【正文】 process monitoring, operation, management and decentralized control. 6 With monitoring and control technologies, and the functions of distributed control system more and more. Not only can be achieved control of the production process, but also can be achieved online optimization, the production process realtime scheduling, production planning statistical management functions, as a measurement, control, integration of the integrated system. DCS control functions with diverse features and easy operation, the system can be extended, easy maintenance and high reliability characteristics. DCS is decentralized and centralized control monitoring, faultminor, and the system has the chain protection features, the use of manual control system failure operational measures, the system is highly reliable. Distributed control system and centralized control system pared to their more functional, with a higher level of security. Is the largescale integration of mechanical and electrical systems main trend. 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 work so that all control equipment, management, puter interconnections, to achieve control and management, administration, integrated decisionmaking, through fieldbus to the scene and control room instrumentation control equipment interconnected to ac hieve integrated measurement and control of. Computer Integrated Manufacturing System (CIMS) CIMS is the iron and steel enterprises will be and the production and operation, production management and process control connecting to achieve from raw materials into the plant, production and processing of shipments to the entire production process and the overall integration process control. Currently iron and steel enterprises have basically achieved process automation, but this kind of automated island of single automation lack of information resources and the sharing of the unified management 7 of the production process, can hardly meet the requirements of the iron and steel production. Future petition iron and steel enterprises is the focus of many varieties, small batch production, cheap and of good quality, timely delivery of goods. In order to improve productivity, saving energy, reducing staff and the existing inventory, accelerate cash flow, production, operation and management of the overall optimization, the key is to strengthen the management, access to the benefits of raising the petitiveness of businesses. The United States, Japan and some other largescale iron and steel enterprises in the 1980s has been widely realization of CIMS. Fieldbus Technology (FBT) Fieldbus Technology (Fied 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. Fieldbus technology used to replace the existing signal transmission technology (such as 4 to 20 mA, DC DC transmission), it will enable more info
