Design of Temperature-controlled Fan based on 51 Single Chip Microcomputer

本文设计并制作了一款基于51单片机的智能温控风扇。电路系统主要由51单片机、数字式集成温度传感器、数码管显示器、机械风扇、四位按键等构成。使用Proteus对电路进行仿真,得到智能温控风扇的仿真电路图。按照电路图焊接完成硬件电路,并对硬件电路进行调试。调试结果表明:将实物连通电源,并设置预设温度临界点,便可实现随环境温度变化而变换档位的智能温控风扇。该智能温控风扇性能稳定,适用性强,既可用做汽车冷却风扇,也可用做其他机械或电子设备的散热装置。

An intelligent temperature-controlled fan system based on single chip microcomputer is designed and manufactured in this article.The circuit system is mainly composed of 51 single-chip microcomputer,digital integrated temperature sensor,digital tube display,mechanical fan,four buttons and so on.The simulation circuit diagram of intelligent temperature control fan is obtained based on Proteus.According to the circuit diagram,the hardware circuit is manufactured and debugged.The debugging results show that:by connecting the physical object with the power supply and setting the preset temperature critical point,the intelligent temperature control fan can change gear based on the ambient temperature.The intelligent temperature control fan has stable performance and strong applicability.It can be used not only as a cooling fan for automobiles,but also as a heat sink for other mechanical or electronic equipment.
