Problems solved by technology

[0004] At present, in the prior art, there has been a certain amount of theoretical accumulation on the use of section crossings to adjust train operation, but most of them have not analyzed the train adjustment strategies in different situations in detail, and cannot calculate the train in various operating paths in detail. The total delay time of trains, so it is impossible to obtain a locally optimal scheduling plan, let alone effectively prevent the spread of train delays

Embodiment 1

[0039]The embodiment of the present invention provides a train operation adjustment method using the reverse track. The method is applicable to the situation where a train running on a high-speed railway section encounters an emergency and decelerates urgently. This strategy is used to arrange the deceleration train The surrounding vehicles use the section crossing line to adjust their own driving path, so that the total delay time of the train is minimized.

[0040] In order to facilitate description and understanding, some symbols and variables are defined, as shown in Table 1.

[0041] Table 1: Define symbols and variables

[0042]

[0043] Let the moment when the uplink train i encounters an emergency in the BC section be t. make and equal to duration d i,B -t, is the estimated time required to arrive at crossing line B when train i does not conflict with other train departures; When train i conflicts with other trains, it takes time to reach crossing line B. ...

Embodiment 2

[0090] The invention provides an integrated strategy for high-speed railway dispatching control, establishes a mathematical model (that is, the total delay time of trains under different operating paths), selects a locally optimal high-speed train dispatching strategy, reduces the total delay time of trains, and suppresses the delay time of trains. spread of delays.

[0091] In the method of the present invention, according to the Beijing-Tianjin intercity line train timetable, it is randomly assumed that some trains encounter unexpected situations in the section and slow down, and reasonably formulate the time of delay and the time for slowing down due to unexpected events. The section and the moment when the emergency is encountered, the train number and the name of the station are given.

[0092] Reasonable assumption parameters: (1) The departure time of the first train is time 0; (2) The minimum time interval between the two trains running in the interval at normal speed ...

Abstract

The invention provides a method for adjusting train operation using a reverse track. The method includes: train i and train i+1 are two uplink trains running on the uplink track, train i is the front vehicle, train i+1 is the rear vehicle, train k is the downlink train running on the downtrack, and the uplink There is a crossover line between the track and the down track. At time t, train i encounters an unexpected situation on the BC section and decelerates; calculate the first train i+1 when train i+1 continues to track the operation of train i on the up track. Total delay time, calculate the second total delay time of the train when train i+1 utilizes the crossover and the down track to surpass train i; compare the first total delay time of the train with the second total delay time of the train, and determine according to the comparison result The running route of train i+1. The invention arranges the vehicles around the decelerating train to adjust its own driving path by using the interval crossing line, so that the total delay time of the train is minimized.

Description

technical field [0001] The invention relates to the technical field of train dispatching, in particular to a method for adjusting train operation using reverse tracks. Background technique [0002] In recent years, high-speed railways have developed rapidly in China and become the lifeline of the national economy. Fast running speed and less delay time are the advantages of high-speed railways, and they are also the basic requirements of my country's railway system for high-speed railways. However, if a high-speed train in the section slows down due to an unexpected situation, the delay of this train is likely to spread to the following trains, causing a large area of ​​trains to be delayed. [0003] In order to deal with the emergency deceleration of a certain high-speed train in an interval, reduce the total delay time of the train in such cases and reduce the spread of train delays, it can be considered to use the interval crossing line to adjust the running path of the ...
