Research On Key Technologies Of Model-driven Tool Chain Development For Cyber-physical Production Line

Intelligent manufacturing is the inevitable way to guide the upgrading of the manufacturing industry and realize the transformation of production mode.However,the information interaction between the hybrid and heterogeneous development tools of the intelligent manufacturing system brings great challenges to the system development.In this context,model-driven development technology is used to model the information of development tools,which can effectively reduce the complexity of the system and improve the development efficiency.It is of great significance of the theoretical research and technical implementation of intelligent manufacturing.This paper takes the model-driven tool chain development for cyber-physical production line as the research goal.The main work completed are as follows:Firstly,the information integration architecture of cyber-physical production line is proposed.The advantages and characteristics of Automation ML,domain-specific modeling language,model transformation and generic modeling environment are analyzed,which lay a foundation for the model-driven tool chain development for cyber-physical production line.Secondly,based on the information integration architecture,the model-driven development method of cyber-physical production line is proposed.The metamodel and domain model are constructed based on the proposed concept of production line modeling.The mapping rules of domain model to ontology model,formal model and logical behaviour model are defined as the basis for semantic reasoning,planning and scheduling,function and performance verification and virtual commissioning of production line.The mapping rules of domain model to OPC UA information model are defined.Open62541,an open source implementation of OPC UA,is used for code generation.It serves as the basis of the deployment of information communication framework for different manufacturing units in cyber-physical production line.Thirdly,the tool integration method of cyber-physical production line is proposed,and the generic modeling environment is selected as the tool integration platform.A model-driven tool chain integrating modeling tool AML Editor,semantic reasoning tool Apache Jena,planning and scheduling tool,formal verification tool CPN Tools,automatic control program development and operation tool Eclipse 4diac FORTE,production process simulation tool Coppelia Sim and tool integration platform GME is proposed,which is oriented to the different links between the development process.Unified integration is achieved by implementing model interpreters for different tools.Finally,based on the intelligent production line prototype platform of the intelligent manufacturing laboratory of South China University of Technology,the model-driven tool chain constructed in this paper is used to develop the production line,and it is demonstrated based on specific processing cases.The experimental results verify the rationality and effectiveness of the tool chain for production line development.
