英文摘要： The high-speed train health management is an important method to ensure the train safety with a high operational speed, it has become a key research in the field of maintenance and repair of the high-speed trains. Some preliminary results have already been applied. However, the existing technology is still facing some problems, such as incomprehensive state detection, disability of detecting tiny fault, low accuracy of fault location, and the low rate, small capacity, limited expansion capability of the detection network, etc. Therefore, the project aims at the key technology of the high-speed train health management, and the research content includes that the intelligent state monitoring and fault location method are studied, and the key technical scheme of the state monitoring data's effective extraction, ault diagnosis prediction and noise restrain are puts forward respectively; the high-speed train communication network(TCN) technology based on Ethernet and the topology structure and the communication protocol stack of the high-speed TCN based on Ethernet are studied as well, the communication scheduling method of the real-time virtual layer in the improved protocol is put forward, and the corresponding simulation calculation and tests are realized. This research can improve maintenance and repair of high-s
