因保證不出現(xiàn)誤操作事故,還增加了相當(dāng)部分的判據(jù)條件和I/0測點(diǎn),這種方式的優(yōu)點(diǎn)是當(dāng)一臺(tái)機(jī)組停運(yùn)或檢修,可以較方便地對DCS進(jìn)行檢查,同時(shí)也增大了控制的可靠性,缺點(diǎn)是增加了外部設(shè)備的數(shù)量,增加了費(fèi)用。增加一個(gè)環(huán)節(jié)也就意味著增加了故障發(fā)生的可能。信陽一期、益陽一期的DCS是由Bailey公司提供的INFI-90系統(tǒng),針對其系統(tǒng)結(jié)構(gòu)采用了公用環(huán),公用系統(tǒng)的控制全部通過公用環(huán)配置來實(shí)現(xiàn)。
