Research And Application Of Virtual Integration Theory In The Integration Of Management And Control Of Process Industry

With the considerable improvement in the process of integration of managementand control, enterprise informatization demands an increasingly high requirement.Meanwhile, difficulties in carrying out informatization of integration of managementand control are caused as a result of the imbalance of enterprise informatizationconstruction and diversity and heterogeneity of informatizatin system. How to solvethis problem with the integrated application of management technology, automationtechnology, and information technology has currently become a hot topic of enterprisemanagement research.After analyzing and studying integration of management and control and itsdevelopment, and on the basis of learning the status quo of this field inside andoutside and making detailed researches on related technology on this project, thisarticle, aiming at the current situation and requirements of process industryinformatization construction, brings forward theory of virtual integratioin. With theapplication of comprehensive technology, virtual integration aims at taking fulladvantage of enterprises'existing informatization achievement, and acomplishing theintegration of process virtualization and data, so as to acquire information sharing anddata fusion. Based on the system structure of process industry management andcontrol integration, this article discusses the technique framework of virtualintegration, including data integration technology, virtual DCS technology, datainterface technology, and real-time database and information presentation technology.Combined with water saving and sewage reduction informatization constructionproject of Sinopec, the idea of virtual integration has been applied to the virtualintegration development of industrial cycling water successfully. With theimplementation of quick search and analysis of circulating water process equipmentand its process data, process operating distribution and the operating condition ofequipment is clear to all users. The information management system of water savingand sewage reduction becomes more scientific and standard. On the basis of theheterogeneity of cycling water DCS system, OPC interface technology is adopted todevelop and complete data communication and exchange in the production process,and achieve data integration of heterogeneous control network in field control. As thenew standard of Industrial Control in the world, OPC technology has overcome the difficulties in data exchange among companies and standardized application interfacedesign, and achieved great improvement. The application of OPC technologyguarantees reliability, standardization, and certain technical advancement of systemcommunication, and lay the foundation for system expansion. With the application ofWEB technique, progress process data, LIMS data, and MES data etc. are integratedand displayed, and the expected development objective is accomplished.In general, the idea of virtual integration can effectively solve the problems facedin the course of process industry management and control integration, such asinformatization development imbalance, control network diversity, and the irregularityof technology level and so on. It is a kind of technical thought of high feasibility andcost performance, and it has high engineering value and extension.
