Method of creating and retrieving knowledge points of circuit components based on character strings

Abstract

The invention discloses a character string-based method for creating and retrieving knowledge points of circuit components, including: selecting image information of an object circuit diagram; performing binary processing on the image; performing Hough transform on the image; and extracting components from the image and component pins; standardize and rotate the extracted components; digitize the components to obtain the unique character string corresponding to the component; convert the unique character string corresponding to the component and the corresponding text remark information Both are used as the label of the screenshot information of the component, and the label and the screenshot information of the component are stored in the knowledge point database; the knowledge point database is retrieved with a string as a parameter, and the screenshot information and text notes corresponding to the component are obtained information. The invention retrieves the design error point remark information and connection error screenshot information of components corresponding to the string in the knowledge point database in the form of character strings, and the retrieval results appear in real time, and the effect is very ideal.

Description

technical field [0001] The invention relates to the field of creating knowledge points of circuit components, in particular to a character string-based method for creating and retrieving knowledge points of circuit components. Background technique [0002] During the design and verification process of the product's circuit board drawings, various design errors will be found. In order to reduce these design errors and improve design efficiency and quality, a supporting knowledge system has been developed. When the user finds a design error, the design error drawing is saved in the knowledge system as image data and descriptive text information. At present, the existing technology is to search whether there are relevant knowledge points in the knowledge system in the form of text. The real-time performance of the search in the text form is poor, and sometimes the results can only be obtained after multiple searches, and the effect is not very satisfactory. In order to improve...
