[0052] In some embodiments, the planning management subsystem includes a task book summary module and a scientific research and production planning module;

[0053] The task book summary module is used to obtain and output production contracts and development task books

[0054] The scientific research and production planning module is used to respond to the planners' operation of inputting production planning data based on production contracts and development task orders, and send production planning data to the product data management subsystem and procurement management subsystem.

[0055] Specifically, the planning management subsystem includes two modules: signing contracts / accepting research and development task orders, and scientific research and production planning.

[0056] The task order summary module is used to summarize the production-related contracts (contracts, official documents, others) and / or development task orders signed by various business departments.

[0057] The scientific research and production plan module is used to formally issue the enterprise's scientific research and production plan.

[0058] Optionally, the scientific research and production planning module can be set with compilation, review, and approval permissions, and different production planners' login accounts correspond to different permissions. For example, the login account of production planner A only has compilation permissions, and the login account of production planner B has compilation permissions and review permissions. He can review or modify the production plan data input into the scientific research and production planning module by production planner A, and can also compile production plan data and input it into the scientific research and production planning module; the login account of production planner C has compilation permissions, review permissions, and approval permissions. He can review or modify the production plan data input into the scientific research and production planning module by production planner A, and can also directly approve the production plan data reviewed by production planner B, and can also directly compile production plan data and input it into the scientific research and production planning module.

[0059] In some embodiments, the product data management subsystem includes a design and development module, a process management module, and an inspection and test planning module;

[0060] The design development module is used to respond to the operation of the designer inputting the design file data set based on the production plan data, maintain the design file data set, and send the design file data set to the process management module;

[0061] The process management module is used for maintaining the process file data set in response to the process personnel inputting the process file data set based on the design file data set, and sending the process file data set to the inspection and test planning module and the execution manufacturing subsystem;

[0062] The inspection and test planning module is used to respond to the inspection and test planner's operation of inputting the inspection and test file data set based on the process file data set, maintain the inspection and test file data set, and send the inspection and test file data set to the execution manufacturing subsystem.

[0063] Specifically, the Product Data Management (PDM) subsystem is used to manage all product-related information (including part information, configuration, documents, CAD files, structure, permission information, etc.) and all product-related processes (including process definition and management). By implementing PDM, production efficiency can be improved, which is conducive to the management of the entire life cycle of the product, strengthens the efficient use of documents, drawings, and data, and standardizes the work process.

[0064] The product data management system includes three modules: design and development module, process management module and inspection and test planning module. The documents released by PDM strictly implement the three-level review system (proofreading, review and approval).

[0065] The design and development module is used by the designers of the design department to log in to their own accounts. After accepting the development task book, it is used to start the design and development work, carry out design and development planning, create and maintain the product structure tree, compile and issue design documents (including drawings), etc., that is, to complete the operation of inputting the design file data set into the design and development module based on the production plan data, and maintain the design file data set;

[0066] The process management module is used by process personnel of the process department to log in to their own accounts. After receiving the design files, they start to compile and issue the process files and carry out process equipment design, etc., that is, they complete the input of the process file data set into the process management module based on the design file data set;

[0067] The inspection and test planning module is used by the inspection and test planners of the quality inspection department who log in to their own accounts. After receiving the process documents, they carry out inspection and test planning and prepare inspection records, etc., thus completing the input of the inspection and test file data set into the inspection and test planning module based on the process document data set.

[0068] In some embodiments, the procurement management subsystem includes a procurement planning module and a procurement module;

[0069] The purchasing plan module is used to respond to the operation of the material planner inputting the purchasing plan data based on the production plan data, maintain the purchasing plan data, and send the purchasing plan data to the purchasing module;

[0070] The procurement module is used to respond to the procurement personnel's confirmation of the completion of the procurement of the purchased products based on the procurement plan data, and to report the purchased products to the quality management subsystem.

[0071] Specifically, the procurement management subsystem includes two modules: procurement planning module and procurement module (outsourcing).

[0072] The procurement plan module is used by the material planner of the material department after logging into his or her account. After receiving the scientific research and production plan, the material planner uses it to issue the procurement plan, that is, to complete the input of procurement plan data into the procurement plan module based on the production plan data.

[0073] Optionally, the procurement plan module can be set with compilation, review, and approval permissions, and different material planners' login accounts correspond to different permissions. For example, the login account of material planner D only has compilation permissions, and the login account of material planner E has compilation permissions and review permissions. He can review or modify the procurement plan data entered into the procurement plan module by material planner D, and can also compile procurement plan data and enter it into the procurement plan module; the login account of material planner F has compilation permissions, review permissions, and approval permissions. He can review or modify the procurement plan data entered into the procurement plan module by material planner D, and can also directly approve the procurement plan data reviewed by material planner D, and can also directly compile procurement plan data and enter it into the procurement plan module.

