Embodiment Construction

[0079] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0080] As shown in Figure 1, the software for the analysis of the reentry capability includes five modules: line data, train model, signal system constraints, reentry capability analysis, and printout of analysis results; three data preparation modules are line data, train model, and signal system constraints After the data is prepared, input the reentry capability analysis module, calculate through computer simulation, and finally print out the analysis results. Among them, in the turn-back capacity analysis module, the synthetic speed limit curve of the line is calculated in the turn-back line expansion diagram, so as to realize the simulation operation of the train. It is mainly used to calculate the train running time ti / Ti between the key points in the analysis module, and the key point The position is involved in the calculation...

Abstract

The invention is a method for analyzing the turning-back capacity of rail traffic lines, adopting simplified line layout and simplified train running time-distance sketch map to analyze constraints between trains: by setting a margin for each constraint, not only able to obtain turning-back interval but also able to obtain the margin of each constraint; listing the constraints according to the stay time in station and the stay time in turning-back region, thus not only able to obtain the current adopted time margins of the stay time in station and the stay time in turning-back region; the running time ti / Ti of train at each key point is extracted by a method of generating line synthesis speed limiting curve on the development diagram of turning-back lines, generating V-S and T-S curves by computer simulation. And the analyzing method is simple and visual, not only improving analyzing completeness and accuracy but also largely reducing workload of analyzers by computer simulation.

Description

Technical field: [0001] The invention relates to an analysis method for the turn-back capability of urban rail transit lines, more specifically, it uses computer simulation calculations and simplified layout diagrams to complete the analysis calculations, and belongs to the technical field of analysis methods. Background technique: [0002] The measure of line turnback capability is the turnback interval. The turn-back interval refers to the minimum allowable interval between the start of the turn-back operation of the first train and the start of the turn-back operation of the second train. [0003] Theoretical research and actual field operation experience show that the line passing capacity of urban rail transit is mostly limited by the turn-back capacity (ie, turn-back interval) of the terminal station or long-short intersection station, and the turn-back capacity is often the bottleneck of the line passing capacity of urban rail transit. Therefore, the analysis of turn...
