【正文】 低壓鈉燈：低壓鈉燈光效高（可達(dá)200Lm/w），但需逆變器，低壓鈉燈價(jià)格貴，整個(gè)系統(tǒng)造價(jià)高，采用較少[14]。繼電器在控制系統(tǒng)中的作用有兩點(diǎn)： 傳遞信號(hào)。 CS=1。_nop_()。_nop_()。_nop_()。else value0amp。_nop_()。 P0=date。此時(shí)，設(shè)置的白天與傍晚的電壓臨界值是4V，通過(guò)對(duì)比就可以分析出外界環(huán)境是處于白天還是晚上了；右邊是一個(gè)蓄電池以及充電、放電管理模塊。然而繼電器的開(kāi)關(guān)總是在導(dǎo)通和閉合之間來(lái)回波動(dòng)，形成很大的聲響，造成LED路燈不能正常照亮。同時(shí)也要感謝我的同學(xué)們對(duì)我的幫助，讓我從原來(lái)對(duì)單片機(jī)一無(wú)所知到對(duì)單片機(jī)有所了解再到現(xiàn)在的會(huì)用C語(yǔ)言在keil軟件上編寫(xiě)程序，讓我對(duì)硬件電路的設(shè)計(jì)從原來(lái)懼怕到現(xiàn)在從容查資料，設(shè)計(jì)電路，搭建電路，焊接電路，調(diào)試電路。EmbeddedLED路燈。PTR,1988 1733[15]Janice在后續(xù)的時(shí)間里，我希望可以通過(guò)時(shí)間控制和光控制相結(jié)合的方法來(lái)繼續(xù)這個(gè)設(shè)計(jì)課題并且完善它。所以繼電器的開(kāi)關(guān)閉合，此時(shí)蓄電池就會(huì)持續(xù)給LED路燈供電，達(dá)到照亮的效果。調(diào)試電路的導(dǎo)通性，每個(gè)接口的功能是否都正常等等。 //由1602讀寫(xiě)操作時(shí)序圖，先將指令賦給P0口，延時(shí)后將使能 lcden=1。_nop_()。_nop_()。CLK=0。_nop_()。_nop_()。 系統(tǒng)流程圖 。繼電器的種類(lèi)較多，其工作原理和結(jié)構(gòu)也各不相同。該充電管理模塊的價(jià)格便宜，并設(shè)有兩個(gè)LED指示燈，開(kāi)始工作的時(shí)候，當(dāng)蓄電池開(kāi)始充電時(shí)，紅色指示燈亮；當(dāng)蓄電池停止充電時(shí)，藍(lán)色指示燈亮。鉛酸蓄電池有多種充電形式，主要可分為：恒流充電、恒壓充電、3階段最優(yōu)形式充電。通過(guò)DI數(shù)據(jù)輸入端，可以輕易的實(shí)現(xiàn)通道功能的選擇。本設(shè)計(jì)采用ADC0832模/數(shù)轉(zhuǎn)換芯片，采用串行方式，對(duì)檢測(cè)電壓的緩慢變化比較有利，外圍電路簡(jiǎn)單，價(jià)格便宜。此外，LCD1602采用數(shù)字式接口，與單片機(jī)連線簡(jiǎn)單，故采用LCD1602來(lái)顯示。復(fù)位分為手動(dòng)復(fù)位和上電復(fù)位。此時(shí)， ALE只有在執(zhí)行MOVX，MOVC指令是ALE才起作用。 /RD（外部數(shù)據(jù)存儲(chǔ)器的讀選通）。 P2口：P2口為一個(gè)內(nèi)部上拉電阻的8位雙向I/O口，P2口緩沖器可接收，輸出4個(gè)TTL門(mén)電流，當(dāng)P2口被寫(xiě)“1”時(shí)，其管腳被內(nèi)部上拉電阻拉高，且作為輸入。太陽(yáng)能電池板將采集到的電壓傳輸給單片機(jī)進(jìn)行分析和處理。由于設(shè)計(jì)的是路燈，照明燈具需要足夠的亮度，可以選用LED指示燈用簡(jiǎn)單的發(fā)光二極管即可。太陽(yáng)能路燈免維護(hù)，絕對(duì)安全，不會(huì)發(fā)生觸電事故且可通過(guò)改變控制方式來(lái)增強(qiáng)其穩(wěn)定性。 太陽(yáng)能作為一種可再生的新型能源，很早就被人們開(kāi)發(fā)和利用了。 [關(guān)鍵詞]單片機(jī)；太陽(yáng)能路燈；控制器；照明Design of solar street lamp control systemAuthor:Chang jiao(Grade 2011,Class1,Major of Communication Engineering ,Dept of Electrinics and Information Engineering Shaanxi University of Technology,Hanzhong 723001,Shanxi)Tutor:Xue Zhuanhua[Abstract] With the continuous deepening of sustainable development, the demand for energy is energy as a new kind of clean and renewable energy is recognized as one of the important ways of energy saving and environmental protection., with its long life, energy saving, security, environmental protection , solar street lamp control system is based on STC89C52 microcontroller as the control core, mainly responsible for acquisition of voltage processing through the charging management module automatically to the battery to charge.
