摘　　要：针对传统路灯控制系统使用中存在的问题,提出了以单片机为控制核心,由RS485通信、光电检测物体运动和PWM调制恒流驱动模块共同组成的LED路灯控制系统设计方案。该控制系统主要由单元控制器和支路控制器组成。单元控制器具有移动物体检测、环境光线检测、路灯驱动及故障检测等功能;支路控制器具有人机交互、故障报警、日历显示等功能。整个控制系统设计了四种自动开关灯模式,模式之间可以任意切换,实现了LED路灯系统多模式智能控制。According to the problems existing in the traditional streetlight , a new method inclusive of the controlling core based on MCU , the communication of RS 485 , detecting the object motion by photoelectric and constant-current driving module by PWM modulation is given in the article .The control system is made of unit controller and branch controller .The functions of unit controller include object motion detection , the light-detection of surroundings , streetlight driving and fault detection .The branch function has the ability of human-computer interaction , fault alarm and calendar displaying .Four models of auto-switch are designed in the system , each pattern can be changed easily , the multi-mode of streetlight system is achieved .
