AI Technical Summary

Technical Problem

Existing technologies for detecting corrosion on power transmission towers suffer from problems such as difficulty in balancing accuracy and efficiency, rigid allocation of computing resources, and lack of adaptive sensing capabilities, resulting in low detection efficiency, high costs, and safety risks.

Method used

A collaborative diagnostic system for transmission tower corrosion based on low-altitude IoT is adopted, including mobile edge nodes and a cloud diagnostic platform. The system uses an initial corrosion detection model for preliminary analysis, combines false positive filtering rules based on geometric dimensions and risk weighting rules based on regional importance, outputs images of salient regions, and transmits them to the cloud diagnostic platform through a low-power communication module for high-precision corrosion segmentation and quantitative analysis.

Benefits of technology

It achieves both real-time and high-precision corrosion detection under limited edge computing power, dynamically optimizes the allocation of computing resources, improves the targeting and engineering practicality of the detection, provides a basis for priority decision-making, and reduces system latency and resource waste.
