基于单片机的声光双控开关的设计

摘要:该设计主要介绍的是关于声光控的电路设计。声光控是通过光敏电阻来实现的，当光敏电阻在背光的的时候灯就会慢慢的熄灭，即这时也是人走过了的时候。在有的电路中这种原理也可以通过声音的振动来实现，当人走过是只需用手轻排一下灯就会自动的亮，人离开后又熄灭。这样就给路人提供了相应的方便，同时，也达到了节电和节能的目的；延长灯的寿命。在实际生活中节电节能，能够实现更多的自动化。在本设计中介绍了声光控路灯控制器的组成、性能，适用范围及工作原理，给出各电路原理图及元件参数选择，节电效果十分明显，同时也大大减少了维修量、节约了资金，使用效果良好。白天光照好，不管过路者发出多大声音，灯泡都不会发亮。夜晚光暗，电路的拾音器只要检测到有碎发声响，就会自动亮为行人照明，过数十秒后又自动熄灭，节能节电。关键词：自动控制；节能；光电开关；声控电路；光控电路；

Based on SCM acousto-optic dual control switch design

（The Department of Physics and electronics Chaohu College, ChaoHu 238000）Abstrac：This design is mainly introduced in the circuit design steerable about sound. Acoustic light-activated is realized by photoconductive resistance, when the backlight photoconductive resistance when light will slowly extinguished, namely then also is a person walked. In some circuit this principle could be realized by the vibration of the voice, when people walk is to simply with handle gently row about lamp will automatically light, people left and put out. Thus to passers-by with a corresponding convenience, at the same time, also achieved power saving and energy-saving purpose; Prolong lamp life. In actual life saving energy saving, can realize more auto main schools, offices, factories and enterprises

and other units public and residential public corridor, ever-burning lamps phenomena are very common,

this creates a tremendous waste of energy. In addition, due to frequent switch or man-made factors, wall switch, increasing the damage rate high maintenance, waste money. Meanwhile, in order to improve our analog electronic technology and digital electronic technology understanding and consolidated, I spent a month's time for graduation design, and I design topic is the design of acousto-optic control floodlight, I designed a circuit novel, safety section, simple structure, convenient installation, service life long acousto-optic double accused of incandescent lamp energy-saving lighting. In this design is introduced in

the variety of acoustic light-activated street lamp controller, the scope of the composition, properties and

its working principle, the circuit principle diagram and given device parameters selection, power saving effect is apparent, also greatly reduced maintenance, saving money, use effect is good. Daytime light job, whether out passers-by voice, lamp will not light. when light comes, circuit pick-up as long as detect have broken hair ring, will automatically bright lighting, several seconds later , and effective energy saving.

一综述

整个电路由电源电路，放大电路，处理电路（声控电路、光控电路）及延时电路等

部分组成。电源由太阳能电池供电，光敏控电路对外界光亮程度进行检测，输出与光

亮程度相对应的电压信号。从而实现白天灯泡不亮晚上遇到声响时，通过声控电路使

灯泡自动点亮，声控电路主要将声音信号转变为电信号，从而要实现自动控制，延时
