5G technology facilitates the implementation of smart grids. In order to solve the prominent contradiction between the heavy workload of power transmission line inspection and low manual operation efficiency, the Shenzhen Power Supply Bureau explored the application of 5G, artificial intelligence and other technologies, deployed 2727 sets of smart cameras on the transmission line, and created a new generation of intelligent power transmission inspection system , The staff can “see the Pengcheng Tower in one day” without leaving home, and the inspection efficiency is 11 times higher than that of manual operation. The inspection robot starts to work instantly and freely, which greatly improves the work efficiency and safety level.
