基于CD4011的声光控延时节能开关电路系统设计

为缓解日益紧张的能源状况,实现社会的可持续发展要求,结合声学、光学和延时技术设计出声光控延时节能自动照明开关电路系统,该系统能够实现:在光控电路作用下,开关断开并自锁,照明灯不亮;在无光线或光照不足时,通过脚步或手拍等声音接通电路,照明灯开启,并延时一段时间后自动熄灭。设计出的开关可广泛地应用于楼道、建筑走廊、厕所等场所,是一种理想、环保的照明开关。

Design of Circuit System for Acousto-optic Control Delay Energy-saving Switch Based on CD4011

In order to alleviate the increasing energy crisis and realize the strategy of sustainable development owing to the limited resources, the circuit system for acousto-optic control delay energy-saving switch was designed by optics, acoustics and delay technique. The circuit system was principally illustrated as follows： under the action of the light control circuit, the switch broke away and started the self-locking device. Then the circuit could make the light turn off. When received sound of walking or handclap at certain degree of dark, the circuit worked and turned on the lights. After a while, it turned off the lights automatically. As a new switch, which is ideal and environmental, it will be widely used in our daily life.
