超高压线路走廊管理信息系统的设计与实现

Design and Implementation of EHV Transmission Line Corridor Management Information System

随着近几年国家经济的迅猛发展,用电需求的快速发展,直接导致了电网建设规模的大幅增长,超高压线路建设规模也逐渐增大。激光雷达技术的出现为实现电网维护和监察定量分析提供了一种可行的数据源,文章基于此,完成对超高压线路走廊管理信息系统的设计与实现。该系统具有以下功能:多种数据源的相互关联和集成,如基于地理信息关联实地拍摄情况,视频监控情况,多分辨率遥感影像叠加等;实现电力部门专业应用,如线间距测量、净空距离测量、电线垂度监测、塔位信息提取、交叉电线关系确定、危险区域自动探测、台帐查询关联、报表自动输出等;专业分析结果显示可视化,直观表达在系统中,让用户可以非常方便地分析结果。

Rapid development of economy and growing demand on electricity directly results in large-scale growth of power grid construction.The LiDAR technology makes sure the realization of quantitative analysis for grid maintenance and inspection.The system has the following features： a variety of data are interrelated and integrated,such as based on the situation of photographs on the spot,video surveillance,multi-resolution RS image overlay and so on;application to electric power sector,such as measurement of distance between lines,clearance distance measurement,monitoring of power lines sag,tower information extraction,cross-wiring identification,automatic exploration of dangerous area,accounting for association,statements automatic output and so on;professional analysis can be visualized in the system,which can be used easily.
