【正文】 相信在不久的將來,一臺裝有虛擬示波器的標(biāo)準(zhǔn)微機(jī)可能成為一個多功能儀器測量系統(tǒng),從根本上改變傳統(tǒng)儀器的研制和生產(chǎn)模式。 LabVIEW 提供很多外觀與傳統(tǒng)儀器(如示波器、萬用表)類似的控件,可用來方便地創(chuàng)建用戶界面。 圖 幅值不變頻率檔位為 10ms/div 2V 不變,輸入信號為 A 時,改變輸入信號的頻率。輸入信號為 A 時,我們,此時波形 A 的峰值電壓為=。按前面所述,把它們的條件均設(shè)置成“1” 、 “2”, “3”三個條件形式。圖 Slope現(xiàn)在,我們創(chuàng)建子 VI(Slope) 。程序圖如圖 、圖 和圖 所示。當(dāng)該結(jié)構(gòu)框圖條件為假時,結(jié)構(gòu)框圖如圖 所示。在游標(biāo)編輯顯示窗中單擊鼠標(biāo)右鍵,選擇創(chuàng)建游標(biāo)選項,進(jìn)入下一級子菜單,在子菜單中選擇【單曲線】 ,在快捷菜單的屬性項中可以設(shè)置游標(biāo)的各個屬性。如圖 所示。示波器的用戶界面如圖 所示 “TIME/DIV”時間/分度選擇旋鈕:顯示頻水平方向上每個格所表示的時間的多少可由相應(yīng)的檔位讀出,一個周期的波形在水平方向上所占的格數(shù)乘以乘以其檔位,即為周期的大小。斷點(diǎn)工具使用斷點(diǎn)工具可以在程序的某一地方終止程序運(yùn)行,用探針或者單步方式查看數(shù)據(jù)。(4)LabVIEW 的暫停。 LabVIEW 的運(yùn)行和調(diào)試 LabVIEW 的運(yùn)行 (1)LabVIEW 的運(yùn)行。圖標(biāo)和連接器(Icon and Connector) LabVIEW 圖形化語言的每個 VI 都有自己的圖標(biāo)和連接器。前面板(Front Panel)前面版是 VI 特有的組成部分之一,用來在計算機(jī)的屏幕上顯示人機(jī)對話、交互式用戶操作界面,亦可構(gòu)成模擬真實儀器的操作面板?,F(xiàn)在,隨著虛擬儀器系統(tǒng)的廣泛應(yīng)用,越來越多的教學(xué)部門也開始用它來建立教學(xué)系統(tǒng),不及大大節(jié)省了開支,而且由于虛擬儀器系統(tǒng)具有靈活、可重用性強(qiáng)等優(yōu)點(diǎn),使得教學(xué)方法也變得更加靈活了。第一個階段是利用計算機(jī)來增強(qiáng)傳統(tǒng)儀器的功能把傳統(tǒng)的儀器通過串行口和計算機(jī)連接起來后就可以用計算機(jī)控制儀器了。這得益于 NI 軟件的靈活性,只需更新計算機(jī)或測量硬件,就能以最少的硬件投資和極少的、甚至無需軟件上的升級即可改進(jìn)整個系統(tǒng)。因此,計算機(jī)技術(shù)在顯示、存儲能力、處理器性能、網(wǎng)絡(luò)、總線標(biāo)準(zhǔn)等方面的發(fā)展,導(dǎo)致了虛擬儀器系統(tǒng)的快速發(fā)展?! ? 關(guān)鍵字:LabVIEW ,虛擬儀器,虛擬示波器 基 于 LabVIEW 的 虛 擬 示 波 器 設(shè) 計 II AbstractVirtual oscilloscope Virtual Instrument Technology ( NI ) using a high performance modular hardware, bined with efficient and flexible software to plete a variety of test, measurement and automation applications. A flexible and efficient software can help you create a fully customizable user interface, modular hardware can provide a full range of system integration, software and hardware platform can meet the standard of synchronization and timing applications. This is the NI nearly 30years always lead the test and measurement industry development trend of the reason. At the same time only with efficient software, modular I / O hardware and software and hardware platform for the integration of the three major ponents, in order to give full play to the virtual instrument technology of high performance, scalability, less development time, as well as excellent integration of these four advantages.Virtual instrument is one of the prominent characteristics is to a large extent with system software upgrade replacement equipment hardware replacement, it will save a lot of capital investment, on behalf of the instrument technology development direction. Now, virtual instrument has been in very large scale integrated circuit testing, analog / digital circuit testing, modern test household appliances, electronic ponents, power electronic device test as well as military, aerospace, biomedical, factory testing, electrical technology in the field of mobile site testing application. Based on virtual instrument technology equipment still requires the use of a data acquisition card data collection work, for further analysis and processing system.Keywords: LabVIEW,Virtual instrument,Virtual oscilloscope 基 于 LabVIEW 的 虛 擬 示 波 器 設(shè) 計 III 目 錄摘 要 ..........................................................................................................................................................IAbstract...................................................................................................................................................II目錄 .........................................................................................................................................................III第
