描述
DCS(Distributed Control System)系統(tǒng)廣泛應(yīng)用于火電、石油化工、造紙、建材和冶金等工業(yè)生產(chǎn)制造環(huán)境中。該系統(tǒng)繼承了常規(guī)儀表分散控制和計(jì)算機(jī)集中控制的優(yōu)點(diǎn),克服了常規(guī)儀表功能單一、人機(jī)交互差和單臺(tái)計(jì)算機(jī)控制系統(tǒng)危險(xiǎn)性高度集中的缺點(diǎn),同時(shí),它實(shí)現(xiàn)了管理、操作和顯示三方面的集中,以及功能、負(fù)荷和危險(xiǎn)性三方面的分散。典型DCS硬件系統(tǒng)由工程師站、操作員站、服務(wù)器、控制器、I/O從站、控制網(wǎng)絡(luò)及設(shè)備、系統(tǒng)網(wǎng)絡(luò)及設(shè)備、電源、機(jī)柜和操作臺(tái)組成,如圖1所示。在I/O從站中有一種開關(guān)輸入信號(hào)(DI),普通項(xiàng)目對(duì)DI信號(hào)的分辨率要求不高,大約為200~300 ms。在實(shí)施某重大項(xiàng)目數(shù)字化數(shù)據(jù)采集和集中處理系統(tǒng)(KIT/KPS)改造時(shí),要求DI信號(hào)采集分辨率達(dá)到50 ms,并且能夠同時(shí)記錄現(xiàn)場(chǎng)開關(guān)動(dòng)作的時(shí)間。在DCS控制系統(tǒng)中,高分辨率和時(shí)間信息記錄是為了能夠依次分辨該高速DI信號(hào)之間的聯(lián)鎖關(guān)系(如汽輪機(jī)軸承油壓低聯(lián)鎖主汽閥門關(guān)閉),判斷各信號(hào)是否符合一定的動(dòng)作順序。目前DCS系統(tǒng)普通型DI模塊性能,無法滿足對(duì)這些信號(hào)的采集要求,因此需要對(duì)DCS系統(tǒng)DI信號(hào)處理方法進(jìn)行升級(jí)改進(jìn)。
