摘要
由于地质灾害区段没有明确的固定基准点,传统轨道变形监测方法不再适用。为此,设计了基于分布式光纤的轨道变形监测系统。本文介绍了该系统的硬件设计、软件设计、温度补偿算法等。对实测数据的分析结果表明,该系统可以消除列车通过时引起的振动和温度变化对监测数据的影响,检测精度满足设计要求。实际应用结果表明,该系统可以实时识别轨道变形,对地质灾害区段行车安全保障具有重要意义。
Because there is no clear fixed reference point in the geological disaster section,the traditional track deformation monitoring method is no longer applicable.Therefore,a track deformation monitoring system based on distributed optical fiber was designed.This paper introduced the hardware design,software design and temperature compensation algorithm of the system.The analysis results of the measured data show that the system can eliminate the influence of vibration caused by the train and temperature change on the monitoring data,and the detection accuracy meets the design requirements.The practical application results show that the system can identify the track deformation in real time,which is of great significance to the traffic safety in geological disaster areas.
