DCS 的維護(hù)可分為：日常維護(hù);預(yù)防性維護(hù)和故障維護(hù)，日常維護(hù)和預(yù)防維護(hù)是在系統(tǒng)未發(fā)生故障所進(jìn)行的維護(hù)。故障維護(hù)發(fā)生在故障產(chǎn)生之后,往往 已造成系統(tǒng)部分功能失靈并對(duì)生產(chǎn)造成不良影響;相反,預(yù)防性維護(hù)是在系統(tǒng)正常運(yùn)行時(shí),對(duì)系統(tǒng)進(jìn)行有計(jì)劃的定期維護(hù),及時(shí)掌握系統(tǒng)運(yùn)行狀態(tài)、消除系統(tǒng)故障隱 患、保證系統(tǒng)長期穩(wěn)定可靠地運(yùn)行,形成定期維護(hù)的概念。實(shí)踐證明,定期維護(hù)能夠有效地防止DCS 突發(fā)故障的產(chǎn)生,形成可觀的間接經(jīng)濟(jì)效益。
　　DCS 系統(tǒng)的日常維護(hù)
　　系統(tǒng)的日常維護(hù)是DCS系統(tǒng)穩(wěn)定高效運(yùn)行的基礎(chǔ)，主要的維護(hù)工作有以下幾點(diǎn)：
　　1) 完善DCS系統(tǒng)管理制度。
　　2) 保證空調(diào)設(shè)備穩(wěn)定運(yùn)行,保證室溫變化小于±5℃/h ,避免由于溫度、濕度急劇變化導(dǎo)致在系統(tǒng)設(shè)備上的凝露。
　　3) 盡量避免電磁場對(duì)系統(tǒng)的干擾,避免移動(dòng)運(yùn)行中的操作站、顯示器等,避免拉動(dòng)或碰傷設(shè)備連接電纜和通訊電纜等。
　　4) 注意防塵，現(xiàn)場與控制室合理隔離，并定時(shí)清掃，保持清潔，防止粉塵對(duì)元件運(yùn)行及散熱產(chǎn)生不良影響;
　　5) 嚴(yán)禁使用非正版軟件和安裝與系統(tǒng)無關(guān)軟件。
　　6) 做好控制子目錄文件的備份,各自控回路的PID 參數(shù)、調(diào)節(jié)器正反作用等系統(tǒng)數(shù)據(jù)記錄工作。
　　7) 檢查控制主機(jī)、顯示器、鼠標(biāo)、鍵盤等硬件是否完好,實(shí)時(shí)監(jiān)控工作是否正常。
　　8) 查看故障診斷畫面,是否有故障提示。
　　預(yù)防維護(hù)
　　有計(jì)劃地進(jìn)行主動(dòng)性、預(yù)防性維護(hù),保證系統(tǒng)運(yùn)行穩(wěn)定可靠。根據(jù)大修周期，利用大修進(jìn)行一次預(yù)防性的維護(hù)，以掌握系統(tǒng)運(yùn)行狀態(tài),消除故障隱患。大修期間對(duì)DCS 系統(tǒng)應(yīng)進(jìn)行徹底、全面的維護(hù)，內(nèi)容包括：
　　1) 系統(tǒng)冗余測試: 對(duì)冗余電源、服務(wù)器、控制器、通訊網(wǎng)絡(luò)進(jìn)行冗余測試。操作站、控制站停電檢修。包括計(jì)算機(jī)內(nèi)部、控制站機(jī)籠、電源箱等部件的灰塵清理。
　　2) 系統(tǒng)供電線路檢修。并對(duì)UPS進(jìn)行供電能力測試和實(shí)施放電操作。
　　3) 接地系統(tǒng)檢修。包括端子檢查、對(duì)接地電阻測試。
　　大修后系統(tǒng)維護(hù)負(fù)責(zé)人應(yīng)確認(rèn)條件具備方可上電，并應(yīng)嚴(yán)格遵照上電步驟進(jìn)行。
