本研究针对中小跨径常规桥梁结构健康检测系统的硬件系统传感器选型难题,依托海南西线高速实际桥梁为基础,结合光纤光栅传感器的性能特点,从数据准确性和长期野外环境适应性两方面关键参数入手,通过运用相关零点漂移、灵敏度测试、温度漂移实验,最终解决传感器采集数据的准确性和传感器长期处于野外环境中连续测量时的数据稳定性和设备本身的耐候性等两大难题。 In this paper, based on the high-speed practical bridges in west Hainan line and the performance characteristics of FBG sensors, aiming at the problem of hardware system sensor selection for the conventional bridge structure health detection system of medium and small span, The key parameters are as follows. The two key problems are the accuracy of data collected by the sensor, the data stability when the sensor is continuously measured in the field environment, and the weatherability of the device itself by using the related zero drift, sensitivity test and temperature drift experiment.
