Abstract
With the rapid development of computer technology and virtual instrument technology,virtual instrument is being regarded as the developing trend for the development of measuring field. This text introduces an important method of driving normal DAQ board under the LabVIEW—DLL and the key technique and step in LabVIEW that make use of Call Library Function Node to call DLL. Carrying out the coalescent of LabVIEW and normal DAQ board. Enrich LabVIEW' s control to hardware. Then carry out the save and manage automatically of data through building the Access database. Expanding the function of virtual test system.
