[0044] Exemplary Methods

[0045] Figure 1 is a flow chart of a method for comparing the technical standards of power transformers based on a knowledge graph according to an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as Figure 1 As shown, the knowledge graph-based power transformer technical standard differentiation comparison method 100 includes the following steps:

[0046] Step 101, determining the technical standards of the power transformer according to the collected technical standards related to the power transformer, and converting the technical standards into text to generate text technical standards;

[0047] Step 102, performing a first preset level decomposition according to the text technical standard to generate predetermined format technical contents of each level, wherein the first preset level includes: chapter level, clause level, first technical requirement item level and content level;

[0048] Step 103, disassembling the power transformer equipment into a second preset level, generating equipment content of each level in a predetermined format, wherein the second preset level includes: equipment level, component level, second technical requirement type level, and technical requirement item level;

[0049] Step 104, using knowledge graph technology to associate the predetermined format technical content with the first technical requirement item level content of the predetermined format equipment content and the second technical requirement item level content, to construct a power transformer technical key point system;

[0050] Step 105, using the knowledge graph query language to search for multiple technical requirements of the structure to be searched from the power transformer hierarchical technical point system, and compare the multiple technical requirements to form differentiated technical standards for the structure to be searched, wherein the structure to be searched includes: equipment, components and technical requirements items.

[0051] Specifically, the present invention proposes a method for comparing the technical standards of power transformers based on knowledge graphs, aiming to solve the problems of 1) the inability to systematically and comprehensively mine and regularize the cross-repetitive contradictions between standards; and 2) the large workload of repetitive differentiated comparisons. By constructing a method for comparing the technical standards of power transformers based on knowledge graphs, a method for quickly and comprehensively sorting out the differentiation of technical standards of power transformers can be realized.

[0052] In order to overcome the above defects and improve the application effect of the power transformer fault tree, the present invention provides a method for comparing the technical standards of power transformers based on knowledge graphs, which collects and organizes 93 technical standards related to power transformers; converts the PDF versions of the 93 technical standards of power transformers into text through OCR and performs manual proofreading; analyzes the clauses of the proofread Word versions of the technical standards of power transformers; establishes a hierarchical technical point system of power transformers based on knowledge graph technology; and queries the differentiated nodes of the technical standards of power transformers based on SPARQL. .

[0053] The specific scheme provided by the present invention is as follows:

[0054] Step 101, collecting and collating 93 technical standards related to power transformers;

[0055] Step 102, converting the 93 PDF versions of the power transformer technical standards into text through OCR and performing manual proofreading;

[0056] Step 103, parsing the clauses of the proofread WORD version of the power transformer technical standard;

[0057] Specifically, the technical standards are broken down into JSON format according to the four levels of [Chapter], [Clause], [Parameter], and [Content];

[0058] Step 104, establishing a hierarchical technical point system for power transformers based on knowledge graph technology;

[0059] Specifically, the equipment is divided into three levels: [equipment], [component], and [sub-component]. The knowledge graph technology is used to associate the third level [parameter] formed by 103 with the third level [sub-component] of 104. In this way, the specific technical requirements of the sub-components of each equipment can be matched together.

[0060] Step 105: query the differentiated nodes of the key points of the power transformer technical standard based on SPARQL.

[0061] Specifically, through the knowledge graph query language, by combining [equipment] or [component] or [sub-component] and [parameter], all technical requirements for a certain [parameter] of a certain [equipment] or [component] or [sub-component] can be found.

[0062] In one embodiment of the present invention, the specific implementation is as follows:

[0063] Step 101, collect and organize 93 technical standards covering power transformers.

[0064] Specifically, first, 93 electronic versions of power transformer technical standards (formats including but not limited to PDF, ODF, etc.) were collected through purchasing technical standard publications, online downloads and other channels. The specific list is shown in Table 1 List of Power Transformer Technical Standards; secondly, the non-PDF version of the technical standards was converted into a PDF version file through format conversion. Note that PDF files cannot be encrypted and editing cannot be restricted.

