摘要
随着新一代信息技术(如云计算、物联网、大数据、移动互联、人工智能等)与制造的融合和落地应用,世界各国相继提出了各自国家层面的制造发展战略。代表性的如工业4.0、工业互联网、基于CPS的制造、中国制造2025和互联网+制造、面向服务的制造或服务型制造等。这些战略虽提出的背景不同,但其共同目标之一是实现制造的物理世界和信息世界的互联互通与智能化操作,其共同瓶颈之一是如何实现制造的物理世界和信息世界之间的交互与共融。针对这一难题,基于数字孪生(Digital Twin),提出了数字孪生车间(Digital Twin Workshop)的概念,阐述了数字孪生车间的系统组成、运行机制、特点、关键技术等。在此基础上探讨了基于车间孪生数据的车间物理世界和信息世界的交互与共融理论和实现方法。
With the integration and extensive applications for new generation of information technologies（such as cloud computing,internet of things,big data,mobile internet,artificial intelligence）in manufacturing industry,a number of countries had put forward their national advanced manufacturing development strategies,such as Industry4.0in Germany,Industrial Internet and manufacturing system based on Cyber-Physical Systems（CPS）in USA,as well as Made in China 2025 and Internet Plus Manufacturing in China.Although each of these strategies was proposed under different circumstances,one of the common purposes of these strategies was to achieve the interconnection,interoperability between physical world and the information world of manufacturing and the intelligent operation of manufacturing.As one of bottlenecks to achieve this purpose,the communication and interaction between the physical world and the information world of manufacturing must be solved.To solve the problem,a novel concept of Digital Twin Workshop（DTW）based on digital twin was proposed.Complementary to the concept,the characteristics,architecture,system composition,operating mechanism and enabling key technologies were also elaborated and discussed respectively.On this basis,the theory and implementation of the communication and interaction between physical and information world of workshop based on workshop digital twin data were discussed.
