Industrial Internet upgrades the traditional industrial manufacturing to digitization, networking and intellectualization era, which calls for brand-new technology supports. As a promising solution, the emergence Digital Twin (DT) offers enhanced digital mapping capability with strong feasibility, security, economic and intelligence, which fits well with the concept of Industrial Internet. In this paper, we focus on establishing a new reference architecture of DT to support the development of Industrial Internet. It is composed of three interdependent layers (i.e., physical layer, DT layer and DT networks layer) and four critical attributes (i.e., privacy, security, awareness and real-time). We illustrate our perspectives for the functionality and relationship of the three layers, and features and feasible solutions of the four attributes. With those efforts, the proposed DT architecture can provide both smart manufacturing and networked services for Industrial Internet era. Moreover, we also illustrate the relevant and open challenges. Finally, the conclusion and future perspective are pointed out.
工业互联网将传统工业制造提升至数字化、网络化和智能化时代，这需要全新的技术支持。作为一种有前景的解决方案，数字孪生（DT）的出现提供了增强的数字映射能力，具有很强的可行性、安全性、经济性和智能性，与工业互联网的概念非常契合。在本文中，我们专注于建立一种新的数字孪生参考架构，以支持工业互联网的发展。它由三个相互依存的层（即物理层、数字孪生层和数字孪生网络层）和四个关键属性（即隐私、安全、感知和实时）组成。我们阐述了对这三层的功能和关系以及四个属性的特征和可行解决方案的观点。通过这些努力，所提出的数字孪生架构可以为工业互联网时代提供智能制造和网络服务。此外，我们还阐述了相关的开放性挑战。最后，指出了结论和未来展望。
