Abstract

The present invention aims at solving the problems of train identification loss which causes automatic invalid of operation control and unable to automatically distinguish train block in existing urban rail train operation. The present invention invents a space-time two-dimension train tracking method and consists of the following six steps: train positioning, train inertial distinguishing, stepping distinguishing, system dispatching, train distinguishing deletion and real-time monitoring; the present invention solves the problem of accuracy and promptness in the operation process of the train and orderly dispatches the whole system, timely eliminates train fake identification number, eliminates train monitoring blind area and automatically decides train block accidents. Therefore, the present invention is suitable to be applied in train operation tracking in any block mode in urban rail traffic.

Description

technical field [0001] The invention relates to a method for realizing two-dimensional train tracking, in particular to a two-dimensional train tracking method compatible with both time and space dimensions in urban rail transit, specifically a space-time two-dimensional train tracking method. Background technique [0002] At present, the operation of the automatic train supervision system (ATS) of urban rail transit is the top layer of the entire urban rail transit automatic control system, and it is the command center of the entire subway operation. To meet the needs of operation, realize the automation of train operation management. The basic functions of the ATS system are: train tracking, route setting, train adjustment, timetable management, equipment management, data recording, input and output, etc. [0003] In the rail transit ATS system, train tracking is the basis for realizing the functions of the ATS system. Its task is to reproduce the operation of the train w...
