基于单片机的温度控制风扇的设计 专业资料参考 PAGE 2 word格式整理 摘 要 基于温度传感器和51系列单片机控制技术，设计了一种智能温控调速风扇。本毕业设计的温控风扇利用温度传感器DS18B20来检测外界环境的温度，利用数码管显示外界环境温度、设定的开启温度以及温度差和档位，可以通过控制按键调节设定的开启温度以及温度差，风扇共有五个档位，根据PWM(Pulse Width Modulation)可以控制调节风扇速度。本论文阐述了智能温控调速风扇的工作原理、硬件设计、软件实现的过程。 电风扇的自动控制，可以更加便于人们对风扇的使用。克服了普通电风扇无法根据外界温度自动调节转速困难。因此，智能电风扇的设计具有重要的现实意义。 关键词 单片机；温度传感器 ；直流电机；PWM 专业资料参考 ABSTRACT Based on the temperature sensor and 51 series single-chip microcomputer control technology，we designed a kind of intelligent temperature control fan. In this course design of temperature control fan we use temperature sensor DS18B20 to test the temperature of the external environment. We used the digital tube to display the outside temperature and set the temperature and the temperature difference and gears. The fan can be regulated by controlling the buttons to set the temperature and the temperature difference In this design we expound the intelligent temperature control fan, and the working principle, hardware design, software implementation process. The fan has five gears based on PWM(Pulse Width Modulation)to control the fan’s speed. The automatic control of electric fan can be more convenient for people to the use of the fan. And it overcome the problem that ordinary electric fan cant adjustment speed according to the ambient temperature automatic. Therefore, the design of intelligent electric fan has important practical significance.
