使用无线传感器网络设计远程会诊系统

Design of a Long-distance Consultation System Using Wireless Sensor Networks

针对家庭医疗保健工程与医院外特例病人监护,提出了一种基于无线传感器网络的远程交互会诊系统。系统将传感器节点集成为局域网采集人体多种生理信息,通过码分多址无线网络技术将信息上传Internet,送到基于GIS空间定位查询技术的数据库,从而实现电子诊断。用户或管理员可以通过Internet远程访问监测区域。研究结果表明,系统采用设置静态网关和移动探测节点的星型被动式拓扑结构,结合了智能分布式无线传感、计算和无线通信技术,有很大的实用价值。

A remote interactive consultation system based on wireless sensor networks is proposed for family health care works and non-hospital special case patient monitoring.The sensor nodes are integrated into a local area network to collect a variety of human physiological information,which is uploaded to Internet through the Code-Division Multiple Access（CDMA） wireless network technology and sent to the database based on GIS spatial location query technology for achieving electronic diagnosis.Users or administrators can visit remote monitor region through Internet.The results show that the system,using a star passive topology of static gateway and mobile detection node,combines intelligent-distributed wireless sensing,computing and wireless communication technologies.Hence the proposed system has a great practical value.
