本文詳細(xì)的闡述了基于ARM 處理器的數(shù)據(jù)采集系統(tǒng)硬件部分的設(shè)計與實現(xiàn)。整個硬件
電路分成兩個部分：主控電路部分和數(shù)據(jù)采集部分。在主控電路部分，我們完成了主芯片設(shè)計、存儲器電路、串口電路、網(wǎng)絡(luò)電路的設(shè)計。在數(shù)據(jù)采集部分，我們完成了信號調(diào)理電路、濾波器電路、A/D 轉(zhuǎn)換電路、D/A 轉(zhuǎn)換電路的設(shè)計。最后給出了系統(tǒng)硬件調(diào)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.
