中文摘要：针对医院外人员远程监护,提出了一种基于无线传感器网络的人体动态生理参数采集系统。系统将传感器网络节点布置于人体相应部位连续采集多种生理信息,直接无线发送到网关,经网关处理后将有价值信息通过CDMA网络上传因特网送至专家系统,实现远程电子全双向的互诊。利用所研制系统对受试者距离监测中心30 km外进行心音采集实验,实验结果与客观相符,实验数据误差不大于0.2%。实验证明,系统稳定地工作在950 MHzISM频段,接收灵敏度-98 dBm,发射功率0.75 mW,数据速率40 kbps,通信距离2.5 km。而且较好地满足了实时远程监测的要求。系统符合人类生活健康质量高要求的趋势,实现了远程医疗资源共享,因此具有特别旺盛生命。

外文摘要：A remote system based on wireless sensor networks is proposed for Non-hospital personnel dynamic monitoring. The corresponding position of sensor nodes are arranged in order to collect a variety of human physiological information,and transported to sink by wireless directly. The information is processed and the valuable information is uploaded to Internet through CDMA network, and sent to the database and achieve electronic full duplex diagnosis. The developed system is used to collect the heart sounds of a volunteer that is over 30 kilometers away. The experimental result is objective. The data error is not more than 0.2 percent. The model experiment shows that the system operates stably at the operating frequency 950 MHz ISM bands, receives sensitivity -98 dBm, transmits power 0. 75 mW, data rate 40 kbps and wireless communication distance 2.5 km. It satisfies the real-time requirement of remote monitoring. The feature of system is the share of medical resources and is suitable to improve human health quality. So it is vital.
