摘 要
为了提升风扇的智能化水平，本文设计一款基于STM32F103C8T6单片机的智能运动风扇系统，系统通过多种传感器和控制模块实现心率监测、语音、按键和远程控制功能，具有较高的实用性和创新性。
在心率控制模式下，系统根据心率阈值将风扇转速分为低速、中速和高速三个区间，用户可通过手机APP进行心率阈值的设置，满足运动场景下的个性化需求。系统还配备红外避障模块，实现单人追踪和自动关闭功能，提升智能化水平。并通过语音模块实现语音控制，用户可语音控制风扇的开关、调速、摇头以及音乐播放等功能。按键模块则为用户提供手动控制的便利，显示屏用于实时显示心率、模式、摇头状态和音乐状态等信息。通过ESP8266 WiFi模块，系统将监测数据上传至手机APP，用户可远程控制风扇的开关、调速、摇头和音乐播放等功能，并设置心率阈值，切换模式。本研究采用模块化设计方法，将传感器采集、信号处理、控制逻辑和通信传输等功能模块有机结合，实现了系统的高效运行和稳定性能。
本文的研究成果不仅为智能风扇的设计提供了新的思路和方法，还具有较高的理论和实际应用价值，可广泛应用于家庭、运动场所和办公环境等场景，为用户提供更加便捷、舒适和智能化的使用体验。

Abstract
In order to improve the intelligence level of fans, this article designs an intelligent motion fan system based on STM32F103C8T6 microcontroller. The system realizes heart rate monitoring, voice, button and remote control functions through multiple sensors and control modules, which has high practicality and innovation.
In heart rate control mode, the system divides the fan speed into three intervals: low speed, medium speed, and high speed based on the heart rate threshold. Users can set the heart rate threshold through the mobile app to meet personalized needs in sports scenarios. The system is also equipped with an infrared obstacle avoidance module, which enables single person tracking and automatic shutdown functions, enhancing the level of intelligence. And voice control is implemented through the voice module, allowing users to control the fan’s on/off, speed regulation, shaking, and music playback functions through voice commands. The button module provides users with the convenience of manual control, and the display screen is used to display real-time information such as heart rate, mode, shaking head status, and music status. Through the ESP8266 WiFi module, the system uploads monitoring data to the mobile app. Users can remotely control functions such as fan on/off, speed regulation, shaking head, and music playback, as well as set heart rate thresholds and switch modes. This study adopts a modular design approach, organically combining functional modules such as sensor acquisition, signal processing, control logic, and communication transmission to achieve efficient operation and stable performance of the system.
The research results of this article not only provide new ideas and methods for the design of intelligent fans, but also have high theoretical and practical application value, which can be widely applied in scenarios such as homes, sports venues, and office environments, providing users with a more convenient, comfortable, and intelligent user experience.
