基于WSNs和移动Agent的桥梁结构健康监测研究

针对桥梁结构大而复杂、传感器数目种类多、损伤形式多样等特点，引用无线传感器网络（WSNs）和移动Agent技术。以实际桥梁结构为研究对象，采用以CC2530为核心的无线传感器节点采集桥梁结构相关数据；利用移动Agent的移动性，迁移和访问网络节点，完成对节点数据的收集和处理；运用ZigBee无线通信协议将数据传送至网关节点加以处理；通过GPRS无线通信方式将最终数据送至监测中心，确定桥梁的健康状况。结果表明：该系统符合设计要求，且监测数据可靠，具有应用和推广价值。

Study on bridge structural health monitoring based on WSNs and mobile agent

Aiming at characteristics of bridge structure is large and complicated, there are large amounts of and kinds of sensors, and damage in a variety of forms,wireless sensor networks（WSNs） and mobile agent technologies are adopted. Real bridge structure is taken as research object,adopting CC2530 as the core of the WSNs nodes to collect relevant bridge structure data. Using mobility of mobile agent, migrate and access to network nodes to complete collection and processing of the nodes data. Using Zig Bee wireless communication protocol to transfer data to gateway node for processing. Through GPRS wireless communication mode, send eventual data to monitoring center to determine health status of bridge. The results show that the system meets design requirements, and monitoring data is reliable, it has application and popularization value.
