The bridge structure monitoring technology can ensure the safe operation of bridge,and protect life and property safety of the masses. To meet the need of remote data monitoring for the bridge structure and realize the cyberization of bridge monitoring,the system is improved on the basis of the bridge structure testing system of Bridge Diagnostics Inc.(BDI),and a set of wireless data transmission,analysis and memory module is studied and designed,in which the LabVIEW is regarded as the development platform,and the wireless network technology,virtual instrument technology and bridge structure monitoring technology are combined. The module can realize the wireless transmission and storage of bridge sensor date. The system has strong adaptability and high stability,and provides a feasible solution for the monitoring of small-and medium-size bridge.%桥梁结构监测技术能有效地保证桥梁的安全运营,保障人民群众的生命财产安全.为了满足桥梁结构的远程数据监测需要,实现桥梁监测的网络化,该系统在美国桥梁诊断公司(BDI)的桥梁结构测试系统的基础上加以改进,将无线网络技术、虚拟仪器技术和桥梁结构监测技术与之结合在一起,并以LabVIEW作为软件开发平台研究并设计了一套无线数据传输解析存储模块,实现了桥梁传感器数据的无线传输与存储,具有较强的适应性和稳定性,为中小型跨径桥梁的监测提供可行的解决方案.
