The invention relates to the technical field of rail transit, in particular to a train positioning method and system and a storage medium. According to the method provided by the invention, when the train loses positioning, only the message information of one ground positioning device (100) needs to be acquired, then the current position of the train is determined according to the message information, the searched historical position and distance information are combined, path searching is carried out in an electronic map, and the path searching is carried out based on the searching direction corresponding to each path. And determining the unique driving direction indicated by each path as the current driving direction of the train. In this way, the train positioning speed is greatly increased, and the influence on normal operation of other trains on the rail is reduced.

    本发明涉及轨道交通技术领域,特别是一种用于列车定位的方法、系统及存储介质。根据本发明提供的方法,当列车失去定位后只需要获取一个地面定位设备(100)的报文信息,然后根据报文信息确定的列车的当前位置并结合查询的历史位置、路程信息以及在电子地图中进行路径搜索,基于各路径对应的搜索方向,将各个路径所指示的唯一行驶方向确定为列车的当前行驶方向。如此,极大地提高了列车定位的速度,并降低了对轨道上其他列车的正常运营的影响。
