.125 The Mn Extrusion Machine Research And Development Of The Host Computer System

As an efficient testing,controlling and dispatching method in manufacturing facilities and the process of production,Monitoring System is widely used in industry with the development of information technology.Chinese technical level falls behind the developed countries in extruding machines,alteration mode is applying mechanical, electrical and hydraulic technology base on old machines in common and realize the new function in old instruments.The 125MN extruding machine is the largest extruding machine in China and is the key instrument in national defence and basic build. The current controlling modes in extruding machine is evident lag, the component ages , the low precision of control, the bad dependability, and lack every detection which operate the actuating mechanism and control the course record.We carry on modernized transformation to it now, set up good man-machine interface, has improved working efficiency and precision of the extruding machine greatly. The thesis main part works as follows:1. Combining the technologic characteristic and alteration requirement of 125MN extruding machine, the article constructed the second level PLC distributing model control system which include epigynous machine of WinCC, touching screen, main and frae station, and detailedly introduced the roboticized systemic hardware configuration, network configuration and control function, achieving the collected administration and separated control about the extruding machine.2. Contraposing rigorous demand that the part data traffic speed of 125MN extruding machine must reach 10ms, we adopted the special data traffic to reach the high speed purpose, and breached the most pigeonhole frequency of WinCC 500ms.3. Using the interior compositive the relation data-base SQL Server 2000 and customer pigeonhole (user archive), we constituted real time data-base system. And using esting connection between the high class language and the SQL Server 2000, we achieved the flexible data querying and manufacture managerial function.4. Basing on modularization design idea, we empoldered the epigynous machine watching system which is the combination of the WinCC configuration software and the touching screen. This system achieved many functions, including data collection, fettle watching, intelligence control and produce management and so on, and offered favorable man-machine interface.
