【正文】 摘 要 在公共場(chǎng)所（例如學(xué)校、機(jī)關(guān)、居民區(qū)、廠礦企業(yè)等）的樓道中和車流量較小的偏遠(yuǎn)地區(qū)，長(zhǎng)明燈現(xiàn)象十分普遍，從而造成了極大的能源浪費(fèi)。在今天電力能源供應(yīng)比較緊張的情況下，在沒(méi)有人員活動(dòng)的深夜讓這些燈關(guān)掉一些，不僅可以節(jié)約能源，也能夠節(jié)約一些開支。 本設(shè)計(jì)采用 MCS51 單片機(jī)作為主控端與各路燈的控制核心。聲音傳感器、鍵盤模塊、光敏電阻等作為系統(tǒng)的輔助電路。分別實(shí)現(xiàn)了對(duì)開關(guān)燈時(shí)間的控制，不同環(huán)境明暗與不同交通情況下的路燈智能控制。 該系統(tǒng)可以設(shè)定每只路燈的開關(guān)燈時(shí)間，還可以通過(guò)傳感器來(lái)識(shí)別外部環(huán)境的明 暗變化和有無(wú)車輛與人員通過(guò)，是一種實(shí)用的路燈控制系統(tǒng)。該控制系統(tǒng)有十分明顯 的 節(jié)電效果，同時(shí)維修量也大大減少了 ，從而 節(jié)約了資金， 有 良好 地 使用效果。白天光照 強(qiáng)度高 ，不管過(guò)路者發(fā)出聲音多大，燈泡都不會(huì)發(fā)亮。 夜晚光線變暗，光敏電阻檢測(cè)到信號(hào)，傳達(dá)至聲音檢測(cè)電路，使其開始工作。當(dāng)檢測(cè)到聲響時(shí)，它就將聲音信號(hào)傳送給單片機(jī)，控制路燈打開。幾秒鐘后，如果沒(méi)有聲響，則再通過(guò)單片機(jī)來(lái)控制路燈熄滅，達(dá)到節(jié)能節(jié)電的目的。 研究該系統(tǒng)的重要性在于利用單片機(jī)來(lái)控制路燈的亮滅，不僅實(shí)現(xiàn)了節(jié)能節(jié)電的目的，同時(shí)提高了對(duì)外界環(huán)境變化檢測(cè)的靈敏 度，使整個(gè)路燈控制系統(tǒng)變得更加智能化。 【關(guān)鍵詞】 MCS51 單片機(jī)；智能控制；鍵盤模塊；聲音傳感器；光敏電阻 Abstract In schools, residentials, ans, mines and other public places of public corridor and few cars in a remote area, the everburning lamps phenomena are very mon, caused a tremendous waste of energy. Today, electric energy supply bees more nervous. However, no personnel activities turn some lights off in the late night, which can not only save energy, but also can save some spending. This design uses the MCS51 as the master and as the core control of the street lamp. We use the keyboard module, sound sensors, and photoconductive resistance as the auxiliary circuit of this respectively realized the control of the time to turn off the lights , the intelligent control of the street lamp in different environment and different traffic conditions . The system can not only set the open time and turnoff time of each street lamp , but also can identify the brightness changes of external environment and sense if there are objects or people passed by . It is a kind of practical control system of the street lamps. Its power saving effect is obvious. At the same time,it helps reduce the maintenance quantity greatly, and save the money. The use effect is good. During the day, no matter how loud a pedestrian voice is, it will still not make the light bulb shine. When the night light is dimmed, the sound detection circuit will work. As long as there is a voice detected, the detected sound will be transmitted to the microprocessor, then control the lights to open. A few seconds later, the microprocessor will control the lights off, to achieve the purpose of energy saving and electricity saving. The importance of studying the system is to use microprocessor to control the lights, not only to achieve the purpose of energy saving, but also to improve the sensitivity of the detection of changes in the external environment. It will help the entire street lighting system to be more intelligent. 【 Key words】 MCS51 microprocessor。 Intelligent control。 Keyboard module。 Voice sensor。 Photoconductive resistance 目 錄 第 1 章 緒論 .................................................................................................................. 1 前言 ........................................................................................................... 1 選題背景 ................................................................................................... 1 課題研究的目的和意義 ........................................................................... 1 第 2 章 方案設(shè)計(jì)與論證 .............................................................................................. 3 主控系 統(tǒng)的選擇 ................................
