无人机飞行控制计算机余度管理软件

针对样例余度配置的无人机飞行控制计算机体系结构,提出了一种输出信息余度管理方案.设计了数据交叉链路通讯、同步、输出信息表决、成员关系计算和系统重构等算法,采用多任务方案实现了相应的余度管理软件.最后,在样例三余度飞行控制计算机上进行了余度管理算法测试,结果表明所提出的方案正确,算法功能与性能满足工程应用要求.

Redundancy Management Software in Flight Control Computer for Unmanned Aerial Vehicle(UAV)

The redundant management software is designed based on the redundant flight control computer of the physical model. The redundant management software focuses on critical algorithms, such as cross data link, time synchronization, voting, membership calculation, and system reconfiguration algorithms. The redundant management software is realized by multi-task schemes. Finally, the redundant management software is tested in redundant flight control computer. Results show that the functionality and the performance meet the application requirements.
