Problems solved by technology

[0003] However, the positioning method using the wheel axle counter will cause the cumulative error of the mileage due to wheel idling, skidding and car body serpentine caused by the wear of the wheel, which needs to be corrected in time. Due to the high cost of transponder laying and maintenance, the positioning accuracy depends on Transponder deployment density, but in practical applications, the deployment density of transponders cannot reach infinity, and it is impossible to grasp the change trend of line infrastructure in real time. Therefore, it leads to the technical problem of low positioning accuracy of rail transit trains

The method includes: acquiring an optical signal emitted by an optical emitting module, and image information including the optical emitting module; The image information determines the position of the rail transit train. The rail transit train positioning method, device and system provided by the embodiments of the present invention apply optical communication and image processing technology to the rail transit train positioning, thereby improving the train positioning accuracy.

Description

technical field [0001] The present invention relates to the technical field of rail transit, and in particular, to a method, device and system for locating a rail transit train. Background technique [0002] At present, train positioning mostly adopts the combination of the speed measurement positioning of the axle counter and the query-transponder positioning. During the running of the train, when the interrogator passes the transponder, the transponder detects the interrogator through electromagnetic induction. After the connection is successful, the transponder sends the information stored in the interrogator to the interrogator. [0003] However, the positioning method using the axle counter will cause the accumulated error of the mileage due to the wheel idling, slippage and the serpentine shape of the car body caused by the wear of the wheel, which needs to be corrected in time. Due to the high cost of transponder laying and maintenance, the positioning accuracy depend...
