　　2、實時數(shù)據(jù)庫
　　 我公司大型輕烴裝置和設(shè)備已基本實現(xiàn)了自動化,，共有DCS系統(tǒng)5套,，plc系統(tǒng)2套。但是這些系統(tǒng)建設(shè)時間不一,，軟件系統(tǒng)各異,，接口各不相同，系統(tǒng)各自獨立,，妨礙了信息共享利用,。
　　 2001年，我們決定把東營壓氣站大型離心壓縮機(jī)組自動化系統(tǒng)橫河DCS CS1000聯(lián)入局域網(wǎng),，使用OPC方式通過VB,、VC編程實現(xiàn)了在瀏覽器中實時監(jiān)控畫面及其歷史曲線。通過這次嘗試,，我們感到自行編程方式來實現(xiàn)與工業(yè)控制系統(tǒng)的互聯(lián),，達(dá)到從監(jiān)控、報警,、自動報表計算等功能確實有一定難度并且通用性差,，每套系統(tǒng)都照此開發(fā)一套，不僅價格高,，而且隨著生產(chǎn)變動,，系統(tǒng)也可能隨著相應(yīng)改變,，程序也需維護(hù)?？傊?，開發(fā)成本高、移植性差,、擴(kuò)展性差,、維護(hù)成本高并且升級成本與日驟增。
　　 經(jīng)過對當(dāng)前實時數(shù)據(jù)庫調(diào)研分析后,，我們認(rèn)為三維力控實時數(shù)據(jù)庫pSpace,，不論從性能價格比還是軟件易用程度較符合我公司的情況。它具有極強(qiáng)數(shù)據(jù)處理能力的服務(wù)器,，豐富的多數(shù)據(jù)采集接口,、以及功能實用的數(shù)據(jù)查詢分析工具，以pSpace作為整個公司的實時數(shù)據(jù)庫,，向下集成全公司的生產(chǎn)數(shù)據(jù),，橫向可關(guān)系統(tǒng)型數(shù)據(jù)庫（oracle）進(jìn)行雙向數(shù)據(jù)交換，向上為各種生產(chǎn)管理應(yīng)用系統(tǒng)提供平臺支持,，起到了兩個層面之間的橋梁作用使生產(chǎn)過程控制系統(tǒng)和管理信息系統(tǒng)相結(jié)合,，從監(jiān)測和考核原材料及水、電,、汽,、風(fēng)的用量入手，減少能耗物耗,；分析事故原因,，可建立一套由幾個關(guān)鍵參數(shù)組成的關(guān)聯(lián)報警方案，以避免事故的再次發(fā)生,；分析過去的工藝情況,，可查找并消除生產(chǎn)運行瓶頸,，優(yōu)化生產(chǎn)過程,，提高生產(chǎn)運行效率；對比分析操作參數(shù)與運行質(zhì)量的關(guān)系,，可更好地將運行質(zhì)量控制在最恰當(dāng)?shù)姆秶?，最終實現(xiàn)生產(chǎn)企業(yè)管控一體化。
　　
　　3,、實時數(shù)據(jù)庫的設(shè)計
　　 油氣集輸公司下屬單位地理位置分布極為廣泛,，是典型的點多、線長,。為保證數(shù)據(jù)傳輸,，在主要生產(chǎn)站場設(shè)一臺區(qū)域數(shù)據(jù)庫服務(wù)器,，公司中心機(jī)房設(shè)一臺perspace實時數(shù)據(jù)庫服務(wù)器，負(fù)責(zé)實時數(shù)據(jù)的收集,、整理和web發(fā)布,。
　　3.1實時數(shù)據(jù)庫設(shè)計方案

　　3.2 工控內(nèi)部網(wǎng)特點
