| 摘 要： | 介绍了以数字信号处理器(DSP)为核心的基于PC I总线的高速数据采集与处理系统。该系统采用DSP内部的A/D转换器对高频信号进行采集,用小波分析法对数据进行预处理与分析,通过PC I总线进行主、从机间的数据通信。研究了高速数据采集卡的硬件组成和软件设计,分析了PC I接口的设计。实验证明,该系统能够完成继电器触头分断时过电压信号的采集、处理与快速传输。

| Abstract: | A high speed data acquisition system with DSP as core based on PCI bus was introduced.The system adopts A/D converter in DSP to collect high frequency signal. It uses wavelet method to preprocess and analyze the data collected.It transfers the data processed between PC and DSP through PCI bus.The design of hardware,software and PCI interface were researched and analyzed in detail.The experiment has proved that this system can finish collecting and processing the over-voltage signal,and transferring data processed to PC quickly. |
