With its speed, high-speed rail has really shortened the space distance, changed and affected our life. During the train operation, a set of key technical equipment to ensure the safety of train operation and improve transportation efficiency is the train overspeed protection system, referred to as \"on-board ATP\".
On-board ATP is the core safety equipment of train operation control system, including on-board host, wireless transmission unit, transponder information receiving unit, track circuit information reader (TCR), speed measurement and ranging unit, man-machine interaction interface unit (DMI), train interface unit (TIU), judicial record unit (JRU) and other subsystems.
High-speed rail vehicle equipment has audio, vehicle video surveillance, vehicle display, vehicle positioning terminal, vehicle antenna, security equipment vehicle station, vehicle monitoring system
