Embodiment 1

[0052] Please refer to figure 2 , Embodiment 1 of the present invention is: a method for modeling distribution network line diagrams, which can be applied to GIS data modeling in distribution network line engineering, including the following steps:

[0053] S1: Obtain the standard graphic elements of the power grid equipment, that is, the national grid standardized graphic element data, which is used for subsequent matching and identification of the CAD drawings of the as-built drawings of the distribution network lines. Graphic element is the solidified icon of each device, which is the basic unit of engineering drawings. In this embodiment, the power grid equipment includes tower equipment, switchgear, pole-mounted transformers, wire equipment, cable equipment, and cable terminals, ie, power grid equipment of the distribution network.

[0054] S2: Load the as-built drawing of the distribution network line, and establish a preset coordinate system in the as-built drawing of...

Embodiment 2

[0072] This embodiment is a specific application scenario of Embodiment 1.

[0073] The automatic modeling tool integrates the standard metadata of the State Grid distribution network and integrates CAD image recognition technology.

[0074] After receiving the as-built drawings of the distribution network line project, the GIS modelers of the power grid need to model the project. The modeler opens the automatic modeling tool and imports the as-built drawings. Through the CAD image recognition technology, the system compares the drawings according to the standard graphic metadata, identifies and generates corresponding equipment data and topological relationships, and stores them in the database. After the identification is completed, the system draws the project path diagram according to the generated equipment data and equipment topological relationship. The modeler checks the project path diagram according to the actual situation, supplements the missing equipment, specif...

Embodiment 3

[0076] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0077] Obtain the standard graphic elements corresponding to the grid equipment, and load the as-built drawing of the distribution network line;

[0078] Identify the as-built diagram of the distribution network line according to the standard graphic element data, obtain a grid equipment graphic, and generate equipment data corresponding to the grid equipment graphic, and the equipment data includes location information and a connected equipment set;

[0079] Generate a line path diagram according to the equipment data corresponding to the grid equipment graphics and the standard graphic elements;

[0080] Edit the data in the pre-modeled area according to the line path diagram.

[0081] Further, the grid equipment graphics include point equi...
