基于STC89C52型单片机温控风扇调速系统设计研究

Design and Research of Temperature Control Fan Speed Control System Based on STC89C52 Single Chip Microcomputer

在日常生活中风扇是一种很常见的电器,目前的风扇大多数没有环境温度检测功能,不能根据环境温度实现自动调速,针对这种情况本文设计一种利用单片机和数字温度传感器DS18B20为核心的风扇调速装置,使用单片机及PWM技术实现对风扇电机开启、关闭及转速控制,实现风扇能够根据实际需要自动开、关和自动调速功能,可以根据需要进行设置满足人们的实际使用需求,同时具有节能作用。

In daily life,fans are a very common electrical appliance.Most of the fans at present do not have the function of detecting the ambient temperature and can't realize automatic speed regulation according to the ambient temperature.In view of this situation,this paper designs a fan speed regulation device which uses the single-chip microcomputer and digital temperature sensor DS18B20 as the core.It uses the single-chip microcomputer and PWM technology to realize the control of the fan motor on,off and speed,so that the fan can automatically start according to the actual needs.The off and automatic speed regulation function can be set according to the needs to meet people's actual use needs,and has the function of energy saving.
