面向多视图的数字孪生制造单元数据集成与服务方法

The traditional workshop has some problems in data integration and service, such as low intelligence degree, single storage medium and single production medium.To solve these problems, a multi-view oriented data integration and service method was proposed by taking digital twin manufacturing cell as the research object.Based on the OPC UA information model, the mapping relationship between the model and the data entity was constructed, and the data integration of the manufacturing unit was realized through the self-organizing data storage method.The data service method based on REST for multi-view application was designed.Taking the specific production application in the digital twin manufacturing cell as an example, the proposed method had less data service time consuming and network request times, and could effectively improve the real-time performance of data integration.
