A railway signal axle counting system disclosed by the present invention comprises axle counting sensors, trackside devices and an indoor host, each trackside device comprises an axle counting ground trackside device and an information demodulation device, and the axle counting sensors are arranged on steel rails to identify the number of axles and the running direction of a train when the train passes by; the information demodulating equipment is used for demodulating information of each steel rail section, transmitting the information to an axle counting ground trackside device in an analog signal form for analysis to obtain trackside axle counting information, transmitting the trackside axle counting information to an indoor host, determining that the state of each steel rail section is an idle state or an occupied state by the indoor host, and demodulating the information of each steel rail section by adopting a distributed sonic sensor technology. And detecting a steel rail vibration sound wave signal by using the back scattering power of the optical cable, and obtaining a detection result of whether the steel rail is broken or not. According to the railway signal axle counting system, whether the steel rail section is occupied or not can be checked, whether the steel rail is broken or not can be automatically checked, and potential risks existing in the train running process can be conveniently found in time.

    本发明公开了一种铁路信号计轴系统,包括计轴传感器、轨旁设备和室内主机,每个轨旁设备包括:计轴地面轨旁装置和信息解调设备,计轴传感器设置在钢轨上识别列车经过时的车轴数量和列车行驶方向,并以模拟信号的形式发送至计轴地面轨旁装置进行解析,得到轨旁计轴信息,并将轨旁计轴信息发送至室内主机,由室内主机确定各个钢轨区段的状态为空闲状态或占用状态,信息解调设备采用分布式声波传感器技术,利用光缆的后向散射功率检测钢轨震动声波信号,并得到钢轨是否出现断轨的检测结果。本发明公开的铁路信号计轴系统,不仅能够对钢轨区段是否被占用进行检查,还可对钢轨是否出现断轨进行自动检查,便于及时发现列车运行过程中存在的潜在危险。
