Research on Intelligent Data Collecting Controller for Incipient Fault on Wheel-set of High-speed Train Based on Wireless Technology

Abstract

Wheel-set is the critical component of walking step of high-speed train and its running state is directly related to security of operation. The wheel-set is the moving parts of high-speed train, so it is very difficult for acquisition of incipient fault information. A intelligent data collecting controller is proposed for acquisition of online incipient fault information with the development of wireless communication technology such as Wi-Fi and 4G in this paper. With the controller, the Metal Magnetic Memory signal data of the wheel-set, the vibration sign data of walking step and the signal data of other sensors can be collected and processed. The test shows that the intelligent data collecting controller is stable and can meet the requirement of incipient fault information.
