T/YDHX 003-2024 The technical specification for 3D laser modeling and automatic inspection of overhead transmission lines using multi-rotor drones
Basic Information
Scope
Scope: This specification applies to small and medium-sized multi-rotor drones equipped with three-dimensional laser radar scanning devices for measuring internal and external works, including the basic requirements for drone laser radar data collection and processing for power line inspection, data content, fine inspection, quality control, results acceptance, and technical requirements and operational requirements for automatic inspection of overhead transmission lines with voltages of 35kV and above. This document specifies the scope, steps, and methods for laser radar collection for internal and external works and automatic inspection of overhead transmission lines with drones, and is applicable to areas where line characteristics analysis has been completed. Main technical content: This standard is divided into six chapters, including scope, normative reference documents, terms and definitions, three-dimensional laser modeling, automatic inspection, and appendices (A~T). The standard applies to small and medium-sized multi-rotor drones equipped with three-dimensional laser radar scanning devices for measuring internal and external works, including the basic requirements for drone laser radar data collection and processing for power line inspection, data content, fine inspection, quality control, results acceptance, and technical requirements and operational requirements for automatic inspection of overhead transmission lines with voltages of 35kV and above.
