Description

TECHNICAL FIELD

[0001] The present application relates to the field of digital workshop and intelligent manufacturing technology, in particular to a production management system of an electric control system product and a production management method thereof. BACKGROUND

[0002] A digital workshop is a modern workshop designed and built based on informatization and digitization, using advanced production and operation theories and methods such as visualization, standardization and lean management. It is the core unit of an intelligent factory and involves a wide range of fields and complex types.

[0003] An electric control system product is usually composed of several electric control cabinets, actuators, sensors, cables and other equipment, and belongs to the field of system integration production and manufacturing. Considering product production cost, production cycle and quality control, components with the same function usually have multiple alternative brands. Even the configuration of the same series of products will vary with the technical requirements of the project and the customer. In production, there are often complex situations such as material shortage, borrowing and modification. The assembly of an electric control cabinet mainly consists of electrical component assembly and wiring. After decades of development of the electrical industry, most low-voltage electrical components can meet the requirements of 35mm standard rail mounting structure, making assembly simple and convenient for manual operation. In terms of wiring, most current electrical components use spring terminals or screw crimp terminals, but the electrical interfaces of different components differ in spatial position. Electrical components are connected by soft wires, and the wires in a single cabinet are usually hundreds or thousands, crisscrossing each other. In order to facilitate subsequent maintenance and repair, they need to be sorted out and bundled in order. Mechanical automation production cannot fully realize its efficiency and cost advantage.

[0004] In the production execution level of a digital workshop, the manufacturing execution system (MES) platform is usually used to strengthen the execution function of material requirement planning (MRP), link the MRP plan with the workshop operation site control system through the execution system, and improve the manufacturing execution capability of the enterprise. Different industries, enterprises and products have different functional requirements for MES. Ordinary MES systems mainly face the batch production scene of mechanical processing and standardized parts, and cannot meet the digital management and control requirements of the production process of electric control system products with complex and variable product configurations, multi-variety and small-batch production and manual operation as the main mode.

[0005] Generally, the BOM data, drawings and process files of the MES system are obtained by calling relevant system data through a software interface. The interface development cost is high, and the system is easily affected by the running state of other systems. Even the data structure problem may cause difficulties in interface development and unstable operation. SUMMARY

[0006] To solve the above technical problems, the application provides a production management system of an electric control system product and a production management method thereof, which can effectively solve the problems of high investment cost and unstable operation.

[0007] The application is realized by adopting the following technical scheme:

[0012] The material management module is used for receiving material basic data and material requisition data synchronized from the ERP subsystem, receiving materials by secondary warehouse personnel, and recording secondary warehouse inventories; and is used for sorting and dispensing process materials according to a process BOM list.

[0013] The process management module is used for realizing automatic material distribution by scheduling AGV trolleys through the AGV scheduling subsystem; controlling material replenishment records in a late production stage, material unbinding and transfer in a material shifting production, and data records in a material borrowing production.

[0014] The work order management module is also used for comparing material inventories, technical file preparation and self-checking item maintenance during creation of a production work order task, and selecting a specific production mode, wherein the production mode comprises normal production, material shortage production, material shifting production, single-line production and mixed-line production.

[0015] The quality management module is used for compiling a product process quality inspection item library, building product process quality files, and generating corresponding quality inspection items; and is used for freezing or unfreezing in-process products and materials in a production process.

[0016] The personnel management module is used to implement personnel login and the management of roles and permissions. The MMS subsystem synchronizes the personnel account information of the IAM subsystem and uses the same set of account passwords for login authentication.

[0017] The MMS subsystem includes an MMS database and an intermediate database. When data changes in the ERP subsystem, it automatically triggers data transmission to the intermediate database. The MMS subsystem retrieves data from the intermediate database according to scheduled tasks. When the electrical control system product completes a certain production node task, the MMS subsystem uploads the work report data to the work report table in the intermediate database. The ERP subsystem periodically monitors the work report table in the intermediate database and processes the work report data in a timely manner.

