[0049] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0050] For easier understanding, please refer to Figure 1 The embodiments of the test item testing methods based on CNAS testing laboratories provided in this application include:

[0051] Step 101: Use web crawling technology to capture the web pages of testing and standard laboratories on the resource platform in real time, and obtain the list of CNAS standard test items. The list of CNAS standard test items includes standard test items, text content and web page title.

[0052] Further, step 101 includes:

[0053] The web crawler technology is used to capture the web pages of testing and standard laboratories on the resource platform in real time to obtain the initial CNAS web page, which includes the initial title and initial content.

[0054] Based on title matching degree and content difference degree, the initial title and initial content are redundancy-filtered according to title keywords and content attributes respectively to obtain the web page title and text content;

[0055] Construct a list of CNAS standard test items based on the standard test items, page title, and text content in the initial CNAS webpage.

[0056] It should be noted that CNAS specifically tests the following items: accredited laboratory key locations, accredited authorized signatories and fields, accredited testing capabilities, accredited "Energy Star" testing capabilities, accredited calibration and measurement capabilities, and accredited laboratory judgment criteria.

[0057] Using web crawling technology, the web pages of accredited testing and calibration laboratories and accredited inspection bodies under the China Proficiency Testing Resource Platform were used as the starting point. Then, a traversal web content extraction was performed according to the crawling framework. Initially, the web page title, subtitles, tags, text content within tags, document information, images, and tables were extracted. The extracted title, subtitles, text content, and document information were used as feature information to be processed.

[0058] It should be noted that the web crawling technology used in this embodiment for traversal web content extraction means that the content of the title page and the pages contained in the subheadings under the title of the current webpage must be extracted; the main content information includes the webpage content summary, metadata description information, text description of the webpage content, keywords and other relevant main content information; the webpage document information refers to the documents in the current webpage in formats such as pdf, doc, excel, etc., which include the document type, name, size, creation time, modification time, crawling time and other relevant attribute information.

[0059] To ensure the completeness of the crawled information, the above traversal crawling operation is often performed multiple times. In order to reduce the redundancy of the crawled information, this embodiment needs to perform a redundancy filtering operation on the crawled information. This mainly involves analyzing the similarity or similarity of the title and text content based on the title matching degree and content difference degree, and merging or normalizing the two types of information with high similarity, thereby improving the accuracy and reliability of the information.

[0060] Initial CNAS webpage-related information was obtained by extracting content from web pages using web crawling technology. , ,in, This indicates the title information of the webpage; These represent the subheading information of the webpage, which together serve as the initial title; This indicates the main content of the webpage; The webpage document information represents the webpage and together they form the initial content.

[0061] First, we can define the set of titles crawled from the webpage content as follows: ,in, The number of page titles. Indicates the first The first heading defines the page content. The set of subheadings under each heading is ,in, For the first The number of subheadings under each heading. Indicates the first The first subheading defines the first element crawled from the webpage content. The first in the title The collection of webpage content under each subheading is ,in, The number of content elements in the main body of the webpage. No. The first title The first under each subheading Each webpage content element.

[0062] Secondly, TF-IDF technology crawls the set of titles from web page content. Extract keywords from each title element to obtain the corresponding keyword set. ,in, The number of keywords in each title.

[0063] After deleting and integrating all child elements in the keyword set, the set of all keywords in the title crawled from the webpage content is obtained. Where n represents the total number of keywords, Let represent the nth keyword. For the keyword set, calculate the keyword match between the first and second titles:

[0064]

[0065] in, The i-th keyword in the first subset of the keyword set and The j-th keyword The relevance, i.e. the matching degree; and:

[0066]

[0067] in, This represents the path length between the two keywords in the semantic primitive hierarchy. It is an adjustable parameter; Represents the calculation of keyword set The relevance of the keywords in the first subset to the keyword elements in the keyword set KW is greater than 1%. The position, that is:

[0068]

[0069] in, express Each keyword in the text has a relevance greater than KW. The number of keywords, the relevance of keywords in the second subset to keywords in the keyword set KW is greater than 100%. The position, that is:

[0070]

[0071] Among them, it means express Each keyword in the text has a relevance greater than KW. The number of keywords indicates a higher relevance than The number of keywords.

