Abstract

Wireless sensor networks for Structural Health Monitoring (SHM) application have attracted much research interest over the last few years because of their great potential to monitor and maintain the safety of civil structures. This paper puts forward an effective, feasible and reliable wireless sensor system based on ZigBee technology, which can support monitoring structural health such as buildings, bridges, roads. The hardware and software structure of the monitoring system are introduced first, and then the system performance under the multi-hop network topology and TPSN algorithm are analyzed, which is used for enhancing the precision of time synchronization. The experiment shows that the performance of the wireless sensor system achieves the expected effect by comparison with the wired monitoring system.
