cbtc unmanned vehicle vehicle control system with intelligent obstacle detection and early warning function

Abstract

The invention discloses a CBTC unmanned vehicle-mounted control system with intelligent obstacle detection and early warning functions, including a vehicle-mounted ATP for train control and an obstacle detection system for track obstacle detection. The obstacle detection system includes a non-contact The long-distance obstacle detection subsystem and the contact obstacle detection subsystem, the non-contact long-distance obstacle detection subsystem will output warning information to the on-board ATP in advance when detecting obstacles on the track ahead of the train. Control the speed limit of the train. The contact obstacle detection subsystem outputs information to the vehicle-mounted ATP after detecting that the train has collided with an obstacle. The vehicle-mounted ATP immediately implements emergency braking and sends an information alarm to the ATS. On-board ATP cannot authorize train departures when cleared. The present invention can comprehensively realize the unmanned operation control of the train according to the line information, the operation plan and the obstacles in the track and the train operation limit during the train operation process.

Description

technical field [0001] The invention relates to rail transit technology, in particular to a CBTC unmanned vehicle-mounted control system. Background technique [0002] The existing CBTC unmanned on-board control system provides safety protection functions such as train running interval control, overspeed protection, train door and platform door supervision in the ATP system, and adopts continuous speed-distance curve control mode for train control, which conforms to the fail-safe principle On the basis of the ATO system, the ATO system automatically completes the fixed-point parking at the station, scheduled departure, inter-station driving, door control and corresponding dispatching arrangements according to the line conditions, operation plan and other information, so as to realize the automatic operation of the unmanned train on the established line. [0003] During the driving process of the unmanned train, it is not only limited by the control of line conditions and ope...

AI Technical Summary

Problems solved by technology

[0003] During the driving process of the unmanned train, it is not only limited by the control of line conditions and operation plans, but also the train is invaded by obstacles in the track and tunnel, and the state of the train should also be processed. The current unmanned vehicle control system is sure It is impossible to predict and control train operation, which brings hidden dangers to the further popularization of unmanned train operation
