| The automation reform and info integration for paper pulp mixed control system is one of the sub-projects of Jiangsu Jinlian Paper Co., Ltd. information project, an information pilot project chosen by the Economic & Trade Commission of Jiangsu Province. It is an important part of the information of producing system.Paper pulp mixed system is an important part of the whole flow of page making. By way of reaching the request of mixing system, ensuring quality and output, we must alter this system automatic, at the same time ,by way of using all kinds of production data of this system adequately , making this system accept the guidance of information system of the whole factory and avoiding to be quot, we must link this system to the MIS of the whole factory. I researches some technique problem of the automatic control of paper pulp mixing system and info integration. This system hardware construction adopts an Industry control solution based Industry control computer, which carry out control logic on IPC, IPC handle input and output by I/O plank card.This system software construction is a three layer Construction which includes operation and manifestation procedure, control procedure based DDCRun and interface procedure based DLL. Interface procedure offers the interface of hardware; Control procedure realizes the automatic control of paper pulp mixing system; Operation and manifestation procedure includes function module and info integration module. Function module includes real time scout and controlling, curve displaying, statistical and report forms and parameter setting etc. Info integration module includes the design of real time database, the design of relation database and the interface of them.This system have virtues thereinafter, powerful function, friendly interface, easy debug, convenient configuration and steady run etc.Up to now, this system has produced great economic and social benefits. The investment is returned in less than a year.
