51單片機(jī)實訓(xùn)指南:一、 實習(xí)課題基于單片機(jī)最小系統(tǒng)的頻率計設(shè)計二、 實習(xí)內(nèi)容單片機(jī)最小系統(tǒng)電路原理設(shè)計分析與講解，PCB設(shè)計分析與講解，電路板焊接培訓(xùn)與實際操作，程序設(shè)計、調(diào)試分析與講解，程序調(diào)試實際操作。三、硬件資源※ 89S51單片機(jī)；※ 6位共陽極數(shù)碼管；※ 段碼驅(qū)動器74HC573，位選譯碼器74HC138；※ 4路獨立式按鍵；※ 外部晶振電路；※ ISP下載接口（In system program,在系統(tǒng)編程）；※ dc+5V電源試配器（選配）；※ ISP下載線（選配）；※ 單片機(jī)實訓(xùn)模塊（頻率計分頻預(yù)處理電路）。四、電路原理分析與設(shè)計P1為外部電源輸入座（dc+5V），S8為電源最小系統(tǒng)的電源開關(guān)，E1和C3為電源濾波，去耦電容。D1為系統(tǒng)電源指示燈。J2為ISP下載接口，S7系統(tǒng)復(fù)位按鍵。CRY1，C1，C2為外部時針電路。IC1為89S51（DIP-40），左上角為第一腳。PRE1，PRE2。為上拉排阻（阻值4.7k—10k）。J5，J9，J6，J10分別對應(yīng)單片機(jī)的P0，P1，P2，P3口。便于二次開發(fā)。6路共陽極數(shù)碼管動態(tài)顯示電路，P0口通過74HC573（起驅(qū)動和隔離作用，讓電流通過74CH573流入公共地），來控制數(shù)碼管的8路段碼，P20-P22通過74HC138譯碼器（使用其中的6路）控制數(shù)碼管的公共端（中間還有三極管做驅(qū)動器）。這樣設(shè)計的理由：為了保證該單片機(jī)最小系統(tǒng)的二次開發(fā)的資源充足和合理性。

本文設(shè)計出一種新型燈光調(diào)光控制系統(tǒng)。系統(tǒng)采用先進(jìn)的智能功率模塊((IPM)取代以往的可控硅作為功率變換器件,以Intel16 位單片機(jī)為核心控制器采用AC-dc-AC 變換技術(shù)使輸出的波形較可控硅斬波后的波形有很大的改善,這不僅降低了變壓器的損耗而且延長了燈的壽命,提高了系統(tǒng)的運行質(zhì)量。現(xiàn)場總線CAN 的運用使得整個系統(tǒng)便于集中監(jiān)控、管理。調(diào)光器是機(jī)場助航燈光系統(tǒng)的核心控制設(shè)備。目前,國內(nèi)外使用的調(diào)光器主要采用可控硅斬波技術(shù),這種調(diào)光器存在波形畸變大、電網(wǎng)要求高、對電網(wǎng)污染嚴(yán)重、效率低、負(fù)載適應(yīng)能力差等缺點。針對以往系統(tǒng)存在的不足,提出了正弦波調(diào)光器,它采用逆變技術(shù),輸出標(biāo)準(zhǔn)正弦電壓,它的優(yōu)點是對負(fù)載適應(yīng)能力強(qiáng)、對電網(wǎng)要求低、污染輕、效率高、輸出波形好等。正弦波調(diào)光器采用逆變技術(shù),輸出幅度可調(diào)的標(biāo)準(zhǔn)正弦電壓,通過控制算法實現(xiàn)對燈光回路的高精度恒流控制。“正弦波調(diào)光器”將極大地提高調(diào)光器的技術(shù)水平,改善調(diào)光器的性能,增強(qiáng)市場競爭能力。
