模拟路灯控制系统报告

下载后可任意编辑模拟路灯控制系统摘要：本文设计了一个以 AT89C51 为控制核心通过多级通信控制的模拟路灯控制系统，本路灯由光电开关实现对定位点处经过物体的精确定位，并将检测的信号经单片机分析处理后控制 LED 灯的亮灭；LED 的电源采纳自制的恒流源驱动；由光敏电阻根据环境光线的变化实现路灯的自动开关；通过调节 PWM 脉冲占空比实现功率的调节，以此达到调光效果。由 DS1302 完成控制器的时钟功能，并通过键盘设定和调整时间。本作品有五总工作模式，其中四种模式可以群控和独立分控甲乙两灯。经检测本路灯可以正常工作。关键词：AT89C51；光电开关；DS1302；光敏电阻；恒流源；PWM脉宽调制脉冲；工作模式Abstract: this paper designs a USES AT89C51 as the core to control the simulation street light control system, the street lamp photoelectric switch to achieve by locating points after the precise orientation in objects, and the detection signal analysis and processing of SCM control LED lights after the light put out, The power of the LED self-made constant current source drive; According to the environment by photoconductive resistance changes of light realize the automatic switch street; By adjusting the PWM pulse of empty the adjustment of the power than implement, to move light effect. By DS1302 complete controller clock function, and through the keyboard and the adjustment of the set time. This work has five total working mode, including four models to group control and independent control points and party b two lights. Via detecting the street lamp can work normally.Keywords: AT89C51; Photoelectric switch; DS1302; Photoconductive resistance; Constant current source; PWM pulse width modulation pulse; Work mode1 系统设计1.1 设计要求设计并制作一套模拟路灯控制系统。控制系统结构如图 1.1 所示：下载后可任意编辑图 1.1 模拟路灯控制系统路灯布置如图 1.2 所示：图 1.2 路灯布置示意图（单位：cm） 1.2 基本要求（1）支路控制器有时钟功能，能...
