 一、概述
   中國(guó)石油大慶石化公司,是中國(guó)石油天然氣股份有限公司直屬的地區(qū)分公司,從事煉油、化工、化肥、化纖生產(chǎn)的特大型石油化工聯(lián)合企業(yè)。現(xiàn)有6個(gè)生產(chǎn)廠,2 個(gè)輔助生產(chǎn)廠。公司擁有生產(chǎn)裝置131套,年原油加工能力600萬(wàn)噸,年產(chǎn)乙烯48萬(wàn)噸,聚乙烯36萬(wàn)噸,腈綸纖維6萬(wàn)噸,合成氨33萬(wàn)噸,尿素56萬(wàn) 噸,可生產(chǎn)60種151個(gè)牌號(hào)的石油化工產(chǎn)品。大慶石化公司的前身大慶石油化工總廠,是我國(guó)較早的石油化工企業(yè)之一,也是我國(guó)重要的石油化工基地。大慶 石化公司在緊抓生產(chǎn)建設(shè)的同時(shí),也非常注重信息化建設(shè)。
   全球信息技術(shù)飛速發(fā)展,尤其是因特網(wǎng)的出現(xiàn)和應(yīng)用的普及,使得信息技術(shù)得以迅速滲透到 經(jīng)濟(jì)社會(huì)的各個(gè)領(lǐng)域,標(biāo)志著人類進(jìn)入了信息化時(shí)代。信息資源已成為與材料和能源同等重要的戰(zhàn)略資源;信息技術(shù)正以其廣泛的滲透性和無(wú)與倫比的先進(jìn)性與傳統(tǒng) 產(chǎn)業(yè)結(jié)合;信息產(chǎn)業(yè)已發(fā)展為世界范圍內(nèi)的朝陽(yáng)產(chǎn)業(yè)和新的經(jīng)濟(jì)增長(zhǎng)點(diǎn);信息化水平已經(jīng)成為現(xiàn)代化企業(yè)水平和綜合實(shí)力的重要標(biāo)志。大慶石化公司經(jīng)過(guò)多年的努 力,在信息化建設(shè)中已取得了很大進(jìn)步,如辦公自動(dòng)化,電子商務(wù)。尤其是生產(chǎn)過(guò)程自動(dòng)化,經(jīng)過(guò)多年努力,大慶石化公司全面實(shí)現(xiàn)了DCS自動(dòng)化改造。但是在實(shí) 現(xiàn)全廠信息化建設(shè)之前,還存在如下問(wèn)題:
   1)生產(chǎn)數(shù)據(jù)沒(méi)有有效共享,因而對(duì)影響生產(chǎn)過(guò)程的主要因素缺乏有效的監(jiān)控手段。雖然公司的主要生產(chǎn)裝 置都安裝了DCS,但絕大部分裝置的數(shù)據(jù)只能顯示在裝置的操作站上,而沒(méi)有采集到公司或分廠的辦公系統(tǒng)中。這樣我們只有到各生產(chǎn)裝置的控制室,才能觀察到 生產(chǎn)數(shù)據(jù),在分廠的調(diào)度室,辦公室,或公司領(lǐng)導(dǎo),都無(wú)法直接看到現(xiàn)場(chǎng)的生產(chǎn)數(shù)據(jù)。如果出差在外,想了解一下生產(chǎn)情況就更是無(wú)能為力了。在當(dāng)今互聯(lián)網(wǎng)把大千 世界聯(lián)在一起的今天,不能不說(shuō)是一種遺憾!
   2)分散的“信息孤島”無(wú)法進(jìn)行集中化管理。由于各裝置信息封閉,即使在同一分廠,由于采用的是不 同廠家,或同一廠家不同型號(hào)的DCS,彼此間沒(méi)有數(shù)據(jù)通訊手段。這致使生產(chǎn)管理的各個(gè)環(huán)節(jié)脫節(jié),生產(chǎn)管理部門(mén)不能及時(shí)、有效地了解生產(chǎn)狀況,指導(dǎo)組織生 產(chǎn),造成了一定的浪費(fèi)。
   3)沒(méi)有長(zhǎng)期的歷史數(shù)據(jù)存儲(chǔ)。隨著存儲(chǔ)介質(zhì)價(jià)格不斷下降,保存海量歷史數(shù)據(jù)不但是必要的,而且是現(xiàn)實(shí)的。而DCS本身的歷史數(shù)據(jù)存儲(chǔ)能力一般都比較有限,而長(zhǎng)期的歷史數(shù)據(jù)有助于事故診斷。
   4)質(zhì)量信息反饋滯后,導(dǎo)致加工成本增加?;?yàn)數(shù)據(jù)直接反映生產(chǎn)的質(zhì)量情況,對(duì)指導(dǎo)生產(chǎn)具有非常重要的意義。先前這些數(shù)據(jù)主要通過(guò)手工報(bào)表形式報(bào)送生產(chǎn) 管理部門(mén),造成信息遲滯,并且不利于對(duì)比分析。因此及時(shí)準(zhǔn)確地將質(zhì)量數(shù)據(jù)反饋給裝置操作人員和生產(chǎn)調(diào)度人員,可以保證有效地控制生產(chǎn)質(zhì)量、降低生產(chǎn)成本。
   5)無(wú)法實(shí)現(xiàn)全廠信息瀏覽。如何讓公司領(lǐng)導(dǎo)用統(tǒng)一平臺(tái)直觀的看到各分廠的生產(chǎn)報(bào)表,統(tǒng)計(jì)數(shù)據(jù),對(duì)于領(lǐng)導(dǎo)決策非常重要。
   通過(guò)上面的分析,我們不難看出,如何將分散的“信息孤島”有效地連接起來(lái),實(shí)行網(wǎng)絡(luò)化、集中化,將生產(chǎn)過(guò)程數(shù)據(jù)與生產(chǎn)管理系統(tǒng)有機(jī)連接起來(lái);把生產(chǎn)過(guò)程 信息、原料消耗、過(guò)程產(chǎn)品產(chǎn)量、產(chǎn)品產(chǎn)量、能源消耗、設(shè)備狀態(tài)等科學(xué)地分類,提供給管理層數(shù)據(jù)庫(kù),從而減少人工操作,提高管理層數(shù)據(jù)庫(kù)的準(zhǔn)確性,提高公司 的控制力和控制質(zhì)量。同時(shí)也能夠使企業(yè)的先進(jìn)控制、優(yōu)化計(jì)算,流程模擬等更加方便。
  
