| In recent years, with the high-speed development of the manufacturing industry and the increased competition of manufacturing market, the traditional management methods could not satisfy the production takt. The monitoring and management for production process of most enterprises in China is still staying in manual records stage, which will produce the postponement of demanding information, low visibility and produce efficiency, and hidden danger for production workshop. The assembly process of mechanical products is the typical discrete manufacturing process. Moreover, the production technology for the assembly process of mechanical products is complex, and it is hard to collect the large amounts of information for the assembly process of mechanical products. Therefore, there is absolutely a need of management methods for the enterprises to monitor the production workshop, which could guarantee the production operations. According to above problems, this paper studies the visual monitoring technology for the assembly shop of mechanical products, and designs a real-time monitoring of production workshop visualization platform (RM-VP), which has advantages including real-time, high-efficient, excellent interaction and scalability. The contents are as followed:Firstly, this paper analyzes the features and information classification of the assembly shop of mechanical products, and studies information integration technology which is the key technology of visual monitoring technology for the production workshop. Based on RFID and OPC, this paper researches the detailed workflows of information perception, information value-added and information classification for the assembly shop of mechanical products. Then, object-oriented method and graphic technology(GDI+) are used to design a visual object model (VOM). Meanwhile, the object data model, visual presentation model and user interaction model of VOM are defined. On this basis, the RM-VP is designed and the system frame and database model of RM-VP is constructed. Moreover, this paper studies how to build a production workshop model by RM-VP and explores the operation mechanism of RM-VP. Finally, taking an automatic transmission enterprise as a case study to verify the proposed platform is stable and reliable. |
