Power fittings in power transmission and distribution lines that are intact are often distinguished from power fittings that have thermal defects by extrinsic features, which may include color features and shape features. For example, an electric power fitting with a thermal defect may melt at a high temperature, when the material of the electric power fitting includes aluminum, the electric power fitting may melt molten aluminum even at the high temperature, and the local color of the electric power fitting in this state is approximately white, so that whether the electric power fitting has the thermal defect may be determined according to the material and color characteristics of the electric power fitting by using an image processing technology. For example, the hardware may be fused at a high temperature, so that the shape of the hardware is incomplete, or a wire connected to the hardware is broken, and therefore, whether the hardware has a thermal defect may be determined according to the shape characteristics of the hardware by using an image processing technology.

Illustratively, the routing inspection image is renamed according to the shooting position of the power transmission and distribution line, namely the routing inspection image is renamed according to the line name, the pole tower number and the routing inspection position, so that the routing inspection image name comprises information of the specific line, the pole tower and the routing inspection position.
And S230, screening the routing inspection image containing the electric power fitting according to the shot part.
For example, images of towers, lines, electric power fittings and the like in the power transmission and distribution line can be stored in advance, all routing inspection images are screened according to priori knowledge through machine learning, and the images of key parts including the power transmission and distribution line in the routing inspection images, such as the images including the electric power fittings, are screened out.
Optionally, the tower in the power transmission and distribution line comprises a tension tower, the electric power fitting comprises a splicing fitting, and the shooting part comprises a position on the side of the tension tower; correspondingly, step S230 may specifically include: and screening the routing inspection images of the continuous hardware fittings of all parts including the lines and/or the strain towers according to the position of the number side. Specifically, when the shooting position of patrolling and examining the image includes the large-size side and the small-size side of strain insulator tower, the large-size side of strain insulator tower generally is provided with the gold utensil such as strain insulator clamp, consequently can sieve out this image of patrolling and examining.

Optionally, the performing feature recognition on the image information of the electric power fitting to determine whether the electric power fitting has a thermal defect includes: and comparing the original image and the inspection image of the electric power fitting to determine whether the electric power fitting has the thermal defect. Specifically, intact power fittings and power fittings with thermal defects have different shape characteristics, for example, connection fittings such as a drainage plate can be fused at high temperature to cause incomplete shapes, and connection fittings such as a parallel groove clamp can be fused at high temperature to cause shape differences with images of normal parallel groove clamp connection wires. Therefore, the original image of the electric power fitting can be stored in advance, then the original image and the screened inspection image are compared based on the image processing technology, and whether the electric power fitting has the thermal defect or not is determined according to the matching degree of the original image and the inspection image. For example, a matching degree value may be preset, for example, the matching degree value is 98%, the original image and the inspection image of the power fitting are compared, when the matching degree of the original image and the inspection image is greater than or equal to 98%, it is determined that the power fitting has no thermal defect, and when the matching degree of the original image and the inspection image is less than 98%, it is determined that the power fitting has a thermal defect. This scheme confirms whether electric power fitting has the thermal defect according to electric power fitting's original image and the matching degree of patrolling and examining the image, is favorable to promoting the accuracy of thermal defect discernment, compares with artifical discernment's mode, is favorable to promoting the work efficiency of thermal defect discernment.
On the basis of the above scheme, optionally, the method for identifying a thermal defect further includes: and if the electric power fitting has thermal defects, alarming according to the shooting part of the electric power fitting. Specifically, the shooting part to which the power fitting belongs includes towers and lines in the power transmission and distribution line, if the power fitting has a thermal defect, an alarm is given according to the shooting part to which the power fitting belongs, and the alarm can be given according to whether the power fitting in each tower and each line has the thermal defect. For example, when the electric power fitting in a certain tower has a thermal defect, an alarm is given, and the alarm information includes the number of the tower. The advantage that sets up like this lies in, can in time inform through reporting to the police that patrol and examine the staff and go to the scene and carry out the secondary and confirm, dwindle the screening scope of hot defect problem for the staff.
