Study on Wireless Sensor Network for SHM

Abstract

结构健康监测(SHM)是指利用现场的无损传感技术,分析通过包括结构响应在内的结构系统特性,达到检测结构损伤或退化的一些变化。传统的有线监测方式,由于其电缆布线的需要,随着网络规模的扩大,有线网络中传输线的成本急剧增加,供电电源困难、节点安装拆卸繁琐的缺点日益突出,无线监测拥有安装维护便捷快速、网络拓扑灵活等特点,正成为一种趋势,有着广阔的应用前景。 基于结构健康监测以及自动损伤识别的无线传感器网络(WSN)的设计必须满足:低功耗、低复杂度、覆盖范围广、簇首计算能力强、适当的传输速率五个要求。目前国内外用于结构健康监测的无线传感网络大多是限制在节点数比较少的单跳网络,并且基于损伤识别应用的无线...Structural Health Monitoring (SHM) is the use of on-site non-destructive sensor technology, which analysis of system structural characteristics including structural response, to detect structural damage or degradation of some changes.
