技術(shù)廣泛于鋼鐵的產(chǎn)品設(shè)計、生產(chǎn)、控制、設(shè)備與產(chǎn)品質(zhì)量診斷等各個方面,如高爐控制系統(tǒng)、電爐和連鑄車間、軋鋼系統(tǒng)、煉鋼———連鑄———軋鋼綜合調(diào)度系統(tǒng)、冷連軋等。分布式控制系統(tǒng)可以是兩級的、三級的或更多級的。隨著測控技術(shù)的,分布式控制系統(tǒng)的功能越來越多。DCS具有特點控制功能多樣化、操作簡便、系統(tǒng)可以擴展、維護方便、可靠性高等特點。分布式控制系統(tǒng)與集中型控制系統(tǒng)相比,其功能更強,具有更高的安全性。 Open Control System (OCS) Open Control System (Open Control System) is the development of puter technology led by the new structure concept. Open means a standard for the exchange of information in order consensus and support this standard design systems, different manufacturers products can be patible and interoperable, and the sharing of resources. Industrial control systems through open munication network so that all control equipment, management, puter interconnections, to achieve control and management, administration, integrated decisionmaking, through field bus to the scene and control room instrumentation control equipment interconnected to achieve integrated measurement and control of. 開放式控制系統(tǒng)(OCS)開放控制系統(tǒng)(Open Control System)是計算機技術(shù)發(fā)展所引出的新的結(jié)構(gòu)體系概念。開放控制系統(tǒng)通過工業(yè)通信網(wǎng)絡(luò)使各種控制設(shè)備、管理計算機互聯(lián),實現(xiàn)控制與經(jīng)營、管理、決策的集成,通過現(xiàn)場總線使現(xiàn)場儀表與控制室的控制設(shè)備互聯(lián),實現(xiàn)測量與控制一體化。目前鋼鐵企業(yè)已基本實現(xiàn)了過程自動化,但這種“自動化孤島”式的單機自動化缺乏信息資源的共享和生產(chǎn)過程的統(tǒng)一管理,難以適應(yīng)鋼鐵生產(chǎn)的要求。為了提高生產(chǎn)率、節(jié)能降耗、減少人員及現(xiàn)有庫存,加速資金周轉(zhuǎn),實現(xiàn)生產(chǎn)、經(jīng)營、管理整體優(yōu)化,關(guān)鍵就是加強管理,獲取必須的效益,提高了企業(yè)的競爭力。 Field bus Technology (FBT) Field bus Technology (Field Bus Technology) is the connection settings in the field of instrumentation installed in the control room and control devices for digital, bidirectional, multistation munication link. Field bus technology used to replace the existing signal transmission technology (such as 4 to 20 mA, DC DC transmission), it will enable more information in the field of Intelligent Instrumentation devices and higherlevel control system in the joint between the munications media on the twoway transmission. Field bus connection can be through save 66% or more onsite signal connecting wires. Field bus lead to the introduction of the reform and the new generation of DCS around open field bus automation system of instruments, such as intelligent transmitter, intelligent, field bus detection instruments, field bus of PLC (Programmable Logic Controller) local control stations and field development. 現(xiàn)場總線技術(shù)(FBT)現(xiàn)場總線技術(shù)(Field Bus Technology)是連接設(shè)置在現(xiàn)場的儀表與設(shè)置在控制室內(nèi)的控制設(shè)備之間的數(shù)字式、雙向、多站通信鏈路。通過現(xiàn)場總線連接可省去66%或更多的現(xiàn)場信號連接導(dǎo)線。 AC drive technology Transmission technology in the iron and steel industry plays a crucial role. With power technology and the development of microelectronics technology, the development of AC variable speed very quickly. The AC drive to the advantages of electric drive technology in the near future from AC drive pletely replace DC transmission, the development of digital technology, plex vector control technologies to achieve practical, AC variable speed system speed and performance has reached more than DC converter level. Now whether small or largecapacity electrical motor capacity synchronous motor can be used to achieve reversible induction motor or smoothing governor. AC drive system in the production of steel rolling emerged as a wele users, applications continues to expand. 交流傳動技術(shù) 傳動技術(shù)在鋼鐵工業(yè)中起作至關(guān)重要的作用。由于交流傳動的優(yōu)越性,電氣傳動技術(shù)在不久的將來由交流傳動全面取代直流傳動,數(shù)字技術(shù)的發(fā)展,使復(fù)雜的矢量控制技術(shù)實用化得以實現(xiàn),交流調(diào)速系統(tǒng)的調(diào)速性能已達到和超過直流調(diào)速水平。交流傳動系統(tǒng)在軋鋼生產(chǎn)中一出現(xiàn)就受到用戶的歡迎,應(yīng)用不斷擴大
