摘　　要：为了实现对模拟量的高速采集与快速傅里叶分析,提出了一种基于FPGA的高速数据采集分析系统的设计方案,系统采用Cyclone系列FPGA配合高速A/D转换器,并使用了Altera公司的定制快速傅里叶分析集成核,通信与上位机采用RS 232串行通信标准协议配合基于Matlab GUI的上位机分析软件,并对多组高频模拟信号进行了高速数据采集与快速傅里叶分析实验,同时在上位机分析软件中实时显示出分析结果。实验结果验证了快速傅里叶分析理论,实现了低成本、高性能数据采集分析系统的设计完成。In order to realize the high-speed acquisition and fast Fourier analysis of analog quantity, a design scheme of high-speed data acquisition and analysis system based on FPGA is proposed in this paper. Cyclone series FPGA chip, highspeed A/D converter and Ahera＇ s fast Fourier analysis integration core are used in the system. RS-232 serial communication standard protocol and host analysis software based on Matlab GUI are adopted for the communication. The high-speed data acquisition and fast Fourier data analysis experiment are employed for multi-group high-frequency analog signal. The analysis result is displayed in real time in the principal computer analysis software. The fast Fourier analysis theory was validated in the experiment. The design of low cost but high performance data acquisition and analysis system was completed.
