Train tracing running method implemented without secondary railway testing equipment and communication based train control (CBTC) system

Abstract

The invention discloses a train tracing running method implemented without secondary railway testing equipment and a communication based train control (CBTC) system. The method comprises the following steps that in the train running process, a vehicle on board controller (VOBC) of a train checks whether an object controller (OC) waiting to set up communication connection exists or not in the front of a present running line; if the OC waiting to set up communication connection exists, a communication setting request is sent to the OC; the state of a present jurisdiction is checked after the OC receives the communication setting request; if the OC confirms that the present jurisdiction is in a normal communication state, responses to identification (ID) information of all communication trains in the jurisdiction of the OC are sent to the train; the VOBC can recognize the ID information of a front train adjacent to the present train according to the ID information of all the communication trains; the VOBC sets up communications with the adjacent front train according to the ID information of the adjacent front train and obtains running state information of the adjacent front train; and according to the running state information of the adjacent front train and the running state information of the present train, movement authority (MA) in the jurisdiction of the OC is obtained so as to trace running of the front train. Efficiency of railway transportation can be improved greatly by means of the train tracing running method.

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...
