In order to improve the reliability and fault tolerance of the flight control computer system,redundancy technology is used in this paper.Redundancy management software is the core of the redundancy technology,through redundancy management software can realize system reliability and fault tolerance.This article studies the redundancy management software algorithm,describes a detailed overall design process of the redundancy management software and gives the software design flow of 20ms task,synchronization,signal monitoring and voting.By constructing a closed-loop simulation platform to verify the reliability of the software,the system of three normal channels,in case of cutting a channel,can also normally work,the simulation results show that the software design is reasonable and effective to ensure system reliability and fault tolerance.
