| Abstract: | By use of virtual instruments LabVIEW software,and rich software and hardware of computer as a platform,the data acquisition circuit is designed,which includes A/D converter module,selection module and channel gain input module.The underlying performance functions and DLL dynamic link library are developed by using LabWindows/CVI and Visual C＋＋ software.In order to achieve starting,selecting,measuring,and other display functions,a new type of digital DC voltmeter design is completed finally by calling the library functions in LabVIEW.Experimental tests showed that the design and development of virtual DC voltmeter has convenient test,high accuracy,small relative error and other advantages.Thus the market prospect is broad. |
