Design of the equipment information acquisition system for re-configurable and flexible shop floor

The manufacturing processes in a product are different according to the characteristics of the product and the information within the process is also varied. To implement the flexible MES, the Data Acquisition System (DAS) considering the characteristics of manufacturing system is needed. In this paper, we introduced the design of the equipment information acquisition system that can process the information of shop floor in real-time and adaptive to the changes of shop floor. The proposed system is the bridge between the shop floor and the Manufacturing Execution System (MES). It provides the MES the shop floor information between the work order and the results of work performance. The proposed system provides a data parser module to process equipment status in a flexible manner and a data mapper module to couple the equipment status to a manufacturing process and a SOA-based data integration module to link the processed shop floor information to upper system such as MES and ERP. The system is highly configurable system and easy to maintain even if new equipment or manufacturing process is inserted or re-arranged.
