鉴于当前外因火灾救灾中存在的问题，通过火灾救灾与计算机控制技术的结合，构建了矿井火灾救灾计算机控制系统（简称为ＭＦＲＣＣＳ）；设计出其主机支撑软件系统；实现了矿井通风系统及灾变监测与救灾决策、控制过程的三维动画模拟显示；提出了采用对通风系统图形对象进行拓扑分类，通过拓扑类对象的拓扑变形及其组合，实现整个系统图形系统设计的图形设计方法．文中的工作可供构建其它ＭＦＲＣＣＳ时参考． In view of the current problems of external fire disaster relief, through the combination of fire disaster relief and computer control technology, a computer control system for mine fire disaster relief (MFRCCS) is constructed; the host support software system is designed; the mine ventilation system and disaster monitoring And disaster relief decision-making and control process. A graphic design method is proposed to realize topology design of ventilation system graphics objects, topological transformation of topological objects and their combination to realize the design of the whole system graphics system. The work in this article is for reference when building other MFRCCS.
