The system comprises a grating array sensing optical cable and a tracking sensing module, the tracking sensing module is electrically connected to the grating array sensing optical cable and is used for acquiring vibration signals of two adjacent acquisition periods, and then the tracking sensing module is used for receiving the vibration signals of the two adjacent acquisition periods according to the vibration signals of the two adjacent acquisition periods. The method comprises the following steps: acquiring a train running state according to the train running state, acquiring a train running distance if the train running state is one of forward running and reverse running, and acquiring a judgment result that the reverse behavior of the train is retreating or turning back according to the train running distance. Compared with the prior art, the system has the advantages that monitoring of train movement conditions is achieved through the full-time and full-domain characteristics of the grating array sensing optical cables, meanwhile, tracking judgment of train retreating and turning-back is achieved through vibration signals of two adjacent collection periods, and a functional basis is provided for achieving the train movement block function.
本发明涉及一种基于光栅阵列的列车退行折返追踪系统及追踪方法,包括光栅阵列传感光缆和追踪感知模块,追踪感知模块电连接于光栅阵列传感光缆,用于获取两个相邻采集周期的振动信号,然后根据两个相邻采集周期的振动信号,得到列车行进状态,列车行进状态包括正向运行和反向运行中的一种,若列车行进状态为反向运行,则获取列车反向运行距离,再根据所述列车反向运行距离,得到列车的反向行为是退行还是折返的的判断结果。相比于现有技术,本发明通过光栅阵列传感光缆全时全域的特性,实现了列车运动情况的监控,同时利用两个相邻采集周期的振动信号,实现了列车退行和折返的追踪判别,为实现列车移动闭塞功能提供了功能基础。
