The invention discloses a multi-sensor train positioning method and system. The method comprises the following steps: acquiring respective measurement data of an inertial measurement unit, a wheel speed sensor and a satellite data processing unit on a train; the inertial measurement unit is used as a reference system, the wheel speed sensor and the satellite data processing unit are used as calibration systems, and the measurement data are fused to obtain the current position of the train; and determining the current section of the train according to the current position and the electronic map of the train track. According to the embodiment of the invention, the train can be accurately positioned without a ground transponder.

    本发明公开了一种多传感器的列车定位方法和系统。该方法包括:获取列车上惯性测量单元、轮速传感器和卫星数据处理单元各自的测量数据;以所述惯性测量单元作为参考系统,所述轮速传感器和卫星数据处理单元作为校准系统,对所述测量数据进行融合得到所述列车的当前位置;根据所述当前位置和列车轨道的电子地图,确定列车当前所在区段。本发明实施例可以实现无地面应答器情况下的列车准确定位。
