摘　　要：针对传统风扇转速单一、无法实现人体感知及自动启停的问题,设计了一款具有红外感应、灵敏温度感测及显示功能的智能风扇控制系统。系统依据红外热释电传感器的人体感应信号,控制风扇的启停;将温度感应采集的实时环境温度与用户设置的温度上下限值进行比较,控制风扇的强弱运行。风扇的运行状态依据环境温度而定,从而有效解决了传统风扇不能随环境温度的变化自动调节风速的问题。所设计的智能风扇具有价格低廉、挪动方便、智能自控、节能等诸多优点,具有较好的应用前景。Aiming at the problem that the traditional fan is in single speed and unable to realize human perception and automatic start-stop,an intelligent fan control system integrating infrared sensing,sensitive temperature sensing and display functions is designed. The system controls the fan＇s operation and stop according to the human body sensing signal of the infrared pyroelectric sensor. In accordance with the real-time ambient temperature of the temperature sensing and the upper and lower limits of the temperature set by the user,to control the fan＇s strong and weak operation. The operating state of the fan is determined according to the ambient temperature,which effectively solves the problem that the conventional fan cannot automatically adjust the wind speed with the change of the ambient temperature. The designed intelligent fan has many advantages such as low cost,convenient movement,and intelligent self-control,etc,and it has good application prospects.
