[0002] Key processes are important links in the production process, and their stability and efficiency directly affect product quality and delivery cycle. Under the traditional method, the control of key processes adopts the method of paper-based process records and manual control, and there are mainly the following problems:

[0003] (1) The manufacturing process records of key processes at the production site are not electronic and structured. Operational process data (resources such as actual labor, tooling, equipment used, and actual process parameters adopted), self-inspection records, special inspection records, equipment operation records, etc. all adopt the method of paper-based records, and cannot realize the electronic storage, transmission, visual query and traceability of manufacturing process record data.

[0004] (2) The process record data is not standardized and unified. Different process specialties, different products, and different departments adopt different types of key process record forms, resulting in non-standardized and non-unified process record data.

[0005] (3) The production process control still adopts the method of manual offline control. For example: by manually querying the personnel, equipment and tooling requirements in the paper-based key process three-fixed table for task dispatching, equipment and tooling selection, there are problems of low efficiency and easy omission.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] An embodiment of the present invention provides a key process digital control system. The key process digital control system of the embodiment of the present invention is as Figure 1 shown, and realizes key process digital control based on a process data model. The construction of the process data model includes classifying key process data, and standardizing, structuring, and visualizing the process data to achieve efficient collection, storage, application, and management of the process data.

[0027] Classification of key process data:

[0028] The process data of key processes are classified into product - related data, process - related data, knowledge - related data, production - related data, etc. Product - related data mainly refers to the data inherited from design, including product name, product drawing number, product model, material data, design version, etc.; Process - related data is the data generated during the process design, including the process data in the key process operation content table (process document number, process number, process content, work step content, inspection content, etc.), the process data in the key process quality control table (technical conditions and key controlled content, equipment accuracy requirements, requirements for personnel, etc.), the process data in the key process inspection record table (inspection basis, key characteristic record requirements, etc.); Knowledge - related data refers to the induction and refinement of various technical knowledge, process templates, equipment resources, etc. to form a standard knowledge base for use in the process design process, thereby accelerating the process design progress and improving the consistency and standardization of process design; Production - related data refers to the data generated during the production execution process, such as operation results, inspection results, key process three - determination tables, etc.

[0029] Standardization of process data for key processes:

[0030] The standardization of process data can improve the standardization and reuse degree of process data. The most core work in the standardization of process data for key processes is the formulation of standard templates for various types of tables. Specifically, standardize the key process quality control data into the template of the key process quality control table, such as Figure 2 the key process quality control card shown, standardize the key process inspection record data of multiple specialties and types into the template of the key process inspection record table, such as Figure 3 the key process inspection record card shown, standardize the three - determination table into the key process three - determination table template as shown in Figure 4 where the purpose of the three - determination table is to specify the process method (process document), personnel, and equipment.

[0031] Structuring of process data for key processes:

[0032] Structured process data refers to the data scattered in various process documents during the traditional process, which are sorted and classified through certain rules and standards to form a data set with a clear structure and easy to be processed and utilized by computers. Structured process data enables process data to achieve effective sharing and rapid transmission among core operations such as design, manufacturing, and inspection, supporting digital transformation and intelligent manufacturing. The main implementation methods of structured process data for key processes are as follows:

[0033] (1) Tabular structuring: The data is organized in the form of a table. Each table consists of rows and columns. Each row represents a data record, and each column represents a specific attribute. The key process quality control table, key process inspection record table, and production process operation results and inspection results in process - related data adopt the tabular structuring method.

[0034] (2) XML Structuring: XML (eXtensible Markup Language) is a markup language used for storing and transmitting data. It uses a tree-like structure to organize data, and each node represents a part of the data. The operation content in product data and process data adopts the XML structuring method.

[0035] (3) Graph Structuring: A data structuring method based on graphs, where nodes represent entities and edges represent the relationships between entities. The visual process flowcharts and the flowcharts in approval flows adopt the graph structuring method.

[0036] (4) Database Structuring: In a relational database, the relationship between tables and fields is used to structure and store data. Knowledge data adopts this method and is displayed as structured process knowledge on the page.

[0037] Visualization of Process Data for Key Processes:

[0038] Integrate process data into digital platforms such as process planning systems and manufacturing execution systems to form structured and visual data, and encode various types of process data for easy data management and retrieval. In the information system, through functions such as data visualization and report generation, the scattered data can be collected and typeset according to preset templates to form visual files, helping process engineers, operators, and inspectors quickly understand the production status, evaluate production performance, and make scientific decisions.

[0039] Build the digital control system for key processes of the embodiment of the present invention based on the process data model. As Figure 1 shown, the digital control system for key processes of the embodiment of the present invention includes a process planning system, a product data management system, and a manufacturing execution system.

