Abstract

The invention provides a train positioning method and device, electronic equipment and a storage medium. The method comprises the steps of receiving satellite positioning data, and calculating a first running distance of a train under satellite positioning according to the satellite positioning data; acquiring test data of a train speed measurement and distance measurement system, and calculating a second running distance of the train measured by the speed measurement and distance measurement system based on the test data; and if the difference value between the first running distance and the second running distance is within an allowable range, determining train position information according to the satellite positioning data. According to the train positioning method and device, the electronic equipment and the storage medium provided by the invention, the satellite positioning data exceeding the allowable error range are identified through the cooperation of satellite positioning and the train speed measurement and distance measurement system, accurate train positioning is obtained, and the positioning safety of the train is ensured.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train positioning method, device, electronic equipment and storage medium. Background technique [0002] For railway trains, accurate positioning can effectively ensure the safety of trains when they are tracking and running. At present, satellite positioning technology relies on its advantages such as wide coverage, no dependence on ground equipment, and no time accumulation error. It has become an industry trend to be widely used in train operation control systems. [0003] There are precedents for using satellite positioning technology to achieve train positioning on railway trains, but satellite positioning equipment needs to receive electromagnetic wave signals from satellites in the sky to calculate its own longitude and latitude, which will be affected by factors such as obstructions and the stability of the earth's ionosphere. When using this technology, a certain...
