[0002] The monitoring of high-speed rail cables is crucial to the safe operation of high-speed rail. High-speed rail cables are an important part of power transmission and signal transmission. High-speed rail cables include the main core, the first ground loop current wire and the second ground loop current wire. Their health directly affects the safe operation of high-speed rail. If the cable is aged or fails, it may cause power supply interruption, which in turn affects the normal operation of the train and even causes safety accidents. Therefore, intelligent real-time monitoring of high-speed rail cables and timely detection and handling of potential problems are the key to ensuring the safe operation of high-speed rail.
