A method is provided for diagnosing a failure on an aircraft that includes aircraft systems configured to report faults to an onboard reasoner. The method includes receiving a fault report at an onboard computer of the aircraft from an aircraft system of the aircraft systems, the fault report indicating failed tests reported by the aircraft system. The onboard reasoner accesses an onboard diagnostic causal model represented by a graph describing known causal relationships between possible failed tests reported by the respective ones of the aircraft systems, and possible failure modes of the respective ones of the aircraft systems. The onboard reasoner diagnoses a failure mode of the aircraft system or another of the aircraft systems, from the failed tests, and using a graph-theoretic algorithm and the onboard diagnostic causal model. A maintenance action is determined for the failure mode, and a maintenance message is generated including the maintenance action.
提供了一种用于诊断飞机上的故障的方法和系统,该飞机包括被配置为向机载推理机报告故障的飞机系统。该方法包括在飞机的机载计算机处从飞机系统中的一个飞机系统接收故障报告,该故障报告指示由飞机系统报告的失败测试。机载推理机访问机载诊断因果模型,该机载诊断因果模型由描述由飞机系统中的相应飞机系统报告的可能的失败测试与飞机系统中的相应飞机系统的可能的故障模式之间的已知因果关系的图表表示。机载推理机根据失败测试并且使用图论算法和机载诊断因果模型来诊断飞机系统中的一个飞机系统或另一飞机系统的故障模式。确定用于故障模式的维护动作,并且生成包括维护动作的维护消息。
