Design And Implementation Of Health Monitoring System For The Elderly Based On STM32 And Android Technology

The trend of population aging in our country is becoming more and more obvious.With the exacerbation of aging problems,there have been great demands for the home-based care service in China.Implement health monitoring for the elderly is necessary and become the preferred in modern family.In view of above reason,this paper designed a health monitoring system for the elderly based on STM32 and Android technology.This system includes two important aspects,monitoring physiological data and assessment physical and mental health.The specific contents are shown as follows:For the monitoring of physiological parameters,a physiological parameter monitoring terminal based on the STM32 microcontroller was developed in this paper.Multiple sensor modules were selected and the hardware circuit was designed to collect physiological parameters such as ECG,heart rate,blood oxygen,and body temperature in the elderly.for data transmission;mobile phone client based on Bluetooth technology is used to display the collected physiological parameters.And functions such as warning prompts,positioning and calling for help are established;A server and background management platform are built.Besides,community service centers are implemented for the elderly Real-time monitoring and historical data query.For health assessment,this paper presents the “Healthy State Survey Questionnaire(SF-36)” in a mobile phone client in an electronic form so that the elderly can self-evaluate their physical and mental health status at any time and evaluate the results.It is transmitted to the server for reference by doctors.On the other hand,due to the close relationship between physical health status and personal vital signs parameters,A fuzzy comprehensive evaluation method based on neural network is proposed.Through the experimental,the validity and accuracy of this method are proved.Through the test,the monitoring system can realize the accurate detection of human body parameters.And the mobile client function can be realized,which verifies the reasonable and feasible selection of the technical scheme and the reliability of the system.The fuzzy neural network assessment method proposed in this paper provides a new idea for the assessment of the health of the elderly and has a good application prospect.
