As a part of the self-adapted yard interlocking system, the main purpose of the research is, by exploring the interlocking relations of the various units one another such as tracks, switches, signals and so on, to find out their forming regulation; in order to cause the operation of the design of yard plane more simple, more sensible and more efficient, we make use of the visual-formed means . then the yard data formed will be provided to the " self-adapt yard interlocking simulation control system " which is developed by the former postgraduate 本系统作为“自适应车站联锁系统”的子课题,其开发的主要目的是:通过对车站站场内股道、道岔、信号机等各部件联锁关系的研究,找出它们之间的形成规律,然后利用可视化手段,简单、快捷地设计出车站站场平面图,并形成原始的站场数据,为已所开发的“自适应车站连锁模拟控制系统”提供数据支持。
