Automatic turn-back method of CBTC train with two ends loaded with vehicle-mounted devices

Abstract

The invention discloses an automatic turn-back method of a CBTC train with two ends loaded with vehicle-mounted devices. The method includes the following steps that S1, the train enters a turn-back region, and a master control end is in wireless communication connection with a non-master control end; S2, final-terminal stopping is conducted after the train enters the turn-back region, and a region controller confirms that a wireless communication link among the region controller, the master control end and the non-master control end is normal; S3, end exchange is conducted on the master control end and the non-master control end; S4, a new mater control end generated after end exchange is conducted is authorized by the region controller to enter a target platform, and the whole turn-back process is finished. According to the automatic turn-back method, the region controller serves as the third party to confirm the information link of the master control end and the non-master control end so as to guarantee normal operation of the wireless link among the master control end, the non-master control end and the region controller, end exchange and mobile authorization control over the master control end and non-master control end is achieved, unmanned automatic turning back of the train is achieved, and the aims of automatic turning back and communication between vehicle-mounted devices at the two ends of an existing CBTC train are achieved under the situation that no fixed communication line exists for mutual communication.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to an automatic return method for a CBTC train loaded with vehicle-mounted equipment at both ends. Background technique [0002] With the rapid development of wireless communication technology, the reliability and availability of wireless communication have been greatly improved. CBTC system (Communication Based Train Control System, communication-based train operation control system) has become an emerging operation control system in urban rail transit. The CBTC system is a new generation of signaling system that breaks through the boundary of fixed blockage and is completely separated from the track circuit. It provides more precise train control, continuous train safety separation and overspeed protection through high-precision train positioning technology and uninterrupted train-to-ground communication , so that the train can achieve safe operation in a shorter runn...

Problems solved by technology

[0004] Both manual reentry and automatic reentry in the prior art require the participation of the driver, and when the switches and physical communication lines used in the manual reentry communication link fail during operation, it will result in the inability to communicate between the on-board controllers at both ends. automatic reentry
