摘要/Abstract

摘要： 输电线路作为电力资源长距离输送的主要载体,对其运行状态精细化巡检是电网运行管理及风险评估的重要手段,但当前输电线路巡检存在自动化程度低、效率低等技术难点。本文联合无人机载LiDAR高精度的空间位置信息和GIS强大的三维空间分析功能,通过对点云数据精细分割、单个地理实体结构化建模等点云数据处理与GIS系统开发等内容的研究,构建了基于机载激光点云的输电线路本体要素精细化三维模型,研发了基于GIS系统的输电线路安全隐患点智能化检测系统,形成了LiDAR+GIS输电线路安全巡检技术应用。工程应用及效果评价结果表明,LiDAR+GIS技术可实现输电线路安全隐患点快速检测,具有巡检精细、效率高等优势。本文可为电网数字化建设及升级改造、减灾防灾等应用提供更真实的空间数据基础和技术方案。

Abstract: As the main carrier of long-distance transmission of power resources, fine inspection of the operation status of transmission lines is an important means of power grid operation management and risk assessment. However, there are technical difficulties in the current inspection of transmission lines, such as low automation and low efficiency. The paper combines the high-precision spatial position information of LiDAR carried by unmanned aerial vehicles and the powerful 3D spatial analysis function of GIS. Through the research of point cloud data processing and GIS system development, such as fine segmentation of point cloud data and structured modeling of individual geographic entities, a refined 3D model of transmission line body elements based on airborne laser point cloud is constructed. An intelligent detection system for transmission line safety hazards based on GIS system is developed, forming the application of LiDAR+GIS transmission line safety inspection technology. The engineering application and effectiveness evaluation results show that LiDAR+GIS technology can achieve rapid detection of safety hazards in transmission lines, with advantages such as fine inspection and high efficiency. Research provides a more realistic spatial data foundation and technical solutions for the digital construction and upgrading of power grids, disaster reduction and prevention applications.
