[0066] The features and advantages of the present application will be further described in the following embodiments.

[0067] Embodiment One

[0068] Due to the characteristics of multi-variety and small batch of electronic equipment products, and the complex working environment, the individual conditions of the products to be repaired are complex and different, resulting in great difficulty in managing the repair process of the products; in the repair process of electronic equipment products, the recording and transmission of information, the control of materials, and the design of process procedures all depend on human activities, and a large amount of human and management costs are required to control the repair process. Moreover, the repair material information transmitted by manual transmission is inaccurate and lagging, resulting in an increase in time and material costs.

[0069] In the field of electronic equipment, the engineering bill of material (EBOM) of a product integrates the components, files and their relationships of the product together, directly guides the production and assembly process of the product, and gradually realizes the digitization and informatization of the production process of the product.

[0070] As a part of the whole life cycle management of a product, the repair process can also develop towards digitization and informatization based on the mode of bill of material; based on this, the embodiment provides a repair process control method, through the implementation of the method, the fine management of repair materials can be realized, the repair process information can be standardized and structured, and through the data processing mode, the applicable treatment measures are recommended according to the detection and identification results, the repair process procedures are generated, the repair process design of the process personnel is assisted, the performance of the repair process management is improved, and the costs required by the repair process are reduced.

[0071] Therefore, the embodiment aims at the above problems, and proposes an electronic equipment maintenance process control method based on product EBOM and a database, so as to realize fine management of maintenance materials, standardization and structuring of maintenance process information, recommend applicable processing measures according to the detection and identification results, generate maintenance process procedures, assist process personnel in maintenance process design, improve the performance of maintenance process management, and reduce the costs required in the maintenance process.

[0072] Referring to Figure 1 , the electronic equipment maintenance process control method based on product EBOM and a database specifically comprises the following steps:

[0073] Step S1: Establishing a maintenance feature database and a maintenance process database;

[0074] Step S2: Taking the detection and identification results of the product to be maintained as input, combining the maintenance feature database information, and outputting maintenance material requirements through data processing activity 1, and pushing to an ERP system, so as to realize fine management of maintenance materials;

[0075] Step S3: Taking the detection and identification results of the product to be maintained as input, combining the maintenance process database, outputting maintenance processing measures and initialized maintenance process procedures through data processing activity 2, pushing to an MES system, realizing guidance on the maintenance operation process, and finally achieving the purpose of controlling the maintenance process.

[0076] In the embodiment, specifically, the maintenance feature database is composed of maintenance feature elements;

[0077] The maintenance feature element contains four attributes, namely, “problem phenomenon”, “damage degree”, “processing intention”, and “processing method”;

[0078] The maintenance process database is composed of maintenance process elements; it should be noted that the maintenance process element is based on the maintenance knowledge of an organization, and details the “processing method” in the maintenance feature element, and reflects the sequence of maintenance processing and the requirements of man, machine, material, method, environment, and measurement;

[0079] The maintenance feature element contains three attributes, namely, “process”, “step”, and “action”.

[0080] In the embodiment, specifically, the specific definitions of the attributes are as follows:

[0081] The “problem phenomenon” defines the specific performance of the material problem; for example, the damaged coating film layer on the surface of the material, the scratch on the surface of the film layer is defined as “coating scratch”, and the local shedding of the film layer is defined as “coating local shedding”;

[0082] The "damage degree" defines the degree of a certain embodiment problem; the severity of the problem is defined as "mild", "moderate" and "severe" according to the maintenance experience of the organization; the "damage degree" is strongly correlated with the "problem phenomenon", for example, when the "problem phenomenon" is "coating scratch", the degree of the problem can be defined from two dimensions of scratch depth and scratch distribution: when the scratch has no scratch feeling and the distribution area is less than 5% of the overall area, it is defined as "mild"; when the scratch has no scratch feeling and the distribution area is greater than 5% of the overall area, or the scratch has scratch feeling and the distribution area is less than 5% of the overall area, it is defined as "moderate"; when the scratch has scratch feeling and the distribution area is greater than 5% of the overall area, it is defined as "severe". If the damage degree of a certain problem cannot be defined, the content can be empty;

