【摘要】：甚長(zhǎng)基線干涉測(cè)量(VLBI:Very Long Baseline Interferometry)是當(dāng)前天文學(xué)使用的一項(xiàng)高分辨率、高測(cè)量精度的觀測(cè)技術(shù),在天體物理、大地測(cè)量、地球物理、深空探測(cè)等方面應(yīng)用極為廣泛。在最近的十多年間,中國(guó)也將此技術(shù)應(yīng)用在了探月工程的“嫦娥衛(wèi)星”繞月和落月觀測(cè)任務(wù)中。由國(guó)內(nèi)四個(gè)VLBI觀測(cè)臺(tái)站、五臺(tái)望遠(yuǎn)鏡和一個(gè)數(shù)據(jù)處理中心組成的中國(guó)VLBI網(wǎng)(CVN:Chinese VLBI Net),在對(duì)“嫦娥衛(wèi)星”精確測(cè)軌和定軌任務(wù)中,發(fā)揮了極其重要的作用。作為VLBI重要組成部分的終端記錄系統(tǒng)——Mark5B記錄系統(tǒng),其主要功能就是記錄海量天文數(shù)據(jù),為天文研究提供有價(jià)值的資料。由于觀測(cè)的數(shù)據(jù)最終都是存放在Mark5B記錄系統(tǒng)中,因此,Mark5B記錄系統(tǒng)的可靠性和穩(wěn)定性對(duì)于整個(gè)觀測(cè)來(lái)說(shuō)是至關(guān)重要的。為了保障觀測(cè)能夠順利地、可靠地進(jìn)行,全面了解Mark5B記錄系統(tǒng)的實(shí)時(shí)狀態(tài)是非常必要的。由于原有的監(jiān)視系統(tǒng)功能較少、操控性不強(qiáng),已經(jīng)不能滿足未來(lái)觀測(cè)的需求,因此,我們需要對(duì)其進(jìn)行改進(jìn)和完善。本研究課題的主要工作就是要設(shè)計(jì)一套功能完善的Mark5B監(jiān)控系統(tǒng)軟件,通過(guò)新的監(jiān)控系統(tǒng),能夠進(jìn)一步提高VLBI終端記錄系統(tǒng)的可靠性,保障VLBI觀測(cè)的數(shù)據(jù)有效和高質(zhì)量。本研究課題設(shè)計(jì)的Mark5B監(jiān)控系統(tǒng)主要功能包括：獲取磁盤陣列信息、實(shí)時(shí)了解數(shù)據(jù)記錄狀況和時(shí)間同步情況、控制磁盤陣列、傳輸數(shù)據(jù)以及Mark5B遠(yuǎn)程登陸等。論文從研發(fā)的軟件設(shè)計(jì)思想、軟件的結(jié)構(gòu)、軟件的通訊方式、軟件功能等幾方面進(jìn)行了詳細(xì)闡述。本監(jiān)控軟件采用QT開發(fā)環(huán)境,利用信號(hào)和槽的安全類型機(jī)制,在QT creator集成開發(fā)環(huán)境(IDE)上設(shè)計(jì)人機(jī)交互界面并完成數(shù)據(jù)采集和網(wǎng)絡(luò)通信。本研究課題的完成,標(biāo)志著一套將控制、傳輸和檢測(cè)合為一體的Mark5B監(jiān)控系統(tǒng)已經(jīng)成功地建立,該控制系統(tǒng)不僅操控方便,而且功能完善。烏魯木齊南山觀測(cè)站作為CVN網(wǎng)的重要成員,已將該監(jiān)控系統(tǒng)軟件應(yīng)用于本臺(tái)站的VLBI終端系統(tǒng),并且進(jìn)行了多次觀測(cè)實(shí)驗(yàn),工作情況良好,達(dá)到了預(yù)期目標(biāo)。該監(jiān)控系統(tǒng)不僅可以應(yīng)用于VLBI測(cè)地和天體物理觀測(cè),而且可以應(yīng)用于CVN的探月“長(zhǎng)管”觀測(cè)和其它課題觀測(cè),同時(shí)可以將本監(jiān)控系統(tǒng)作為VLBI臺(tái)站監(jiān)控系統(tǒng)的一個(gè)補(bǔ)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.
