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。在今日电力能源供应比较紧的情况下,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。本设计采纳 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,是一种有用的路灯控制系统。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,假如没有声响,则再通过单片机来控制路灯熄灭,达到节能节电的目的。讨论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。[关键词] MCS-51 单片机;智能控制;键盘模块;声音传感器;光敏电阻AbstractIn schools, residentials, organs, mines and other public places of public corridor and few cars in a remote area, the ever-burning lamps phenomena are very common, caused a tremendous waste of energy. Today, electric energy supply becomes 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 system.They 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 con...
