摘    要:分析了基于XML进行软件设计的方法,并在乌鲁木齐天文站的数字钟软硬件改造中成功地运用了该方法。给出了天线控制程序中时间采集的基本方法。使用FT206数字钟,在计算世纪数时淘汰了复杂的数学公式,年月日的计算直接从儒略日推算,避免了天线控制计算机设置UT时间的复杂性。运用了基于XML的设计方法,使各种软件设计方法得以统一,便利交流和协作,容易发布,方便软件设计师和程序员协作,使基于Internet的软件开发模式成为可能。最后展望了基于 XML的设计方法的发展趋势。

关 键 词:天文软件  数字钟  儒略日  XML

Abstract:XML-based method for standardization of software designing is introduced and analyzed and successfully applied to renovating the hardware and software of the digital clock at Urumqi Astronomical Station. Basic strategy for eliciting time information from the new digital clock of FT206 in the antenna control program is introduced. By FT206, the need to compute how many centuries passed since a certain day with sophisticated formulas is eliminated and it is no longer necessary to set right UT time for the computer holding control over antenna because the informations about year, month, day are all deduced from Julian day dwelling in FT206, rather than from computer time. With XML based method and standard for software designing, various existing designing methods are unified, communications and collaborations between developers are facilitated, and thus Internet-based mode of developing software becomes possible. The trend of development of XML-based designing method is predicted.
Keywords:astronomy software - digital clock - Julian Day - XML
