Embodiment Construction

[0021] In order to make the technical solutions and advantages of the embodiments of the present application more clear, the exemplary embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and Not all embodiments are exhaustive. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0022] When the train is in AM (autonomous driving) mode, the ATO of VOBC determines the target speed of the train according to the current position of the train, target parking point, movement authorization, line speed limit, train control parameters, etc.; ATO according to the current train speed, through the PID A controller (Proportion Integration Differentiation controller, proportional-integral-derivative) or other ...

Abstract

The embodiments of the present application provide a control method, ATO, VOBC, and train for precise train parking, and relate to the operation control technology of urban rail transit trains, which are used to overcome the poor parking accuracy caused by the fact that train parking is easily over- or under-standard in the related art The problem. The method includes: when the train is in a precise stop stage, the automatic train operation control subsystem ATO obtains the current train speed and the corresponding target speed; when it is determined that the train speed is less than the corresponding target speed, the ATO The output braking rate is determined according to the target braking rate in the precise stop phase; the output braking rate is used to trigger the braking system of the train to respond according to the output braking rate; wherein the output braking rate is less than the target braking rate.

Description

technical field [0001] The present application relates to the operation control technology of urban rail transit trains, and in particular, to a control method for precise stopping of trains, ATO, VOBC and trains. Background technique [0002] VOBC (Vehicle on-board Controller) is an on-board device installed in urban rail transit trains (hereinafter referred to as trains), and is used to implement vehicle-ground wireless communication. VOBC includes an ATO (AutomaticTrainOperation, automatic train driving) subsystem (hereinafter the ATO subsystem is referred to as ATO), and the ATO is used to control the train for automatic driving. [0003] In the related art, when the train is in the AM (autonomous driving) mode, the ATO determines the target speed of the train according to information such as the current position of the train, the target parking point, the movement authorization, and the line speed limit; the ATO determines the target speed of the train according to the ...
