摘要:

为探讨虚拟现实技术应用于矿物加工设计的可行性,基于虚拟现实平台——虚幻引擎4的蓝图系统开发了桌面式磨矿分级工艺自主设计系统。根据磨矿分级工艺设计过程的具体特点,将设计过程中的经验公式、经验数据及设备选型计算的人工智能算法转化为虚幻引擎蓝图系统的语言模型,较好地解决了磨矿分级工艺设计过程中的经验数据、经验公式以及设备选型参数和选型方法的处理问题。基于虚拟现实技术的磨矿分级工艺设计系统,根据用户提供的原始数据和指标,通过后台计算设计出最终方案。本系统的开发,证明采用虚拟现实技术处理磨矿分级工艺设计问题是可行的,为后续实现基于虚拟现实技术的磨矿车间设备配置设计创造了条件。

Abstract:

To discuss the feasibility of the application of virtual reality technology in mineral processing design,and to solve the problems of long design cycle,low design efficiency and boring design process,which still exist in traditional mineral processing design,a desktop auto-design system of the grinding-classification process was developed in combination with the rapidly rising virtual reality technology.The development of this system takes virtual reality technology platform Unreal Engine 4 as the carrier,and relies on its Blueprint system and Unreal Motion Graphics UI Designer editor to build the whole process.In the process of development,focusing on the empirical formulas,empirical data,equipment selection parameters and equipment selection methods in the traditional grinding and classification process design,the blueprint programming language was used to transform them into a computer-based independent design method.The empirical formulas with complex structure,variable parameters and repeated use are converted into Blueprint system function or macro,the corresponding data of the table are stored as Blueprint array,the value range data are fitted into interpolation function,power function and other mathematical models,and then all of them are stored in the Event Chart of the Blueprint system.Simulation designer in the traditional design methods,using Blueprint design language to write algorithm procedures.After programming and testing,the system is compiled and packaged with Visual Studio 2019,and the Unreal Editor is used to release the Windows version for users to use.According to the original ore data and ore-dressing indexes input by the user,the system recommends the appropriate grinding process,and then,according to the recommended grinding classification process,carries out the calculation of ore volume and pulp indexes,grinding and grading equipment selection calculation,auxiliary equipment selection calculation,etc.,and finally forms a reasonable grinding classification process design scheme.In the process of system design,users can also reasonably change the conditions in the process according to the design requirements.The development of this system has proved that the application of virtual reality technology in mineral processing design is feasible.It has created conditions for the following development of the grinding workshop configuration design system based on virtual reality technology,and also provided useful reference for virtual reality technology to integrate into the mineral processing field.

Key words: mineral processing design, grinding-classification process, visual reality technology, system development, Unreal Engine
