供水管网时空数据模型是企业级供水信息集成管理的基础,当前供水管网时空数据模型尚未深入研究。为此,通过供水管网信息的共性时空特征分析,给出了供水管网设施、工程、维护、运行监测等时空对象共性概念的形式化定义,构建了供水管网时空数据模型,完整表达了供水管网设施、工程、维护、运行监测等信息域的时空语义;并通过供水管网运营管理业务应用,验证了所建模型的可行性与有效性。
The spatio-temporal data model of water supply network is the basis of integrated management of enterprise-level water supply information. At present, the spatio-temporal data model of water supply network has not been further studied. Therefore, through the analysis of common spatio-temporal features of water supply network information, the formal definition of common concepts of space-time objects such as water supply network facilities, engineering, maintenance and operation monitoring is given. The spatio-temporal data model of water supply network is constructed, The spatial and semantic semantics of water supply network facilities, engineering, maintenance, operation monitoring and other information fields; and verified the feasibility and effectiveness of the proposed model through the application of water pipe network operation management business.
