道交通低壓開關(guān)柜、環(huán)控電控柜系統(tǒng), 由環(huán)控電控室及中間風井配電房內(nèi)的400V環(huán)控Ⅰ、 Ⅱ級負荷進線雙電源切換柜及饋出柜、Ⅲ級負荷單電源進線柜及饋出柜、軟起動柜、繼電器柜(J屏)等組成.施耐德電氣自動化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中成功應用,本文主要將施耐德電氣自動化iMCC解決方案在上海地鐵的應用作一總結(jié)。
　　網(wǎng)絡(luò)結(jié)構(gòu)
　　綜合單元任務(wù)是將環(huán)控室內(nèi)職能裝置通過現(xiàn)場總線或工業(yè)以太網(wǎng)連接在一起。綜合單元將相關(guān)的信號上傳至上一級系統(tǒng)(EMCS),并將上一級系統(tǒng)(EMCS)的控制命令轉(zhuǎn)發(fā)給環(huán)控室內(nèi)的智能裝置，以完成整個環(huán)控室的控制和集成，它主要的硬件設(shè)備平臺-環(huán)控柜綜合管理系統(tǒng)監(jiān)控主機(PLC-B)和軟件應用平臺組成。
　　監(jiān)控主機是各職能設(shè)備與車站綜合監(jiān)控(EMCS)之間的通訊樞紐，是實現(xiàn)綜合自動化必不可少的設(shè)備，它具有多串口，支持多網(wǎng)絡(luò)、多規(guī)約的要求，具有很好的可擴充性和可維護性。與各個串口上所連接的智能設(shè)備及各開關(guān)量進行通訊，同時與上一級綜合監(jiān)控系統(tǒng)進行數(shù)據(jù)交換，實現(xiàn)遙測、遙信和遙控功能。
　　繼電器(J)屏風門、風閥類設(shè)備控制中使用可編程控制器模塊PLC-A, 主要負責對事故風機組合風閥等集中控制，提供柜與綜合監(jiān)控等系統(tǒng)接口端子。PLC-A作為PLC-B同系列的遠程IO模塊，通過冗余的雙總線方式與PLC-B連接。即采用遠程I/O通訊方式，現(xiàn)場執(zhí)行機構(gòu)、儀器儀表、配電系統(tǒng)等，通過遠程I/ O模塊，實現(xiàn)遠程控制。
監(jiān)控主機(PLC-B)
　　綜合管理系統(tǒng)單元采用冗余配置,雙機熱備系統(tǒng)與Unity Pro 軟件相兼容，并通過Quantum CPU提供關(guān)鍵過程應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)存卡最多可擴展至16M。集成液晶顯示屏幕，用于顯示系統(tǒng)的運行、故障、通訊等狀態(tài)信息。支持鑰匙開關(guān)和多種口令保護，保證系統(tǒng)可靠、穩(wěn)定運行;
　　監(jiān)控主機選用了雙機熱備系統(tǒng),即兩個CPU位于兩個機架上, 實現(xiàn)CPU、電源、通訊模塊、擴展電纜全部冗余，它們共享一套I/O。基于 100 Mbps 高速光纖鏈路，用光纖連接兩個熱備控制器工作時一臺CPU為主機，另一臺為熱備機，主備CPU直接通過光纖連接,如主機發(fā)生故障或自檢失敗時可和熱備機進行無擾切。該切換為硬件切換，非軟件切換，不需編寫額外的切換用戶程序。
　　系統(tǒng)結(jié)構(gòu)的中心部分是兩個Quantum PLC 機架，即通常意義下的“主機” 和“備機”。它們的硬件配置相同( 每個本地機架上安裝的模塊必須一致)。每個機架配置的核心部件是140 CPU 67160 處理器，專門設(shè)計用于Unity Pro 軟件下的雙機熱備架構(gòu)。該處理器是一個雙槽模塊，同時包含中央處理單元和一個冗余協(xié)處理器。
　　“主” PLC 執(zhí)行應用程序并且控制輸入輸出(I/O)。“備” PLC駐留在后臺，必要的時候取代“主”PLC?！皞錂C”和“主機”之間通過一個集成在 CPU 當中的高速光纖鏈路(100Mbps)相連接,以確保主備CPU之間數(shù)據(jù)備份的實時性。