   二、實(shí)施方案
   公司信息化內(nèi)容很多,如裝置達(dá)標(biāo),LIMS,質(zhì)量統(tǒng)計(jì),價(jià)格管理,成本核算,生產(chǎn)信息化。其中生產(chǎn)信息化是整個(gè)系統(tǒng)的基礎(chǔ),由于篇幅的限制,這里著重對(duì)其進(jìn)行介紹。

   三、數(shù)采方案
   1、概述
   數(shù)據(jù)采集是實(shí)時(shí)數(shù)據(jù)庫(kù)的重要組成部分,它負(fù)責(zé)將現(xiàn)場(chǎng)數(shù)據(jù)實(shí)時(shí)傳送給數(shù)據(jù)庫(kù),將操作數(shù)據(jù)下送到現(xiàn)場(chǎng),是數(shù)據(jù)庫(kù)服務(wù)器與生產(chǎn)控制系統(tǒng)連接的橋梁。如果沒(méi)有穩(wěn)定、高效、豐富的數(shù)采接口,實(shí)時(shí)數(shù)據(jù)庫(kù)只能是空中樓閣。
   紫金橋軟件具有豐富的I/O接口,能夠與各種DCS,PLC,智能儀表通過(guò)多種連接方式,如以太網(wǎng)、串口、撥號(hào)等。并支持DDE、OPC、設(shè)備專有通信協(xié)議等。同一數(shù)據(jù)庫(kù)可以同時(shí)與任意多種驅(qū)動(dòng)程序進(jìn)行通訊。下圖為數(shù)采結(jié)構(gòu)圖。

  數(shù)采結(jié)構(gòu)圖

  
   圖中的I/O驅(qū)動(dòng)就是各種數(shù)采接口。
   本項(xiàng)目的關(guān)鍵是實(shí)現(xiàn)各分廠生產(chǎn)裝置的數(shù)據(jù)采集。由于大慶石化公司分廠很多,自控裝置種類繁多,有大量的DCS、PLC、智能表等。通信方式多種多樣。如有的通過(guò)OPC,有的通過(guò)DDE,有的是廠家專有協(xié)議;網(wǎng)絡(luò)連接方式也很多,如以太網(wǎng)、串口、現(xiàn)場(chǎng)總線等。
   2、關(guān)鍵問(wèn)題
   辦公網(wǎng)控制網(wǎng)隔離
   保證自控裝置的安全是致關(guān)重要的。為了保證控制網(wǎng)的獨(dú)立性,辦公網(wǎng)與控制網(wǎng)間是完全隔離的。實(shí)時(shí)數(shù)據(jù)庫(kù)運(yùn)行在辦公網(wǎng)一側(cè),為了安全的與控制設(shè)備通信,我們采取了多種措施。
   1)在控制網(wǎng)與辦公網(wǎng)分別設(shè)置數(shù)采機(jī),數(shù)采機(jī)間通過(guò)串口相連,這樣能夠有效的防止網(wǎng)絡(luò)病毒侵入。

