【摘要】：随着人类对宇宙空间的不断探索,空间技术得到迅速的发展,各种空间科学数据也随之产生并日益增加。为了使空间科学数据更好的为人们服务,提供一个空间科学数据服务平台是很必要的。而空间科学数据还有一个特点就是数据量大,可以到TB级别。大量的数据会影响数据服务平台的的响应时间,拖慢整个数据服务平台的速度,使软件系统的友好性下降,用户体验差。为了解决这一问题,本课题要完成REST风格的空间科学数据共享平台。本平台包含数据目录,快速预览,获取数据,系统管理等模块。管理员可以通过此平台进行用户管理,其中包括修改注册用户的身份信息和用户对数据的权限问题;注册用户可以通过这个平台对磁测卫星收集到的各种数据进行查看、下载、可视化,还可以查看元数据信息并下载。论文基于磁测卫星得到的各种空间科学数据,以Python为服务器开发语言,运用Postgre SQL数据库,Ajax技术等探讨了平台的设计与实现。论文首先概述了选择题目的背景、意义及目前的状况。其次按照软件工程的思想,分析了平台的需求,确保开发产品的质量,并对软件的整体架构和模块的详细功能进行了设计。随后,通过代码编写实现了软件的既定需求。最后通过测试,完成对软件功能与性能的衡量。经过测试,软件达到了预期效果,实用性很高。得到了一个独立,灵活,扩展性强,用户体验好,友好性能佳的数据共享服务平台。
[Abstract]:With the continuous exploration of space, space technology has been developed rapidly, and a variety of space science data have been produced and increased day by day. In order to make space science data serve people better, it is necessary to provide a space science data service platform. Space science data is also characterized by a large amount of data, can reach TB level. A large amount of data will affect the response time of the data service platform, slow down the speed of the whole data service platform, reduce the friendliness of the software system and lead to poor user experience. In order to solve this problem, we should complete the rest-style space science data sharing platform. The platform includes data catalog, quick preview, data acquisition, system management and other modules. Administrators can manage users through this platform, including modifying the identity information of registered users and user rights to data; registered users can view and download all kinds of data collected by magnetometric satellites through this platform. Visualize, you can also view metadata information and download. Based on all kinds of space science data obtained from magnetic satellite, this paper discusses the design and implementation of the platform with Python as the server development language and Postgre SQL database Ajax technology. The paper first outlines the background, significance and current situation of the topic selection. Secondly, according to the idea of software engineering, the requirements of the platform are analyzed to ensure the quality of the product, and the overall architecture of the software and the detailed function of the module are designed. Subsequently, the established requirements of the software are realized by code writing. Finally, through the test, complete the software function and performance measurement. After testing, the software has achieved the desired results, and the practicability is very high. An independent, flexible, extensible, user experience and friendly data sharing service platform is obtained.
