Rail transit train positioning method and device

The invention discloses a rail transit train positioning method and device, and the method comprises the steps: measuring a distance between a vehicle-mounted wireless communication terminal and a base station which communicates with the vehicle-mounted wireless communication terminal, and preliminarily determining the position of a train based on the measured distance, the train position being one of two positions where the distance between the terminal and the base station is the same on the operation track; and determining whether the distance measurement result is accurate or not constantly, and if the distance measurement result is wrong, correcting the train position based on the running speed of constant-speed running of the train. Through the train positioning method provided by the invention, the train position can be accurately determined, and the method is simple, efficient and easy to implement. 本发明公开了一种轨道交通列车定位方法及装置，测量车载无线通信终端与其进行通信的基站之间的距离，基于测量距离初步确定列车位置；所述列车位置为运行轨道上终端与基站距离相同的两个位置其中之一；时刻判断距离测量结果
