Water supply pipe network management and hydraulic model construction method by using open source GIS and database

Abstract

The present invention belongs to the technical field of municipal engineering water supply pipe network information. In order to overcome the deficiencies of the prior art, the present invention aimsto propose a water supply pipe network model construction method, which has a simple structure, good performance, and a low cost. The technical scheme of the present invention is a water supply pipe network management and hydraulic model construction method by using an open source GIS and a database. The method comprises the following steps: (1) for a pipe section, a node, and a reservoir layer that are necessary for a water supply pipe network, rationally designing attribute fields thereof; (2) using open source QGIS (Quantum GIS) desktop software to manage data and maps of the water supply pipe network, and to implement data entry and editing functions and query and statistics functions; (3) using open-source PostGIS geodatabases to store water pipe network data; (4) inputting the conversion of files to the EPANET; and (5) carrying out hydraulic simulation and calculation. The method provided by the present invention can be mainly applied to information processing occasions of a municipal engineering water supply pipe network.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering water supply network information, and specifically relates to a method for constructing a water supply network management system and a hydraulic model based on open-source GIS and open-source database technologies. Background technique [0002] The data volume of underground pipelines is huge. In the past, management was based on paper drawings and documents, and the maintenance was complicated and inefficient. With the continuous deepening of our country's informatization, advanced management methods based on computer technology have been continuously introduced into all walks of life. For example, the management system based on GIS (Geographic Information System, Geographic Information System) has been applied to various aspects of municipal pipelines, such as water supply pipeline network, reclaimed water pipeline network, city gas pipeline network and so on. [0003] The GIS wat...
