Design And Implementation Of Home Health Management System Based On Android Platform

With the improvement of science and technology and the continuous progress of society,people pay more attention to family health and safety while they are busy with their work.Especially,children and the elderly,two vulnerable groups among family members,need the most attention.To solve the problem of family health and safety management,this paper designs a family health management system based on Android platform.The family health management system is based on the Android operating system,use the Java language,and use the important components in the Android platform to develop.The system is divided into the Android client and the server.The Android client mainly realizes the user login,heart rate monitoring,motion meter,family member location information display and other functions.The server mainly realizes the data persistence storage and client information interaction and other functions.The family health management system can effectively help users to check the real-time location of children and the elderly in the family and prevent the occurrence of loss.Functions such as heart rate monitoring and pedometer can help users understand their own health conditions and play a certain role in the prevention of diseases.Compared with the products in the market that use wearable devices and client APP for health management,this system only needs to carry smart phone devices,which greatly facilitates the use of users and reduces the cost of users,and can meet the needs of users.The main contents of this paper are as follows:(1)Heart rate collection at the mobile end based on photoelectric volumetric pulse wave technology,fingertip picture stream is collected by the rear camera of smart phone,and slight changes in red depth of picture stream are obtained through YUV format conversion.Heart rate detection algorithm is used to obtain the user's heart rate value.(2)Through the acceleration sensor carried by the smart phone,the user's threeaxis coordinate data is obtained,and the threshold value is obtained through the processing of the data with the kinemometer step algorithm,so as to judge whether the user is in the walking state.(3)By accessing AMap location SDK,display the map in the client APP,and interact with the server to get the corresponding location information through the account association of family members,so as to realize the location view of family members.At the end of this paper,the system is tested by functional test and stress test.The test results show that the system conforms to the expected function and has good social significance and Application value in family health management.
