多通道高速数据采集系统的设计与实现

摘要

Multi-channle and high-speed data acquisition system of USB based on LabVIEW was designed to solve the practical data acquisition problems, it was mainly composed of CY7C68013 ,MAX1320 and FPGA in the system to meet the needs of the multi-channel and high speed data acquisition. Besides,to store the multi-channel data,to display and to analyze the data were a-chieved with multi-thread mechanism on the basis of LabVIEW. According to the pratieal applications, The system works well and the acquisition data is correct and reliable.%为了解决多通道数据的高速采集问题,文中讨论了一种基于LabVIEW平台的USB多通道高速数据采集系统的设计方案.该系统采用了USB芯片CY7C68013和A/D转换芯片MAX1320并配合FPGA技术实现多通道数据的高速同步采集,同时基于LabVIEW开发平台采用多线程技术实现了对多通道采集数据的文件存储、显示和分析.经调试应用证明,该系统运行稳定,数据采集可靠实时.
