通用型计算机辅助设计(CAD)软件中不包括铁路车站咽喉平面设计的工具,因此需要研究专业的设计平台。本文认为解决该问题的途径是,首先基于人机交互的图型环境,输入并建立车站咽喉的结构图型,然后通过有效的计算手段识别和判定这种咽喉结构,最后通过结构计算实现车站咽喉平面设计的目标。文章认为模块法比画线法输入咽喉结构图型效率更高,也便于识别。因此,将车站咽喉的基本图形分解为6种基本图元,并对这些图元进行了恰当的描述。应用矢量对接判定条件,识别咽喉结构图型中图元的连接关系。依这种关系,应用约束推理方法和最优化的数学模型,计算满足咽喉设计条件下最优岔心位置坐标和最大平行进路数,从而实现车站咽喉平面设计优化和自动化。
Universal CAD software does not include tools for designing throat lanes at railway stations, so researching a professional design platform is required. This paper argues that the way to solve this problem is to first enter and build the structure diagram of the station throat based on human-computer interactive graphical environment, and then identify and determine the throat structure through effective calculation means, and finally realize the throat of the station through structural calculation Flat design goal. The article thinks that the module method is more efficient than the line drawing throat structure pattern, and is also easy to identify. Therefore, the basic figure of the station’s throat is decomposed into six basic primitives, and these primitives are properly described. By applying the condition of vector docking, the connection of primitives in throat structure pattern is identified. Based on this relationship, the constrained reasoning method and the optimized mathematical model are used to calculate the optimal fork position coordinates and the maximum number of parallel routes under the condition of throat design so as to optimize and automate the throat plane design of the station.
