該自動(dòng)控制系統(tǒng)由外方設(shè)計(jì)，限于當(dāng)時(shí)的技術(shù)，其信息為系統(tǒng)專用，不能與廠級(jí)局域網(wǎng)（以太網(wǎng)）實(shí)現(xiàn)信息共享，無法實(shí)現(xiàn)工業(yè)數(shù)據(jù)的遠(yuǎn)程訪問，對(duì)生產(chǎn)、指揮和調(diào)度帶來不便。 雖然現(xiàn)在一些工控設(shè)備已出現(xiàn)以太網(wǎng)接口，但是對(duì)已經(jīng)建立了完整專用工業(yè)網(wǎng)絡(luò)的工業(yè)企業(yè)來說，特別是當(dāng)這些工業(yè)網(wǎng)還運(yùn)行在DOS平臺(tái)上，更新設(shè)備的軟硬件成本高昂。本設(shè)計(jì)針對(duì)南京自來水公司浦口水廠自動(dòng)控制系統(tǒng)，在不改變?cè)泄I(yè)網(wǎng)絡(luò)的情況下，將建立在DOS平臺(tái)上的專用工業(yè)網(wǎng)上的數(shù)據(jù)傳輸?shù)揭蕴W(wǎng)上發(fā)布。 2. 系統(tǒng)設(shè)計(jì) 2.1. 設(shè)計(jì)目標(biāo)和要求 ?。?） 設(shè)計(jì)目標(biāo)：數(shù)據(jù)從DOS工作站（上位機(jī)）傳輸?shù)絅T服務(wù)器，存入數(shù)據(jù)庫(kù);數(shù)據(jù)庫(kù)實(shí)現(xiàn)自動(dòng)維護(hù);將數(shù)據(jù)發(fā)布在Web頁面上。 ?。?） 實(shí)時(shí)性：NT服務(wù)器能夠及時(shí)獲取工業(yè)數(shù)據(jù)，并能及時(shí)在Web上發(fā)布。 ?。?） 容錯(cuò)性：在數(shù)據(jù)傳輸中能夠及時(shí)發(fā)現(xiàn)并丟棄錯(cuò)誤的數(shù)據(jù)。 ?。?） 穩(wěn)定性：在ELIN-BUS網(wǎng)絡(luò)上的DOS工作站能夠及時(shí)準(zhǔn)確地提供數(shù)據(jù)，并保證其原有數(shù)據(jù)監(jiān)控功能不受影響。NT服務(wù)器端系統(tǒng)能長(zhǎng)時(shí)間（72小時(shí)）連續(xù)正常工作。 （5） 數(shù)據(jù)存儲(chǔ)查詢：數(shù)據(jù)庫(kù)存儲(chǔ)一年內(nèi)每天的詳細(xì)數(shù)據(jù)，永久存儲(chǔ)每日平均數(shù)據(jù)。能夠繪出任意時(shí)間段任意一項(xiàng)工業(yè)數(shù)據(jù)的變化曲線圖。 2.2. 系統(tǒng)構(gòu)架 工業(yè)設(shè)備通過ELIN-BUS網(wǎng)絡(luò)將工業(yè)數(shù)據(jù)傳輸?shù)紻OS監(jiān)控工作站，由于ELIN-BUS網(wǎng)絡(luò)與以太網(wǎng)完全不兼容，為了實(shí)現(xiàn)不同網(wǎng)絡(luò)間的數(shù)據(jù)通訊，使用串口線連接ELIN-BUS網(wǎng)絡(luò)中的一臺(tái)DOS工作站和以太網(wǎng)中的一臺(tái)NT服務(wù)器，再通過NT服務(wù)器將數(shù)據(jù)在以太網(wǎng)上共享。 [align=center]
圖2.1 系統(tǒng)總體結(jié)構(gòu)圖[/align] 2.3. DOS工作站端設(shè)計(jì) 在DOS工作站中植入一套數(shù)據(jù)發(fā)送程序，工作站啟動(dòng)后，該程序駐留內(nèi)存。廠方原有組態(tài)軟件沒有對(duì)外數(shù)據(jù)接口，所以在組態(tài)軟件設(shè)計(jì)中，定時(shí)切換至數(shù)據(jù)屏幕，并調(diào)用數(shù)據(jù)發(fā)送程序。數(shù)據(jù)發(fā)送程序讀取DOS的屏幕顯示緩沖區(qū)，發(fā)送一頁屏幕數(shù)據(jù)。數(shù)據(jù)約每?jī)煞昼姲l(fā)送一次。 2.4. NT服務(wù)器端設(shè)計(jì) NT服務(wù)器端建立一套程序，其功能為：數(shù)據(jù)接收、數(shù)據(jù)分析存儲(chǔ)、數(shù)據(jù)整理、數(shù)據(jù)查詢、Web瀏覽、輔助工具。 數(shù)據(jù)從串口讀入，存入Microsoft SQL Server數(shù)據(jù)庫(kù)。程序通過ADO（Microsoft ActiveX Data Object）連接ODBC（Open Database Connectivity）訪問SQL數(shù)據(jù)庫(kù)。每日凌晨，程序自動(dòng)對(duì)前一天的數(shù)據(jù)進(jìn)行維護(hù)，刪除過期數(shù)據(jù)。 服務(wù)器使用IIS（Internet Inbation Service）提供Web服務(wù)，在ASP（Active Server Page）中訪問數(shù)據(jù)庫(kù)，并通過圖表組件，使用戶可以在網(wǎng)頁上瀏覽到數(shù)據(jù)和數(shù)據(jù)圖表。 NT服務(wù)器端系統(tǒng)結(jié)構(gòu)分為三部分：數(shù)據(jù)庫(kù)層，包括數(shù)據(jù)庫(kù)（SQL Server）和數(shù)據(jù)訪問組件（ODBC、ADO）;中間層，由若干個(gè)COM對(duì)象組成，包括數(shù)據(jù)庫(kù)訪問對(duì)象、串口通訊對(duì)象和圖表控件。應(yīng)用層，包括數(shù)據(jù)接收程序界面和Web應(yīng)用程序。應(yīng)用層通過捆綁中間層組件來實(shí)現(xiàn)系統(tǒng)主要功能。
