基于labview的虛擬儀器設(shè)計(jì)實(shí)驗(yàn)-全文預(yù)覽
【正文】 Virtual instrument Engineering Workbench）是一種圖形化的編程語言開發(fā)環(huán)境， LabVIEW 也是一種通用編程系統(tǒng)，具有各種各樣、功能強(qiáng)大的函數(shù)庫，包括數(shù)據(jù)采集、 GPIB、串行儀器控制、數(shù)據(jù)分析、數(shù)據(jù)顯示及數(shù)據(jù)存儲(chǔ)，甚至還有目前十分熱門的網(wǎng)絡(luò)功能 ， 是一個(gè)功能強(qiáng)大且靈活的軟件 。 目前在這一領(lǐng)域內(nèi)，使用較為廣泛的計(jì)算機(jī)語言是美國 NI 公司的 LabVIEW。s rapid development in electronic measurement and instrument field of application of testing new theories, Virtual instrument has emerged and obtained very big development. Now in this field， Using a wide range of puter language is the NI pany LabVIEW. LabVIEW is a kind of graphical programming language,of the development environment. LabVIEW also is a kind of mon programming system, With various and powerful function, Including data acquisition, GPIB, Serial instrument control, Data analysis, Data display and data storage, Even now very popular work function, Is a powerful and flexible software. 西北師范大學(xué)物理與電子工程學(xué)院 2020 屆畢業(yè)論文 LabVIEW also have simulation and Debugging tools. If set breakpoint and Singlestep etc. The dynamic continuosly, Can continuously and dynamic observations of the data and programs. And with other puter language LabVIEW have a particularly important difference: Other puter language is based on the text of the language code, but LabVIEW using graphical programming language G language.
