Problems solved by technology

[0019] - It takes a lot of manpower and material resources
Especially if it is necessary to input the distribution network design circuit in CAD format of the low-voltage line into the GIS system, the workload is huge and it is difficult to achieve by manpower
[0020] - The accuracy of the data is also difficult to guarantee
Errors are inevitable due to manual data identification and entry

Embodiment Construction

[0076] A method for automatic identification of distribution network AUTOCAD design drawings, including the establishment of a sample database and the identification of equipment in CAD design drawings, such as figure 2 Shown:

[0077] 1) The establishment of the sample database includes:

[0078] - Establishment of standard samples of various equipment;

[0079] - Generate standard samples of various devices at different angles, for example, each device is rotated to different angles, and a total of 16 samples are generated;

[0080] -Collect standard samples of various equipment and establish a database.

[0081] Step 1) The specific process of establishing the sample database is as follows:

[0082] First, convert each device drawn on the CAD drawing into a combination of points and lines.

[0083] These points describe the outline of the device, which are feature points.

[0084] These lines describe the connection relationship of these feature points.

[0085] Poin...

Abstract

The invention aims to provide an automatic distribution network AUTOCAD design drawing identification method. The method can automatically import the distribution network design drawings in a CAD format into a GIS system, and then identify various devices of the distribution network in the GIS system. The method comprises two processes: creation of a sample database and identification of the devices in the CAD design drawings. The automatic distribution network AUTOCAD design drawing identification method, disclosed by the invention, can automatically identify the devices in the CAD design drawings with high identification rate; as the CAD design drawings and device identification are processed automatically by a program, the method is faster in processing speed and more convenient, and meanwhile solve the problem that the manual manner causes inaccurate data.

Description

technical field [0001] The invention relates to the technical field of distribution network planning and design, in particular to an automatic recognition method for an AUTOCAD design drawing of a distribution network. Background technique [0002] Now the planning and design of distribution network is generally completed by engineers with AUTOCAD or other similar tools. The format of the generated design drawing is CAD format. At the same time, the lines of the distribution network generally need to be managed and displayed in the geographic information system (GIS). Therefore, professional personnel are required to redraw these distribution network design drawings in CAD format into the GIS. For example: CAD designers draw such figure 1 The graph shown represents a certain equipment in the distribution network, so the GIS developer needs to redraw the diagram of a certain equipment into the GIS system according to the content of the CAD drawing. [0003] If the design d...
