Abstract: With the increasing business volume and data volume of Inner Mongolia Power Grid in recent years, it has become particularly difficult to manage massive data and extract valuable data from massive data. At the same time, the existing information system is no longer sufficient to support business and management. Therefore, making full use of modern information technology and management methods is an urgent need for current aerial inspection business and management. In response to such situations, Inner Mongolia Electric Power Aerial Inspection Company developed a three-dimensional data management platform based on the actual situation. This platform is based on virtualization technology and effectively integrates, displays and applies the overhead transmission line environment, line towers, and different inspection data, and combines Three-dimensional lidar scanning technology can truly display the spatial information relationship of overhead transmission lines in different areas and environments on a large scale, and display the status of each component of the transmission line tower in a refined and three-dimensional manner, thereby realizing data and ledger management and tower body measurement. and other basic functions.
