摘　　要：针对传统的微机接口课程实验的开展受到时间、场所以及实验设备等原因的限制问题,研究并设计了3D虚拟仪器实验控制系统;传统微机实验需要在规定的时间到实验室去进行,学生接触实验仪器的机会较少,极大地降低了实验教学效果;为解决这一问题,通过对面向对象设计思想的分析,设计了一种基于3D组件的虚拟仪器实验控制系统,并对实现过程做了详细分析。系统分为3D组件可视化建模和虚拟实验场景的构建以及实验组件的功能建模3个部分,首先利用3dmax的模型生成能力对虚拟实验所需的组件进行了可视化建模,然后根据OpenGL的模型导入、材质重装技术在VS平台上将3D实验元件导入到虚拟实验场景中,最后对实验组件进行功能建模,完成虚拟仪器交互实验;根据此虚拟实验系统,开展了微机接口课程中的8255控制交通灯实验,结果表明了该实验系统的可行性。As to the problem of the traditional microcomputer interface experiments＇ implementation being limited by place, hour and ex perimental devices, the system of virtual instrument experiment was researched. In order to overcome the loss of device＇s price and limit ap plication, the system of virtual instrument based on 3D components which came from the theory of object oriented designing. The system in cludes three parts： 3D components visible modeling, virtual experimental sign arranging and components＇ function structure. Firstly, the 3dmax was used to create experimental components, and then 3D models were put into VS platform by OpenGL. Finally, the interaction vir- tual experiments could be completed after the function of models being endowed. According to the system, the ＇ 8255 and traffic light control- ling＇ experiment has been developed. The result shows that the system is available.
