【摘要】：為了閱讀宇宙邊緣的信息,我國研制了500米口徑球面射電望遠鏡(FAST)。FAST將是世界上最大最靈敏的單口徑射電望遠鏡,其三項自主創(chuàng)新開創(chuàng)了建造巨型射電望遠鏡的新模式。FAST是一架坐落于貴州大窩凼的可動拋物面射電望遠鏡,其獲取的觀測數(shù)據(jù)將服務(wù)于宇宙起源和演化、探索生命起源等多科學(xué)目標的研究。FAST是一套500米大小的大型設(shè)備,觀測細節(jié)繁瑣,需要為觀測用戶提供一個規(guī)范和可視化觀測過程的上層、易用接口。要允許用戶在觀測過程中,實時地查看觀測狀態(tài)和分析觀測數(shù)據(jù),及時調(diào)整觀測。FAST可探測的天體高達上億,為提高觀測時間的使用效率和觀測數(shù)據(jù)質(zhì)量,要能夠制定靈活的觀測計劃,優(yōu)化天體的觀測順序。FAST未來將開放給全世界用戶使用,要對所有用戶的觀測內(nèi)容進行管理。因此,FAST需要一個管理用戶觀測和優(yōu)化觀測序列的觀測管理系統(tǒng)(OMS),以此避免觀測的失效導(dǎo)致的無效數(shù)據(jù)所帶來的觀測時間浪費。結(jié)合FAST的建設(shè)情況,本課題提出了OMS系統(tǒng)研究方案。從望遠鏡觀測管理和序列優(yōu)化兩大問題展開分析,構(gòu)建了系統(tǒng)功能結(jié)構(gòu),包括觀測規(guī)劃、觀測調(diào)度、觀測執(zhí)行三大子系統(tǒng)。然后對三大子系統(tǒng)進行功能設(shè)計,最后通過實現(xiàn)一個原型來驗證系統(tǒng)分析和設(shè)計的正確性。在國內(nèi),為大型射電望遠鏡開發(fā)大型軟件系統(tǒng),很多方面還欠缺相關(guān)經(jīng)驗。OMS系統(tǒng)的研發(fā)思路包括版本迭代開發(fā)、分層架構(gòu)、模塊化設(shè)計等,能為FAST其他軟件以及完整OMS系統(tǒng)的開發(fā)提供借鑒。
[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.
