大型射电望远镜数字孪生系统架构设计与应用

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。

Design and application of digital twin system architecture for large radio telescope

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.
