星载多源数据的分布式存储与快速检索系统设计

Design of Distributed Storage and Fast Retrieval System for Satellite Multi-source Data

基于国产嵌入式操作系统和PowerPC处理器研究并设计了一种面向星载的多源数据分布式存储与快速数据检索管理系统,满足航天器平台对数据灵活存储、检索的设计需求。该系统基于新型Nosql数据库研发星载数据的高效存储管理技术,并结合Sqlite技术设计了基于分布式的星载综合数据查询模块,实现以分布式方式高效管理多源星载数据,便于综合数据管理中心实时快速查询和传输需要的数据,为构建高性能、低功耗的星载分布式数据管理系统提供关键技术支撑。

Based on the domestic embedded operating system and PowerPC processor,a distributed storage and fast data retrieval management system for on-board multi-source data is designed,which meets the design requirements for flexible storage and retrieval of data on spacecraft platforms.The system is based on Nosql database to develop efficient storage and management technology of on-board data. Combined with Sqlite technology,a distributed on-board integrated data query module is designed to efficiently manage multi-source onboard data in a distributed way,which is convenient for the integrated data management center to query and transmit needed data in real time and quickly.It provides key technical support for the construction of high performance and low power satellite distributed data management system.
