The Research Of Multi-source Information Intelligent Collection And Monitoring Method For NC Machining Process Based On Multi-Agent

Currently,intelligent manufacturing has become one of the most important development trends of traditional manufacturing enterprises.However,the manufacturing enterprises are faced with the problems as intelligent acquisition,real-time interaction and visual dynamic monitoring of machining processing information in shop floor,which affect the process of intelligent building for enterprises.Based on the domestic and foreign research results,this paper explores and studies the unified description and modeling of NC machine tool machining information,the collection and integration of machining information,as well as the visual dynamic monitoring technology in the intelligent manufacturing environment.First of all,an implementation framework is proposed by analyzing the classification and characteristics of multi-source information of NC machining process,which includes the unified description and modeling of CNC machines,the intelligent acquisition and integration of multi-source information,as well as the visualization of dynamic monitoring technology in intelligent manufacturing environment.Secondly,based on the proposed framework,the key technologies are studied in detail,including a description and modeling method of CNC machine tools based on the MTConnect unified information model;an acquisition and integration method for CNC machine intelligent information based on Multi-Agent,which can implement the information intelligent collection and integration of specified CNC machining process with different interface;a Multi-Agent based visual dynamic monitoring technology to realize the hierarchical,diversification,personalization and visual monitoring of CNC machining process information.Finally,an intelligent information acquisition and monitoring system for CNC machining process is designed and developed in this paper.The above analyses are illustrated in some specific realistic CNC machine tools and the result shows a great efficiency and practical feasibility and that it’s an effective approach which has a better performance in practical application.
