DSP控制数据采集仪系统设计

System design of DSP control data collecting instrument

介绍了TMS32 0VC33控制下的地震记录仪的整体设计过程。本系统是采用TMS32 0VC33为主控芯片采集由16位模数转换芯片AD976转换后的 16位数字量 ;经TMS32 0VC33处理后的 16位数字量完成与上位计算机通信。主要应用过采样技术、滤波技术、数字滤波技术、DSP技术、数字信号处理技术等现代电路设计技术 。

This text introduces the whole design process of data collecting system which is controlled DSP in detail.The system mainly adopt DSP’s controlled chip,collecting 16 bits number which is converted by 16 bits analog-to-digital controlled chip named AD976 and the 16 bits number accomplish communicating with last computer after processed by DSP.It has mainly been applied in such as the modern circuit design technology,sampled technology,filter technology,digital filter technology,DSP technology,digital signal processing and so on,which make the system to be a classical production of data collecting.
