the user only needs to input the first standard of the textile product to be compared with the second standard of the textile product, the method realizes the automatic comparison of the standards of the textile product, and when the standard of the textile product is not input by the user, preset information is output to remind the user, for example: "the first standard input by you is not the standard of textile products and is not in the comparison range of the standard of the system"; and determining whether the standard input by the user is a textile standard, and mainly determining whether the standard object product is a product in a preset textile product library. For example, the first standard and the second standard are both standards of two enterprises of western style pants, the standards are firstly analyzed and extracted, and key indexes specified in the standards are determined; starting from key indexes, realizing the hierarchical comparison of standards; during extraction, extracting key indexes in advance based on all international standards and national standards of textile products, performing comprehensive analysis to determine the extracted key indexes possibly existing in the standards, constructing a key index extraction library, and performing rapid extraction of the key indexes according to the key index extraction library, wherein the key indexes comprise: washing size change rate, dry-cleaning size change rate, twist slope after dry cleaning, twist slope after water washing, fabric tearing strength and the like, and then performing template evaluation on the extracted key indexes to obtain evaluation values; the evaluation template is established in advance, and can be manually established by a user, for example, the tearing strength of the fabric is greater than or equal to 5N, and the corresponding evaluation value is 0; the tearing strength of the fabric is more than or equal to 10N, and the corresponding evaluation value is 100; the tearing strength of the fabric is more than or equal to 100N, and the corresponding score value is 110; the tearing strength of the fabric is more than or equal to 200N, and the corresponding score value is 120; can also be obtained according to big data analysis; the big data analysis mainly includes obtaining a key index and a large amount of corresponding detection data, determining based on a distance between a center of distribution of the large amount of detection data and a center of the key index, and defining a corresponding score value by the distance, for example: a water washing size change rate of-0.8 to 0.8 at the center thereof being zero, a water washing size change rate of-0.9 to 0.7 at the center thereof being-0.1 at the second standard, and a deviation of the large amount of detection data being-0.8 according to the large amount of detection data being-0.2, i.e., the range of data being 0.6 to-1.0; therefore, the score value of the key index of the corresponding first criterion is 75; the score value of the second criterion was 87.5. Evaluating each key index through a template, determining evaluation values of the standards by integrating evaluation values of all key indexes, comparing the two standards through the height ratio of the evaluation values, and comparing each key index independently; furthermore, the relevance between the key index of the first standard and the key index of the second standard can be determined, relevance comparison is realized, and relevance analysis is performed.

The standard comparison method of the textile products provided by the invention starts from the key indexes, realizes the evaluation of the standards based on the difference of the key indexes and the quantification of the key indexes, further realizes the objective evaluation between the two standards, provides a screening basis for the standards of enterprises by comparing the advantages and disadvantages of the two standards, and further provides guidance for the enterprises to make own standards.

In one embodiment, step S5: determining a first evaluation value of the first criterion or a second evaluation value of the second criterion based on the evaluation values, including:

determining the weight corresponding to the key index based on the key index;

determining a first evaluation value of the first criterion or a second evaluation value of the second criterion based on the weight corresponding to the key indicator and the evaluation value corresponding to the key indicator, wherein the calculation formula of the first evaluation value or the second evaluation value is as follows:

;

wherein the content of the first and second substances,is the first evaluation value or the second evaluation value;is the first standard or the second standardEach key index;is as followsThe weight corresponding to each key index;the number of key indexes in the first standard or the second standard.

The working principle and the beneficial effects of the technical scheme are as follows:

and respectively calculating the evaluation of each key index, determining the weight according to the importance degree of the key index to the standard, further determining the evaluation value corresponding to the standard, and realizing accurate standard evaluation by adopting a thinning and layering method. The weight corresponding to the key index is preset, and may be set by a user, for example, the weight corresponding to the washing size change rate is 0.2, the weight corresponding to the dry-cleaning size change rate is 0.2, the weight corresponding to the twist slope after dry-cleaning is 0.2, the weight corresponding to the twist slope after water-cleaning is 0.2, the weight corresponding to the fabric tearing strength is 0.4, the weight corresponding to the color difference is 1, or may be common agreement based on a plurality of enterprises, obtained from a big data platform, for example, the key index may be sent to a plurality of experts of the enterprises, the weights are distributed by the experts, and then weighted average is performed based on the authority limits of the experts to determine the final weight.

In one embodiment, at step S2: index item extraction is carried out on the first standard and the second standard respectively, and after a plurality of key indexes are obtained, the method further comprises the following steps:

step S21A: judging whether the first standard and the second standard are corresponding national standards and/or international standards;

step S22A: when the first standard is a national standard and/or an international standard and the second standard is not a national standard and/or an international standard, determining whether a key index of the second standard meets a key index of the first standard; outputting the conforming key indexes and the non-conforming key indexes;

step S23A: when the second standard is a national standard and/or an international standard and the first standard is not a national standard and/or an international standard, determining whether the key index of the first standard meets the key index of the second standard; outputting the conforming key indexes and the non-conforming key indexes;

step S24A: when the second standard is not the national standard and/or the international standard and the first standard is not the national standard and/or the international standard, the process proceeds to step S3,

step S25A: when the second standard is a national standard and/or an international standard and the first standard is a national standard and/or an international standard, outputting a preset first error message.

