LED路灯节能控制装置设计(附电路原理图,PCB图,仿真程序)(任务书,开题报告,论文13300字,电路原理图,PCB图,仿真程序)
摘要
近年来，社会经济因科技快速发展，迫切地需要更为节能的资源作为经济发展的保障。而公共照明在城市耗能上占比率不可忽视，每年我国在路灯照明上所消耗的电能资源极其巨大，所以在照明这方面方面需要投入研究。目前我国已经主要采用LED（Light Emitting Diode）路灯进行照明，但在节能控制上还存在耗能的问题。
从节能控制和性价比的角度出发，本文提出了以AT89C52单片机为主控制器的LED节能路灯系统方案来实现模拟路灯的节能控制。本系统设计主要由硬件系统设计和软件系统调试组成，其中硬件系统设计包括单片机最小系统，时钟模块，电路控制模块，LCD显示模块，键盘控制模块，按键提示音模块，传感器模块等。软件系统调试主要根据硬件系统，采用系统结构模块化的方法，分析各个模块的作用，绘制出整体流程图，编写出相应的程序。使得路灯能根据外界环境，交通因素等因素，自动调节路灯亮灭，实现智能控制。

Design of Street LED Lamps Energy-saving Control Facility
Abstract
For years, boom of society owing to the rapid of technological and scientific progress, it is urgently to need more energy-saving resources as a guarantee to support economic development. The rate of consumption of lighting in the city cannot be ignored. Every year, the energy consumption of the electric energy consumed by the street lamps in our country is enormous. Thereby we must be dedicated to investment research in this part. At present, though our country has already mainly used street LED lamps for lighting, there is also some problem of energy consumption in the energy-saving control.
From both of the perspective of energy-saving control and cost performance, the paper proposes a kind of street LED lamps energy-saving system based on AT89C52 single-chip as the main controller to realize the energy-saving simulation control of street lamps. The design of system mainly is made of hardware designing and software debug, the hardware system design includes MCU minimum system, clock module, the circuit control module, LCD display module, keyboard control module, key tone module, sensor module. And the software system mainly according to hardware system use structure method to analysis the function of each module, to draw the whole process graph and to write out the corresponding program. To achieve street lamps can automatically adjust according to external environment and traffic factor, and realize intelligent control.
