中文摘要：

为满足市场的需要,我们对传统的家用电风扇进行了改进。改善了传统电风扇不能随着环境温度的变化适时调节风力大小的问题。文中设计了一个以STC89C52单片机为控制核心的智能温控电风扇。介绍了温控电风扇的工作原理和三个组成模块,分别是温度采集电路、数码管显示电路和电机调速电路。且系统设计时候采用L298进行驱动,从而起到了很好的调节风扇转速的作用。文中研究的电风扇自动温控装置设计,改变了传统电风扇功能单一、智能性差的特点,提高了它的舒适性和智能性,有利于提高人们的生活质量,因此具有非常重要的应用价值和研究意义。

英文摘要：

To meet the needs of the market, we are improved the traditional household electric fan. To improve the traditional electric fans can＇t as the change of environmental temperature timely adjust the wind size problem. In this paper, we designed a STC89C52 single-chip microcomputer as control core of intelligent temperature control fan. This paper introduces the working principle of temperature control fan and three modules, respectively is temperature acquisition circuit, digital tube display circuit and motor speed control circuit. And the system design is using the L298 to drive, which has played a very good role of regulating fan speed. This paper studies the electric fan automatic temperature control device design, changed the traditional electric fans the characteristics of single function, poor intelligence, improve its comfort and intelligent, to improve people＇s quality of life, so it has very important application value and research significance.
