基于ELVIS的模块化网络教学实验系统开发

Development of modular network experimental teaching system based on the ELVIS

为了构建一个基于虚拟仪器技术的网络化虚拟实验室,首先利用NI ELVIS教学平台设计了一套实验教学系统,然后提出了网络化教学实验系统的软件设计及实现方法。该实验系统采用模块化的设计思想,充分利用了ELVIS的软硬件资源。在现行局域网构架之上,以电工电子教学实验为例,采用LabVIEW程序设计方法,通过LabVIEW服务器端软件本身的Web Server网络通信功能,将实验结果发布到网上,实现了数据的远程访问和共享,达到了构架虚拟实验室的目的。

In order to build a networked virtual laboratory based on virtual instrumentation technology,at the first step,an experimental teaching system is developed with the NI ELVIS teaching platform.Secondly,the software design and the implementation method are proposed to build a networked virtual laboratory.This system applies a modular design concept to take full advantage of the hardware and software resources of the ELVLS teaching platform.On the existing LAN architecture,taking electrical and electronic experimental for example,the test results can be transmitted to the website by using the Web Server network communication function in the LabVIEW server software itself to realize the data remote access and sharing.With the LabVIEW programming design approach,the goal of building an architecture of virtual laboratory is achieved.
