Design and Deployment of Bridge Structural Health Monitoring System Based on Wireless Sensor Network

Wireless sensor network (WSN)becomes a research hotspot of structural health monitoring(SHM) with the characteristics such as convenience for remote monitoring, good fault-tolerant ability, easiness of system maintenance ,etc. In this paper, a WSN for bridge SHM is designed and deployment on the ZhengDian viaduct in Wuhan. In this deployment, 20 wireless nodes are distributed over the main span, collecting the ambient vibrations at 200Hz.The collected data agrees with theoretical models and previous studies of the bridge.
