Embodiment 1
[0049] figure 1 It is a flow chart of a microservice-based digital twin construction method according to an embodiment of this application. This embodiment is based on the "tetrahedron model", which decomposes the digital twin into four major components: ontology, knowledge body, data body and data portal.
[0050] Such as figure 1 As shown, the digital twin construction method provided in this embodiment includes the following steps:
[0051] S1. Perform component-level decomposition to obtain multiple components that constitute the digital twin corresponding to the physical entity.
[0052] That is to clarify the ontology, knowledge body, data body and data portal included in the digital twin. When constructing ontology, consider the overall system, clarify the classification of physical entities, list the parts of physical entities as components of ontology, and establish the connection of components in ontology.
[0053] The construction of the body of knowledge refers...
Embodiment 2
[0123] image 3 It is a block diagram of a microservice-based digital twin construction system according to the embodiment of this application.
[0124] Such as image 3 As shown, the digital twin building system provided in this embodiment includes a first decomposition module 10 , a second decomposition module 20 , a third decomposition module 30 and a construction execution module 40 .
[0125] The first decomposition module is used to perform component-level decomposition to obtain multiple components constituting the digital twin corresponding to the physical entity.
[0126] That is to clarify the ontology, knowledge body, data body and data portal included in the digital twin. When constructing ontology, consider the overall system, clarify the classification of physical entities, list the parts of physical entities as components of ontology, and establish the connection of components in ontology.

Abstract
The invention discloses a digital twinning body construction method and system based on micro-service, and the method specifically comprises the steps: sequentially carrying out the multi-level decomposition of a digital twinning body corresponding to a physical entity, and obtaining a plurality of assemblies forming the digital twinning body, a plurality of function modules of each assembly, anda plurality of particles needed by each function module; all the particles supporting micro-service; all the particles forming functional modules under the leading of management particles, the functional modules communicating with one another to form assemblies, and all the assemblies being combined to form a digital twinning body of a physical entity. According to the scheme, a clear thought, method and specific implementation steps are provided for establishing the digital twinning body of the physical entity in the digital space, the feasibility is very high, and the construction of the digital twinning body, internal communication of the digital twinning body and safe, rapid and light-weight information interaction with the outside can be completely realized; model architecture supportis provided for large-scale development and deployment of digital twinning applications, interconnection and intercommunication of data become reality, and therefore real landing of digital twinningis promoted.
Description
technical field [0001] The present application relates to the technical field of digital twins, and more specifically, relates to a method and system for constructing a microservice-based digital twin. Background technique [0002] The original concept of digital twin was proposed by Professor Michael Grieves in 2003, but it was not taken seriously at that time. Until 2011, the U.S. Air Force Research Laboratory (AFRI) officially disclosed the guiding ideology of digital twins in a speech. In the same year, AFRI and NASA jointly proposed to build a digital twin of future aircraft, and defined the digital twin as a highly integrated multi-physics, multi-scale, and multi-probability simulation model that can utilize physical models, sensor data and historical data. Data, etc. reflect the function, real-time status and evolution process of the corresponding physical equipment in the virtual space. [0003] Since then, digital twins have been widely concerned by the industry a...
