| Electroplating industry, which is widely used in household products and defense industry of different areas,occupies an important position in the manufacturing industry. Currently, electroplating industry of China represents a phenomenon of low automation level. Most electroplating product lines are workshop-style manual and semi-automatic. And existing automatic lines are limited to single variety and fixed electroplating process. Also management in electroplating workshop is lacking of advanced management system to standardize the management of electroplating.Considering the particularity of electroplating production, this paper researches and developes a set of management system for automatic felixible electroplating product lines based on the project"Design and Mamufacture of automatic electroplating lines". The system is designed to manage flexible automatic electroplating workshops, which can process multi electroplate types. Besides, it should maintance, monitor and record every avaible. Firstly, framework and function of the system are presented based on MES and electroplate process. UML is applied to analysis demands, structure and process activity. Secondly, XML is employed to discribe electroplate craft and database is designed. Thirdly, single hoist schedule and multi-hoist schedule are researched to satify process routes constraints, tanks capacity constraints and hoists capacity constraints. Then, based on OPC technology, communication layout is designed to realize data exchange.Based on C/S pattern and object-oriented designing method, SQL Server2005 database and Visual C# 2005 are selected to accomplish this system.The running results show that the system totally satifies the design requirement. It makes electroplate process controllable and recur process result. The research can not only rise the automation level of electroplating industry, but also provide some reference significance for other automation practice. |
