在康复中心或老年公寓中,需要密切关注老年人的健康状况.作为人体最重要健康指标的心电信号,常被作为健康监护系统的首选检测对象.本文设计了一种以MSP430微处理器及CC2420无线模块为核心的ZigBee低功耗网络节点.前端ECG信号采集部分采用了单导联系统,经放大、处理后由单片机进行AD转换,经无线网络上传至PC机后滤除信号中的噪声,以提高心电信号的质量.由此组成网状网络拓扑结构的无线心电信号监护系统能够实现可移动监护对象实时健康状况的检测.

In rehabilitation center or senile apartment, the health status of the elderly need to be taken careful care of. As the most important health indicator of human body, ECG often acts as the first choice detector. The paper designed a ZigBee low-power network node with MSP430 microcontroller and CC2420 wireless module as the core. The ECG signal acquisition uses a two-electrode single-lead system. After being filtered, amplified and other processes, ECG completed the AD conversion by the microcontroller. Then noise is filtered out after the ECG was uploaded to PC by wireless module in order to improve the quality of the signal. The mesh network topology wireless ECG monitoring system composed of the network nodes can realize the detection of movable monitoring objects real-time health status.
