Method for quickly positioning dormant train based on storage memory

Abstract

The invention discloses a method for quickly positioning a dormant train based on storage memory. The method comprises the following steps of firstly, enabling a train to enter a dormancy waking area, memorizing the train position before dormancy by train-mounted ATP (automatic train protection) or trackside ATP, and enabling the train to enter the dormant state; then, after the train is waked up from the dormant state, enabling a position detection device arranged in the train dormancy waking area to obtain the effective positioning information of the train, and combining the effective positioning information of the train and the memorized position information of the train before dormancy to check the train position, and judging whether the train is allowed to enter a positioning state or not; finally, after the train enters the positioning state, enabling the train-mounted ATP to report the position information to the trackside ATP, and converting the tracking mode of the train from a previous NTQB (dormant rain tracking mode) into TVB (communication train tracking mode) after the trackside ATP receives the position information. The method has the advantage that when a skipping interface is not provided between the train and a signal system, the train can also be quickly positioned.

Description

technical field [0001] The invention relates to a rail transit CBTC control technology, in particular to a fast positioning technology for a dormant train. Background technique [0002] In the rail transit CBTC control system, before the train is operated, it needs to be manually powered on, self-inspected, and then departed according to the manual driving RM mode. The train runs at a low speed in the RM mode, and enters the In the positioning initialization state, the CBTC control system allows the train to enter the driving mode with on-board ATP protection function, such as FAM / AM / CM mode, after the second positioning beacon obtains effective position information and enters the positioning state. [0003] In the prior art, manual participation is required for the power-on and self-inspection of the train, and after the self-inspection is completed, the train can only enter the positioning state after driving the train at a very low speed and passing the two positioning be...

Problems solved by technology

[0003] In the existing technology, manual participation is required for the power-on and self-inspection of the train, and after the self-inspection is completed, the train can only enter the positioning state after driving the train at a very low speed and passing the two positioning beacons, and then the train is allowed to enter the equipped The driving mode of the on-board ATP protection function (including the fully automatic driving mode), from the power-on of the train to the automatic driving operation, requires the driver to participate, and the whole process takes a long time and the operation efficiency is low
