数字孪生连接交互理论与关键技术

Digital twin, which strives to realize cyber-physical fusion, has made giant strides with its widely applications in various fields. However, a vital issue when utilizing digital twin is how to realize data connection and interaction. To tackle this problem, the connotation and criterion of digital twin connection and interaction were first introduced. Then, a theoretical system of digital twin connection and interaction was proposed from five aspects, including perception, communication, physical-virtual mapping, data-model coupling and fusion. Furthermore, the key technologies from the above five aspects were discussed in detail. Combined with the research on physical entity, digital twin modeling, digital twin data and digital twin service, a theoretical system based on five-dimension digital twin model was enriched, expecting to provide references for the construction and application of digital twin.
