基于LabVIEW的多功能数据采集系统的设计与实现

Design and Implementation of the Multi-functional Data Acquisition System Based on LabVIEW

在数据采集系统中,数据处理的稳定性和多样性十分重要,为了达到数据采集多功能分析的要求,对以LabVIEW为开发平台的采集系统进行了研究。系统对采集数值进行输出计算和对传感器进行零点漂移校正,并对采集数据进行波形回放,对需要的输出波行进行曲线拟合。试验表明,系统能够达到多功能分析的要求,良好的人机交互界面更加方便了实际应用。

In data acquisition system,the stability and diversity of data processing are very important.In order to achieve the requirements of multi-functional analysis of data acquisition,the acquisition system with LabVIEW as the developing platform is researched.In the system,through calculating output of the collected value,and correcting the zero point drift of the sensor,and playing back the waveform of data collected,and doing curve fitting for the output waveform if necessary.The experimental result shows that the system satisfies the requirement of multifunctional analysis,and features good man machine interactive interface,and it is convenient for practical application.
