Traffic Infrastructure: "Aerial Inspection" Solves Operation and Maintenance Difficulties

In China's more than 190,000 kilometers of expressway network, unmanned aerial vehicles (UAVs) have become the "clairvoyant eyes" of operation and maintenance personnel. Yunnan Communications Investment and Construction Group has adopted a formation mode of "2 snow-melting agent spreading UAVs + 1 emergency warning UAV", which can complete snow-melting operations on complex interchanges in 1.5 hours. Compared with traditional vehicles, the efficiency is increased by 40%, and the usage of snow-melting agent is reduced by 30%.
For track inspection of Shenzhen Metro, UAVs can penetrate darkness and dust, clearly capture details such as loose track bolts and worn catenary, and avoid potential safety risks of manual inspection.

In the fields of bridge and water conservancy projects, the advantages of UAVs are even more prominent. The "aerial doctors" of Aizhai Bridge can operate stably in extreme weather and accurately identify concrete cracks. Modeling a 5-kilometer river channel only takes 4 days, which is 20 times faster than traditional methods, providing high-precision data support for water conservancy planning.
DJI's newly released Matrice 4 series UAVs are equipped with 48-megapixel telephoto cameras, which can clearly see license plates 250 meters away and pin cracks 10 meters away, upgrading infrastructure inspection from "manual climbing" to "intelligent overlooking".