[0018] A production management method for an electronic control system product, characterized by the following steps:

[0019] S1. Create a standard serialized design BOM template, which includes material attributes, including general attributes and special attributes. The special attributes include material status attributes, class attributes, substitution attributes, process attributes, quality inspection attributes, and control intensity attributes.

[0020] S2. Designers fill in the standard series design BOM list template with the general attribute information of all materials required for this series of products to form the standard series design BOM list;

[0021] S3. Based on the specific requirements of the project, the designers mark the special attributes of the materials in the standard serialized design BOM list created in step S2 to clarify the specific materials required for the project, thereby forming the design BOM list for the specific project. The MMS subsystem extracts the process BOM list through the material attribute markings in the design BOM of the specific project.

[0022] S4. Designers create projects through the MMS subsystem, import the specific project's design BOM list, technical drawings, and technical disclosure documents into the MMS subsystem, and select relevant personnel to review the documents according to the preset approval process;

[0023] S5. Relevant personnel in the approval process confirm all material attributes of the project in turn, and finally form a finalized design BOM list and assign version tags;

[0024] S6. The MMS subsystem interfaces with the ERP subsystem to obtain material master data, inventory data, work order data, and material requisition data; production scheduling personnel compare the determined design BOM list with the inventory data to determine a specific production mode, check whether production technology is ready, and if so, prepare a production work order and issue it to the production line; wherein the production mode includes normal production, material shortage production, modification production, single-line production, and mixed-line production;

[0025] S7. Material points are collected according to the material requisition of the project synchronized from the ERP subsystem, and the collected materials are accounted in the warehouse; material sorting is performed according to the process BOM list bound by the production work order, and the sorted materials are bound with material frames, shelves, landmarks, cabinet bodies, and cabinet body carriers;

[0026] S8. Production personnel push the cabinet body to be assembled into the assembly line, scan the cabinet body barcode on the cabinet body to be assembled, the MMS subsystem calls the AGV scheduling subsystem to control the AGV to deliver materials to the corresponding work station, and complete the assembly of the cabinet body at the work station;

[0027] S9. Several cabinet bodies of the same set of electrical control system products enter the same assembly line or different assembly lines in a certain order for assembly operation;

[0028] S 10 . The completed electrical control cabinet is transferred to the wiring area by the AGV trolley for wiring, material supplementing, or assembly inspection operation;

[0029] S 11 . Final inspection personnel perform final inspection on the debug-qualified product, upload the quality file of the equipment, give a final inspection judgment of the product, and then report the work to the ERP subsystem.

[0030] In step S5, the relevant personnel in the approval process confirm all materials of the project in turn, specifically: the MMS subsystem screens out materials not needed for the project from the standard series design BOM list, and displays the determined materials and the temporarily undetermined multi-brand materials; the process personnel check whether there are new materials for the project, if so, supplement the process attributes, and retrieve relevant standard operation items from the process library to combine into the production operation instruction book of the project; the quality control personnel check whether there are new materials for the project, if so, supplement the quality attribute and control intensity attribute, and retrieve relevant operation sub-items from the quality inspection operation library to combine into the process quality control file of the project; the planning personnel arrange the corresponding production and procurement plan according to the material attribute to extract the relevant material production and procurement attribute; the procurement personnel mark the state attribute of the corresponding multi-brand material in the design list according to the procurement bidding or price comparison result.

[0031] In step S8, after scanning the cabinet barcode on the cabinet to be installed, the MMS subsystem displays the relevant electronic operation manuals associated with the project on the corresponding display screen, including text and image operation instructions, assembly self-inspection items, and layout diagrams.

[0032] Step S9 may specifically include: in the cabinet assembly section, after the previous worker starts work, the next worker calls the AGV to deliver the materials required by the cabinet in the previous process to the workstation in advance; after the cabinet completes the previous assembly, the next worker drags the cabinet from the previous process into the workstation for assembly; and so on to complete all the cabinet assembly work.

