随着国际上天文项目的发展与推进，天文数据呈爆炸式增长。如何从浩瀚如海的大数据集中快速检索所需信息，已成为各国科研人员共同面对的问题。虚拟天文台(Virtual Observatory, VO)为满足对大规模天文数据进行处理分析、检索访问和共享发布等需求，提供了一系列VO标准协议和集成化服务。开发符合VO标准协议的天文数据发布与检索系统、集成数据访问发布和可视化分析服务，符合当前的发展趋势。本文在回顾VO发展历程的基础上，对VO体系结构、VO标准协议等若干关键技术进行概括阐述。同时，基于VO的技术框架，提出硬X射线调制望远镜(Hard X-ray Modulation Telescope，HXMT)卫星数据发布与检索系统的初步设想，设计符合卫星任务需求的体系结构，并选取相关的VO标准协议加以实现。

With the explosive growth of astronomical data, it’s required to constitute uniifed standards for data sharing. Virtual Observatory (VO) provides a series of standard protocols and services to achieve quick retrieval, high performance computing and collaborative resource sharing. Constructing the astronomical data publishing and retrieval system in accordance with VO standards is of great significance in astronomy. This paper reviews the development of VO and elaborates the VO architecture, VO standards and other relevant technologies. Meanwhile, it describes the preliminary design of HXMT data publishing and retrieval system based on VO, including VO standards selection, architecture design and so on.
