Embodiment Construction

[0024] A method for monitoring line status based on the regional control system in the CBTC system proposed by the present invention will be described in detail below with reference to the drawings and embodiments.

[0025] Such as figure 1 Shown, a kind of method of the present invention based on the regional control system monitoring line state in the CBTC system comprises the following steps:

[0026] S1. The area control system in the CBTC system obtains the position information of the CBTC train through the interaction with the on-board equipment, and obtains the occupancy information of the logical sections contained in the axle counting section through the interaction with the interlocking equipment, and obtains it by querying the line database line information. The occupancy information of the logical section (the minimum description unit of the line) included in the axle counting section includes three types: the logical section is occupied by a CBTC train, the logic...

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...
