A digital twin is a digital representation of a specific target entity with a data connection that guarantees both physical and virtual states. Synchronization is performed between them at an appropriate rate and precision. This is because digital twins possess the capabilities of virtual-real fusion and real-time interaction, iterative operation and optimization, and full... With its features of being driven by data from all elements, processes, and business operations, it has been widely applied in various fields such as manufacturing, urban development, agriculture, energy, and construction. Given the widespread application of digital twins in various scenarios, standardization efforts for digital twins are particularly important. GB/T 43441 The aim is to define the general requirements for digital twins, the construction of digital entities, information interaction, and the classification and management of digital assets. It is proposed to consist of four parts. constitute.

1.General Requirements. The purpose is to specify the reference architecture, basic requirements, functional requirements, and security requirements for digital twins.

2.Digital Entities. The purpose is to standardize the architecture, construction, management, and service invocation requirements of digital entities.

3.Information Interaction. The aim is to standardize the conceptual framework for information interaction in digital twins, as well as the main processes such as measurement and perception.

4.Digital Asset Classification and Management Requirements. The purpose is to define the classification of digital assets generated during the digital twin process. and management requirements. Information Technology Digital Twins Part

1 Scope

GB/T 43441.3-2026 is the Chinese national standard covering how a digital twin exchanges information - with the physical thing it mirrors, with other twins and with the applications that use it, including the synchronisation, the events and the security of that traffic. Part 3 of the series, first edition, with Part 2 on the digital entity. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document presents a conceptual framework for digital twin information interaction, specifying measurement and sensing, feedback control, service invocation, and data processing within this framework. Requirements for output, interaction within digital entities, and interaction between digital entities. This document applies to the development, application, and services of digital twin-related systems or products.
