摘要
采用基于软件体系结构的虚拟仪器技术构建的数据采集系统具有资源的可重复利用率高,系统组建时间短,功能易于扩展,维护和开发的费用低及远程数据采集功能等优势。以LabVIEW 7.1为开发平台,NI-6221 DAQ卡为数据采集硬件,将虚拟仪器前面板与传统仪器面板对应,构建了基于虚拟仪器技术的数据采集系统,实现了常用虚拟信号分析处理实验仪器。
The Data Acquisition System of virtual instrument has advantages of higher reusable rate,short design period,easily extended function,fewer expensive,remote and so on. In this paper,the design of DAS by using LabVIEW 7.1 and NI-6221 DAQ is presented,According with the front panel of conventional instrument,common signal analysis processing instrument is developed.
