如今在測控領(lǐng)域用于開發(fā)軟件系統(tǒng)的開發(fā)平臺主要有：LabVIEW、C++、VB、Agilent VEE、LabWindows/CVI。而LabWindows/CVI由于提供了豐富的函數(shù)庫和各種方便功能得到了不少使用者的青睞。LabWindows/CVI是National Instrument公司開發(fā)的一種基于ANSI C的開發(fā)平臺，它集成了編譯器、連接器和高級編輯、調(diào)試工具。內(nèi)建強大的儀器庫，從儀器控制、數(shù)據(jù)采集到數(shù)據(jù)分析和圖像顯示。LabWindows/CVI自帶代碼生成、交互式函數(shù)面板、函數(shù)提示、快速控件查找等功能，可以幫助開發(fā)者進行快速開發(fā)。
風(fēng)洞數(shù)據(jù)采集主要包括壓力、溫度、天平等信號。