   為了提高串口的通信速度可以將兩臺(tái)前置數(shù)采機(jī)器放的很近,這樣可以將串口通信速度設(shè)的很高如112K。對(duì)于較遠(yuǎn)的可以采用485方式通信。
   2)機(jī)器配置兩塊網(wǎng)卡,一塊網(wǎng)卡與控制網(wǎng)相連,一塊與辦公網(wǎng)相連,而且兩塊網(wǎng)卡處于不同網(wǎng)段。除了數(shù)據(jù)通信用到的端口號(hào),其余通信端口都禁止掉。并且裝好防火墻,保持防病毒軟件及時(shí)自動(dòng)更新。

   3)數(shù)據(jù)集中到VAX/ALPHA機(jī),以VAX/ALPHA為橋梁實(shí)現(xiàn)辦公網(wǎng)與控制網(wǎng)相連。VAX/ALPHA運(yùn)行的是VMS操作系統(tǒng),安全性較高。并且很多裝置的上位機(jī)是VAX/ALPHA,所以通過(guò)VAX/ALPHA為中轉(zhuǎn),是比較方便的。
   斷線數(shù)據(jù)自動(dòng)恢復(fù)
   由于大慶石化公司裝置很多,距離較遠(yuǎn),再加上現(xiàn)場(chǎng)干擾多,所以網(wǎng)絡(luò)通信并不是十分可靠,網(wǎng)絡(luò)故障時(shí)而發(fā)生。紫金橋?qū)崟r(shí)數(shù)據(jù)庫(kù)具有斷線后數(shù)據(jù)自動(dòng)恢復(fù)功 能,即當(dāng)網(wǎng)絡(luò)出現(xiàn)故障時(shí),前端數(shù)采機(jī)能夠自動(dòng)將數(shù)據(jù)保存起來(lái),當(dāng)網(wǎng)絡(luò)恢復(fù)時(shí)將歷史數(shù)據(jù)插入到遠(yuǎn)程實(shí)時(shí)數(shù)據(jù)庫(kù)。利用該功能,就不必?fù)?dān)心歷史數(shù)據(jù)缺失了。

