Train positioning method and system

Abstract

The invention relates to a train positioning method and system. The method comprises the following steps: acquiring message information in an action range; and positioning according to the message information and the running distance of a train. According to the train positioning method and system provided by the invention, message information can be compiled in real time in the action range, and the position and direction of the train can be obtained in real time. And the vehicle-mounted equipment calculates the relative position of train operation through a special control message, memorizes and restarts and then provides position information, so that the function of automatically converting into complete monitoring after starting is realized.

Description

technical field [0001] The invention belongs to the field of train control in the railway industry, and in particular relates to a train positioning method and system. Background technique [0002] The train operation signal control systems (CTCS-2 and CTCS-3) used in my country's high-speed passenger dedicated lines all rely on ground balises. The ground balise (referred to as balise) is a vehicle-ground information transmission technology that provides key line data (called messages) related to driving safety to the vehicle control device at a key position on the line to achieve automated high-speed safety. Point device for operational control. During the operation of railway trains, the transponder is one of the important basic equipment in the train operation control system. As balises are widely used in railway operation control, the maintenance of balises becomes more and more important. In order to facilitate the user to rewrite and maintain the transponder message...

AI Technical Summary

Problems solved by technology

However, the above-mentioned virtual transponder has the following problems, that is, it is necessary to add a message storage unit on the train, and the message information is stored in advance, which cannot be compiled in real time, and the virtual transponder cannot be dynamically set.

[0006] On the other hand, the existing physical balise is a balise installed on site. If the message is variable, ground control equipment needs to be installed, and cables need to be laid. All trains can receive the message, which requires outdoor construction and maintenance. The controller cannot be dynamically set, it is impossible to compile messages in real time, and it is impossible to obtain the train position in real time

[0007] Therefore, there is an urgent need to provide a train positioning method and system, which can solve the technical problems in the prior art that there are too many balises in the balise group when the train is positioned, the message information cannot be compiled in real time, and the train position cannot be obtained in real time
