中文摘要：

以新疆地区的极端环境为背景,针对目前输电线路巡检效率低下等问题,选取新疆某地区的历史巡检数据,详细介绍了利用C5.0算法对该数据进行自动提取、分类的过程,构建了输电线路巡检评估决策树,并从中提取了一些重要信息。研究方法和结果可为输电线路巡检人员制定巡检计划提供参考。

英文摘要：

Based on the extreme environment in Xinjiang,aiming at the inefficiency in the inspection of transmission lines,this paper introduces the automatic extraction and classification progress of C5.0 algorithm of the historical inspection data of a region in Xinjiang,and then establishes the power transmission line inspection evaluation decision tree and obtains some important information. The research methods and results in this paper can provide some rewarding reference to the transmission line inspectors in the making of the inspection plan.
