确定双线自动闭塞区段各种扣除系数的微机交互系统

A MICROCOMPUTER INTERACTIVE SYSTEM FOR DETERMINING THE VARIOUS REMOVAL COEFFICIENTS OF SCHEDULING TRAINS IN DOUBLE TRACK AUTOMATIC BLOCK DISTRICTS

本文提出了将计算机模拟人工与CAD技术结合在一起,通过铺画区段最大列车运行图来确定双线自动闭塞区段各种列车扣除系数的新算法,解决了国内现有电算方法只能孤立地确定旅客列车扣除系数的问题。文中有关铺画旅客列车、货物列车运行线,特别是计算市郊、摘挂列车轮廓方案的理论以及将区段一昼夜的全图作为一个计算整体的观点充实了现有计算机编图理论的内容。采用高级语言与微机AUTOCAD绘图软件包接口的计算软件能根据要求提供各种列车扣除系数及区段最大列车运行图,后者在人工或计算机编制列车运行图时作为检查区段通过能力的标准尺度具有一定的现实意义。

Combining the simulation of the human work by computers with CAD technology to determinethe removal coefficients of scheduling various kinds of trains in double track automatic block districtsthrough working out the section train diagram of maximum carrying capacity, this paper presents anew algorithm to improve the current method which only isolatedly determines the removal coefficientof scheduling passenger train. The view point on regarding the outlining of passenger train path,freight train path, especially the contouring of the scheme of suburban train, mixed unit train and thewhole section train diagram of day and night as one calculation unit enriches the current theory ofdrawing train diagrams by computers. This system. implemented as interfacing software by using high-level computer language and AUTO-CAD software, can determine various removal coefficients anddraw the section train diagram of maximum carrying capocity, which may be considered as a criterionin scrutinizing the carrying.capacity of traindiagrams worked out manually or by computers.
