1、太陽能LED交通警示板設(shè)計(jì)摘要木設(shè)計(jì)采用軟硬件結(jié)合的方式實(shí)現(xiàn)，硬件電路主要包括：充電電路（帶充電保護(hù)功能）、放電保護(hù)電路、傳感電路、計(jì)數(shù)與顯示電路、穩(wěn)壓電路、A/D轉(zhuǎn)換電路、太陽能光伏板自動跟蹤控制系統(tǒng)七個(gè)模塊。AT89S52單片機(jī)是整個(gè)系統(tǒng)的核心部件，通過軟件控制多個(gè)硬件電路的執(zhí)行。在編程時(shí)根據(jù)模塊化的設(shè)計(jì)思路，采用C51語言來編寫程序，主要包括：晝夜的判斷、片天時(shí)通過車輛的計(jì)數(shù)并用LED動態(tài)顯示、夜間警示LED閃爍、防瞬時(shí)光照、控制電機(jī)跟蹤、恢復(fù)電機(jī)到初始位置等模塊。設(shè)計(jì)中實(shí)現(xiàn)了口天計(jì)數(shù)，晚上閃爍，在光控開關(guān)控制下，口天開啟、晚
2、上關(guān)閉的功能，以及防閃電、車燈干擾的功能，并加冇過充、過放保護(hù)裝置。除上述發(fā)揮部分外，又新增兩個(gè)功能：將太陽能光伏板安裝在電機(jī)上，口天時(shí)通過控制電機(jī)旋轉(zhuǎn)來跟蹤太陽，充分利用太陽能，對屯池進(jìn)行充屯；黑夜到來時(shí)，將屯機(jī)復(fù)位到初始狀態(tài)，第二天重新對太陽進(jìn)行跟蹤。關(guān)鍵字：充電，保護(hù)，單片機(jī)，計(jì)數(shù)顯示TheLEDSolarTrafficWarningBoardDesignAbstractThisdesignusesthewayrealizationwhichthesoftwareandhardwareunifies,thehardwareel
