Research on Information Model Construction Technology of Multi-source Heterogeneous Industrial Data Collaborative Management Based on OPC UA
In order to realize unified scheduling and collaborative management of heterogeneous data in various dimensions of the production workshop and integrate heterogeneous data generated by various devices at different levels in the production process,OPC UA communication protocol was used to solve the problem of interconnection of heterogeneous data.On this basis,combined with the characteristics of manufacturing and the architecture of intelligent manufacturing system,a complete and unified information model of production workshop was built to express the cooperative relationship between systems to the greatest extent.The OPC UA server was developed using Python,and the mapping of information model to address space was completed in the server.At the client,the Client/Server architecture was realized and data interaction was completed through reserved API.Finally,a classic scene of a produc-tion line was selected for testing,and the data of mine safety monitoring system and field data collected data were introduced into the instantiation information model.The experimental results show that the information model construction technology based on OPC UA can realize the collaborative management of heterogeneous data.It provides support for big data mining and analysis of intelligent man-ufacturing industry.
