基于ARM的数据采集系统硬件部分实现

本文详细的阐述了基于ARM 处理器的数据采集系统硬件部分的设计与实现。整个硬件
电路分成两个部分：主控电路部分和数据采集部分。在主控电路部分，我们完成了主芯片设计、存储器电路、串口电路、网络电路的设计。在数据采集部分，我们完成了信号调理电路、滤波器电路、A/D 转换电路、D/A 转换电路的设计。最后给出了系统硬件调试方法。

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.
