Abstract:

The title of this graduation project is "intelligent hand ring design for the heart rate monitoring for the elderly". An intelligent hand ring for the elderly is used in the age of contemporary intelligence. According to the needs of the elderly, the elderly can help the elderly to monitor the heart rate and reduce the occurrence of the accident.

The design is based on an intelligent heart rate loop developed by STM32 single chip microcomputer, which uses a STM32F103 series of chips as the main control chip to monitor the intelligent heart rate of the max30102 heart rate module by controlling the BLE - CC41 Bluetooth module.

This design uses the traditional design method from bottom to top. Through the realization of each function, the final hand ring is completed. The development process, operation flow and some key technologies of the intelligent hand ring design based on STM32 MCU are expounded.

This paper first introduces the hand ring briefly, including the design purpose and significance of the hand ring research and development, the development background of the hand ring and the development status at home and abroad; the following is a detailed description of each part of the opponent's ring; the next is the Bluetooth design of the hand ring and the design of the PCB, and then the detailed outline of the design of the hand ring is introduced, mainly introducing the analysis of Bluetooth module, And the analysis, making and using methods of app with bracelet, and finally, the test and analysis of software and hardware. Through the realization of the functions of each part, we can make the intelligent bracelet. And analyze the errors and reduce the errors. The last part is the summary of this design, including the problems and design considerations during the design process.

This design is a cooperation project, I mainly in charge of is a hand ring bluetooth function design, including hardware parts and APP, and bracelets, PCB design, another classmate, is mainly responsible for heart rate monitor related the design of the hardware programming and alarm functions, as well as design and so on.
