Pump equipment operation fault diagnosis method and device based on small samples

The invention discloses a machine and pump equipment operation fault diagnosis method and device based on a small sample. The method comprises the following steps: collecting small sample data of machine and pump equipment operation; preprocessing the small sample data of the operation of the pump equipment; constructing and training a teacher model; constructing a student model, and performing supervision training on the student model through the trained teacher model according to a knowledge distillation method; and inputting the preprocessed small sample data into the trained student model so as to carry out fault diagnosis on the pump equipment. According to the invention, on the basis of the small sample data, the teacher model is constructed to supervise and train the student model, and high-accuracy machine pump equipment fault diagnosis can be realized. 本公开揭示了一种基于小样本的机泵设备运行故障诊断方法及装置，其方法包括：采集机泵设备运行的小样本数据；对机泵设备运行的小样本数据预处理；构建并训练教师模型；构建学生模型，根据知识蒸馏法通过训练好的教师模型对学生模型进行监督训练；将预处理后的小样本数据输入训练好的学生模型中，以对机泵设备进行故障诊断。
