Zone searching method and system

Abstract

The invention provides a zone searching method and system. The zone searching method comprises the steps that S0, an electronic map is built according to a line description mode in advance; S1, a starting kilometer post to be searched, a terminating kilometer post to be searched and a searching direction are obtained; S2, a logical zone, where the starting kilometer post to be searched is located, in the electronic map is searched, and the logical zone identify number of the logical zone is recorded; S3, a next logical zone of the current logical zone is searched in the searching direction, and the logical zone identify number of the next logical zone is recorded; S4, whether a terminating kilometer post of the next logical zone in the searching direction is smaller than the terminating kilometer post to be searched or not is judged, if yes, the S3 is carried out, and if not, the S5 is carried out; S5, searching is ended, the recorded logical zone identify numbers form a sequence of the logical zone identify numbers according to the sequence of recording, and the sequence of the logical zone identify numbers is output. By means of the zone searching method and system, potential safety hazard caused when a train passes through a corresponding track line can be reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a section search method and system. Background technique [0002] The urban rail transit system is moving towards integration, intelligence and networking. The Automatic Train Supervision (ATS) system in the Communication Based Train Control System (CBTC) is the core of the CBTC system. An important component, mainly responsible for train supervision and operation control. The ATS system is a highly reliable and efficient automatic monitoring system developed by comprehensively adopting modern communication technology, computer technology, network technology and automatic control technology according to the train dispatching command mode and characteristics of urban rail transit. Status display, automatic control of route, automatic tracking of train operation, computer-aided preparation of operation diagram, automatic adjustment of operation diagram, automatic drawing of a...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the above description that in the prior art, method 1 marks the turnout section as a whole, and the resolution accuracy is low. When the turnout is reversed at a certain speed limit, it will also affect the train passing through the turnout in a certain direction. There are certain safety hazards when the train passes the corresponding track line

Method 2 divides the turnout section into three logical sections for identification. When setting speed limits for these three logical sections, once different temporary speed limits are set for the three logical sections, the train passing through the corresponding track There are certain safety hazards in the line
