基于 labVIEW 的数据采集和存储系统

摘要

To improve the accuracy of the data acquisition system,by using LabVIEW virtual instrument,this paper studies and designs a data acquisition system,which uses FPGA mode and network stream technology to realize real-time transmission of large masses of data, and can perform such functions as data acquisition,data storage,waveform display in different forms,monitoring data and alarm.The result of actual operation shows that the system data acquisition process is stable and reliable,and can satisfy design requirements.%为了提高数据采集系统的精确性，采用虚拟仪器 LabVIEW 开发工具研究并设计了一套数据采集系统。采用 FPGA 模式和网络流技术实现大批量数据实时传输，能够实现数据的采集、数据的保存、各种波形显示，监测数据，报警等功能。实际运行表明，数据采集过程稳定、可靠，达到了设计要求。
