Problems solved by technology

[0005] However, the inventors found that to accurately model a complete engineering system, a very large computing model is usually required, which requires a large amount of computing resources for evaluation. In many electromechanical equipment application services, digital twins are required to provide near real-time Insights, so that they can be effectively used for operational decision-making, which requires the ability to quickly obtain application service-oriented lightweight models according to different application scenarios of electromechanical equipment, and quickly perform model simulation analysis to provide analysis and prediction services, and now Most of the lightweight model acquisition methods for electromechanical equipment take a long time to solve and lack real-time performance, which hinders the development of digital twins
