Design and Implementation of Scalable Autonomous Centralized Fault-Tolerant Scheme for Satellite System
Depending on application requirements,the number of processing nodes in parallel satellite system varies.Currently,fault-tolerant design for satellite system often aims to solve specific problems,lacking in universality.This paper presents a sealable autonomous centralized fault-tolerant (SACFt) architecture.Based on it,functional module framework of each system node and autonomous fault-tolerant strategy are designed.This scheme is insensitive to scale change of the processing nodes.It can ensure autonomous fault tolerance and control node parallelism on demand flexibly at the same time,balancing system reliability,scalability,autonomy,real-time feature and many other factors.The validity and real-time feature of the proposed scheme has been verified and evaluated on the prototype system.
