地铁正线信号平面图的设计及其辅助软件的开发

地铁信号平面布置图是依据地铁线路图绘制的有关信号设备布置情况的平面图纸,它是信号系统后续图纸设计的基础。在总结国内多条地铁线路平面图布置情况的基础上,对平面图的组成元素和图例、各类重要的信号设备(信号机、转辙机、计轴、应答器、车地通信设备、车站站台设备等)的布置方法进行研究和归纳总结,并以单渡线车站为例,给出其轨旁设备布置样例,说明设备设置作用以及坐标计算方式。为进一步提高平面图布置的工作效率,基于Auto CAD软件进行二次开发,应用ObjectARX开发工具包,研发出快速布置典型车站信号设备的辅助软件。

Design of Subway Signal Equipment Layout Diagram and Development of Its Drawing Software

The subway signal equipment layout, which is drawn based on the subway line diagram, is the basis for designing all subsequent diagrams. Multiple signal layout diagrams of domestic subway lines, constituent elements and illustrations of the layout diagram, and layout methods of all kinds of important signal equipment (signals, switch machines, axle counters, balises, train-ground communication equipment, platform equipment, among others) are given and studied. A single crossover station is taken as an example, its signal equipment layout is given, and equipment function and a coordinate calculation method are illustrated. A rapid and efficient drawing software for the signal equipment layout diagram is developed based on AutoCAD ObjectARX technology.
