一种基于无线传感器网络的远程医疗监护系统

介绍了一种基于无线传感器网络技术的嵌入式远程医疗监护系统．首先，提出了以各种无线通信生理指标传感器形成一种可扩展的无线传感器网络的系统结构．然后，介绍在该系统结构中采用的无线生理指标传感器节点以及监护基站设备的设计．在本系统中，节点和基站设备所使用的近距离通信标准为802.15.4/Zigbee标准，同时本系统中的基站设备可以采用多种接入方式进行远距离数据传输，包括直接联入Internet网络、使用GSM短消息通信方式或者通过modem接入Internet网络．该系统可以应用于家庭以及医院病房，构成远程的家庭、社区以及医院的医疗监护系统．

A Remote Health Care System Based on Wireless Sensor Networks

An embedded remote health care system based on wireless sensor network technology is established. Firstly, a new system architecture is proposed which introduces a scalable wireless sensor network with a variety of wireless physiological sensor nodes. Then the designs of several wireless physiological sensor nodes and the care base-station are presented. Wireless communication between the sensor nodes and the care base-station is realized with IEEE 802.15.4/Zigbee standard, and the care base-station and the remote central server are connected in one of the following ways, including computing network, GSM short messages and telephone modem. The system can be used at home or in hospitals to form a remote health care system among home, community and hospital.