[0072] Normalizing the calculated title matching score yields a range. Title matching degree, for setting a threshold If the title matches If the two headings are similar or identical, they can be combined into one. If the two headings are inconsistent, they are two independent headings.

[0073] Next, the web page document in the initial content... Perform the following processing:

[0074] The set of document content under the n2nd subheading of the n1st heading obtained from the webpage content is: Where m represents the total number of documents on the page. This represents the m-th document, which contains information such as document type, name, size, creation time, modification time, crawling time, and other relevant attributes. VBA technology is used to retrieve all information attributes of each document in the document content set, resulting in an attribute information set.

[0075]

[0076] in, This represents all attributes contained in the m-th document. This represents the number of information attributes in the m documents within the document content set. (Calculation and...) and The difference score is used to represent the similarity between two documents. Its value ranges from 0 to 1. When the difference score is 1, it means the two documents are completely different. The smaller the difference score, the closer the two documents are. The specific process is as follows:

[0077] The document attributes of the two documents include type, name, size, creation time, modification time, crawling time, and other relevant attribute information;

[0078] The two documents are judged based on the type attribute in the extracted attribute information set. If the two documents have different type attributes, the difference between the two documents is 1, and the judgment process ends.

[0079] If the two documents are of the same type, they are distinguished based on the name attribute in the extracted attribute information set. The matching degree calculation method for webpage titles in this embodiment is used to compare the name attributes of the two documents to obtain the matching degree (Match). If the two documents match perfectly in terms of name attributes, the difference between them is 1, and the discrimination process ends.

[0080] If the calculated matching degree If the document names do not match completely, it indicates that the two documents' attributes do not match. Therefore, a determination is made based on the size, creation time, modification time, and crawling time from the extracted attribute information set. If {size} =size & Creation Time =Creation Time &Modified Time =Modified Time If}=1, it means the difference between the two documents is 1, and the discrimination process ends;

[0081] If {size =size & Creation Time =Creation Time &Modified Time =Modified Time If}≠1, then the comparison of the content of the two documents is used for judgment. Specifically, the content of the two documents is first automatically identified and extracted, and keywords are extracted from the extracted content. The keyword matching degree of the two documents is calculated using the webpage title matching degree calculation method in this embodiment. If If the content of the two documents is completely inconsistent, the comparison process will end. If they are consistent, the comparison will end. If they are inconsistent, the comparison will end. If they are inconsistent, the comparison will end. If they are inconsistent, the comparison will end. If they are completely inconsistent, the comparison will end.

[0082] Based on the above operations, a CNAS standard test item list is generated for subsequent comparison and verification, enabling the testing of test items in the local laboratory. The accuracy and completeness of the crawled data further ensure the reliability of the CNAS standard test item list; therefore, the verification results based on this list are more stable and reliable.

[0083] Step 102: Compare and calculate the current test items of the local laboratory with the CNAS standard test item list to obtain the comparison matching degree and parameter difference.

[0084] Further, step 102 includes:

[0085] Extract the text content and parameters to be compared from the current test items of the local laboratory and the list of CNAS standard test items, respectively;

[0086] The comparison matching degree is calculated based on the content of the text to be compared, and the parameter difference is calculated based on the parameters to be compared.

[0087] The text content to be compared and the comparison parameters extracted from the current test item and the CNAS standard test item list can be expressed as follows:

[0088]

[0089] Where M is the set of CNAS test items crawled, and , The total number of categories in the test item set. For the first A subset of class test items, and Let s be the s-th test item in the subset of test items of type k. Let B be the set of all test items in the local laboratory. ,in, ; , These represent the text content extracted from the CNAS test item set and the local laboratory test items, respectively. W is the preset weight of each test item in the detection process, and O is the set of preset standard intervals. To compare or verify the result values.