[0083] The "treatment intention" defines the disposal method of the problem material; when the material problem can be solved by rework and repair, it is defined as "repairable", and when the material problem cannot be solved by rework and repair and must be replaced by new material, it is defined as "replacement";

[0084] The "treatment method" is defined as a specific treatment measure for the material problem, which is an embodiment of the maintenance knowledge of the organization, for example, when the coating film on the surface of the material is damaged, the treatment method can be defined as "surface local touch-up" or "grinding to remove the original film layer and re-spraying after cleaning", and the specific treatment method is matched with the "problem phenomenon" and "damage degree" attributes;

[0085] The "process" is defined according to the industry habits followed by the organization, representing the skilled personnel, site, equipment and facilities required to perform maintenance operations, such as "mechanical assembly" and "electrical assembly";

[0086] The "work step" is a decomposition and sequencing of all maintenance operations required to be completed in a certain process, which embodies the order and specific content of the operation;

[0087] The "action" is a decomposition and sequencing of a specific maintenance operation in a work step, which embodies the specific action of the maintenance operation.

[0088] In this embodiment, specifically, the data processing activity one takes the EBOM of the product as input and outputs the maintenance BOM of the product, including the following three steps:

[0089] Step S21: generating an initial maintenance BOM of the product;

[0090] Step S22: assigning values to the attributes of the initial maintenance BOM of the product;

[0091] Step S23: converting the initial maintenance BOM of the product into a maintenance BOM.

[0092] In this embodiment, specifically, the step S21 includes:

[0093] Copy the EBOM data of the product, and add five attributes to each node of the EBOM structure tree, which are "ownership level", "problem phenomenon", "damage degree", "treatment intention" and "treatment method";

[0094] Among them, the four attributes of "problem phenomenon", "damage degree", "treatment intention" and "treatment method" have the same attribute definition as the maintenance feature element.

[0095] In this embodiment, specifically, the step S22 comprises:

[0096] Step S221: Establish the association between the four newly added attributes of the product initial maintenance BOM, i.e. "problem phenomenon", "damage degree", "treatment intention" and "treatment method", and the maintenance feature database, and the attribute content can be directly extracted from the maintenance feature database;

[0097] Step S222: Through the detection and identification activities, the corresponding maintenance feature elements are screened out in the way of reading and screening the two attributes of "problem phenomenon" and "damage degree" of the maintenance feature database, and the contents of each attribute of the maintenance feature element are used to assign values to the four attributes of the initial maintenance BOM node, i.e. "problem phenomenon", "damage degree", "treatment intention" and "treatment method";

[0098] Step S223: After the assignment is completed, fill in the attribute content of "ownership level" of the product initial maintenance BOM according to the rules.

[0099] In this embodiment, specifically, the rules in the step S223 comprise:

[0100] The assigned BOM node is the node directly constituting the initial maintenance BOM structure tree, and the content of "ownership level" is filled in as "this level";

[0101] The assigned BOM node is the node indirectly constituting the initial maintenance BOM structure tree, and the content of "ownership level" is filled in as "child level".

[0102] In this embodiment, specifically, the step S23 comprises:

[0103] According to the attributes of the initial maintenance BOM node, modify the quantity attribute of the initial maintenance BOM representing the quantity of materials according to the rules;

[0104] After the change of the quantity of the initial maintenance BOM node is completed according to the rules, the maintenance BOM is outputted;

[0105] Among them, the rules include:

[0106] When the "treatment intention" attribute of the maintenance initial BOM node is "to be replaced", the attribute representing the number of nodes is maintained as the original value.

[0107] When the "treatment intention" attribute of the maintenance initial BOM node is "to be repaired" or not assigned, the attribute value representing the number of nodes is changed to 0.

[0108] In this embodiment, specifically, the data processing activity two is to generate a maintenance material requirement list and a maintenance process procedure based on the maintenance BOM, including the following two steps:

[0109] Step S31: generating a maintenance material requirement list.

[0110] Step S32: maintenance process procedure output.

