摘要
健康监测是无线传感器网络的一个重要的应用方向。本文给出了基于无线传感器网络的心电信号采集系统设计。该系统利用INA118仪表放大器对心电进行放大;采用Jennic公司的JN5139芯片设计微型无线传感节点,网络采用Zigbee协议。系统具有体积小、功耗低,成本低的特点。对人体进行的实测结果表明,系统能够实现实时心电监测。
Health care is an important application of wireless sensor networks(WSN).This paper presents a portable ECG monitoring system based on the technology of WSN.ECG signal is amplified using INA118 instrument amplifier.The wireless sensors board is designed with the use of Jennic s JN5139 chip,and runs the Zigbee protocol.The node has small size,low power consumption and low cost.The experimental results from human testing show that the system can achieve real-time monitoring of ECG.