　　 為保證網(wǎng)絡(luò)安全，設(shè)置力控本地數(shù)據(jù)庫的微機(jī)安裝兩塊網(wǎng)卡,，一塊網(wǎng)卡與管理局的局域網(wǎng)相連接,，一塊網(wǎng)卡與工控的操作站以內(nèi)網(wǎng)方式連接，這臺起到網(wǎng)關(guān)作用的機(jī)器由各站維護(hù)人員及時負(fù)責(zé)升級防病毒軟件和給系統(tǒng)打補(bǔ)丁,，把不安全因素控制在這一端,，避免一些外部因素對操作站的直接沖擊，如果四級單位有多個不同自控系統(tǒng)操作站,，維護(hù)工作主要集中在負(fù)責(zé)上傳數(shù)據(jù)的本地力控機(jī),，把住入口基本上控制了網(wǎng)絡(luò)病毒在內(nèi)部網(wǎng)的侵蝕，并且內(nèi)部其它機(jī)器可通過這臺力控間接從網(wǎng)絡(luò)上下載一些必要程序,，方便了軟件的升級,。
　　
　　3.3 實時數(shù)據(jù)庫采集設(shè)計方案
　　3.3.1當(dāng)DCS具有OPC或DDE接口時，本地實時數(shù)據(jù)庫只需通過以太網(wǎng)就可以以遠(yuǎn)程方式采集DCS數(shù)據(jù),。
　　3.3.2對于PLC,，本地實時數(shù)據(jù)庫需要通過與PLC相匹配的通訊接口采集PLC數(shù)據(jù)。
　　3.3.3對于沒有開放接口的DCS,，本地實時數(shù)據(jù)庫需要通過專用驅(qū)動程序通過相匹配的通訊網(wǎng)絡(luò)采集DCS數(shù)據(jù),。
　　3.3.4對于已經(jīng)實現(xiàn)數(shù)據(jù)采集的裝置，可以通過DDE,、OPC,、ODBC等方式將數(shù)據(jù)直接采集進(jìn)入本地實時數(shù)據(jù)庫。
　　3.3.5 有些實時數(shù)據(jù)進(jìn)行計算處理后,，通過ODBC送到關(guān)系數(shù)據(jù)庫做更深層應(yīng)用,。
　　
　　4、實時數(shù)據(jù)庫在原油庫自動化改造中的應(yīng)用
　　 2002年底,，我們對東營油庫實施了全庫自動化改造,。
　　4.1原油庫自動化改造情況簡介
　　 原油庫自動化改造是公司規(guī)模最大、采集點數(shù)最多的自動化項目,，也公司輸油站庫一次大規(guī)模的自動化,。因其內(nèi)部崗位分散，在內(nèi)部交換數(shù)據(jù)采用工業(yè)以太網(wǎng),，除各崗位有操作站外,，并設(shè)有中心控制室，對整個原油進(jìn)行全面監(jiān)控,。
　　 改造實施內(nèi)容：東營原油庫自動化改造以數(shù)據(jù)采集為重點,，加上部分控制系統(tǒng),，此次實施包括六個重要崗位：流量計崗、罐區(qū)計量崗,、泵房崗,、加熱爐崗、鍋爐崗,、外銷流量計,。
　　根據(jù)情況實際情況，我們選用了德國西門子SIEMENS S7-400自動控制系統(tǒng),。全裝置共有6個控制室：4個現(xiàn)場控制室各設(shè)一個操作員站,，用來監(jiān)控本崗位的工藝過程。中央控制室設(shè)1個操作員站和1個工程師站,，操作員站可以監(jiān)控全裝置的工藝過程,，工程師站除了可以編程組態(tài)外，也可以作為操作員站來使用,。
　　 整個控制系統(tǒng)使用2套冗余的414H控制器,，其中流量計崗和西流量計崗用1套控制器；計量崗和其他三個崗位共用1套控制器,。各崗位的I/O信號模塊安裝在本地的控制柜中,，它們和控制器之間通過PROFIBUS現(xiàn)場總線相連接。其系統(tǒng)結(jié)構(gòu)圖如圖1所示：

