Description

Technical Field

[0001] This invention relates to the field of intelligent warehousing and materials management technology, specifically to a closed-loop control method and system for materials based on intelligent warehouse management. Background Technology

[0002] Currently, industrial enterprises and warehousing management scenarios have typically introduced intelligent warehouse management systems for material management. Existing systems mostly manage inbound, outbound, storage location, and inventory quantity changes, meeting general warehousing operation needs. However, in scenarios involving new material issuance and old material return, as well as repair and reuse, they still struggle to support continuous management of target materials from issuance to reuse. The material issuance process usually only focuses on whether the material issuance application is approved and whether inventory is sufficient, lacking unified constraints on issuance qualifications, old material return requirements, and the status of submitted scrap materials. This easily leads to problems such as new materials being issued while old materials are not returned, discrepancies between actually returned materials and the required old materials, and difficulty in verifying the completeness of returned materials. After equipment installation or component replacement, the installation status of new parts and the removal status of old parts are often recorded separately. Whether old parts are returned as required and whether the returned old parts correspond to the original replacement object is difficult to verify continuously using the same material identifier. Once waste materials enter the repair and reuse process, the existing management methods mostly rely on manual ledgers or independent processes. It is difficult to form a stable basis for the circulation of waste materials, such as whether the repair process is completed and whether the repaired materials can be reclaimed. This results in reusable materials being left for a long time or being disposed of prematurely.

[0003] In the above scenarios, the main problem is not the lack of records at individual storage nodes, but the lack of a closed-loop relationship between the same target material and the processes of issuing new materials and exchanging old materials, dismantling and recycling old materials, repairing and disposing of old materials, and synchronizing inventory. If the issuance of new materials and the exchange of old materials only stays at the approval level, it is difficult to form a strong binding between the recycling of old materials and the issuance of new materials. If the repair and reuse of old materials only stays at the manual registration level, it is difficult for the repaired materials to re-enter the usable inventory. If the smart warehouse only records quantity changes, the inventory data is difficult to reflect the true state of the target material after it has been issued, exchanged, repaired, and reused. Summary of the Invention

[0004] In view of the above-mentioned problems, the present invention is proposed.

[0005] Therefore, the technical problem solved by this invention is that existing intelligent warehouse-based material management methods have problems such as insufficient constraints on issuing new materials and exchanging old ones, disconnection between repair and reuse, untimely synchronization of repaired material inventory, and low traceability of the entire material life cycle. The invention also addresses how to achieve closed-loop management of target materials in terms of issuance, exchange, repair, reuse, and inventory synchronization.

[0006] To address the aforementioned technical problems, this invention provides the following technical solution: a closed-loop material management method based on intelligent warehouse management, comprising: forming a closed-loop material management object based on the full lifecycle circulation data of the target material; generating a new / used reuse tag chain in the closed-loop material management object, updating the link node status in the new / used reuse tag chain in response to the closed-loop circulation event of the target material; performing link consistency verification based on the link node status to form a material closed-loop constraint state; generating a warehousing action lock control result based on the material closed-loop constraint state, and controlling the issuance of corresponding warehousing execution instructions based on the warehousing action lock control result; receiving the returned warehousing execution receipt, and generating a write-back verification key based on the warehousing execution receipt; performing idempotency verification on the warehousing execution receipt based on the write-back verification key, and writing back the warehousing execution result to the corresponding link node of the new / used reuse tag chain when the verification passes, forming a warehousing linkage state; and generating a material closed-loop management result based on the written-back link node status.

[0007] As a preferred embodiment of the material closed-loop management method based on intelligent warehouse management described in this invention, the material closed-loop management object includes a full-process traceability ledger formed based on the material tag information of the target material; the full-process traceability ledger inherits the link node status in the new and old reuse tag chain, and writes the object correspondence of the target material in the closed-loop circulation process into the same traceability record.

