Design Of Intelligent Elderly Careterminal Based On STM32

With the increasing aging of the social population,the "pension problem" has become one of the social problems that must be paid attention to.At the same time,the vigorous development of intelligent hardware and Internet technology has led to the rapid introduction of intelligent technology into people's daily life,Technology applied to the field of old-age care will be an effective means of care for the elderly.This article is based on STM32 intelligent elderly care terminal design,and multi-physiological parameters of the physical examination instrument,the background server,front-end APP together constitute the intelligent old care system.The system for the "home care" proposed a set of remote monitoring of the elderly activities and health data of intelligent elderly care solutions.The intelligent elderly care solution provides a key SOS emergency call,daily calls,credit card examination,bed bed monitoring,medical data upload,electronic case management and doctor online diagnosis and other functions.The main work of this thesis is as follows:(1)Design the overall structure of intelligent elderly care system.System design is using GSM,GPRS communication technology to achieve daily calls,send and receive text messages and deliver communication between intelligent elderly care terminal and the background server communication,and they are served as the main communication system working for the functions of the system;use 433 MHz wireless communication technology to achieve a key SOS emergency Function of the trigger action transmission;use RFID(radio frequency identification)technology to achieve the user ID access;use Bluetooth communication technology to achieve the communication between intelligent elderly care terminal and multi-physiological parameters of the physical examination to start the physical examination,and get access to using physiology Data;use pressure sensing technology to monitor the elderly in bed,off bed state;depending on Hebei University Brearly Internet of Things intelligent technology laboratory to provide the background server for users to establish electronic case files,to provide doctors online diagnosis;provide theoretical basis,feasibility and design direction achieve various functions in methods.(2)Design of Intelligent elderly care terminal based on STM32.Using the microprocessor STM32F100C8T6 as the system master chip,we have designed the system power supply circuit and the various parts of the external circuit,in order to work with the the core of the five functional unit circuit including SIM800 A communication module,eV1527 encoding and TDH6300 decoding combination,RC522 RF sensor module,BM70 low power Bluetooth module,FSR408 pressure sensor for the intelligent old care system to provide the overall framework of the hardware foundation.In the environment of MDK using C language to write the terminal function of the circuit control procedures,as well as the main program system,let drive hardware circuitachieve the system functions.(3)System debugging.First of all,make a joint debugging of intelligent elderly care terminal hardware and software to make create intelligent elderly care terminal prototype.And then make a data communication protocol intelligent elderly care terminal and the system then add communication test,to achieve intelligent elderly care solutions.After the test,it is clear that STM32-based intelligent elderly care terminal is easy to use,have better function,stable performance characteristics.What's more,and withoutthe WIFI,or no other intelligent terminal support it has a good applicability for the elderly and the elderly family.Relying on a strong background services,the elderly can be remotely cared the establishment of electronic cases can be used as a large data for medical diagnosis to provide a reference.For the medical,family and,society it has a certain development significance.
