【摘要】 目前,矿井通风系统管理中存在着一些问题,本文应用虚拟现实技术理论,并在科学解算风网的基础上,以Windows2000/NT系统中调用VisualC++6.0为编程环境,应用OpenGL技术作为图形生成的接口,开发出了虚拟现实矿井通风系统应用软件;该应用软件能明显改善通风系统的现状,并对矿井的改扩建、风网系统的改造等起一定的预测作用,有利于矿井通风的决策管理。 本文全面论述了虚拟现实技术的相关知识、矿井通风的基本概念、矿井三维空间的生成以及在此基础上实现相关的辅助功能,如缩放、变换、漫游等;另外,本文详细介绍了风网解算程序和图形绘制程序的理论基础、设计思想和步骤、绘制模型、生成实例等,从而充分论证了软件系统的可行性,并为以后进一步的改进该系统奠定了基础。 一方面,通过本软件系统,可以改变通风系统的相关设施或设备的参数,来调节通风网络,达到优化通风系统的目的;另一方面,软件系统还具有数据仓库和报表处理系统,从而完善了系统的功能。 最后,本文就应用研究中取得的进步和存在的问题进行了总结,并提出了以后的发展方向和改善意见。更多还原

【Abstract】 At present, there are some problems in the mining ventilation management system. Based on the ventilation network solution scientifically,and applied the theory of Virtual Reality technology ,the paper researched the application software exploitation of mining ventilation system with Virtual Reality.This software transfered Visual C++6.0 as the program settings of Windows2000/NT , the technology of OpenGL as the interface of graphics drawing. This application software can improves the current state of ventilation system obviously.It also has definite forecast effects to the revising and extending of mine,to the alteration of ventilation network,and it is available to the decision-making and management of mining ventilation.The paper completely introduces the correlative knowledge of Virtual Reality technology,the basic conception of mining ventilation,the 3D space drawing of mine. It also introduces the corresponding assistant functions, which based on the drawing ,such as zooming, transforming, walking- through ,ect.In addition,the paper preciously presents the theory foundation of ventilation network solution program and the graphics drawing program, design-considerations and processes, rendering model, practical example ,ect. Thereby,it adequately demonstrated the feasibility of software system,and it also established the base of delivering the system more ameliorations in the future.On the one hand , in order to optimize ventilation system ,utilizing the software system,users can change the parameters of relevant establishments or facilities to adjust ventilation network .On the other hand,the software system also hasdatabase and disposal system of report forms,so as to perfect the functions of system.At last, within the application research of this paper, the obtained progress and some problems were summarized ,and at the same time,the development direction and improvement measures for the future were brought forward too.更多还原
