Problems solved by technology

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 ideal.

Embodiment Construction

[0042] The following is based on figure 1 and figure 2 The specific embodiment of the present invention is further described:

[0043] The present invention provides a method for creating and retrieving knowledge points of circuit components based on character strings. The character strings corresponding to the components can be obtained according to the shapes of the components in the placed circuit diagram, so as to quickly find out whether there is relevant information.

[0044] A method for creating and retrieving knowledge points of circuit components based on character strings, comprising the following steps:

[0045] see figure 1 , create a knowledge point:

[0046] Step 1: Select the image information of the circuit diagram of the wrongly designed object;

[0047] Step 2: Binarize the image of the target circuit diagram;

[0048] Step 3: Hough transform the image of the target circuit diagram;

[0049] Step 4: Extract components and component pins from the image...

Abstract

The invention discloses a method for creating and retrieving knowledge points of circuit components based on character strings, which comprises the following steps: selecting image information of an object circuit diagram; binarizing the image;through transforming the image; extracting components and component pins from the image; the extracted components are subjected to standardized rotation treatment; carrying out graphic digitization on the components to obtain a unique string corresponding to the components; the unique character string and the corresponding text comment information of thecomponent are used as labels of the screenshot information of the component, and the labels are stored in the knowledge point database together with the screenshot information of the component. The knowledge point database is retrieved by using string as parameter, and the corresponding screenshot information and text comment information of the components and devices are obtained. The invention searches the design error point comment information and the connection error screenshot information of the components corresponding to the string in the knowledge point database in the form of string,and the retrieval result appears 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...
