Problems solved by technology

[0003] The existing galloping monitoring method is mainly to install sensors on the wires to detect the galloping of the wires in real time, but this method will bring additional burdens and safety hazards to the wires, and the power supply of the sensor equipment is also difficult to solve; image recognition-based The galloping detection method is mainly to directly detect the edge of the wire, extract the wire in the image, and calculate the galloping amplitude, but it is difficult to extract the edge of the wire in complex environments, such as night, fog, rain and snow, and image recognition usually will fail, resulting in undetectable wire gallop results

Embodiment Construction

[0061] In this example, if Figure 5 As shown, a wire galloping monitoring method based on marker image detection includes the following steps:

[0062] Step 1. Install the markers on the spacer rods of the transmission line conductors. It is recommended to install them on the spacer rods closest to the sag point of the conductors; the markers are black or black and white geometric patterns, mostly with regular structures, clear outlines, and easy Recognized morphological objects, such as figure 1 circular as shown, such as figure 2 The triangle shown, such as image 3 The concentric circles shown, such as Figure 4 The concentric triangles shown, etc.;

[0063] Step 2. Set up a camera on the power tower or tower base to take pictures of the landmarks, so as to obtain the video data of the landmarks;

[0064] Step 3, performing image processing on the video data of the marker, identifying the marker, and calculating the center coordinates of the marker;

[0065] Step 3....

Abstract

The invention discloses a wire galloping monitoring method based on marker image detection, the steps of which are to install markers with regular structure, clear contours and easy identification on spacers of power transmission wires; Set up a camera to take pictures of the landmarks, identify the landmarks through image processing algorithms, and calculate their center coordinates, so as to obtain the trajectory of the landmarks and achieve the effect of real-time monitoring of wire galloping.

Description

technical field [0001] The invention belongs to the technical field of power transmission line state monitoring, in particular to a wire galloping monitoring method based on marker image recognition. Background technique [0002] Conductor galloping in transmission lines refers to the low-frequency, large-amplitude self-excited vibration phenomenon of overhead conductors with uneven ice coating under the action of strong winds. Conductor galloping has been an important factor affecting the safety of power grid transmission lines for a long time. It will cause tripping of transmission lines, part of the bolts falling off the cross-arm of the iron tower, and damage to the cross-arm of the iron tower, jumpers, insulators, and hardware, which will make the operation of the power grid face severe challenges. [0003] The existing galloping monitoring method is mainly to install sensors on the wires to detect the galloping of the wires in real time, but this method will bring addi...
