摘　　要：随着智能产物在现代生活的普遍应用,人们对智能产物的性能要求越来越高。针对目前无叶风扇低水平控温方式、不先进智能设计的问题,提出了一种基于STM32单片机的无叶风扇智能控制系统设计方案。该方案中控制系统采用热释电传感器作为感应开关,温度传感器DS18B20作为温度采集元件,红外传感器作为测距元件,结合PWM技术控制无叶风扇的送风量,并运用人机交互进行语音控制。通过不断的尝试与检测,该智能产物能根据人与无叶风扇之间的距离和人体温度高低控制风扇的送风量,并可以语音控制风量大小,较好的实现无叶风扇的智能控温,给使用者更智能的体验。With the widespread application of intelligent products in modern life,people have higher and higher requirements for the performance of intelligent products.Aiming at the problems of low-level temperature control mode and non-advanced intelligent design of vaneless fan,a design scheme of intelligent control system for vaneless fan based on STM32 MCU is proposed.The control system in this plan uses pyroelectric sensor as induction switch,infrared sensor as ranging element,temperature sensor DS18B20 as temperature acquisition element,combined with PWM technology to control the air supply volume of vaneless fan,and uses human-computer interaction for voice control.Through continuous trial and detection,it can control the air supply volume of the fan according to the distance between people and the leafless fan and the temperature of the human body.It can also control the air volume by voice,which can better realize the intelligent temperature control of the leafless fan and give users a smarter experience.
