城市轨道交通信号系统线路数据自动生成系统研究

Research on line data automatic generation systems for urban rail transit signal systems

在城市轨道线路日益增多的现状下,线路数据量随之变的越来越庞大。现有城市轨道交通信号系统中的线路数据多采用人工输入方式,耗时长且易出错。对此,建立一种城市轨道交通信号系统线路数据自动生成系统。该系统能够快速、准确地由CAD线路单轨图生成各子系统需要的所有线路数据表,可极大地提升城市轨道交通信号系统中线路数据输入效率,同时避免由于CAD线路单轨图中元素发生改变而人工更新不及时导致的线路数据表遗漏的风险,从而保证各子系统间线路数据版本的统一性。该系统的合理使用可为城市轨道线路数据的采集、存储及使用节约大量时间及人力成本,进而提高城市轨道交通的经济效益。

As urban rail networks continue to expand,the volume of line data has also grown significantly.In current urban rail transit signal systems,line data is often manually input,which is both time-consuming and prone to errors.Accordingly,this study establishes an automatic generation system for the line data of urban rail transit signal systems.This system can quickly and accurately generate all the line database tables required by each subsystem from CAD line monorail diagrams.This approach significantly improves the efficiency of line data input and reduces input errors in the urban rail transit signal system.Meanwhile,it also avoids the risk of omitting line data sheets due to changes in the elements of CAD line monorail diagrams and untimely manual updates.Consequently,this ensures the uniformity of line data versions among subsystems.The rational utilization of this system could save a lot of time and labor costs for the collection,storage,and use of urban rail line data,thereby boosting the economic benefits ofurban rail transit.
