FCS系統(tǒng)的基礎(chǔ)是數(shù)字智能現(xiàn)場(chǎng)裝置
數(shù)字智能現(xiàn)場(chǎng)裝置是FCS系統(tǒng)的硬件支撐,是基礎(chǔ),道理很簡單,F(xiàn)CS系統(tǒng)執(zhí)行的是自動(dòng)控制裝置與現(xiàn)場(chǎng)裝置之間的雙向數(shù)字通信現(xiàn)場(chǎng)總線信號(hào)制。如果現(xiàn)場(chǎng)裝置不遵循統(tǒng)一的總線協(xié)議,即相關(guān)的通訊規(guī)約,不具備數(shù)字通信功能,那么所謂雙向數(shù)字通信只是一句空話,也不能稱之為現(xiàn)場(chǎng)總線控制系統(tǒng)。再一點(diǎn),現(xiàn)場(chǎng)總線的一大特點(diǎn)就是要增加現(xiàn)場(chǎng)一級(jí)控制功能。如果現(xiàn)場(chǎng)裝置不是多功能智能化的產(chǎn)品,那么現(xiàn)場(chǎng)總線控制系統(tǒng)的特點(diǎn)也就不存在了,所謂簡化系統(tǒng)、方便設(shè)計(jì)、利于維護(hù)等優(yōu)越性也是虛的。
(3) FCS系統(tǒng)的本質(zhì)是信息處理現(xiàn)場(chǎng)化
對(duì)于一個(gè)控制系統(tǒng),無論是采用DCS還是采用現(xiàn)場(chǎng)總線,系統(tǒng)需要處理的信息量至少是一樣多的。實(shí)際上,采用現(xiàn)場(chǎng)總線后,可以從現(xiàn)場(chǎng)得到更多的信息。現(xiàn)場(chǎng)總線系統(tǒng)的信息量沒有減少,甚至增加了,而傳輸信息的線纜卻大大減少了。這就要求一方面要大大提高線纜傳輸信息的能力,另一方面要讓大量信息在現(xiàn)場(chǎng)就地完成處理,減少現(xiàn)場(chǎng)與控制機(jī)房之間的信息往返??梢哉f現(xiàn)場(chǎng)總線的本質(zhì)就是信息處理的現(xiàn)場(chǎng)化。
減少信息往返是網(wǎng)絡(luò)設(shè)計(jì)和系統(tǒng)組態(tài)的一條重要原則。減少信息往返常??蓭砀纳葡到y(tǒng)響應(yīng)時(shí)間的好處。因此,網(wǎng)絡(luò)設(shè)計(jì)時(shí)應(yīng)優(yōu)先將相互間信息交換量大的節(jié)點(diǎn),放在同一條支路里。
減少信息往返與減少系統(tǒng)的線纜有時(shí)會(huì)相互矛盾。這時(shí)仍應(yīng)以節(jié)省投資為原則來做選擇。如果所選擇系統(tǒng)的響應(yīng)時(shí)間允許的話,應(yīng)選節(jié)省線纜的方案。如所選系統(tǒng)的響應(yīng)時(shí)間比較緊張,稍微減少一點(diǎn)信息的傳輸就夠用了,那就應(yīng)選減少信息傳輸?shù)姆桨浮?br />
現(xiàn)在一些帶現(xiàn)場(chǎng)總線的現(xiàn)場(chǎng)儀表本身裝了許多功能塊,雖然不同產(chǎn)品同種功能塊在性能上會(huì)稍有差別,但一個(gè)網(wǎng)絡(luò)支路上有許多功能雷同功能塊的情況是客觀存在的。選用哪一個(gè)現(xiàn)場(chǎng)儀表上的功能塊,是系統(tǒng)組態(tài)要解決的問題。
考慮這個(gè)問題的原則是:盡量減少總線上的信息往返。一般可以選擇與該功能有關(guān)的信息輸出最多的那臺(tái)儀表上的功能塊。