[0090] Comparing text content allows us to calculate the degree of relevance between the content, i.e., the comparison matching degree; comparing parameters allows us to calculate the difference between the two parameters, i.e., the parameter difference.

[0091] Step 103: Compare the verification results calculated based on the comparison matching degree, parameter difference and preset weight with the preset standard interval range to obtain the laboratory verification results.

[0092] Based on the above calculation results, the verification results can be calculated using preset weights:

[0093]

[0094] in, For test item categories, This represents the test items under each category, for example This indicates the first item in the CNAS test item set. The y-th test item in the category, The first one extracted from the test items of the local laboratory The y-th text content in the category; , , The weighting ratio of the test items. This indicates the text content matching degree of the corresponding test item. This represents the parameter difference for the corresponding test item. For the interval range of the corresponding test item, if:

[0095]

[0096] The calculation results are located at If the result falls within the specified range, it indicates that the local laboratory test item meets the requirements; otherwise, it does not.

[0097] In addition, the ability to calculate local test items can be calculated based on the calculated verification results:

[0098]

[0099] The capability calculation for the test item under the xth category of the laboratory is as follows:

[0100]

[0101] The capability calculation for all laboratory test items is as follows:

[0102]

[0103] Furthermore, step 103, followed by:

[0104] The current test item and special test items with a matching degree less than the matching threshold are compared twice to obtain the defect detection results.

[0105] It should be noted that, to avoid omissions or false positives during the testing process, this embodiment can perform a second comparison and verification test on certain special test items, such as those with low matching scores that have already been tested, omissions from the local laboratory, or the latest updated test items from the local laboratory. The comparison and verification process is as described above and will not be repeated here. The matching threshold can be set according to the actual situation, as long as it is reasonable, and is not limited here.

[0106] This embodiment uses a gap-filling approach to test all test items in the local laboratory one by one, and can also obtain the capability values ​​of the test items, which can meet the various needs of the current test item testing, and can produce results in a timely manner, ensuring testing efficiency.

[0107] This application provides a system that applies the method of this embodiment. Please refer to [link / reference needed]. Figure 3The system includes a crawling module 10, a splitting module 20, a comparison module 30, and a leak detection module 40. First, the crawling module crawls the web pages of testing and calibration laboratories on the China Proficiency Testing Resource Platform to obtain the latest test items for testing laboratories listed in CNAS. Then, the splitting module splits the obtained test items to obtain a classification list. Next, the comparison module compares all test items in the laboratory system locally with the latest test item classification list to analyze whether the testing laboratory meets the CNAS-based testing requirements and obtains the matching degree between the test items and the testing requirements. Finally, the leak detection module re-compares the test items with low matching degrees, missed test items, and real-time updated test items from the comparison module, realizing CNAS-based testing of the laboratory and further verifying the laboratory's capabilities.

[0108] Furthermore, the testing items for high-voltage switches and DC power supplies within the CNAS-accredited testing capabilities specifically include: high-voltage electrical appliances: AC voltage testing, lightning impulse voltage testing, partial discharge measurement, enclosure protection rating (IP code), electrical equipment enclosure protection rating against external mechanical impact (IK code), low temperature and high temperature testing; high-voltage AC circuit breakers and their components: all parameters; high-voltage AC load switches: all parameters; high-voltage disconnect switches and grounding switches: all parameters; etc. Each item / parameter includes relevant documents for the corresponding testing methods / standards.

Then, the laboratory capability is verified according to a preset standard range. While ensuring the reliability of the CNAS testing laboratory benchmark, the method of directly comparing and verifying each test item can also obtain verification results quickly, shortening the testing time cycle and ensuring the accuracy of the test results to a certain extent.
