本資料是關(guān)于單片機(jī)電路設(shè)計(jì)的一些經(jīng)驗(yàn)，希望對(duì)大家有所幫助。。。 前言 MCU發(fā)展趨勢(shì) 未來(lái)以及相當(dāng)長(zhǎng)的一段時(shí)間內(nèi)，單片機(jī)應(yīng)用技術(shù)的發(fā)展趨勢(shì)為： 1、全盤(pán)CMOS化 CMOS 電路具有眾多的優(yōu)點(diǎn)，如極寬的工作電壓范圍、極佳的本質(zhì)低功耗及功耗管理特征，形成了嵌入式系統(tǒng)獨(dú)特的低功耗及功耗管理應(yīng)用技術(shù)。 2、最大化的SoC設(shè)計(jì) 目前單片機(jī)已逐漸向片上系統(tǒng)發(fā)展，原有的單片機(jī)逐漸發(fā)展成通用型SoC 單片機(jī)(如C8051F 系列)或SoC 的標(biāo)準(zhǔn)IP 內(nèi)核(如DW8051_core)，以及各種專用的SoC 單片機(jī)。 3、以串行方式為主的外圍擴(kuò)展 目前單片機(jī)外圍器件普遍提供了串行擴(kuò)展方式。串行擴(kuò)展具有簡(jiǎn)單、靈活、電路系統(tǒng)簡(jiǎn)單、占用I/O資源少等優(yōu)點(diǎn)，是一種流行的擴(kuò)展方式。 4、8位機(jī)仍有巨大發(fā)展空間 電路常識(shí)性概念(1)-輸入、輸出阻抗 1、輸入阻抗 輸入阻抗是指一個(gè)電路輸入端的等效阻抗。在輸入端上加上一個(gè)電壓源U，測(cè)量輸入端的電流I，則輸入阻抗Rin=U/I。你可以把輸入端想象成一個(gè)電阻的兩端，這個(gè)電阻的阻值，就是輸入阻抗。 輸入阻抗跟一個(gè)普通的電抗元件沒(méi)什么兩樣，它反映了對(duì)電流阻礙作用的大小。 對(duì)于電壓驅(qū)動(dòng)的電路，輸入阻抗越大，則對(duì)電壓源的負(fù)載就越輕，因而就越容易驅(qū)動(dòng)，也不會(huì)對(duì)信號(hào)源有影響;而對(duì)于電流驅(qū)動(dòng)型的電路，輸入阻抗越小，則對(duì)電流源的負(fù)載就越輕。因此，我們可以這樣認(rèn)為：如果是用電壓源來(lái)驅(qū)動(dòng)的，則輸入阻抗越大越好;如果是用電流源來(lái)驅(qū)動(dòng)的，則阻抗越小越好(注：只適合于低頻電路，在高頻電路中，還要考慮阻抗匹配問(wèn)題。另外如果要獲取最大輸出功率時(shí)，也要考慮阻抗匹配問(wèn)題。)

EDA9060開(kāi)關(guān)量I/O 模塊在電氣控制柜中的典型應(yīng)用—— EDA9060結(jié)合交流接觸器實(shí)現(xiàn)遠(yuǎn)程控制EDA9060開(kāi)關(guān)量I/O模塊是山東力創(chuàng)科技自主研發(fā)的一款分布式DI/DO工控模塊，主要功能特點(diǎn)：◎4路開(kāi)關(guān)量輸入，4路繼電器輸出。繼電器兩組常開(kāi)2觸點(diǎn)，兩組常開(kāi)常閉3觸點(diǎn)。輸出觸點(diǎn)容量為8A 125VAC（5A 250VAC5A30VDC），由于觸點(diǎn)容量較大，可以直接用在很多的常見(jiàn)電氣控制電路中。輸出有兩種方式，一種電平式，一種脈沖式，可以靈活配置。◎標(biāo)準(zhǔn)的RS485接口，方便組網(wǎng)，結(jié)合GPRS DTU無(wú)線模塊可以實(shí)現(xiàn)無(wú)線遠(yuǎn)程控制功能。◎靈活的協(xié)議，兼容研華協(xié)議，支持標(biāo)準(zhǔn)MODBUS RTU協(xié)議，方便上位機(jī)的系統(tǒng)組建。EDA9060在電氣控制柜中有著廣泛的應(yīng)用，通過(guò)增加EDA9060遠(yuǎn)程控制線路，改變了原來(lái)必須依靠人工到現(xiàn)場(chǎng)啟停電氣線路的狀況，實(shí)現(xiàn)無(wú)人值守，節(jié)省資源。線路改造主要通過(guò)EDA9060的繼電器輸出控制交流接觸器，從而實(shí)現(xiàn)遠(yuǎn)程控制現(xiàn)場(chǎng)用電設(shè)備（如常見(jiàn)的工業(yè)泵）的啟停。同時(shí)增加一個(gè)轉(zhuǎn)換開(kāi)關(guān)，將手動(dòng)控制線路和EDA9060遠(yuǎn)程控制線路隔離開(kāi)，以保證現(xiàn)場(chǎng)操作優(yōu)先的要求，同時(shí)增強(qiáng)操作的可靠性。下面以交流接觸器控制線路在220V電壓等級(jí)以內(nèi)的常見(jiàn)控制電路為例，簡(jiǎn)要說(shuō)明其控制過(guò)程，線路容量大的情況只需要通過(guò)增加合適容量的中間繼電器，擴(kuò)大EDA9060的觸點(diǎn)容量即可解決，示意圖：
