面向空天地一体化网络的数字孪生系统架构
Digital Twin System Architecture for Space-Air-Ground Integrated Network
摘要
Abstract
With the advantages of three-dimensional coverage and global services,the space-air-ground integrated network has become a major development direction of future networks.However,its urgent deployment requirements,complex network architecture and dynamic topology changes pose enormous challenges to satellite development and network construction.To address these issues,digital twin technology is introduced and a five-dimensional digital twin system model tailored for space-air-ground integrated networks is proposed,clarifying the core connotations of physical entities,virtual entities,twin data,twin services,and connection relationships.Furthermore,a four-layer system architecture comprising the entity layer,resource layer,orchestration layer,and application layer is designed to achieve heterogeneous entity management,global resource scheduling,and intelligent task orchestration.Meanwhile,the functional mechanisms of four core enabling technologies,namely digital simulation,system modeling,artificial intelligence,and big data,are systematically elaborated.The research findings can provide theoretical and practical references for the technical research and engineering implementation of digital twin systems for space-air-ground integrated networks.关键词
