Driverless train positioning failure rescue method

Abstract

The invention discloses a driverless train positioning failure rescue method. When positioning equipment breaks down and a positioning failure happens to a train-mounted ATP, the following steps are executed that firstly, emergency braking parking is immediately performed by the train-mounted ATP, and the fault information of the positioning equipment is reported to a trackside ATP; secondly, after the trackside ATP acquires the fault information, reported by the train-mounted ATP, of the positioning equipment, a train is locked from a positioning failure position to the area of a station / evacuation platform, and after other trains all drive out of a locking area, real-time movement authority is sent to the train-mounted ATP, wherein the real-time movement authority includes command validtime and allowable running speed; thirdly, after the train-mounted ATP receives the real-time movement authority, the train is controlled to move according to the authority; fourthly, when the trackside ATP obtains the information that the train drives into the station / evacuation platform through a secondary train detection device, sending of the movement authority is stopped. By means of the method, the recovery process can be immediately started after positioning faults of the equipment occur, the time that the train is parked in an interval is short, and influences on passengers are small.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a control method for an unmanned train. Background technique [0002] The safety protection of the fully automatic unmanned driving system of urban rail transit is based on the on-board positioning system, and the secondary train detection can only be used to realize the route-level protection of the interlocking system. When the positioning equipment fails, the train will be driven manually. [0003] Unmanned driving is especially a fully automatic unattended unmanned driving system, and there is no driver on the train. When a fault causes the train to lose its position and the faulty positioning equipment cannot be relocated, the only way to rescue the train or send the driver to get on the train from the section is the only way. The rescue takes a long time and has a great impact on the operation of the system. Contents of the invention [0004] The technical problem t...

Problems solved by technology

When a fault causes the train to lose its position and the positioning equipment fails to relocate, the only way is to use the rescue train or send the driver to board the train from the section. The rescue time is long and has a great impact on the operation of the system.