[0033] Step S 10 The replenishment operation in the MMS subsystem specifically refers to the following: when replenishment is required and the materials needed for the project have arrived, production personnel retrieve the materials from the secondary warehouse, query the corresponding shortage cabinet on the MMS subsystem, and then go to the corresponding location to perform the replenishment operation under the guidance of the MMS subsystem.

[0034] Step S 10 and S 11 The process also includes: the commissioning personnel assembling the electrical control cabinet, along with the actuators, sensors, and cables from the warehouse, by scanning the barcodes, entering the production serial number of the complete set of products, and then performing commissioning operations according to the commissioning requirements.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1. This invention addresses the structural and production characteristics of electrical control system products composed of several electrical control cabinets, actuators, sensors, cables, and other equipment. It develops a management system integrating multiple system functions, solidifying the control method for digital production workshops of electrical control system products. This method features flexible production organization, good compatibility, low investment cost, and short construction period. It meets the production needs of most electrical control cabinets, adapts to complex production environments, facilitates the digitalization and lean manufacturing of the production process, and promotes improved quality and efficiency in the production of electrical control system products.

[0037] 2. This management system optimizes and integrates the functions of multiple systems, such as warehouse management system, production management and quality inspection, electronic operation manual, product lifecycle management, and process design. It brings together relevant personnel from technology, process, quality, scheduling, production, and warehousing, and builds an efficient collaborative platform around the product delivery center. This improves the system's response speed and enables it to cope with complex and ever-changing design and production scenarios. It has fewer external system connections, operates relatively independently, is not easily affected by the operating status of other systems, and operates stably.

[0038] 3、The system divides the production process of the electric control system product into multiple work sections, and keeps a certain independence while being connected with each other.

[0039] 4、The data integration mode of the intermediate database ensures the relative independence of the MMS subsystem operation, and reduces the influence of the ERP subsystem failure on the workshop production operation.

[0040] 5、The integration of the MMS subsystem and the IAM subsystem aims to unify the user authentication permission, avoid the risk of account and password leakage, simplify the operation, and reduce the login failure caused by password confusion when logging in different systems. The MMS subsystem provides an interface to accept the data actively pushed by the main data system in a timely manner as a data application party. The MMS subsystem calls the interface of the IAM subsystem unified user identity management system to synchronize the user information.

[0041] 6、The quality management module is used for freezing or unfreezing operation on the work-in-process and materials in the production process, which can reduce the output of abnormal products.

[0042] 7、The electric control system product is usually composed of several electric control cabinets, actuators, sensors, cables and other equipment. The MMS subsystem can automatically decompose the order issued according to the set into several sub-orders, then produce according to the respective process flow, finally realize the binding of the set in the debugging stage, and report the work to the ERP subsystem according to the set. Simplify the tedious work of manual splitting and merging of product BOM and production order.

[0043] 8、The MMS subsystem is compatible with the material bar code and two-dimensional code of customers and suppliers, reduces a large amount of unnecessary secondary coding work of materials, and can realize customized management and control of materials.

[0044] 9、The MMS subsystem can independently implement the management of production materials, sort the materials according to the process requirements, dispatch the AGV car to deliver the materials to the designated production station, and possibly complete the pre-feeding and feeding, shorten the production waiting time, and improve the production efficiency.

[0045] 10. The design of components in electronic control system products undergoes frequent changes. Following conventional production methods, personnel involved in technology, processes, quality control, scheduling, production, and warehousing typically operate in separate systems, resulting in lengthy processes, untimely information transmission, and other inefficiencies. The management method of this invention integrates all relevant personnel into a unified platform for direct communication, eliminating lengthy intermediate steps, enabling rapid response, and improving information transmission efficiency. When technical changes occur during product manufacturing, designers can promptly modify the standard BOM (Bill of Materials) for the product series and upload it to the MMS (Manufacturing Management System) subsystem. Subsequent personnel can use the MMS subsystem's reporting function to submit version difference reports, modify the differing material information, and perform corresponding operations. This ensures timely transmission of change information to the production line, allows for finished product information queries based on pre-defined plans, intercepts work-in-process status, and implements corrective measures according to the latest technical requirements.

