【摘要】：“微机原理与接口技术”是电子类学科专业的必修专业基础课程,在工程实践性方面要求很强。传统实验存在的一些缺点,虚拟实验的出现很好的解决了传统实验成本高、实验模块固定等问题,为实验者提供了一个自主实验的平台。本文针对原有虚拟实验研究存在的不足和未涉及的方面,利用VC++结合3DMAX和OpenGL技术,设计开发一个三维可视化的微机原理与接口技术虚拟实验系统。该系统的实验元件以三维形式呈现,利用方向包围盒OBB方法进行碰撞检测,避免元件在移动过程中两两发生碰撞,解决实验失真问题,并且实现了元件交互功能,包括线路连接、移动、旋转、删除等功能。论文首先简单介绍了虚拟实验研究现状及发展趋势,接着对微机接口虚拟实验系统总体设计研究探讨,提出一个功能完善的实验系统应包含实验查看、程序设计、电路设计、实验运行、元件库管理、实验报告等六大功能模块,且描述实验者在微机接口虚拟实验系统进行实验的操作流程；概述实现三维可视化虚拟实验系统需要的几种相关技术；提出一种虚拟实验元件的数学模型以及可视化方法,并在此基础上对虚拟3D实验元件8255并行接口和交通灯进行建模并作了可视化处理;在虚拟实验中实验元件的碰撞检测非常重要,因此论文探究了基于方向包围盒OBB的实验元件碰撞检测。最后利用相关研究成果设计实现了三维可视化的微机接口虚拟实验系统,通过8255接口控制交通灯的实验示例介绍基于该虚拟实验系统的实验方法。实验表明三维可视化的微机原理与接口技术虚拟实验系统在实验教学领域具有实际使用价值。
[Abstract]:"Microcomputer principle and Interface Technology" is a compulsory basic course for electronic subjects, which requires very strong engineering practice. The appearance of virtual experiment solves the problems of high cost and fixed module of traditional experiment, which provides a platform for the experimenter to experiment independently. In this paper, a 3D visualization virtual experiment system based on microcomputer principle and interface technology is designed and developed by using VC combined with 3DMAX and OpenGL technology in view of the shortcomings and untouched aspects of the original virtual experiment research. The experimental components of the system are presented in three-dimensional form. The collision detection is carried out by using the directional bounding box OBB method, which avoids the collision of the components in the course of moving, solves the problem of experimental distortion, and realizes the interactive function of the components. Including line connection, movement, rotation, delete and other functions. This paper first introduces the research status and development trend of virtual experiment, and then discusses the overall design of the virtual experimental system of microcomputer interface, and puts forward that a functional experimental system should include experimental view, program design, circuit design, etc. Six functional modules, such as experiment operation, component library management, experiment report, and so on, are described, and the operation flow of the experimenter in the computer interface virtual experiment system is described, and several related technologies to realize the 3D visualization virtual experiment system are summarized. This paper presents a mathematical model and visualization method of virtual experimental element. Based on this, the parallel interface and traffic light of virtual 3D experimental element 8255 are modeled and visualized. The collision detection of experimental elements is very important in virtual experiments, so this paper explores the collision detection of experimental elements based on directional bounding box (OBB). Finally, a 3D visualization virtual experimental system of microcomputer interface is designed and implemented by using the related research results. The experimental method based on the virtual experimental system is introduced by the experiment example of traffic light control with 8255 interface. The experimental results show that the virtual experiment system based on the computer principle and interface technology of 3D visualization has practical value in the field of experimental teaching.
