The 2023 Smart Expo will showcase the intelligent inspection drone technology of State Grid Chongqing Yongchuan Power Supply Company

On August 23, Wang Yao, a drone pilot in the intelligent inspection class of State Grid Chongqing Yongchuan Power Supply Company, was debugging the M300 drone before participating in the 2023 China International Intelligent Industry Expo. Preparation

According to the introduction, the equipment exhibited this time is an autonomous inspection system based on visual recognition, using the M300 drone, equipped with H20T, a 20x optical zoom visible light camera and a high-precision infrared thermal imaging camera to provide high-definition 4k images. Wang Yao said: "The edge computing terminal is used to visually identify and track the target in real time. There is no need for three-dimensional modeling and track planning. You only need to give a coordinate, and the drone can reach the coordinate automatic identification tower and perform zoom-refined photography. Then conduct autonomous patrols along the route.”

At the same time, this drone is also equipped with a defect recognition system, which can identify defects in real time and does not rely on the RTK network. Even in an environment without high-precision RTK network positioning, it can still conduct autonomous inspections of poles and towers through image recognition, thereby realizing smart inspections of power transmission and distribution. At present, this equipment has been put into use for autonomous inspection of transmission, transformation and distribution in the area, successfully solving the difficult problem of autonomous inspection due to frequent relocation of distribution poles and towers, as well as the problem of poor RTK network signal in field operations of transmission lines

According to reports, Chongqing Yongchuan Power Supply Company has established an intelligent inspection class. The class was established in November 2018. There are currently 71 pilots, of which 19 are professional intelligent inspection pilots and 50 are pilots from the power supply station. hand. The company has deployed 64 drones of various types, mainly responsible for the inspection and application of drones on 1,800 kilometers of transmission lines, 5,000 kilometers of distribution lines and 39 outdoor substations. It is the first to achieve 100% airworthiness in Chongqing. Units for drone inspection coverage. Last year, the company's drone inspections totaled more than 13,000 kilometers. The application of drone power inspection technology reduces the workload of front-line workers, improves inspection efficiency, and enables more accurate detection of defects, allowing targeted maintenance to ensure the stable operation of the power grid.
