Design of Real-time Data Acquisition System Based on ARM Cortex-M3 and Internet

设计一种基于ARM Cortex-M3和Internet的实时数据采集系统。系统选用STM32F107VCT6作为核心芯片,通过链接网络芯片DM9161A,配合程序中采用的嵌入式TCP/IP协议栈LwIP,将采集到的区域温度和电压数据实时传送到远程监测端。实验及测试证明,系统运行稳定,数据采集和传送准确,实时性能良好。

This paper designs a real-time data acquisition system based on ARM Cortex-M3 and Internet.The system select STM32F107VCT6 as the core chip,via linking the network chip DM9161A,cooperating with the embedded TCP/IP protocol stack LwlP which is used in the program.The system can transmit the acquisited area temperature and voltage data to the remote monitoring.
