Description

Technical Field

[0001] This invention relates to the field of railway station layout design, and specifically to a method for the coordinated design of railway station turnouts and tracks. Background Technology

[0002] In railway station layout design, turnouts and tracks, as core basic design units, serve as the skeletal elements for locating and referencing other facilities such as station drainage, platforms, signaling, and overhead contact lines. Their design rationality directly determines the scientific nature of the overall station layout and operational efficiency. However, traditional design models treat turnouts within the throat area as unrelated devices, lacking coordination between turnouts and between turnouts and tracks. This design model has the following significant drawbacks:

[0003] When modifying a single turnout, due to rigid geometric constraints such as track length and the distance between the curve head and the turnout heel, a large-scale manual check and adjustment of turnouts and tracks is required, resulting in low efficiency.

[0004] When modifying multiple turnouts, they must be adjusted and checked repeatedly in a cycle to meet the design specifications.

[0005] When faced with optimization needs such as adjusting the angle of the train yard or adjusting the parallel route in the throat area, all tracks and switches need to be manually corrected, which may even lead to the redesign of the entire throat area and even the station yard plan. The operation process is cumbersome and prone to conflict, which may lead to repeated adjustments in the subsequent design stage, and the cost of manual intervention is high. Summary of the Invention

[0006] The purpose of this invention is to provide a railway station turnout and track linkage design method based on a three-layer model of "turnout action chain - turnout action tree - turnout action forest" to solve the problems of insufficient linkage, low adjustment efficiency and high cost of manual intervention in the traditional design mode.

[0115] Figure 4This invention demonstrates the effect of a coordinated translation of the left throat area of ​​the station in an embodiment of the present invention. The solid line represents the design result of the left throat area of ​​the station before adjustment, and the arrow direction indicates the adjustment direction. The dashed and dotted lines represent the dynamic preview results generated in real time through coordinated design under a specific movement matrix. The dashed lines represent straight track segments in the dynamic preview results, and the dotted lines represent curved track connection segments in the dynamic preview results.

[0116] Figure 5 This invention demonstrates the effect of a linked rotation of the station yard connecting lines in an embodiment of the invention. Solid lines represent the partial design results of the station yard before adjustment, and the arrows indicate the adjustment direction. Dashed lines and dotted lines represent the dynamic preview results generated in real time through linked design under a specific rotation matrix. Dashed lines represent straight track segments in the dynamic preview results, and dotted lines represent curved track connecting segments in the dynamic preview results.

[0117] Traditional design methods treat turnouts and tracks within a station as independent entities. When modifications are made to a local plan, geometric constraints such as turnout track length and the distance from the curve head to the turnout heel limit necessitate extensive manual adjustments and checks of related turnouts and tracks, sometimes even requiring manual redesign of the throat area or the entire station layout. During the optimization process, designers often need multiple rounds of adjustments and repeated checks, resulting in cumbersome procedures, a high risk of geometric conflicts, low design efficiency, and a high error rate.

[0118] After adopting the linkage design method of the present invention, such as Figure 4 , Figure 5 As shown, the algorithm uses a three-layer model of "turnout action chain - turnout action tree - turnout action forest" to automatically identify all related turnouts and tracks, dynamically calculate and generate a preview of the scheme in real time. Designers can quickly and conveniently complete the adjustment of station schemes, significantly improving design efficiency, especially in the scenario of complex scheme adjustment for large stations, where design efficiency can be improved by more than 5 times.
