main control module 304 is a main control module, which is used to provide an operating environment for the application and control CPU detection, fault downtime processing, etc.

[0082] The communication module 305 is used to support the communication between the vehicle-mounted controller VOBC and the simulated driving console, and to support the communication between the vehicle-mounted controller VOBC and other modules, for example, to support the communication between the vehicle-mounted controller VOBC and the WAGO module.

[0083] Among them, in the two-by-two-take-two secure computer system, the dual-system synchronous voting module 306 usually includes two core processors, each of which is responsible for different tasks. One of the processors (such as core processor 1) is mainly responsible for running the task software and completing the specific commands that the system needs to execute; while the other processor (such as core processor 2) is mainly responsible for running the platform software and realizing the voting function. The two processors ensure a high degree of consistency in processing data and executing tasks through a synchronization mechanism, thereby improving the overall reliability and security of the system.
