Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a digital twin model based on an industrial Internet cloud platform and a construction method thereof. Background technique [0002] Digital twin is a technical means that integrates multi-physics, multi-scale, and multi-disciplinary attributes, has real-time synchronization, faithful mapping, and high-fidelity characteristics, and can realize the interaction and integration of the physical world and the information world. With the introduction of the concept of digital twin workshop, the application potential of digital twin in intelligent manufacturing has received more and more attention. Specifically, the digital twin is to digitally create a virtual model of a physical entity, use data to simulate the behavior of the physical entity in the real environment, and use virtual and real interactive feedback, data fusion analysis, decision-making iterative opti...

Problems solved by technology

[0004] (1) Lack of systematic digital twin theory / technical support and application guidelines. At present, there is a lack of theory and technology in digital twin model construction, cyber-physical data fusion, interaction and collaboration, etc., resulting in a lack of corresponding solutions in the application process of digital twins. Theoretical and technical support;

[0005] (2) The comparative advantages of digital twin-driven applications are unclear. At present, digital twin applications are basically in their infancy. The comparative advantages brought about by the application of digital twins in product design, manufacturing and services are not clear. The problems that need to be overcome in the application process Questions and techniques are unclear;

[0006] (3) The application in each stage of the product life cycle is not fully analyzed from the three stages of pre-production, production and post-production of the product. The current application of digital twins mainly focuses on post-production aspects such as product operation and maintenance and health management, and needs to be strengthened in production. Application exploration before (such as product design, redesign, optimization design, etc.) and during production (such as assembly, testing / inspection, workshop scheduling and logistics, etc.)
