摘要
描述了将Map应用于有轨交通地理系统的一种普遍方法,既可实现调度系统的命令表示、轨道电路的占用、道岔定反位表示等,也可实现车辆的实时动态监控。设计了一种方法使得基于图的控制既具有相当的地理精度,又可避免某些区域如站台因为行车设备过分集中导致的图的堆叠问题。描述了运用图论的方法为线路建立拓扑,在MapX中表示拓扑关系。阐述了MapX坐标系及其与其他坐标系的转化,实现道岔、信号灯、故障等表达和控制,以及在MapX中实现层和图元的控制。
The method of how to use electronic map in railway and metro geographic system is described in this article. In this way, we can not only realize the dispatch management such as occupation of track circuit, switch of turnout, select of route but also can realize monitoring the train dynamically. Through the method the geographic system can be controlled with high accuracy without the problem that some road equipments overlapping on others in specific area such as station. We described how to bulid topology for the geographic system in MapX,how to translate between MapX coordinate system and other system,how to express and control equipment such as turnout ,signals and how to realize the control of layers and graphic elements in MapX.