[0040] The process planning system is used to complete the compilation of structured process files and identify key processes according to the product data provided by the product data management system and the knowledge data from the process knowledge base. Among them, the structured process files contain structured process data, and the process data is recorded in the key process operation content table, the key process quality control table, and the key process inspection record table.

[0041] The product data management system is used to provide product data for the process planning system and receive the structured process data from the process planning system, and archive and send the structured process data to the manufacturing execution system in the form of XML text. In addition to the process files in XML format, the product data management system can also manage the engineering bill of materials (EBOM), the process bill of materials (PBOM), the production process record form, the process technical status, etc.

[0042] The manufacturing execution system receives and parses process data in the form of XML text, determines whether a key process exists based on the key process identifier, and parses the key process operation content table, key process quality control table and key process inspection record table to create a structured three-determination table, fills in the production process operation results and test results in the key process inspection record table, and generates a visual record table, wherein the three-determination table specifies the process method, personnel and equipment.

[0043] An embodiment of the present invention also provides a method for digital control of key processes based on a process data model, which utilizes the above-mentioned digital control system for key processes to execute a full-link digital control workflow of key processes including process design, process archiving and distribution, formulation of three fixed tables, task division, operation process recording, and inspection process recording, which specifically includes the following steps.

[0044] (1) Preparation of structured process documents for key processes. The process planning system is used to prepare structured process documents, including key process operation content tables, key process quality control tables, key process inspection record tables, etc., and key process labels are made. All process data are structured.

[0045] (2) Archiving of key process structured process files. The process data in the key process structured process files are archived in the product data management system in the form of XML text.

[0046] (3) Issuance of structured process documents for key processes. The process data in the structured process documents for key processes are issued to the manufacturing execution system in the form of XML text along with the production order.

[0047] (4) The manufacturing execution system receives the structured process data in the production order. The manufacturing execution system parses the XML text process data in the production order, determines whether there is a key process in the associated process based on the key process identifier, parses the process operation content, key process quality control table, key process inspection record table, etc., and issues a task to create a structured three-determination table.

[0048] (5) Create a structured three-determination table (determination of personnel, equipment, and process methods). Information such as product name, drawing number, equipment name, and tooling name are parsed and automatically generated from the structured process file. Equipment can be selected from the resource library, and operators and inspectors can be selected from the user list to complete the structured filling of the three-determination table.

[0049] (6) Assign work according to the personnel in the published three-fixed table. The manufacturing execution system automatically assigns work according to the operators and inspectors specified in the three-fixed table. Before assigning key process tasks, the three-fixed table for key processes must be published, otherwise the production cannot be started.

[0050] (7) Complete the process operations and fill in the operation records and self-inspection records in the Structured Key Process Inspection Record Form. The operator performs the process operations according to the operation requirements of the process document, and both the operating equipment and tooling need to be selected from the equipment list in the Three-Fixed Table.

[0051] (8) Complete the process inspection and fill in the special inspection records in the Structured Key Process Inspection Record Form. The inspector performs the inspection operations according to the inspection requirements of the process document, and both the inspection equipment and tooling need to be selected from the equipment list in the Three-Fixed Table.

[0052] (9) Typeset the key process record data according to the preset template to form a visual key process inspection record form, which is used as the content of the product quality data package.

[0053] Based on the process of the key process digital control method and the information architecture of the key process digital control system in the above embodiments of the present invention, by sorting out the flow route and corresponding relationship of process data in each system, the standard format and protocol for data exchange can be formulated to realize the generation, transmission and application of process data in different systems.

[0054] If a key process is involved, the process planning system will mark the words "key process" on the process document, and there is a "key process" identifier (such as "GZ=yes") on the corresponding xml file. The manufacturing execution system can identify the key process through the identifier on the xml file.

[0055] The Three-Fixed Table created by the manufacturing execution system inherits the data in the key process inspection record form of the process planning system. The product name, product drawing number, process document name, process document number, key process name, key process number in the Three-Fixed Table correspond to the corresponding information in the key process inspection record form. In addition, the "name and model specifications of the equipment used" in the Three-Fixed Table corresponds to the "equipment, instruments, measuring tools, tooling requirements" in the key process inspection record form. The manufacturing execution system fills in the "equipment, instrument, measuring tool, tooling number" (the equipment number can only be selected from the equipment specified in the Three-Fixed Table) and the recorded values of key characteristics in the key process inspection record card. After the manufacturing execution system completes the filling in the key process inspection record form, it visualizes and browses to generate the key process inspection record form and the Three-Fixed Table according to the standard style.

[0056] In summary, the key process digital control system and method of the present invention realize the structured storage, electronic recording, visual query, traceability and real-time sharing of key process process data through the construction of the key process process data model, the design of the key process digital control implementation process, and the construction of the key process digital control system, so as to realize the digital control of key processes for process design, manufacturing execution, and inspection processes, and meet the requirements of scientific research and production for digital control of the manufacturing process.

[0057] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
