【正文】 模擬路燈控制系統(tǒng) 模擬路燈控制系統(tǒng) I 摘要 隨著電子技術(shù)的發(fā)展，為解決城市路燈照明系統(tǒng)存在的燈光 控制 方法和管理手段落后，所用燈具科技含量低等問題，設(shè)計(jì)了一個(gè)模擬路燈控制系統(tǒng)。采用 SCT89C52 為主控器的模擬路燈控制系統(tǒng)，具有對路燈的定時(shí)設(shè)定功能，也可以分別獨(dú)立控制路燈的開啟和關(guān)閉；能夠同時(shí)具有調(diào)光功能，對路面的光線進(jìn)行調(diào)整，還可以按設(shè)定要求使路燈驅(qū)動(dòng)電源輸出功率在 20%~100%范圍內(nèi)任意調(diào) 節(jié)，調(diào)節(jié)誤差小于 2％。采用高效節(jié)能 LED路燈作為光源，具有系統(tǒng)穩(wěn)定，功耗低等特點(diǎn)。在白天模式的時(shí)候，還能根據(jù)環(huán)境明暗的變化控制路燈的開啟和關(guān)閉路燈，在夜晚模式的情況下，根據(jù)交通路面情況自動(dòng)開關(guān)燈。當(dāng)燈出現(xiàn)故障不亮?xí)r，能夠檢測并且通過聲光系統(tǒng)報(bào)警，顯示器上顯示故障燈的編號(hào)。實(shí)現(xiàn)了路燈的智能化控制，節(jié)省了電力能源和人力資源。 關(guān)鍵詞 ： 定時(shí)設(shè)定 調(diào)光 功率調(diào)節(jié) 檢測故障燈 模擬路燈控制系統(tǒng) II Abstract With the development of electronic technology, In order to solve the lights of the city street light lighting system control methods and management means backward, the lamps and lanterns of science and technology content is low,Design a simulated street light control design is based on the analog controller STC89C52based street light control systems,which have Street lamp time setting function , controling the opening and closing of the street Separately and Light adjusting function, According to set requirements street driving power output power in adjustable within 20% ~ 100%,Adjust the error less than 2% .With high efficiency and energy saving LED lamp as light source, stable system, low power consumption characteristics. At the time of day mode, According to the environmental changes of light and shade light on and off 。 In the case of the night mode, Automatic Switch lamp based on traffic road conditions, when the lights faults have gone, can detect and sound system of the police displayed on the monitor of fault lamp number,Implements the street lamp intelligent control, saves electric energy and human resources. Keywords: Timing settings, Light adjusting, power regulation, Detection of fault lamp. 模擬路燈控制系統(tǒng) III 目錄 摘要 ................................................................................................................
