1、设计方案智能路灯的控制系统可把分为主机和分机主机部分通过光敏电阻采集路而光信号，来判断是否需要开启或关闭路灯在半夜12点以后，由于路上的行人和车辆明显减少时，道路照明的照度不需要太大，但路灯还在满负荷工作，需要对路灯两端的电压进行调节，此时需要一个定时时钟芯片来定时，到半夜12点后，主机发出控制信号，传给分机要使信号能传给分机需要通过编码电路编码，再通过电力载波发送电路发送控制信号

2、光控开关电路设计光控开关就是根据环境的照度情况，来启动和关闭路灯即当天黑时，能自动开启路灯；当天亮时能自动关闭路灯由此可见，光控开关电路需要检测环境照度，故需要有将光信号转化为电信号的元件，这里我选用了光敏电阻作为环境照度的检测元件

2.1主要元器件选择继电器可以选择欧姆龙G5LA-14-DC9V系列，欧姆龙G5LA系列PCB继电器10A方形1级功率继电器

①带普通引线端子得小型”糖块”式继电器

②获得VDE0435,UL508,CSA

22.2,CQC认证

③高容量10A250VAC

④可提供两种密封:耐焊剂保护型和全密封型

⑤耐脉冲电压4500V以上

⑥线圈功耗360mW

⑦可提供UL class-F绝缘型

⑧漏电起痕电阻:CTI250

⑨无Pb,无Cd由主干线的负载时114A可知，接触器需要承受的负载电流是228A,所以接触器选用CJ12-400CJ12系列接触器是大功率重任务交流接触器，CJ12-400交流接触器的主触头电压时AC220V主触头的电流等级是400Ao晶体管选用S8050,二极管选用1N4007光敏电阻选择GL5528,GL5528的亮阻为10-20k,暗阻为1M图2-1光控开关电器原理图

2.2工作原理随着光照强度的变弱，光敏电阻的阻值变大当光照强度减弱到一定程度时,即光明电阻阻值增大到一定的程度，晶体关Q1导通INT1输出为低电平，这时调用外部中断程序，延时10s,如果INTI输出仍为低电平，则这时使P

0.1为高电平，使晶体管Q

2、Q4导通，这时继电器得电，继电器常开触点闭合从而使接触器线圈KM得电，使接触器常开触点闭合，接通供电电路当天亮时，光敏电阻阻值变小，Q1不能导通，这时需要一个10s的延时程序，这时单片机通过延时判断该这时是否真的到白天了，还是由打雷，灯照或其它情况引起的如果真的到了白天，单片机P

0.1输出低电平Q2,Q4这时不能导通，从而使继电器失电，继电器常开触点断开这样接触器失电，接触器常开触点断开，切断供电电路如果不是白天，单片机P

0.1继续输出高电平。
