1引言盘活线路的存量资产,提高资源利用率,是提高线路综合效能的重要保证。在电缆线序的管理上,一直存在数据资料与实际不符现象,长期累积使得数据资料的差错率越来越大,因此需要对线路资料进行大规模普查。采用人工方式普查线路资料,不但工作量大、耗时长,而且准确性得不到保 1 Introduction Activation of the existing stock of assets, improve resource utilization, is an important guarantee to improve the overall efficiency of the line. In the management of cable line sequence, there is always the phenomenon of inconsistency between the data and the actual data. The long-term accumulation leads to an increasing error rate of the data and therefore requires a large-scale survey of the data of the line. The manual survey of route information, not only the workload, time-consuming, and accuracy can not be guaranteed
