MULTISM课程设计题目简易声光控延时开关学院管理科学与工程学院专业电子信息工程班级12信工（1）班学 姓名孔志伟指导老师高玲2014年12月摘要本设计主要目的是设计简易声光控延时照明灯电路，介绍其组成、性能及工作理，给出电路原理图及元件参数选择。该电路节电效果十分明显，白天光照好，不管过路者发出多大声音，都不会使灯泡发亮。夜晚光暗，电路的驻极式传声器只要检测到有声响，就会自动点亮为行人照明，过段时间后又自动熄灭，节能节电。本电路采用两级控制（光线强弱的感应与声强的感应）。光控电路是根据光线的强弱来优先决定电灯的亮灭。该电路可以对声控延时电路进行控制，在白天光线较强时，光控电路输出低电平将声控电路封锁；在晚上光线较弱时，光控电路输出高电平，则声控功能打开。声控电路中采用了双三极管构成的放大电路，将MIC转化的电信号连续放大，通过延时电路控制灯亮及灯亮的时间。随着现代智能建筑技术的快速发展，智能照明控制技术越来越显现出重要的作用。它区别于以开关量、手动为主的照明控制方式，具有节能环保、安全稳定、使用灵活等特点。在日常生活中，这种延时照明控制灯能有效地消除长明灯、节约电能，可广泛用于楼梯、走廊、路灯和厕所等场所的照明。 ABSTRACTPurpose of this design is to design simple optical delay lighting circuit, introduces the composition, performance and working principle, gives the principle diagram of the circuit and component parameter selection. The circuit power saving effect is obvious, good light during the day, no matter how much sound, passers-by will not make the bulb light. Night light from the darkness, and the circuit in a microphone as long as there is noise is detected, it will automatically light for pedestrians lighting, after period of time and automatically extinguished, energy-saving power saving. This circuit USES two level control (light induction and induction of sound intensity). Electric circuit is the basis of the intensity of light to decided to destroy the light of the light. This circuit to control the audio delay circuit, strong light during the day, the electric circuit output low level acoustic control circuit is blocked; In the evening light weaker, the electric circuit, the output level is open voice control function. Voice control circuit adopts double triode amplifying circuit, MIC into electrical signal continuous zoom, through time delay circuit to control the light and the light. With the rapid development of modern intelligent building technology, intelligent lighting control technology reveal more and more important role. It differs from predominantly switch, manual and lighting control, energy saving, environmental protection, securi
