Modeling and analysis of WSN-based emergency braking control for high-speed trains

摘要

This paper investigates the problem of wireless sensor network (WSN)-based emergency braking control for high-speed trains. The WSN deployed along railway line, is used to monitor the situation of the railway in real-time and transmit the sensor data to the high-speed trains several kilometers away. Based on the analysis of emergency braking scene and the analysis of communication and time-delay in WSN, a model of emergency braking control is established for the service of the deployment of WSN's nodes in the high-speed railway. A simulation experiment is given, and the strategy of the emergency braking control is obtained for the train speed of 350 km/h.
