Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The present invention takes four split wires as an example.

[0037] A monitoring method for wire galloping based on spacer rod identification of the present invention is specifically implemented according to the following steps, and the flow chart is as follows figure 1 Shown:

[0038] Step 1. Collect the video image signal of the transmission line through the PTZ camera installed on the transmission tower, and then transmit it back to the monitoring center in real time in the form of video stream through the 3G transmission channel. The on-site image is as follows: figure 2 shown;

[0039] Step 2, in the monitoring center, intercept the digital image transmitted from the video stream in the step 1 in real time to obtain the target image;

[0040] Step 3, preprocessing the target image obtained in step 2 to obtain a high-quality i...

Abstract

The invention discloses a wire galloping monitoring method based on spacer rod identification, which takes digital images intercepted from video streams of power transmission lines as research objects, and preprocesses the images by means of image grayscale, smoothing and denoising. Threshold segmentation, edge detection, contour tracking and compensation are performed on the preprocessed image, the contour of the wire spacer is extracted, and the dancing torsion angle is calculated according to the contour matching difference shape of the spacer template before and after dancing. When the dancing torsion angle is abnormal, the early warning information can be sent to the safety inspectors in time, so that they can pay attention to the operation status of the line and take corresponding measures. The wire galloping monitoring method based on spacer identification of the present invention does not need to establish an accurate mathematical model, and can quickly and automatically realize the detection and early warning of the wire galloping torsion angle.

Description

technical field [0001] The invention belongs to the technical field of machine vision and on-line monitoring of power transmission lines, and in particular relates to a monitoring method for galloping of wires based on spacer identification. Background technique [0002] The galloping phenomenon of the transmission line often occurs when it is affected by itself and the external environment, especially in severe weather and other conditions, which will cause abnormal galloping of the transmission wire. Long-term large-scale swings of conductors can easily cause phase-to-phase flashover, resulting in damage to fittings and insulators, line tripping, broken strands or disconnected wires, and even major accidents such as damage to the transmission grid caused by pulling down poles and towers. Therefore, realizing real-time monitoring of conductor galloping and accurate and rapid identification of abnormal conductor galloping are the keys to preventing and timely controlling con...
