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.

Embodiment Construction

[0022] The existing positioning technology is basically based on a wayside beacon + a vehicle-mounted beacon reading unit, and the train position is known through the position of the beacon. However, the position of the train will be lost due to errors in beacon reading, missing reading, and missing turnout tables.

[0023] The invention is based on the characteristics of trackside ATP continuous tracking of trains, after the train position is lost, the unmanned train positioning and automatic recovery are quickly completed, the interval stopping time is reduced, and the impact on passengers is reduced.

[0024] Such as figure 1 As shown, an automatic recovery method for unmanned train positioning based on trackside ATP monitoring. During the driving of the unmanned train, the on-board ATP continuously locates through the positioning equipment and continuously reports the position to the trackside ATP. When the positioning equipment fails, When the on-board ATP is out of position,...

Abstract

The invention discloses an unmanned train positioning automatic recovery method. When a train-mounted ATP loses the position, the following steps are executed, wherein the following steps include thatfirstly, the train-mounted ATP conducts emergency braking immediately to stop a train, and a trackside ATP estimates the maximum and minimum possible positions of the train according to the final train positioning and the possible movement characteristic of the train; secondly, after the train is stopped, the train-mounted ATP applies positioning initialization authorization to the trackside ATP,and the trackside ATP locks the distance enough for the train to be positioned according to the application of the train-mounted ATP and sends the positioning initialization authorization to the train-mounted ATP after distance locking operation is completed; thirdly, the train-mounted ATP controls the train to move forwards at the specific limited speed according to the authorization, and the train-mounted ATP completes positioning within the authorized distance; and fourthly, after the train-mounted ATP completes positioning, the train is controlled to stop, after the trackside ATP obtainsstop information of the train-mounted ATP, locking is canceled, recovery is conducted, and movement authorization is calculated for the trackside ATP according to a movement blocking principle. By theadoption of the method, a recovery process can be conducted immediately after an equipment positioning fault happens, the stop time of the train in a section is short, and influence on passengers issmall.

Description

Technical field [0001] The present invention relates to the technical field of rail transit, in particular to an unmanned train control method. 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, while the secondary train detection can only be used to realize the road-level protection of the interlocking system. When the on-board positioning equipment fails, the train is driven manually. [0003] Unmanned driving is a fully automatic unmanned driving system, where there is no driver on the train. When a failure causes the train to lose its position and the positioning equipment fails to be relocated, the rescue train or the dispatched driver can only be used to get on the train from the section. The rescue time is long and the operation of the system is also greatly affected. Summary of the invention [0004] The technical problem to be solved by the present invention i...
