中文摘要：

针对目前城市供水的低下效率和漏损严重的情况，给出了一整套供水管网管理和漏损实时监测的系统设计方案，包括数据获取模块、监测及异常处理模块、流量计管理模块、流量统计分析模块、用户及权限管理模块等，对每个模块进行了详细分析和设计并在最后给出了数据库的设计。在漏损监测方面，提出了一种扩展多叉树数据结构来模拟环状管网，实现了流量计的分级漏损检测，为其它功能实现提供了支持；在用户管理模块中，对传统的基于角色的权限管理模型进行了分层次和带地理信息扩展。

英文摘要：

To copy with the low efficiency and the serious leakage of the water supply network, a whole design solution for auto- matic management and real-time leakage monitoring is provided. This proposed system is consisted of data acquisition module, monitoring and exception processing module, flow meter management module, {low statistics and analysis module, users and ac- cess control management module and so on, and every module is analyzed and designed in detail. Finally, the design of the data- base is also discussed. In the leakage detection, an extended multi-tree data structure is put forward to simulate the loop pipe network, and helps to realize the function of leakage detection by level and other functions. Also in the user management module, the traditional role-based access control model is extended with gradation and area information.
