Problems solved by technology

[0009] However, the above methods 4 and 5, although continuous positioning without cumulative error can be obtained, they still face the problem of inability to locate under severe signal conditions such as tunnels, and multiple sets of satellite navigation systems can only improve usability and accuracy. It is easy to receive interference, or false satellite signal spoofing has not been effectively solved

Abstract

The invention discloses a Beidou / GPS combination based safe train locating method and system. A Beidou satellite navigation system is combined with a GPS satellite navigation system, a ground differential station system, a train-mounted speedometer and a ground responder system are combined in use, and safe location of a train is realized. The system of the invention can coexist and be compatiblewith existing train locating systems, and satellite navigation is safer in the aspect of train locatin.

Description

technical field [0001] The invention relates to the technical field of railway signals, in particular to a method and system for safe positioning of trains based on Beidou / GPS combination. Background technique [0002] The railway signal system is responsible for controlling the operation of trains on the line. Usually, methods such as time separation or space separation are used to ensure that the trains maintain a fixed or variable interval between each other and realize the tracking operation of the trains. In the above control, it is necessary to obtain the current position of each train and give corresponding authorization instructions in real time to ensure that the train does not collide with the rear. [0003] At present, my country's railway train positioning mainly has the following methods: [0004] 1. Based on the connection of the track circuit or axle counting equipment installed on the trackside with the ground control system, the train positioning is realize...
