Smart Bracelet Design Based On Elderly In The Community

The main research topic of the dissertation lies in the health problems facing the aging population in today's society.The only child is busy with the work and needs to take care of the next generation.The elderly lack care.Based on this,this paper proposes to design and develop a smart bracelet based on the elderly in the community.The community doctors and their family members can control the physical status of the elderly in real time.In the event of an elderly person falling or suffering from illness,the community doctors and their family members can be treated for the first time,effectively avoiding secondary injuries caused by long-term unresponsiveness due to the onset of the elderly,and acting as a "bridge of life" on the health problems of the elderly.Through the analysis of the performance of the smart bracelet in the market,the current smart bracelet lacks the ability of family members to monitor the wearer's physical status information in real time.This article aims to solve this problem by using wireless communication technology and Android software development platform to create an APP to solve the family members can real-time grasp the wearer's physical state information.Based on the smart bracelet system for the elderly,STM32 is used as a hardware development platform,and a photoelectric reflection type heart rate sensor is used to collect heart rate information,and a temperature sensor is used to collect the body surface temperature of the wearer.Six-axis sensor technology is used to achieve the data acquisition of the wearer's movement state of the opponent's ring.Using the STM32F103CBT6 microprocessor,the wearer's movement status,heart rate,body temperature and other data are analyzed,and the display module is driven to achieve data display.At the same time,the wristband data is sent to the cloud server through the GPRS communication module,and the server sends the data to the mobile phone APP application developed based on the Android software development platform,realizing the real-time monitoring of the wristband data of the remote mobile phone.The measurement results show that the wristband system can accurately measure the wearer's heart rate,exercise state,body surface temperature and fall alarm,and use the mobile phone client to know in real time the wearer's physical condition.The tested data has initially reached the expected research target.In the subsequent research work,the system will increase GPS positioning and wireless charging technology to achieve the positioning of smart wristbands and prolong the service life.By further improving and strengthening the function of the smart bracelet,it has a good social significance and application value in solving the health problems facing aging.
