故障多發(fā)點在閥門或閘板這一類的設(shè)備上，因為這類設(shè)備的關(guān)鍵執(zhí)行部位，相對的位移一般較大，或者要經(jīng)過電氣轉(zhuǎn)換等幾個步驟才能完成閥門或閘板的位置轉(zhuǎn)換，或者利用電動執(zhí)行機構(gòu)推拉閥門或閘板的位置轉(zhuǎn)換，機械、電氣、液壓等各環(huán)節(jié)稍有不到位就會產(chǎn)生誤差或故障。長期使用缺乏維護(hù)，機械、電氣失靈是故障產(chǎn)生的主要原因，因此在系統(tǒng)運行時要加強對此類設(shè)備的巡檢，發(fā)現(xiàn)問題及時處理。我廠對此類設(shè)備建立了嚴(yán)格的點檢制度，經(jīng)常檢查閥門是否變形，執(zhí)行機構(gòu)是否靈活可用，控制器是否有效等，很好地保證了整個控制系統(tǒng)的有效性。

? ?故障點可能發(fā)生在開關(guān)、極限位置、安全保護(hù)和現(xiàn)場操作上的一些元件或設(shè)備上，其原因可能是因為長期磨損，也可能是長期不用而銹蝕老化。如該生產(chǎn)線窯尾料球儲庫上的布料行走車來回移動頻繁，而且現(xiàn)場粉塵較大，所以接近開關(guān)觸點出現(xiàn)變形、氧化、粉塵堵塞等從而導(dǎo)致觸點接觸不好或機構(gòu)動作不靈敏。對于這類設(shè)備故障的處理主要體現(xiàn)在定期維護(hù)，使設(shè)備時刻處于完好狀態(tài)。對于限位開關(guān)尤其是重型設(shè)備上的限位開關(guān)除了定期檢修外，還要在設(shè)計的過程中加入多重的保護(hù)措施。

? ?故障點可能發(fā)生在PLC系統(tǒng)中的子設(shè)備，如接線盒、線端子、螺栓螺母等處。這類故障產(chǎn)生的原因除了設(shè)備本身的制作工藝原因外還和安裝工藝有關(guān)，如有人認(rèn)為電線和螺釘連接是壓的越緊越好，但在二次維修時很容易導(dǎo)致拆卸困難，大力拆卸時容易造成連接件及其附近部件的損害。長期的打火、銹蝕等也是造成故障的原因。根據(jù)工程經(jīng)驗，這類故障一般是很難發(fā)現(xiàn)和維修的。所以在設(shè)備的安裝和維修中一定要按照安裝要求的安裝工藝進(jìn)行，不留設(shè)備隱患。

? ? 故障點是傳感器和儀表，這類故障在控制系統(tǒng)中一般反映在信號的不正常。這類設(shè)備安裝時信號線的屏蔽層應(yīng)單端可靠接地，并盡量與動力電纜分開敷設(shè)，特別是高干擾的變頻器輸出電纜，而且要在PIC內(nèi)部進(jìn)行軟件濾波。這類故障的發(fā)現(xiàn)及處理也和日常點巡檢有關(guān)，發(fā)現(xiàn)問題應(yīng)及時處理。

? ? 故障主要是電源、地線和信號線的噪聲(干擾)，問題的解決或改善主要在于工程設(shè)計時的經(jīng)驗和日常維護(hù)中的觀察分析。

? ? 要減小故障率，很重要的一點是要重視工廠工藝和安全操作規(guī)程，在日常的工作中要遵守工藝和安全操作規(guī)程，嚴(yán)格執(zhí)行—些相關(guān)的規(guī)定，如保持集中控制室的環(huán)境等等，同時在生產(chǎn)中也要加強這些方面的霄理。

? ? 過程控制系統(tǒng)本身是一個完整的系統(tǒng)，所以在分析故障或處理故障時也要注意系統(tǒng)性，單獨的對某一部分的優(yōu)化有時并不能提高系統(tǒng)的整體性能。如過分追求元器件的精度而不考慮實際的需要以及和相關(guān)設(shè)備精度的匹配，將徒然增加系統(tǒng)成本。在日常維護(hù)中也有過把系統(tǒng)越改越復(fù)雜的現(xiàn)象，如采用復(fù)雜的控制方式和設(shè)備來實現(xiàn)本可以用簡單裝置來實現(xiàn)的控制，違背了經(jīng)濟、簡單、實用的原則，并可能會增加故障率，這也是要注意的地方。

? ? 隨著工業(yè)設(shè)備自動化控制技術(shù)的發(fā)展，可編程控制器(PLC)在工業(yè)設(shè)備控制中的應(yīng)用越來越廣泛。PLC控制系統(tǒng)的可靠性直接影響到企業(yè)的安全生產(chǎn)和經(jīng)濟運行，系統(tǒng)的抗干擾能力是關(guān)系到整個系統(tǒng)可靠運行的關(guān)鍵。本文詳細(xì)介紹了影響PLC運行的干擾類型及來源，并提出抗干擾設(shè)計的實施策略。

? ? 自動化系統(tǒng)所使用的各種類型PLC中，有的是集中安裝在控制室，有的是安裝在生產(chǎn)現(xiàn)場和各電機設(shè)備上，它們大多處在強電電路和強電設(shè)備所形成的惡劣電磁環(huán)境中。要提高PLC控制系統(tǒng)可靠性，一方面要求PLC生產(chǎn)廠家提高設(shè)備的抗干擾能力，另一方面要求應(yīng)用部門在工程設(shè)計、安裝施工和使用維護(hù)中引起高度重視，多方配合才能完善解決問題，有效地增強系統(tǒng)的抗干擾性能。
