摘要
本文采用光纤分布式振动测试方法对感应光缆获取的钢轨振动和列车运行状态信号进行采集和特征分析,从而检测出通过该区段列车的运行状态和安全性能,做到实时监测并预警,为列车的安全运行和维护提供技术保障。
In this paper, optical fiber distributed vibration test method is used to collect and characterize the rail vibration and the train running status signal obtained by the sensing optical fiber cable, so as to detect the running status and safety performance of the train passing through the section,thus realizing real-time monitoring and warning, so as to provide technical support for the safe operation and maintenance of trains.
