改進(jìn)的通信狀態(tài)字在巴基斯坦卡拉奇項(xiàng)目中的應(yīng)用
發(fā)布時(shí)間:2021-03-06 19:57
講述了通信狀態(tài)字在DCS一二層通信中的重要性,考慮到福清3/4項(xiàng)目中通信狀態(tài)字的定義種類繁多,而且每種類型內(nèi)部的狀態(tài)耦合嚴(yán)重,對種類進(jìn)行了簡化,并且對每種類型內(nèi)部的狀態(tài)進(jìn)行分組以解除耦合情況,使用改進(jìn)的通信狀態(tài)字,可以簡化一二層的接口設(shè)計(jì),提高圖符的復(fù)用率,提高工作效率,而且改進(jìn)的通信狀態(tài)字在巴基斯坦卡拉奇核電項(xiàng)目(K2K3)中應(yīng)用良好。

DCS系統(tǒng)結(jié)構(gòu)圖
BLOCK VALVE是一種典型的POT類型,分為78種狀態(tài),包括:normal fully open in auto、normal fully open in manual、normal fully closed in auto、normal fully closed in manual、normal opening in auto、normal opening in manual、normal closing in auto、normal closing in manual、caution fully open in manual、caution fully closed in manual、caution fully open protection、caution fully closed protection、caution opening protection、caution closing protection、failure fully open in auto、failure fully open in manual、failure fully closed in auto、failure fully closed in manual、failure intermediateposition in auto、failure intermediate position in manual、failure fully open protection、failure fully closed protection、failure intermediate position protection、tag on fully open、tag inhibit fully open、tag on fully closed、tag inhibit fully closed、tag on intermediate position、tag inhibit intermediate position、failure fully open with tag on、local fully open、local fully closed、local intermediate position、signal error等。如圖2所示。從圖2中可以看出,每種狀態(tài)包括32位,但是起作用的只有其中4~5位,這就造成每種狀態(tài)之間耦合嚴(yán)重,并且狀態(tài)數(shù)量達(dá)到80種之多,使得通訊狀態(tài)字的設(shè)計(jì)相當(dāng)復(fù)雜。
