Production Information Management System Of The West Region Of Lanzhou Petrochemical Corp

In order to speed up the information construction and meet the requirement of urgent grasp on the process data of the chemicals production demanded by the manufacturing, management, and decision-making departments of Lanzhou Petrochemical Corp., and combined with the real situation of the process control in chemicals plant, hereafter comes up with a briefing on the modules' functionality in the production message management system. The structure of one system of management and control was decided, this system considers the real-time database as the data storage platform and relationship database as the core production database and data acquisition as foundation.A detailed analysis on the communication interfaces of hardware and software in different DCS system, for instance software interfaces OPC, NETDDE, FASTDDE, TPSDDE, hardware interfaces ACG10S, ECGW3, CGWU, and RS81, was made in the main manufacturing plant of lanzhou Petrochemical Corp.. A program of Client/Server structure using to solve the data acquisition between different communication interfaces was designed. The data from manufacturing process to the real-time database comes true. And also the functions of the data display in the flowsheet, the real-time data browsing, process alarm, and history etc.based on Browser/Server structure come true.According to the software application in the manufacturing, a material balance data, energy-calculated data, and production deploying data are abstracted and coordinated. The real-time manufacturing data can be written into the core database for these data through a special interface program on timing demand. Considering application of the data, the material balance system and energy-calculated system for petrochemical factory and chemical fertilizer factory were developed. The deploying system for the Lanzhou Petrochemical Corp. including sub-company was developed and perfected.An integrated inquiry system by using Browser/Server structure and Php,Jsp technic was formed. The main mindset of the program design at present such ascomputer network technology, communication technology, real-time database technology and relationship database technology were applied through the system design. A manufacturing message management system incorporated completely with production safety, communication safety and data safety gained a broadly application in chemicals production.
