【Abstract】 This paper proposed the necessity of online monitor system for the running gear of electric vehicle from urban vehicle from urban railways,introduced the principle of the monitor system and part of key components,and offered an overall design plan. Based on the plan,the hardware of the monitor system was designed and configured,anti-interference design was made through analysis of interference,software algorithm of fault diagnosis was formulated,and practical cases on a trial operation were analyzed. The result showed that the control parameters were stable,devices could run stably,and the target was achieved,which lay the foundation of the automatic detection of the running gear of electric vehicles from urban railways.更多还原
