 基于LABVIEW的网络化虚拟仪器设计
 
  [摘要]：虚拟仪器是计算机技术与传统的仪器仪表技术结合的产物，是对传统仪器概念的重大突破，必将成为测试仪器的主流。虚拟仪器必须与IT相关技术同步才具有生命力，正如计算机技术的出现和发展促进了虚拟技术的产生和推广应用，引发了测试技术领域的一场革命。
    传统的机械测试技术也正日益向着速度化、自动化、智能化、集成化等方向发展。因此基于虚拟仪器技术的面向工程技术领域的自动测试分析系统的研究和开发日益增多，本文正是基于这一前提，分析研究了基于虚拟仪器技术、以LabVIEW软件为开发平台的自动测试分析系统的开发思想，开发方法，和开发过程，提出了一套基于多功能数据采集卡和图形化编程语言LabVIEW的虚拟仪器构建方案:即建立自顶向下的程序结构，将系统划分为若干独立的功能模块，对每一个功能模块都编制一个独立的子VI，当需要运行该模块的功能时，由上级模块(上级VI)调用该模块对应的子VI，实现该模块对应的功能。本文以一个自动测试分析系统的开发为例，具体说明了从硬件系统到软件系统各功能模块的设计思想和设计过程:其中详细的详细介绍了数据采集模块，信号发生模块，信号分析模块等子模块的设计思想和设计方法，并对各模块的功能进行了试验测试。
    本文分析了虚拟仪器技术未来发展的方向，虚拟仪器必将在未来的工程测试领域逐渐代替传统仪器的地位，实现测试技术领域内的彻底革命。

The Design of Network Virtual Instrumentation
Based on the LabVIEW

  [Abstract]:As a result of the combination of computer technology and instrument technology, Virtual Instrumentation technology has broken through old concept of instrument and will become artery of measuring system. The future of virtual instrument have to bond to related IT technology, just like the presence and development of the computer technology increases the invention and application of virtual technology, which exploded a technical revolution in the measuring technology area.
    Traditional mechanical  measuring technology is stepping into rapidity,
automatization, intelligentization and integration. So the research and development for the automatic measuring and analyzing system, which is based on the virtual instrument technology and applied in the engineering area, are increasing sharply. According to this  situation, this thesis does some research work about the developing thinking, developing solutions and developing process of the automatic measuring and analyzing system based on the virtual instrument technology on the software platform, LabVIEW. This thesis presents a set of schemes for the virtual instrument construction, which is based on the mufti-function data-acquisition card and  graphic programming language LabVIEW: to build the program with a top-to-bottom structure, which divides the system into several independent function modules and designs a independent sub-VI for each single module, when the superior module calls a certain sub-module, then run the sub-VI related to thesub-module, in order to carry out the module's function.
