Problems solved by technology

[0003] If the existing wire monitoring method book is to install sensors on the wires, this method will bring additional burden and safety hazards to the wires, and the power supply of the sensor equipment is also difficult to solve; the detection method based on the camera and image processing technology is Qualitative monitoring of galloping and quantitative monitoring need to further improve the accuracy of image processing; although the monitoring device based on the acceleration sensor can realize quantitative detection of galloping in the transmission line, when the wire is twisted instead of galloping, the acceleration sensor is still There will be measurement results output, and the wire galloping calculated by using this data will inevitably deviate, which will affect the measurement accuracy

Embodiment Construction

[0064] In this example, if image 3 As shown, an online monitoring method for wire galloping based on rectangular image detection is to install a rectangular marker at the sag point of the wire and identify the center point of the rectangular structure to obtain the galloping track of the wire. The marker is a black rectangular pattern with regular structure, and An infrared night vision camera is set up on the tower to shoot the landmarks, obtain video data, process the video data, obtain the center coordinates of the geometric pattern, and then obtain information such as the trajectory of the wire dancing, the amplitude of the wire dancing, etc., so that the transmission wire is always in the Within the scope of monitoring, an alarm value is set. Once there is an abnormal situation in the wire galloping, corresponding measures are taken to absorb the vibration energy of the wire and reduce the vibration intensity. Specifically, the following steps are included:

Abstract

The invention discloses a conductor galloping on-line monitoring method and device based on rectangular image detection, and the method comprises the steps: installing a rectangular marker at a conductor sag point, erecting an infrared night vision camera on a tower, shooting the marker, obtaining video data, processing the video data, so that center coordinates of the rectangular marker are obtained, and then the information such as the conductor galloping track and the maximum amplitude of conductor galloping is obtained. According to the invention, conductor galloping can be monitored in real time, and the conductor galloping identification rate and detection precision are improved.

Description

technical field [0001] The invention belongs to the technical field of state monitoring of overhead wires, in particular to an online monitoring method and device for wire galloping based on rectangular image detection. Background technique [0002] When the lightning conductor is subjected to wind force in the breeze, the leeward side of the conductor will generate a vortex-like wind rotation, and the vortex-like wind rotation will cause the conductor to be under the vertical pressure of the upper line. Under the action of this pressure, the entire span of the conductor lightning conductor will be It produces periodic oscillations in the vertical direction up and down, and its existence seriously affects the operation safety of the entire overhead transmission line, and may even cause power transmission to be interrupted. During its operation, affected by the wind force, the wire structure of the line vibrates vertically, and then vibration problems arise. This periodic os...
