The invention provides a train positioning method. The method comprises the following steps: arranging a voltage sensor, a current sensor and an acquisition device on a feeder cabinet of each tractionpower supply station on an operation line of a train; in the running process of a train, synchronously measuring a voltage signal and a current signal output by a feeder line of the traction power supply station where the voltage sensor and the current sensor are located by a voltage sensor and a current sensor in each traction power supply station, and uploading the voltage signal and the current signal to an upper computer through an acquisition device; and selecting the voltage and current values of the traction power supply station A closest to the head of the train and the traction powersupply station B closest to the tail of the train by the upper computer, and introducing the voltage and current values into the matrix equation in a sliding window mode to calculate the position information of the train. Only the voltage and current values of the traction substations on the two sides of the traction power supply line need to be measured, complex signal data transmission equipment does not need to be added, the structure is simple, signal system faults cannot be caused, and dangerous driving factors are not increased.

    本发明提供了一种列车定位方法。该方法包括:在列车的运行线路上的各牵引供电所的馈线柜设置电压传感器、电流传感器和采集装置;在列车的运行过程中,各牵引供电所中的电压传感器和电流传感器同步测量其所在的牵引供电所馈线处输出的电压信号和电流信号,并通过采集装置将电压信号和电流信号上传到上位机;上位机选取距离列车的车头最近的牵引供电所A和距离列车的车尾最近的牵引供电所B的电压电流值,通过滑窗方式将其代入矩阵方程计算出列车的位置信息。本发明仅需测量牵引供电线路两侧牵引变电所的电压电流值,无需增加复杂的信号数据传输设备,结构简单,不会引起信号系统故障且不增加危险行车的因素。
