There is provided a method for monitoring a railway track (11), the method comprising: detecting a monitoring signal (MS) by a distributed acoustic sensor (10) arranged along the track (11), wherein each monitoring signal (MS) comprises a monitoring signal value (MSV) of the distributed acoustic sensor (10) for a first measurement section (12) and a monitoring signal value (MSV) of the distributed acoustic sensor (10) for a second measurement section (22), the first measurement section (12) being determined from the monitoring signal values (MSV) detected during the position of the rail vehicle passing through the first measurement section (12) The method includes determining a first event monitoring signal value (EV1) of the rail vehicle, determining a second event monitoring signal value (EV2) of the second measurement section (22) from a monitoring signal value (MSV) detected during a position of the rail vehicle passing through the second measurement section (22), and determining a difference value (DV), the difference value (DV) being dependent on a difference between the average relative value (ARV) and the relative value (RV), wherein the relative value (RV) is given by a relative difference between the first event monitoring signal value (EV1) and the second event monitoring signal value (EV2), and wherein the average relative value (ARV) is dependent on an average value of the relative values (RV) previously determined by the rail vehicle. Furthermore, a monitoring system (15) for monitoring a railway track (11) is provided.

    提供了一种用于监测铁路轨道(11)的方法,所述方法包括:通过沿轨道(11)布置的分布式声学传感器(10)检测监测信号(MS),其中每个监测信号(MS)包括分布式声学传感器(10)的针对第一测量段(12)的监测信号值(MSV)和分布式声学传感器(10)的针对第二测量段(22)的监测信号值(MSV)、根据在轨道车辆通过第一测量段(12)的位置期间检测到的监测信号值(MSV)来确定第一测量段(12)的第一事件监测信号值(EV1)、根据在轨道车辆通过第二测量段(22)的位置期间检测到的监测信号值(MSV)来确定第二测量段(22)的第二事件监测信号值(EV2),以及确定差值(DV),其中差值(DV)与平均相对值(ARV)和相对值(RV)之间的差相关,其中相对值(RV)由第一事件监测信号值(EV1)和第二事件监测信号值(EV2)之间的相对差给定,其中,平均相对值(ARV)与根据轨道车辆的先前通过确定的相对值(RV)的平均值相关。此外,提供了一种用于监控铁路轨道(11)的监测系统(15)。