[0065] Table 1 List of technical standards for power transformers

[0066]

[0067]

[0068]

[0069]

[0070] Step 102, converting the 93 PDF versions of the power transformer technical standards into text through OCR and manually proofreading, and naming the proofread files as "serial number + standard number + standard release year + standard Chinese name.pdf";

[0071] Specifically, first, convert the PDF versions of the technical standards for power transformers into Word files one by one through open source OCR tools such as easyOCR and PaddleOCR, and add non-text content such as tables and pictures to the Word files by taking screenshots. The file content should include the standard cover, directory, main text, appendix, clause description, etc., and the file name is "serial number + standard number + standard release year + standard Chinese name.docx"; secondly, divide the 9 personnel into 3 groups (Group A, Group B, and Group C), and check the Word version of the technical standards with serial numbers 1-30, 31-60, and 61-93 in Table 1 word by word based on the PDF version, and modify the encoding, format, errors and other problems automatically converted by OCR; finally, conduct two cross-checks. The first time, Group A checks Group B, Group B checks Group C, and Group C checks Group A for technical standard verification. The second time, Group A checks Group C, Group B checks Group A, and Group C checks Group B for technical standard verification. The problems found are recorded and rectified to ensure the accuracy of the Word version of the technical standards.

[0072] Step 103, parsing the clauses of the proofread WORD version of the power transformer technical standard;

[0073] Specifically, first, the parsed files of the unstructured PDF and Word documents of each technical standard need to correspond to a folder named with the standard Chinese name, including 1 root file and 3 subfolders. One of the root files is a parsed json format file, named in the format of "standard number + '' + standard Chinese name.docx" and "standard number + '' + standard Chinese name.json", and the json format is shown in Table 2. The 3 subfolders include: figures, formula and source. The figure folder is used to store pictures of various figures and complex tables in the technical standard; the formula folder is used to store formula pictures; the source folder is used to store the original technical standard Word file and PDF, and the naming format is "standard number + '' + standard Chinese name.pdf (docx)". Secondly, the preface, introduction, table of contents, compilation instructions, chapters, appendices, references and other parts of the technical standard are defined as clauses. The clauses should contain four metadata items: clause number, clause title, clause level, and clause content. The clause content refers to the main text content under this clause, and does not include the title of the subordinate clause of this clause and the content of the subordinate clause title.

[0074]

[0075]

[0076] Step 104, establishing a hierarchical technical point system for power transformers based on knowledge graph technology;

[0077] Specifically, first, organize the two-level component system of the power transformer to form a standard list of transformer components. The first level is the main components of the transformer, such as the oil tank, bushing, tap changer, oil storage cabinet, grounding device, neutral point, etc. The second level is the sub-components of the main components of the transformer, such as the upper porcelain sleeve of the bushing, the insulating basin, the lower porcelain sleeve, the general cap, the oil storage cabinet, etc. Secondly, organize the technical points of the transformer for each component of the power transformer, including testing requirements, operation and maintenance requirements, installation requirements, acceptance requirements, maintenance requirements, etc., and use the name of the technical standard, clauses and other information as attributes. Finally, based on the knowledge graph technology, establish a power transformer triple to associate the technical points with each transformer component, such as Figure 2 shown.

[0078] Step 105: query the differentiated nodes of the key points of the power transformer technical standard based on SPARQL.

[0079] Specifically, a SPARQL query statement is written according to the component type or technical key points to be queried, and then the search is performed, for example, to query the key points of differentiation between different standards.

[0080] PREFIX ex:<http: / / example.org / >

[0081] SELECT? standardName? scope? differentiationPoint

[0082] WHERE{

[0083] ? standard ex:name? standardName;

[0084] ex:scope?scope;

[0085] ex:differentiationPoint? differentiationPoint.

[0086] }

[0087] Therefore, the differentiated comparison method of power transformer technical standards based on knowledge graph proposed in the present invention will effectively improve the efficiency and effect of differentiated comparison of power transformer technical standards, and can realize the retrieval and comparison of differentiated technical points of power transformer technical standards in real time and quickly, which greatly saves the time of expert differentiated comparison and lays the foundation for improving technical standards to guide transformer operation and maintenance and testing.
