Description

Technical Field

[0002] The materials of the collection lines of wind and solar power stations include wires, joints, hangers, insulators and other components. During the inspection process, it is necessary to observe the wear of these components, whether there is oxidation, deformation and other phenomena, as well as to check the corridor environment of the line, and use the detection equipment to perform necessary tests, such as zero value detection of insulators, etc., especially when the wind is strong, it is easier to cause wear and damage to these components, and they need to be replaced or repaired in time. Once problems or defects are found in the line, the inspectors will immediately record them and take corresponding measures. For some urgent problems, they will be reported immediately and arranged for professionals to deal with them. For general problems or defects, they will be included in the maintenance plan and repaired or replaced at the appropriate time. After the inspection, the inspectors will also submit a detailed inspection report for subsequent reference and analysis. The following problems exist in the existing technology:

[0003] Because the inspection of the collector lines of existing wind and solar power stations mainly relies on manual inspection methods, when there are many inspection contents, the efficiency of manual inspection is slow and it is easy to miss problems. At the same time, when inspections are carried out in bad weather, there are certain safety hazards. At the same time, when problems are found during the inspection, they can only be collected through manual records, and the data collection speed is also slow, which affects the maintenance efficiency.
