道交通低壓開(kāi)關(guān)柜、環(huán)控電控柜系統(tǒng), 由環(huán)控電控室及中間風(fēng)井配電房?jī)?nèi)的400V環(huán)控Ⅰ、 Ⅱ級(jí)負(fù)荷進(jìn)線雙電源切換柜及饋出柜、Ⅲ級(jí)負(fù)荷單電源進(jìn)線柜及饋出柜、軟起動(dòng)柜、繼電器柜(J屏)等組成.施耐德電氣自動(dòng)化iMCC解決方案在上海地鐵M7環(huán)控電控 iMCC和上海地鐵 M10 環(huán)控電控iMCC中成功應(yīng)用,本文主要將施耐德電氣自動(dòng)化iMCC解決方案在上海地鐵的應(yīng)用作一總結(jié)。
　　網(wǎng)絡(luò)結(jié)構(gòu)
　　綜合單元任務(wù)是將環(huán)控室內(nèi)職能裝置通過(guò)現(xiàn)場(chǎng)總線或工業(yè)以太網(wǎng)連接在一起。綜合單元將相關(guān)的信號(hào)上傳至上一級(jí)系統(tǒng)(EMCS),并將上一級(jí)系統(tǒng)(EMCS)的控制命令轉(zhuǎn)發(fā)給環(huán)控室內(nèi)的智能裝置，以完成整個(gè)環(huán)控室的控制和集成，它主要的硬件設(shè)備平臺(tái)-環(huán)控柜綜合管理系統(tǒng)監(jiān)控主機(jī)(PLC-B)和軟件應(yīng)用平臺(tái)組成。
　　監(jiān)控主機(jī)是各職能設(shè)備與車(chē)站綜合監(jiān)控(EMCS)之間的通訊樞紐，是實(shí)現(xiàn)綜合自動(dòng)化必不可少的設(shè)備，它具有多串口，支持多網(wǎng)絡(luò)、多規(guī)約的要求，具有很好的可擴(kuò)充性和可維護(hù)性。與各個(gè)串口上所連接的智能設(shè)備及各開(kāi)關(guān)量進(jìn)行通訊，同時(shí)與上一級(jí)綜合監(jiān)控系統(tǒng)進(jìn)行數(shù)據(jù)交換，實(shí)現(xiàn)遙測(cè)、遙信和遙控功能。
　　繼電器(J)屏風(fēng)門(mén)、風(fēng)閥類(lèi)設(shè)備控制中使用可編程控制器模塊PLC-A, 主要負(fù)責(zé)對(duì)事故風(fēng)機(jī)組合風(fēng)閥等集中控制，提供柜與綜合監(jiān)控等系統(tǒng)接口端子。PLC-A作為PLC-B同系列的遠(yuǎn)程IO模塊，通過(guò)冗余的雙總線方式與PLC-B連接。即采用遠(yuǎn)程I/O通訊方式，現(xiàn)場(chǎng)執(zhí)行機(jī)構(gòu)、儀器儀表、配電系統(tǒng)等，通過(guò)遠(yuǎn)程I/ O模塊，實(shí)現(xiàn)遠(yuǎn)程控制。
監(jiān)控主機(jī)(PLC-B)
　　綜合管理系統(tǒng)單元采用冗余配置,雙機(jī)熱備系統(tǒng)與Unity Pro 軟件相兼容，并通過(guò)Quantum CPU提供關(guān)鍵過(guò)程應(yīng)用所需要的高度可用性。
　　冗余CPU采用 140CPU67160，它采用Pentium II型芯片，主頻266MHz。 Modbus、Modbus Plus、TCP/IP、USB等多種通訊端口和內(nèi)存卡插槽，內(nèi)存卡最多可擴(kuò)展至16M。集成液晶顯示屏幕，用于顯示系統(tǒng)的運(yùn)行、故障、通訊等狀態(tài)信息。支持鑰匙開(kāi)關(guān)和多種口令保護(hù)，保證系統(tǒng)可靠、穩(wěn)定運(yùn)行;
　　監(jiān)控主機(jī)選用了雙機(jī)熱備系統(tǒng),即兩個(gè)CPU位于兩個(gè)機(jī)架上, 實(shí)現(xiàn)CPU、電源、通訊模塊、擴(kuò)展電纜全部冗余，它們共享一套I/O�；�于 100 Mbps 高速光纖鏈路，用光纖連接兩個(gè)熱備控制器工作時(shí)一臺(tái)CPU為主機(jī)，另一臺(tái)為熱備機(jī)，主備CPU直接通過(guò)光纖連接,如主機(jī)發(fā)生故障或自檢失敗時(shí)可和熱備機(jī)進(jìn)行無(wú)擾切。該切換為硬件切換，非軟件切換，不需編寫(xiě)額外的切換用戶程序。
　　系統(tǒng)結(jié)構(gòu)的中心部分是兩個(gè)Quantum PLC 機(jī)架，即通常意義下的“主機(jī)” 和“備機(jī)”。它們的硬件配置相同( 每個(gè)本地機(jī)架上安裝的模塊必須一致)。每個(gè)機(jī)架配置的核心部件是140 CPU 67160 處理器，專(zhuān)門(mén)設(shè)計(jì)用于Unity Pro 軟件下的雙機(jī)熱備架構(gòu)。該處理器是一個(gè)雙槽模塊，同時(shí)包含中央處理單元和一個(gè)冗余協(xié)處理器。
　　“主” PLC 執(zhí)行應(yīng)用程序并且控制輸入輸出(I/O)�！皞洹� PLC駐留在后臺(tái)，必要的時(shí)候取代“主”P(pán)LC�！皞錂C(jī)”和“主機(jī)”之間通過(guò)一個(gè)集成在 CPU 當(dāng)中的高速光纖鏈路(100Mbps)相連接,以確保主備CPU之間數(shù)據(jù)備份的實(shí)時(shí)性。
