利用VB语言实现虚拟电子实验

文章研究阐述的虚拟模拟电路仿真实验是用VB编程技术来实现的。根据不同的实验内容和要求,使用系统提供的各种元件(如电阻、电容、二极管、三极管、集成运放),芯片(如74LS00、74LS20、74LS74、74LS87、74LS138、555等)和仪器仪表(万用表、信号发生器、交流毫伏表、示波器、试验箱),任意搭接连线,大多数电子电路实验都可以在该系统上完成。实验结果和现象利用交流毫伏表、示波器等进行检测和观察,实验操作及过程模拟实际工作环境。实验系统借助Internet,可实现网络运行。虚拟实验室不受时间及空间的限制,受教育的范围之广是任何实验室无法比拟的,学生学习可以不受地理环境、时间、年龄、职业的限制,可以根据各自的学习习惯灵活机动地安排自己的学习时间。在需要的时候任何人只要与Internet互连,就可以在任何地方机会均等地接受同样的教育,接受网络为他们提供的完整的知识信息和技能培训。

This paper studies the development of multimedia electronic technology experimental system is VB programming techniques to achieve. Depending on the experimental content and requirements, using the system provides a variety of components, chips and instrumentation and so on, any lap connections, most of the electronic circuit experiment can be completed on the system. Experimental results and the phenomenon of using 'virtual instruments', such as multimeters, oscilloscopes and other testing and observation, experimental operation and the process is almost identical with the actual feelings. Experimental system using Internet, online operation can be realized. Virtual laboratory is not time and space constraints, which for the time part-time students have a very big help. Such students can not geographical location, time, age, occupation restrictions, in accordance with their study habits flexibility in arranging their own study time. When needed, anyone with Internet interconnection, you can place in any equal opportunity to receive the same education, access to the network to provide them with complete knowledge and information and skills training.
