[0036] It should be noted that the product quality data analysis unit 12 analyzes the product quality data by comparing the product quality data with the standard data. When the product quality data is within the range of the standard data, it is determined that the current product has no quality problems. When part of the product quality data is outside the range of the standard data, it is determined that the current product has quality problems. The product quality classification unit 13 obtains the quality problem item data of the product with quality problems, that is, the specific quality problem, by analyzing the part of the quality data of the product with quality problems that is outside the range of the standard data.

[0037] The quality problem classification module 22 is used to analyze the project data of the quality problems obtained in the product quality judgment module 1 and classify the quality problems of the products;

[0038] Specifically, the quality problem grading module 22 includes a comprehensive analysis unit 21 and a quality problem evaluation unit 22. The comprehensive analysis unit 21 is used to analyze the project data of the quality problems obtained by the product quality judgment module 1 to determine the impact of the current quality problems on subsequent production. The quality problem evaluation unit 22 is used to grade the quality problems of the current product according to the impact of the quality problems on subsequent production.

[0039] It should be noted that the quality problem evaluation unit 22 is classified into the following levels: Level 1: general quality problems, which have no impact on subsequent production and use; Level 2: quality issues of concern, which need to be resolved before going offline; Level 3: key quality issues, which have an impact on subsequent production and cannot pass the quality gate.

[0040] The multi-level authority management module 3 is used to preset the authority levels, and trigger the authorization confirmation request to the authorization module 4 according to the classification of the product quality problems by the quality problem classification module 22;

[0041] Specifically, the multi-level authority management module 3 includes an authority level setting unit 31, a first-level authorization unit 32, a second-level authorization unit 33 and a third-level authorization unit 34. The authority level setting unit 31 is used to preset the level of authorization required by the authorized personnel according to the level of different product quality problems obtained by the quality problem grading module 22. The first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 are used to preset the information of the authorized personnel. The information of the authorized personnel preset in the first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 includes card information and facial information. The first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 are used to obtain the level of product quality problems according to the quality problem grading module 22, trigger the authorization confirmation request to the authorization module 4, and the authority The level of authorization required by the authorized personnel preset in the level setting unit 31 is divided into three levels. The information of the authorized personnel preset in the first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 is used to determine the level of authorization of the authorized personnel set according to the authority level setting unit 31. If the level of authorization required by the authorized personnel preset in the authority level setting unit 31 is level one, only the information of the authorized personnel in the first-level authorization unit 32 is set. If the level of authorization required by the authorized personnel preset in the authority level setting unit 31 is level two, the information of the authorized personnel in the first-level authorization unit 32 and the second-level authorization unit 33 is set. If the level of authorization required by the authorized personnel preset in the authority level setting unit 31 is level three, the information of the authorized personnel in the first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 is set.

[0042] It can be understood that the authority level setting unit 31 presets different levels of authorization required by authorized personnel according to the grading of different product quality problems obtained by the quality problem grading module 22, and sets different numbers of information of authorized personnel in the first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 according to the different levels of authorization required by authorized personnel. For example, the specific quality problems of the products with quality problems currently produced are data unqualified and data missing. The data unqualified is graded as level two, and the data missing is graded as level three. The data unqualified triggers the corresponding setting of the first-level authorization unit 32 and the second-level authorization unit 33, and the first-level authorization unit 32 and the second-level authorization unit 33 respectively send authorization confirmation requests to the authorization module 4 for authorization confirmation by the authorized personnel; the data missing triggers the corresponding setting of the first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34, and the first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34 respectively send authorization confirmation requests to the authorization module 4 for authorization confirmation by the authorized personnel.

[0043] It should be noted that different product quality issues correspond to different levels of authorization required by authorized personnel and the corresponding first-level authorization units 32, second-level authorization units 33 and third-level authorization units 34. Different product quality issues correspond to different levels of authorization required by authorized personnel and the corresponding first-level authorization units 32, second-level authorization units 33 and third-level authorization units 34 are all different.

[0044] Authorization module 4, used to send an authorization confirmation request according to the multi-level authority management module 3, and complete the authorization after verifying the identity of the corresponding authorizer;

[0045] Specifically, the authorization module 4 includes a card reader 41, a camera 42, a card information recognition unit 43, a face recognition unit 44 and an authorization unit 45. The card reader 41 is used to read the card information of the authorized person, the camera 42 is used to obtain the facial information of the authorized person, the card information recognition unit 43 is used to identify and confirm the information of the authorized person's card according to the preset data in the multi-level authority management module 3, the face recognition unit 44 is used to identify and confirm the facial information of the authorized person according to the preset data in the multi-level authority management module 3, and the authorization unit 45 is used to confirm the authorization confirmation request according to the recognition results of the card information recognition unit 43 and the face recognition unit 44.

[0046] It can be understood that after receiving the authorization confirmation request sent by the multi-level permission management module 3, the authorized personnel first confirms the quality issues of the product. After confirmation, the corresponding authorized personnel collect the card information and facial information of the corresponding authorized personnel through the card reader 41 and the camera 42, and identify them with the corresponding first-level authorization unit 32, the second-level authorization unit 33 and the third-level authorization unit 34. The preset card information and facial information are identified. After the identification is passed, the current product is authorized and confirmed. After the confirmation is completed, the products with the first-level quality problem are released to the next production process. The products with the second-level quality problem need to deal with the quality problem before entering the next production process and then be released to the next production process. The products with the third-level quality problem need to be processed offline.

[0047] As a preferred embodiment, facial information is also used to identify the mental state of the current authorized person. The mental state of the current authorized person is analyzed and evaluated. The evaluation is divided into level one, level two and level three. Level one is a good mental state, level two is a general mental state, and level three is a poor mental state. When the mental state of the current authorized person is judged to be level three, the current facial recognition result is failed. The mental state needs to be adjusted to level one or level two and the quality issues of the product need to be reconfirmed before it can be passed. This is used to avoid unclear confirmation of product quality issues and prevent products with quality issues from flowing into the next production process.

[0048] The present invention adopts a multi-level authority management method. After a problem with the quality of a product occurs, the quality problem of the product is graded. By presetting the number of levels of authorization required by authorized personnel according to different graded quality problems, the quality problem of the current product is authorized and confirmed by multi-level authorized personnel after a quality problem occurs, thereby achieving the effect of controlling the final quality of the product and solving the problem that products with quality problems in the current production line production process flow into the next production process.
