摘要
文章介绍了一种基于ARM微控制器LPC2119和嵌入式实时操作系统μC/OS-Ⅱ的数据采集系统,不仅能够以高速度、可靠、稳定、实时地完成多路模拟量信号以及开关量信号的数据采集,而且能够满足远程和近程数据采集的需要。文中构建了系统的总体设计方案,详细给出了硬件电路设计方法,同时简要说明了移植μC/OS-Ⅱ嵌入式操作系统的关键以及软件设计的要点。
A kind of data acquisition system based on ARM Micro-controller LPC2119 and embedded real-time operating system μ C/OS- Ⅱ is introduced in this essay. The system not only performs the real-time data acquisition of multi analog signal and switch signal with high speed, reliability and steadiness, but also satisfies the needs of remote and close data acquisition. The overall design plan is given in this essay. The hardware circuit design is expounded, and the transplant keys of μ C/OS- Ⅱ embedded operating system and software design keypoints are explained simply.
