网络虚拟实验室的研究

Research of network virtual lab

介绍网络虚拟实验室的特点:与现实的一致性(或现实的延伸);高度交互性;实时的信息反馈．然后从实现原理和软、硬件组成等方面较详细地论述了构建基于虚拟仪器的网络实验室的方法,包括客户端/服务端/数据库/应用程序结构,软件中的模拟仿真和实时测量两个组成部分和以NI-PXI作为核心、以一台Dell PowerEdge4600为Web服务器的硬件体系。接着指明网络虚拟实验室的协作式、自适应的发展方向,提出建设该实验室应注意的问题。

The characteristics of a network virtual lab is introduced at first, including coherence with reality （or extend of reality）, high cooperativity and real-time information feedback. Then a method is proposed in detail to build up a network lab based on virtual instrument at aspects of principle and structure of software and hardware. That includes the program structure of browser/server/database/application, two composing parts of simulation and real-time measure in software and hardware frame which centers on NI-PXI structure and uses a Dell PowerEdge4600 as web server. Finally, some evolution directions are discussed such as cooperation and adaptive and matters worthy of being noticed while establishing a network virtual lab.
