Design And Implementation Of Community-based Aged Care Service System Based On Android

With the rapid development of Internet technology,mobile intelligent terminals play an important role in people's daily lives.By the end of 2018,China's mobile intelligent terminals had reached 1.51 billion,of which Android system accounted for about 83.6%.The development of mobile intelligent terminals and Android software provides people with a more convenient,fast and smooth life.At the same time,China has entered an aging society.There is a lot of pressure on social pensions,and traditional services for the elderly and the way of providing for the elderly face challenges.In the future,the old-age welfare system will be community-centric.Combining community elderly care with the Internet can more rationally manage and utilize old-age resources,and undertake some social pension pressures,satisfying the needs of the elderly and promoting the development of the old-age industry.However,the existing community elderly care service system is relatively repetitive and simple,and cannot meet the comprehensive and personalized elderly care needs of the elderly.Therefore,it is of great significance to develop a community elderly care service system that can meet the needs of the elderly based on the Android system.In view of the application scenario of the aged care service,this paper studies the related technologies of Android,not only studies the view drawing process and event distribution mechanism of Android,but also uses the method and the underlying design principle of the Retrofit2.0 network communication framework and the Glide image loading framework.In addition,this paper investigates the application of community pension services in the Android market at home and abroad,and summarizes the functions,implementation methods and existing problems ofthese applications.On this basis,the user requirements,functional requirements and non-functional requirementsof the system are analyzed,and the system design is determined,including the overall system architecture design,client design,server design and database design.According to the above research content,this thesis designs and implements a community pension service system based on C/S architecture,including Android client and background server.The Android client is available to users,including health care services,health management,smart recommendation,and security management.Among them,the health care module realizes the date and department screening function through the custom control,and the smart recommendation module recommends the appropriate old-age service for the user through the customized recommendation algorithm.The background server is used by managers,including user management,visit management,care management,and care dispatch.The server built the FastDFS distributed file system to ensure the efficient storage of user check reports and the use of Nginx reverse proxy server to improve the system's high concurrency performance.Finally,the pension system was tested by JMeter server test,client function test and Monkey stress test to verify the stability of the application.In response to the growing burden of Chinese society,this paper studies the related Android application technology,and designs and implements an Android-based community care service system.After logging in to the client,the elderly can choose doctors and caregivers for offline health care,and can view and manage the inspection report.The system will recommend personalized care services based on the characteristics of the elderly.In times of crisis,you can call your family and medical staff urgently through a one-button alarm.The system satisfies the comprehensive personalization needs of the elderly in the community,achieves the expected design effect,and has certain practical value.
