BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a diagram showing the supplier information encoding rules. DETAILED DESCRIPTION

[0015] The following is a detailed description of the implementation of the method. It should be emphasized that the following description is only exemplary and is not intended to limit the scope of the present invention and its application. Based on the information data in the process of verifying the supplier's qualification and capability information, and referring to normative reference documents such as national standards and industry standards, the specific implementation steps are as follows:

[0016] (1) Integrate data from multiple sources

[0017] Relying on data sources such as the ECP2.0 platform supplier information data, various material supplier qualification and capability verification information collection templates, etc., we comprehensively explore 75 types of power material and service supplier information data projects to ensure that the supplier information data projects not only fully reflect the current requirements for power grid supplier information management, but also proactively consider the needs of promoting the construction of a green, modern digital supply chain.

[0018] (2) Unified data classification

[0019] Based on the credit data items of each type of supplier, with reference to the State Grid Enterprise Standard "Q / GDW12280 Electric Power Material Supplier Information Classification Guidelines" Part 2 "General Information of Suppliers" and the enterprise standard submission for approval of the supplier-specific information classification guidelines for 38 types of key electric power materials completed from 2021 to 2022, the special information of 75 types of suppliers such as distribution terminals was extracted, and summarized according to the levels of categories, major categories, medium categories, and minor categories. Among them, the data dimensions at the category level include 10 categories, namely basic information of the enterprise, financial status, report certificates, product performance, R&D design, production and manufacturing, testing and inspection, raw material components, after-sales service, and product production capacity. Each category module level includes several major categories. Each major category contains a series of related supplier information data categories, which basically cover the information data that various suppliers will involve at present and in the future. Each middle category is further divided into subcategories to meet the need for multiple options in the middle category (for example, the voltage level middle category information data item includes 6kV, 10kV, 35kV, 110kV and other subcategories).

[0020] (3) Unified data names

[0021] In response to the problem of inconsistent and non-standardized data item names in different supplier information data sources, the project team, based on previous work experience, conducted a comprehensive and systematic review of the above 75 types of special information of power material and service suppliers, with more than 35,000 information data items. Based on the reference to relevant national standards, industry standards and other normative reference documents and other authoritative sources, the naming of special information data of various suppliers was unified to ensure that the large, medium and small categories of information data expressing the same meaning under different material categories and different category levels all have unified and standardized names.

[0022] (4) Unified data definition

[0023] Based on the keywords of the special information data of different categories of suppliers and the technical characteristics of the products of different material categories, we traced back and cited the relevant national standards, industry standards and other normative reference documents and other authoritative information sources one by one, and gave rigorous and standardized definitions to the special information data items of power material and service suppliers such as distribution terminals, ensuring the professionalism and universality of the standard document of the supplier information classification guidelines.

[0024] (5) Constructing data encoding

[0025] Based on the national standard "Basic Principles and Methods of Information Classification and Coding (GB / T 7027-2002)", and referring to the industry standards and local standards related to information data coding issued by organizations outside the system, from the perspective of information data value mining and data interaction of power materials and service suppliers, the rules for information data coding of power materials and service suppliers are studied and constructed. The specific representation is as follows Figure 1 As shown, the specific composition and meaning of each part of the code are as follows:

[0026] 1) The prefix identification code is an 8-digit mixed code of letters and numbers, which is used to uniquely identify the material category corresponding to the supplier information. The supplier information material category includes general information and special information for specific materials (such as transformers). General information applies to all materials, and special information applies only to specific materials. Among them:

[0027] ① There are no specific items under general information. The prefix identification code of basic information is "G0000001";

[0028] ② There are several detailed items under the special information, which correspond to the specific material names in the material master data. For example, under the special information of AC transformer suppliers, "G1001001" represents 6kV AC transformer. In the future, in the classification guidelines for special information of various suppliers, the material names in the material master data to which the classification guidelines for special information of suppliers apply can be marked.

[0029] 2) The category code consists of one letter, in alphabetical order, from A to J, representing the ten categories of supplier basic information, financial status, report certificate, product performance, R&D design, production and manufacturing, testing and inspection, raw material assembly, after-sales service, and product production capacity.

[0030] 3) The major category code consists of two digits and is coded in sequence from "01" according to the order of the major categories under each category dimension. The "other" major category is not allowed.

[0031] 4) The category code consists of 4 digits, where:

[0032] ① The middle categories in the supplier's general information are coded in the order of the middle categories under each major category, starting from "0001";

[0033] ② The categories in the dedicated information of each specific material or service supplier shall be coded in sequence starting from "1001" according to the order of the categories under each major category;

[0034] ③The “other” category is not allowed.

[0035] 5) The sub-category code consists of 3 digits, starting from "001" and coding in sequence. For the sub-category with the content of "other", it is represented by "999" to ensure the scalability of the coding.
