Development Of Intelligent Health Care And Service System For The Elder

As the population ages,the problem of chronic diseases in the elderly is more common,which makes people pay special attention to the health of the elderly.In order to provide more monitoring of the health status of the elderly,this paper designs an intelligent health care and monitoring system based on biomedical electronic technology,embedded system technology and mobile phone software development technology.The whole system is divided into two parts,one is the hardware circuit design of the signal acquisition end,and the other part is the software program design.The hardware circuit includes the main control chip,the physiological parameter acquisition module,the extended SD card storage,the communication module and the power supply module.The main control chip selects STM32F407ZGT6 as the core processor to control the hardware of the system,including physiological parameter acquisition,data analysis and processing,single-chip computer and mobile terminal communication.The physiological parameter collection module mainly includes six parts: electrocardiogram,blood pressure,blood oxygen saturation,blood sugar,body temperature and pulse.The collected physiological parameters are processed by the CPU and transmitted to the Android mobile phone for monitoring.The accuracy of each module detection parameter: heart rate ? ± 5bp,blood pressure ? ± 5mmHg,blood oxygen ? ± 2%,blood glucose ? ± 0.2mmol / L,body temperature ? ± 0.1 ° C.The software program design uses the Java language to write a service system named “Smart Medical” on the mobile phone.This system has designed specific service functions for the elderly.First,establish a personal health record for each elderly person and record the basic information of the elderly,family contact information and historical data query.The second is to establish a health care service system,including: health monitoring,health consultation,medication alarm clock reminder.In order to make the system more convenient for the elderly,it has more humanized functions.One is that the single module physiological signal collection is one-button detection;the other is to facilitate the elderly to use the service on the mobile phone,only need to input the elderly's respective services.The center number can be used to log into the old-age service platform,which saves the trouble of filling in login information and facilitates the operation of the elder.This system provides an idea for responding to the health care service model of the aging society,applying concept of service to the system,and integrating health monitoring and medical services in the intelligent old-age health monitoring and service system.
