Abstract

The invention relates to the technical field of power cables, and discloses a method and system for quickly checking the white head of a secondary cable, and the method comprises the steps: carrying out gray processing and binarization processing on a cable white head image to obtain a binary image; constructing an initial numerical value matrix according to the gray value of the binary image; extracting a plurality of contour character features and a corresponding position relation thereof; performing character segmentation on each contour character feature to generate a character matrix; matching the character matrix to obtain a corresponding binary template image; identifying the binary template image to obtain corresponding numerical data; performing the position arrangement on the numerical data according to the numerical data and the position relation thereof so as to obtain cable white head numbers; and checking the reference cable white head numbers and the cable white head numbers to obtain a checking result. Thus, the checking efficiency and accuracy are improved.

Description

technical field [0001] The present invention relates to the technical field of power cables, in particular to a method and system for quickly checking white ends of secondary cables. Background technique [0002] With the continuous development of China's power grid, the continuous improvement of the power grid structure, and the continuous update and progress of power grid technology, the continuous increase in substations, power grid equipment, and secondary circuits has also led to work. The workload has increased sharply, but the staff often cannot keep up with the increase in workload due to various reasons, resulting in the overwhelmed team members at the grassroots level, unable to take into account the details of project acceptance, resulting in frequent errors and accidents. In this huge workload, the acceptance work and daily maintenance of the secondary circuit are the most important. There are many and complicated secondary lines, and there are many details for a...
