On October 25, at the line inspection site of Luosulfur Industrial Park in Jiangjin District, employees of the Luosulfur Power Supply Station of State Grid Chongqing Jiangjin Power Supply Company were operating a white drone to intelligentize 10 kV power distribution lines. Conduct inspections to find potential safety hazards in line equipment.

"UAV intelligent inspection is to collect and form a three-dimensional model through laser point cloud, and then plan the route according to the generated model to realize automatic UAV inspection. And through the defect identification in Chongqing Electric Power UAV intelligent inspection system The task module assists the manual search for hidden defects in the photos, performs classification and labeling statistics, and solves the problems of low efficiency and low refinement of traditional manual inspections." The relevant person in charge of the State Grid Chongqing Jiangjin Power Supply Company introduced that in order to further improve the power supply reliability and improve work efficiency. Since last year, the company has accelerated the pace of digital transformation, actively promoted the application of new technologies and new equipment in the production, operation and maintenance of transmission and distribution networks, vigorously promoted intelligent drone inspections, and deepened intelligent image recognition technology , improve operation and maintenance intelligent management and control capabilities, gradually realize the digital transformation and intelligent upgrade of drone inspections, and promote the transformation of new models of power transmission and distribution equipment management.

In 2023, Jiangjin Power Supply Company will focus on drone application as the team's core capability improvement focus, train 31 drone "pilots", configure 23 drones of various types, and establish a drone smart inspection system Management platform, operation and maintenance teams achieve full coverage of drone inspections. From January to October, a total of 738.72 kilometers of power transmission and distribution lines were inspected by drones, 44 refined inspection lines were inspected, and 117 defects and hidden dangers of various types were discovered. Intelligent drone inspections are used in the company’s power grid production and operation maintenance. Its role has become increasingly prominent, greatly improving the efficiency and intelligence level of operation and maintenance work.

In the next step, State Grid Chongqing Jiangjin Power Supply Company will rely on the opportunity of digital transformation to continue to expand the smart functions of drones, strengthen image recognition, edge computing, rapid transmission of video image data, and the integration of AI artificial intelligence technology and drone technology. It is promoted and applied in multiple scenarios such as automatic defect identification, live detection, project acceptance, channel patrol, fault finding, etc., to effectively improve the level of lean operation and maintenance of the power grid and ensure the safe and stable operation of the power grid.
