基于LabVIEW2012FPGA模式的数据采集和存储系统

摘要

为了提高数据采集系统精度，减少开发成本，提高开发效率，基于LabVIEW虚拟仪器开发工具研究并设计了一种数据采集系统。该系统采用FPGA编程模式和网络流技术实现大批量数据实时传输，并对数据进行分析处理和存储。系统硬件采用美国NI实时控制器CRIO-9025，实现16路数据可靠采集与存储。实验仿真及实际运行结果表明该数据采集系统能够精确地对数据进行实时采集以及分析处理，达到了项目要求。%In order to improve the accuracy of the data acquisition system,reduce development costs and improve develop-ment efficiency,a data acquisition system was designed on the basis of the development tool research for LabVIEW virtual in-struments. The FPGA programming mode and network flow technology are adopted in the system to execute real-time transmis-sion of the mass data,which is analyzed,processed and stored. The real-time controller cRIO-9025 made by National Instru-ments(NI)is used in the system hardwares to achieve 16-channel data acquisition and storage. Simulation and experimental re-sults show that the data acquisition system can realize the accurate real-time data acquisition and analysis,and meet the project requirements.
