The invention relates to the technical field of rail transit, in particular to a train positioning method and system and a storage medium. Ground positioning devices (21, 22) are arranged only on one side of the track section (2) at the same position in the default running direction of the track section (2), and a vehicle-mounted antenna (13, 14) arranged on each of the two transverse sides of the train (1) can only communicate with the ground positioning devices (21, 22) arranged on the same side. In a non-positioning state of the train (1), vehicle-mounted antennas (13, 14) on the two sides are started to obtain first message information from ground positioning devices (21, 22), and whether the orientation of the vehicle-mounted antenna receiving the first message information relative to an activated train head of the train (1) is the same as the orientation of the ground positioning devices relative to a default running direction of a track section (2) is judged. In this way, the time required for positioning the train (1) is greatly shortened.

    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。轨道区段(2)上在其默认运行方向上的同一位置处仅在其一侧设置有地面定位设备(21、22),以及列车(1)在其横向的两侧各设置的一车载天线(13、14)仅能与置于同侧的地面定位设备(21、22)通信。在列车(1)无定位状态下开启两侧的车载天线(13、14)以获取来自地面定位设备(21、22)的第一报文信息,并通过判断收到第一报文信息的车载天线相对于列车(1)的激活车头的方位与地面定位设备相对于轨道区段(2)的默认运行方向的方位是否相同,以确定列车(1)的当前行驶方向,如此,极大地缩短了列车(1)定位所需的时间。
