Design and Implementation of Automatic Data Acquisition System Based on ARM

摘要:

为满足环境恶劣、人烟稀少地区数据自动采集的要求,提出并实现了一种基于ARM的全自动数据采集系统的方案；设计的主控板硬件电路以AM3352为核心,配备数字量和模拟量采集模块,扩展以太网、WIFI、RS232/485等外设接口；开发的主控软件在嵌入式Linux操作系统中实现全自动数据采集控制,开发的基于Android的手机APP可与主控软件实时通信,设置采集系统的各项参数；测试结果表明,开发的全自动数据采集系统具有操作方便、采样精度高以及运行稳定等优点,可满足实际应用。

Abstract:

A scheme of automatic data acquisition system based on ARM is proposed and realized to meet the requirements of automatic data acquisition in poor environment and sparsely populated areas；The hardware circuit is designed with AM3352 as the core,equipped with digital and analog data acquisition module,extended with Ethernet、WIFI、RS232/485 interface；The developed software in Linux embedded system can realize automatic data acquisition and control；The developed APP based on Android can communicate with the software in real time and set various parameters to acquisition system；The test results show that the developed automatic data acquisition system which is easy to operate、running stable and provides high sampling accuracy,meets the practical application. 
