Abstract: Aiming at the problems of unbalanced workload, ineffective utilization of operation relationship and great difference of operation quality in the detection station oftrouble of moving freight car detection system (TFDS), based on data transmission, data mining, intelligent discrimination and other technologies, the images and train information collected by multiple TFDS were uniformly stored and tasks were intelligently allocated to implement the functions of intelligent management, joint operation control and information transmission.Since the system was put into operation in Zhengzhou Group Co.Ltd., the operation effect is good, the fault detection efficiency is increased by more than 20%, which creates conditions for the deepening reform of vehicle system and provides technical support for professional management.