[0008] As a preferred embodiment of the material closed-loop control method based on intelligent warehouse management described in this invention, the material closed-loop constraint state includes the new material issuance and old material exchange access results; the new material issuance and old material exchange access results are formed based on the new material issuance and old material exchange rules, issuance qualifications, and the submission status of scrap materials; when the new material issuance and old material exchange access results meet the first access requirement, the target material is associated with the warehousing linkage path of new material outbound and scrap material inbound; when the new material issuance and old material exchange access results do not meet the first access requirement, the target material is associated with either the issuance restriction path or the old material exchange anomaly warning path.

[0009] As a preferred embodiment of the closed-loop material control method based on intelligent warehouse management described in this invention, the link consistency verification includes: forming a compliance status for old material delivery based on the correspondence between the actual old material delivery label and the old material delivery object identifier; when the actual old material delivery label matches the old material delivery object identifier and the old material integrity status meets the old material delivery conditions, the compliance status for old material delivery is written as a qualified old material delivery status; when the actual old material delivery label does not match the old material delivery object identifier, or the old material integrity status does not meet the old material delivery conditions, the compliance status for old material delivery is written as an abnormal old material delivery status.

[0010] As a preferred embodiment of the material closed-loop control method based on intelligent warehouse management described in this invention, the material closed-loop constraint state further includes the installation, replacement, and handover binding result; the installation, replacement, and handover binding result is formed based on the installation confirmation result after the new material leaves the warehouse and the handover confirmation result after the old material is removed, and is written into the new and old reuse tag chain through the same closed-loop object number; when the installation confirmation result of the new material has been formed but the handover confirmation result of the old material has not been formed, the installation, replacement, and handover binding state remains in the pending handover locked state.

[0011] As a preferred embodiment of the closed-loop material management method based on intelligent warehouse management described in this invention, the closed-loop constraint state of the materials further includes the results of repair and reuse circulation; the results of repair and reuse circulation are formed based on the classification and testing results of waste materials, the repairability assessment results, and the repair and reuse declaration status; when the waste materials meet the first repairability condition, the target materials are associated with the repair circulation path; when the waste materials do not meet the first repairability condition, the target materials are associated with the irreparable disposal path.

[0012] As a preferred embodiment of the material closed-loop control method based on intelligent warehouse management described in this invention, the method further includes: forming a reuse level based on the performance test results after repair, forming a reuse allocation result based on the reuse level; the reuse allocation result is associated with a corresponding requisition scenario or a designated storage area; when the reuse allocation result meets the reuse release conditions, the reuse lock of the corresponding closed-loop object is released, and the repaired material is associated with the corresponding requisition scenario or designated storage area.

[0013] As a preferred embodiment of the material closed-loop control method based on intelligent warehouse management described in this invention, the following are included: the warehouse linkage state includes: a warehouse linkage result formed based on the material closed-loop constraint state; generating a corresponding warehouse execution instruction based on the warehouse action lock control result, and sending the warehouse execution instruction to the intelligent warehouse management system; receiving a warehouse execution receipt returned by the intelligent warehouse management system, and generating a write-back verification key based on the warehouse execution receipt; when the write-back verification key does not exist in the material closed-loop management object, writing the warehouse execution result back to the corresponding link node of the new and old reuse tag chain to form the inventory synchronization basis of the material closed-loop control result; when the write-back verification key already exists in the material closed-loop management object, preventing the corresponding warehouse execution receipt from being repeatedly written back.

[0014] Another objective of this invention is to provide a closed-loop material management system based on intelligent warehouse management. This system can form a closed-loop management object of the entire lifecycle flow data of the target material through data interaction between the object filing module, constraint representation module, and warehouse synchronization module. Based on the closed-loop management object, a closed-loop constraint state and a warehouse linkage state are formed. This solves the problems in existing intelligent warehouse management technologies, such as the disconnect between the relationship between new material issuance and old material exchange and the relationship between repair and reuse, the unclear synchronization relationship between repaired materials and inventory, and the lack of closed-loop management of target materials in the process of issuance, old material exchange, repair, and reuse.

