Abstract

The invention discloses a digital twinning system applied to industrial production and a forming method thereof. The digital twinning system applied to industrial production is arranged on the basis of an industrialized intelligent production system, and includes a physical entity layer, a data collection layer, a layer of digital twinning and an information model thereof and a process optimization layer which are sequentially connected. The process optimization layer is also connected with the physical entity layer through feedback control to form a closed loop. The digital twinning system can more intelligently control production, and is suitable for all production and factory affair systems (production equipment and production lines) and monitoring and prediction management systems in use and maintenance.

Description

technical field [0001] The invention belongs to the field of intelligent manufacturing, and relates to a digital twin system, in particular to a digital twin system applied to industrial production and a forming method thereof. Background technique [0002] Digital twin technology originated from NASA's mirror image of the aircraft in the Apollo project and was applied in flight status monitoring. General Electric implemented digital twins on its cloud platform, using advanced technologies such as big data and the Internet of Things to achieve real-time monitoring, timely inspection and predictive maintenance of engines. [0003] The digital twin technology applied to industrial production can open up the technical process from research and development to production, and can use virtual models to simulate unknown fields and designs, and can also avoid safety hazards caused by direct implementation in production. At the same time, the digital twin is a technical means for th...
