The Realization and Application of DAQ System Based on LabVIEW and Serial Port

This paper describes the features of LabVIEW,and introduces the method of data acquisition based on LabVIEW and serial port.By the above method,we complete designing a real-time monitoring vacuum system,which reads the serial data of the vacuum gauge by LabVIEW's VISA,then deals with the data and shows it.This realizes the serial data acquisition of vacuum based on LabVIEW.