[0015] As a preferred embodiment of the material closed-loop management system based on intelligent warehouse management described in this invention, it includes: an object filing module, a constraint representation module, and a warehouse synchronization module; the object filing module forms a material closed-loop management object based on the full life cycle flow data of the target material and the material tag information, and writes the object correspondence formed by the target material from the triggering of new material demand, through the return of old materials and the repair and disposal of old materials to the reuse of inventory into the full process traceability ledger;

[0016] The constraint representation module forms a material closed-loop constraint state based on the material closed-loop management object, and associates the new material issuance and old material exchange access results, old material exchange compliance results, installation, replacement and old material exchange binding results, repair and waste utilization circulation results, and reuse allocation results with the closed-loop object correspondence of the target material. The warehouse synchronization module forms a warehouse linkage state based on the material closed-loop constraint state, and writes back the material closed-loop management object after synchronizing and associating the new material outbound, the scrap material inbound, and the inventory changes of reused materials with the inventory data of the intelligent warehouse management system, thus forming the material closed-loop control result.

[0017] Another object of the present invention is to provide a material closed-loop control device based on intelligent warehouse management, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the material closed-loop control method based on intelligent warehouse management.

[0018] Another object of the present invention is to provide a material closed-loop control storage medium based on intelligent warehouse management, wherein a computer program is stored thereon, and when the computer program is executed by a processor, the steps of the material closed-loop control method based on intelligent warehouse management are implemented.

[0019] The beneficial effects of this invention are as follows: The material closed-loop management method based on intelligent warehouse management provided by this invention incorporates the new material issuance demand, old material return, repair disposal, and reuse inventory into the same closed-loop object relationship through the material closed-loop management object. This reduces the breaks between issuance records, old material return records, repair records, and inventory records, making material flow traceability more complete and object relationships clearer. By using the material closed-loop constraint state to coordinately constrain the new material issuance and old material return relationship and the repair and reuse relationship, the issuance of new materials is no longer separated from the old material return state, and the recycling of waste materials is no longer separated from the repair and reuse judgment, improving the accuracy of new material issuance and old material return access control and the standardization of repair and reuse flow. By using the warehouse linkage state to synchronously link the new material outbound, waste material inbound, and reuse material inventory changes with the intelligent warehouse inventory data, the repaired materials can re-enter the inventory management link, reducing the risk of inconsistency between book inventory and physical status. This invention achieves better results in material closed-loop traceability, new material issuance and old material return constraints, repair and reuse, and intelligent warehouse inventory synchronization.

Detailed Implementation

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] Before proceeding to specific embodiments, the following explanation of the higher-level technical terms is provided to ensure that the specification can support the technical features expressed in the abstract claims.

[0030] In this embodiment, "target materials" specifically refers to electrical control boards that require management of new issuance and old replacement, as well as repair and reuse. These electrical control boards include newly issued boards, old boards removed from equipment, and reusable boards that have been repaired and reintroduced into the warehousing system. By selecting the same type of material throughout the embodiment, the unclear technology chain caused by repeated switching between different material categories can be avoided.

[0031] In this embodiment, "full lifecycle data" specifically refers to the demand plan, purchase order, delivery reservation, delivery acceptance, physical shelving, material requisition, outbound confirmation, installation confirmation, old parts removal, old parts return, scrap material warehousing, repair application, repair process, performance testing, reuse allocation, and inventory synchronization data generated around the same electrical control board. This data is not general business data, but rather continuous status data of the target material from the generation of new demand to its re-entry into inventory after repair.

[0032] In this embodiment, "Materials Closed-Loop Management Object 100" specifically refers to the object record formed with the material tag of the electrical control board as the main index. This object record writes the issuance of new control boards, the return of old control boards, the repair of old control boards, and the reuse inventory of repaired control boards into the same object relationship. Materials Closed-Loop Management Object 100 is not an ordinary inventory ledger, but a data object that manages new parts, old parts, and reused parts under the same closed-loop link.

[0033] In this embodiment, "material label information" specifically refers to the QR code label on the electrical control board that is read via a PDA, outbound machine, or mobile device. This QR code label establishes a correspondence with the material code, specifications, batch number, storage location, and equipment number, and is used to identify whether a new control board, an old control board, and a repaired control board belong to the same closed-loop link.

[0034] In this embodiment, the "full-process traceability ledger" specifically refers to a continuous record table that uses material tags as the primary key and links them to material requisition forms, equipment numbers, installation records, handover records, and repair records. This ledger is used to record the complete status of target materials from arrival and warehousing, material requisition and issuance, installation and replacement, old parts return, repair and processing, to reuse and warehousing.