The working principle and the beneficial effects of the technical scheme are as follows:

when one of the two standards to be compared input by the user is the national standard or the international standard, only the other standard is required to be verified whether the other standard meets the national standard and/or the international standard. When one of the two standards to be compared is an international standard and the other is a national standard, a first error message is output, the first error message indicates which standard is the international standard and which standard is the national standard, but the comparison is not performed. Wherein, whether the judgment standard is the national standard or the international standard can be realized by three ways: the first and second keyword methods are used for extracting keywords of a first standard or a second standard, and when the keywords are matched with the keywords of the national standard or the international standard, the keywords are determined to be the national standard or the international standard; secondly, calculating the similarity between the standard and the text of the national standard or the international standard, and determining the standard as the national standard or the international standard when the similarity is greater than a preset threshold value; thirdly, by comparing the key indexes, when the key indexes are consistent with the international standard or the national standard, the key indexes are determined to be the national standard or the international standard, and the consistency is consistent from the aspects of the number of the key indexes, the content of the key indexes and the like. The first error message may be "both of the two standards input by you are national standards and/or international standards, and are not the standard comparison range of the system".

In one embodiment, at step S2: index item extraction is carried out on the first standard and the second standard respectively, and after a plurality of key indexes are obtained, the method further comprises the following steps:

step S21B: correlating the key indicators within the first criteria with the key indicators within the second criteria;

step S22B: counting the number of the associated key indexes, and calculating the association degree of the first standard and the second standard by the following formula,

；

wherein the content of the first and second substances,in order to be the degree of association,is the number of associated key indicators; a is the number of key indicators within the first criterion; b is the number of key indicators within the second criterion;

step S23B: and outputting preset second error information when the association degree is smaller than a preset association threshold value.

The working principle and the beneficial effects of the technical scheme are as follows:

in comparison, the correlation degree between the first standard and the second standard needs to be determined, that is, whether the first standard and the second standard are comparable or not needs to be determined, when the two standards are not directed to the same object or similar objects, the two standards do not need to be compared at all, and the correlation degree between the standards can be analyzed and calculated from the correlation of the key indexes to judge the correlation. The key indexes in the first standard are related to the key indexes in the second standard, and the same indexes are mainly related to similar indexes. When the vast majority of key indexes in the standards can be the same in one-to-one correspondence, the first standard and the second standard can be determined to have comparability, so that the two irrelevant standards are prevented from being compared, and the comparison accuracy is improved. In addition, the similarity between the first standard and the second standard can be calculated based on the extracted keywords, and the comparison is started when the similarity is greater than a preset similarity threshold. Wherein the association threshold may be set to 70%; the preset second error message is "the association between two criteria you input is not large, and there is no comparability, please determine whether it is the criteria of the same product". For example, key indicators of the first criterion include: washing size change rate, dry-cleaning size change rate, twist slope after dry-cleaning, twist slope after water washing, and fabric tearing strength; key indicators of the second criterion include: washing size change rate, dry-cleaning size change rate, twisting slope after dry-cleaning, twisting slope after water-cleaning, back seam joint strength and seam slippage; the correlation degree calculated by the embodiment is 80%; greater than 70% of the association threshold, an alignment between the two standards can be performed. For example, key indicators of the first criterion include: washing size change rate, dry-cleaning size change rate, twist slope after dry-cleaning, twist slope after water washing, and fabric tearing strength; key indicators of the second criterion include: washing size change rate, dry cleaning size change rate, back seam strength, seam combing and waistline; the correlation degree calculated by the embodiment is 40%; and if the correlation degree is less than 70 percent of the threshold value of the correlation degree, comparing the two standards, and outputting second error information.

In one embodiment, at step S2: index item extraction is carried out on the first standard and the second standard respectively, and after a plurality of key indexes are obtained, the method further comprises the following steps:

The key indexes in the first standard are related to the key indexes in the second standard, and the same indexes are mainly related to similar indexes. When the vast majority of key indexes in the standards can be the same in one-to-one correspondence, the first standard and the second standard can be determined to have comparability, so that the two irrelevant standards are prevented from being compared, and the comparison accuracy is improved. In addition, the similarity between the first standard and the second standard can be calculated based on the extracted keywords, and the comparison is started when the similarity is greater than a preset similarity threshold. Wherein the association threshold may be set to 70%; the preset second error message is "the association between two criteria you input is not large, and there is no comparability, please determine whether it is the criteria of the same product". For example, key indicators of the first criterion include: washing size change rate, dry-cleaning size change rate, twist slope after dry-cleaning, twist slope after water washing, and fabric tearing strength; key indicators of the second criterion include: washing size change rate, dry-cleaning size change rate, twisting slope after dry-cleaning, twisting slope after water-cleaning, back seam joint strength and seam slippage; the correlation degree calculated by the embodiment is 80%; greater than 70% of the association threshold, an alignment between the two standards can be performed. For example, key indicators of the first criterion include: washing size change rate, dry-cleaning size change rate, twist slope after dry-cleaning, twist slope after water washing, and fabric tearing strength; key indicators of the second criterion include: washing size change rate, dry cleaning size change rate, back seam strength, seam combing and waistline; the correlation degree calculated by the embodiment is 40%; and if the correlation degree is less than 70 percent of the threshold value of the correlation degree, comparing the two standards, and outputting second error information.
