摘　　要：设计了一套LED路灯模拟控制系统。系统采用单片机控制,由支路控制器和单元控制器构成,控制器间采用多机串行通信方式通信,以两路1W的LED灯控制系统模拟两个单元控制器,采用恒流电路驱动,通过多种控制方式,如定时控制、根据环境光线明暗控制、根据交通情况控制及LED灯的短路和断路故障报警等,实现了LED灯的节能和智能控制。制作表明,本系统达到了较高的技术指标.This paper introduces a LED street light simulating control system. The system controlled by MCU, consists of branch controller and unit controller, the communication between controllers is multimachine serial communication, and two unit controllers are simulated by two 1W LED controllers, driven by constant current circuit, and through a variety of control mode, such as timing control, according to the ambient light control, according to the traffic flow control and LED lights short and open fault alarm, realizing the energy saving and intelligent control of the LED lights. Production shows that the system has reached a higher technical indicator.
