The Design And Realization Of Health Monitoring And Tracking System For Elderly

With the progress and development of human society,people are increasingly concerned about the healthy living conditions of the "weaker groups",such as the elderly,children and the psychos,whose lives have more potential risks and are more vulnerable to accidents.These people,especially the elderly,are suffering from a decline in their physical functions and abilities,which cause a variety of unpredictable problems in their health.Moreover,it is difficult to locate the elderly and rescue in time when emergencies occur.Therefore,aiming at the problems such as the difficulty of real-time monitoring of the health of the elderly and the inability to locate the elderly in real time,this paper designs a system of real-time monitoring and location tracking of the health information of the elderly.The system can monitor the oxygen saturation,heart rate,fall status and geographical location of the elderly in real time.When the elderly need help,it also can find the elderly as quickly as possible and offer help timely.The main work of this paper includes the following points:(1)This paper analyzes the design demands and functions of the system,and proposes the overall design scheme of the system,including the overall design of the hardware,the scheme of oxygen saturation,heart rate and fall detection,the design of the indoor positioning architecture and the outdoor positioning architecture.The detection of oxygen saturation and heart rate uses PPG technology.The acceleration change characteristic and UWB technology are used to detect falling.Indoor positioning detection accomplishes by using UWB positioning technology and outdoor positioning by using GPS + GSM network positioning technology.(2)According to the overall hardware design of the system,the hardware circuit designs of each module in the system are introduced in detail,containing the hardware design of tag node,anchor node and embedded server.(3)Based on the hardware design,we have designed the main programs of tag node,anchor node and embedded server.Besides,the key modules in the system covering oxygen saturation and heart rate detection,fall detection,indoor positioning and outdoor positioning have been analyzed in detail and the software has been designed.(4)Finally,we test and analyze the functional modules of the system to verify it's feasibility and accuracy.Through theoretical analysis and experimental testing,this paper proves that the design scheme of real-time health monitoring and location tracking system for the elderly is reasonable and practicable,which can monitor the health status of the elderly and track the location in real time.
