摘　　要：机电管理系统是飞机的重要组成部分,支撑着飞机的安全稳定飞行,针对机电管理系统高性能、高稳定的架构需求,提出了一种四节点余度设计。采用分布式容错结构,依靠高速总线通信技术,实现不同节点间的交叉互连与信息共享,从而有针对性地进行余度决策,一定程度上规避失效风险,保证对机载机电设备的感应与制动。Electromechanical management system is an important component of aircraft,supporting the safe and stable flight of aircraft.Aiming at the high-performance and stable architecture requirements of electromechanical management system,this paper proposes a four-node redundancy design.Adopting a distributed fault-tolerant architecture and relying on high-speed bus communication technology,it achieves cross interconnection and information sharing between different nodes,thereby making targeted redundancy decisions,avoiding failure risks to a certain extent,and ensuring the induction and braking of airborne electromechanical equipment.
