一种简易温控智能风扇控制系统的设计

摘要

为了实现温度对电风扇的智能控制,设计并制作了一种以AT89C51为控制核心的简易智能风扇控制系统,包括硬件和软件两部分,重点介绍DS18B20对温度检测的方法及利用温度如何实现风扇的智能控制.该系统通过仿真和实物测试,可实现温度的显示及根据温度智能控制风扇的开启和关闭,且具有电路结构简单、操作客易、硬件少、成本低等特点.%In order to realize the intelligent temperature control in electric fans, a simple intelligent fan control system with AT89C51 as control core is designed and produced, which includes two parts, hardware and software. The DS18B20 temperature detection method and how the fan realizes the function of intelligent temperature control are emphasized. The simulation and test results show that the system achieves temperature displaying and realizes intelligent opening and closing of fans in response to temperature changes and has the advantages of simple circuit structure, easy operation, less hardware and low cost.
