The invention belongs to the technical field of rail transit, and relates to an axle counting system of a wheel sensor, which comprises a wheel sensor, a junction box and an axle counting host, the wheel sensors are used for detecting wheel rims of train wheels and converting detected signals into digital signals from analog signals, the wheel sensors are laid on a rail, a junction box is arranged near each wheel sensor, the junction boxes correspond to the wheel sensors in a one-to-one mode, and each junction box is connected with the junction box adjacent to the front junction box and the rear junction box. All junction boxes along the line are cascaded and then are connected to the axle counting host. According to the axle counting system, the cable laying cost can be reduced, the transmission data size is large enough, interference is not prone to occurring, reliability is high, the maximum transmission distance can reach 8 km, the influence of signal line resistance is avoided, data are transmitted to the host through the multiple sensors in a bus mode, and the reliability is high. And the signal transmission of eight sensors can be realized by only one group of cables of the sensors, so that the cable cost is saved.

    本发明属于轨道交通技术领域,涉及一种车轮传感器的计轴系统,包括:车轮传感器、接线盒和计轴主机;车轮传感器,用于探测列车车轮的轮缘,并将探测的信号由模拟信号转换为数字信号,车轮传感器敷设在铁轨上,在每个车轮传感器附近设置一接线盒,每个接线盒与车轮传感器一一对应,且每个接线盒与其前后相邻的接线盒连接,将沿线的所有接线盒级联后,连接到计轴主机。该计轴系统能够降低电缆铺设成本、传输数据量足够大且不容易受到干扰、可靠性高,其最大传输距离可达8km,不受信号线阻大小的影响,多个传感器之间采用总线的方式将数据传输至主机,只需一组传感器的线缆即可满足8个传感器的信号传输,节省了线缆成本。
