Design and implementation of the structure health monitoring system for bridge based on wireless sensor network

Abstract

For the shortcomings of the traditional wired way for structure health monitoring, a structure health monitoring (SHM) for bridge based on wireless sensor network (WSN) is proposed. The S-Mote node used for the WSN is designed and implemented which meets the specific hardware requirements of the structural health monitoring and supports the TinyOS as its operating system. The SHM system is deployed and tested on the ZhengDian Viaduct Bridge. In this deployment, 6 nodes are distributed over the main span, collecting the ambient vibrations at 100Hz. The collected data agrees with theoretical models and theoretical value of the bridge. © 2009 Springer Berlin Heidelberg.
