The utility model discloses a measurement system of vertical displacement of rail. Wherein, this system includes: weak magnetic path is installed in the rail, the magnetic induced shrinkage or elongation displacement meter is connected in the sleeper of rail for the magnetic field of the weak magnetic path of response, communication relationship is establish with the magnetic induced shrinkage orelongation displacement meter to the collector for adopting magnetism collection and sending the signal of telecommunication that flexible displacement meter sent, wherein, the signal of telecommunication is used for signifying vertical displacement of rail. The utility model provides a prior art adopt contact or manual methods of measurement to lead to the coarse technical problem of the verticaldisplacement measurement of rail. 本实用新型公开了种钢轨纵向位移的测量系统。其中，该系统包括：弱磁块，安装于钢轨；磁致伸缩位移计，连接于钢轨的轨枕，用于感应弱磁块的磁场；采集器，与磁致伸缩位移计建立通信关系，用于采集磁致伸缩位移计发送的电信号，其中，电信号用于表征钢轨的纵向位移。本实用新型解决了现有技术采用接触式或手动的测量方法导致钢轨纵向位移测量不精确的技术问题。
