Construction And Application Of FMS Digital Twin System Driven By Real-time Data

In recent years,with the development of information technology,a new round of industrial transformation and technological revolution has emerged,which has made intelligent manufacturing an inevitable trend in the development of the manufacturing industry.In the practice of intelligent manufacturing,digital twin is widely concerned and studied as the best solution to achieve the integration and interaction between physical space and information space.However,the digital twin technology is still in the theoretical research stage,and the research on the application of digital twin is also in the exploratory and practical stage,The application of digital twin technology to the field of mechanical manufacturing is a current research hotspot.Driven by intelligent manufacturing,the market’s demand for FMS continues to increase,and more and more manufacturing enterprises begin to use flexible manufacturing line to engage in manufacturing activities,which leads to higher requirements for manufacturers of flexible manufacturing line:In order to improve competitiveness,FMS needs to be more intelligent;in the case of increasing orders,it still has to deliver on time.Therefore,a machine tool factory that produces flexible manufacturing production lines puts forward a demand for MES.The subject research aims at improving the economic benefits of the enterprise,starting from improving the debugging efficiency of the control program of the dispatching execution system,and starting from the virtual debugging of the control program.The FMS digital twin system was constructed using digital twin technology,and this system was applied to the virtual commissioning and on-site debugging of the control program of the dispatching execution system.The construction method and technology of the digital twin system based on real-time data driven was focused on the system.The design and implementation are combined with actual application cases to verify the effectiveness of the constructed system and the feasibility of the construction method.Firstly,according to the research projects for the subject,the current situation of the flexible manufacturing production line FMS80 produced by a machine tool factory and the construction requirements of digital twin system are analyzed.Based on the related theories and technologies of digital twin,a digital twin system architecture for flexible manufacturing production line applications is proposed.Then,according to the construction requirements of the digital twin model and the analysis of common commercial industrial simulation software,Visual Components(VC)software is selected as the construction environment of the digital twin system.Secondly,the construction method and process of the digital twin model of FMS key equipment are researched,and its construction is realized.At the same time,At the same time,an interface for signal behavior is established in the digital twin model according to requirements,which provides support for subsequent real-time data acquisition and real-time mapping research work;Using ADS communication technology to construct a communication network for real-time data of the FMS digital twin system,realizing the acquisition of real-time data of physical entities by the digital twin model,providing the data and communication support for subsequent virtual-real synchronization;A real-time data-driven logical architecture are proposed,the purpose of using the obtained real-time data of physical entities to drive the digital twin model for real-time mapping is realized by writing Python scripts.Finally,the realization process of the FMS digital twin system is summarized,and this system is applied to the virtual commissioning and on-site commissioning of the control system program of the flexible manufacturing production line FMS80 produced by a machine tool factory,which verified the validity of the digital twin system constructed.This system can help programmers to find problems in the control program before they go to the site quickly and conveniently,after they go to the site,the programmers can also use the virtual and real synchronization function realized by this system to solve the problem that programmers are not convenient to examine the status of the device that was debugged.In general,it improves the efficiency of commissioning,shortens the commissioning cycle,speeds up the delivery of the project,and improves the economic benefits of the enterprise in the long run.
