DCS系統(tǒng)配置
1. 系統(tǒng)配置的工作內(nèi)容
DCS的發(fā)展使系統(tǒng)配置的適應(yīng)性越來越強(qiáng),而且也囊括了PLC控制功能,從幾個、十幾個回路的小系統(tǒng)到幾百個、幾千個回路的大系統(tǒng)都可以實現(xiàn)。系統(tǒng)配置的原則應(yīng)是在滿足裝置生產(chǎn)和控制要求的前提下盡量減少硬件的數(shù)量,以求經(jīng)濟(jì)合理,并留有恰當(dāng)?shù)挠嗔?。系統(tǒng)配置工作主要包括以下幾個方面。
(1) 系統(tǒng)I/O點統(tǒng)計:一般包括10-15%的備用量。要分別考慮熱備用和冷備用的情況。
(2) 控制站:凡是參與控制的變量或重要的監(jiān)視變量,考慮進(jìn)入控制站。I/O卡件種類和數(shù)量按I/O點統(tǒng)計表的數(shù)量確定。機(jī)柜具有10%的備用空間。主控單元冗余配置、內(nèi)部網(wǎng)絡(luò)冗余配置、控制I/O卡冗余配置,電源冗余配置,按1秒的標(biāo)準(zhǔn)掃描周期估計系統(tǒng)負(fù)荷滿足DCS具體要求,考慮現(xiàn)場變送器供電制式與DCS的關(guān)聯(lián)。
(3) 監(jiān)視站:對于有監(jiān)視站的系統(tǒng),可以考慮一些僅需要監(jiān)視的點數(shù)到監(jiān)控站中。但監(jiān)視站一般不是冗余配置。
(4) 操作站:根據(jù)工藝流程工段或區(qū)域的劃分和中控室內(nèi)操作人員數(shù)確定操作站的臺數(shù)。zui低限度要配兩臺帶電腦設(shè)備的主操作站,打印機(jī)的臺數(shù)應(yīng)滿足報警、報表及拷貝的需要,但報警和報表用的打印機(jī)必須分開。
(5) 輔助操作臺的配置:安裝閃光報警器、指示儀、手操器、開關(guān)按鈕、指示燈、端子排、空開、等。
(6) 其他站或模件的配置:根據(jù)不同系統(tǒng)的結(jié)構(gòu)及功能需要,可配置工程師站、大屏幕、上位機(jī)等。
(7) 通信系統(tǒng)配置:凡是與通信有關(guān)的網(wǎng)卡、網(wǎng)線(總線)、交換機(jī)、耦合器、調(diào)制解調(diào)器等應(yīng)根據(jù)需要考慮冗余配置。
(8) 系統(tǒng)電源和輔助機(jī)柜配置(安全柵柜、端子柜、繼電器柜、配電箱等):UPS不間斷電源容量比DCS系統(tǒng)所需容量高40%,并保證電網(wǎng)停電時能繼續(xù)供電30分鐘。按現(xiàn)場危險場所劃分,*安全柵型號。
(9) 備品備件和消耗品,原則上要備足兩年的用量、
