摘　　要：文章设计了一种路灯控制系统,它的硬件主要由美国Cygnal公司的C8051F020单片机、12864液晶显示器、LED恒流驱动电源等组成。C8051F020单片机作为模拟路灯控制系统支路控制核心,实现模拟路灯控制系统的时钟功能,设定显示开关灯时间,并能控制支路按时开灯和关灯;根据环境明暗的变化自动控制开灯和关灯;根据交通情况自动调节亮灯状态;独立控制每只路灯的开灯和关灯时间;当路灯出现故障时,支路控制器发出滴答的报警信号,并显示有故障灯的编号。交通情况采用红外收发传感器方式实现自动调节功能;该系统具有人机界面直观,红外遥控调节方便,系统运行稳定,精度高等特点。A design of a street lamp control system is introduced in this paper, in which the hardware mainly con- sists of the US Cygnal C8051F020 SCM, 12864 LCD and LED constant-current drive power. C8051F020 SCM is the core to control the branch of this system. With this system, it is feasible to do these things ： simulates the function of the street lamp control system clock; set the display time and control lights of branchs in time; control lights automatically according to the changes of brightness; adjust the lights automatically according to the traffic condition; control every light independently; when street lamps come to malfunction, branch controller discretes the warning signal and show the numbers of the faulty lights. Traffic conditions is adjusted automatically by using infrared receiving sensor. This system has a clear combination of human and the machine and it is convenient to adjust through infrared remote control. And the system has a good stability as well as precision.
