【摘要】 随着城市化的加快,地铁由于其特有的优势成为解决城市交通压力的优秀选择,于是现在各个城市地铁建设开始加快。CBTC (Communication Based Train Control System基于通信的列车自动控制系统)由于其能够实现移动闭塞,可以大幅度的提高区间通过能力,灵活的组织双向运行和单向连续的发车,于是其代替轨道电路为基础的控制系统成为必然。随着CBTC在城市轨道交通中的应用,我们尝试开发和完善城市轨道交通CBTC仿真系统,建立城市轨道交通工程项目的计算机辅助设计平台。利用系统内嵌的列车动力学模型和列车控制模型等数学模型,为城市轨道交通项目的全过程设计提供定量分析的理论依据,便于在工程设计中通过对线路、行车组织和相关系统设备的配置进行精确的仿真计算,在确保安全的前提下实现土建和机电系统的优化配置。本文首先结合在CBTC仿真中的研发工作,首先详细的分析了图论,有向图的原理在组织线路基础数据中的应用。其中包括如何用有向图的方式来描述城市轨道交通的站场的方式；信号设备在基于有向图的站场中如何描述；线路信息在基于有向图的站场中如何描述。分析了基于有向图的线路基础数据每个子项的详细数据结构定义,存储方式,线路基础数据在CBTC仿真系统中所处位置,与其他部分的接口。分析了什么是模拟／仿真系统,模拟／仿真系统的工作原理和优势。CBTC模拟／仿真系统的系统结构,在这个系统中为什么要将基于公里标的线路基础数据与ATS(Automatic Train Supervision列车自动监控系统)显示进行映射,以及提出了两种数据映射的方法。最后详细的说明了线路基础数据管理软件的系统结构,仿真系统设计结果,以及对下一步工作的展望。更多还原

【Abstract】 With the accelerating urbanization and the unique advantage, the subway has been became the excellent choice to solve urban traffic pressure. Now all urban subway constructions begin to pick up. And with the realization of the movable block, Communication Based Train Control System (CBTC) can take place of the track circuit based control system, for its great improvement on carrying capacity of the block section, the flexible organization of two-way operation and one-way continuous departure. Also, the trend is inevitable.With the development of CBTC in the urban railway system, we try to develop and improve the urban rail transport CBTC simulation system, establishing the computer aided design platform for the project of the urban railway system. Because of the embedded train dynamics model and train control model, the system can provide the theoretical basis for the whole process design of urban rail transit projects, and can realize optimized configuration in the civil and electromechanical system through accurate calculation on the lines, traffic organization and related system in the premise of safety.Combined with the research and development of CBTC simulation, the author first analyzed the application of graph and directed graph theory in the database of the lines in detail, including how to use a directed graph to describe a urban rail transit station; how to describe the signal equipment and the route information in the station-yard based on directed graph; and finally, how to search the route. This paper also analyzed the data structure definition and storage of each subentry in the line database, and the position of the line database in the CBTC simulation system, at last, the interfaces for other parts.The author focused on what is the simulated/simulation system, and the working principles and advantages of the simulated/simulation system. And the paper emphasized the structure of CBTC analog/simulation system, why we need map the line database with the ATS show, and put forward two data mapping methods.Finally we introduced the structure of the management software for the line foundation database and the design results of the simulation system, at last the outlook of the next stage.更多还原
