隨著位移測(cè)試系統(tǒng)日益復(fù)雜的發(fā)展和虛擬儀器的應(yīng)用擴(kuò)大化，文中以虛擬儀器作為技術(shù)平臺(tái)，利用LabVIEW 軟件編寫程序，設(shè)計(jì)液壓系統(tǒng)位移測(cè)試系統(tǒng)。介紹測(cè)試系統(tǒng)的硬件組成及設(shè)計(jì)過程，給出其編寫的程序框圖和直觀的前面板圖，系統(tǒng)具有很強(qiáng)的可擴(kuò)展性，該測(cè)試系統(tǒng)可以實(shí)現(xiàn)位移信號(hào)的數(shù)據(jù)采集、傳送、存儲(chǔ)、調(diào)用、分析和顯示。并且通過現(xiàn)場(chǎng)試驗(yàn)表明此系統(tǒng)具有較強(qiáng)的實(shí)用性、可靠性和操作方便。能夠滿足教學(xué)、工業(yè)的需要。

　　Abstract:

　　With increasingly complex development of displacement test system and the enlargement application of virtual instrument， the paper based on the virtual instrument technology platform， using LabVIEW software to write program for design displacement test systems of hydraulic system.Introducing the hardware form and design process of test systems， and giving its program diagram and intuitive front panel figure， the system has strong scalability， this testing system can realize displacement signal of data acquisition， transmit， storage， calls， analysis and display. And through the field test shows that this system has strong practicability， reliability and convenient operation.It can meet the need of education， industry.
