The invention discloses a train positioning method and system, a storage medium and electronic equipment. The method comprises the following steps: acquiring an initial position of a train; acquiring the linear speed of the train wheel set, and determining the current running speed of the train according to the linear speed; the periodic running distance of the train is determined according to the current running speed; determining a second position of the train at the current moment according to the initial position and the periodic running distance; beidou position information collected by a Beidou positioning system is obtained, and mileage information is determined according to the Beidou position information; determining a third position of the train at the current moment according to the mileage information; and updating the position of the train at the current moment according to the second position and the third position. On the basis of an existing multi-sensor fusion scheme, Beidou equipment is added to participate in information fusion, the defects of an existing train positioning technology are overcome, and the positioning precision and reliability of a heavy haul railway train can be effectively improved.

    本申请公开了一种列车定位方法、系统、存储介质及电子设备。所述方法包括:获取列车的初始位置;获取列车轮对的线速度,并根据线速度确定列车的当前运行速度;根据当前运行速度确定列车的周期走行距离;根据初始位置和周期走行距离确定列车在当前时刻的第二位置;获取通过北斗定位系统采集的北斗位置信息,并根据北斗位置信息确定里程信息;根据里程信息确定列车在当前时刻的第三位置;根据第二位置和第三位置更新列车在所述当前时刻的位置。在现有多传感器融合方案的基础上增加了一种北斗设备参与信息融合,弥补了现有列车定位技术的不足,可有效地提高重载铁路列车的定位精度和可靠性。