[0035] In this embodiment, "receiving a new electrical control board and returning an old one" specifically refers to the system simultaneously generating a return request for an old electrical control board when a maintenance worker receives a new one, and binding the new control board's outbound record with the old control board's return record.

[0036] In this embodiment, "repairing and reusing old equipment" specifically refers to the system determining whether to enter the repair process based on the test results after the old electrical control board is returned; after the repair is completed, the system determines whether to re-enter the usable inventory or enter the unrepairable disposal path based on the performance test results.

[0037] In this embodiment, “collaborative constraint representation” specifically means that the system does not judge material issuance and repair separately, but instead records the new material issuance access, old material return compliance, installation and replacement binding and repair flow status simultaneously in the same material closed-loop management object 100, thereby forming a controllable status result for subsequent issuance, receipt and inventory write-back.

[0038] "Materials Closed-Loop Constraint Status 200" in this embodiment specifically refers to the set of statuses formed by the new-to-old exchange access result 201, old-to-old exchange compliance result 202, installation / replacement / old-to-old exchange binding result 203, and repair / reuse circulation result 204. This set of statuses can be specifically represented by system statuses such as allowed outbound, restricted outbound, pending old-to-old exchange, old-to-old exchange completed, old-to-old exchange abnormal, pending repair, repairable, unrepairable, and pending reuse.

[0039] "New Material Requisition and Old Material Delivery Access Result 201" in this embodiment specifically refers to the judgment result generated by the system before the new electrical control board is issued. The system determines whether the material requisition application is allowed to enter the issuance process based on the user's permissions, requisition quota, and the submission status of the old control board.

[0040] The "new-for-old rule" in this embodiment specifically refers to the rules pre-configured by the administrator. For example, when a new electrical control board is issued, an old electrical control board should be returned. The old control board should be returned within a specified period, and the core board of the old control board should be complete and the label should be identifiable.

[0041] In this embodiment, "requisition qualification" specifically refers to whether the maintenance personnel have the authority to requisition electrical control boards, and whether the current requisition quantity exceeds the requisition quota for their corresponding position or department.

[0042] In this embodiment, "submission status of scrap materials" specifically refers to whether the old electrical control board has been submitted, whether the quantity submitted meets the requirements, whether the old part label is identifiable, whether the old part has been returned within the specified period, and whether the core components of the old part are intact.

[0043] In this embodiment, the "first access requirement" specifically refers to the maintenance personnel having the authority to requisition the materials, not exceeding the requisition limit, and the old electrical control board having been returned or a deadline for return has been generated. Only when this requirement is met will the system associate the target materials with the warehouse linkage path for new material issuance and old material receipt.

[0044] "Compliance Result 202" in this embodiment specifically refers to the result generated by the system after verifying the actual return of old electrical control boards. The verification content includes whether the old part label corresponds to the current material requisition form, whether the quantity of old parts meets the requirements, whether the old parts were returned within the specified period, and whether the core board is complete.

[0045] In this embodiment, "material label correspondence" specifically refers to the correspondence between the old electrical control board label and the items to be delivered in this material requisition form. If the maintenance personnel return a control board of another model or removed from another piece of equipment, it does not constitute a qualified delivery of old items in this material requisition form.

[0046] In this embodiment, "completion of old work delivery relationship" specifically refers to the relationship between the quantity of old work to be delivered and the quantity of old work actually returned in good condition. For example, if one old work item should be delivered and one old work item is actually returned in good condition, then a completion of old work delivery relationship is formed.

[0047] In this embodiment, "integrity status" specifically refers to whether the core board of the old electrical control board exists, whether the label is identifiable, and whether there is severe damage that prevents it from entering subsequent testing.

[0048] "Installation Replacement and Handover Binding Result 203" in this embodiment specifically refers to the binding result between the confirmation result of the new electrical control board installation and the confirmation result of the old electrical control board removal and handover. This result is used to illustrate that this replacement not only completed the installation of the new component, but also completed the removal and handover of the old component.

