A method for online detection and recognition of anti-vibration hammer faults based on binocular vision images

Abstract

The invention discloses an on-line detection and recognition method for anti-vibration hammer faults based on binocular vision images, comprising the following steps: adopting two cameras to form a binocular stereo vision system; establishing an anti-vibration hammer state attribute set S; , obtain the initial image information with the anti-vibration hammer and fixed reference object, and obtain the initial value S of the anti-vibration hammer state attribute set S by obtaining the three-dimensional coordinates of the anti-vibration hammer and the three-dimensional coordinates of the fixed reference object through the initial image information 0 ; In the current state, when it is found that the anti-vibration hammer has an abnormal fault, the current image information with the anti-vibration hammer and the fixed reference object is obtained, and the three-dimensional coordinates of the anti-vibration hammer and the fixed reference object are obtained through the current image information to obtain the anti-vibration hammer. The current value S of the hammer state attribute set S t ;Identification of anti-vibration hammer fault type: according to the current value S t with initial value S 0 Calculate the change value △S of the state attribute of the anti-vibration hammer, and judge the failure of the anti-vibration hammer according to △S.

Description

technical field [0001] The invention relates to the detection technology of an anti-vibration hammer, in particular to an on-line detection and recognition method for an anti-vibration hammer fault based on a binocular vision image. Background technique [0002] The overhead transmission line is affected by meteorological conditions such as wind, ice, and low temperature, causing the line to vibrate and gallop. If the vibration frequency is high and the amplitude is small, the wind vibration will cause the overhead wire to be bent repeatedly at the suspension point, which will cause material fatigue. If the frequency of galloping is very low, but the amplitude is large, it is easy to cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burnt wires. [0003] The anti-vibration hammer is an indispensable part in the safety measures of overhead transmission lines. It is one of the important anti-vibration fittings. The large vi...

Problems solved by technology

However, in reality, anti-vibration hammers often have faults such as displacement faults, damage faults, shedding faults, foreign object interference, etc. These faults will threaten the life of transmission lines and the safety of transmission corridors
