Abstract:

Locomotive traction motor is the heart of important equipment,which ensures traffic safety and control of key equipment of locomotives.Real-time monitoring of locomotive traction motors can reduce the failure rate,improve safety and efficiency of railway transport and also lay a good foundation for achieving the status of maintenance equipment.This article presents the overall design plan of the locomotive traction motor fault diagnosis device.Through a lot of theory and practice of authentication,single-channel DC voltage isolation sensor is adopted to achieve the accurate data collection of 6-channel traction motor current,and fulfill fault diagnosis through Petri net theory.

Key words: traction motor;reliability;software and hardware design
