基于ZigBee和Android技术的独居老人远程监护系统的设计

摘要

In the paper, the chips CC2530 of TI (Texas Instruments) are used to configure wireless sensor networks, by which a remote health monitoring system, interconnected by using ZigBee technology, is developed for elderly people living alone. The system applies a development board named RT5350 as a gateway for aggregating sensing data of body temperature, collecting humidity data of their living environment, and transmitting early warning SMS (short message) about hazardous gases such as carbon monoxide to handheld terminals. A specific detection algorithm, which is used to detect accidental fall of elderly people, is embedded in the sensor, and timely feedback the alarm information to the guardian of the Android mobile terminal. Experimental data show that the system can effectively monitor the health parameters of elderly people living alone and timely warning information of abnormal situation.%本文使用TI公司的CC2530芯片构建无线传感器网络,基于ZigBee技术开发一种面向独居老人的远程健康监护系统.该系统利用RT5350开发板设计网关,采集独居老人体温数据和环境温湿度数据,预警一氧化碳等危险气体.通过在传感器中植入跌倒检测算法,用于判断老人摔倒行为,及时反馈报警信息到监护人的Android手机移动端.实验数据表明该系统能够有效监测独居老人健康参数并及时推送异常情况的报警信息.
