In this paper, much research is done on the traction and transmission monitoring system design and implementation of data acquisition, display, analysis and processing for the EMU’s traction and transmission system. On the basis of description of traction drive unit compositions and testing requirements, the hardware framework of traction and transmission monitoring system based on CPCI bus technology is presented in details. The testing system is then designed which is capable of electrical parameters data processing, display, storage, etc. by using LabVIEW software as the development platform. The system is miniature and provides a scientific technique method and assessment for the judge of parameter time histories characteristic analysis of the traction drive unit key components which makes it have a high application value.