[0046] 11. The MMS subsystem can coexist with the company's regular PLM, WMS, and ERP subsystems, or operate independently. The data used by the MMS subsystem comes from the original design data of the designers, and the system assists them in completing the version validity management of the original data; the standardized BOM list for serialized products can reduce the design workload of designers and avoid errors and confusion in references during copying and modification.

[0052] As a basic embodiment of the present invention, the present invention includes an electronic control system product production management system, comprising an MMS subsystem, an AGV scheduling subsystem, an ERP subsystem, and an IAM subsystem. The MMS subsystem is integrated with the AGV scheduling subsystem, the ERP subsystem, and the IAM subsystem to achieve digital control of the production process. More specifically, the MMS subsystem includes a master data management module, a work order management module, a production execution module, a quality management module, a material management module, a personnel management module, a technical document module, a process management module, and a process management module.

[0053] The work order management module is used to receive production order tasks synchronized from the ERP subsystem, create specific production work order tasks, and send them to the production line.

Figure 1 It includes an MMS subsystem, an AGV scheduling subsystem, an ERP subsystem, and an IAM subsystem. The MMS subsystem is integrated with the AGV scheduling subsystem, ERP subsystem, and IAM subsystem to achieve digital control of the production process. More specifically, the MMS subsystem includes a master data management module, a work order management module, a production execution module, a quality management module, a material management module, a personnel management module, a technical document module, a process management module, and a process management module.

[0059] The quality management module is used to compile a product process quality inspection item library, then build product process quality documents according to the product quality control requirements of specific projects, and conduct online approval and publication. After approval, corresponding quality inspection items are generated according to different products and processes. It is also used to freeze or thaw work-in-process and materials during the production process to reduce the output of abnormal products.

[0060] The technical document module is used to upload production design BOMs, technical drawings, and technical documents. Furthermore, uploaded documents undergo validity management, requiring personnel review before use. Assembly and quality personnel can view relevant drawing information through reports, achieving paperless technical document transfer.

[0061] The process management module mainly serves process personnel, and can compile a standard production process operation item library according to a template. Then, a production process route is planned according to product technical requirements of a specific project, a production operation guide book is built, and is uploaded to an electronic operation guide book. The MMS subsystem automatically matches and displays corresponding electronic operation guide file instructions according to different products.

[0062] In the embodiment, the ERP subsystem is exemplified by SAP.

[0063] Referring to the drawings Figure 3 The MMS subsystem obtains material inventory, material requisition, customer, supplier, model, work order and other data of the first-level library through integration with the SAP system, and feeds back result information to the SAP subsystem after completing corresponding production tasks. The MMS subsystem includes an MMS database and an intermediate database. When data changes in the SAP subsystem, data is automatically triggered to the intermediate database, and the MMS subsystem pulls data from the intermediate database according to a timing task. When a work-in-process completes a certain production node task, the MMS subsystem uploads work reporting data to the intermediate library work reporting table, and the SAP subsystem monitors the intermediate library work reporting table in a timely manner, and processes the work reporting data in a timely manner. Through the data integration mode of the intermediate database, the relative independence of the MMS subsystem is ensured, and the influence of the SAP subsystem on fault workshop production operation is reduced.

[0064] More specifically, the work order management module is used to receive production order tasks synchronized from the SAP subsystem, create specific production work order tasks and issue them to production lines. In the work order creation process, the dispatcher can compare material inventory, technical file preparation and self-check item maintenance through the work order management module, and select a specific production mode, such as normal production, material shortage production, modification production, single-line production or mixed-line production.

