摘要: 针对目前联锁控制数据编制过程中存在的效率低下、数据准确性依赖设计人员技术水平等问题，提出了一种铁路计算机联锁控制数据自动生成方法。以文本格式的站场基础数据作为输入，定义各类数据模型，制定空间邻接与逻辑邻接规则，以建立数据模型之间的拓扑关系，构建铁路站场拓扑模型；采用基于最短欧氏距离的进路搜索算法获取站内所有进路；自动输出联锁控制数据。采用上述方法开发实际软件，展示联锁控制数据的自动生成过程。结果表明，所提方法可快速准确地生成联锁控制数据，提高编制联锁控制数据的自动化程度与效率，提高铁路计算机联锁控制系统的通用性和自适应性。Abstract: Aiming at the problems of low efficiency and data accuracy depending on the technical level of designers in the process of compiling interlocking control data, this paper proposed an automatic generation method of railway computer-based interlocking control data. Based on the basic data of railway stations in text format as input, the paper defined various data models, formulated spatial adjacency and logical adjacency rules, established the topological relationship between data models, and constructed the topological model of railway station yard; used the route search algorithm based on the shortest Euclidean distance to obtain all routes in the station; and automatically outputed interlocking control data, used the above method to develop practical software to show the automatic generation process of interlocking control data. The results show that the proposed method can generate interlocking control data quickly and accurately, improve the automation and efficiency of compiling interlocking control data, and help to improve the universality and adaptability of railway computer-based interlocking control system.
