Study On E-maintenance System Architecture And Key Technique Of Manufacturing Equipment

Plant maintenance is a central and critical aspect of control in business success,and is gaining recognition as a significant factor in sustainable development of the society。The improvement of plant maintenance can enhance business's competitive ability as a whole,and effectively the harmonious development of production,environment and society。In the context of economic globalization,manufacturers must not only produce high-quality,personalized products,but also to provide full life cycle product service and maintenance,with the network technology and communication technology development equipment maintenance decision-making technology continues to innovation,based on remote monitoring and fault diagnosis, the e-maintenance system came into being,e-maintenance system can provide timely on-line maintenance of the equipment to achieve near-zero fault condition。In order to improve the overall competitiveness of China's manufacturing industry,we must improve the business model of the traditional equipment maintenance,therefore,based on intelligent e-maintenance system characteristics and trends,this paper applies e-maintenance system to manufacturing enterprises,puts forward a new e-maintenance system architecture and studies the key technique。Paper first analyzes the importance of equipment maintenance of the modern enterprise,introduces the production and development of the e-maintenance theory, and then illustrates the background of the manufacturing e-maintenance system,on this basis,designs a new e-maintenance system framework and functions of manufacturing industry on the basis of the domestic and foreign e-maintenance system status。Secondly,this article applies CBR (Case-based Reasoning) fault diagnosis technology for the fault diagnosis system of e-maintenance to improve the fault diagnostic capabilities of equipment;followed the research of the model library,knowledge base and database;in the model library regard,it proposes model base system architecture and the function of the composition of modules,focusing on the model representation and selection of methods of analysis;in the knowledge base,the establishment of a knowledge-based systems architecture studies the key technologies to achieve the knowledge base,and focuses on knowledge acquisition methods ; in the database , it proposes the data warehouse architecture of manufacturing e-maintenance system,designs data warehouse model and implements the data warehouse technology;paper also analyzes the decision-making model,that is, decision-making model of maintain way and decision-making model of maintain cycle which laies the foundation for development of the maintenance。Finally,the paper summaries the contents of this research,and analyzes the contents of the next study in order to lay a foundation for further study。...
