【摘要】：为了阅读宇宙边缘的信息,我国研制了500米口径球面射电望远镜(FAST)。FAST将是世界上最大最灵敏的单口径射电望远镜,其三项自主创新开创了建造巨型射电望远镜的新模式。FAST是一架坐落于贵州大窝凼的可动抛物面射电望远镜,其获取的观测数据将服务于宇宙起源和演化、探索生命起源等多科学目标的研究。FAST是一套500米大小的大型设备,观测细节繁琐,需要为观测用户提供一个规范和可视化观测过程的上层、易用接口。要允许用户在观测过程中,实时地查看观测状态和分析观测数据,及时调整观测。FAST可探测的天体高达上亿,为提高观测时间的使用效率和观测数据质量,要能够制定灵活的观测计划,优化天体的观测顺序。FAST未来将开放给全世界用户使用,要对所有用户的观测内容进行管理。因此,FAST需要一个管理用户观测和优化观测序列的观测管理系统(OMS),以此避免观测的失效导致的无效数据所带来的观测时间浪费。结合FAST的建设情况,本课题提出了OMS系统研究方案。从望远镜观测管理和序列优化两大问题展开分析,构建了系统功能结构,包括观测规划、观测调度、观测执行三大子系统。然后对三大子系统进行功能设计,最后通过实现一个原型来验证系统分析和设计的正确性。在国内,为大型射电望远镜开发大型软件系统,很多方面还欠缺相关经验。OMS系统的研发思路包括版本迭代开发、分层架构、模块化设计等,能为FAST其他软件以及完整OMS系统的开发提供借鉴。
[Abstract]:In order to read the information on the edge of the universe, China has developed a 500-meter spherical radio telescope FASTT. Fast will be the largest and most sensitive single aperture radio telescope in the world. Its three independent innovations have created a new model for the construction of giant radio telescopes. Fast is a movable paraboloid radio telescope located in Dawotang, Guizhou. The obtained observation data will serve the origin and evolution of the universe. The research of exploring the origin of life and other multi-scientific targets. Fast is a large equipment with a size of 500 meters. The observation details are cumbersome. There is a need to provide an upper layer and easy-to-use interface for the user to standardize and visualize the observation process. It is necessary to allow the user to view the observation state and analyze the observation data in real time during the observation process. In order to improve the efficiency of observation time and the quality of observation data, it is necessary to formulate flexible observation plan. Optimizing the observational sequence of celestial bodies. Fast will be made available to users around the world in the future, managing all users' observations. FAST needs an observation management system that manages user observations and optimizes observation sequences. In order to avoid the observation of invalid data caused by the failure of observation time waste. Combined with the construction of FAST. In this paper, the research scheme of OMS system is put forward. The system function structure, including observation planning and observation scheduling, is constructed by analyzing the two major problems of telescope observation management and sequence optimization. Observation and execution of the three subsystems. Then the functional design of the three subsystems, finally through the implementation of a prototype to verify the correctness of the system analysis and design. In the domestic. For the development of large software systems for large radio telescopes, many aspects of the lack of experience. OMS system development ideas include version iterative development, hierarchical architecture, modular design and so on. Can provide reference for the development of other FAST software and complete OMS system.
