Design of Portable ECG Monitor Based on Embedded Technology

介绍一种基于嵌入式技术的心电监护仪的设计与实现方法,它具有实时采集、显示、心电信号自动分析处理、报警等功能。系统以基于ARM9内核的32位低功耗微处理器作为控制核心,在心电信号处理中应用了50Hz滤波及合适的R波检测等算法。该系统具有良好的可靠性和精确性,且操作简单,体积小,方便携带,很适合家庭和个人的需要,可作为医生对病人诊断、治疗、观察监护的辅助性设备。

This paper introduces the design and implementation methods for a kind of portable ECG monitor based on embedded technology. It has functions of real-time data acquisition, display, automatic processing for ECG signals and alarm etc. It selects 32 bit microprocessor of low power consumption, which is based on ARMg, as the core of the system. For ECG signals processing, it applies a filter at 50 Hz and suitable detection algorithm for R wave. The system has good reliability and accuracy. It meets the needs of families and the individuals with the features of simple operation, small size and easy to carry etc. It will be used as a good auxiliary equipment of diagnosis, treatment and monitoring for doctors.
