Train operation method and device based on virtual grouping

Abstract

The embodiment of the invention provides a train operation method and device based on virtual grouping. The method comprises the steps: distributing train groups for a large intersection and a small intersection in a train operation mode of the large intersection and the small intersection; in the uplink interval, grouping grouped trains of the large intersection and grouped trains of the small intersection at a first turning point of the small intersection, and ungrouping at a second turning point of the small intersection; and in the downlink section, grouping the grouped trains of the largeintersection and the grouped trains of the small intersection at a second turning point of the small intersection, and ungrouping at a first turning point of the small intersection. In this way, full-area equal-interval running can be achieved, the trains are grouped or ungrouped at the small intersection turning point on the basis of the time requirement of the train operation plan, and the transport capacity matching requirements of different intersection sections are met.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of rail transit, and more specifically, relate to a virtual formation-based train operation method and device. Background technique [0002] The operation diagram is the basis of the operation organization. In the routine operation diagram preparation process, there are generally two ways of intersection: single intersection and large and small intersection. These two intersection forms have their own advantages and disadvantages. In the current environment where the number of on-line train formations is basically fixed, for a single traffic road, the traffic interval and transport capacity of each section are basically the same. Affected by the unbalanced passenger flow at the section, this traffic organization method is likely to cause waste of transport capacity ; For large and small intersections, the traffic intervals in some sections can be inconsistent, which can deal with the pr...

In the current environment where the number of on-line train formations is basically fixed, for a single traffic road, the traffic interval and transport capacity of each section are basically the same. Affected by the unbalanced passenger flow at the section, this traffic organization method is likely to cause waste of transport capacity ; For large and small intersections, the traffic intervals in some sections can be inconsistent, which can deal with the problem of unbalanced passenger flow on the section. Larger, which is not conducive to passenger travel (longer waiting time), and the cost savings are relatively limited

[0003] However, under the existing conditions, the mode of large and small intersections is adopted. Generally, large and small intersections will be operated according to a specific ratio, such as 1:1, 2:1, etc. This driving method will inevitably lead to traffic in the non-overlapping area of ​​large intersections. The interval is inconsistent with the small intersection area, and the driving interval is relatively large, which is not conducive to the improvement of passenger service level
