航空电子设备对可靠性的要求越来越高,文章介绍了一种双主机冗余显示控制系统,并且详细介绍了系统的架构和冗余管理策略。本系统具有故障检测、自动切换控制的能力,可以保证系统稳定、连续的工作。双主机冗余设计增加了系统成本,但在一定程度上提高了系统的可靠性、稳定性,满足航空电子产品对可靠性的要求。 Avionics equipment requires more and more reliability. This paper introduces a dual host redundancy display control system, and introduces the system architecture and redundancy management strategy in detail. The system has fault detection, automatic switching control of the ability to ensure stable system, continuous work. Dual host redundancy design increases the system cost, but to a certain extent, improves the reliability and stability of the system to meet the reliability requirements of avionics.
