摘　　要：为了适应现代数据采集系统朝着强实时、多参数、高精度方向的发展,以及克服传统单片机数据采集系统无法适应安全性高、实时性强场合的缺点,本文设计了一种基于ARM7处理器核LPC2210和嵌入式实时操作系统μC/OS-Ⅱ的数据采集系统。该系统采用了串口、USB、以太网3种与PC机的通讯方式,以适应不同场合的需要,非常方便。经实测,此嵌入式数据采集系统比传统的数据采集系统具有更高的实时性和稳定性,同时硬件的体积更小、功耗更低、扩展性更强。In order to adapt the situation of modem data acquisition developing with good real-time performance, multiparameter, high precision and overcome the disadvantage of the traditional data acquisition system, this paper designs a kind of data acquisition system based on ARM7 processor LPC2210 and real-time embedded operating system μC / OS-Ⅱ. The system can communicate with computer in series interface, USB and Ethemet in order to adapt different needs,so it is very convenient. This system is safer than the traditional data acquisition system and has a good real- time performance. Meanwhile, the volume of the hardware is smaller, the power consumption is lower, the expansibility is stronger.
