Embodiment Construction

[0081] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0082] This embodiment provides a high-precision train positioning system. The train positioning system includes an automatic train protection system, a temporary speed limit server (TSRS) and a Beidou ground-based augmentation system. The automatic train protection system can be a vehicle-mounted ATP, wherein the vehicle-mounted ATP is controlled by Computer, orbit information receiving unit, transponder information receiving unit, brake interface unit, recording unit, man-machine interface, speed s...

Abstract

The present invention provides a high-precision train positioning method and system. The method includes: the train automatic protection system receives train satellite positioning data, forms a first information packet and sends it to a temporary speed limit server; the temporary speed limit server receives the first information packet for analysis , form the second information packet and send it to the Beidou ground-based augmentation system; The information packet is analyzed and formed into a fourth information packet and sent to the automatic train protection system; the automatic train protection system receives the fourth information packet, and corrects the satellite positioning data according to the fourth information packet, so as to solve the problem that the existing train positioning accuracy is low, thereby It may lead to the occurrence of vicious accidents, and due to the continuous investment of a large amount of funds in maintenance, technology, spare parts, etc., it will lead to high operating costs.

Description

technical field [0001] The invention relates to the technical field of train positioning, in particular to a high-precision train positioning method and system. Background technique [0002] The CTCS-2 / 3 level train control system currently widely used in my country's railways uses ground transponders to assist wheel sensors to realize train position status awareness, and uses track circuits to realize train occupancy checks. First of all, when the track circuit and other equipment encounter bad weather conditions or geological disasters, it is very easy to cause the blockage system to fail, so that the track circuit cannot correctly transmit the information of the signal machine, thus causing an accident. Secondly, the realization of train position correction based on transponders also faces the problem of system cost caused by a large number of ground equipment. In particular, the northwest region of my country is located in a high-altitude plain area, with sparsely popul...
