摘要
虚拟实验是将计算机技术应用于工业研发和实验教学的一个重要手段。针对目前微机接口实验模式存在的不足,提出设计虚拟实验系统的方法,利用Windows下的VDD技术,对用户实验程序中的I/O指令进行拦截,设计出一套用于仿真接口器件的实验系统。实验灵活,不占用额外的系统硬件资源,极大满足了实验教学的需求。
The virtual experiment is an important means of the computer technology for industrial research and experimental teaching. Analyses the disadvantages of the traditional microcomputer inter- face experiment, then advances the method designing a virtual experiment system. It uses VDD technology in Microsoft Windows system, hooks the user experimental program I/0 instructions, and designs an experiment system to simulate the interface devices action. Experiment has hight flexibility, and does not take up additional system hardware resources, can greatly meet the needs of the experimental teaching.
