| 摘 要： | 设计了一种以DSP(数字信号处理器)为核心处理模块的数据采集系统,用于采集和处理两路传感器获得的信号。系统采用高速A/D转换器和DSP芯片,并结合相关算法软件,实现了实时的信号处理功能,结果可以经D/A转换后输出或以其他方式输出。实测表明,该系统工作稳定,只需根据采集信号种类的不同及输出要求的不同设计相关的算法软件,即可在工业生产过程或仪器仪表中使用该系统。

| Abstract: | Designed a kind of data acquisition system take DSP as the core processing module, in order to gather and process the signals which two sensors obtain. Because the system uses the high speed a/d switch and the DSP chip, the real-time signal processing function may be realized, combining the correlative software algorithm with it. The results may be output after A/D transformation or by other forms. Actual measuring indicated that this system worked stable. Only through design the correlative algorithm software according to different types of the gathered signals and the output requests, this system can be used in the industrial production process or the instruments and meters. |