[0074] The procurement (outsourcing) module is used by the procurement personnel of the materials department to log in to their accounts. After receiving the procurement plan data, the materials procurement personnel will purchase materials, electronic components, electromechanical products and other products.

[0075] In some embodiments, the execution manufacturing subsystem includes a job planning module, an organization production module, and a self-checking module;

[0076] The operation plan module is used to respond to the operation of the scientific research and production scheduling personnel inputting the MES operation plan based on the inspection and test file data set and the product inspection and test data, and send the MES operation plan to the organization production module;

[0077] The production organization module is used to respond to the operation of the workshop dispatcher inputting the first-piece process requirements based on the MES operation plan and process file data set, and to generate a product flow inspection form and a QR code as the unique identifier of the operation plan based on the first-piece process requirements;

[0078] The self-inspection module is used to respond to the workshop processing personnel's operation of uploading the self-inspection results after receiving and completing the self-inspection task based on the product flow inspection form and QR code, and binding the self-inspection results with the QR code of the work plan to which the corresponding product belongs.

[0079] Manufacturing Execution System (MES) is an information system used to manage and monitor the manufacturing process. The Manufacturing Execution System (MES) is usually integrated with the enterprise's PDM system, planning management system, quality management system and other systems to achieve the connection between production planning and actual production and provide the ability to monitor and control the manufacturing process in real time.

[0080] The manufacturing execution system (MES) includes three modules: job planning module, production organization module and self-inspection module.

[0081] The operation plan module is used by the scientific research and production dispatchers of the scientific research and production departments to log in to their own accounts. It is mainly used to issue operation plans. When issuing the operation plan, the corresponding level of the product structure tree of the product data management system (PDM) is selected to implement the standard specifications such as the name and drawing number of the operation plan. The scientific research and production planning module, process management module, inspection and test planning module, and non-conforming product control module (repair / rework order, scrap notification order) will all generate operation plans as the basis for the scientific research and production department to issue the operation plan, that is, to implement the MES operation plan based on the inspection and test file data set and product inspection and test data input.

[0082] The production organization module is used by workshop dispatchers, team leaders, processors and other workshop dispatchers to log in to their own accounts to mobilize workshop resources to organize production; the steps of the workshop production organization module are as follows:

[0083] Step 1: The workshop dispatcher confirms the operation plan number (i.e., MES plan number, which is unique), name, quantity, completion date, batch and other information, and confirms that the materials and technical documents are in place;

[0084] Step 2: The workshop dispatcher compiles the process route according to the process document and enters the first piece process requirements (when the batch quantity is more than three pieces). The computer system automatically generates and outputs the product flow inspection form and QR code (the QR code is the "identity card" of the MES plan); the main workshop dispatcher prints the product flow inspection form;

[0085] Step 3: The workshop dispatcher assigns the MES plan to the corresponding team leader of the workshop;

[0086] Step 4: The corresponding team leader of the workshop assigns the MES plan to the processor.

[0087] The self-inspection module is used by workshop processing personnel who log in to their own accounts. They scan the QR code on the product flow inspection form with a barcode scanner to receive the task. After completing the task, they can conduct self-inspection and upload the self-inspection results. That is, they can upload the self-inspection results after completing the self-inspection task based on the product flow inspection form and the QR code. They can also submit the inspection for special inspection. Self-inspection refers to the inspection conducted by the operator himself, and special inspection refers to the inspection conducted by professional inspectors (who have been trained and obtained the corresponding qualifications).

[0088] Optionally, the self-inspection module may also bind the self-inspection result with the QR code of the operation plan to which the corresponding product belongs, so that other personnel may obtain the self-inspection result by scanning the QR code with a code scanning device.

[0089] In some embodiments, the quality management subsystem includes an inspection and testing module, a quality problem reporting and confirmation module, a review opinion circulation module, and a non-conforming product control module;

[0090] The inspection and testing module is used to respond to the inspection personnel's operation of inputting product inspection results after completing the inspection of purchased products, and to generate and maintain product inspection and testing data based on the product inspection results;

[0091] The quality problem reporting and confirmation module of the quality management submodule is also used to respond to the process inspector's operation of confirming the self-inspection result based on the QR code, and report the quality problem of the product whose self-inspection result does not meet the requirements, obtain the audit opinions entered by the quality representative on the products with reported quality problems, send the audit opinions including the information of products whose quality problems can be modified and improved to the circulation review opinion module, send the audit opinions including the information of products whose quality problems are clear to the non-conforming product control module, and report the information of products whose audit opinions include unclear quality problems or technical document problems to other subsystems of the system in turn, and the other subsystems obtain the audit opinions entered by the corresponding personnel in turn, until the audit opinions include the clarification of the quality problems and then send the product information to the non-conforming product control module, or until the audit opinions include the modification and improvement of the quality problems and then send the product information to the circulation review opinion module.

