摘　　要：本文主要介绍了基于ARM和GPS的数据采集记录仪中的数据采集模块的设计与实现。该数据采集记录仪以32位ARM7微处理器LPC2220为硬件平台,以uC/OS-II嵌入式实时操作系统为软件环境,实现了对复杂工业信号的采集、记录以及对此过程的控制。该数据采集模块具有4路采集通道,能对信号进行连续采集;同时利用GPS全球定位系统技术实现多仪器间的精确同步。该数据采集记录仪具有良好的人机交互性、稳定性、高效性。It was mainly introduced how to design and realize data acquisition module in this text. The data acquisition recorder can collect, record the complex industrial signals and control this process with the basis of 32 bits ARM7 embedded microprocessor hardware platform and μC/OS-Ⅱ real-time embedded operating system software environment. It has four-way signal acquisition channel that can collect the signal continuously, at the same time, makes the use of GPS which can make it more precise synchronization between instruments. The data acquisition recorder based on ARM and GPS has a good human-computer interaction, and is stable and efficient.
