基于LabVIEW的数据采集卡控制和温度采集方法研究

The Research Based Data Acquisition Card Control and Temperature Acquisition Method of LabVIEW

设计了基于数据采集卡和LabVIEW的热电偶温度测量系统框图。实验结果表明该数据采集系统能够准确采集到室温环境的温度数值,并具有操作方便、直观、易于保存、精度较高等特点。

This paper describes the preparation of data acquisition card driver and the implementation of data acquisition in non-NI Co.were conducted by dynamic link library of.dll form.At the same time,it designed the block diagram of thermocouple temperature measurement system based on the data acquisition card and LabVIEW.The experimental results show that the data acquisition system can accurately collect the temperature data of room temperature environment,and has the advantages of convenient operation,intuitive,easy to preserve,more precision.
