Embodiment Construction

[0035] The concrete implementation process of the present invention is as figure 1 shown, including the following steps:

[0036] (1) Process the CAD basic data, cancel the drawing of the nodes, and only need to process the existing pipe sections, and use the endpoint capture tool to ensure the complete coordinate matching of the endpoint connections between the two pipe sections;

[0037] (2) Through the conversion tool "Feature Class To Feature Class" under the ArcGIS platform, the CAD pipe segment data is converted into shape format vector data with attribute fields;

[0038](3) The construction fields of GIS vector data of pipe section include: section type, pipe diameter, canal height, canal width, upstream bottom elevation, downstream bottom elevation, upstream buried depth, downstream buried depth and pipe section flow direction. The above fields can automatically obtain the text identification information near the pipe section in the CAD data through the spatial conne...

Abstract

The invention relates to a hydraulic model building demands based digital processing method for a drainage pipeline network and belongs to the crossing field of the municipal engineering information technology and the geographic information system technology. Started with hydraulic model building demands, GIS (geographic information system) operation of standard CAD (computer-aided design) vector data is greatly simplified, main operation steps are automatically implemented through computers, errors of original data can be authenticated in time by the aid of a debugging mechanism, and digital processing of the drainage pipeline network system can be quickly and accurately realized. The hydraulic model building demands based digital processing method has the advantages that data size inputted manually by conventional processing methods is greatly simplified, flow direction information of pipeline sections is the only thing to determine, and complicated operations of inputting upstream and downstream node numbers of the pipeline sections are eliminated. Meanwhile, operability of various steps is taken into consideration, the steps can be implemented only by the aid of simple operations on the GIS platform instead of complicated procedural programming, and implementation of the digital processing method is guaranteed.

Description

technical field [0001] The invention relates to a digital processing method for a drainage pipe network based on hydraulic model construction requirements, and belongs to the intersection field of municipal engineering information technology and geographic information system technology. Background technique [0002] As an important part of urban construction, underground drainage pipe network plays an important role in urban planning and construction. With the acceleration of urbanization, the scale of underground pipe network construction is gradually expanding, and the data of pipe network is constantly updated. The information management of the pipe network system has brought more and more difficulties. At present, the management mode of my country's pipe network data is still in the stage of mainly CAD data and text data, and there has been a lack of effective technical means to realize the description of the spatial attributes and topological relationships of the pipe n...
