AI Technical Summary

Problems solved by technology

Especially when there is an event that the vehicle fails to run, due to a series of complex operations, including clearing passengers of the faulty vehicle, linking the rescue vehicle with the faulty car, pushing, etc., the train will usually be delayed for 5 minutes or more
Therefore, the automatic adjustment method of the operation diagram at this stage is often not applicable to the scene where the subway vehicle fails to operate.

Embodiment 1

[0033] At present, the train operation adjustment method is often only adjusted for the delay within 0-5 minutes. Moreover, the turnover of trains is also closely related to the operation of the subway. In the operation diagram, the departure interval of the train directly affects the number of trains put into operation. Whether to turn back at the terminal also directly affects the arrival and departure time of each station. However, the existing methods for automatic adjustment of subway train diagrams often do not use operation adjustment methods such as additional driving of spare trains and halfway turnarounds, which cannot make full use of vehicle and line resources. At the same time, the existing automatic adjustment method of the subway train diagram usually does not consider the turnover of the vehicle bottom. Based on this, this embodiment provides an automatic adjustment method for subway train rescue, such as figure 1 shown, including:

Embodiment 2

[0213] Taking Fangshan Line as an example, the planned operation diagram before adjustment is as follows Figure 5 shown. According to the method of embodiment 1 of the present invention, the automatic adjustment example of subway train rescue under the condition that the vehicle fails to run is as follows: Image 6 , 7 shown. The basic parameter configuration is shown in Table 1, where the indexes of trains and stations are calculated from 0:

The ordinate of the operation diagram is the station, and there are 24 uplink and downlink stations, among which the depot is connected to the station with the index 23, and the abscissa indicates the time, and the departure interval of the uplink and downlink trains is 3 minutes. The solid line in the figure repre...

Abstract

The invention relates to an automatic adjustment method and system for subway train rescue. The method comprises the steps of acquiring fault information and train number information of a train number to be adjusted, and determining the time for arriving at each station after a fault train and a rescue train are coupled according to the fault information; taking a train bottom turnover and train midway turn-back constraint model, a train minimum stop time constraint model, a train running time constraint model, a train departure interval constraint model and a train stop time constraint model as constraint conditions; taking the minimum sum of the total number of stations where each train number to be adjusted stops operating and the offset as a target to construct a train running chart automatic adjustment model; inputting the train number information into an automatic adjustment model to obtain actual operation data of each train number to be adjusted; and constructing an actual running chart according to the time of arriving at each station after coupling and the actual running data. Underbody resources and line resources are fully utilized, the subway train rescue adjustment efficiency is improved, and after rescue is finished, the normal operation order can be rapidly restored.

Description

technical field [0001] The invention relates to the technical field of subway train operation control, in particular to an automatic adjustment method and system for subway train rescue under the condition that the vehicle fails to run. Background technique [0002] The development of urban rail transit system (hereinafter referred to as subway) is changing with each passing day, and the road network structure is becoming more and more complex. The rapid development of the subway has brought great convenience to the travel of urban residents. In the case of the ever-increasing scale of subway development, once failures and emergency conditions occur, it is easy to cause adverse consequences such as train delays and outages, and even cause interruption of operations, seriously affecting the quality of passenger service. [0003] Therefore, the adjustment technology of the train diagram plays an important role as a key technology in the operation and management of the urban s...
