1.3 FCS
(1)FCS是第五代過程控制系統(tǒng),它是21世紀(jì)自動(dòng)化控制系統(tǒng)的方向。是3C技術(shù)(Communication,Computer,Control)的融合?;救蝿?wù)是:本質(zhì)(本征)安全、危險(xiǎn)區(qū)域、易變過程、難于對(duì)付的非常環(huán)境。
?。?)全數(shù)字化、智能、多功能取代模擬式單功能儀器、儀表、控制裝置。
?。?)用兩根線聯(lián)接分散的現(xiàn)場儀表、控制裝置,取代每臺(tái)儀表的兩根線。“現(xiàn)場控制”取代“分散控制”;數(shù)據(jù)的傳輸采用“總線”方式。
?。?)從控制室到現(xiàn)場設(shè)備的雙向數(shù)字通信總線,是互聯(lián)的、雙向的、串行多節(jié)點(diǎn)、開放的數(shù)字通信系統(tǒng)取代單向的、單點(diǎn)、并行、封閉的模擬系統(tǒng)。
?。?)用分散的虛擬控制站取代集中的控制站。
?。?)把微機(jī)處理器轉(zhuǎn)入現(xiàn)場自控設(shè)備,使設(shè)備具有數(shù)字計(jì)算和數(shù)字通信能力,信號(hào)傳輸精度高,遠(yuǎn)程傳輸。實(shí)現(xiàn)信號(hào)傳輸全數(shù)字化、控制功能分散、標(biāo)準(zhǔn)統(tǒng)一全開放。
?。?)可上局域網(wǎng),再可與internet相通。既是通信網(wǎng)絡(luò),又是控制網(wǎng)絡(luò)。
?。?)3類FCS的典型應(yīng)用:1) 連續(xù)的工藝過程自動(dòng)控制如石油化工,其中“本安防爆”技術(shù)是重要的;2)分立的工藝動(dòng)作自動(dòng)控制如汽車制造機(jī)器人、汽車;3)多點(diǎn)控制如樓宇自動(dòng)化。
這三大控制系統(tǒng),尤其是DCS、PLC,都在電站得到了廣泛應(yīng)用,而且效果也非常好。
