Train tracking operation method without secondary track detection equipment and cbtc system

Abstract

The invention discloses a train tracking operation method without secondary track detection equipment and a CBTC system. The method includes: during the train running process, the VOBC of the train checks whether there is an OC to be established in front of the current running line; if there is, then Send a communication establishment request to the OC; after receiving the communication establishment request, the OC checks the status of the current jurisdiction area; if the OC determines that the status of the current jurisdiction area is a normal communication status, it sends ID information including all communication trains within the jurisdiction of the OC to the train response; VOBC identifies the ID information of the adjacent preceding vehicle of the current train according to the ID information of all communication trains; VOBC establishes communication with the adjacent preceding vehicle according to the ID information of the adjacent preceding vehicle, and obtains the adjacent preceding vehicle According to the running status information of the adjacent vehicle in front and the running status information of the current train, the MA in the jurisdiction of the OC is obtained to track the running of the preceding vehicle. The method of the invention can greatly improve the efficiency of rail transit.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train tracking operation method without secondary rail detection equipment and a CBTC system. Background technique [0002] The architecture of the traditional CBTC (Communication Based Train Control System, communication-based automatic train control system) is shown in the attached figure 1 , the CBTC mainly includes: equipment located in the control center for automatic train monitoring (such as the control center), a wireless transmission network (such as a distributed control system, Distributed Control System, referred to as DCS), on-board equipment, and ground equipment. Among them, the ground equipment includes: ZC (Zone Controller, area controller), interlocking system CI, trackside signal machine, trackside axle counter, trackside transponder, etc. [0003] The traditional CBTC system is mainly based on ground control. The train actively accepts the control of t...

Problems solved by technology

However, in the process of train sorting, it relies on secondary track detection equipment. A large number of secondary track detection equipment not only increases the logical complexity of the entire system, such as the need to convert the relationship between the position of the train and the axle recording section, It makes the installation and maintenance of the whole system difficult and increases the system cost
