物联网的老年人远程监护定位系统

Remote monitoring and positioning system for old people based on Internet of Things

针对老年人独自一人发生意外跌倒以及血压异常等情况,设计了一套基于物联网的远程老年人监护定位系统。该系统采用物联网云平台方式存储和分析数据。结合GPS/北斗进行定位,将便携式终端所采集的心率、血压、跌倒特征及定位等信息通过移动通信模块实现与新浪云的远程无线数据交互,利用移动网络连接到云平台,当检测参数出现异常时,云平台数据库向监护人终端推送报警功能。实验结果表明,该系统能够识别出老年人跌倒行为及血压、心率异常情况,并将识别结果与老年人位置信息发送给监护人,便于监护人及时实施救治,减少老年人独自一人时因跌倒和突发疾病所带来的伤亡风险。

A remote monitoring and positioning system based on the Internet of Things(IoT)is designed for old people when they are alone and have unexpected fall or abnormal blood pressure.The Internet of things cloud platform is used to store and analyse data in this system.Combined with the global positioning system(GPS)/BD positioning,the heart rate,blood pressure,fall characteristics and positioning information are collected by the system terminal realizing the interaction with Sina cloud through the mobile communication module.Thus,the mobile network is connected to the cloud platform.When the detection parameters are abnormal,the alarm function is activated to the guardian terminal in the cloud platform database.Experimental results show that the system can identify the fall behaviour,abnormal blood pressure and heart rate,and send the recognition results and the location information of the elderly to the guardian.The guardian can be informed and implement treatment in time,and thus it reduces the risk of casualties caused by falls and sudden diseases when the elderly are alone.
