Abstract Research purposes:The layout of train parking lanes is an important part realization of station automation design. This paper aims to establish a mathematical model for the automatic layout of the standard station parking lanes, and provide real-time parameterized modeling. With baseline as a reference, a scientific mathematical distribution model is established based on the spatial topological relationship between parking lanes and baseline. This mathematical model is adjusted by parameters to realize the ability of rapid space layout design for parking lanes on general standard station. The distribution model is based on the baseline of the track surface, and all calculations are based on mileage and left-right distance inference, and are loosely coupled with space, thus ensuring the synchronous support of the slope station and the curve station.
Research conclusions:(1) Based on the distribution characteristics of the parking lanes in standard station yard, a spatial distribution mathematical model for 6 sets 10 lanes including more than 120 control parameters was constructed. (2) Through the linkage deduction of multiple control parameters, the precise drive of the parking lanes distribution model is realized, which meets the needs of the station yard for rapid modeling and diversified parameter configuration. (3) The reliability and stability of this mathematical distribution model are verified by experiments and actual modeling effects, which provides an implementation method for the automatic station modeling of the 3D line selection design system, and has provided rapid modeling support for more than 50 stations in 20 engineering projects.
