在分析了计轴传感器现状的基础上,提出了一种接近开关式计轴传感器的设计方案。该传感器利用涡流原理探测车辆位置,对轨道中进出的车辆进行计数,并将计数结果传送给监控分站,以供监控系统安全地调度车辆。文中详细介绍了该计轴传感器的结构,给出了列车位置传感器与计轴数据处理电路的电路原理图,介绍了相应的软件设计。
Based on the analysis of the status of the axle counting sensor, a design scheme of the proximity switch type axle counting sensor is proposed. The sensor uses the eddy current principle to detect the position of the vehicle, to track the vehicles entering and leaving the track, and transmits the counting result to the monitoring substation for the monitoring system to safely schedule the vehicle. In this paper, the structure of the axle counting sensor is introduced in detail, and the circuit schematic diagram of train position sensor and axle counting data processing circuit is given, and the corresponding software design is introduced.
