High-speed train running gear fault diagnosis and remote-monitoring system based on Internet of things

The invention relates to a high-speed train running gear fault diagnosis and remote monitoring system based on Internet of Things (IOT). The system provided by the invention comprises vehicle-mounted sensors, a signal conditioning and filtering device, a central processing system, a data input and output interface device, a vehicle depot information collection system, a nationwide train maintenance system and a man-machine interaction device. With the arrangement of a plurality of the vehicle-mounted sensors, accurate fault identification and positioning of key equipment of running gears are realized, prediction of faults is realized, train operational risks are reduced, remote diagnosis of faults is achieved, fault diagnosis cost is lowered, and fault diagnosis cycle is shortened.
