Abstract

The invention provides a positioning method, device and system of a train, and a storage medium. The positioning method of the train comprises the steps that the initial position and the train speed of the train are obtained, and the real-time position of the train is determined according to the initial position of the train and the result of time integration operation of the train speed; identification information of a base station in communication connection with the train at the first moment is obtained, and signal strength of the base station is determined; and according to the pre-storedcorresponding relationship between the signal strength and the position of the base station, the position corresponding to the signal strength of the base station is determined; and the real-time position of the train is corrected through the position corresponding to the signal strength of the base station, and thus the real-time position of the train at the first moment is obtained. The train ispositioned through the base station beside a track, the positioning result of time integration of the speed is corrected, the positioning efficiency and positioning accuracy of the train during breakdown of a signal system can be improved, and the traveling safety of the train is guaranteed.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a train positioning method, device, system and storage medium. Background technique [0002] At present, the way to realize the train positioning is mainly to realize the positioning through the speed measurement of the speed measuring motor, radar and other sensors, and to realize the correction of the train position through the transponder after a further distance. Or, the rough positioning of the section can be achieved through the aid of axle counting or track circuits, and then the rough positioning can be uploaded to the central station for display through a dedicated network such as wireless local area network (WLAN) or long-term evolution (LTE) of universal mobile communication technology. [0003] Therefore, the existing train positioning communication completely depends on the station and trackside equipment. If the signal system fails (such as a single or multi-ca...
