Abstract: 数字孪生车间作为实现制造物理世界和信息世界智能互联与交互融合的一种潜在的有效途径,近期被国内外相关领域学术界和企业界高度关注。基于前期对数字孪生车间的概念、系统组成、运行机制、特点和关键技术等研究,设计了数字孪生车间的参考系统架构,并从数字孪生车间4个主要系统组成(物理车间、虚拟车间、车间孪生数据、车间服务系统)的角度出发,分别对物理车间异构要素融合、虚拟车间多维模型融合、车间物理—信息数据融合、车间服务/应用融合等关键问题进行了研究分析。从物理融合、模型融合、数据融合和服务融合4个维度,系统地探讨了实现数字孪生车间信息物理融合的基础理论与关键技术,为企业实践数字孪生车间提供了参考。
As a potential way to realize the interaction and integration between manufacturing physical world and information space, the concept of Digital Twin Shop-floor (DTS) had been proposed recently which attracted high attentions of both academics and industrial practitioners in related fields. Based on the authors' previous work on DTS's concept, system composition, operation mechanisms, characteristics and key technologies, a reference architecture for DTS system was designed. According to the four main system compositions of DTS, the cyber-physical fusion problem was investigated from the following four aspects which were physical elements connection and fusion in physical shop-floor, virtual models integration and fusion in virtual shop-floor, physical-cyber data integration and fusion based on digital twin, and applications integration based on services. The basic theories and key technologies for implementing the four issues of cyber-physical fusion were investigated respectively, which provided a reference for enterprises to build and practice DTS.
