摘要
 
 在這個(gè)信息、技術(shù)日新月異的時(shí)代，利用計(jì)算機(jī)和網(wǎng)絡(luò)等技術(shù)對(duì)傳統(tǒng)產(chǎn)業(yè)進(jìn)行改造已是大勢(shì)所趨。光強(qiáng)檢測(cè)在物理實(shí)驗(yàn)中占有很重要的地位,而且在食品生產(chǎn)、機(jī)械化等領(lǐng)域中也得到了越來越廣泛的應(yīng)用。基于LabVIEW的光強(qiáng)檢測(cè)系統(tǒng)將網(wǎng)絡(luò)技術(shù)引入測(cè)試領(lǐng)域,不僅是虛擬儀器發(fā)展的必然,也是很多測(cè)試任務(wù)的要求
 LabVIEW面向測(cè)試工程師，具有開發(fā)簡(jiǎn)便，技術(shù)集成化高，性能擴(kuò)充性好，自動(dòng)化程度高及系統(tǒng)成本低等優(yōu)點(diǎn)。通過網(wǎng)絡(luò)化虛擬儀器,人們不僅可以共享測(cè)量數(shù)據(jù),而且可以構(gòu)建網(wǎng)絡(luò)化測(cè)試系統(tǒng),從而可以在更大范圍內(nèi)提高人們的測(cè)試效率。
 本文介紹了LabVIEW的概念、產(chǎn)生、發(fā)展及應(yīng)用。對(duì)光強(qiáng)檢測(cè)系統(tǒng)進(jìn)行模塊化分析，其中，重點(diǎn)介紹了與課題實(shí)現(xiàn)相關(guān)的光敏電阻的特性，曲線擬合，光強(qiáng)檢測(cè)系統(tǒng)前面板程序設(shè)計(jì)與實(shí)現(xiàn)。

ABSTRACT

 In this rapidly changing era of information and technology, computer and network technologies to transform traditional industries is the trend of the times. The Detection System of light intensity occupies a very important position in the physical experiment, and also got a more and more extensive application in the realms, such as food production and mechanization...etc. The Detection System of light intensity which according to LabVIEW leads the network technique into the test realm, Not only is the inevitable development of virtual instruments, but also is the requests of plenty of test missions.
 LabView faces Test Engineers, the advantage is easy to develop, the technique integration turns high, the function enlargement is good, the automation degree is high and the system cost is low...etc. Turn virtual instrument through the network, people can not only share the diagraph data, but also set up the network to turn the test system, can raise people's test efficiency in a larger scope thus.
 This text introduced LabVIEW concept, creation, development and applications. It carry on the mold piece to turn analysis with, the point introduced to carry out the characteristic of the related CDS with topic, curve fitting, front panel program of the Detection System of the light intensity design and realization.
