【摘要】：实验教学是理工科中职院校日常教学中非常重要的一个环节。随着计算机技术和网络技术的迅速发展,一种新的教学模式——远程网络教学应运而生。把远程网络教学和实验教学相结合,构建一个远程虚拟实验教学平台,可以有效地解决传统实验室易受实验设备、时空、成本等因素影的问题,实现高效、快捷和创新实验。本文首先根据虚拟仪器实验平台的技术要点和中职院校电类专业实验的实际需求,确定出适合本实验平台的硬件设备以及实验方案;其次,对组网模式进行分析比较,找到适合该平台、方便用户使用的B/S组网模式;然后,以Lab VIEW为软件开发工具,完成了中职院校电类专业中的八个实验的设计,这八个实验分别为二极管伏安特性测量实验、JK触发器虚拟实验、移位寄存器虚拟实验、计数器虚拟实验,一阶低通电路频率响应虚拟实验、RLC串联电路的频率特性实验、三要素法求解一阶动态电路实验、二阶电路的零输入响应实验;再次,用Dreamweaver设计好虚拟实验平台的网站内容,利用远程面板将网页制作技术和远程VI面板连接技术结合,实现了虚拟实验的远程发布;最后,建立利用IIS服务器建立Web站点,并通过用户的远程登陆,验证了实验平台的可操作性。
[Abstract]:Experimental teaching is a very important link in the daily teaching of secondary vocational colleges of science and engineering. With the rapid development of computer technology and network technology, a new teaching model-distance network teaching came into being. By combining distance network teaching with experimental teaching, a remote virtual experimental teaching platform can effectively solve the problems of traditional laboratories' vulnerability to experimental equipment, time and space, cost and other factors, and realize efficient, fast and innovative experiments. Firstly, according to the technical essentials of virtual instrument experimental platform and the actual demand of electrical specialty experiment in secondary vocational colleges and universities, the hardware equipment and experimental scheme suitable for this experimental platform are determined. Secondly, the network mode is analyzed and compared. Find the B / S networking mode which is suitable for the platform and convenient for users. Then, with LabVIEW as the software development tool, we have completed the design of eight experiments in the electrical specialty of secondary vocational colleges. The eight experiments are JK flip-flop virtual experiment, shift register virtual experiment, counter virtual experiment, frequency response virtual experiment of first-order low-pass circuit and RLC series circuit. The three-factor method is used to solve the first-order dynamic circuit experiment and the zero-input response experiment of second-order circuit. Thirdly, using Dreamweaver to design the content of the virtual experiment platform, the remote panel is used to combine the web page making technology with the remote VI panel connection technology. Finally, the Web site is established by IIS server, and the operability of the experiment platform is verified by the remote login of users.
