Description

Technical Field

[0001] The present invention belongs to the technical field of power transmission line inspection, and in particular relates to a power transmission line inspection system based on multi-source data. Background Art

[0002] With the implementation of the power transmission network construction project, the number of transmission lines has increased dramatically, and the workload of line maintenance has increased dramatically. Due to the complex geographical environment and changeable climatic conditions, traditional manual inspection operations cannot achieve comprehensive inspections of power lines. There may be negligence and omissions in the inspection of some equipment. It is difficult to manually check the lines in mountainous areas with complex geographical environments, and blind spots in power line inspections are prone to occur. The inspection efficiency and accuracy are low, and the labor intensity is high.

The image data fusion module analyzes, processes and fuses visible light images and video data, infrared thermal image data and ultraviolet imaging image data. The noise recognition module detects and recognizes the equipment operation sound. From the various noise reverberations in the on-site environment, the sound belonging to the equipment operation is picked out to jointly form multi-source information data of the transmission line corridor facilities and equipment. The fault analysis and prediction unit analyzes and processes the multi-source image and noise data processed by the data processing unit and the collected meteorological data based on a deep learning algorithm, determines the power transmission facility equipment target, screens the fault warning feature items, and predicts and judges the possible critical faults of the power transmission line by comparing the features with the power transmission facility equipment fault library and the fault analogy library, and issues an alarm through the inspection alarm unit; The transmission line visualization unit displays images of transmission equipment, transmission line infrastructure and surrounding facilities, as well as drone inspection paths and results, drone monitoring images, fault feature analysis, and unified display of fault causes, fault locations and diagnosis results.
