摘要
为了解决电力地下管网管理系统数据更新过程中原始管线数据与普查管线数据路径不一致的问题,借鉴道路匹配模型提出基于最小二乘法建模的电力地下管线匹配算法。该算法首先对管线进行插值处理,然后计算电力地下管线间的管线特征值,再次提取每对原始管线以及普查管线的管线对特征,最后进行归一化特征比较,根据比较结果决定是否进行管线匹配,进而更新管线路径。实验结果表明,该算法能够有效准确地处理新旧电力管线的路径匹配问题。
In order to solve path inconsistency between the original pipeline data and the census pipeline data path in the data updating process of the power underground pipeline network management system, this paper proposes a power underground pipeline matching algorithm based on the least square method refer to road matching method. Firstly, the algorithm interpolate the pipelines, and calculates the features of the pipelines in the power underground pipelines, then extracts the pipeline pairwise features of each pair of original pipelines and census pipelines, finally compare the normalized pipeline pairwise features, and decides whether to match the pipelines and updates the pipeline route according to the comparison results. Experimental results show that the algorithm can deal with the path-matching problem of new and old power lines efficiently and accurately.
