矿井通风系统可视化固定宽度巷道双线处理

Fixed distance double line automatic treatment of tunnel coordinates in mine ventilation visualization

基于通风系统图上通风网络拓扑关系自动建立的基础上,系统地研究矿井通风系统图巷道连接关系,提出并实现用固定显示设备宽度双线表示巷道,双线坐标自动计算。整个系统采用面向对象程序设计方法,利用C++语言实现。通过图形管理对象、巷道集合对象、节点集合对象,巷道对象和节点对象之间相互发送和接收消息来实现双线坐标计算的自动实现。该方法具有普遍性、计算量小,速度快,执行效率高等特点。

This study is based on topology of mine ventilation network, after research on the relationships of the connection types among the tunnels, a new method is used which uses fixed view device width double line to express mine ventilation system graph and the tunnel＇s coordinates of double line is computed automatically for the first time. This system uses object-oriented programming method, implemented by using C＋＋ computer language. This method is realized by sending and receiving messages among graph managed object, tunnel set object, joint set object and tunnel objects and joint objects. This method has the characteristics of generality, less calculation, high velocity, high efficiency and etc.
