基于WEB的远程网络虚拟实验实现

Actualize the Virtual Experiment of Long Range Network Based on WEB

在介绍虚拟仪器(VI)技术和面向Internet的Web技术基本理论的基础上,把虚拟仪器(VI)的前面板移植到WEB页面上,通过WEB服务器处理相关的测试需求,将WEB和虚拟仪器(VI)结合起来,使虚拟仪器扩展到真正的分布式网络测试应用环境中去,对于充分合理地利用有效资源,进行远程实验教学及远程测控都有着很好的作用,而且,价格低廉,性能优越,扩展性好,使用极其方便。利用美国国家仪器公司(National Instruments)推出的虚拟仪器设计软件LabVIEW开发基于WEB的虚拟实验。文中将以构建双极型单管交流放大器虚拟实验为例,介绍基于WEB的虚拟实验实现方法。

This article is introducing the Basic theories the WEB technology of facing to the internet. It also tell on the virtual instrumental（Ⅵ） technology and us how to transfer to the page of WEB from the front panel of the virtual instrument （Ⅵ） and how to deal with relevant requirements of all kinds of measurement through the WEB server. Connecting the web with the virtual instrument（ Ⅵ）, we can expand the virtual instrument into a real distributing web measuring environment. It is all of great use to make good use of the efficient resources, carry on the long range experiment teaching and long range measure. In addition, it is cheap with good performance and high expansibility, and it can be used very conveniently. This article makes use of the LabVIEW which is a design software about the virtual instrument belong to the national instruments company in American and developments the virtual experiment based on WEB. This article will take the experiment in which we will set up the virtual experiment on two poles of single tube enlarger for alternate current, and introduce the methods about carring out the virtual experiment based on WEB.
