The Study And Actualize On MES Of Chongqing Iron & Steel Company Limited The Cold Rolled Strip Mill

MES the frame got up a bridge in the plan management level and between the first floor control, has filled two between crevice. It on the one hand may to come from ERP/The MRPII software production management information is thin, the decomposition, the operational order will transmit to the first floor control; On the other hand, MES may the real-time monitoring first floor equipment running status, gather the measuring appliance, the equipment condition data, the process analysis, the computation and processing, triggers the new event, thus convenient, will be reliable the control system and the information system relates in together.This article has analyzed the domestic and foreign MES research present situation, has forecast the MES development tendency, summarized the domestic metallurgy profession MES implementation experience and the lesson. Through to the MES system structure research and the discussion, has made the improvement design with the bar code technology to the MES production job control and the storage management, finally, take the metallurgy profession MES system as the example, has carried on the discussion to the MES system optimization steel and iron manufacture flow.The paper main work is: Through research which carries on to the manufacturing industry becoming an information based society model, (how thoroughly analyzed a MES system objective to make carries out), two cores databases (real-time database and relational database), two correspondences connections (and control level connection and with service plan level connection), four key functions (production management, craft management, process management and quality control) and seven auxiliary functions. Unifies the Chongqing steel and iron limited liability company cold rolling sheet-metal mill the actual demand, designed a set to suit the metallurgy profession the MES system. The result indicated that, utilizes the advanced bar code technology in the steel and iron production line, reduced in the production process mistake rate, enhanced the production efficiency and the product quality, has saved the human resources and the office expense, reduced the stock fund backlog, the effect is ideal.This article used the software engineering the life cycle law to carry on the system analysis and the design to the Chongqing steel and iron limited liability company cold rolling sheet-metal mill manufacture execution system. This design network operating system uses Red Flag Linux 4.1, The database management system uses Oracle9i RAC, the development kit uses Oracle development kit Forms6i and Reports6i, the connection...
