摘　　要：城市轨道交通CBTC(基于通信的列车自动控制)信号系统区域控制器(ZC)目前存在大量线路数据需人工录入且线路数据存储与访问效率较低的问题。为此,文章提出一种线路数据自动生成方法,其采用有向图描述线路拓扑,对线路数据实体关联关系进行分析与设计,提高了线路数据的生成效率、准确性以及主机应用软件运行速度;且采用统一建模语言(UML),缩短了设计时间,降低了改进成本。仿真结果验证了该方法的可行性和准确性。The current CBTC（communication based train control） signaling system has the problems that its ZC（zone controller） has a large amount of line data to be manually entered and the line data storage and access is of low efficiency. In this paper, it proposed a method for line data automatic generation, which uses directed graphs to describe the line topology, analyzes and designs the relationship between line data entities, improves the efficiency and accuracy of line data generation, and the speed of host application software. UML is used to shorten the design duration and reduce the cost of improvement. Simulation results show the validity and the correctness of this method.
