Embodiment approach

[0046] As a preferred implementation, the monitoring image defect identification method further includes an incremental learning step, performing incremental learning during the classification and judgment process, and continuously optimizing the classification surface. Store the support vectors obtained in the initial training of the feature vector library (in the process of SVM classification and judgment, the feature vectors that meet the KKT condition constraints, that is, the feature vectors that meet the Y(i)*f(Xi)>=1 condition are support vectors, Y (i) indicates the category to which the sample belongs, f(Xi) indicates the classification surface function) to form a feature library; after the monitoring picture is input into the SVM classifier for classification and judgment, manually identify whether the classification result is correct, and if the classification is correct, proceed to the next monitoring classification of images. If the classification is wrong, it is ...

Abstract

The invention belongs to the technical field of remote monitoring, and discloses a remote intelligent line inspection method for power transmission lines. First, an image acquisition device is started to obtain monitoring pictures of the power transmission line and monitoring pictures of the surrounding environment of the power transmission line; and then the monitoring pictures are passed through the communication system. It is transmitted to the monitoring background; the monitoring background receives and analyzes the monitoring pictures, and judges whether the acquired monitoring pictures have defects, that is, judges whether the transmission lines displayed in the monitoring pictures are faulty, and sends an alarm message if there are defects in the monitoring pictures. The remote intelligent line inspection method for transmission lines of the present invention can carry out real-time online inspection of transmission lines, and the inspection cycle is short, which avoids the problems of manual line inspection such as difficulty and long cycle, and also avoids the problem of high cost of helicopter line inspection, and also solves the problem It solves the temporary and random problems existing in the existing transmission line monitoring methods.

Description

technical field [0001] The invention relates to the technical field of remote monitoring, in particular to a remote intelligent line inspection method for power transmission lines. Background technique [0002] In recent years, with the development and improvement of the grid structure, the construction of high-voltage and ultra-high-voltage transmission lines has developed rapidly. Due to the particularity of the geographical location and environmental conditions of the transmission line, it is exposed to the wild all year round, and is subject to natural weather such as wind, rain, fog, snow, hail, lightning, and natural disasters such as floods, earthquakes, landslides, and debris flows. It is also threatened by human factors such as rock mining, construction blasting, theft and destruction, and the safe operation of transmission lines is seriously threatened. Regular or irregular monitoring of the operation status of the transmission line (that is, monitoring whether th...