[0065] The production execution module is used to control production processes according to production process flow, bind information such as people, materials, products, time and process, complete production work reporting of the MMS subsystem, and feed back order execution status to the SAP subsystem according to pre-set work reporting nodes of the MMS subsystem and the SAP subsystem, so as to realize consistency of work reporting data of the MMS subsystem and the SAP subsystem.

[0066] The material management module is used to receive material basic data and material requisition data synchronized from the SAP subsystem, then a secondary library personnel points to collect materials, ensures consistency between physical objects and accounts, and enters the secondary library inventory into the account. It is also used to sign off materials temporarily not accounted for in the first-level library as subsequent first-level library account closing vouchers, and to sort and distribute process materials according to process BOM lists.

[0067] The MMS subsystem is integrated with the IAM subsystem to unify user authentication authority, avoid account password leakage risk, simplify operation, and reduce personnel login failure due to password confusion when logging in different systems. The MMS subsystem acts as a data application party to provide an interface to accept data actively pushed by the master data system. The MMS subsystem calls the interface of the IAM subsystem unified user identity management system to synchronize user information.

[0068] More specifically, the personnel management module is used to realize personnel login, role and permission management. For employees with accounts in the IAM subsystem, the MMS subsystem can synchronize personnel account information of the IAM subsystem, and use the same set of account passwords for login authentication. For outsourced personnel without accounts in the IAM subsystem, a user and password information can be created in the system to realize login, role and permission management. The password should contain uppercase letters, lowercase letters, numbers and special symbols, and be at least 8 bits to ensure the strictness and security of the password.

[0069] The MMS subsystem is integrated with the AGV scheduling subsystem to schedule AGV cars to complete distribution tasks.

[0070] More specifically, the process management module is used to realize automatic distribution of materials by scheduling AGV cars through the AGV scheduling subsystem; control the material replenishment record after material shortage production, material transfer of material shifting production, and data record in material borrowing production.

[0071] A production management method using the above-mentioned electric control system product production management system, with reference to the description of the accompanying drawings Figure 2 , comprising the following steps:

[0072] S 1. A standard series design BOM list template is created by using WPS table software, which includes material properties, including regular properties and special properties. The special properties include state properties, class properties, replacement properties, process properties, quality inspection quality properties and control intensity properties. The regular properties include part number, material code, name, model number, quantity, and brand information.

[0073] S2. The designer fills all the regular property information of the materials required by the series product into the standard series design BOM list template to form the standard series design BOM list.

[0074] S3. The designer marks the special properties of the materials in the standard series design BOM list created in step S2 according to the specific requirements of the project to specify the specific materials required by the project, thereby forming the design BOM list of the specific project, and the MMS subsystem extracts the process BOM list from the material property marking in the design BOM of the specific project. Among them, marking the special properties of the materials specifically refers to: the designer marks the class properties and alternative properties, and the process personnel mark the process properties of the materials according to the requirements of the product production process; and the quality inspection quality properties and control strength information of the related materials are marked in the table according to the product quality requirements.

[0075] S4. The designer creates a project through the MMS subsystem, and imports the design BOM list, technical drawings and technical disclosure files of the specific project into the MMS subsystem, and selects relevant personnel for file review according to the preset approval process.

[0076] S5. The relevant personnel in the approval process confirm all the material properties of the project in turn, and finally form a determined design BOM list and give a version label, for example V1.0. More specifically, the MMS subsystem masks the materials that are not needed by the project in the standard series design BOM list, displays the determined materials and the multiple-brand materials that are temporarily not determined; the process personnel in the process check whether there are new materials in the project, if so, mark their process properties, and combine the related standard operation items from the process library into the production operation instruction book of the project; the quality control personnel in the process check whether there are new materials in the project, if so, mark their quality quality properties and control strength properties, and combine the related operation sub-items from the quality inspection operation library into the process quality control file of the project; the planning personnel arrange the corresponding production and procurement plans according to the material properties; and the procurement personnel mark the state properties of the corresponding materials in the design list according to the procurement bidding or comparison results.

