本要求。2010年全國大學生電子競賽論文設(shè)計題 目: 模擬路燈控制系統(tǒng) 學生姓名: 指導(dǎo)教師: 模擬路燈控制系統(tǒng) 摘要:本系統(tǒng)采用凌陽SPCE061A單片機,構(gòu)成系統(tǒng)的支路控制器和單元控制器。自己制作的LED數(shù)碼管顯示模塊、鍵盤輸入控制模塊、光敏傳感器、光電傳感器、聲光報警模塊等作為系統(tǒng)的輔助電路。系統(tǒng)的單元控制器利用自制恒流驅(qū)動電源,可以使驅(qū)動電源輸出功率在規(guī)定的時間自動減少,完成題目要求的發(fā)揮部分。關(guān)鍵詞:路燈控制 凌陽SPCE061A 恒流驅(qū)動電源Abstract: This system uses Sunplus SPCE061A SCM, constitute a system of tributaries controller and a unit led led display module, keyboard input control module, photosensitive sensors, acoustooptic photoelectric sensors, alarm module, and so on as a system of auxiliary lamps respectively implementation time is displayed and control, different environments and darks and traffic situations Streetlight alarming intelligent control, and so the basic requirements in the topic. System unit controller selfmade constantcurrent drive power, can make driving power output power within the prescribed time automatically, plete the requirements of the play a part of the , the system with dualcore control, in certain vehicles twoway carriageway of plex traffic situations, still can implement smart control on the street。傳統(tǒng)的51 單片機具有價格低廉,使用簡單等特點,但其運算速度低,功能單一,RAM、ROM空間小。 SPCE061A具有豐富的資源:RAM,ROM空間大、指令周期短、低功耗、低電壓、體積小,易擴展,可編程音頻處理,易于編寫和調(diào)試,且獨具語音播報功能等優(yōu)點。綜上分析,選擇方案二。內(nèi)建128*64點陣,有豐富的文字和圖形顯示功能,輕薄便攜,視覺舒適,但液晶顯示不夠鮮明,欠穩(wěn)定,壽命短。LED數(shù)碼管具有顏色鮮艷,亮度高、功耗低、可視角度大和刷新速率快等優(yōu)點;并且通過查閱相關(guān)資料得知,LCD與LED的功耗比大約為10
