Abstract:

Based on the structure and characteristics of the existing railway safety monitoring system, this paper makes full use of the advantages of wireless sensor network(WSN) to improve the system. Zigbee and RFID technology are used to design the system architecture, network and data transmission scheme of WSNbased railway safety monitoring system. On the basis of the existing railway safety monitoring system, the function of the train-wayside transmission is added into the system so the environment condition in front of the train can be transmitted to the train. In addition, the deployment scheme of Zigbee node and RFID node is studied and a simulation case study of node deployment is used. This system can effectively reduce the difficulty of installation and deployment cost of railway safety monitoring system, and provide the running environment in front of the train in real-time, thus guarantee the safety of high-speed train operation.

Key words: intelligent transportation, railway safety monitoring system, wireless sensor network, system architecture, networking scheme, data transmission scheme, node deployment scheme
