Design and Implementation of Satellite-carried Embedded Fault-tolerant File System
摘要
Abstract
The reliability of data in satellite-carried embedded system is important, however, energetic particle will lead to mistake of memory with the complex and volatile space environment. The normal operation of satellite-carried system is impacted. A fault-tolerant scheme based on file system in satellite-carried embedded system is presented in this paper according to the mistake of storage data and damaged equipment appeared in the memory under space environment. The triple module redundancy and the compare fault-tolerant in sectors of embedded file system are utilized in this project. And the fault-tolerant dispose is proceeding respectively to the problem of fault data in the reading and writing. The issue of mistake of storage data in satellite-carried system under the space environment can be solved effectively by using this method via repetitive experiments. And the demand of data which is volume,multi-type and real-time preserved long-distance on orbit can be satisfied,as well as the reliability of data in satellite-carried embedded system.关键词
