本文詳細的闡述了基于ARM 處理器的數據采集系統硬件部分的設計與實現。整個硬件
電路分成兩個部分：主控電路部分和數據采集部分。在主控電路部分，我們完成了主芯片設計、存儲器電路、串口電路、網絡電路的設計。在數據采集部分，我們完成了信號調理電路、濾波器電路、A/D 轉換電路、D/A 轉換電路的設計。最后給出了系統硬件調試方法。

Hardware Design of Data Acquisition System based on ARM Processor WANG Xiao-rong, HE Xiao-song, ZHU Yong-rong (Chongqing University, Chongqing 400030; Chongqing Technological Institute, Chongqing, 401331) Abstract: The hardware design and implementation of an embedded network multichannel data acquisition are described in this paper. The hardware circuit is consisting of two parts: master control circuit and data acquisition circuit. In the first part, it concludes master controller design, memory circuit, serial port circuit, and network circuit; in the second part, the signal modifying circuit, filter circuit, A/D and D/A transfer circuit are designed. At last, the hardware debug strategy of the system is introduced.
