容错飞控计算机体系结构研究

Research on Fault-tolerant Flight Control Computer

以无人机容错飞控系统的关键部件——容错飞控计算机为研究对象,提出了一种容错飞控计算机的硬件冗余和软件管理的余度管理设计方法。系统地介绍了容错飞控计算机的硬件体系结构和软件总体架构,并对其关键技术进行了分析。在无人发生故障时,容错飞控计算机能够快速、准确地检测、隔离故障,采取重构策略,确保无人机系统能够继续执行任务或安全返航。

The fault-tolerant flight control computer system for unmanned flight vehicle is introduced. For this research object, a kind of redundancy management strategy based on redundant hardware and software management is presented. The overall hardware and software architecture are systematic discussed and its key technologies are analyzed. The fault-tolerate flight control computer can quickly and accurately detect and isolate the fault, ensure that the UAV system can continue to perform the task or return safely by taking the reconstruction strategies.
