摘要
目前,对于大型桥梁结构健康监测的无线传感系统的应用研究正处于探索阶段,本文根据大型桥梁结构健康监测的需要,提出一种基于多跳的簇型无线传感器网络架构,以支持长距离、多测量点的大型桥梁结构健康监测。论文在介绍该系统的软硬件构架的基础上,重点阐述以备用中继节点方式实现网络自愈功能,使系统具有一定的自我修复功能,以提高系统的稳定性。
The study on the application of wireless sensor system for monitoring structural stability of long-span bridge is still at a primary stage.In oreder to meet the requirement for bridge structural stability monitoring,this paper puts forward a framework of cluster-based multi-hop wireless sensor network,which can help to monitor structural stability of long-span bridge with multiple measuring points.By the introducing the hardware and software structure of the system,this paper elaborates on backup relay node to realize network self-repair function and improve the stability of the system.
