摘要：介紹一種用休眠恢復(fù)方式使單片機(jī)正常運(yùn)行的方法，提高抗干擾能力的方法；分析其適用范圍，提供和使用的電路concretly，結(jié)合實(shí)例，分析這些特點(diǎn)，這種運(yùn)作方式的硬件和軟件設(shè)計(jì)。

關(guān)鍵詞：?jiǎn)纹瑱C(jī)從休眠還原到可運(yùn)行的過(guò)程方法。簡(jiǎn)介：隨著在微電子技術(shù)的飛速發(fā)展，在一個(gè)性能迅速提高電子時(shí)代，在運(yùn)行中表現(xiàn)突出的優(yōu)勢(shì)，邏輯控制，智能方面，更換，擴(kuò)大了測(cè)量，電路組成，控制電路數(shù)字邏輯電路，操作在很大程度上有了很多發(fā)展。但是，因?yàn)樗哂邢到y(tǒng)停止，程序運(yùn)行等關(guān)鍵缺陷，使之限制在一個(gè)很多重要環(huán)境中無(wú)法運(yùn)用的情況。在很多抗干擾技術(shù)中，軟件升級(jí)，設(shè)置添加看門狗電路等，可以解決這個(gè)問(wèn)題，但仍然存在的問(wèn)題還有很多，例如：看門狗的運(yùn)行,意味著已經(jīng)出現(xiàn)錯(cuò)誤和運(yùn)行一段時(shí)間,這是不可以在一些地方出現(xiàn)的,出現(xiàn)錯(cuò)誤流通有時(shí)很多,但看門狗控制聯(lián)系包括和進(jìn)入,通過(guò)和程序的大門,這種錯(cuò)誤看門狗無(wú)法看出；一個(gè)單片機(jī)等待外圍硬件的運(yùn)算需要大量的時(shí)間,將抗干擾程序進(jìn)行運(yùn)行,等待命令。對(duì)于這些情況，我們?cè)噲D恢復(fù)單片機(jī)在外部運(yùn)行的方式，采用或恢復(fù)單片機(jī)休眠狀態(tài)下的方法。根據(jù)外部條件，一個(gè)單片機(jī)替代脈沖的方法?；謴?fù)后的程序，每次的單片機(jī)進(jìn)行相應(yīng)的程序，及時(shí)進(jìn)入休眠完成后進(jìn)行的任務(wù)，等待被恢復(fù)程序。解決了上述問(wèn)題的這種方法，并得到更好的變壓器綜合保護(hù)結(jié)果?，F(xiàn)在把51系列，作為一個(gè)例子，并把具體的方式和實(shí)施方法，作為程序的信號(hào)，來(lái)恢復(fù)單片機(jī)的正常運(yùn)行。所列1.a原理和實(shí)現(xiàn)方法。

