铁路客运站占线程序图自动化推演系统的开发与应用

Automatic projection system for occupied line program diagram of railway passenger station

为改善铁路客运站基于计算机手动绘制占线程序图的现状,提高客运站日常工作绘图效率,确保客运站到发线运用方案编制的合理性,设计了铁路客运站占线程序图自动化推演系统。构建占线程序图动态绘制算法及仿真流程,实现占线程序图动态绘制、到发线运用方案实时评价及机车车辆作业过程推演。在中国铁路沈阳局集团有限公司大连站的仿真应用表明,该系统简化了占线程序图绘制过程,可实时判断并量化评价方案中存在的冲突,为客运站工作人员编制、优化到发线运用方案提供参考。

In order to improve the current situation of manually drawing occupied line program diagrams based on computers at railway passenger stations,improve the efficiency of daily work diagram drawing,and ensure the rationality of the operation scheme for arrival and departure lines,this paper designed an automated projection system for occupied line program diagram of railway passenger station.The paper constructed a dynamic drawing algorithm and simulation process for occupied line program diagrams,implemented dynamic drawing of occupied line program diagrams,real-time evaluation of operation scheme for arrival and departure lines,and projection of locomotive and vehicle operation processes.The simulation application at Dalian Station of China Railway Shenyang Group Co.Ltd.shows that the system simplifies the process of drawing occupied line program diagrams,can judge and quantify conflicts in the evaluation plan in real time,and provide reference for passenger station staff to prepare and optimize the operation scheme of arrival and departure lines.
