【摘要】 本课题改善了当前传统的封闭式教学模式，对实验教学模式进行了创新。电子实验室的逐步开放，用户信息、实验数据的急速增加，海量的数据信息已经使得传统管理模式不能胜任现有的实验管理工作。因此，必须建立开放式实验室，让学生根据自己的兴趣爱好选择自己擅长的实验，反复地进行电路测试和故障查询，通过选择最佳的实验方案，采用优越的实验手段使得实验结果达到最佳。应用计算机科学、仪器技术和网络技术给电工电子实验室的发展注入活力。网络技术在仪器领域的渗透日益加深，将信息系统和测量系统通过Internet或Intranet无缝地连接起来，将现有的电子实验室建设成虚拟网络实验室，最大限度地做到资源共享。本文分析了虚拟仪器的研究和开发，给EDA实验建设提供了新的思路。本文就开发的几款电工电子学常用的虚拟仪器，并自行搭建了一些小规模的实验平台，遵循电工电子实验的教学特点，结合电工电子实验的实例，将传统仪器和虚拟仪器的优缺点进行比较，分析已开发的虚拟仪器目前存在的一些优缺点。另外，还介绍了作者参与开发的实验管理系统平台，该平台为开放式虚拟网络实验室的搭建提供了基础；在文章的最后，对虚拟网络实验的功能、结构和实验方案作了详细的分析。开放式虚拟网络实验平台正在进一步建设和完善中，目的是让学生无论位于哪个地方，只要有网络和电脑，就能进行电工电子实验。本项目涉及电工电子实验的仪器设计以及实验管理系统的应用与开发。拟解决的工程设计技术问题难度较大，工作量较大，该项目的圆满完成，为实验教学的改革提供了有益的建设性经验，研究成果在高校中有实际应用价值和推广价值。更多还原

【Abstract】 This paper discribes a project which improves the old closed teaching mode and make some innovations to Lab-teaching. With the gradually opening of electronics laboratory , as well as the rapid increasement of user information and experimental data, a mass of data makes old management mode is unable to meet the need of experimental information management. Therefore, it is necessary for us to build an open laboratory, students can choose the optional experiments of their own according to their interests. By repeated circuit testing and fault inquiring, students can find a best way for experiments and produce good results. The development of applied computer science, instrumental technology and network technology ingect great vitality to the Electronic Laboratory. When web technique expands to the region of instrument, information system and measurement system can be linked with no seam, so current electronic laboratory can be developed to be a kind of virtual web laboratory through Internet or Intranet, which makes the limited resources can be shared furthest.The research and development of Virtual instruments are decribed in this paper, which bring new idears to the construction of EDA laboratory. The author have tried to developed a few kind of virtual instruments which usually have been used in electric electronics experiments, and build a small-scale experimental platform. Combining the features of experimental teaching of Electrical and Electronic, we do some comparisons between traditional instruments and virtual instruments, and make analyses of the existing shortcomings of current virtual machines. In addition, a experimental management system has also been introduced in the paper, which involved me more than half year to do research about it. The experimental management system provide a foundation for the Open Laboratory. In the end, the author focuses on the structure and functions of virtual instrument, as well as a few methods of the implements of the whole VI platform. The opening virtual network laboratory is now in futher improvement. It aims to provide good service to the students and teachers and make them get access to the laboratory whenever and wherever as long as they are on Internet or Intranet.The project introduced in this paper is involving virtual instruments designing and development and its application of experimental management system. The engineering problems of designing to be solved in this project are difficult and includes great massive work. The full completion of the project brings some benefitial designing experience for experimental teaching innovation. Also, it has great value in application and expanding in other universities.更多还原
