【摘要】：甚长基线干涉测量(VLBI:Very Long Baseline Interferometry)是当前天文学使用的一项高分辨率、高测量精度的观测技术,在天体物理、大地测量、地球物理、深空探测等方面应用极为广泛。在最近的十多年间,中国也将此技术应用在了探月工程的“嫦娥卫星”绕月和落月观测任务中。由国内四个VLBI观测台站、五台望远镜和一个数据处理中心组成的中国VLBI网(CVN:Chinese VLBI Net),在对“嫦娥卫星”精确测轨和定轨任务中,发挥了极其重要的作用。作为VLBI重要组成部分的终端记录系统——Mark5B记录系统,其主要功能就是记录海量天文数据,为天文研究提供有价值的资料。由于观测的数据最终都是存放在Mark5B记录系统中,因此,Mark5B记录系统的可靠性和稳定性对于整个观测来说是至关重要的。为了保障观测能够顺利地、可靠地进行,全面了解Mark5B记录系统的实时状态是非常必要的。由于原有的监视系统功能较少、操控性不强,已经不能满足未来观测的需求,因此,我们需要对其进行改进和完善。本研究课题的主要工作就是要设计一套功能完善的Mark5B监控系统软件,通过新的监控系统,能够进一步提高VLBI终端记录系统的可靠性,保障VLBI观测的数据有效和高质量。本研究课题设计的Mark5B监控系统主要功能包括：获取磁盘阵列信息、实时了解数据记录状况和时间同步情况、控制磁盘阵列、传输数据以及Mark5B远程登陆等。论文从研发的软件设计思想、软件的结构、软件的通讯方式、软件功能等几方面进行了详细阐述。本监控软件采用QT开发环境,利用信号和槽的安全类型机制,在QT creator集成开发环境(IDE)上设计人机交互界面并完成数据采集和网络通信。本研究课题的完成,标志着一套将控制、传输和检测合为一体的Mark5B监控系统已经成功地建立,该控制系统不仅操控方便,而且功能完善。乌鲁木齐南山观测站作为CVN网的重要成员,已将该监控系统软件应用于本台站的VLBI终端系统,并且进行了多次观测实验,工作情况良好,达到了预期目标。该监控系统不仅可以应用于VLBI测地和天体物理观测,而且可以应用于CVN的探月“长管”观测和其它课题观测,同时可以将本监控系统作为VLBI台站监控系统的一个补充。
[Abstract]:Very long baseline Interferometry (VLBI:Very Long Baseline Interferometry) is a high-resolution, high-precision observation technique used in astronomy. It is widely used in astrophysics, geodesy, geophysics, deep space exploration and so on. For more than a decade, China has also applied the technique to the lunar orbit and landing missions of the Chang'e satellite, a lunar exploration project. The Chinese VLBI network (CVN:Chinese VLBI Net), which is composed of four VLBI stations, five telescopes and a data processing center in China, plays a very important role in the precise orbit measurement and orbit determination of Chang'e satellite. As an important part of VLBI, the terminal recording system-Mark5B recording system, its main function is to record massive astronomical data and provide valuable information for astronomical research. Because all the observed data are stored in the Mark5B recording system, the reliability and stability of the Mark5B recording system is very important for the whole observation. In order to ensure that the observation can be carried out smoothly and reliably, it is necessary to fully understand the real-time state of the Mark5B recording system. Because the function of the original monitoring system is less and the manipulation is not strong enough to meet the needs of the future observation, we need to improve and perfect the monitoring system. The main work of this study is to design a set of Mark5B monitoring system software with perfect function. Through the new monitoring system, the reliability of the VLBI terminal recording system can be further improved, and the data observed by VLBI can be guaranteed to be effective and high quality. The main functions of the Mark5B monitoring system designed in this paper include: obtaining the information of disk array, understanding the status of data recording and time synchronization in real time, controlling the disk array, transmitting data and logging on Mark5B and so on. In this paper, the software design idea, software structure, software communication mode, software function and so on are described in detail. The monitoring software adopts the QT development environment, uses the security type mechanism of signal and slot, designs the human-computer interface on the QT creator integrated development environment (IDE), and completes the data collection and network communication. The completion of this study indicates that a set of Mark5B monitoring system, which integrates control, transmission and detection, has been successfully established. The control system is not only easy to operate, but also perfect in function. As an important member of CVN network, the monitoring system software of Nanshan Observatory in Urumqi has been applied to the VLBI terminal system of this station. The monitoring system can be applied not only to VLBI geodetic and astrophysical observation, but also to CVN lunar probe "long tube" observation and other subject observations. At the same time, this monitoring system can be used as a supplement to the monitoring system of VLBI station.
