云南天文台Hα全日面观测数据服务系统

A Service System for Full-disk Hα Solar Observations in the Yunnan Observatory

云南天文台Hα全日面望远镜是云南天文台太阳观测的主要仪器之一。经过十几年的运行,望远镜积累了大量的观测数据,并且这些数据还在以每天1～2Gbyte的速度增长。为了保存这些数据,便于进行数据共享,建立了Hα全日面观测数据服务系统。硬件方面,采用DAS+NAS的存储方案;软件方面采用PHP+MySQL的方案。本系统的基本功能包括数据存储、数据备份、数据查询和数据下载,并已经正常运行了半年左右。介绍了这一系统的设计方案和基本结构。由于这一系统更多的是为澄江1m红外太阳塔的有关系统的设计提供经验和参照,因此在文中相关部分初步讨论了某些针对澄江1m红外太阳塔有关系统的考虑。

A solar Hα telescope capable of full-disk Hα observations is an important instrument for solar research in the Yunnan Observatory.Since several decades ago a huge amount of observational data have been accumulated with this instrument.The data are still being accumulated with a speed of 1G-2G bytes per day.In order to preserve and share the data with other institutions,we have constructed a service system for the full-disk Hα solar observations.The DAS ＋ NAS hardware configuration and the PHP ＋ MySQL software system are adopted.The combinations allow the construction of a reliable,easy-to-maintain,and costeffective system.The service system includes all necessary functions,such as the data storage,data backup,data search,and data download.The entire system is fully functional and has been successfully operated for more than six months.This paper describes the details of the design and structure of the service system.This system is also a preparation for the design of a similar system for observations with the 1m Solar Telescope at Chenjiang.We thus also give some preliminary considerations of the design for the future system.
