基于多进程的铁路列车运行图群体协同编制系统

Railway Train Diagram Group Cooperative Making System Based on Multi-Process

本文提出了一种基于多进程技术的铁路列车运行图群体协同编制系统实现方法,即采用多进程技术建立运行图编制系统的副进程,主进程作为运行图编制客户端运行,受权限制约控制,用户利用副进程可进行全路网范围内列车运行图的编制、方案比选等工作,在确定方案可行之后依用户权限由主进程提交给运行图服务器。通过该方法可以确保在不干扰联网编制列车运行图工作进程情况下,缩短运行图群体协同编制协调沟通时间,提高列车运行图的编制、数据处理效率,经实际系统验证确实可行。

Based on the multi-process technique, this study proposed a method to realize a train diagram group cooperative making system. It adopted the multi-process technique to establish a slave process of the train diagram making system, while the master process was running as the train diagram client, was controlled by the permission restriction. Through the slave process, users could make train diagram, as well as compared and selected schemes within the whole railway network. After confirming the feasibility of the scheme, the master process submited it to the train diagram sever according to user＇s right. By this means, it could shorten the coordination and communication time of group cooperative making train diagram, and enhanced the efficiency of train diagram making and data processing, without disturbing the process of making train diagram when connecting to the network. The method was verified by the practice system, and was indeed feasible.
