Abstract：In this paper the experiment System for The course of computer control are introduced. The experiment system is made up of control object, test instrument, connection board, date gather card and computer. The experiment system software based on LabVIEW7.0 and PCL -818L is devoleped. The new modularization system based on the platform of virtual instrument is established. A good teaching effect has been brought after the experiment system for the course of computer control had been applied.
