Pulp And Paper Computer Integrated Process System Research And Implementation,

Flow industry is an enterprise of continuous and semi- continuous process of manufacture. Computer integration process system (CIPS) for flow industry is a complicated system of integrate automation. The key problem of CIPS project feature is process supervision and information integration. The framework oriented system function consists of four independent systems: prosecution management, process automation, safe economic running, computer network and database. This paper mainly discusses integration and application of two supportive environments: computer network and database.Yun-Jing corporation adopts continuous way of chemistry to produce bleach pulp & paper plank of timber fibrin, it is a typical flow enterprise. Information islands about the management of operation and the automation are common phenomena existing in flow enterprise. The unstandardized managements of operation and the complexity of chemical flow manufacture control system decide that realizing integration and application of enterprise information should adopt integrated automation system , so that it can resolve these phenomena, enhance the whole benefit and competition. The characteristic and the fact of producing flow in the pulp & paper and the content of CIPS decide it is feasible that CIPS could be applied in this area.The integration of network information system exerts advanced computer and communication technology to integrate small running environment of each information island into a great one. It includes the integration of technology environment, data environment and applied program. The integration of network is the base of technology and the running desk. Its contents include structure, transmission, switcher, server, operating system and so on of ethernet. The integration of data exerts some technologies to organize different data into a whole according to rules in order that the user can operate these data effectively. The main processing objects are data of different data sources in system. Theindustrial control software integrates seamlessly real-time database and many interfaces of communication with the third party programs. These traits become it into an excellent platform of data integration.The general industrial control software includes graphic interface system, the third party program module, control function module and real-time database system module etc. Its main feature is real-time multitask, and the real-time database is its kernel and engine. SQL in industrial control software realizes accessing function and data transmission with other ODBC database. As a uniform accessing interface of database, ADO will become an accessing standard of database for windows in future. By these ways, the industrial control software may be data provider, as well as data user, consequently realize bidirectional communication and general application between industrial field data and other MIS.The production scheduling and managing system of pulp 6 paper on the basis of the mentioned technology platform realizes seven main functional modules including real supervising module, and satisfies the demand of production after running. The system adopts the technology such as script language, OPC etc to perfect and improve the functional expansibility, openness, security of system.
