摘要
为了提高数据采集系统的开发效率,减少开发成本,以LabVIEW为开发平台,设计了一套数据采集与处理系统.系统以NI-PCI6221作为采集仿真设备,采用模块化和层次化思想,进行了LabVIEW程序设计和界面设计,模拟实验了电压和温度两路信号的数据采集、实时显示、数据存储、数据处理、历史回放功能.实验仿真结果表明,基于LabVIEW的数据采集系统能够有效地实现数据采集以及在线分析处理,此外借助LabVIEW丰富的函数库,易于进行系统功能扩展.
In order to improve the efficiency of data acquisition system and reduce development cost,a data acquisition and processing system was designed based on LabView.The idea of modularization and layering was utilized in this paper,by the use of NI PCI-6221 as a simulator of the data acquiring equipment,dual-channel signal including voltage and the thermocouple temperature,data acquisition,real-time display,data processing,storage and playback can be realized.Simulation results indicated that the data acquisition system based on LabVIEW can effectively implement data acquisition and online analysis.In addition,with the aid of the LabVIEW function library, it＇s easy to extend system function.
