供水管网多源数据融合探讨

Discussion on the Multiple Data Fusion of Water Supply Pipeline Network

城市供水管网数据主要来源于城市地下管线普查、专业管线调查和竣工测量,其存储形式主要分为电子和纸质等,数据格式分为shp格式、dwg格式以及纸质文档等。其属性数据各有侧重,普查数据主要侧重管线的空间位置、空间关系等本体属性,重点在为了满足城市建设、城市规划的需要;而专业管线调查数据则主要侧重管线设施设备属性、管线建设和运行、维护等属性,为了满足管线安全运行和日常管理的需要;竣工图数据则保护管线空间位置、管线设施设备型号、管线接口等,为了满足管线设施管理需要。本文以供水管线为实例,提出了供水管网多源数据融合,构建供水管网综合数据库,满足供水管网日常运维的需要。

The data of urban water supply network mainly comes from urban underground pipeline survey,professional pipeline survey and construction completion survey.Its storage form is mainly divided into electronic and paper.The data format is divided into shp format,dwg format and paper documents.Its attribute data has its own emphasis.The census data mainly focuses on the ontology attributes such as spatial location and spatial relationship of pipelines,which meets the needs of urban construction and urban planning.The professional pipeline survey data mainly focuses on the attributes of pipeline facilities and equipment,pipeline construction,operation and maintenance,in order to meet the needs of pipeline safe operation and daily management.The construction completion data protects the spatial location of pipelines,models of pipeline facilities and equipment,pipeline interfaces,etc.,in order to meet the needs of pipeline facilities management.Taking the water supply pipeline as an example,this paper puts forward the multi-source data fusion of water supply network and constructs the comprehensive database of water supply network to meet the needs of daily operation and maintenance of water supply network.
