文档介绍：摘要
在公共场所(例如学校、机关、居民区、厂矿企业等)的楼道中和车流量较小的偏远地区,长明灯现象十分普遍,从而造成了极大的能源浪费。在今天电力能源供应比较紧张的情况下,在没有人员活动的深夜让这些灯关掉一些,不仅可以节约能源,也能够节约一些开支。
本设计采用MCS-51单片机作为主控端与各路灯的控制核心。声音传感器、键盘模块、光敏电阻等作为系统的辅助电路。分别实现了对开关灯时间的控制,不同环境明暗与不同交通情况下的路灯智能控制。
该系统可以设定每只路灯的开关灯时间,还可以通过传感器来识别外部环境的明暗变化和有无车辆与人员通过,是一种实用的路灯控制系统。该控制系统有十分明显的节电效果,同时维修量也大大减少了,从而节约了资金,有良好地使用效果。白天光照强度高,不管过路者发出声音多大,灯泡都不会发亮。夜晚光线变暗,光敏电阻检测到信号,传达至声音检测电路,使其开始工作。当检测到声响时,它就将声音信号传送给单片机,控制路灯打开。几秒钟后,如果没有声响,则再通过单片机来控制路灯熄灭,达到节能节电的目的。
研究该系统的重要性在于利用单片机来控制路灯的亮灭,不仅实现了节能节电的目的,同时提高了对外界环境变化检测的灵敏度,使整个路灯控制系统变得更加智能化。

Abstract
In schools, residentials, organs, mines and other public places of public corridor and few cars in a remote area, the ever-burning lamps phenomena are mon, caused a tremendous waste of energy. Today, electric energy supply es more nervous. However, no personnel activities turn some lights off in the late night, which can not only save energy, but also can save some spending.
This design uses the MCS-51 as the master and as the core control of the street lamp. We use the keyboard module, sound sensors, and photoconductive resistance as the auxiliary circuit of this respectively realized the control of the time to turn off the lights , the intelligent control of the street lamp in different environment and different traffic conditions .
The system can not only set the open time and turn-off time of each street lamp , but also can identify the brightness changes of external environment and sense if there are objects or people passed by . It is a kind of practical control system of the street lamps. Its power saving effect is obvious. At the same time,it helps reduce the maintenance quantity greatly, and save the money. The use effect is good. During the day, no matter how loud a pedestrian voice is, it will still not make the light bulb shine. When the night light is dimmed, the sound detection circuit will work. As long as there is a voice detected, the detected sound will be transmi
