Design of intelligent bracelet based on Beidou positioning

Abstract

At present, people are under great pressure to survive, and there are more and more sudden diseases coming along with it. The time that people fail to cure in time due to sudden diseases in society occurs frequently. Therefore, based on this kind of phenomenon, this paper combines fall alarm and Beidou positioning, and designs a new type of fall detection system with STM32 single chip microcomputer as the main control chip, which uses ADXL345 tilt sensor for fall detection, buzzer alarm and remote alarm by sending real-time information through GSM module, so as to timely cure users. In addition, the smart bracelet also has the function of detecting human body temperature and heart rate, and can conduct real-time monitoring of physical conditions. This paper introduces the design idea, hardware selection and software design of the intelligent bracelet, completes the circuit diagram and flow chart of each module, makes the real object and completes the function test, and the results show that the designed product can achieve the preset function. Finally, the paper summarizes the existing shortcomings and prospects for the future of the smart bracelet.
