Conventional long-span bridge structural health monitoring methods mainly use LoRa spread spectrum communication coverage method to access the monitoring sensor center;which is easy to be affected by a long monitoring period,resulting in abnormal monitoring of the vertical shape variables of the main beam.Therefore,it is necessary to design a new long-span bridge structural health monitoring method based on the Internet of Things RFID technology.That is,the health monitoring sensor node is deployed by using the RFID technology of the Internet of Things to process the health monitoring data of the bridge structure,so as to realize the health monitoring of the long-span bridge structure.The experimental results show that the designed long-span bridge structural health monitoring method has high degree of conformity between the vertical shape variables of main beams monitored at different monitoring points and the actual vertical shape variables of main beams,which proves that the designed long-span bridge structural health monitoring method has good accuracy and certain application value.
