摘要：

背景：针对传统心电监护系统操作不便，成本较高，功耗较大的缺点，研制基于ARM9和嵌入式Linux操作系统的心电监护系统。
目的：设计基于ARM9和嵌入式Linux操作系统的心电监护系统硬件、软件平台。
方法：硬件平台方面，采用S3C2440处理器作为处理器，采用AD620作为信号采集放大模块，利用S3C2440内部集成的CMOS模数转换器实现A/D转换功能，人机交互界面采用TFT液晶触摸屏。软件方面，移植Linux操作系统并对心电信号按Mallat算法进行小波变换，实现QRS波识别。
结果与结论：基于S3C2440和嵌入式Linux操作系统的心电监护系统，能够有效地降低成本，减小设备体积。良好的人机交互界面简单易学，能满足日常家庭使用需要。

Abstract:

BACKGROUND: The traditional electrocardiogram (ECG) monitoring system had many defects such as inconvenient operation, high cost and power consumption, a new EGG monitoring system based on ARM9 and embedded Linux operating system was designed.
OBJECTIVE: To design the hardware and software platform of ECG monitoring system that based on ARM9 and embedded Linux operating system.
METHODS: For the hardware, S3C2440 was used as the microcontroller. The system adopted AD620 as the amplified signal acquisition module. The use of S3C2440 integrated in ADC CMOS achieves internal A/D conversion function; man-machine interface was TFT LCD touch screen. As for the software, operating system borrowed from Linux transforms ECG algorithm by Mallat in order to achieve QRS wave detection.
RESULTS AND CONCLUSION: ECG monitoring system that based on S3C2440 and embedded Linux operating system can effectively cut costs, reduce equipment volume, furthermore, man-machine interface is easy to learn. The new ECG monitoring system will meet the needs of daily use.
