摘　　要：提出了一种新型的桥梁结构健康远程监控系统,能满足恶劣工作环境、抗电磁场干扰、抗腐蚀、抗潮湿等要求,并可通过互联网对大型桥梁结构健康进行可靠的远程监控。系统由布设在结构监控点处进行应变和温度监测的光纤光栅传感器、对传感信号进行解调的光纤光栅解调仪、对传感数据进行采集处理的软件模块和将监控数据通过互联网传输到监控中心的传输模块以及在线远程监控模块等部分组成。This paper presented a novel system for bridge structure health remote monitoring. The system could adapt to the poor working environment, anti-jamming, corrosion and moisture resistance. It also could carry out a reliable remote monitoring to the large-scale bridge structure health through the lnternet. The system could be divided into five parts： fiber grating strain sensors and temperature sensors on monitoring points, an optical sensing interrogator for sensory signal ＇ s demodulation, a soft module for data acquisition and processing, a transmitting module for data transmit to central server through the Internet and on-line remote monitor and control module.
