摘 要

随着科技的进步和人口老龄化的发展，市场上迫切需求一种具备低成本、较高可靠性的无线健康监护设备，用以解决医疗资源短缺和医疗服务不断增加所导致的压力。无线传感器网络低功耗、低成本、方便携带等特点逐渐受到人们关注。近年来我国许多研究机构也逐步提出或实现了许多远程无线监护系统，但是它们大多依赖现有的电话网络或者是卫星网络，使用成本较高，不适合个人应用。本文比较了几种主流的无线通信技术，采用ZigBee协议作为通信协议系统。提出了一种无线健康监测系统，具有多参数，便于携带，具有成本低，功耗低、兼容性强等特点。

Abstract: With the development of science and technology progress and the aging of the population, the market urgently needs a kind of low cost, high reliabilitywireless health monitoring equipment, to solve the shortage of medical resources and medical services with the increase in pressure. Wireless sensor networks are characterized by low power consumption, low cost, convenientportability gradually attention.In recent years, many research institutions in China also gradually presented or implement a lot of remote wireless monitoring system, but most of them rely on existing telephone network or satellite network, the use of high cost, not suitable for personal use.This paper compared several mainstream wireless communication technology,decided to adopt Zigbee as the communication protocol system. And proposes a wireless health monitoring system with personalized, has the features of multi parameter, portability, low cost, low power consumption and strong compatibility.

Keywords: ZigBee; remote health monitoring; Wireless Sensor Networks
