Method and device for judging advancing direction of train in rail transit

The invention discloses a method and a device for judging the advancing direction of a train in a rail transit. The method comprises the following steps: determining an area where a vehicle-mounted wireless communication terminal is located, and dividing the coverage range of a base station on an operation rail into a near field and a far field according to the coverage distance of a reverse signal; in the near field, enabling the terminal to receive a forward signal or a reverse signal sent by the base station; in the far field, enabling the terminal to receives a forward signal sent by the base station; and according to different areas where the vehicle-mounted wireless communication terminal is located and distance information and received signal strength information obtained through measurement, judging the advancing direction of the train. Through the train positioning method provided by the invention, the train position can be quickly and accurately determined, the method is simple and efficient, hardwa
