The fault diagnosis method comprises the following steps: acquiring a parameter signal of operation of target equipment; obtaining a parameter vector according to the parameter signal; establishing a mapping relationship between the fault type and the parameter vector; establishing a fault diagnosis model by taking the parameter vector as an input training sample and the fault type as an output training sample; and applying the fault diagnosis model to fault diagnosis of the target equipment. According to the fault diagnosis method, by establishing the corresponding relation between the fault type and the parameter vector, all possible fault points can be diagnosed according to the change of the parameter signal, the comprehensiveness of fault diagnosis is optimized, the fault type can be quickly determined, and the accuracy of fault diagnosis is improved. 一种故障诊断方法，包括以下步骤：获取目标设备运行的参数信号；根据所述参数信号获得参数向量；建立故障类型与所述参数向量的映射关系；以所述参数向量为输入训练样本，以所述故障类型为输出训练样本，建立故障诊断模型；将所述故障诊断模型应用于所述目标设备的故障诊断。上述故障诊断方法，通过建立故障类型与参数向量之间的对应关
