The invention discloses a track axle counting sensor and an anti-interference counting method thereof, and relates to the technical field of track axle counting sensors, and the track axle counting sensor comprises a sleeper and a counting assembly. In the using process of the pressure strain device, the processing circuit arranged in the circuit board outputs the physical deformation sensed by the pressure strain device when the railway vehicle passes through the steel rail and an analog signal used for representing the physical deformation, and the analog signal is finally converted into a digital signal after amplification shaping and clutter filtering, so that signal processing can be facilitated; the weight of each axle of the railway vehicle is calculated according to the waveform of the digital signal through a calculation unit arranged in a circuit board, the weight of each axle of the railway vehicle is compared with a preset weight threshold value through a logic judgment unit, and when the waveform corresponding to the axle of the railway vehicle conforms to the preset waveform, it is determined that the axle of the railway vehicle passes. And counting the axles through which the railway vehicle passes, and generating an axle counting signal according to the counting result of the axles through which the railway vehicle passes.

    本发明公开了一种轨道计轴传感器及其抗干扰计数方法,涉及轨道计轴传感器技术领域,包括枕木和计数组件。本发明使用过程中,通过电路板内置处理电路将轨道车辆通过钢轨时压力应变装置所感应到的物理形变,输出用于表征该物理形变的模拟信号,并经过放大整形和过滤杂波后最终转换为数字信号,能够有利于信号的处理,再经过电路板内置计算单元,根据数字信号的波形,计算出轨道车辆每根车轴的重量,再由逻辑判断单元对车轴的重量与预设重量阈值进行比较,轨道车辆的车轴对应的波形符合预设波形时,确定轨道车辆的车轴通过,并对轨道车辆通过的车轴进行计数,再根据轨道车辆通过的车轴的计数结果,生成车轴计数信号。
