Embodiment 1

[0032] refer to figure 1 , a method for constructing a PCB fault diagnosis rule base provided in this embodiment mainly includes acquisition of fault language, lexical analysis, syntax analysis, semantic analysis and construction of a rule base.

[0033] In this embodiment, the rule base is the CLIPS rule base, and the acquisition of the fault language is mainly determined according to the standard, and in this embodiment, the standard is the IPC-D-279 standard in the PCB field; the lexical analysis is mainly the PCB field Commonly used phrases and tenses are included in the dictionary and then matched; syntactic analysis is mainly to determine the subject, predicate and object in the fault sentence, and obtain the type of verb in the predicate; semantic analysis is mainly to perform different semantic matching according to different verb types and judgment.

[0034] refer to figure 2 , in this embodiment, the acquisition of the fault language is mainly the construction of ...

Embodiment 2

[0049] Different from embodiment one, the semantic analysis in embodiment one is simple sentence semantic analysis, and the semantic analysis in embodiment two is compound sentence semantic analysis, refer to Figure 6 , which is different from the semantic analysis of simple sentences in that the semantic analysis of compound sentences decomposes compound sentences into multiple simple sentences, and uses the method of circular processing of simple sentences to perform semantic analysis on each simple sentence. According to the results of syntactic analysis, fill in the verbs in their corresponding semantic frames. If the verb does not meet the requirements of the three types of verb semantic frames, fill in the next verb semantic frame until all the verbs complete the above actions. Next, a verb semantic frame is extracted to perform semantic analysis according to the processing method of a simple sentence, and its semantic template is filled until the analysis of all verb se...

Embodiment 3

[0051] In this embodiment, the present invention also provides an electronic device, including: one or more processors; storage device for storing one or more programs, when one or more programs are executed by one or more processors , so that one or more processors implement the PCB fault diagnosis rule library construction method as in Embodiment 1 or 2.

Abstract

The invention relates to the technical field of intelligent language processing, in particular to a construction method of a PCB fault diagnosis rule base, electronic equipment and a storage medium thereof. The PCB fault diagnosis rule base construction method comprises the steps of obtaining a plurality of fault statements of an execution object, performing grammatical analysis on the plurality of fault statements to determine a verb type, filling a semantic framework with a grammatical analysis result according to the verb type, performing semantic analysis on information in the semantic framework to obtain risk information, and storing the risk information in a semantic template form, and converting the information in the semantic template into a target language to obtain a fault aiming rule base. According to the PCB fault diagnosis rule base construction method and the established rule base provided by the invention, the diagnosis of the fault of the PCB based on the natural language can be realized, the PCB information in the IPC standard can be applied to the fault diagnosis to a greater extent, and an important reference significance is provided for the construction of an expert system knowledge base in the future.

Description

technical field [0001] The invention relates to the technical field of intelligent language processing, in particular to a method for constructing a PCB fault diagnosis rule base, electronic equipment and a storage medium thereof. Background technique [0002] With the rapid development of electronic technology, electronic products have become miniaturized and multi-functional, and the application range of electronic products has become wider and wider, which makes the requirements for reliability of electronic products higher and higher. Printed circuit board (PCB, Printed Circuit Board) is an important component of electronic products, and its design is becoming more and more complex. The reliability of electronic products depends largely on the reliability of PCB, therefore, it is very important to evaluate the reliability of PCB. The existing PCB reliability assessment mainly adopts two methods of modeling and testing, which can no longer meet the needs of practical eng...
