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 method for monitoring conductor galloping based on spacer recognition. The monitoring method takes a digital image intercepted in a video stream of a power transmission line as a research object, and the image is pre-processed through an image graying method, a smooth de-noising method and the like. The pre-processed image is subjected to threshold segmentation, edge detection, and outline tracking and compensation; the outline of a conductor spacer is extracted; and a galloping torsion angle is calculated according to the outline matching difference shape of a spacer template before and after galloping. When the galloping torsion angle is abnormal, early warning information can be sent to a safety inspector in time, so that a line operation condition is concerned and corresponding processing measures are adopted. According to the method for monitoring the conductor galloping based on the spacer identification, an accurate mathematic model does not need to be established, and the detection and early warning of the galloping torsion angle can be rapidly and automatically realized.

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...
