摘要
此次设计一款通过检测温度自动控制风扇转动的系统，该系统采用STM32单片机作为此次设计的核心控制模块，采用温度检测模块DS18B20对温度进行检测，通过人体红外检测是否有人，没人自动关闭风扇。在进行温度的设置过程中，用户可以按照自己的需求设置的最高温、最低温和风扇转动时间等值，当系统正常进行工作时，当温度大于设置最小值且小于最大值和最小值的中间值，则启动风扇以一档的速度转动；当温度大于最大值和最小值的中间值且小于最大值，则启动风扇以二档的速度转动；当温度大于设置最大值，则启动风扇以三档的速度转动。经过实物测试，此次设计的系统控制较为准确，且工作较为稳定。

Abstract
This design is a system that automatically controls the fan rotation by detecting the temperature. The system uses STM32 single-chip microcomputer as the core control module of this design, uses the temperature detection module DS18B20 to detect the temperature, and detects whether there is anyone through human infrared, and nobody automatically turns off the fan. During the temperature setting process, users can set the maximum temperature, minimum temperature and fan rotation time equivalent according to their own needs. When the system works normally, when the temperature is greater than the minimum value and less than the middle value of the maximum and minimum values, start the fan to rotate at the speed of one gear; When the temperature is greater than the middle value between the maximum value and the minimum value and less than the maximum value, the starting fan rotates at the speed of second gear; When the temperature is greater than the set maximum value, the starting fan rotates at the speed of three gears. Through the physical test, the system control designed this time is more accurate and stable.
