Problems solved by technology

However, because it is exposed outside for a long time, it is damaged by rain, sunshine, ice and snow, temperature difference and other natural environments all the year round, and it is prone to cracks and other damages, and because these cracks are very small, they are not easy to be found. Therefore, the safety of transmission lines operation constitutes a potential hazard
At present, the common detection method for transmission tower cracks is mainly to carry out manual inspection of the transmission tower with the help of a telescope, but this method is not only inefficient, but also expensive and dangerous, which is not conducive to effective deployment on a large scale.
[0003] At present, in the existing technology, there is no efficient and reasonable method for detecting new cracks in transmission towers

Embodiment 1

[0047] Embodiment 1: Step1: Establish the transmission tower information database; All transmission towers in area A are uniformly coded and marked (j=1,2,3,...), and to the position information of the transmission iron tower of all coding identifications, the registration record of supervisory information, adopt MySQL database software to set up the information database of transmission iron tower;

[0048] The location information includes: longitude, latitude and altitude; the supervision information includes: supervision unit, supervisor and contact information;

[0049]Step2: Original crack sample image collection; use a digital camera to collect crack images of transmission towers to collect all crack images of transmission towers in the area, register and record the position of each crack image on the tower and the information of the code identification of the tower, and then The crack image is stored in the data center, and the MySQL database software is used to establ...

Embodiment 2

[0090] Embodiment 2: It is known that there are 10 transmission towers in area A, and there are 50 original crack sample images;

[0091] First, code and identify the 10 transmission towers in A in the area [A 1 ,A 2 ,A 3 ,...,A 10 ]; registration record A 1 ~A 10 For the location information and supervision information of the transmission tower, the MySQL database software is used to establish the transmission tower information database;

[0092] Secondly, register and record the position of each original crack image on the iron tower and the information of the code identification of the iron tower, and store it in the data center; use MySQL database software to establish the original crack sample image database; based on the Matlab software platform, the original crack image is processed processing; and set up a crack analysis model according to the results of image processing, after cluster analysis by adopting K-means algorithm, obtain: V=[V 1 ,V 2 ,V 3 ,V 4 ];

Abstract

The invention relates to a crack detecting method and particularly relates to a method of detecting newly increased cracks of power transmission towers in an area. The method includes a first step of subjecting all the power transmission towers in the area to unified coding identification and establishing a power transmission tower information database, a second step of collecting original crack images, processing the original crack sample images, and building a crack analysis model according to image processing results, a third step of collecting non-original crack zone images and processing the non-original crack zone images, and a fourth step of identifying and determining the newly increased cracks, namely a step of identifying and determining cracks in the collected non-original crack zone images according to the crack analysis model, and transmitting crack information of power transmission towers with the identified and determined newly increased cracks to a monitoring terminal. The method reduces the labor cost, greatly increases detection precision of the newly increased cracks of the power transmission towers, increases the working efficiency, and effectively eliminates potential safety hazards in the power transmission towers.

Description

technical field [0001] The invention relates to a method for detecting cracks, in particular to a method for detecting new cracks in transmission towers in an area. Background technique [0002] As an important part of basic power facilities, transmission towers are of great significance to their safe operation. However, because it is exposed outside for a long time, it is damaged and eroded by rain, sunshine, ice and snow, temperature difference and other natural environments all the year round, and it is prone to cracks and other damages, and because these cracks are very small, it is not easy to be found. Therefore, the safety of transmission lines operation constitutes a potential hazard. At present, the common method of detecting cracks in transmission towers is mainly to carry out manual inspections of transmission towers with the help of telescopes carried out by helicopters. However, this method is not only inefficient, but also expensive and dangerous, and is not c...
