基于无线传感网的老人监护系统

通过对老人监护问题的需求分析,设计一套基于无线传感网的监护系统。本系统设计了便携式的心电检测仪,实时采集被监护对象的心电信号,并采用嵌入式零树小波变换算法实现心电数据压缩;同时,构建无线传感网络,利用基于RSSI的三点定位算法实现对被监护对象的定位。最后,将心电数据和位置信息通过无线路由传至监护中心的终端软件,供分析、显示和记录。实验表明,该系统能较好地完成心电信号检测及定位功能,有助于医疗人员实施老人监护工作。

Elder Monitoring System Based on Wireless Sensor Networks

A monitoring system based on wireless sensor network is designed in order to solve the problem of elder monitoring.This project has designed a wearable ECG monitoring module to collect the real-time data of ECG signal,and uses the Embedded Zero tree Wavelet ECG compression algorithm to compress the ECG data.It builds a distributed wireless sensor network,and uses the three points location algorithm to achieve the positioning tasks of the elders.Then the system sends the physiological data and the location message to the software on monitoring center to analyze,display and record.The routing line is selected through analyzing the calculated results.The experimental results show that this system performances excellently in ECG tests and positioning tasks of the elders.Therefore,it contributes to the monitoring of elder,and meets the demand of aging.
