Problems solved by technology
However, there are often occluded areas such as stations, bridges, and tunnels on the driving route of rail vehicles. These occluded areas will affect the positioning accuracy of the global navigation satellite system, and even make the positioning of the global navigation satellite system unavailable.
Therefore, how to solve the problem that the positioning accuracy of the global navigation satellite system is low when the location is blocked, or even the positioning is not available, which leads to the problem that the rail vehicle cannot be accurately positioned has become an urgent technical problem in the field of rail vehicle positioning technology.

The invention relates to a rail vehicle positioning system and method. The rail vehicle positioning system comprises a transponder set, a vehicle-mounted reader and an information conversion module, the transponder set comprises a plurality of passive transponders, the passive transponders are installed at different positions of a driving route, and the vehicle-mounted reader and the information conversion module are arranged on a rail vehicle. The passive transponder is used for storing mileage characterization information to characterize the corresponding kilometers of the installation position of the passive transponder on the driving route. The vehicle-mounted reader is used for reading the mileage characterization information stored in the target passive transponder and sending the mileage characterization information to the information conversion module, and the target passive transponder is a passive transponder installed at the current vehicle position in the running process of the rail vehicle. And the information conversion module is used for obtaining the positioning information of the rail vehicle according to the mileage characterization information. According to the rail vehicle positioning system and method provided by the embodiment of the invention, accurate positioning of a shielded section can be realized.
Description
technical field [0001] The present application relates to the technical field of rail vehicle positioning, in particular, to a rail vehicle positioning system and method. Background technique [0002] At present, the positioning of rail vehicles is mainly realized by using the global navigation satellite system. However, there are often occluded areas such as stations, bridges, and tunnels on the driving route of rail vehicles. These occluded areas will affect the positioning accuracy of the global navigation satellite system, and even make the positioning of the global navigation satellite system unavailable. Therefore, how to solve the problem that the positioning accuracy of the global navigation satellite system is low when the location is blocked, or even the positioning is not available, which leads to the problem that the rail vehicle cannot be accurately positioned, has become an urgent technical problem in the field of rail vehicle positioning technology.
