Digital twin for Industrial Internet.

Area of Science:

• Industrial Internet
• Digital Twin technology
• Manufacturing systems

Background:

• Traditional industrial manufacturing is evolving towards digitization, networking, and intellectualization.
• The Industrial Internet necessitates advanced technological support for this transformation.
• Digital Twin (DT) technology emerges as a key enabler, offering robust digital mapping capabilities.

Purpose of the Study:

• To establish a novel reference architecture for Digital Twin (DT) systems.
• To support the integration and development of the Industrial Internet.
• To address the technological requirements of smart manufacturing and networked services.

Main Methods:

• Proposing a three-layer interdependent architecture: physical layer, DT layer, and DT networks layer.
• Integrating four critical attributes: privacy, security, awareness, and real-time performance.
• Illustrating the functionality, relationships between layers, and solutions for attributes.

Main Results:

• The developed DT architecture provides a framework for smart manufacturing.
• It enables comprehensive networked services tailored for the Industrial Internet era.
• The architecture addresses key attributes like security and real-time data processing.

Conclusions:

• The proposed Digital Twin architecture is well-suited for the Industrial Internet.
• It facilitates enhanced digital mapping and intelligent industrial operations.
• Future research directions and open challenges are identified.
