Embodiment Construction

[0029] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0030] like figure 1 As shown, a schematic diagram of the Yizhuang Line of the Beijing Subway is provided. The subway line includes 14 stations, wherein Songjiazhuang to Yizhuang Railway Station is the upward direction, and Yizhuang Railway Station to Songjiazhuang is the downward direction. The present embodiment considers the Songjiazhuang to Yizhuang Line In the upbound direction of the railway station, the time is the peak hour from 7:00 am to 8:30 am.

[0031] like figure 2 As shown, the shaded part in the figure r...

Abstract

The invention discloses an online train automatic adjustment control method, which is characterized in that it comprises: S1: collecting train displacement and speed information; S2: judging whether the train deviates from a predetermined running curve according to the train displacement and speed information; S3: if the train deviates The established operating curve calculates and generates a new train operating curve. The steps of the calculation method include: S31: Establish a state feedback controller; S32: Establish a dynamic transfer equation for the deviation between the actual operating curve of the train and the established operating curve; S33: According to the actual operating curve of the train Establish a predictive control model based on the dynamic transfer equation of the deviation from the established operating curve and current real-time monitoring information; S34: Calculate the state feedback control gain according to the predictive control model, the transfer equation and the state feedback controller to generate an adjusted train operating curve.

Description

technical field [0001] The invention relates to the field of urban rail traffic control. More specifically, it relates to an online train automatic adjustment control method. Background technique [0002] At present, the method of train operation control system based on communication is widely used in urban rail transit. In order to deal with the interference of uncertain events (such as train signal failures and emergencies) that occur during the operation of urban subway trains, automatic train adjustment methods have become a core function of urban subway signaling systems. The method satisfies the real-time and accuracy of train automatic adjustment by designing different train automatic adjustment methods. Traditional train automatic control methods are mainly divided into two types: dynamic programming-based methods and state-feedback-based control methods. Although the dynamic programming method can comprehensively consider various constraints in train operation (s...
