基于无线传输技术的野外桥梁远程健康监测及安全评估系统

Remote Health Monitoring and Safety Evaluation System for Bridge Based on Wireless Transmission Technology

针对在野外偏远山区桥梁无法运用常规监测方法和设备问题,提出了运用无线传输技术实现对桥梁的远程监测,并以封侯沟大桥为例,介绍了桥梁健康监测系统的各项功能及关键技术。该监控系统经多年运行,在安全评估结果指导下对大桥进行及时维护,使大桥仍保持了健康的使用状态,有效保证了车辆的安全通行。

This paper puts forward the remote monitoring of bridge by using wireless transmission technolo-gy,and introduces the function and key technology of the bridge health monitoring system. The monitoring system has been operated for many years,the bridge is maintained in time under the guidance of safety as-sessment results,and the bridge is still maintained in a healthy state,which can ensure the safety of the vehicle.
