摘要
随着健康意识的提升和生活节奏的加快，人们对便捷化健康监测与日常时间管理的需求日益增长。智能手表作为可穿戴设备的重要品类，不仅需要具备基础的时间显示功能，还需集成健康监测与运动管理等实用功能，帮助用户实时掌握自身状态。传统手表功能单一，无法满足用户对健康数据追踪和个性化提醒的需求，因此研发一款集成时间管理、健康监测与运动记录的智能手表具有重要的实用价值。
本设计提出一种基于 STM32F103C8T6 单片机的智能手表。系统主要功能包括：通过 DS1302 实时时钟模块获取当前时间，为用户提供精准的时间显示与管理；借助 MAX30102 脉搏检测模块采集用户脉搏数据，实时监测心血管状态；通过 MPU6050 运动传感器实现步数统计，记录日常运动量；支持按键交互操作，可用于设置步数目标、闹钟时间及开启秒表计时功能；采用 OLED 显示屏分区展示当前时间、当日步数及实时脉搏数据，信息直观清晰；当检测到用户当日步数超过预设最大值时，声光报警模块自动触发提醒，提示运动量已达标。
该智能手表的作用在于融合了时间管理与健康监测功能，为用户提供一体化的可穿戴解决方案。通过高精度传感器采集时间、脉搏和步数数据，满足日常时间规划与健康状态追踪需求；按键交互与可视化显示相结合，操作简便且信息获取高效；步数达标报警功能助力用户科学管理运动强度，培养健康生活习惯。整体设计体积小巧、功耗适中，适合日常佩戴使用，为用户的健康管理和时间规划提供便捷支持。

Design of Smart Watch Based on STM32
Abstract
With the improvement of health awareness and the acceleration of lifestyle pace, people’s demand for convenient health monitoring and daily time management is increasing day by day. As an important category of wearable devices, smartwatches not only need to have basic time display functions, but also need to integrate practical functions such as health monitoring and exercise management to help users grasp their own status in real time. Traditional watches have single functions and cannot meet users’ needs for health data tracking and personalized reminders. Therefore, developing a smart watch that integrates time management, health monitoring, and exercise recording has important practical value.
This design proposes a smart watch based on STM32F103C8T6 microcontroller. The main functions of the system include: obtaining the current time through the DS1302 real-time clock module, providing users with accurate time display and management; Using the MAX30102 pulse detection module to collect user pulse data and monitor cardiovascular status in real-time; Realize step counting and record daily exercise volume through MPU6050 motion sensor; Support button interaction operation, which can be used to set step targets, alarm time, and enable stopwatch timing function; Using OLED display screens to partition and display the current time, daily steps, and real-time pulse data, the information is intuitive and clear; When the user’s daily step count exceeds the preset maximum value, the sound and light alarm module automatically triggers a reminder, indicating that the exercise volume has reached the standard.
The function of this smartwatch is to integrate time management and health monitoring functions, providing users with an integrated wearable solution. Collecting time, pulse, and step count data through high-precision sensors to meet daily time planning and health status tracking needs; The combination of button interaction and visual display makes operation simple and information acquisition efficient; The step count alarm function helps users scientifically manage exercise intensity and cultivate healthy lifestyle habits. The overall design is compact in size and has moderate power consumption, suitable for daily wear and use, providing convenient support for users’ health management and time planning.
