应用SpaceWire网络的航天器分布式存储系统设计
Design of Spacecraft Distributed Storage System Using SpaceWire Network
摘要
Abstract
In view of the development trend of spacecraft data storage requirement diversification, the design of distributed storage system using SpaceWire network is presented.The system is made up of control modules and store modules,and can provide standard SpaceWire interface in physical layer and link layer,and virtual data interface in network layer.It may be identified and addressing with logical address,so the internal network details can be blocked and the payloads in the spacecraft need not to know the change of the network structure of the storage system.When any module fails,the transmission path can be rescheduled to realize the migration of system conG trol and data storage functions.Compared with the design with similar storage requirements and dualGsolidGstate storage system,the interface type and protocol design of distributed storage sysG tem described in this paper are simpler,and with the obvious advantage of system reconfiguraG tion.关键词
