[0005] 1. The problem of passenger backlog at the station is not considered. For example, when the distance between the current train and the train ahead is large, it will cause a backlog of passengers at the station. In this case, it is obviously impractical to reduce the stop time. 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
[0086] 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 D and C, train 2 is located between stations C and D, and train 3 is located between stations A and B, and the four stations are evenly arranged. When an accident or failure occurs, the driving interval 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 ).
[0087] 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. δ ...
Embodiment 2
[0112] 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 .
[0113] The ring line represents the line, station codes (A, B, C, D, E, F, G), train numbers (01, 02...09), where train 01 is located between stations A and B, and train 02 is located between stations C and Between stations D, and so on, as shown in the figure, the specific location of each train will not be repeated here.
[0114]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, the maximum stop time of each station after adjustment is 60s, and the min...

Abstract
The invention discloses a train interval adjustment method and system. The train interval adjustment system comprises a driving interval calculation module, a driving interval analysis module, an adjustment module and an arbitration module, wherein the driving interval calculation module comprises a traintime information acquisition unit and an initial interval calculation unit; the driving interval analysis module comprises an interval acquisition unit and an analysis adjustment unit; the adjustment module is used for adjusting the interval running time and the stop time of each train; and the arbitration module is used for judging whether the driving interval of the train meets a target value or not. Meanwhile, the invention provides an adjustment method by using the system. The trainscan be efficiently adjusted through the adjustment method to enable arrival and departure intervals of the trains to be balanced, normal operation of the system is recovered as soon as possible, frontand rear trains are coordinated in the adjusting process, the residence time of passengers in stations is shortened, and the passenger service level is guaranteed.
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 railtransit 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 entire transportation system to normal operation, maintain high-density traffic and balanced train intervals to transport passengers quickly. 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 adjustments may cause large-scale delays of...
