摘要
设计了一种小型太阳能广告灯箱智能控制系统。该系统采用AT89C51单片机作为主控器件,选用串行实时时钟芯片DS1302提供系统时间,利用光敏电阻作为光控器件,低功耗的串行ROM24C04作为存储路灯开、关时间的数据存储器,采用74LS164驱动的LED数码管作为显示器件。通过光控和时控的结合,傍晚自动开启灯箱电源,晚上十二点自动关闭灯箱电源,早上五点自动开启电源,天亮后光控自动关断。整个系统采用太阳能供电,蓄电池作后备电源,可节约电能。
A small type of solar energy advertising light box with intelligent controlling system is designed, using AT89C51 as main controlling chip, a serial real-time clock chip DS 1302 as timer, a photosensitive resistor as light controller, a low power serial storage street ROM24C04 as time data memory of light swiching-on and -off, 74LS164 drived LED as digital display device, respectively. By combining light controlling and time controlling, the advertising light swiching-on and -off can be controlled automatically. Since the solar energy power is provided for the whole system, with storage battery as standby supply, this system is power saving.