[0049] In this embodiment, "Installation Confirmation Result" specifically refers to the installation time, installation location, and installation photos submitted by maintenance personnel after scanning the equipment code and the new electrical control board label via a mobile device; "Return Confirmation Result" specifically refers to the old part label, return time, and warehousing confirmation submitted by maintenance personnel or warehouse personnel after the old control board is removed.

[0050] The "repair and reuse circulation result 204" in this embodiment specifically refers to the subsequent processing result formed after the old electrical control board is returned to the warehouse, through classification and testing, repairability assessment, and repair application. This result can be either entering the repair circulation path or entering the irreparable disposal path.

[0051] In this embodiment, "classification test results" specifically refers to the damaged parts, the extent of damage, and the status of the core board after the testers conduct visual inspection and power-on testing on the old electrical control board.

[0052] In this embodiment, "repairability assessment result" specifically refers to the judgment result formed based on the core board status, damage level, estimated repair time, and post-repair usage requirements.

[0053] In this embodiment, "the first repairable condition" specifically refers to the old electrical control board core card being intact, not reaching the level of being scrapped, and being able to meet at least the requirements for use of non-critical equipment after repair.

[0054] In this embodiment, "reuse level" specifically refers to the usage level of the repaired electrical control board based on the performance test results, such as reuse of the original equipment, reuse of non-critical equipment, disassembly and reuse, or irreparable disposal.

[0055] "Reuse Allocation Result 205" in this embodiment specifically refers to the system allocating the repaired electrical control board to the original usage scenario, non-critical equipment usage scenario, reuse material storage location, or irreparable disposal path according to the reuse level.

[0056] In this invention, unlike intelligent warehouse management systems that only perform inbound and outbound management based on material codes, batch numbers, storage locations, and inventory quantities, this invention establishes a new-old reuse label chain within the material closed-loop management object 100. This new-old reuse label chain is not a simple traceability record of a single material label, but rather a link structure that connects new material labels, old object identifiers to be returned, actually returned old material labels, and repaired reuse material labels into a single closed-loop object.

[0057] Specifically, the new material label indicates the target material for this material requisition and issuance; the old material return object label indicates the object to be returned according to the equipment number, material requisition form number, and new material return rules; the actually returned old material label indicates the old material actually received by the warehouse; and the repaired and reused material label indicates the material that has been repaired and reused and has re-entered the reuse inventory. The system determines whether the new material issuance, old material return, repair disposal, and reuse release are in the same closed-loop chain by comparing the correspondence between the above labels or object identifiers.

[0058] When the system receives a material requisition request, installation confirmation, old material warehousing, repair testing, reuse allocation, or warehousing execution receipt, it does not directly save it as an independent business record. Instead, it first locates the new and old items based on the closed-loop object number, then uses a tag chain, and finally updates the node status of the corresponding link node. The link node status includes untriggered, pending, confirmed, abnormal, written back, and locked states.

[0059] The system generates warehouse action lock control results based on the status of link nodes. For example, if new materials have been issued but the label of the actually returned old materials has not yet matched the identifier of the old materials to be returned, the system will keep the corresponding closed-loop object in a pending old materials lock state and will not release the reusable materials issuance action; if the label of the actually returned old materials does not match the identifier of the old materials to be returned, the system will generate an old materials return abnormal state and prevent the old materials from being a qualified old materials return object for this material requisition form; after the old materials have passed the repair and testing and reached the repair qualified state and formed a reuse allocation result, the system will release the reuse release lock and generate a repaired materials warehousing instruction or a reusable materials issuance instruction.

[0060] Furthermore, after the intelligent warehouse management system returns the warehouse execution receipt, the system generates a write-back verification key based on the closed-loop object number, warehouse action type, material tag, and inventory version number. This key is then used to determine if the current receipt has already been written into the new and old reuse tag chain. If the write-back verification key already exists, the system prevents duplicate write-backs; if it does not exist, the system writes the execution status, actual storage location, actual quantity, and inventory version number to the corresponding link node. If the inventory version number in the warehouse execution receipt is lower than the inventory version number already recorded in the material closed-loop management object 100, the system generates an abnormal compensation status and suspends the closed-loop completion status update.

