基于无线传感网的桥梁结构健康监测系统测试平台设计

摘要

In recent years,research on bridge structural health monitoring has attracted in-creasing attention. In this paper,we propose and design a WSN-based testbed scheme for bridge structural health monitoring system. We evaluate the performance of the testbed by simulations. Simulations results show that a hierarchical system with gateways providing power and wired communication to sensor nodes is a more viable alternative to a simple WSN equipped with large batteries,for this first phase of system exploration.%桥梁结构健康监测目前越来越受到重视和关注。本文提出了一种基于无线传感器网络的桥梁结构健康检测系统的测试平台设计方案。对该测试平台设计方案的仿真结果表明，在桥梁结构健康监测系统的调试和探索阶段，用带有能为传感器节点提供能量和有线通信的网关节点的分层传感网系统来替代一个只配备大容量电池的简易无线传感器网络是可行的。
