Problems solved by technology

However, in practical applications, due to various reasons, the speed measurement resolution of the train cannot meet the requirements. For example, in the maglev line, due to the irregular laying distance of the sleeper, the speed measurement resolution of the train will be relatively low.
At this time, there is a certain deviation in the speed measurement resolution of the train, which cannot meet the requirements, and the solution provided by the existing technology will not be able to realize the precise parking of the train.

Embodiment Construction

[0024] The precise train parking scheme provided by the prior art has high requirements on the speed measurement resolution of the train, and is not suitable for the case where the speed measurement resolution is low. The train parking control method and system provided by the present invention utilize positioning synchronous points and one-time braking to realize accurate parking of trains in stations under various speed measurement resolutions.

[0025] A kind of train parking control method is described at first, and this method comprises:

[0026] The speed at which the train enters the station is adjusted to the station entrance speed; the station entrance speed is obtained by the train automatic protection curve and the speed limit in the station;

[0027] When the train enters the station, the current distance between the train and the operating parking point is determined according to the pulse signal sent by the preset positioning synchronization point on the track re...

Abstract

The invention discloses a train stopping control method and system. The method comprises the following steps: adjusting the speed of a train to arrive at a station to a station entrance speed which is obtained by an automatic train protection curve and an in-station limit speed; when the train arrives at the station, determining the current distance between the train and an operation parking spot according to a received pulse signal sent by positioning synchronization points preset on a track; calculating a recommending speed corresponding to the current distance through a train control algorithm according to the current distance between the train and the operation parking spot, and adjusting the current speed of the train; and exerting a recommended brake gear on the train to reduce the speed and stop the train when the train passes through the last positioning locating synchronization point. According to the technical scheme provided by the invention, the influence caused by low speed measurement resolution is reduced; and the train can accurately stop in the station under various speed measurement resolutions.

Description

technical field [0001] The invention relates to the technical field of train automatic control, in particular to a train parking control method and system. Background technique [0002] With the emergence of the ATC (Automatic Train Control, automatic train control) system, the train has realized automatic protection, automatic driving, and automatic monitoring. Among them, the ATO (Automatic Train Operation, automatic train driving) system is an important subsystem of the ATC system, which can complete the control function of the train door switch and automatic speed adjustment (including traction, cruising, coasting, braking and parking control), to achieve Automatic control of main line, return line, etc. For an ATC system, whether the precise parking of the train in the station can be realized directly affects the reliability of the whole system. [0003] In the prior art, several typical schemes such as stage speed control, fuzzy control algorithm or PID (Proportion I...
