Problems solved by technology

[0005] The disadvantages of the existing technology are: the following train must wait for the preceding train to stop on the arrival and departure line before unlocking the route and starting to handle the route, resulting in long intervals between train arrivals, low efficiency of receiving trains, and poor utilization of equipment such as turnouts. Low

Embodiment

[0049] Taking the high-speed field of Shanghai Hongqiao Station as an example, simulation experiments are carried out on all the combination schemes of arrival and departure lines (except the main line), and the influence of different combination schemes of arrival and departure lines on the minimum arrival and tracking interval of trains is studied.

[0050] Basic parameters of the experiment

[0051] The simulation object is the Shanghai-Nanjing section of the Beijing-Shanghai Line. The starting point is 20km in the upward direction of the high-speed field of Shanghai Hongqiao Station, and the end point is the high-speed field of Shanghai Hongqiao Station. The train running direction is downward. The CRH380BL EMU is selected as the simulation subject for tracking operation, and the 16-section marshalling method is adopted, and the L 列 = 400m.

[0052] There are 10 platforms and 19 lines in the Shanghai Hongqiao Station Expressway. The station type diagram is as follows im...

Abstract

The invention discloses a train arrival tracking interval time compression method based on arrival and departure line application, and the method comprises the steps: obtaining a calculation method ofarrival tracking interval time under a segmented unlocking condition through the analysis of a train tracking process under the segmented unlocking condition, and compressing the train arrival tracking interval time based on an arrival and departure line application scheme optimization method. The method has the advantages that the method is simple; on the basis of an existing train receiving route segmented unlocking technology, through a reasonable arrival and departure line application optimization method, the time from the clearing of associated turnouts to the clearing of throats of a preceding train in the train arrival tracking interval time is shortened, the compression effect on the train arrival tracking interval time of domestic large railway passenger stations is good, and theapplication range is wide.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train arrival tracking interval time compression method based on an arrival and departure line operation scheme. Background technique [0002] According to the analysis and specific calculation of my country's high-speed railway train tracking interval time, the departure tracking interval time (I 发 ) at about 170s, interval tracking interval (I 追 ) is around 140s, while the train arrival tracking interval at large stations (I 到 ) reached above 230s. Therefore, the train tracking interval (I) is mainly affected by the large station I 到 limits. [0003] Therefore, compressing the arrival and tracking interval of high-speed railway trains can significantly improve the passing capacity of the line, thereby alleviating the problem of the tight capacity of the busy trunk line. [0004] At present, the existing technology is to unlock the car-receiving route once: if a rout...
