摘要： 传统车间在数据集成与服务方面存在智能化程度低、存储介质和生产介质单一的问题,为了解决这些问题,以数字孪生制造单元为研究对象,提出了面向多视图的数据集成与服务方法。首先,基于开放性生产控制和统一架构信息模型,构建了模型与数据实体之间的映射关系,并通过自组织的数据存储方法实现了制造单元的数据集成。其次,设计了面向多视图应用的表述性状态转移数据服务方法。最后,以数字孪生制造单元中具体的生产应用为案例,验证了所提方法具有更少的数据服务耗时和网络请求次数,可以有效提升数据集成的实时性。

Abstract: 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.

Key words: digital twin, manufacturing cell, multi-view, data integration, date service
