The Design And Implementation Of Health Monitor Application Based On Android

With the spread of smartphones and the rapid development of Bluetooth related Internet of things,intelligent medical care has become the focus of attention and research focus.Based on the Android platform,this paper develops an App that can monitor human blood pressure,blood glucose,and many other vital signs,It stores and analyzes historical data measured by users.The app make people can easily monitor their own health,help people prevent and treat chronic diseases,has application value and significance.First of all,this paper analyzes the research status of smart mobile medical services it finds that mobile medical products have a single function and lack of functions for storing and analyzing a large number of physical data,lack of mobile clients that are compatible with vital signs detection devices such as wireless blood pressure monitors.Then this paper introduced the Android system architecture,commonly used components and common layouts of Android development,summarized the Bluetooth BLE technology,and gave several commonly used data persistence storage methods in Android development.Secondly,based on the Android operating system,this paper proposes a health monitoring App model with a four-layer structure of physical device layer,connection layer,business logic layer,and user interaction layer.This paper provides users with a small and portable wireless medical detection device at the physical device layer;at the connection layer,the mobile phone App and physical devices can communicate via Bluetooth;at the business logic level,the wireless blood pressure meter and other physical devices are measured.The signature data package is parsed,and the result is stored in the database and displayed to the user interaction layer for easy viewing by the user.Again,according to the health monitoring App model,this paper designed and implemented a health monitoring app,and gave the overall functional module design and sub-module design of the app.In the physical device layer,this paper introduces the physical devices such as the wireless blood pressure meter that the App supports,and elaborates the realization process of connection and communication between theBluetooth BLE and the physical device at the connection layer.At the connection layer,this paper elaborates the implementation process of Bluetooth BLE and physical devices to establish connection and communication;the data processing module at the business logic layer describes the realization of functions such as parsing,registration,login,and recovering passwords of physical data packets.And the database module describes the App's database table design and operation of the database's SQL statement.In the interface module,this paper describes the system server interface and GPS positioning,audio and video,WeChat sharing and other use of third-party service interface function implementation;in the user interaction layer describes the implementation of the App section interface.Finally,this paper has written test cases for core functional modules such as physical measurements,completed the installation of the App and sufficient testing work,This illustrates the availability and ease of use of the Health Monitoring App's monitoring functions for body fat,blood pressure,and many other vital signs,and proposes several subsequent improvements to the App.