1.1恢復(fù)了成經(jīng)常無(wú)條件運(yùn)行的問(wèn)題

使用定時(shí)器，專用時(shí)鐘芯片或其它脈沖發(fā)生器，生產(chǎn)恢復(fù)程序的信號(hào)，定期根據(jù)間隔的設(shè)置。這種方法特別適用于測(cè)量?jī)x器。實(shí)際上，在程序沒(méi)有運(yùn)行中，程序中的A/D轉(zhuǎn)換器通常采用模擬量，然后將其存儲(chǔ)顯示。這當(dāng)然是非常快，但穩(wěn)定的閱讀，每秒只能升級(jí)1-2倍，一對(duì)CPU的大量時(shí)間用于等待的數(shù)據(jù)。讓CPU的開展和任務(wù)結(jié)束后直接進(jìn)入休眠，恢復(fù)程序并喚醒外部運(yùn)行，是要進(jìn)行的下一個(gè)操作，這恢復(fù)了程經(jīng)錯(cuò)誤時(shí)進(jìn)進(jìn)入休眠狀態(tài)的情況，這種方式可以使抗干擾能力大大增強(qiáng)，主要有2點(diǎn):①。在休眠，程序停止運(yùn)行，可以顯示電腦的指標(biāo)，導(dǎo)致無(wú)序程序運(yùn)行和輸出。工作時(shí)間的休眠比例1:9，即1秒時(shí)間有0.1秒測(cè)量使用，顯示，有休眠時(shí)間0.9秒的概率該程序受到干擾的1/10，而運(yùn)行全速，抗干擾能力提高10倍。②因?yàn)槊?秒無(wú)條件恢復(fù)一次程序，一旦停止在目前的工作狀態(tài)，等一定能夠恢復(fù)時(shí)，就會(huì)恢復(fù)到下一次的程序。至于唯一的工具，顯示，一些閱讀錯(cuò)誤，1秒出現(xiàn)意外，沒(méi)有下一個(gè)測(cè)量記憶，是可以承受的，屬于“合格”的錯(cuò)誤。這種恢復(fù)了錯(cuò)誤程序的把關(guān)，定期對(duì)看門狗電路有很大優(yōu)勢(shì)，首先，等待時(shí)間更改為休眠狀態(tài)，時(shí)間縮短，并可能會(huì)受到干擾;第二，避免偶發(fā)的看門狗控制鏈接的錯(cuò)誤循環(huán)的情況。1.2外部條件是恢復(fù)錯(cuò)誤程序的關(guān)鍵有些地方，出口或措施是由外部控制。例如，熱供暖方式，旋轉(zhuǎn)的脈沖產(chǎn)生和計(jì)算出熱水車熱量，沒(méi)有熱水流動(dòng)，沒(méi)有出口的熱量，CPU只需要保持?jǐn)?shù)值，不需要計(jì)數(shù)。可以想像，熱水水車轉(zhuǎn)動(dòng)溫度停車時(shí)，CPU會(huì)處于一個(gè)等待的階段，如果讓其休眠，有水車輪脈搏不斷，抗干擾能力也大大加強(qiáng)。因此，只要恢復(fù)了對(duì)水的車輪和CPU脈沖影響，水車輪旋轉(zhuǎn)一圈，每次連接，CPU是恢復(fù)工作后，熱表就可正常工作，這是恢復(fù)到程序能正常運(yùn)行的方法。類似的應(yīng)用，半電子電度表，在部分程序中斷時(shí)，車輪和機(jī)械程度的循環(huán)轉(zhuǎn)移，用戶不需要電力，CPU已經(jīng)知道所有的休眠時(shí)間。在恢復(fù)的時(shí)間間隔中經(jīng)常不被復(fù)位，但據(jù)證實(shí)了該方法的外部條件。在某些情況下，在休眠的時(shí)間會(huì)很長(zhǎng)，非常有效的提高抗干擾能力。2．硬件實(shí)現(xiàn)的主要問(wèn)題

2.1定期恢復(fù)到可運(yùn)行程序的狀態(tài)

一般有2種方法。①使用theitimer或?qū)Ｓ眯酒瑫r(shí)鐘恢復(fù)程序。圖1，為了使用的時(shí)間電路，555電路構(gòu)成，可以使用X1126等，也喚醒了CPU的報(bào)警信號(hào)后成立的預(yù)警時(shí)間的時(shí)鐘芯片。這種方法適用于長(zhǎng)時(shí)間休眠，也可以按照這個(gè)操作的結(jié)果，確定喚醒時(shí)間，在下次警報(bào)時(shí)恢復(fù)，非常靈活方便。②在使用該系統(tǒng)固有的信號(hào)，是將減少經(jīng)常脈搏。使用50赫茲的頻率來(lái)減少脈沖頻率，已經(jīng)省略了計(jì)時(shí)器，聚集的地方測(cè)量階段在同一時(shí)間的電流信號(hào)的圖，相應(yīng)的信號(hào)。2.2外部條件恢復(fù)到可運(yùn)行程序的狀態(tài)發(fā)送外部條件的脈搏，使恢復(fù)程序，重新直接的一個(gè)重要階段。為此，上述水車輪或電表脈沖產(chǎn)生的花費(fèi)，可以使用施密特觸發(fā)器有一個(gè)新面貌，為寫下最大或最小，可以使用窗口比較工具。為了實(shí)現(xiàn)電子化監(jiān)管，可以使用電子電位器，建立中，隨著單片機(jī)需求持續(xù)降低脈沖。2.3縮短周期，恢復(fù)了可運(yùn)行程序高平時(shí)的電力在圖3，恢復(fù)了程序信號(hào)在高級(jí)別輸出時(shí)，一個(gè)芯片的電腦在恢復(fù)可運(yùn)行程序的狀態(tài)，程序不運(yùn)行，抗干擾能力是最強(qiáng)的，在高層次，一個(gè)芯片計(jì)算機(jī)開始運(yùn)行的行為過(guò)程。這就是說(shuō)，是恢復(fù)程序和時(shí)間的程序進(jìn)行期間信號(hào)運(yùn)輸，這個(gè)時(shí)候應(yīng)大于該程序每次執(zhí)行周期。這是恢復(fù)執(zhí)行周期和恢復(fù)執(zhí)行信號(hào)非常重要的地方，選擇合理方法。至于簡(jiǎn)單的儀器顯示，恢復(fù)程序的周期確定的數(shù)據(jù)打破循環(huán)，低電力是它的措施，對(duì)所有顯示的時(shí)間要大于平時(shí)，
