智能电风扇毕业论文

南 华 大 学毕业设计（论文） 精品文档---下载后可任意编辑通过单片机的控制我们实现了电风扇的主要功能：当按下开关键时，系统初始化默认的设定温度为 25 度，假如外界温度高于设定温度电风扇进行运转，假如外界温度高于低于设定温度则枫叶不转动，同时显示外界的温度。当加减键同时按下时进入温度设定状态，可以设置所需的温度，并同时显示所设定的温度，同时按加减键退出设定功能。电风扇的自动控制，让电风扇这一家用电器变的更智能化。克服了普通电风扇无法根据外界温度自动调节转速困难。智能电风扇的设计具有重要的现实意义。关键词：AT89C51 单片机；温度传感器；直流电机。精品文档---下载后可任意编辑Abstract：In daily life, SCM got more and more widely applied in small system, particularly in the application of automatic control system. This thesis based on AT89C51 to design thermostat automatically electric system.Through the MCU control we realized the fan main function：after you press the button，the default system initialization temperature is 25.If the temperature higher than outside temperature，the fan ran. If the temperature is lower than outside temperature the fan doesn't turn and display outside temperature at the same time. When press add key and subtract key,enter the temperature setting system. Then we can set temperature what we needed and display the temperature at the same time. We can exit set temperature system by press add key and subtract key at the same time.The automatic control make electric fan become more intelligent in the household appliances.It overcomes the difficulty which cannot accord the temperature outside automatically to adjust the speed of the normal fan.Keywords：Temperature sensor; Single Chip Machine; D.C. electric machine；目录引言、................................................................................................................................................51、智能电风扇概论.......
