Abstract

The invention provides a transformer substation insulator infrared image detection method based on artificial intelligence. The transformer substation insulator infrared image detection method comprises the following steps: acquiring an infrared image of a transformer substation insulator through an infrared thermal imager; preprocessing the acquired image through an algorithm; performing target label processing on the obtained data set; dividing the data set into a training set and a test set; constructing an infrared image detection model of the improved feature fusion single-shot multi-boxdetector; carrying out training and parameter adjustment of the model by using a training set in the data set; performing target detection on the trained model by using a test set in the data set so as to prove the effectiveness of the model; through the above steps, automatic detection of the infrared image of the transformer substation insulator is achieved. By adjusting the parameters of the model and adding a feature enhancement module, the feature extraction capability of the model for the insulator is improved, and therefore it is ensured that safe and real-time detection is conducted onthe infrared image of the transformer substation insulator.

Description

technical field [0001] The invention relates to the field of safety monitoring of the operating state of electric equipment, in particular to an artificial intelligence-based infrared image detection method for substation insulators. Background technique [0002] With the continuous growth of China's electricity demand and the continuous expansion of the scale of the power system, the safety and stability of substations in the power system are becoming more and more important. Insulators are one of the most common electrical equipment in power systems. They are widely used in the insulation of conductors in power systems and the mechanical support of electrical equipment. Therefore, insulators are one of the key factors affecting the normal operation of substations. Most of the insulators are installed in the natural environment. Due to long-term exposure to the natural environment, various failures will occur to the insulators. The failure of insulators will seriously thre...
