综合航电系统故障处理机制研究

故障处理是综合航电系统的一项关键技术,关系到综合航电系统甚至战机的安全性、维修性和可靠性等诸多方面.总结概括了综合航电系统的特点,分析明确了其对故障处理的需求.针对机上实时故障处理的要求,采用分层处理、统一管理的策略,设计了一种分层的故障处理机制——从设备层、综合区域层和航电系统层三个层次分别进行故障处理的流程设计和所需的蓝图设计,并对故障处理各个阶段采取的策略进行了说明和讨论.最后,就下一步需要研究和解决的问题进行了探讨.

Research on Fault Disposal Mechanism of Integrated Modular Avionics System

Fault disposal is a key technology of integrated modular avionics (IMA) system,which is great important for safety,maintainability and reliability of IMA system and the whole aircraft system.The characteristics of IMA system are summarized,and the requirements of fault disposal are analyzed and specified.Aiming at the real-time requirements for on-vehicle fault disposal,a strategy of hierarchy disposal and uniform configuration is adopted to design a kind of layered fault disposal mechanism,in which the process designs of device level,integration area level and avionics system level and the needful blueprint design are completed.And the strategies of each stage of fault disposal are illustrated and discussed.In the end,some problems that need to be studied and solved in the future are presented.
