A multi-function, easily extensible and portable tracking and monitoring system is designed for traction and drive unit to meet the growing requirements of high-speed Electric Motor train Units（EMUs）, which is increasingly complex for real-time monitoring system. The design principle of the embedded hardware system based on the modular structure of cPCI bus is presented, and the realization of software functions such as on-line real-time data processing, offline data analysis, and human-machine interaction is put forward on the basis of LabVIEW development platform. Furthermore, the Visual Instrument（VI） design and scheduling mechanism based on state-machine are elaborated, and the measurement algorithm and its implementation of the traction motor＇s input power and constantly changing signal frequency of the monitoring system is also analyzed. The system is applied in certain models of the high-speed EMUs, and its stable operation, flexible settings, high accuracy and good application effect makes it provide a scientific guarantee for the safe operation of the high-speed EMUs.
