【摘要】 针对供水管网巡检系统,通过分析供水管网巡检业务时空特性,研究类比空间模型的"面向对象法",细化巡检对象,抽象定义管网巡检要素,完整表达供水管网巡检系统各要素时空语义,提出供水管网巡检系统的时空数据模型和数据库模型。结果表明,基于时空数据模型的供水管网巡检系统,可以实现巡检系统点、线、面基本时空对象在时空维度上有序组织,更加贴近供水企业管理与综合运营的需求,优化供水管网巡检业务,从而以智能高效管理和科学理解业务属性为应用目标,提高管网安全运行和管理水平,有效保证了供水管网高效率、低故障运行。更多还原

【Abstract】 Through analyzing the spatiotemporal characteristics of water supply network inspection,studying the object-oriented method of analogical space model,refining the inspection targets,creating the abstract definition of pipe network inspection elements,and fully expressing the spatiotemporal semantics of every element in water supply network inspection system,a spatiotemporal data model and a database model of the water supply network inspection system were proposed. The results showed that the inspection system achieved an orderly organization in the space-time dimensions for the basic point,line,and surface spatiotemporal features. The organization had satisfied the demands in water supply enterprise management and comprehensive operation,and optimized the inspection service of the water supply network. Taking the intelligent and efficient management and the scientific understanding of business attributes as the application goal,the proposed models could improve the safe operation and management level of the pipe network,and ensure a highly efficient and reliable operation of the water supply network.更多还原
