无线传感网络在结构健康监测中的应用

Structural Health Monitoring Based on Wireless Sensor Networks

将无线传感网络引入结构健康监测中。根据无线传感网络的体系结构和性能标准,提出了应用在结构健康监测里的一些特殊需求。设计了一套实验系统,在此基础上,开发出几种网络协议和应用程序,实现了多跳路由,多参数采集和网络抗毁性,并应用这些程序,协同完成了载荷定位和紧固连接件松动诊断。实验证明,无线传感网络在结构健康监测中应用前景广阔。

Structural health monitoring is an important research interestin the smart materials and structure field. This paper introduces the most promising technology, wireless sensor network and its use in the structural health monitoring. The architecture of wireless sensor network and the issues about it were introduced. An experiment system was designed for the special demand in this new field. Some routing protocols and application programs were developed, such as multi-hop routing, multi-sample and robustness. Based on these software, we implement loading location and fastener failure.
