Analysis and Elimination of Electrical Faults in Urban Rail Vehicles Based on TCMS Terminal Simulation Device
In the operation of urban rail transit vehicles,the electrical control system is the core and key system of urban rail transit vehicles,which is related to the operation and stopping of vehicles.Based on the urban rail vehicle elec-trical fault testing platform,this article presents the phenomenon of five types of faults occurring:cab occupancy relay,22-K151 relay,brake release relay,door closed relay,and BHB abnormal disconnection.The corresponding faults are analyzed and verified in terms of train electrical control system interface,logic analysis,and elimination.
