The method includes the steps of 1, converting a CAD (computer-aided design) drawing of a water supply network in a whole area into a network model topological structure and generating a target INP file; 2, converting pipeline diameter layers of the CAD drawing of the water supply network in the whole area into another network model topological structure, and generating INP source files; 3, opening the target INP file, loading programming software to write codes, acquiring coordinates (X1-Coord, Y1-Coord) and (X2-Coord, Y2-Coord) of upstream and downstream nodes Node1 and Node2 of each pipeline in each INP source file, finding the nodes with the same coordinates from the target INP files by the traversing method, finding the corresponding pipelines through the found nodes, and assigning values of pipeline diameters to the pipelines in the target INP files.
Description
Technical field
The present invention relates to the water supply network method for establishing model of Water and Waste Water Engineering, being particularly applicable to derives that network topology carries out pipe net modeling and without modeling and the generation method of pipeline section attribute problem by CAD.
Background technology
Water supply network is a topological structure complexity, network system in large scale.Network topology to set up workload huge.In addition, the correctness of network topology will directly affect the accuracy of simulation.For large and medium-sized water supply network modeling, only depend on the topological structure of artificial input almost to become not achievable task.For the foundation of pipe network model, generally adopt in the pipeline configuration ingress pipe pessimistic concurrency control in existing CAD, form network topology.But, from the topological structure of CAD ingress pipe pessimistic concurrency control, lack pipe diameter attribute, and it is very big that every pipeline is carried out to diameter input service amount, restriction water supply network modeling efficiency.
Summary of the invention
The object of the invention is to deficiency and defect for existing water supply network modeling disappearance pipe diameter attribute, provide a kind of water supply network topological structure rapid generation based on INP file, to address the above problem.
Technical matters solved by the invention can realize by the following technical solutions:
Water supply network topological structure rapid generation based on INP file, is characterized in that, comprises the following steps:
(1) the water supply network CAD figure in whole region is converted to pipe network model topology structure, and generates INP file, set it as target INP file;
(2) each pipe diameter figure layer in the water supply network CAD figure in whole region is converted to pipe network model topology structure, and generates respectively INP file, set it as INP source file;
(3) in target INP file, open data, carrying out code by loading programming software writes, in each INP source file, for upstream and downstream node Node1, the Node2 of each pipeline, obtain the coordinate (X1-Coord of its node, Y1-Coord), (X2-Coord, Y2-Coord), by the method for traversal, in target INP file, find the node with same coordinate, and find out corresponding pipeline by place node, pipe diameter assignment, in the pipeline of target INP file, is completed to the pipe diameter assignment to target INP file.
In a preferred embodiment of the invention, in step (3) afterwards, delete the caliber assignment data of the INP source file in this target INP file, and preserve.
In a preferred embodiment of the invention, the programming software in described step (3) is Visual Basic for Application or Visual C++.
Owing to having adopted technical scheme as above, simple operation of the present invention, practical, Diameter of Feed Water Pipe attribute be can input quickly and accurately, thereby high efficiency and the accuracy of water supply network modeling greatly strengthened.Reduce hand labor intensity, increase work efficiency, along with urban water supply is information-based and the continuous popularization of feedwater modeling, the present invention can be more widely used.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the principle flow chart of an embodiment of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Shown in Figure 1, the water supply network topological structure rapid generation based on INP file comprises the following steps:
(1) whole region pipe network CAD figure is converted to pipe network model topology structure, and generates INP file, set it as target INP file.
(2) each caliber figure layer (as DN300, DN400 etc.) in the water supply network CAD figure in whole region is converted to respectively to pipe network model topology structure, and generates respectively each caliber INP file, set it as caliber assignment INP source file.
(3) target INP file and caliber assignment INP source file are opened by EXCEL, and the data Replica in each caliber assignment INP source file is arrived to the blank space of target INP file.Load program by Visual Basic for Application or Visual C++, and write code, operation, thus realize the assignment of each pipe diameter.The network topology of deriving for same cad file, each pipe network node coordinate X, Y are identical.In caliber assignment INP source file, for upstream and downstream node di_node1, the di_node2 of each pipeline, obtain coordinate (X1-Coord, Y1-Coord), (X2-Coord, the Y2-Coord) of its node; By the method for traversal, in target INP file, find and there is same coordinate (X1-Coord, Y1-Coord), (X2-Coord, Y2-Coord) node all_node1, all_node2, and find out place pipeline section by node, its pipeline section is the corresponding pipeline that need to give diameter of caliber assignment INP source file, and gives this pipeline at Diameter place by diameter value.
(4) in target INP file by after all pipe diameter assignment, delete the caliber assignment INP source file data in this file, and preserve.When occur inquiry whether remove after incompatible form, then preserve dialog box time, click "Yes".
Simple operation of the present invention, practical, Diameter of Feed Water Pipe attribute be can input quickly and accurately, thereby high efficiency and the accuracy of water supply network modeling greatly strengthened.Reduce hand labor intensity, increase work efficiency, along with urban water supply is information-based and the continuous popularization of feedwater modeling, the present invention can be more widely used.
