Abstract

The invention discloses a data preprocessing method and system for intelligent identification of an electrical drawing, and the method comprises the steps: carrying out the first preprocessing of a text of the electrical drawing, and obtaining processed text data; carrying out second preprocessing on the arc of the electrical drawing to obtain processed arc data; performing third preprocessing onthe straight line of the electrical drawing to obtain processed straight line data; carrying out fourth preprocessing on the circle and the ellipse of the electrical drawing to obtain processed circleand ellipse data; and filtering the drawing label of the electrical drawing to obtain processed drawing label data. According to the invention, the preset method is used for carrying out data preprocessing on the electrical drawing, data preprocessing or filtering processing is carried out on texts, arcs, straight lines, circles, ellipses and drawing tags in the drawing, and due to the fact thatthe drawing data is preprocessed, the accuracy and the recognition efficiency of a subsequent intelligent recognition algorithm are remarkably improved. The method and systemcan be widely applied to the technical field of artificial intelligence in the electrical industry.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence in the electrical industry, in particular to a data preprocessing method and system for intelligent identification of electrical drawings. Background technique [0002] In the electrical industry, complete sets of electrical quoters need to give quotations for complete sets of electrical equipment based on the CAD electrical design drawings obtained from users. Listing the list according to the CAD drawings given by the user is the most important part of the quotation and the basis for the complete electrical quotation. As a somewhat boring and cumbersome link that requires a certain amount of domain knowledge, the traditional quotation method for complete electrical quotations is mainly to extract the text of the components by manually inputting Excel or using software, and list the list. Then summarize the quotation list, and finally make a quotation based on such a list. [00...
