【摘要】 设计了基于无线传感器网络(WSNs)的脉搏血氧饱和度中央监护系统;系统利用WSNs的各节点位置随机分布,自组织网络等特性,结合脉搏血氧饱和度监测仪,应用无线的方式完成了病人脉搏血氧饱和度监测的任务;其中一个传感器节点与血氧仪相连进行数据采集;其它的节点组成多跳路由通讯网络,把血氧仪采集到的数据传到中央监控站(host computer)里;最后通过一个友好的图形用户界面来接收和显示所有的监测患者的实时监测数据,并经分析、处理后实现自动报警,自动记录;试验结果表明具有很高的测量精确度,且在设备的实用性、方便性、可管理性等方面有了极大提高。更多还原

【Abstract】 We present the design of a wireless system that can be used to monitor pulse rate and oxygen saturation in the blood,wireless sensor networks each node to spread the feeling position to distribute random,form the organization network by themselves.The information that each node collect carries on the localization processing,work together to complete the data collections,routing,etc.One mote was interfaced to the pulse oximeter for data acquisition and the others were utilized to route the %SpO2 data to the monitoring station.A user-friendly graphical user interface was developed to capture and display incoming measurements for all patients being monitored.Test results indicated high accuracy in the measurements.Moreover,it have a obvious inprovement at practicability、facilities and manageability.更多还原
