供水管网异构数据集成共享关键技术研究

Research on Key Technology in Integrating and Sharing of Water Supply Pipe Network Heterogeneous Data

针对供水管网存在数据异构和管网信息共享时语义表达不一致,特别是数据集成时单一相似度计算方法精度较低的问题,设计了具有语义一致的供水管网集成数据模型,提出综合相似度计算方法,进而构建了异构数据的模式和数值映射关系,并以MapGIS为开发平台,实现了语义一致的供水管网数据集成与共享发布。实践表明,研究成果可满足供水管网异构数据集成与共享的应用需求,可为其他行业管网数据集成和共享建设提供参考。

Aiming at the problem that there are data heterogeneity and inconsistency in semantic expression between water supply pipe networks, especially for the problem of low accuracy of single similarity calculation method, the semantic consistent integrated data model is firstly designed and a comprehensive similarity calculation method is proposed to build mapping relationship. Then the integration of heterogeneous data is implemented and the semantic consistent data based on MapGIS SDK is published. The practice shows that the proposal can meet the demand of the integration and sharing of water supply network data, and has reference value for the integrating and sharing of pipe network data in other industry.
