【摘要】：本文以我國(guó)明安圖超寬頻譜日像儀(Mingantu Ultrawide Spectral Radio Heliograph,MUSER)的數(shù)據(jù)處理為研究背景,對(duì)MUSER數(shù)據(jù)處理所必需的各類(lèi)數(shù)據(jù)的實(shí)時(shí)采集與融合處理進(jìn)行了研究,主要完成的工作包括以下三個(gè)方面：一、實(shí)現(xiàn)了異構(gòu)數(shù)據(jù)的實(shí)時(shí)采集問(wèn)題；MUSER的數(shù)據(jù)處理,必須需要依賴于一系列重要的實(shí)時(shí)參數(shù),包括天線位置數(shù)據(jù)、光纖數(shù)據(jù)、天線狀態(tài)與接收機(jī)狀態(tài)數(shù)據(jù)、氣象數(shù)據(jù)等。本文分析討論了不同設(shè)備的參數(shù)讀取方法,給出了這些數(shù)據(jù)的采集方法和采集的思路與想法；二、設(shè)計(jì)并實(shí)現(xiàn)了異構(gòu)觀測(cè)數(shù)據(jù)的融合系統(tǒng)原型；由于采樣頻率不同,數(shù)據(jù)格式不同,給MUSER這些參數(shù)的融合帶來(lái)了困難。本文基于ZeroMQ技術(shù),對(duì)異構(gòu)數(shù)據(jù)的融合進(jìn)行了研究,為后續(xù)的MUSER數(shù)據(jù)處理系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)提供基礎(chǔ)研究；三、在上述研究的基礎(chǔ)上,分析、設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)異構(gòu)數(shù)據(jù)融合的實(shí)例,通過(guò)提取融合數(shù)據(jù),生成在射電天文數(shù)據(jù)存儲(chǔ)中最為常用的UVFITS文件。對(duì)文件的實(shí)踐表明,提取的數(shù)據(jù)是正確的,UVFITS文件可以被其它科學(xué)軟件所處理。從整體來(lái)看,本文利用計(jì)算機(jī)信息領(lǐng)域的異構(gòu)數(shù)據(jù)融合技術(shù),解決了實(shí)時(shí)異構(gòu)數(shù)據(jù)的采集與融合關(guān)鍵問(wèn)題,保證了MUSER數(shù)據(jù)處理系統(tǒng)的建設(shè)。同時(shí),本文的研究工作是射電天文望遠(yuǎn)鏡建設(shè)的共性工作,對(duì)其它望遠(yuǎn)鏡的建設(shè)也有一定的參考價(jià)值。
[Abstract]:In this paper, based on the data processing of Mingantu Ultrawide Spectral Radio Heliographer (Mingantu Ultrawide Spectral Radio Heliographer), the real-time acquisition and fusion of all kinds of data necessary for MUSER data processing are studied. The main work includes the following three aspects: first, the realization of heterogeneous data real-time acquisition problem MUSER data processing, must rely on a series of important real-time parameters, including antenna position data, fiber data, Antenna state and receiver state data, meteorological data, etc. This paper analyzes and discusses the parameter reading methods of different equipments, and gives the methods of collecting these data and the ideas of collecting them. Secondly, the prototype of the fusion system of heterogeneous observation data is designed and realized. Different data formats make it difficult for MUSER to merge these parameters. Based on ZeroMQ technology, this paper studies the integration of heterogeneous data, which provides the basic research for the design and implementation of the subsequent MUSER data processing system. An example of heterogeneous data fusion is designed and implemented. By extracting the fused data, the most commonly used UVFITS files in radio astronomical data storage are generated. The practice shows that the extracted data is correct and can be processed by other scientific software. On the whole, this paper solves the key problem of real-time heterogeneous data acquisition and fusion by using heterogeneous data fusion technology in the field of computer information, and ensures the construction of MUSER data processing system. At the same time, the research work of this paper is the common work of radio astronomical telescope construction, and also has certain reference value to the construction of other telescopes.
