As the industry gradually enters the stage of unmanned and intelligent, factories in the future need to realize intelligent monitoring and diagnosis and maintenance of parts and components. In order to achieve this goal, it is first necessary to accurately identify and classify the parts in the factory. However, the existing literature rarely studies the classification and identification of parts of the entire factory. Due to the lack of existing data samples, this paper studies the identification and classification of small samples of industrial machine parts. In order to solve this problem, this paper establishes a convolutional neural network model based on the InceptionNet-V3 pretrained model through migration learning. Through experimental design, the influence of data expansion, learning rate and optimizer algorithm on the model effectiveness is studied, and the optimal model was finally determined, and the test accuracy rate reaches 99.74%. By comparing with the accuracy of other classifiers, the experimental results prove that the convolutional neural network model based on transfer learning can effectively solve the problem of recognition and classification of industrial machine parts with small samples and the idea of transfer learning can also be further promoted.
随着行业逐渐进入无人化和智能化阶段,未来的工厂需要实现对零部件的智能监测和诊断与维护。要实现这一目标,首先需要对工厂中的零部件进行准确地识别与分类。然而,现有的文献很少研究整个工厂零部件的分类与识别。由于缺少现有数据样本,本文研究了工业机器零部件小样本的识别与分类。为了解决这个问题,本文通过迁移学习,基于 InceptionNet-V3 预训练模型建立了卷积神经网络模型。通过实验设计,研究了数据扩充、学习率和优化器算法对模型有效性的影响,最终确定了最优模型,测试准确率达到 99.74%。通过与其他分类器的准确率比较,实验结果证明了基于迁移学习的卷积神经网络模型能够有效解决工业机器零部件小样本的识别与分类问题,同时也进一步验证了迁移学习的思想。
