Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0055] refer to figure 1 , this embodiment discloses a method for identifying a distribution box based on an electrical drawing, and the method can be executed in a computer or a processor.

[0056] The method of the present embodiment comprises the following steps:

[0057] S1. Obtain electrical drawings. The electrical drawings can be CAD drawings, pictures of electrical drawings or electrical drawings in other formats, but the electrical drawings should be standardized electrical drawings.

[0058] S2. Identify horizontal lines and vertical lines from the electrical drawing. This step can be identified by means of image recognition, and elements can also be directly read in electrical drawings in formats such as CAD. Among them, the horizontal line and the vertical line are relative concepts, which are related to the direction of the dra...

Abstract

The invention discloses a method and a device for identifying a distribution box based on electrical drawings. The method comprises the following steps: obtaining electrical drawings; Identify horizontal and vertical lines from electrical drawings; Identifying a wire from a horizontal line; Identifying a centerline from a vertical line; Constructing a tree structure according to the number of electric wires connected to the left and right sides of the center line and the number of horizontal wires connected to the left and right sides of the center line and not recognized as electric wires; Acquiring a graph range of a tree structure, and then acquiring text content within the graph range; According to the content of the text and the number of wires in the tree structure, whether the treestructure is a distribution box is judged, and the recognition result of the distribution box is obtained. The invention directly identifies the electric wire and the middle line in the electric drawing, constructs a tree structure by using the electric wire and the middle line, and further judges whether the tree structure belongs to the distribution box, thereby obtaining the identification result of the distribution box, and the invention has higher efficiency than manual identification. The invention can be widely applied in the field of artificial intelligence.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method and device for identifying a distribution box based on electrical drawings. Background technique [0002] In the electrical industry, the quotation clerk needs to give a quotation for the complete set of electrical equipment in the drawing according to the electrical drawing obtained from the user. The quotation clerk needs to list the quotation list of each distribution box according to the electrical drawing, and finally summarize and give all List of quotations for distribution boxes. The detection and positioning of distribution boxes is a very basic but particularly important task in these quotation tasks. [0003] At present, in the electrical industry, these distribution boxes are mainly located manually, which is very inefficient. Contents of the invention [0004] In order to solve the above technical problems, the object of the present invention is to...
