And other computer languages main differences are the use of graphical programming language that is G programming language. Advantage of the visual image. With the continuous development of science and technology, more and more extensive applications of virtual instrument. Light intensity is one of important characteristics of light, has an important impact on the surrounding environment, light intensity measurement and control of great significance in many areas, real-time monitoring of light intensity as an important task and an important part of production activities, labor inspection is not only a waste of money, material, and had an error, no longer meet the development needs. Programs written using LabVIEW software to easily achieve the purpose of detecting light intensity. Beijing Di Yang Zheng Tai technology company's LabVIEW experimental system, comes with a data acquisition and signal conversion system. On this basis, the preparation process can improve the light intensity is too high or too low to achieve the system alarm purposes. After testing, the program in environmental light intensity is too high or too low, the warning lights turned on and sent Om song, has a strong role in detection of light intensity, has high practical value.