　　 怎樣通過局域網(wǎng),，對現(xiàn)場過程,、歷史曲線等應(yīng)用遠(yuǎn)程瀏覽是此次自動化改造面臨的新問題。西門子的組態(tài)軟件WINCC具有直接發(fā)布功能,，現(xiàn)場施工的工程技術(shù)人員更傾向于使用WINCC自帶的WEB發(fā)布功能即從操作站上把現(xiàn)有組態(tài)畫面網(wǎng)上直接發(fā)布,他們認(rèn)為不但所有組態(tài)可以原樣保留,，不增加工作量，可通過權(quán)限來控制,，但我們卻認(rèn)為如果這樣實施首先帶來的安全問題不容忽視,；其次是針對性不強(qiáng)，因網(wǎng)上瀏覽以管理技術(shù)人員為主,，一些詳細(xì)的操作畫面完全沒有必要,，如方便操作員的所有控制組畫面，本地發(fā)布,，數(shù)據(jù)不統(tǒng)一存儲,，將會造成全公司自控化系統(tǒng)發(fā)布不統(tǒng)一,，不但難于管理,，維護(hù)難度增加，而且更深層次的應(yīng)用如優(yōu)化運行,、故障分析等無法展開,。力控實時數(shù)據(jù)庫pSpace解決方案的整體引入即建立原油庫本地二級實時數(shù)據(jù)存儲,，公司建立一級實時數(shù)據(jù)發(fā)布、存儲中心,。初始我們采用step7 opc server方式向pSpace傳送數(shù)據(jù),，使用一個階段后，我們改為采用通過在力控中配置I/O驅(qū)動中softnets7來直接從工業(yè)以太網(wǎng)上讀I/O設(shè)備,，力控當(dāng)作為成plc系統(tǒng)的一個的操作站,，某些轉(zhuǎn)換用pSpace的腳本完全可實現(xiàn)，完全能夠更快更迅速地采集西門子 PLC的數(shù)據(jù),，同時實時地向設(shè)在公司的中心服務(wù)器傳輸數(shù)據(jù),。
　　 設(shè)在中控室的力控上傳局域網(wǎng)的監(jiān)控機(jī)器既在原油庫內(nèi)部的工業(yè)以太網(wǎng)上，同時又在局域網(wǎng)上,，完全起到網(wǎng)關(guān)的作用,，它有選擇性進(jìn)行組態(tài)顯示原油庫各采集點的重要參數(shù)，控制點沒有進(jìn)行組態(tài),，從源頭上保證數(shù)據(jù)的安全性,。原油庫西門子S7-400實時數(shù)據(jù)上傳局域網(wǎng)解決方案的成功實施，我公司全面實施自控系統(tǒng)遠(yuǎn)程監(jiān)控開做了嘗試,，它集成了大量的生產(chǎn)實時數(shù)據(jù),，打破了過去生產(chǎn)實時數(shù)據(jù)停留在各崗位的局限，實現(xiàn)了全公司生產(chǎn)實時數(shù)據(jù)的共享,。有了它,，生產(chǎn)調(diào)度可以及時全面了解生產(chǎn)情況，迅速處理種種突發(fā)事件,。今后集輸公司現(xiàn)有各生產(chǎn)崗位的重要實時參數(shù),，可統(tǒng)一存儲和管理，并可保存幾年的歷史數(shù)據(jù),，通過對連續(xù)生產(chǎn)中存在著大量的實時數(shù)據(jù)處理,、存儲和集成建立歷史數(shù)據(jù)曲線、報警查詢,、異常報警,、控制點監(jiān)視、事故追憶等應(yīng)用,。遠(yuǎn)程監(jiān)測關(guān)鍵參數(shù)運行狀態(tài),，使生產(chǎn)的運行狀態(tài)保持平穩(wěn)，提高操作水平,。
　　 中心實時庫建立所需的數(shù)據(jù)源,，使用server、client應(yīng)答與遠(yuǎn)端區(qū)域數(shù)據(jù)庫進(jìn)行交互。
