1、基于multisim的声光控楼道灯照明电路的设计与仿真摘要现在，在很多的公共场所中依然存有很多旧式的照明。需要人去触发开关来工作，十分不便捷，没有实现照明智能化。而且灯光由于人为疏忽等原因长时间处于工作状态的现象很普遍，这造成了社会能源的极大浪费。另外，由于经常开关或者其他因素损坏率很高，增大了维护的资金的支出和保养成本。为了能在一定程度上解决这些问题，设计了声光控路灯新式控制系统。本系统的工作原理是：电源模块对整个电路提供稳压直流电，光敏电阻和咪头用来探测光和声音信号，LM324构成比较电路对信号进
2、行放大，74LS08D的与门逻辑电路对信号的筛选，从而对开关发出开启或关闭的命令信号。继电器控制和驱动灯泡，RC充放电路起到延时作用，实现自动控制灯的亮灭。当光线和声音都达到触发开关的条件时，灯会自动点亮并延时20秒左右熄灭。此系统能自动控制路灯的亮灭，即在有声音和阴暗情况下亮灯，其他情况下灭灯，从而达到智能节约的效果。该系统结构简单效果明显可广泛应用于各种场合。关键字：声光控制；LM324；继电器；延时AbstractNow,inpublicplacesandpubliccorridor,light
