【摘要】：煤矿生产系统是一个复杂的时变系统,而基于矿井开采的生产方式更增加了煤炭生产过程中的不安全因素。研究表明,对煤矿从业人员进行安全生产培训可以有效地减少安全事故的发生,而传统的培训方式存在形式单一、内容枯燥、缺乏互动等问题。针对这些不足,以某煤矿21304工作面为应用背景,设计并开发了基于虚拟现实技术的综采工作面仿真系统。主要研究内容如下:(1)通过分析综采工作面采煤机、液压支架、刮板输送机及其他机械设备的特点及布局,结合虚拟现实技术在国内外矿业领域应用的研究现状,提出了综采工作面仿真系统的设计方案,并对其关键技术进行了研究。(2)论述了模型创建的流程以及模型优化的技术细节。以采煤机和液压支架为例,详细阐述了几何建模、行为建模、贴图烘焙、灯光布置的建模过程,同时分析了模型渲染输出及导出的流程。(3)基于Unity3D虚拟现实引擎开发了仿真系统的视频学习模块、模拟操作模块和井底漫游模块,并利用Unity3D的粒子系统开发了采煤机喷雾除尘特效和煤块跌落、煤流运动的视觉特效。基于Access数据库和C#语言开发了理论考试模块。(4)利用现代电子技术开发了仿真系统的模拟操作平台,分别就平台的硬件电路设计、软件编程进行研究,利用RS232串行通信接口将模拟操作平台与上位机软件连接,实现系统集成。该系统集视频学习、模拟操作、井底漫游和理论考试功能于一体,具有内容丰富、操作方便、交互友好的特点,弥补了传统培训方式的不足,提高了煤矿企业员工的培训效率,具有广阔的应用前景和推广价值。
[Abstract]:Coal mine production system is a complex time-varying system, and the production mode based on mine mining increases the unsafe factors in the coal production process. The study shows that safety training for coal mine employees can effectively reduce the occurrence of safety accidents, while the traditional training methods have the problems of single form, boring content, lack of interaction and so on. Aiming at these shortcomings, the simulation system of fully mechanized mining face based on virtual reality technology is designed and developed based on the application background of 21304 face in a coal mine. The main research contents are as follows: (1) by analyzing the characteristics and layout of fully mechanized mining face shearer, hydraulic support, scraper conveyor and other mechanical equipment, combined with the research status of virtual reality technology applied in the field of mining industry at home and abroad, The design scheme of simulation system for fully mechanized mining face is put forward and the key technology is studied. (2) the process of model creation and the technical details of model optimization are discussed. Taking shearer and hydraulic support as examples, the modeling process of geometric modeling, behavior modeling, mapping baking and lighting arrangement is described in detail. At the same time, the flow of model rendering output and export is analyzed. (3) based on Unity3D virtual reality engine, the video learning module, simulation operation module and bottom hole roaming module of simulation system are developed. Using Unity3D's particle system, the special effects of spray and dust removal of shearer and the movement of coal flow are developed. The theoretical examination module is developed based on Access database and C # language. (4) the simulation operating platform of simulation system is developed by using modern electronic technology. The hardware circuit design and software programming of the platform are studied respectively. The RS232 serial communication interface is used to connect the simulation operation platform with the upper computer software to realize the system integration. The system integrates video learning, simulation operation, bottom hole roaming and theoretical examination functions. It has the characteristics of rich content, convenient operation and friendly interaction. It makes up for the shortcomings of traditional training methods and improves the training efficiency of the employees in coal mining enterprises. It has broad application prospect and popularization value.
