Abstract Abstract：Research purposes： In view of the problems existing in the current high-speed railway bridge health monitoring system in China, such as the difficulty of data acquisition, the low degree of automation of data acquisition and the low accuracy of data acquisition, a wireless bridge health monitoring system for high-speed railway based on ZigBee technology is designed by using the advantages of wireless sensor network, by changing the means and methods of data acquisition, the purpose of effectively improving the health monitoring level of high-speed railway bridges is achieved. Research conclusions： (1) The wireless sensor network has the characteristics of target tracking for dynamic optimization of network nodes. When designing high-speed railway wireless bridge monitoring system, the locating of data acquisition nodes is flexible and convenient, and the network is reliable. (2) Using the communication function of the wireless network module, it can realize the efficient online real-time data acquisition and transmission.(3) Through the simulation experiment of wireless bridge health monitoring system network model, it is proved that the system is accurate, timely, reliable and efficient. (4) The system can be widely used in the actual monitoring of the health condition of high speed railway bridges.
