Abstract
In order to solve the problem of delay and safety of EMU, caused by insulation decrease, temperature jump, open circuit, and structural damages of bogie temperature sensor, this paper analyzes the causes of failure, expounding the defects of traditional structure and installation method of the sensor on the bogie. By discussing two kinds of temperature monitoring methods (infrared and wireless technologies), it is shown that wireless sensor technology is usable in temperature monitoring redundancy design. The proposal of installing the emergency wireless temperature monitoring device at the point of abnormal temperature is put forward, so as to ensure that the bogie temperature is always controlled and that the punctuality and safety of the EMU are improved.
