面向FAST科学数据管理系统平台的设计与实现

为了对大规模脉冲星及暂现源数据处理技术运用研究的突破,为国家大科学工程FAST实现提供有效的技术支持,加速在脉冲星和暂现源科学研究方面科研成果的产出。尽可能详细记录脉冲星科研数据处理结果,解决数据分析处理过程、科研结果不便于管理、共享等问题。FAST早期科学数据中心设计开发了面向FAST的脉冲星科学数据管理平台。讨论了系统平台的架构设计、功能设计和数据设计,解释了关键技术手段,展示了相关重要功能的实现。基本建成面向FAST科学数据管理平台(http://psrcat.net/),实现了FAST天文望远镜数据资源及相关基础数据资源的科学存储管理,实现了候选体数据与已知脉冲星比对分析和数据可视化展示,收录了来自FAST的优质候选体记录141条,已知脉冲星数据记录2700条,望远镜设备数据20条,相关数据有望为FAST开展新脉冲星搜寻项目制定巡天计划、认证提供数据支撑。

Design and Implementation of FAST Scientific Data Management System Platform

In order to make breakthroughs in the application of large-scale pulsars and transient source data processing technology,it provides effective technical support for the FAST implementation of national Science Project,and speeds up the output of scien?tific research achievements in the scientific research of pulsars and transient source.Record the processing results of pulsar scientif?ic research data in detail as much as possible,so as to solve the problems of data analysis and processing process,and the inconve?nient management and sharing of scientific research results.FAST Early Science Data Center Design develops a pulsar science data management platform for FAST.Built for FAST basic scientific data management platform(http://psrcat.net/),which has realized FAST telescope data resources and related basic data resources,scientific storage management,implement the candidate data com?parison analysis and data visualization display and the known pulsars,and features high quality candidates from the FAST record 141,the known pulsars data record 2700 article,article 20 telescope equipment data,the relevant data is expected to provide FAST to start a new pulsar search project survey plan,certification to provide data support.
