There is provided a method for monitoring a railway track (29), the method comprising: detecting, by a distributed acoustic sensor (20), a first monitoring signal (M1) at an initial position (21) when a rail vehicle passes the initial position (21), where the distributed acoustic sensor (20) is arranged along the track (29), and detecting, by the distributed acoustic sensor (20), a second monitoring signal (M1) at the initial position (21) when the rail vehicle passes at least one predetermined position (22) along the track (29); detecting, by the distributed acoustic sensor (20), a second monitoring signal (M2) at the at least one predetermined position (22); the first monitoring signal (M1) and the second monitoring signal (M2) are compared with each other, the first monitoring signal (M1) comprising a feature (23) associated with each axle of the rail vehicle passing through the initial position (21) and the second monitoring signal (M2) comprising a feature (23) associated with each axle of the rail vehicle passing through the predetermined position (22), and comparing the first monitoring signal (M1) and the second monitoring signal (M2) with each other comprises counting, for the first monitoring signal (M1) and the second monitoring signal (M2), a feature (23) relating to an axle of a respective passing rail vehicle. Furthermore, a monitoring unit (24) for monitoring a railway track (29) is provided.

    提供了一种用于监测铁路轨道(29)的方法,该方法包括:当轨道车辆经过初始位置(21)时,由分布式声学传感器(20)在所述初始位置(21)处检测第一监测信号(M1),其中所述分布式声学传感器(20)沿轨道(29)布置,当轨道车辆经过沿轨道(29)的至少一个预定位置(22)时,由所述分布式声学传感器(20)在该至少一个预定位置(22)处检测第二监测信号(M2);相互比较所述第一监测信号(M1)与所述第二监测信号(M2),其中所述第一监测信号(M1)包括分别与经过所述初始位置(21)的轨道车辆的一个车轴相关的特征(23),并且所述第二监测信号(M2)包括分别与经过所述预定位置(22)的轨道车辆的一个车轴相关的特征(23),并且相互比较所述第一监测信号(M1)与所述第二监测信号(M2)包括针对所述第一监测信号(M1)和所述第二监测信号(M2)来计数与相应经过的轨道车辆的车轴相关的特征(23)。此外,提供了一种用于监测铁路轨道(29)的监测单元(24)。
