Since the beginning of this year, Nanhui EHV Co., Ltd. has been actively using helicopter inspection lines such as airborne LIDAR. Up to now, it has completed the 3-D laser scanning operation of approximately 5,500 km of main grid lines. Over 3,600 hidden troubles have been found, including emergency risks 105, 638 major hidden dangers, effectively prevent the tree caused by the line trip. South Network Ultra-high pressure company launched in 2008 to send the main grid power transmission lines west of the helicopter patrol line, so far accumulated patrol mileage has exceeded 100,000 km, annual patrol mileage of 25,000 km. In recent years, South Network Ultra-high pressure companies continue to strengthen the new technology and new equipment in the helicopter patrol in the research and application, which greatly enhance the helicopter patrol effect. The first is the development and application of an airborne lidar capable of being synchronized with the inspection system of a conventional photovoltaic pod, which can obtain a variety of data information such as infrared images of power equipment, visible images and laser point clouds of transmission line corridors through a single flight operation. Second, the intelligent distance measurement system for transmission line based on airborne lidar has been developed to realize the functions of panoramic channel display, safety evaluation and early warning analysis of dangerous points. Thirdly, it improved the data management system of the tour patrol and formed a complete set of mechanisms for data collection, processing, analysis and feedback from the tour patrols. It set up a tour patrol data analysis team to realize the real-time processing of tour patrol data and timely feedback to improve the route Defect verification and processing timeliness, to ensure the stability of the main grid line operation. It is reported that in 2018, South Network will be equipped with high pressure on all helicopters equipped with airborne laser radar equipment, helicopters in all regions to achieve full coverage of three-dimensional laser scanning job.
