摘　　要：针对传统风扇智能化水平不足的问题,设计了一款基于AT89S52单片机的智能风扇系统。该系统通过脉冲宽度调制(PWM)技术调节风扇转速,并集成了3种工作模式:手动模式、自动模式和语音模式。在手动模式下,用户可通过按键直接控制风扇的启动、停止及风速调节;在自动模式下,依据环境温度传感器反馈的数据,系统自动调整风扇的运行状态以达到舒适的环境温度;在语音模式下,系统利用SU-03T语音模块识别预设的命令词,实现对风扇的远程控制。详细阐述了各功能模块的工作原理、硬件选型及软件设计思路。经测试验证,该智能风扇系统运行稳定可靠,能够适应多样化的应用场景,有效提升了风扇使用的便捷性和智能化水平。Aiming at the problem of insufficient intelligence level of traditional fans,an intelligent fan system based on AT89S52 microcontroller has been designed.The system adjusts the fan speed through pulse width modulation(PWM)technology and integrates three working modes,such as manual mode,automatic mode,and voice mode.In manual mode,users can directly control the start,stop,and wind speed adjustment of the fan through buttons.In automatic mode,based on the feedback data from the ambient temperature sensor,the system automatically adjusts the operating status of the fan to achieve a comfortable ambient temperature.In voice mode,the system uses the SU-03T voice module to recognize preset command words and achieve remote control of the fan.The working principles,hardware selection,and software design ideas of each functional module are elaborated in detail.After testing and verification,the intelligent fan system runs stably and reliably,which can adapt to diverse application scenarios,and effectively improves the convenience and intelligence level of fan use.
