Watch 06 Is there a scientific problem with digital twins?

CP451-50 There are a series of scientific problems and difficulties in the practical application of digital twins in manufacturing and related fields. Around the digital twin five-dimensional model:

① In the physical entity dimension, how to realize intelligent perception and interconnection of multi-source heterogeneous physical entities, obtain multidimensional data of physical entity objects in real time, so as to deeply understand and explore relevant laws and phenomena, and realize reliable control and accurate execution of physical entities;

(2) In the dimension of virtual model, how to build a dynamic multi-dimensional multi-spatio-temporal scale high-fidelity model, how to ensure and verify the consistency/authenticity/validity/reliability of the model and the physical entity, and how to realize the assembly and integration of multi-source and multi-discipline multi-dimensional models;

(3) In the dimension of twin data, how to achieve frequency conversion acquisition of massive CP451-50 big data and abnormally small data, how to achieve efficient transmission of multi-source heterogeneous data of full factor/full service/full process, how to achieve deep fusion and comprehensive processing of information and physical data, how to achieve accurate mapping and real-time interaction of twin data with physical entities, virtual models, services/applications, etc.;

(4) In the connection and interaction dimension, how to achieve cross-protocol/cross-interface/cross-platform real-time interaction, how to achieve data-model-application iterative interaction and dynamic evolution;

CP451-51

In the service/application dimension, how to provide services to meet the needs of different fields, different levels of users and different business applications based on the multidimensional model and twin data, and achieve value-added and efficiency of on-demand use of services?

The above scientific problems are a series of problems that need to be solved urgently in the research and application of digital twins. In addition, in the process of digital twin commercialization, such as the development of commercial platforms and tools, business model promotion and application, there are also some problems to be studied and solved.

Watch 07 digital twin why?

Digital twins build a high-fidelity model consistent with CP451-50 the physical world in the virtual space in the form of digitalization. Through continuous closed-loop information interaction feedback and data fusion with the physical world, they can simulate the behavior of objects in the physical world, monitor the changes in the physical world, reflect the running status of the physical world, evaluate the state of the physical world, and diagnose problems. Predict future trends and even optimize and change the physical world.

The digital twin can break through the limitations of many physical conditions, and realize continuous innovation of services, immediate response to demand and upgrading and optimization of industry through simulation, prediction, monitoring, optimization and control driven by data and model. Based on the advantages of models, data CP451-50 and services, digital twin is becoming a key technology to improve quality, increase efficiency, reduce costs, reduce losses, ensure safety, energy saving and emission reduction, and digital twin application scenarios are gradually extending to more and broader fields. Table 2 lists the specific functions, application scenarios, and functions of digital twins.
