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.