   為化驗(yàn)人員提供化驗(yàn)數(shù)據(jù)計(jì)算處理和錄入界面,以便將生產(chǎn)化驗(yàn)數(shù)據(jù)收集到實(shí)時(shí)數(shù)據(jù)庫(kù)。紫金橋?qū)崟r(shí)數(shù)據(jù)庫(kù)有專門(mén)的人工錄入記錄點(diǎn)和操作界面,能夠保證用戶在合理的時(shí)間范圍內(nèi)錄入數(shù)據(jù),并將數(shù)據(jù)按照填寫(xiě)的時(shí)間插入到歷史數(shù)據(jù)庫(kù)中。對(duì)于超期沒(méi)有錄入的數(shù)據(jù)給出報(bào)警。
   四、生產(chǎn)管理信息系統(tǒng)帶來(lái)的好處
   1)及時(shí)了解生產(chǎn)動(dòng)態(tài)。分廠級(jí)管理人員隨時(shí)了解生產(chǎn)裝置、公用工程運(yùn)行狀況,包括監(jiān)控點(diǎn)的溫度、壓力、流量等實(shí)時(shí)數(shù)據(jù);物料和能源動(dòng)力消耗數(shù)據(jù)、產(chǎn)品產(chǎn)量和質(zhì)量數(shù)據(jù)。各級(jí)人員及時(shí)準(zhǔn)確掌握生產(chǎn)動(dòng)態(tài),對(duì)生產(chǎn)過(guò)程中出現(xiàn)的問(wèn)題及時(shí)做出處理,以保證生產(chǎn)安穩(wěn)運(yùn)行。
   2)實(shí)時(shí)數(shù)據(jù)庫(kù)作為控制系統(tǒng)和上層管理系統(tǒng)的中間層,起到承上啟下的作用。其將各控制系統(tǒng)的數(shù)據(jù)集中起來(lái),以統(tǒng)一的形式存放,實(shí)現(xiàn)了有效的數(shù)據(jù)共享。由 于實(shí)時(shí)數(shù)據(jù)庫(kù)支持各種開(kāi)放接口,如OPC、DDE、OLE等,因此保存在實(shí)時(shí)數(shù)據(jù)庫(kù)中的數(shù)據(jù)可直接為先進(jìn)控制、優(yōu)化控制、流程模擬的數(shù)據(jù)源。另外、也可以 將與上層管理系統(tǒng)相關(guān)的數(shù)據(jù),轉(zhuǎn)儲(chǔ)到關(guān)系數(shù)據(jù)庫(kù)中,以實(shí)現(xiàn)高層次的生產(chǎn)記錄管理。
   3)實(shí)現(xiàn)長(zhǎng)期歷史存儲(chǔ)。一般DCS中歷史數(shù)據(jù)保存時(shí)間較短, 尤其是早期投用的DCS,外存較小,無(wú)法長(zhǎng)期保存大量的,快速變化的歷史數(shù)據(jù)。而通用的實(shí)時(shí)數(shù)據(jù)庫(kù)具有高效的存儲(chǔ)策略,再加上廉價(jià)的大容量的存儲(chǔ)介質(zhì),可 以將重要的生產(chǎn)參數(shù)長(zhǎng)期保存,現(xiàn)在各裝置歷史數(shù)據(jù)可以保存10年。
   4)提供多種數(shù)據(jù)查詢、分析手段。通過(guò)查詢工具可以快速查詢生產(chǎn)實(shí)時(shí)數(shù)據(jù)、歷史數(shù)據(jù);分析工具可以對(duì)產(chǎn)品的生產(chǎn)質(zhì)量進(jìn)行評(píng)定,給管理者決策提供幫助;統(tǒng)計(jì)工具,可以對(duì)數(shù)據(jù)進(jìn)行橫向比較,也可以對(duì)數(shù)據(jù)的歷史情況進(jìn)行分析。
   5)與桌面工具集成??梢詫⑸a(chǎn)數(shù)據(jù)引入辦公軟件,如Excel,Word等,可利用辦公軟件的圖表、分析工具對(duì)生產(chǎn)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)、分析、報(bào)表等。
   6)實(shí)現(xiàn)了Web瀏覽。無(wú)論何時(shí)何地,只要有互聯(lián)網(wǎng),就可以隨時(shí)查看各裝置的實(shí)時(shí)生產(chǎn)數(shù)據(jù),歷史趨勢(shì),統(tǒng)計(jì)報(bào)表等。而且在機(jī)器中不必預(yù)先安裝實(shí)時(shí)數(shù)據(jù)庫(kù)軟件。
   7)通過(guò)數(shù)據(jù)庫(kù)瀏覽器,可以對(duì)分廠的數(shù)據(jù)、報(bào)表、流程圖、趨勢(shì)進(jìn)行查看。只要分廠的數(shù)據(jù)庫(kù)是開(kāi)放的,有權(quán)限的用戶都可以訪問(wèn),并且無(wú)需將組態(tài)內(nèi)容復(fù)制到本地,紫金橋數(shù)據(jù)庫(kù)具有自動(dòng)搜索功能,能夠自動(dòng)找到網(wǎng)內(nèi)的所有實(shí)時(shí)數(shù)據(jù)庫(kù)。
   8)只要權(quán)限允許,可以在客戶端瀏覽數(shù)據(jù)的同時(shí),在線修改點(diǎn)組態(tài)、畫(huà)面、報(bào)表、趨勢(shì),并能上傳到實(shí)時(shí)數(shù)據(jù)庫(kù)。
   五.結(jié)論
   通過(guò)信息系統(tǒng)的集成,實(shí)現(xiàn)整個(gè)公司作為一個(gè)整體意義上的信息系統(tǒng),使得各個(gè)分公司實(shí)現(xiàn)信息共享,減少重復(fù)工作,打破信息孤島現(xiàn)象,提高了工作效率。
   紫金橋?qū)崟r(shí)數(shù)據(jù)庫(kù)自投用以來(lái),運(yùn)行穩(wěn)定,采集速度快,歷史保存時(shí)間長(zhǎng),是信息化建設(shè)中的好幫手。
