摘　　要：随着人们生活质量的提高,智能家居迅速进入家庭,例如光控自动窗帘。本文采用AT89C52单片机为核心控制器件设计了一款光控自动窗帘,通过两个按钮和光敏传感器控制窗帘的闭合。光敏电阻采集到光信号后由光电传感器PCF8591转化成数字信号传送至单片机,单片机处理后,信号被传送至电机驱动芯片ULN2003,驱动芯片驱动电机进行正转与反转。从实际应用方便的角度出发,又增加了手动功能,无论光照强度如何,都可以进行手动控制窗帘的开合。With improvement of people＇s quality of life, smart home quickly enters the family, such as automatic light control curtain. In this paper, an automatic light control curtain controlled by two buttons and light sensor is designed with AT89 C52 microcontroller. The light signal collected by the photosensitive resistor PCF8591 is converted into digital signals transmitted to the single chip. After the single chip processing, the signal is transmitted to the motor drive chip ULN2003,which drives the chip drive motor to be turned and reversed. In view of the practical application, manual functions have been added. It can be closed manually, regardless of the intensity of light.
