Method for monitoring track state based on zone control system in CBTC (communication based train control) system

Abstract

The invention relates to the technical field of a train operation control system, which discloses a method for monitoring the track state based on a zone control system in a CBTC (communication based train control) system. On one hand, the method takes the zone control system as rail-side equipment, performs differentiation and description through position information of a CBTC train obtained from vehicle-mounted equipment, occupation information of a logic section included in an axle counting section obtained from interlocking equipment, and track situations, updates the track state in real time, realizes accurate monitoring of the track occupation state, can meet the description requirement of mixed operation on a track, and is suitable for the requirement of mixed operation of trains in different levels in a CBTC system. On the other hand, the method increases checking means of train occupation conditions of tracks, processes the guide safety side for abnormal track occupation states, and guarantees the updating accuracy and safety of track states, thereby improving the operation efficiency of the whole CBTC system, and guaranteeing the efficient, safe and reliable operation of the whole CBTC system.

Description

technical field [0001] The invention relates to the technical field of train operation control systems, in particular to a method for monitoring line status based on an area control system in a CBTC system. Background technique [0002] The regional control system is an important part of the CBTC (Communication Based Train Control System, train control system based on communication technology) system. Track occupancy / vacancy information, calculate and generate mobile authorization for communication trains within its control area, to ensure the safe operation of communication trains within its control area, it has the ability to manage trains under various train control levels and driving modes, and it is reliable Security and availability are related to the smooth operation and operational efficiency of the entire CBTC system. [0003] The CBTC system configures the axle counter as the secondary train occupancy detection equipment, which can continuously detect the occupanc...

AI Technical Summary

Problems solved by technology

However, under the traditional fixed block or quasi-mobile block system, the train operation control system cannot know the specific location of the train in the zone, cannot accurately monitor the line occupancy status, and does not differentiate and describe the train operating conditions on the line. On this basis, the control of train operation requires a large safety interval between trains, which will affect the efficiency of the line.
