摘　　要：研究列车在站技术作业时间查定与管理现状,立足实践,设计列车在站技术作业时间写实管理信息系统。基于现有的铁路技术作业相关流程及查定模式和C/S模式,采用面向对象的系统设计方法,提出“1主1辅3层次4应用”的系统总体结构与分层结构,详细设计了数据获取、数据汇总与处理、数据统计与分析等功能,阐述数据结构设计、分布式数据查询优化等系统关键问题的解决方法。该系统可解决部分列车习惯性晚点的问题,在一定程度上提升列车运行的正点率。This paper studied the current situation of the determination and management of train technical operation time at the station,and designed a realistic management information system for train technical operation time at the station based on practice.Based on the existing railway technical operation related processes,determination mode and C/S mode,the overall structure and hierarchical structure of"1 main,1 auxiliary,3 levels and 4 applications"system were proposed by using object-oriented system design method.In this paper,functions of data acquisition,data aggregation and processing,data statistics and analysis were designed in detail,the key problems of the system such as data structure design and distributed data query optimization were discussed.The design of this system can solve the problem of habitual delays of some trains,improve the punctuality rate of train operation to a certain extent.
