Train stop control method, device and train

Abstract

The invention provides a train parking control method and device, and a train. The train parking control method comprises the steps that a skip train-control request sent by a train-mounted control system is received; a control mode is adjusted to be a skip module according to a skip instruction, and a skip distance is divided according to a preset dividing strategy to obtain a traction distance;a traction system of the train is controlled to pull the train at the preset traction level, and meanwhile, a braking system of the train is controlled to brake the train at the first preset braking level; and when it is detected that the traveling distance of the train is equal to the traction distance, the traction level of the traction system returns to zero, the braking system is controlled tobrake the train at the second preset braking level, and thus the train decelerates till the train stops stably, wherein the traveling distance of the train is the distance from the current position of the train to the preset position, and the preset position is the position corresponding to the train when the train receives the skip train-control request. Therefore, accurate parking is achieved,and control accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a train parking control method, device and train. Background technique [0002] With the development of urban rail transit, it is particularly important for the operation safety reliability and service quality of rail transit related equipment such as subways, urban rails, and cloud rails. [0003] At present, when the urban rail vehicle is in the automatic mode, when the urban rail vehicle is approaching the station, the automatic train operation system (Automatic Train Operation, referred to as ATO) in the vehicle on-board controller (Vehicle on-board Controller, referred to as VOBC) is generally used. Complete the positioning and speed measurement of the train, and complete the calculation of the control command for the train according to the above positioning and speed measurement information. After the control command is obtained, the train operation is controlled...

AI Technical Summary

Problems solved by technology

[0004] In the process of train parking, the entire train control link involves many devices and the control process is complex, which makes the control process unstable and delayed, resulting in a low degree of precise control and poor parking accuracy when the train is controlled by ATO.
