With traditional instruments, the virtual instrument technology means that?on the general-purpose computer platform which contains data acquisition device, according to needs, you can construct various measurement system efficiently. For most users, the main work is a software design. LabVIEW is a programming language based graphical of virtual instrument software development tools, this paper expounds LabVIEW graphical programming language used to develop virtual design of the digital filter process. Silicon pv changes the optical signal into the electronic signa1．The analogy voltage is changed to digital one by the A／D(analog to digita1)converter.Then sent the collected digital signal to the virtual illuminance meter for operational treatment display. By displaying the voltage and the corresponding data collected by calibrated standard illumination, go through the least square method linear fit two sets of data, Values ??by fitting an anti-seeking illumination illumination to achieve the purpose of measurement. 朗读 显示对应的拉丁字符的拼音 KEY WORDS:?
