Core Viewpoint - The introduction of the "E-Dian Hui Tu" software significantly enhances the efficiency of drone route planning and inspection applications in substations, marking a breakthrough in the industry for intelligent inspection development [1][2]. Group 1: Software Development and Features - The "E-Dian Hui Tu" software is the first domestic three-dimensional modeling and drone route planning software specifically designed for substation operation and maintenance personnel, developed by the State Grid Hubei Electric Power Company [1]. - The software integrates "point cloud + real scene" modeling technology, combining the visualization of real scenes with the high precision of point clouds to meet route planning and safety verification needs [1]. - It employs a second-generation modeling technology based on 3D Gaussian algorithms, which enhances model accuracy and visualization effects [1]. Group 2: Implementation and Impact - As of late June 2023, Hubei Electric Power has activated 309 sets of the "E-Dian Hui Tu" software, completing modeling for 693 substations and route planning for 657 substations [2]. - The implementation of this software has led to significant cost reduction and efficiency improvement in the core business of intelligent drone inspections in the power industry, providing a successful example for the sector [2].
