标题： RACS2: A Framework of Remote Autonomous Control System for Telescope Observation and its application

摘要： 随着天文学观测需求的增加，望远镜系统变得越来越复杂。因此，天文台控制软件需要更加智能，它们必须控制天文台内的每个仪器，自主完成观测任务，并在需要时向用户报告信息。我们开发了一个名为远程自主控制系统2代（RACS2）的分布式自主天文台控制框架，以满足这些要求。RACS2框架采用去中心化的分布式架构，仪器控制软件和系统服务（如观测控制服务）被实现为不同的组件。组件之间的通信基于高性能序列化库和轻量级消息库实现。实现了面向Python和实验物理与工业控制系统（EPICS）的接口，因此RACS2框架可以与基于EPICS的设备控制软件和基于Python的软件进行通信。开发了几种系统组件，包括日志、执行器、调度器和其他模块，以帮助观测。观测任务可以用Python语言编程，计划由调度器组件进行调度，以实现自主观测。基于FastAPI框架实现了一组Web服务，用户可以通过此进行远程控制和管理该框架。基于RACS2框架，我们已经实现了DATs望远镜的观测系统和空间目标观测系统。我们进行了远程自主观测，并通过这些系统接收了许多数据。 显示英文摘要

摘要： As the demand of astronomical observation rising, the telescope systems are becoming more and more complex. Thus, the observatory control software needs to be more intelligent, they have to control each instrument inside the observatory, finish the observation tasks autonomously, and report the information to users if needed. We developed a distributed autonomous observatory control framework named Remote Autonomous Control System 2nd, RACS2 to meet these requirements. The RACS2 framework uses decentralized distributed architecture, instrument control software and system service such as observation control service are implemented as different components. The communication between components is implemented based on a high-performance serialization library and a light-weighted messaging library.The interfaces towards python and Experimental Physics and Industrial Control System (EPICS) are implemented, so the RACS2 framework can communicate with EPICS based device control software and python-based software. Several system components including log, executor, scheduler and other modules are developed to help observation. Observation tasks can be programmed with python language, and the plans are scheduled by the scheduler component to achieve autonomous observation.A set of web service is implemented based on the FastAPI framework, with which user can control and manage the framework remotely.Based on the RACS2 framework, we have implemented the DATs telescope's observation system and the space object observation system.We performed remote autonomous observation and received many data with these systems.
