Abstract: 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.
