KUC755AE106自動(dòng)化模塊IGCT,KUC755AE106參數(shù)說明
SIS和DCS通過OPC進(jìn)行通信，可以有效避免不同軟件在同一系統(tǒng)中運(yùn)行的沖突，使SIS系統(tǒng)可以順利地利用DCS提供的必要數(shù)據(jù)從而實(shí)現(xiàn)功能。KUC755AE106但這種集成方式對(duì)于硬件的要求比較高，服務(wù)器配置高，大都需要進(jìn)口，價(jià)格也比較高，對(duì)于化工領(lǐng)域內(nèi)的中小企業(yè)會(huì)產(chǎn)生一定的經(jīng)濟(jì)負(fù)擔(dān)。
SIS與DCS的無縫集成
隨著計(jì)算機(jī)技術(shù)的發(fā)展，出現(xiàn)了一種集成SIS系統(tǒng)與DCS系統(tǒng)功能的電路板，這樣就避免了硬件不匹配的問題，通信無障礙。該集成方式將兩者在物理上的機(jī)型進(jìn)行集成，但在邏輯上相互分開，使得控制程序以及安全程序是相互獨(dú)立的，互不影響，同時(shí)執(zhí)行。
SIS與DCS無縫集成示意圖
這種特殊的集成方式使用相同的控制網(wǎng)絡(luò)線路和組態(tài)工具，數(shù)據(jù)的通信過程非常方便，不需要添加額外的接口和驅(qū)動(dòng)裝置。由于應(yīng)用了相同的監(jiān)測(cè)設(shè)備以及操作平臺(tái)，所以在具體的操作和通信過程中會(huì)更加便利迅捷。SIS系統(tǒng)和DCS系統(tǒng)可以同時(shí)使用控制系統(tǒng)的具體位號(hào)的信息，二者共享現(xiàn)場(chǎng)測(cè)量信息，無需添加新的組態(tài)。無縫集成方法節(jié)省人力，節(jié)約成本，通信安全迅捷，優(yōu)勢(shì)明顯。KUC755AE106自動(dòng)化模塊IGCT,KUC755AE106參數(shù)說明
液氨產(chǎn)品存儲(chǔ)通常用球灌裝，但球罐體控制系統(tǒng)十分復(fù)雜，控制出現(xiàn)不當(dāng)極易出現(xiàn)災(zāi)難性事故。球罐體壓力是一項(xiàng)重要的控制參數(shù)，當(dāng)球罐體壓力超過了設(shè)定值時(shí)，DCS系統(tǒng)通過現(xiàn)場(chǎng)測(cè)量裝置將實(shí)時(shí)測(cè)量數(shù)值回傳至SIS系統(tǒng)。SIS系統(tǒng)則根據(jù)事先程序設(shè)定值將自動(dòng)啟動(dòng)聯(lián)鎖裝置，切斷液氨繼續(xù)進(jìn)入罐體，使罐體不會(huì)因?yàn)橐喊背萘孔⑷攵l(fā)的危險(xiǎn)事故。

Using PAC control technology can effectively reduce production costs, improve production efficiency and achieve revenue growth for customers. Arc pointed out that although the price of PLC is gradually declining, its overall sales will still tend to rise in the next few years. As PAC, which combines the advantages of PC and PLC, we have reason to believe that with the continuous improvement, development and price of PAC technology gradually approaching PLC, PAC technology will become the mainstream of control system in the field of industrial automation in the future. Energy shortage and environmental pollution are an important problem facing today's society, and will become more and more serious. Although the massive construction of data center (IDC) has improved the level of global informatization, with the rapid growth of the number of servers and other IT equipment, it has led to a sharp increase in energy
