基于CD4011的声光控延时节能开关电路系统设计

Abstract院In order to alleviate the increasing energy crisis and realize the strategy of sustainable development owing to the limitedresources 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 theself-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 andenvironmental it will be widely used in our daily life.院集成电路 声光控 CD4011 电路设计Key words院integrated circuit acousto-optic control CD4011 circuit design中图分类号院TM564 文献标识码院A 文章编号院1006-4311（2014）31-0059-02
