Design Of Multi-function Intelligent Health Watch Based On STM32

Due to the rapid development of economy and science and technology,smart wearable devices are getting more and more attention from the market,allowing more technology companies and individuals to join the R&D team of smart watches,smart wearable devices,and providing a way for people to pursue a healthy lifestyle.A new approach.This article designed a smart health watch based on STM32.The smart health watch not only has traditional wearable products to view time and time,set alarm clock,but also has exercise monitoring,fall detection,heart rate detection,oxygen saturation detection,Blood pressure detection,telephone,text messaging,GPS positioning,music playback,body temperature detection and other functions,but also equipped with a mobile phone APP to control and manage smart watches,allowing users to more easily and quickly operate smart watches,designed to provide users with health management and security Travel guarantees.Motion detection module MPU6050 mainly implements pedometer and fall detection function,fall detection function with SIM808 module to achieve fall detection and help-seeking system;heart rate blood oxygen module MAX30102,get the user’s fingertip or wrist PPG signal,PPG signal through the heart rate detection algorithm and Oxygen saturation algorithm to detect the user’s heart rate and blood oxygen saturation;blood pressure sensor module SON10175 sensor to obtain the user’s PPG signal,through the blood pressure algorithm to process PPG signal to achieve continuous blood pressure measurement function;for body temperature detection module is the first High-precision temperature sensor MLX90615 close to the wrist,collecting wrist temperature,according to temperature changes as a reference data body temperature;SIM808 module through the serial port and STM32 communication,the system by sending AT commands to achieve telephone,text messaging,GPS positioning and other functions;STM32 through ⅡS communication Ways to communicate with the WM8978 module,through STemWin design a simple music player interface,complete the music player song selection,fast forward,cut song,pause,play and tune and other functions.Smartwatch uses STemWin to design the human-computer interaction interface,so that each function of the health watch has the advantages of a good operation interface and easy operation.At the same time,using the real-time operating system uC/OS-Ⅲ to complete the entire smart watch operating system,so that the smart watch system runs more smoothly and stable.After physical tests,the functions of the smart health watch and mobile phone APP performed well and could meet the daily needs of users.
