Abstract天文学是以观测为基础的科学。中国科学院云南天文台2.4m望远镜作为目前中国乃至东亚最大的光学望远镜,其观测数据在整个天文学的发展中有着重要的作用。从2008年10月份到现在为止,2.4m累积的原始观测数据已经达到600GB左右。天文学家要想从这么多的数据中找到符合条件的观测数据单靠人力去搜索是极其困难的,因此为了提高科研工作者的效率,必须开发一套2.4m观测数据的数据管理系统。 数据管理系统不仅是管理数据和挖掘数据信息的有力工具,也是未来远程观测和虚拟天文台的应用基础,因此具有基础性及前瞻性的地位。 本文设计了2.4m数据管理系统的初步框架,并实现了其中的基本功能(如数据的入库、查询、管理、维护等)。经多次调试后目前能够得到稳定运行,以后将逐步完善系统的各个细节和整体的功能。本文所设计的数据管理系统作为远程观测系统的一部分,可以实现观测数据的自动归档,入库。此外,还提供了以往观测数据的共享,即观测数据的查询,下载等。 本文也初步实现了观测数据的远程备份,从而进一步有效地加强了数据的安全性。 本文有四个部分组成: 第一章介绍国内外天文研究的背景、远程观测系统、虚拟天文台 第二章介绍2.4m数据管理系统以及远程备份系统的设计 第三章介绍2.4m数据管理系统的实现及远程备份系统的运行结果 第四章对本文做了总结和未来工作展望
Other AbstractAstronomy is the science based on the observing data. The 2.4 meters telescope of Yun Nan Observatory is the largest optics telescope in China or even in East Asia as yet, so its observing data play an important part at the development of astronomy. So far from 10/2008, the accumulated raw data of observing have reached about 600GB. It is very difficult to get the details of observing data satisfying some conditions only through manual work from so much data. In order to improvement efficiency of the astronomers and save their time of collecting data, it is necessary to develop the 2.4m data management system. Data management system is not only the powerful tool to manage and mine data, it is also an application fundament of the remote observing and the virtual observatory in future, so it takes the fundamental and foremost position. This article has designed the preliminary frame of the 2.4m data manage system including the basic functions(such as the data of archiving, querying, managing and maintaining). Now it can running stably through some testing before. Later on I will complete some functions of detail and entirety step by step. The 2.4m data manage system as the part of 2.4m remote observing system, can realize the function of auto-archiving. In addition, it also provides the past-observing data to share, including the functions of data querying and downloading. This article has also basically realized the function of remote data-replicating. For that matter, we have reinforced the security of the observing data further more. This article mainly consist of four parts:  First of all, it introduces the background of astronomy, remote observing system, and the virtual observatory  Second part introduce primary designs about the 2.4m data manage system and the remote observing system  Third part introduce the realizations of the 2.4m data manage system and some results of the remote observing system  Finally, it is the summary of the article and the outlook of the future
