中文摘要:
      介绍了一种基于DSP的高速数据采集处理系统的设计及其关键技术。系统使用高速A/D和CPLD实现了采样率为40 Msps的高速数据采集,然后将采集到的数据送到DSP进行处理,实现了去直流处理、参数测量、数字滤波、信号抽取和插值、频谱分析等功能。通过按键操作,将处理后的波形图和参数用液晶屏显示,可以实现数据采集波形、相位谱、功率谱等显示。系统的测试结果表明:系统实现了研究的预期目标,可进一步开发为高速的多功能虚拟仪器,对后续的研究工作有一定的借鉴意义。系统人机界面友好,操作简便。
英文摘要:
      This paper introduces the design and key technology of a high-speed data acquisition and processing system based on DSP. The system realizes high-speed data acquisition of 40 Msps by high-speed A/D and CPLD, and sent the data to DSP for processing. It can realize the functions of DC removal, parameter measurement, digital filter, signal sampling and interpolation, spectrum analysis. Through key operation, the system display processed waveform and parameters with LCD screen, and can display data acquisition waveform, phase spectrum, and power spectrum. The test results of system show that the system has realized the anticipated goal of study. The system can be further developed as a high speed multi function virtual instrument. The research results have certain reference significance for the follow-up research work. The man-machine interface is friendly and the operation is simple.
