IC693DNM200

數(shù)字通訊是一種趨勢(shì)，它代表了技術(shù)進(jìn)步，是任何人阻擋不了的。雙向數(shù)字通信現(xiàn)場(chǎng)總線信號(hào)制以及由它而產(chǎn)生的巨大的推動(dòng)力，加速現(xiàn)場(chǎng)裝置與控制儀表的變革，開(kāi)發(fā)出越來(lái)越多的功能完善的數(shù)字智能現(xiàn)場(chǎng)裝置。這些都是DCS系統(tǒng)所不具備的，而由此產(chǎn)生的優(yōu)越性以及給火電廠的設(shè)計(jì)、配置、組態(tài)、運(yùn)行、維護(hù)、管理等方面帶來(lái)的效益也是DCS系統(tǒng)所不及的。再則，F(xiàn)CS是由DCS以及PLC發(fā)展而來(lái)，它保留了DCS的特點(diǎn)，或者說(shuō)FCS吸收了DCS多年開(kāi)發(fā)研究以及現(xiàn)場(chǎng)實(shí)踐的經(jīng)驗(yàn)，當(dāng)然也包括教訓(xùn)。由此而得出結(jié)論，“FCS將取代DCS”，似乎也是順理成章之事。

DCS系統(tǒng)的關(guān)鍵是通信。也可以說(shuō)數(shù)據(jù)公路是分散控制系統(tǒng)DCS的脊柱。由于它的任務(wù)是為系統(tǒng)所有部件之間提供通信網(wǎng)絡(luò)，因此，數(shù)據(jù)公路自身的設(shè)計(jì)就決定了總體的靈活性和安全性。數(shù)據(jù)公路的媒體可以是：一對(duì)絞線、同軸電纜或光纖電纜。
通過(guò)數(shù)據(jù)公路的設(shè)計(jì)參數(shù)，基本上可以了解一個(gè)特定DCS系統(tǒng)的相對(duì)優(yōu)點(diǎn)與弱點(diǎn)。
