摘要/Abstract

摘要： 针对当前数字孪生车间演化机理不清楚造成其在制造领域技术路线图不明确的问题，从信息流、物料流、控制流三者的作用及关系剖析了当前生产车间所存在的问题和挑战，在总结数字孪生源起与发展现状后，提出从可视化、逻辑、数据三个维度构建可交互、可控制、可计算的虚拟车间，进而探讨从虚拟车间到数字模型车间、数字投影车间和数字孪生车间的演化机理。提出从数字化、智能化、智慧化三个阶段逐步构建数字孪生车间并阐述了各阶段的运行机制及使能技术，可为数字孪生车间在制造领域的推广与应用提供参考。

Abstract: The evolution mechanism of the DTSs was not clear, resulting in a lack of technology roadmap for DTS in the manufacturing fields. To fill this gap, firstly the existing problems and challenges in production shopfloors were analyzed in the view of the role and relationship of information flow, material flow and control flow. Then, after summarizing the research status of digital twin, the method how to construct an interactive, controllable and computable virtual workshop was proposed from three dimensions namely visualization, logic and data. Further,evolution mechanism from virtual shopfloors to digital model shopfloors, digital shadow shopfloors and DTSs was explored. Finally, the DTS was realized from digital, intelligent and smart stages, and the operation mechanism and enabling technologies of each stage were expounded, which provides reference for the promotion and applications of DTS in the manufacturing fields.

Key words: digital twin shopfloor(DTS), evolution mechanism, digital twin, operation mechanism, roadmap
