摘要
设计了一种室内灯光自动控制装置.用平行放置的光电开关划分出照明控制区,用交叉连接的两个74LS74芯片识别进出照明控制区的人数,自动控制室内照明灯光的工作状态.实验结果表明,该装置简便易行、成本低,有效地提高了室内灯光的利用效率.
A device is designed to automatically control the lights in study rooms.The lighting controlled area is divided by two parallel optoelectronic switches.Two chips of 74LS74 in cross connection can record the number of people who get into the lighting controlled area and control the lamp＇s on and off.Experimental results show that the device is easy to operate and cheap.It can effectively improve the efficiency of the use of indoor lighting.
