摘  要
 目前，在中國(guó)許多高校中使用的教學(xué)儀器，仍大多為傳統(tǒng)儀器。隨著科學(xué)技術(shù)的不斷發(fā)展以及相應(yīng)學(xué)科高等教育課程教學(xué)內(nèi)容的更新，傳統(tǒng)儀器日益暴露出一些缺陷和不足。為了改善實(shí)驗(yàn)條件，改善實(shí)驗(yàn)教學(xué)方法，更新實(shí)驗(yàn)教學(xué)內(nèi)容，提高實(shí)驗(yàn)教學(xué)課程的開設(shè)水平，把虛擬儀器引入實(shí)驗(yàn)教學(xué)已成為一種趨勢(shì)。本文就是基于虛擬儀器在電機(jī)方面的應(yīng)用設(shè)計(jì)。
 虛擬儀器是現(xiàn)代計(jì)算機(jī)計(jì)算和儀器技術(shù)相結(jié)合的產(chǎn)物。將虛擬儀器技術(shù)引進(jìn)實(shí)驗(yàn)教學(xué)，目的是更新實(shí)驗(yàn)設(shè)備，降低實(shí)驗(yàn)設(shè)備購(gòu)置費(fèi)用，減小實(shí)驗(yàn)測(cè)量過(guò)程中的人為誤差，提高實(shí)驗(yàn)測(cè)量的準(zhǔn)確度；在激發(fā)學(xué)生自主學(xué)習(xí)的積極性、促進(jìn)學(xué)生動(dòng)手實(shí)踐和增強(qiáng)創(chuàng)新意識(shí)的方面意義重大。
 本文以美國(guó)NI公司的Labview 7.1為軟件開發(fā)平臺(tái)，以電機(jī)的數(shù)學(xué)模型為基礎(chǔ)，對(duì)電機(jī)進(jìn)行整體虛擬，建立電動(dòng)制動(dòng)過(guò)程的電流VI模型，進(jìn)而設(shè)計(jì)出可以應(yīng)用于實(shí)驗(yàn)教學(xué)的電機(jī)實(shí)驗(yàn)。
   本文首先介紹課題的研究背景及研究的意義，并陳述了本文的主要內(nèi)容；然后介紹了本課題的研究工具——虛擬儀器，闡述了它的定義、組成、功能、特點(diǎn)及發(fā)展前景；接著介紹了虛擬儀器的開發(fā)環(huán)境——Labview軟件，總結(jié)了Labview軟件的特點(diǎn)，簡(jiǎn)單地介紹了它的操作工具，除此之外還對(duì)G語(yǔ)言編程作了介紹；接下來(lái)對(duì)數(shù)據(jù)采集以及與其相關(guān)的信號(hào)調(diào)理、儀器驅(qū)動(dòng)、緩沖觸發(fā)的基本概念作了說(shuō)明；然后重點(diǎn)針對(duì)所設(shè)計(jì)的實(shí)驗(yàn)——基于Labview的電機(jī)制動(dòng)過(guò)程的觀測(cè)與分析，從模型建立、功能介紹、程序說(shuō)明、實(shí)驗(yàn)結(jié)果等方面作了詳細(xì)的闡述；最后是本文的結(jié)論，對(duì)整個(gè)設(shè)計(jì)進(jìn)行總結(jié)。

 Abstract
At present, many colleges and universities in China, the use of teaching equipment, are still mostly traditional instruments. With the continuous development of science and technology subjects and the corresponding higher education courses to update teaching content, the traditional instruments revealed the growing number of deficiencies and shortcomings. In order to improve the experimental conditions, experimental teaching methods to improve and update the contents of the experimental teaching to improve the experiment the level of teaching curricula, the introduction of the virtual instrument experimental teaching has become a trend. This article is based on virtual instrument applications in the electrical design.
Virtual instrument of modern computer technology and equipment, a product of the combination. The introduction of virtual instrument technology to experimental teaching, the purpose is to update the laboratory equipment, laboratory equipment to reduce acquisition cost, reducing the experimental measurement in the process of human error, improve the accuracy of experimental measurements; stimulate students in learning self-promote students hands-on experience and strengthen their sense of innovation of great significance to the area.
In this paper, the United States, NI's Labview 7.1 software development platform to the motor mathematical model based on the overall virtual machine, the process of establishment of electric braking VI of the current model, which can be applied to the experimental design of the motor teaching experiment.
This paper first introduces the topic of the research background and significance of the study and presented the main contents of this article; and then introduced the subject of the research tools - Virtual Instrument, the definition of its form, function, characteristics and development prospects; then introduced a virtual instrument development environment - Labview software, summed up the characteristics of Labview software, a simple introduction to the operation of its tools, in addition to the G programming language was introduced; next to the data acquisition and the associated the signal conditioning, instrument drivers, the basic concept of the trigger buffer described; and then focusing on the design of the experiment - based on the electric brake Labview observation and analysis process, from the model, functions, the program shows that the experimental results aspects in detail; Finally, the conclusions of this article, summed up the entire design.
