The application discloses a positioning method, device and system based on terrestrial magnetism information; the method is applied to a server, and the server is connected with a wireless terrestrial magnetism sensor through a receiver; in the method, when a train passes a wireless terrestrial magnetism sensor detection zone, the wireless terrestrial magnetism sensor generates a terrestrial magnetism signal, and the receiver sends the terrestrial magnetism signal to the server; the server uses the terrestrial magnetism signal to determine a mounting position of the wireless terrestrial magnetism sensor; the mounting position of the wireless terrestrial magnetism sensor is taken as the train locating position; a wagon number identification system of the train locating position is triggered, and obtains the wagon number of the train, thus positioning the train according to the wagon number and the train locating position. The application uses the server, the receiver and the wireless terrestrial magnetism sensor to position the train, so no manual operation is needed, thus reducing manpower resource waste.