[0077] S6. The MMS subsystem interfaces with the SAP subsystem to obtain material master data, inventory data, work order data and material requisition data. The production scheduling personnel compare the determined design BOM list with the inventory data to determine the specific production mode, check whether the production technology is ready, if so, prepare the production work order and issue it to the production line. Among them, the production mode includes normal production, material shortage production, modification production, single-line production and mixed-line production.

[0078] S7. The warehouse personnel of the secondary warehouse take the material points according to the project order from the SAP subsystem to the primary warehouse, and the materials are accounted for in the warehouse. Then, according to the process BOM list bound by the production order, the materials are sorted, and the sorted materials are bound with the material frame, material shelf, landmark, cabinet body, and cabinet body carrier. The order is issued in the SAP subsystem, which is the voucher for the secondary warehouse personnel (line-side warehouse) to take materials to the primary warehouse.

[0079] S8. The production personnel push the cabinet to be assembled into the assembly line, start the client software on the touch screen all-in-one machine, scan the cabinet barcode on the cabinet to be assembled, and the MMS subsystem presents the relevant electronic operation guide book bound by the project on the corresponding display screen, including text and image operation instructions, assembly self-check items, and layout diagrams. At the same time, the MMS subsystem calls the AGV scheduling subsystem to control the AGV to deliver materials to the corresponding station. The production personnel assemble according to the electronic operation guide book requirements, and important materials need to be scanned with the material code, and the system automatically records. In the cabinet assembly section, after the current sequence personnel start work, the next sequence personnel can call the AGV through the electronic operation guide book interface to deliver the materials required by the previous sequence cabinet in the process to the station in advance. After the cabinet completes the previous sequence assembly, the next sequence personnel push the previous sequence cabinet into the reordering assembly. In this way, the assembly of the cabinet is completed sequentially.

[0080] S9. Several cabinets of the same set of electrical control system products enter the same assembly line or different assembly lines in a certain order for assembly operation;

[0081] S 10 . The completed electrical control cabinet is transferred to the wiring area by the AGV trolley for wiring, material supplementing, or assembly inspection operation. When wiring, the wiring personnel bind the cabinet and the landmark where it is located through the handheld PDA / PAD client to determine the spatial position, then perform the wiring operation according to the operation requirements, and fill in the relevant self-check data.

[0082] S 11 . When the required materials of the project arrive, the production personnel can take out the materials from the secondary warehouse and query the relevant material shortage cabinets through the PDA or PAD client, and perform the material supplementing operation according to the system guidance to the corresponding position. The MMS subsystem supports the intermittent operation mode of quality control personnel and wiring personnel, that is, the inspection personnel and wiring personnel can complete the inspection and wiring operation of a cabinet in multiple times to meet the material shortage production demand.

[0083] S 12. The project inspection qualified electric control cabinet body continues to be transferred to the debugging area by the AGV trolley to carry out system assembly, and the debugging personnel uses the continuous PDA / PAD to scan the code of the assembled electric control cabinet body, as well as part of the actuator, sensor, cable and the like taken from the warehouse, and carries out debugging operation according to the debugging operation requirements.

[0084] S 13 . The final inspection personnel carry out final inspection on the debugging qualified product, upload the quality file of the equipment and give the final inspection judgment of the product, and then report the work to the ERP subsystem.

The related technology, process and quality inspection requirements of the in-process cabinet body can be inquired by scanning the code through the APP, and the compliance and quality attribute of the inspected in-process product are judged.

[0086] In the whole production and debugging process of the electric control system product, the MMS subsystem can automatically record the product information when the relevant personnel scan the material code, and can distinguish and control the material according to the material quality attribute and control strength in the design BOM, so as to avoid the use of wrong material or wrong collocation of material.

