Abstract

The invention discloses an improved AlexNet-based burning arc identification method. The method comprises the following steps of S1, building a convolutional neural network and obtaining a training model; S2, obtaining an image; and S3, inputting the obtained image to the training model for performing image identification, wherein the convolutional neural network is improved AlexNet, the structureof the improved AlexNet sequentially comprises an input layer, multiple convolutional layers connected in sequence, a full connection layer and an output layer, the convolutional layers connected with the input layer adopt MXM convolutional kernel architectures, and the test of the convolutional layers adopt 1XM and MX1 convolutional kernel architectures. According to the method, MXM convolutional kernels in original AlexNet are replaced with 1XM and MX1 convolutional kernels connected in series, so that a parameter quantity is greatly reduced; a nonlinear layer is added, so that the networkstructure is deeper; and the model is simplified, so that the training time is greatly shortened, the training efficiency is improved, and the identification accuracy is higher than that of the original AlexNet.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to an arc recognition method based on improved AlexNet. Background technique [0002] The arcing of the railway catenary is due to the dancing of the catenary, the bouncing of the pantograph, and the voltage exceeding the tolerance of the air, which makes the air ionized and becomes a conductor and then generates an arc; arcing will cause the operation of the electric locomotive to be unstable, so that the electric locomotive will Intermittent, causing abnormal deceleration and acceleration during the train operation, increasing the discomfort during the journey, through the arcing alarm, the faulty contact wire or pantograph can be repaired in time, reducing the risk of railway power supply safety accidents occurrence; the arcing alarm needs to be confirmed by manual interpretation after it is transmitted back to the data terminal. , effectively identifying the arc can greatly red...
