However, in practical applications, a large number of clips with different characteristics, such as appearance and texture, are difficult to collect at one time. Then there are clips with new features. The current solution is to combine the collected data with the previous ones. The collected data is unified and retrained. This solution has a flaw. With the addition of newly collected data, the overall data becomes more and more, the model training becomes slower and slower, and the model update cycle becomes longer and longer. , seriously affecting work efficiency

Embodiment 1
[0047] like figure 1 As shown in the figure, it is a flow chart of a method for automatic detection and defect identification of power grid clamps proposed by the present invention.
[0048] refer to figure 1 , a method for automatic detection and defect identification of wire clips in a power grid, comprising the following steps:
[0049] Step 101, obtain the wire clip picture through the image acquisition module;
[0050] Step 102, train the wire clip picture to obtain the wire clip type;
[0051] Step 103, classify and delete the clip pictures;
[0052] Step 104, identifying and outputting the fault line clamp.
[0053] In the embodiment of the present invention, the image acquisition module is used to collect images of the clamps on the transmission line, and the Faster R-CNN technology is used to train the pictures of the clamps to obtain the type of clamps and realize the classification of the types of clamps. The training and identification of the fault line clips ...
Embodiment 2
[0078] Based on the same inventive concept as the method for automatic detection and defect identification of power grid clamps in the foregoing embodiments, the present invention also provides an automatic detection and defect identification device for power grid clamps.
[0079] see Figure 5 , an automatic detection and defect identification device for grid wire clips, comprising:
[0080] Image collection module 201, used to obtain the wire clip picture;
[0081] Wire clip type training module 202, for training the wire clip picture to obtain the wire clip type;
[0082] The wire clip classification module 203 is used to classify and delete the wire clip pictures;
[0083] The clamp fault detection module 204 is configured to identify and output faulty clamps.

Abstract
The invention discloses an automatic detection and defect identification method for a power grid wire clamp. The method comprises the following steps: acquiring a wire clamp picture through an image acquisition module; training the wire clamp picture to obtain a wire clamp type; classifying, deleting and selecting the wire clamp pictures; and identifying and outputting the fault wire clamp. The invention also discloses an automatic detection and defect identification device for the power grid wire clamp. According to the method and the device, image acquisition is carried out on the wire clampon the power transmission line through the image acquisition module; the Faster R-CNN technology is adopted to train the wire clamp pictures, the augmented training technology is adopted, the defectsthat the time is long and the model updating period is slow due to the fact that new wire clamp features need to be retrained are overcome, fault detection is conducted on the wire clamp, the maintenance cost is greatly saved, and a line patrol system is more efficient and intelligent.
Description
technical field [0001] The invention relates to the technical field of safety of overhead power transmission lines, in particular to a method and device for automatic detection and defect identification of power grid clamps. Background technique [0002] In the overhead transmission line, various transmission lines are intertwined, and the transmission lines may be entangled, pulled, and vibrated with each other, which can easily lead to strand breakage and seriously threaten the safe and reliable operation of the overhead transmission line. As an important device in overhead transmission lines, wire clips can wrap a large number of transmission lines, protect the transmission lines and assist vibration reduction, and greatly extend the service life of the transmission lines. However, overhead transmission lines are used for long-distance power transmission, and they must cross different natural environments during the period. After a long period of exposure to wind and sun...
