Design And Implementation Of "Three High"Detection System Based On Android Phone Display

With the improvement of people’s living standards,The incidence of chronic diseases such as hypertension,hyperglycemia,hyperlipidemia,and gout is gradually increasing.In order to meet the needs of patients with chronic diseases,This study designed a "three highs" detection system based on Android phones.The system consists of three parts: the physiological parameter acquisition unit,a central control unit,interactive unit.The central control unit uses STM32F407ZGT6 as the main control chip.Physiological parameters control instruction unit transmitting blood glucose,blood pressure,total cholesterol,and uric acid detecting collection module collects the parameters.And analyze the collected parameters,The analysis results are sent to the LCD in the human-computer interaction unit for lower-level computer display,and then the analysis results are transmitted to the mobile phone through the Bluetooth module for display and analysis of physiological conditions.In terms of mobile phone software,the Android mobile phone is used as a carrier to write a "health steward" APP program to provide users with a series of intelligent services.The first is to scan and connect the Bluetooth module of the lower computer through Bluetooth technology,while receiving and displaying the detection data sent by the lower computer.The second is to establish a SQLite database to store the user’s basic information and detection results.At the same time,the data stored in the database is drawn into a curve through the MPAndroidChart open source library,which is convenient for users to understand the recent changes in physiological conditions more intuitively.The third is to query the relevant data of chronic diseases such as hypertension and hyperglycemia,and use software programming technology to process the data to realize the health analysis function of user detection results.The fourth is to realize the online consultation and medical service functions by obtaining the relevant permissions of the Android phone,which is convenient for users to conduct online consultation directly with relevant doctors and query medical information such as related diseases and drugs.The test results of this system are accurate,small in size,simple in operation,and intelligent.It can simultaneously detect blood glucose,blood pressure,uric acid,and total cholesterol parameters,which is convenient for patients with chronic diseases to monitor their own physiological conditions for a long time.At the same time,it provides a reference for the new model of family medical care in the future.The system detection accuracy is:blood glucose ≤ ± 0.3mmol / L,uric acid ≤ ± 15 umol / L,blood pressure ≤ ± 5mmHg,total cholesterol ≤ ± 0.4mmol / L.
