Wireless Human Body ECG Monitoring System Based on Zigbee

摘要:

提出了一种基于Zigbee技术的人体心电信号无线监测系统设计方案；采用Zigbee技术和STM32W108 ARM芯片设计了系统采集节点和汇聚节点的硬件电路,采用C语言编写了其软件,实现人体心电信号的采集和无线传输；利用Labview软件设计人体心电监测界面,实现了利用PC机对采集到的心电信号进行实时监测；实验表明,该监测系统通信质量良好,能够实现心电信号的采集、波形显示,以及心率值和心电频谱的分析,在家庭医疗领域具有较高的应用价值。

Abstract:

This paper presents a ECG monitoring system design based on Zigbee technology; Use Zigbee technology and STM32W108 ARM chip to design the hardware circuits of acquisition nodes and sink node, and use C language to write their software, to realize human ECG acquisition and wireless transmission; Through the PC for data monitoring and analysis based on the ECG monitoring user interface designed by the Labview software of National Instruments Company. The experiments show that, the monitoring network achieves relatively more precise ECG acquisition, monitoring and analysis of heart rate and ECG spectrum. The system has certain application value in the family guardianship field.
