Design of Satellite Stowage Data Management System Based on NoSQL Technology

为解决传统星载计算机系统中卫星数据储存速度慢、数据备份不足和综合管理能力弱等问题,设计了基于NoSQL处理技术的卫星配载数据管理系统。系统数据查询模块通过探测帧操作命令,实现了数据的快速检索和快速回传;数据库综合管理模块实现了地对空数据传输、传感器采集模块的数据储存、操作命令的执行和实时通信。为加快数据传输,传输层采用UDP协议,详细进行了储存帧、数据检索帧和数据传输帧的设计。模拟系统实验测试证实该系统能够实现多源数据的快速存取、复杂查询和传输通信。

In order to solve the problems of slow storage speed of satellite data,insufficient data backup and weak comprehensive management ability of traditional onboard computer system,a data management system based on NoSQL processing technology is designed.The data query of the system realizes the fast retrieval and fast return of the data by detecting the frame operation command.The integrated management of database realizes the ground to air data transmission,data storage of sensor acquisition module,execution of operation command and real-time communication.In order to speed up the data transmission,the transport layer adopts UDP protocol,and designs the storage frame,data retrieval frame and data transmission frame in detail.Through the experimental test of the simulation system,it is proved that the system can realize the fast access of multi-source data,complex query and transmission communication.
