摘要
为解决航空电子系统的故障管理问题,提出了一种故障的统一管理、分级处理机制。将系统中故障处理统一配置、集中管理。把故障处理分为5级:进程级、分区级、模块级、子系统级和系统级;每一级设计故障检测、故障过滤和故障处理,故障先发现,后确认,再处理;无法处理的故障交由上一次处理。这种故障处理机制既可以保证故障处理的效率,又可以提高系统的故障处理能力。
To solve the problem of fault management in the aviation electronic system,a kind of fault uniform configuration and hierarchical management mechanism is proposed.All the configuration of the fault handling will focus on the same configuration file and unified management .The fault management system is divided into five stages：process level,partition level,module level,subsystem level and system level. Each level contains fault detection,fault filtering and fault handing.The fault is first detected,then confirmed and finally handled.If it is unable to handle the fault,the fault will be handed over to the upper level for handing.This fault handing mechanism can guarantee the efficiency of handing,and also improve the ability of dealing with the fault.
