摘要
通过分析供热管网地理信息系统的数据模型,建立了供热管网的属性数据库,并且详细阐述了供热管网地理信息系统主要功能的实现过程。利用该地理信息系统能够满足供热管网管理的可视化功能,同时能够及时地修改或更新供热管网数据,查询各管道及各热力站主要信息,最重要的是当供热管网出现故障的时候,能够及时地进行事故关阀分析,加快供热管网的维修速度,保证供热管网的正常运行。
Through analyzing the data model of heating network based on GIS,the database were established,as well as the main functions of geographical information system were introduced in detail.Then this system not only could meet the visualization functions of heating network,but also modify timely or update the database,and inquire the main information of heating network.The most important is when faults of heating network occur,they will analyze in time and decide which valves of heating network should be closed.The system also can speed up the maintenance of and ensure the safe of heating network.
