Abstract

The invention discloses an arc burning recognition method based on improved AlexNet, comprising the following steps: S1. Establishing a convolutional neural network and obtaining a training model; S2. Obtaining an image; S3. Inputting the obtained image into the training model for image recognition; The convolutional neural network is an improved AlexNet network. The structure of the improved AlexNet network is an input layer, multiple sequentially connected convolutional layers, a fully connected layer, and an output layer; the convolutional layer connected to the input layer adopts M×M Convolution kernel architecture, and the remaining convolution layers use 1×M and M×1 convolution kernel architectures; the present invention uses 1×M and M×1 size convolution kernels in series to replace the M×M size volume in the original AlexNet network The accumulation kernel greatly reduces the number of parameters, and adds a non-linear layer to make the network structure deeper; simplifies the model, greatly shortens the training time, improves the training efficiency, and the recognition accuracy is higher than the original AlexNet network.

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 arc of the railway catenary is caused by the galloping of the catenary, the bouncing of the pantograph, and the ionization of the air into a conductor due to the voltage exceeding the endurance of the air. Intermittent, causing abnormal deceleration and acceleration during train operation, increasing the discomfort during the journey. Through the arc alarm, the faulty contact line or pantograph can be repaired in time, reducing the risk of railway power supply safety accidents. occurs; after the arc alarm is transmitted back to the data terminal, it needs to be confirmed by manual interpretation. If the false alarm rate is too high, it will cost a lot of labor costs, and if the false alarm rate is too high, it will increase the probability of accidents. Therefore, , Effectively identifying the...
