【摘要】：本文以我国明安图超宽频谱日像仪(Mingantu Ultrawide Spectral Radio Heliograph,MUSER)的数据处理为研究背景,对MUSER数据处理所必需的各类数据的实时采集与融合处理进行了研究,主要完成的工作包括以下三个方面：一、实现了异构数据的实时采集问题；MUSER的数据处理,必须需要依赖于一系列重要的实时参数,包括天线位置数据、光纤数据、天线状态与接收机状态数据、气象数据等。本文分析讨论了不同设备的参数读取方法,给出了这些数据的采集方法和采集的思路与想法；二、设计并实现了异构观测数据的融合系统原型；由于采样频率不同,数据格式不同,给MUSER这些参数的融合带来了困难。本文基于ZeroMQ技术,对异构数据的融合进行了研究,为后续的MUSER数据处理系统的设计实现提供基础研究；三、在上述研究的基础上,分析、设计并实现了一个异构数据融合的实例,通过提取融合数据,生成在射电天文数据存储中最为常用的UVFITS文件。对文件的实践表明,提取的数据是正确的,UVFITS文件可以被其它科学软件所处理。从整体来看,本文利用计算机信息领域的异构数据融合技术,解决了实时异构数据的采集与融合关键问题,保证了MUSER数据处理系统的建设。同时,本文的研究工作是射电天文望远镜建设的共性工作,对其它望远镜的建设也有一定的参考价值。
[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.
