The invention provides a train locating method based on the signal strength of train-ground wireless communication equipment. The method comprises the following steps: collecting the signal strength and the equipment identification of each train-ground wireless communication equipment of a train at the current position, and constructing the collected signal strength matrix of each wireless communication equipment of the train at the current position; and querying the pre-established signal strength and position database according to the signal strength matrix, obtaining an original signal strength matrix which is most similar to the signal strength matrix in the signal strength and position database, and determining the position information corresponding to the most similar original signal strength matrix stored in the signal strength and position database as the current position of the train. According to the train locating method based on the signal strength of train-ground wireless communication equipment disclosed by the invention, the signal strength of the train-ground wireless communication equipment at the current position of the train is collected, and the pre-established signal strength and position database and a matrix distance calculation algorithm are used to infer the current position of the train, so that the purpose of locating a city rail train is achieved.
Description
technical field [0001] The invention relates to the technical field of train positioning communication, in particular to a train positioning method based on the signal strength of a train-ground wireless communication device. Background technique [0002] At present, the positioning technology based on the signal strength of wireless communication equipment has been widely used in indoor positioning, mobile terminal positioning and other fields. This positioning method does not require additional equipment, and the cost is low, and the wireless positioning method only scans the wireless signal strength, does not need to access signal equipment, and the positioning can be completed by programming. [0003] At present, in urban rail transit, the subway train automatic control system uses the track and on-board equipment to locate the train in real time. There is no urban rail train positioning method based on the signal strength of the train-ground wireless communication equi...
