Device and method for key point prevention and control of railway self-wheeling equipment based on satellite positioning

Abstract

The invention discloses a railway self-wheel operation equipment key point prevention and control device and a method based on satellite positioning. The device comprises a differential station and a mobile end; the differential station sends differential correction data to the mobile end; the mobile end is mounted on railway self-wheel operation equipment; a real-time distance from the railway self-wheel operation equipment to a key point needing to be prevented and controlled is calculated according to a real-time coordinate; and corresponding vehicle control actions are performed according to a real-time distance from the mobile end to the prevent and control point. The device is independent in design, has no need to communicate data with other railway systems, is low in cost, has no need to mount any ground equipment, is low in mapping workload, only needs to map the prevent and control point and the front station track direction of the prevent and control point, is high in positioning precision, adopts a multi-mode differential carrier wave phase technology, and reaches the positioning precision of lower than 1 m.

Description

technical field [0001] The invention relates to railway self-running equipment, in particular to a device and method for key point prevention and control of railway self-running equipment based on satellite positioning. Background technique [0002] In the shunting mode, railway locomotives are completely under the driver's artificial control, and there are many potential safety hazards, especially for station boundaries, catenary end points, dead lines, safety lines, fixed derailers, catenary no-stop signs, etc. At the key prevention and control points on the ground, because the automatic control of the vehicle cannot be realized, accidents frequently occurred during the shunting operation. Such as the locomotive crossing the station boundary without a certificate, the electric locomotive crossing the end of the catenary, the locomotive hitting the end line and the safety line soil block, the locomotive being equipped with a fixed derailer, and the electric locomotive parki...

AI Technical Summary

Problems solved by technology

[0010] a. The scheme is complex, and the state of the turnout must be obtained, and data communication must be carried out with other systems; it is necessary to connect the status information of the front and rear gears of the railway self-wheeling operation equipment;

[0011] b. The cost is high, and the wheel speed pulse sensor must be installed;

[0012] c. The cost of deployment is high, and the equipment stores a large amount of data. It is necessary to store detailed floor plans of all stations
