摘　　要：为提高大型射电望远镜的自动化管理程度、增强其运维的实时性和操控的交互性,参考数字孪生经典理论模型,提出一种以智能感知为基本处理单元的数字孪生系统实时操控模型,并对其关键技术进行了阐述。以500 m口径球面射电望远镜(中国天眼)为应用案例设计开发了中国天眼数字孪生系统,并对其中的虚拟三维模型创建、数据的智能感知以及虚拟模型的实时驱动等方法进行了分析。最后,通过实验验证了该理论模型的合理性和有效性,为实时管控中国天眼提供了一种新方法。To improve the degree of automatic management for large radio telescope,and enhance the real time and interactivity of its operation and maintenance,a real-time control model of digital twin system based on intelligent perception was proposed,and the key technologies of the digital twin system was described.Taking Five-Hundred-Meter Aperture Spherical Radio Telescope(FAST)as an application case,the digital twin system of FAST was designed and developed,and the virtual model creation,the data intelligent perception and the real-time driving of virtual model were analyzed.The experiment was carried out with part of the system of FAST,which proved rationality and effectiveness of the six-layer theoretical model,and provided an idea for real-time supervision of FAST.
