摘　　要：随着单片机的广泛应用,人们对智能化的要求越来越高。本系统采用STM32F407ZGT6单片机作为处理器,配合DS18B20温度传感器模块,TFTLCD彩屏液晶屏模块,独立按键模块和L9110电机驱动风扇模块完成产品设计。本设计使用TFTLCD实时显示DS18B20获取的温度,以及实时时钟和风扇转速信息;风扇的转速既可直接由独立按键控制,又可通过按键选择进入温控调速状态,由环境温度自动调节转速高低。经实际测试,设计实际可行,可完全满足设计要求。With the wide application of microcontrollers,people’s demand for intelligence is higher and higher.The system adopts STM32F407ZGT6 microcontroller as the processor,with the DS18B20 temperature sensor module,TFTLCD color screen module,the independent key module and the L9110 motor driven fan module to complete the product design.This design uses TFTLCD to display the temperature obtained by DS18B20 in real time,as well as the display of real-time clock and fan speed information.The fan speed can be directly controlled by an independent key,or the keys can be selected to enter the temperature-controlled speed regulation state,and the speed can be automatically adjusted by the ambient temperature.The practical test shows that the design is feasible and can fully meet the design requirements.
