Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] In order to solve this technical problem, according to the attached Figures 1 to 2 , to give a detailed description of the steps and functions of the GIS-based hydraulic model results symbolic dynamic display method;

[0032] A GIS-based hydraulic model result symbolic dynamic display method, the method includes the following steps:

[0033] S1: Convert the Inp file of the EPANET hydraulic model into the Shp file corresponding to each pipe network model object, and establish the corresponding relationship between the GIS data and the Inp file;

[0034] First, create the Shp file of each object corresponding to the water supply pipe network model in ArcGIS, input the attribute field corresponding to the Inp pipe network elements, and then perform automatic analysis, identification and reading of the pipe network elements on the Inp file, and convert a...

Abstract

The invention relates to a crossing field of an engineering technology and a geographic information engineering technology, in particular to a hydraulic model result symbolization dynamic display method and system based on a GIS, and the method comprises the following steps: S1, converting an EPANET hydraulic model Inp file into Shp files corresponding to all pipe network model objects, and building a corresponding relation between GIS data and the Inp files; S2, setting and adjusting hydraulic model parameters, calling an EPANET calculation library for hydraulic simulation calculation, and writing a calculation result into a Hash table to cache simulation time sequence data; S3, calling a unique value rendering interface in an ArcGIS secondary development component library to perform hierarchical rendering and dynamic display on simulation result time series data. The invention discloses a hydraulic model result symbolization dynamic display method and system based on a GIS. The system comprises an Inp file import module, a water supply hydraulic model parameter setting module, a hydraulic model simulation calculation module and an operation state time dynamic graph display module.

Description

technical field [0001] The present invention relates to a cross field of engineering technology and geographic information engineering technology, more specifically a GIS-based method and system for symbolizing and dynamically displaying hydraulic model results. Background technique [0002] The water supply network system is a network system with complex topology, large scale, strong randomness of water use change, and multi-objective operation control. As an important infrastructure of the city, it is closely related to people's life and work. In order to ensure the quality of water supply, it is an important task to track the operation status of the water supply network system in real time. The establishment of the hydraulic model of the water supply network provides the possibility for real-time tracking of various indicators in the network. [0003] Generally, the establishment of a hydraulic model will import the collected dynamic and static attribute data of the wate...
