Application Technology Research On The Information Integration System Of Equipment Maintenance And Process Supervisory And Control

It is an. essential characteristic that the future manufacturing market should be uncertainty, which appears dynamic change and unexpectedness. The internationalization and globalization have become another key characters of the future market. Due to the above changes, the manufacturing enterprises who want to win the dominance of the competition, is forced to make great evolutions both in the organization structure and production mode, as well as adopting the advanced manufacturing technologies. Advanced manufacturing mode such as Agile Manufacturing and Distributed Network Manufacturing has been developed and widely used. Suit to above manufacturing architecture, manufacturing enterprises need to build supervisory and control system for enhancing supervising and controlling to the manufacturing system and business process, which faced to the whole manufacturing process. Therefore, this is the basic need of both Manufacturing System (MS) and the information platform of the advanced manufacturing architecture in manufacturing industry.Currently, the research on the monitor and control systems is focused on the equipment conditions degradation, and ignore the monitor of manufacturing process. It's my belief that two aspects of process monitor and control should be concerned at least: one is the control of process performance which is based on time; the other, elements in the process (person, information, technology, environment and so on) and the changes of the relationships. From this point of view, the supervisory and control to the manufacturing process should also involve the two aspects mentioned above. One is to monitor and control the equipments condition in the MS, the other is to supervise and control the process.According to the progress of Networked manufacturing, a Network-based Reconfigurable Manufacturing system (NRMS) is needed. There are some difference between the NRMS and the traditional MS such as the manufacturing resource ownership and the process distribution which led to the idea evolution of equipment maintenance.In this paper, we discuss the relationship between maintenance system and enterprise integration, and conclude the following , with the progress of the enterprise integration, a kind of the network-based, moreintelligence integrated system of MS and the maintenance systems would be needed. According to the needs of maintenance exoterica and the enterprise integration, we put forward an intellectual equipment maintenance system (IEMS) framework, through which implement the integration of equipment maintenance system and the other information systems used in manufacturing enterprise. We research on the need of different manufacturing units, normal systems and the emergency systems, then provide some different solutions. As the result, the integration methodology of IEMS is expanded to NRMS Equipment Maintenance System (NREMS).In a NRMS, all the processes are fulfilled in distributed units, the whole manufacturing system will be break down while malfunctions happen, so it is very important to set up a Manufacturing Process Supervisory and Control System (MPSCS) to control the whole manufacturing process. In this paper, firstly, we discuss needs of the integration of the equipment maintenance system and the network manufacturing system, then analysis the integration of the two systems. Secondly, we research the integration technology and set up an information integration system of equipment maintenance system and MPSCS. Thirdly, we mainly research on the data collection, central manipulate and distribute technologies of the information integration system. It is also our contribution to introduce message mechanism into the system to improve the coordinative performance in distributed systems. Finally, we develop a software to illustrator the visual MPSCS in the network manufacturing architecture, which relied on our supporting project- Manufacturing Resource Optimize Based Manufacturing Process Management System which is sponsored by the national 863 plan,(project No.
