Problems solved by technology

[0005] 1. It does not conform to the actual situation. For example, when the current train and the preceding train have a large distance between trains, it will cause a backlog of passengers at the station. In this case, it is obviously impractical to reduce the stop time. If you insist on reducing the stop time, not only Passengers are very dissatisfied, and the backlog of passengers will cause delays to the next train, that is, delay spread
[0006] 2. The impact of the front and rear cars is not considered. During the actual operation of the train, the front and rear cars are interrelated
The existing technical scheme only takes the bicycle as the adjustment object, without overall consideration

Embodiment 1

[0088] refer to image 3 As shown, assuming that there are 3 trains (1, 2, 3) running on a certain line, there are 4 stations in total (A, B, C, and D stations respectively), the train route is circular and the train runs counterclockwise, and train 1 is located at Between stations C and D, train 2 is located between stations D and C, train 3 is located between stations B and A, and the four stations are evenly arranged. When an accident or failure occurs, the interval between trains is 2 minutes ( The initial travel interval h between train 1 and train 2 2,0 ), 3min (the initial interval time h between train 2 and train 3 3,0 ) and 10min (the initial interval between train 3 and train 1 h 1,0 ).

[0089] Set target driving distance h 0 The planned running time of each section is 2 minutes. The planned running time of the section refers to the planned running time of the train between two adjacent stations, and the running buffer time of the interval between stations. ...

Embodiment 2

[0114] refer to Figure 4 As shown in , assuming a sudden failure of a certain train, the driver resumes normal operation after troubleshooting and solving the failure. Figure 4 .

[0115] The circle line indicates the line, the boxes indicate the stations (A, B, C, D, E, F, G), and the red boxes indicate the trains (01, 02...09), where the train 01 is located between A station and B station, and the train 02 is located at Between station C and station D, and so on, as shown in the figure, the specific location of each train will not be repeated.

[0116] Assumed target distance between vehicles h 0 5 minutes, the planned running time of each section is 2 minutes, and the running buffer time of each section δ i 1min, that is, after adjustment, the maximum interval operation time is 3min, the minimum interval operation time is 1min, the planned stop time of each station is 40s, and the stop buffer time of each station ε i is 20s, that is, after adjustment, the maxim...

Abstract

The invention discloses a train interval adjustment method and system, which includes a train interval calculation module, a train interval analysis module, an adjustment module and an arbitration module; the train interval calculation module includes a train time information acquisition unit and an initial interval calculation unit; the train interval analysis module The module includes an interval acquisition unit and an analysis and adjustment unit; an adjustment module is used to adjust the interval running time and stop time of each train; an arbitration module is used to judge whether the train interval meets the target value. At the same time, the above system is used to propose an adjustment method. Through the above adjustment method, each train can be adjusted efficiently to make the arrival and departure intervals balanced, and the normal operation of the system can be restored as soon as possible. Ensure the level of passenger service.

Description

technical field [0001] The invention relates to the technical field of urban rail transit operation, in particular to a train interval adjustment system and an adjustment method thereof. Background technique [0002] When the urban rail transit system is subject to large-scale delays caused by unexpected accidents or failures or some trains are out of service, it is impossible for the trains to resume operation according to the planned operation diagram. At this time, the adjustment goal is to restore the normal operation of the entire transportation system, maintain high-density traffic and balance the interval between train arrivals and departures to quickly transport passengers. At this stage, when encountering such a situation, the train dispatcher mainly selects the train operation adjustment strategy based on experience. The dispatcher's work intensity is high, and the efficiency and reliability of train operation adjustment are low. Unreasonable train operation adjus...
