[0101] In actual operation, the safety monitoring system platform primarily provides the basic operating environment, including a main chassis, power supply, fans, switching, and storage. Key functions include the following: Power Conversion Unit: The monitoring host utilizes the onboard DC110V power supply. The platform's power board isolates and converts the incoming DC110V to DC24V, which is then transmitted to each subsystem and functional board via the backplane. Platform Backplane: Connectors for each board are installed on the backplane, providing power and Ethernet access for each subsystem board. Active Fan Cooling: The platform features a 1U fan tier for board cooling, and the fan power supply includes short-circuit and overcurrent protection. TSN Master Control Unit (CPU): This unit communicates with the train's TSN network, processes data internally, stores data, and manages fan speed.

[0107] In this embodiment, the CPU unit of the monitoring platform collects the train control system clock information from the control network through the TSN interface using the TRDP protocol at a specific period. When it is determined that the clock value is valid and has a large difference with the local clock, the CPU unit synchronizes the local clock according to the network system clock.

[0108] The CPU unit packages the local time and control network data and sends them to the storage unit and each subsystem in a specific period through the UDP broadcast protocol. After receiving the message, each unit determines that the clock value is valid and the local clock difference is large, and then synchronizes the local time according to the CPU unit clock.