The MMS subsystem extracts the process BOM list through the material attribute markings in the design BOM of the specific project. S4. Designers create projects through the MMS subsystem, import the specific project's design BOM list, technical drawings, and technical disclosure documents into the MMS subsystem, and select relevant personnel to review the documents according to the preset approval process; S5. Relevant personnel in the approval process confirm all material attributes of the project in turn, and finally form a finalized design BOM list and assign version tags; S6. The MMS subsystem interfaces with the ERP subsystem to obtain material master data, inventory data, work order data, and material requisition data; Production schedulers compare the finalized design BOM list with inventory data to determine the specific production mode and check whether the production technology is ready. If so, they prepare production work orders and issue them to the designated production lines. The production modes include normal production, production in short supply, production with material shortages, production with material transfer, single-line production, and mixed-line production. S7. Based on the material requisition form synchronized from the ERP subsystem, collect the materials and put them into the warehouse and record them in the books; then sort the materials according to the process BOM list bound to the production work order, and bind the sorted materials to the material frame, material rack, landmark, cabinet, and cabinet carrier; S8. Production personnel push the cabinet to be assembled into the assembly line, scan the cabinet barcode on the cabinet, the MMS subsystem calls the AGV scheduling subsystem, controls the AGV to deliver the material to the corresponding workstation, and completes the assembly of the cabinet at that workstation. S9. Several cabinets of the same electrical control system product are sequentially entered into the same assembly line or different assembly lines for assembly operations in a certain order; S 10 The assembled electrical control cabinet is then transported to the wiring area via AGV (Automated Guided Vehicle) for wiring, material replenishment, or assembly inspection operations. S 11 The final inspection personnel conduct a final inspection of the products that have passed the debugging process, upload the equipment's quality documents, provide the final inspection assessment of the products, and then report the work to the ERP subsystem.

6. The production management method for an electronic control system product according to claim 5, characterized in that: In step S5, the relevant personnel in the approval process confirm all materials for the project in turn. Specifically, the MMS subsystem shields materials that are not needed for the project in the standard serialized design BOM list, and displays confirmed materials and multi-brand materials that are not yet confirmed. The process personnel in the process check whether there are any new materials for the project. If so, they add and mark their process attributes, and retrieve the relevant standard operation items from the process library to combine them into the production operation instructions for the project. In the process, the quality control personnel check whether there are any new materials for the project. If so, they add the quality attributes and control intensity attributes, and retrieve the relevant sub-items from the quality inspection operation library to form the process quality control document for the project. In the process, planners extract relevant material production and procurement attributes based on material properties and arrange corresponding production and procurement plans. In the process, procurement personnel mark the status attributes of corresponding multi-brand materials in the design list based on the results of procurement bidding or price comparison.

7. The production management method for an electronic control system product according to claim 5, characterized in that: In step S8, after scanning the cabinet barcode on the cabinet to be installed, the MMS subsystem displays the relevant electronic operation manuals associated with the project on the corresponding display screen, including text and image operation instructions, assembly self-inspection items, and layout diagrams.

8. The production management method for an electronic control system product according to claim 5, characterized in that: Step S9 may specifically include: in the cabinet assembly section, after the previous worker starts work, the next worker calls the AGV to deliver the materials required by the cabinet in the previous process to the workstation in advance; after the cabinet completes the previous assembly, the next worker drags the cabinet from the previous process into the workstation for assembly; and so on to complete all the cabinet assembly work.

9. A production management method for an electronic control system product according to claim 8, characterized in that: Step S 10 The replenishment operation in the MMS subsystem specifically refers to the following: when replenishment is required and the materials needed for the project have arrived, production personnel retrieve the materials from the secondary warehouse, query the corresponding shortage cabinet on the MMS subsystem, and then go to the corresponding location to perform the replenishment operation under the guidance of the MMS subsystem.

10. A production management method for an electronic control system product according to claim 5, characterized in that: Step S 10 and S 11 The process also includes: the commissioning personnel assembling the electrical control cabinet, along with the actuators, sensors, and cables from the warehouse, by scanning the barcodes, entering the production serial number of the complete set of products, and then performing commissioning operations according to the commissioning requirements.
