控制系统是天文望远镜必不可少的重要组成部分。对于大型望远镜来说，高效的控制系统对于成功观测至关重要。在本文中，对大型望远镜控制系统的通用模型及其广泛的共同要求进行了详尽的研究。本文还讨论了基于面向对象分析的基本层次结构、工作流模型和望远镜控制模型，以及通用望远镜的主要数据流模型。经过对这些模型的分析，提出了一种具有广泛适应性的分层正交体系结构。讨论了LAMOST（大天区多目标光纤光谱望远镜）项目和FAST（五百米口径球面射电望远镜）项目中使用的基于消息总线的具体架构设计。本文提出的控制系统设计可为大型望远镜的建设提供有益的参考。
The control system is an essential and important part of an astronomical telescope. For large telescopes, an efficient control system is vital for successful observations. In this paper, an exhaustive study of generic models of control systems for large telescopes and a wide range of their common requirements are presented. This paper also discusses a basic hierarchical structure, workflow model, and telescope control model based on object-oriented analysis, as well as the main data flow model of a general purpose telescope. After analysis of these models, a layered and orthogonal architecture, which has a wide range of adaptability, is proposed. The design of a concrete architecture based on the message bus, which is used in the LAMOST (Large Sky Area Multi-Object Fiber Spectroscopy Telescope) project and FAST (The Five-Hundred-Meter Aperture Spherical Radio Telescope) project, is discussed. The design of the control systems proposed in this paper can serve as a useful reference in the construction of large telescopes.
