英文摘要：
In order to improve the ability to judge the unusual situation and diagnose the failure of traction electromotor. This paper selects traction electromotor as the object for research, and a Fault Diagnosis Expert System based on TMS320LF2407A and expert system is designed. The theory of expert system and method of system design are presented, a new diagnosis method with expert data base, dedecing reasoning and knowledge acquisition is put forward. The knowledge database and the inference machine are completed, and a advanced method for traction electromotor diagnose is introduced which can satisfy the demand of locomotive＇s inspecting and diagnosing.
