Research On The Smart Elderly Care System Based On The Internet Of Things

According to survey data,since the 21 st century,the proportion of the elderly population in China has increased year by year.At the same time,most young people prefer to find employment in large cities,leading to the increasingly serious social phenomenon of "children are not around,the elderly are alone in empty nests".Elderly people living alone must not only face all life problems alone,but also suffer from the loneliness and helplessness brought about by unaccompanied people.The community home care model is currently the most suitable for my country’s basic national conditions.It not only caters to the desire of most elderly people to stay in a familiar environment,but also provides help for the elderly in life.At the same time,the rise of the Internet of Things technology has also provided a new development direction for the field of old-age care.Designing a intelligent pension system that meets the diverse needs of old-age home-based old-age care can effectively alleviate the current severe old-age care situation in my country.In this project,a intelligent home care system for elderly people living alone is designed by research,so that the elderly can not only live in their familiar environment,but also enjoy professional elderly care services.This topic first collects and sorts out the relevant literature and materials,and investigates and elaborates the research status and background of the research on the intelligent pension system at home and abroad.Secondly,the overall structure,functional requirements and non-functional requirements of the intelligent pension system are introduced.Thirdly,the four functional modules of telemedicine,intelligent housekeeping,fall detection and health file management in the intelligent pension system were analyzed in detail.Finally,mention the areas that need to be improved in the intelligent elder care system at this stage and the future development trends.The design of the hardware part of this subject focuses on the information collection device of the fall detection module.The development and design of the information collection device of the fall detection module is realized by using the microcontroller technology,and the information collection device that has been developed and passed the test is fixed on the waist of the human body.Realize real-time monitoring and alarm of human falling behavior.Use the MPU6050 sensor to collect human acceleration information and attitude angle information,and output it to the main control chip STM32L151C8T6,set the multi-level threshold algorithm in the main control chip to realize the fall behavior recognition,in order to improve the accuracy of the human fall monitoring method based on the multi-level threshold method Degree,using the SVM algorithm to train feature thresholds.If it is judged that a fall occurs,the Bluetooth module HM-11 communicates with the mobile phone and issues an alarm message.This topic mainly uses Android technology and Java technology to complete the development and design of the system software part,deploy the developed and tested system to the Web network platform,mobile terminal APP and family pension controller,use the MySQL database to store system user information,and deploy the entire intelligent pension system to the elderly community.The staff of the community service station assumes the role of system administrator.Merchants and doctors who have been strictly screened by the community serve as the system’s service provider.The elderly users only need to order through the mobile terminal to send the demand information to the system.The system will The order information of the old man is forwarded to the client of the service provider,so that the service provider can implement the service.Taking into account the fact that the elderly have poor eyesight,poor hand-eye control,and a small display interface on the mobile phone,the family pension controller uses a tablet computer on the Android platform,which can achieve the same function of the mobile phone,so that these problems have been solved well.This topic implements a more practical intelligent elderly care system on the functional level,so that the elderly’s elderly care needs can be responded to in a timely manner,improving the elderly’s elderly care experience,and at the same time making the management staff’s work more systematic and efficient.With the continuous development of computer technology and Internet of Things technology,Intelligent pension system will inevitably play a greater role in the future pension.
