摘要
为解决树线矛盾对输电线路安全运行的影响,收集输电线路与树木的属性数据建立了相应的数据库,并采用Visual Basic 6.0开发软件系统,基于线路铁塔、导线和树木三者之间的空间坐标,建立了求解树木和线路导线之间空间距离的三维数学模型,根据树木的年、月和日生长率,以导线和树木之间的允许安全距离为标准,判断导线和树冠之间的最小空间距离,实现了树木修剪日期的辅助预测。
In order to solve the contradiction between trees and transmission lines,the database is established with the attribute data of transmission lines and trees.Based on the Visual Basis 6.0,the management information system for protecting distance between transmission lines and trees are developed.According to the spatial coordinates of line towers,conductors and tree crown,three-dimensional mathematical model is established to calculate the spatial distance between the conductor and tree crown.According to the tree＇s growth rate of year,month and day,taking allowable safe distance between conductor and tree crown as standard,the system can calculate the spatial distance between conductor and tree crown,which realizes auxiliary prediction the pruning date.
