Description

Technical Field

[0001] This invention relates to the field of industrial automatic control technology, and more specifically, to a collaborative construction and simulation system for digital twins of industrial internet platform equipment. Background Technology

[0002] Driven by the wave of industrialization and intelligent manufacturing, industrial internet platforms, as the core carriers for realizing intelligent equipment management, have made equipment digital twin technology a key to enhancing enterprise competitiveness. Equipment digital twins aim to map physical equipment throughout its entire lifecycle using virtual models, providing data and decision support for multi-entity collaborative management.

[0003] As industrial systems become increasingly complex, equipment management involves multiple stakeholders, including equipment manufacturers, maintenance providers, and R&D teams. The data and knowledge generated by each stakeholder at different stages have unique value. Equipment manufacturers possess the 3D models and process parameters from the design phase, maintenance providers accumulate fault data and maintenance records during equipment operation, and R&D teams focus on performance optimization and technological upgrades.

[0004] However, the construction of digital twins for devices in existing systems often relies on a single data source or an independent entity, lacking a cross-entity collaborative configuration mechanism. This data silo phenomenon makes it difficult for different entities to share model resources, leading to problems such as missing information or redundant modeling during the construction of digital twins.

[0005] From a simulation application perspective, real-time data generated during equipment operation (such as temperature, vibration, and energy consumption) is crucial for verifying and optimizing digital twin models. However, due to technical bottlenecks such as inconsistent data transmission protocols and incompatible interface standards, there is a lag in the interaction between real-time equipment operation data and the model during simulation. When physical equipment experiences abnormal operating conditions, the digital twin cannot update its status in a timely manner, leading to delays in fault warning and diagnosis, and hindering efficient collaborative operation between the digital twin and the physical equipment. These issues directly restrict the accuracy and efficiency of equipment management, making it difficult to meet the needs of industrial internet platforms for refined management of the entire equipment lifecycle.

[0006] In view of this, we propose a collaborative construction and simulation system for digital twins of industrial internet platform equipment. Summary of the Invention
