Abstract

In order to provide an auxiliary teaching method for comprehensive experimental teaching ofMeasuring Tech nology and Instrumentscourse and greatly improve experiment teaching quality,a virtual data acquisition system based on Lab VIEW and Proteus is presented.AT89C51 in Proteus is used as the slave computer to achieve the functions of data acquisition,data display and data transmission to the host computer.LabVIEW was employed to construct the master system to acquire realtime data from the slave computer,to save and process these data,and to playback them if necessary.The master system com municated with the slave computer by a pair of virtual serial ports constructed by Virtual Serial Port Driver 6.0.Simulation re sults show the virtual data acquisition system has the same operation characteristic as the real hardware system.
