現(xiàn)場(chǎng)總線控制技術(shù)作為一門新興技術(shù)，
已廣泛、
成功地應(yīng)用在關(guān)系民生的多個(gè)行業(yè)。
20
世紀(jì)
80
年代，
廣泛用于火力發(fā)電廠過(guò)程控制的系統(tǒng)是分散控制系統(tǒng)
（
DCS
）
和可編程控制器
（
PLC
）
。
80
年代末至今，
DCS
以其*的技術(shù)、豐富的控制功能、友好的人機(jī)界面等優(yōu)勢(shì)，
逐步占領(lǐng)了火電廠機(jī)、爐、電主控領(lǐng)域，而
PLC
則由于其邏輯處理功能強(qiáng)、境適應(yīng)性好、環(huán)
系統(tǒng)獨(dú)立性強(qiáng)、
采購(gòu)成本較低等特點(diǎn)，
成為電廠輔助生產(chǎn)系統(tǒng)和機(jī)組輔助系統(tǒng)的*控制系
統(tǒng)。
 
80
年代末期開(kāi)始發(fā)展起來(lái)的現(xiàn)場(chǎng)總線技術(shù)和產(chǎn)品，以及由此組成的控制系統(tǒng)——現(xiàn)場(chǎng)
總線控制系統(tǒng)（
FCS
，
Field
Control
System
）
，引發(fā)了自動(dòng)控制領(lǐng)域的革命。開(kāi)放的、全數(shù)
字化和雙向多站的通訊網(wǎng)絡(luò)，
與多功能的智能化現(xiàn)場(chǎng)數(shù)字儀表是
FCS
的主要特征，
它將使自
動(dòng)控制系統(tǒng)的效能產(chǎn)生巨大的飛躍。
 
一、現(xiàn)場(chǎng)總線的定義及特點(diǎn)
 
根據(jù)電工委員會(huì)
IEC61158
標(biāo)準(zhǔn)的定義：安裝在制造或生產(chǎn)過(guò)程區(qū)域的現(xiàn)場(chǎng)裝置與
控制室內(nèi)的自動(dòng)控制裝置之間的數(shù)字式、串行、雙向、多點(diǎn)通信的數(shù)據(jù)總線稱為現(xiàn)場(chǎng)總線。
由現(xiàn)場(chǎng)總線與現(xiàn)場(chǎng)智能設(shè)備組成的控制系統(tǒng)稱為現(xiàn)場(chǎng)總線控制系統(tǒng)
FCS(Fieldbus Control
System)
。
FCS
的核心是總線協(xié)議，只有遵循現(xiàn)場(chǎng)總線協(xié)議的控制系統(tǒng)，才能稱為現(xiàn)場(chǎng)總線
控制系統(tǒng)；
FCS
的基礎(chǔ)是數(shù)字智能現(xiàn)場(chǎng)儀表，它是
FCS
的硬件支撐；
FCS
