摘要
介绍了基于WebGIS的城市供水管网信息系统的体系结构、功能组成以及供水管网建模技术。城市供水管网系统主要包括管网建模、查询统计、爆管事故分析、运行状态监控、漏损分析、系统维护等六个方面。城市供水管网建模是进行城市供水系统规划、设计、分析与优化调度的重要支撑技术,充分发挥WebGIS的分布式与可视化地理空间信息分析的优势,结合城市供水管网的管理需求,将WebGIS技术应用到城市供水管网的建模中。该系统可为城市供水部门的高效管理提供决策依据。
The architecture, functional composition and modelling technique of water supply network of WebGIS-based city water supply network information system are described in this article. The city water supply network system consists of 6 aspects：network modelling, query statistics,bursting accident analysis, operational status monitoring, leakage loss analysis and system maintenance. City water supply network modelling is the important fundamental supporting technology for city water supply system in planning, designing, analyzing and optimized scheduling. WebGIS is applied in modelling city water supply network by exploiting its advantages of distributed and visualized geospatial information analysis to the full and in combination with the management requirement of city water supply network. This system can provide decision basis to city water supply authorities for their efficient management.
