AI Technical Summary

Technical Problem

The existing drone inspection path planning method fails to effectively consider the difference in the height of power equipment in different areas of the substation, resulting in large electricity consumption and shortening of the air stagnation time during drones during high altitude inspection, affecting the inspection efficiency.

Method used

Using point cloud processing and image analysis technology, the substation is divided into multiple patrol areas, and the flight paths are planned separately to make the altitude of power equipment in each area as close as possible, thereby reducing the flight altitude and extending the drone's stagnation time.

Benefits of technology

Through area division and flight path optimization, the drone's stagnation time is improved, the number of battery replacements is reduced, the efficiency of substation patrols is improved, and the difficulty of flight path planning is reduced.
