摘要
针对目前无叶风扇自动控制水平低的问题,提出了一种基于多传感器的无叶风扇控制系统设计方案。系统采用热释电传感器HC-SR501、红外传感器GP2Y0A02YK0F分别进行了人体位置及人与风扇之间距离的检测,并运用PWM技术控制了无叶风扇的风速。实验测试表明,此系统可跟随人体位置变化自动调整无叶风扇的吹风角度,能根据人与无叶风扇之间的距离控制风扇的出风速度,并在一定范围内为使用者提供恒定的吹风速度和良好的吹风感受,较好地实现了无叶风扇的智能控制。
Aiming at the problem of low automatic control level for the existing bladeless fan ,a design scheme of the bl-adeless fan control system based on multi-sensors is presented .The system uses the pyroelectric sensor HC-SR501 and the infrared sensor GP2Y0A02YK0F to detect the body position and the distance between human body and bladeless fan respectively ,and applies PWM technology to control the wind speed of the bladeless fan .Experiments show that this system can automatically adjust the blowing angle of bladeless fan in accordance with the body position changes ,and can control the wind velocity of bladeless fan according to the distance between human body and bladeless fan .Further ,the system can provide constant blowing speed and good blowing feeling for the user within a certain range ,and can better realize the intelligent control .