[0092] Specifically, the quality management subsystem includes an inspection and testing module, a quality problem reporting and confirmation module, a review opinion circulation module, and a non-conforming product control module.

[0093] A) The inspection and testing module is used for the inspection of purchased units such as materials, electronic components, and electromechanical products, product process inspection, product testing, and test result confirmation. After completing the inspection of purchased products, the inspectors enter the product inspection results. The inspection and testing module generates and maintains product inspection and test data based on the product inspection results.

[0094] B) The quality problem reporting and confirmation module is used to report and confirm quality problems that occur during the inspection and testing process; Figure 3 is a flow chart of quality problem reporting and confirmation through the quality problem reporting and confirmation module provided in the embodiment of the present application, such as Figure 3 As shown in the figure, the quality problem reporting and confirmation process includes:

[0095] The quality problem reporting and confirmation module receives product inspection and test data (which can be referred to as inspection and test data for short). The inspector logs in to the quality problem reporting and confirmation module, scans the QR code on the product flow inspection form with a barcode scanner to enter the reporting interface, and reports quality problems for products that "do not meet requirements";

[0096] The quality representative of the main department of this process in the MES system will log in and conduct departmental review;

[0097] There are three options for the audit opinions of departmental audits: "Quality issues are clear", "Quality issues are unclear or there are problems with technical documents", and "Quality issues can be modified and improved".

[0098] The information of products corresponding to the option of "Quality Issues Clear" is directly transferred to the department review module;

[0099] The information of the product corresponding to the option "Unclear quality issue or technical document issue" can first be determined by the authorized process personnel in the process department to determine whether it is a process document issue. If the process personnel can determine it, they will give the conclusion "The quality issue is clear". If no conclusion can be drawn and design participation is required, an authorized designer (the design right belongs to the enterprise) will be selected for review. The process review conclusion and the design review conclusion (when necessary) will be confirmed by the quality management department; when the quality management department confirms "disagreement", the process will be directly returned to the process review module; when the quality management department confirms "requires review by other departments", the process will be assigned to the designated department for handling; after the review by other departments is completed, confirmation by the quality control department is still required; when the confirmation opinion is "review of non-conforming products", it means "the quality issue is clear" and it is transferred to the department review module; when it "disagrees", it will be transferred to the circulation review opinion module, and the process will end after the process-related personnel (quality problem reporter, quality representative) circulate it.

[0100] The "Resubmit after modification and improvement" option directly transfers to the circulation and review opinion module, and the process ends after the process-related personnel (quality problem reporter, quality representative) circulates it.

[0101] In some embodiments, the non-conforming product control module is specifically used to obtain information about products with clear quality problems, output product information and all review opinions on the products, generate a non-conforming review sheet for the products based on the product information and review opinions, or trigger a special review for the products.

[0102] Specifically, Figure 4is a flow chart of reviewing defective products through a defective product control module provided in an embodiment of the present application, such as Figure 4 As shown, the review of non-conforming products includes three-level review, two-level review and one-level review.

[0103] Among them, the three-level review may include: after the quality problem is transferred to the non-conforming product control module for review, the quality representative of the main department of this process in the MES system organizes an on-site quality analysis meeting, notifies the relevant department personnel to conduct the review on-site, and handles the "Non-conforming Review Form" on-site. After the authorized reviewers and responsible unit personnel sign within the scope of the three-level review, the quality representative of the main department of this process in the MES system scans and uploads the "Non-conforming Review Form" signed on-site, and selects relevant technical personnel and responsible units to handle it.

[0104] The second-level review may include: after the quality problem is transferred to the non-conforming product control module for review, the quality representative of the main department of this process in the MES system organizes personnel from relevant departments (process, design (the design right belongs to the enterprise), responsible department) to hold an on-site quality analysis meeting. The on-site quality analysis meeting must clarify the cause of the problem, the responsible unit and the opinions on the actual handling, and handle the "Non-conforming Review Form" on-site. After the authorized technical personnel, responsible unit and quality manager and other personnel within the scope of the second-level review sign in full, the quality representative of the main department of this process in the MES system scans and uploads the "Non-conforming Review Form" signed on site, starts the review process, selects relevant process personnel, and if the design right belongs to the enterprise, the process technicians will review it and select the chief design personnel for review. After the design personnel review it, the permanent institution will review it. The second-level non-conforming product review form needs to be signed by relevant departments when it needs to be signed. If it needs to be signed by the user representative, the responsible department and the permanent institution will ask the user for approval. If the design right does not belong to the enterprise, the process personnel will select it and send it to the quality management department. The quality management department will handle the process and then post the design review opinion after the external design unit reviews it.
