摘　　要：针对工业控制中实时数据采集的需求,以ARM7处理器LPC2290与嵌入式实时操作系统μC/OS-II为基础,设计开发了基于LPC2290的数据采集终端设备,给出了系统的整体设计方案、结构框图以及基于ARM平台的硬件电路。整个系统硬件体积小、功耗低、扩展性强、运行稳定、程序维护和升级方便,实现了多通道的在线实时数据采集、传输、处理与显示等功能。Aiming at the requirement of real-time data collection in industrial control, based on ARM7 processor LPC2290 and embedded realtime operating system μC/OS-Ⅱ , the LPC2290-based data acquisition terminal has been designed and developed. The general design scheme of the system, structural block diagram, and the ARM platform-based hardware circuit are given. The system is in compact hardware, low power consumption, running stably, easy program maintenance and upgrade. It achieves the functions of multi-channel on-line real-time data acquisition, transmission, processing and display, etc.
