题目：基于ARM的多路数据采集系统设计

摘要

数据采集系统用于将模拟信号转换为计算机可以识别的数字信号.该系统目的是便于对某些物理量进行监视.数据采集系统的好坏取决于他的精度和速度.设计时,应在保证精度的情况下尽可能的提高速度以满足实时采样、实时处理、实时控制的要求.在科学研究中应用该系统可以获得大量动态;是研究瞬间物理过程的重要手段;亦是获取科学奥秘的重要手段之一.

本次设计是基于ARM的多路数据采集系统，主控器能够对模拟信号产生的各路数据，通过数据采集系统进行采集并在主控器的程控下显示。

关键字：数据采集；模数转换；ARM；实时采样。

Abstract

Data acquisition system for digital signal to analog signal conversion can be identified by computer. The system is aimed at facilitating monitoring of some physical quantity. Data acquisition system is good or bad depends on the precision and speed. When the design, should be in the case of ensuring accuracy as much as possible to meet the high speed real-time sampling, real-time processing, the requirement of real time control. The application of this system in scientific research can obtain a large number of dynamic; is an important means to study the instantaneous physical process; and it is also one of the important means of access to the mysteries of Science.

Keywords: data acquisition; ARM; real-time sampling analog-to-digital conversion.
