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.
