摘　　要：设计了一种基于数字光强度传感器BH1750FVI的智能窗帘控制系统。系统以AT89C52为核心控制芯片,接收并处理来自BH1750FVI传感器的光强信号、DS18B20传感器的温度信号、测速传感器的电机转速信号和红外遥控器的控制信号,根据获得的信号向电机驱动电路发出控制信号,控制交流伺服电动机的动作,并利用齿轮传动技术实现智能控制窗帘开度。试验结果表明,智能窗帘控制系统运行稳定,具有方便快捷、灵敏度高和易于操作的优点。Based on an digital light intensity sensor BH1750FVI,an intelligent curtain control system was designed. The core control AT89C52 can receive and deal with light intensity signal prcduced by BH1750FVI,temperature signal produced by DSI8B20, motor rotational speed signal produced by velocity speed sensor and control signal produced by infrared remote controller. At the same time, it can transmit the received signal to motor drive circuit in order to eontrol the operation of AC servo motor, and it can control the opening of the curtain with the technology of gear transmission. The experimental results show that the system could operate steadily with its convenience, high sensitivity and simply operation.
