摘要
近年來，社會經濟因科技快速發展，迫切地需要更為節能的資源作為經濟發展的保障。而公共照明在城市耗能上占比率不可忽視，每年我國在路燈照明上所消耗的電能資源極其巨大，所以在照明這方面方面需要投入研究。目前我國已經主要采用LED（Light Emitting Diode）路燈進行照明，但在節能控制上還存在耗能的問題。
從節能控制和性價比的角度出發，本文提出了以AT89C52單片機為主控制器的LED節能路燈系統方案來實現模擬路燈的節能控制。本系統設計主要由硬件系統設計和軟件系統調試組成，其中硬件系統設計包括單片機最小系統，時鐘模塊，電路控制模塊，LCD顯示模塊，鍵盤控制模塊，按鍵提示音模塊，傳感器模塊等。軟件系統調試主要根據硬件系統，采用系統結構模塊化的方法，分析各個模塊的作用，繪制出整體流程圖，編寫出相應的程序。使得路燈能根據外界環境，交通因素等因素，自動調節路燈亮滅，實現智能控制。

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.