[0111] In this embodiment, specifically, the step S31 includes:

[0112] Extracting the node information with the number of nodes attribute in the maintenance BOM being not 0 nodes, outputting the specifications and quantities of materials, and generating a "maintenance material requirement list"; it should be noted that this list is the materials required for the maintenance product, and the organization can prepare the materials based on it;

[0113] Step S32 includes:

[0114] Based on the content of the "treatment method" attribute of the maintenance BOM node, associating the corresponding maintenance process element in the maintenance process database, integrating and outputting the maintenance process element associated with the maintenance BOM as a maintenance process procedure;

[0115] The integration rule is as follows:

[0116] All the "belonging level" attributes of the maintenance BOM nodes are "this level", and the associated maintenance process elements are integrated into a maintenance process procedure and outputted;

[0117] The "belonging level" attribute of the maintenance BOM node is "child level", and the associated maintenance process element is outputted as a maintenance process procedure.

[0118] The process personnel can adjust the maintenance process procedure to generate a final product maintenance process to guide the product maintenance process.

[0119] Embodiment two

[0120] An electronic equipment maintenance process control method based on product EBOM and knowledge database driving, including a maintenance feature database, a maintenance process database, a data processing activity one, and a data processing activity two.

[0121] The maintenance feature database is composed of maintenance feature elements, and the attributes of the maintenance feature elements are as follows Figure 2 .

[0122] The maintenance process database consists of maintenance process elements, and the attributes of these maintenance process elements are as follows: Figure 3 .

[0123] Data processing activity consists of three steps, such as Figure 4 .

[0124] Data processing activity two consists of two steps, such as Figure 5 .

[0125] In this embodiment, the method is used to control the maintenance process of product A.

[0126] First, establish a maintenance feature database and a maintenance process database, and then establish the relationship between the feature elements of the two databases, such as... Figure 6 .

[0127] Copy the EBOM of product A, and add five maintenance attributes to the EBOM node: "Attribution Level," "Problem Description," "Damage Severity," "Handling Intent," and "Handling Method." This will convert the EBOM of product A into the initial maintenance BOM for product A. Figure 7 .

[0128] The four maintenance attributes of the initial maintenance BOM node, namely "problem phenomenon", "damage level", "handling intention" and "handling method", are associated with the maintenance feature database. The maintenance attribute content can be directly extracted from the maintenance feature database.

[0129] In this example, the detection and identification results of product A are as follows: First, there is a scratch on the outer surface of the box, and the scratch feels rough to the touch; second, the casing of the integrated chip on the power board is deformed.

[0130] Based on the results of these two tests and identifications, the maintenance attributes of the "box" and "integrated chip" nodes in the initial maintenance BOM of product A are assigned values.

[0131] like Figure 8 As shown, the process first involves reading and filtering the "problem phenomenon" and "damage level" attributes from the maintenance feature library to determine the correspondence between the "box" node and "maintenance feature element ②", and between the "integrated chip" node and "maintenance feature element ④". Then, the maintenance attributes of the "box" and "integrated chip" nodes in the initial maintenance BOM are assigned values ​​based on the attributes of "maintenance feature element ②" and "maintenance feature element ④". Following the rules, the "attribution level" of the maintenance attribute for the "box" is defined as "this level", and the "attribution level" of the maintenance attribute for the "integrated chip" is defined as "child level".

[0132] According to the rules, change the "Material Quantity" attribute of each node in the initial maintenance BOM of product A to transform the initial maintenance BOM of product A into a maintenance BOM.

[0133] As Figure 9 , the maintenance attribute of the node is "maintainable" or has no content, and the "material quantity" is defined as 0; the maintenance attribute of the node is "replaceable", and the "material quantity" remains unchanged.

[0134] Based on the maintenance BOM of product A, a "product A maintenance material requirement list" is generated, as Figure 10 , which is provided to the ERP system of the organization for the preparation of maintenance materials.

[0135] Based on the maintenance BOM of product A, two maintenance processes of product A are generated, as Figure 11 , which are provided to the process personnel of the organization and can be used to guide the maintenance process of product A after adjustment.

[0136] The maintenance process controlled by the method can not only finely manage the materials required for maintenance, which is conducive to improving the inventory management level of the enterprise, but also realize the output of knowledge-based process documents, reduce the workload of process personnel, and is conducive to cost reduction and efficiency improvement.

[0137] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the technical concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
