【Abstract】 In order to simplify the measuring process and improve the efficiency, a design method of the virtual instrument software is introduced in this paper, which uses an industrial control computer as kernel, controlling the existing equipments by software. This system uses the design method of component object model (COM), which makes the software serviced and updated very easily. This system also uses the Access database, introducing the idea of "real-time measuring savings". The whole system doesn’t increase much cost, but achieves the anticipated aims very well.更多还原
