摘要
主要介绍ATmega168V为核心的心电信号采集系统的设计与实现,并给出主要硬件电路原理图以及系统软件结构与流程图。系统采用了性能优异的数字滤波器简化硬件电路,以尽可能优化的软、硬件配置完成系统功能,通过设置可直接与PC机或PDA通信,软件可进行远程自动升级,具有结构简单、性能优异和便于扩展等特点。
The paper introduces the design and realization of ECG Signal Sampling System Based on ATmega 168V, and shows the scheme of the main circuit. The frame and flow chart of the software are showed in the paper. To minimize the circuit, the digital filter with good performanceis used. The system can communicate with PC or PDA directly through corresponding setting and the software of system can be upgraded remotely. It has the characteristics of simple circuit, high quality and SO on.
