Description

Technical Field

[0001] This utility model relates to the field of ATP equipment testing technology for high-speed trains, specifically to a real-time monitoring device for ATP power supply and track circuit. Background Technology

[0002] During operation or startup, the ATP (Automatic Train Protection) system on high-speed trains may experience mid-journey stops or fail to start normally due to power supply or relay failures. When such failures occur, it is difficult for electrical and onboard maintenance personnel to quickly determine the cause, especially for power supply fluctuations, which are even more challenging to diagnose. To more quickly determine whether ATP operational abnormalities are caused by abnormal power supply fluctuations, real-time monitoring of the ATP equipment's power supply is necessary, with alarms triggered when abnormalities occur.

[0003] Track circuits are a crucial component of railway traffic safety. However, they suffer from drawbacks such as high inductance, high leakage conductivity, large traction current, and crosstalk interference. Due to the complexity of the transmission system, various external interferences are inevitably superimposed. These interferences can affect signaling equipment and even jeopardize traffic safety. Therefore, it is essential to provide a means for online real-time data acquisition and analysis.

[0004] High-speed trains have extremely stringent requirements for the stability of onboard equipment. The technical specifications for various equipment clearly define the specific parameter ranges required for their operation, including temperature, humidity, and smoke concentration. Abnormal temperature, humidity, and smoke concentration can adversely affect the normal operation and lifespan of the equipment. Therefore, it is necessary to monitor the operating environment of onboard equipment to promptly identify potential faults or safety hazards. Summary of the Invention

[0005] To address the problem that existing ATP (Automatic Train Protection) equipment for high-speed trains cannot perform comprehensive monitoring, this utility model proposes a real-time monitoring device for ATP power supply and track circuits. The onboard monitoring device consists of a TCR board, a PDD board, a CPU board, a POWER board, and a DCMS board. It collects ATP power supply voltage, induced current, original signals from the vehicle-to-ground induction signal coils, cabinet temperature and humidity, and smoke detection information in real time. After processing the collected data, it transmits it to the ground level through the DMS onboard host to achieve real-time monitoring.

[0006] To achieve the above objectives, this utility model proposes a real-time monitoring device for ATP power supply and track circuit, comprising an on-board layer and a ground layer. The ground layer includes a data analysis server and a monitoring terminal. The on-board layer includes a DMS on-board host, a vehicle power supply, and an ATP device.

The baseboard connector is communicatively connected to the CPU plug-in board.

[0016] The number of resistor divider circuits and isolated operational amplifier units is multiple.

[0017] The resistor divider circuit uses the voltage division principle of resistors to reduce the higher vehicle power supply voltage to a range acceptable to the AD module, ensuring that the AD module can safely and accurately acquire voltage signals. An isolation operational amplifier is used to isolate the signal, preventing interference signals and abnormal voltages from affecting subsequent circuits and amplifying the signal. Combined with the AD module, signal conversion is completed to achieve ATP power supply voltage acquisition.
