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.
