The invention discloses a fault diagnosis reasoning method based on a discriminant vector and an incidence matrix, and belongs to the technical field of aircraft fault diagnosis. Comprising the following steps: establishing a fault incidence matrix between a fault mode and a measuring point; constructing a fault discrimination vector according to the fault incidence matrix measuring point type, and counting the sum of elements of each row vector of the fault incidence matrix to form an element counting vector; and forming a fault reasoning model by using the fault discrimination vector and the fault incidence matrix, comparing the fault reasoning model with an element counting vector, and finally realizing fault diagnosis based on the discrimination vector and the incidence matrix. According to the method, the detailed process of reasoning is given, and the universal fault diagnosis method is further improved.

    本发明公开了一种基于判别向量与关联矩阵的故障诊断推理方法,属于飞机故障诊断技术领域。包括以下步骤:建立故障模式与测点之间的故障关联矩阵;根据故障关联矩阵测点类型构造故障判别向量,统计故障关联矩阵各行向量的元素之和,构成元素计数向量;利用故障判别向量和故障关联矩阵形成故障推理模型,与元素计数向量进行比较,最终实现基于判别向量与关联矩阵的故障诊断。本发明给出了推理的详细过程,进一步完善了通用的故障诊断方法。
