Satellite positioning system suitable for heavy-load moving blockage

Abstract

The embodiment of the invention provides a satellite positioning system suitable for heavy-load moving blockage. The satellite positioning system comprises ground station equipment, vehicle-mounted equipment and a satellite. The ground station equipment comprises a satellite differential base station and a temporary speed limit server. The vehicle-mounted equipment comprises a moving blockage host. The satellite differential base station obtains the differential information arranged according to a first a positioning position represented by the first positioning information, and the pre-obtained real position of the satellite differential base station. The temporary speed limit server receives the differential information, and forwards the differential information to the moving blockage host. In this way, the moving blocking host can correct the second positioning information of a train according to the differential information so as to obtain the real position of the train. The secondpositioning information is sent by the satellite. The satellite positioning system provided by the embodiment of the invention is suitable for heavy-load moving blockage. The system is not limited tospecific scenes and can obtain the accurate positioning position of the train.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transportation, and in particular to a satellite positioning system applicable to heavy-duty mobile blocks. Background technique [0002] Positioning technology is one of the most important technologies in the heavy-duty mobile blocking system, and its accuracy and practicability determine the control effect of the heavy-duty mobile blocking system. [0003] The existing technology obtains the fixed position of the train through track equipment (such as transponders), and then obtains the average speed of the train, and determines the real-time position of the train according to the average speed and fixed position, but this method is limited to some specific scenarios, for example: only installation The fixed position of the train can only be obtained with a transponder, but the transponder is expensive and not widely used; in emergencies such as train power outages, the tr...
