摘要
在航空电子系统中,机电系统是飞机的重要组成部分,通过机电系统余度设计可提高系统可靠性。讨论了余度管理技术中的同步技术、交叉传输技术、通道控制逻辑技术和数据容错重构技术,并将这些技术有效运用在分布式双余度机电管理系统中,有效提升了机电系统的数据资源共享能力和容错重构能力。
Electromechanical system is an important part of aircraft in avionics system.The reliability of the system can be improved by redundancy design of the electromechanical system.This paper mainly discusses synchronization technology,cross transmission technology,channel control logic technology,data fault-tolerant and reconfiguration technique in redundancy management technology.The application of these technologies in the distributed dual-redundancy mechanical and electrical management system,which can effectively improve the data resource sharing ability and fault-tolerant reconfiguration ability of airborne electromechanical system.
