基于穿戴式平台的老人摔倒监测系统设计

摘要

针对老年人跌倒伤害预防问题,基于人体躯域网络可穿戴检测平台,设计了一种人体摔倒生理状态检测系统.系统主要包括摔倒状态检测模块,人体生理状态检测模块,GPS定位模块以及远程监护模块等.当老年人摔倒发生时,摔倒状态检测模块通过三轴加速度传感器检测,确认摔倒后立刻与远程监护平台通信,告知监护人,并通过穿戴式生理状态检测模块实时监测其心率信息,利用GPS定位,通过无线通信的方式将摔倒位置以及生理信息实时反馈给监护人.实验结果表明:该系统可以有效监测老人摔倒状态和生理状态,对及时救助有很大的帮助,具有良好的社会意义.%Aiming at the problems of prevention of elderly tumble damage,a wearable platform based on human area network which detects physiological status when the elderly fall down is designed.It mainly includes fall state detection module,human physiological state detection module,GPS positioning module and the remote monitoring module.When the elderly falls,the fall state detection module detects by triaxial acceleration sensor after confirm falling,the system immediately communicates with remote monitoring platform,transmit message physiological state information and GPS localization information about the elderly to the guardian by the wireless communication.The guardian can succor the elderly in time.The Experimental results show the system is effective for the elderly fall status detection and physiological condition monitoring can help for timely succor,and has good social significance.
