摘　　要：针对航空电子系统,通过通用系统管理研究了当系统中出现单点故障时的一种容错重构技术。通用系统管理采用分级故障管理,对不同级别的故障进行检测、识别和处理;对系统中的关键功能模块采用热备份的方式,当主模块发生故障时,将主模块上的任务全部切换到备份模块上去执行;对系统中的通用处理模块则采用温备份的方式,当其中一个模块发生故障时,将故障模块上的任务切换到备份模块上运行,最终降低了系统单点故障引起的失效,提高了系统的可靠性。In this paper,a fault-tolerant reconfiguration technology for avionics system is studied when there is a single point of failure in the system through general system management.General system management adopts hierarchical fault management to detect,identify and handle faults at different levels.Hot backup is adopted for key modules in the system.When the master module fails,all tasks on the master module are switched to the backup module for execution.For the general processing modules in the system,the warm backup mode is adopted.When one of the modules fails,the task on the failed module is switched to the backup module for operation,which ultimately reduces the failure caused by a single point of failure of the system and improves the reliability of the system.
