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。
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 embed- ded system can realize automatic data acquisition and control; The developed APP based on Android can communicate with the software in re al 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.
