A control method and system for fine-tuning alignment operation of incoming trains

Abstract

The invention provides a control method and system for fine-tuning alignment operation of an incoming train. After controlling the train to enter the fine-tuning alignment mode, the method periodically collects train information, controls the train to perform fine-tuning alignment operation according to the standard fine-tuning distance, and When the fine-tuning alignment running distance exceeds the protection distance, control the train to perform emergency braking, and when the fine-tuning alignment running speed exceeds the protection speed, control the train to perform emergency braking, and at the same time control the number of fine-tuning when the train is fine-tuning in the same direction. The system includes a fine-tuning alignment mode entry module, a train information collection module, a fine-tuning alignment operation module and a fine-tuning alignment mode cut-out module. The present invention realizes the control and protection of the fine-tuning alignment of the train, prevents the phenomenon of not reaching the calibrated parking point or passing the calibrated parking point that may occur again during the fine-tuning alignment, and ensures that the train can fine-tune the alignment smoothly during the fine-tuning alignment. The correct and reliable fine-tuning alignment of incoming trains is realized.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a control method and system for fine-tuning alignment operation of incoming trains. Background technique [0002] There is a phenomenon that the train cannot stop accurately when it enters the station. When the train is driven by someone, the driver can slide forward or retreat to make the train stop accurately. The fully automatic driving train also has the phenomenon of inaccurate parking when it enters the station. In response to this phenomenon, the train fine-tuning alignment technology has been added to the unmanned driving technology. [0003] The train fine-tuning alignment technology means that when the train stops inaccurately, the train switches to the fine-tuning alignment mode, and the vehicle controls the train to complete the fine-tuning alignment adjustment and alignment according to the fine-tuning alignment instructions and direction instructions.

Problems solved by technology

[0004] Because the train is affected by the passenger flow, the load cannot be determined, and the friction factor of the ground is affected by the weather. As a result, when the train is fine-tuning the alignment, the fine-tuning alignment distance is too close, resulting in multiple fine-tuning alignments, or the fine-tuning alignment distance is too large. Another phenomenon of under-bid or over-bid, at this time, manual rescue is needed to realize the parking according to the mark, which deviates from the original intention of fully automatic driving

[0005] In addition, excessive acceleration when the train is fine-tuning alignment can easily cause passengers to fall and be injured, thereby reducing the comfort of the train; these will reduce passengers' trust in fully automatic driving technology, and will also cause negative effects on the use and promotion of fully automatic driving technology. influences
