The invention discloses a track axle counting system based on a fiber grating sensor, the track axle counting system can move on the surface of a steel rail, the steel rail is provided with the fiber grating sensor, the track axle counting system comprises two moving seats used for simulating wheels of a train, the number of the moving seats is two, the two moving seats are symmetrically arranged on two sides of the steel rail, and the two moving seats are connected through a telescopic joint; the laser transmitter is arranged corresponding to the fiber grating sensor, the laser transmitter is mounted at the bottom of the moving seat, and the laser transmitter is used for measuring the distance between the fiber grating sensor and the bottom of the moving seat; the positioning roller assembly is arranged corresponding to the steel rail, the positioning roller assembly is installed on the lower portion of the telescopic joint, and the position of the positioning roller assembly on the telescopic joint can be adjusted according to the width of the steel rail. The situation that electric signals are interfered by electromagnetic signals generated by trains and rails due to the fact that an electromagnetic induction type detection mode is adopted in the prior art is avoided.

    本发明公开了一种基于光纤光栅传感器的轨道计轴系统,其可在钢轨表面移动,钢轨设置有光纤光栅传感器,所述轨道计轴系统包括:用于模拟列车的车轮的移动座,移动座数量有两个并对称设置于钢轨两侧,两移动座通过伸缩节连接;与所述光纤光栅传感器对应设置的激光发射器,所述激光发射器安装在所述移动座的底部,激光发射器用于测量光纤光栅传感器与移动座底部之间的距离;以及定位滚轮组件,所述定位滚轮组件对应钢轨设置,定位滚轮组件安装在所述伸缩节下部,且定位滚轮组件可根据钢轨的宽度调节在伸缩节的位置。本发明避免了现有技术采用电磁感应式的检测方式,而导致的电信号受到火车及铁轨产生的电磁信号干扰的情况发生。
