摘　　要：为了对钢筋混凝土结构桥梁进行结构状态监测,保证桥梁的安全运行,基于物联网技术设计了一种桥梁健康远程在线监测系统,通过采集预埋的振弦式传感器信息,实时反应桥梁结构健康状态。系统采用ARM处理器STM32F407作为主控制器,采集振弦式传感器张紧力的变化以及温度信息,并通过物联网NB-IoT模块BC26将数据上传至云服务器。同时,此系统采用C/S和B/S架构搭建了远程监测系统平台,包括云服务端、手机APP终端以及浏览器客户端。通过测试表明,振弦式传感器模块测频精度高,误差精度在0.02%以内,系统整体运行稳定可靠。此系统采用了目前主流的技术方案,系统结构先进,具有很好的实用价值。In order to monitor the structure state of reinforced concrete bridge and ensure the safe operation of the bridge,a bridge health remote on-line monitoring system is designed based on the internet of things technology.Realtime response to the healthy state of bridge structure.The ARM processor STM32F407is used as the main controller.The data are uploaded to the cloud server through the internet of things NB-IoT module BC26.Meanwhile,the system uses C/S and B/S architecture to build a monitoring system platform,including cloud service terminal,mobile phone APP terminal and browser client.The test results show that the frequency measurement accuracy of the vibrating string sensor module is high,the error accuracy is less than 0.02%,and the overall operation of the system is stable and reliable.This system adopts the current mainstream technical scheme,the system structure is advanced,has the good practical value.
