Abstract:

In the era of deep aging, and the health issues of the elderly population have become a hot topic and focus of social attention. In today's world where heart disease has become one of the biggest threats to human life and health. Developing a low-power dynamic electrocardiogram signal acquisition and monitoring system suitable for home environments is of great significance for timely collection and tracking of electrocardiogram signals and prevention and monitoring of heart disease for home populations. Therefore, this paper designs a low power consumption dynamic ECG monitoring system suitable for home use without amplification. The system uses STM32F1 as the microcontroller, ADS1298 chip as the dedicated ECG signal acquisition chip, Wi Fi technology is wirelessly linked to the Internet, so that real-time collected ECG signals can be transmitted to the cloud server in time. The cloud server uses Labview to achieve signal processing, display, storage and analysis. The experimental results show that the system has low power consumption, small size, stable wireless transmission signal, suitable transmission distance for home scenarios, and can achieve normal monitoring and analysis of home electrocardiogram signals.