[0061] By using the aforementioned new and old reuse tag chain, warehousing action lock control, and write-back verification key, this invention transforms the process of exchanging new for old, repairing and reusing old items, and synchronizing smart warehouse inventory into a link node status update process under the same closed-loop object. This avoids the problem that the WMS system cannot determine whether new, old, and reused items belong to the same closed-loop link because it only records the inventory quantity. At the same time, it can reduce the inconsistency between accounts and actual inventory caused by repeated write-back of interfaces, out-of-order receipts, and inventory version conflicts, and improve the consistency and fault tolerance of cross-system inventory synchronization.

[0062] Example 1, referring to Figure 1 As an embodiment of the present invention, a closed-loop material control method based on intelligent warehouse management is provided, comprising: In this embodiment, after workshop maintenance personnel discover a fault in the electrical control board of a certain device, they scan the device code and submit a material requisition request via a mobile terminal. The material requisition request includes the device number, the location of the fault, the model of the required electrical control board, and the quantity requested. After receiving the material requisition request, the system does not immediately process it as a regular material requisition form. Instead, it first generates a closed-loop management object 100 for materials corresponding to the device and the type of control board. In this object, the system establishes a correspondence between "new control board requisition request" and "old control board to be removed and returned".

[0063] After the purchasing staff generates a purchase order based on the demand plan, the supplier submits a delivery reservation through the delivery reservation interface. The warehouse staff scans the barcode of the new electrical control board on the delivery acceptance interface and uploads photos of the delivered goods.

[0064] After acceptance, warehouse staff use a PDA to scan the material labels on the control board and write the batch number, storage location, and warehousing status into the material closed-loop management object 100; after the smart shelf is put on the shelf, the system updates the status of the control board to "available inventory".

[0065] The aforementioned demand, procurement, reservation, acceptance, warehousing, and shelving data are all considered as the front-end content of "full lifecycle flow data." In this embodiment, the full lifecycle flow data specifically refers to the business status data related to the target control panel during the period from the generation of the demand to the formation of inventory after repair and reuse.

[0066] After maintenance personnel initiate a material requisition request, the system reads the new and old requisition rules for this type of control panel and verifies the user's permissions, requisition quota, and historical unrequited records.

[0067] The system forms a material closed-loop constraint state 200 based on the above two types of relationships. If the maintenance personnel have the right to requisition, the quota is not exceeded, and the system has generated a task to return the old control board, then the material closed-loop constraint state 200 is written as "Allow outbound and awaiting old return"; if there are records of unreturned old parts or old parts do not meet the return requirements, then it is written as "Restricted outbound" or "Old return abnormal".

[0068] When the closed-loop constraint status of materials reaches 200, indicating that they can be shipped out, the system sends a new control board shipping task to the intelligent warehouse management system. Maintenance personnel verify their identity and scan the material requisition form at the shipping machine. The shipping machine reads the new control board label and completes the shipping. If the material label read by the shipping machine is inconsistent with the material requisition form, the system generates an abnormal shipping alarm.

[0069] After successful outbound shipment, the warehouse linkage status 300 is recorded as "new parts have been shipped". After the maintenance personnel arrive on site to install the new control board, they scan the equipment code and the new control board label again via mobile terminal and upload installation photos. The system will then write the installation confirmation into the material closed-loop management object 100.

[0070] After the old control board is removed, maintenance personnel submit a removal confirmation on their mobile devices. Warehouse staff scan the old control board label on the scrap material entry interface and complete the entry. The system binds the old control board entry result with the new control board exit result, further updating the warehouse linkage status 300 to "Old part returned to warehouse". If the old control board is detected as repairable, the system initiates a repair application. After the repair is completed and accepted, the warehouse synchronization module re-enters the old control board into the reuse material storage location and writes the inventory synchronization result back to the material closed-loop management object 100, forming the material closed-loop control result 400.

[0071] The 400 result of the closed-loop management of materials is not simply a change in inventory quantity, but reflects whether the issuance, replacement, handover, repair, and reuse of electrical control boards have been completed. When a new part has been issued but the old part has not been issued, the 400 result is recorded as "not closed"; when an old part has been issued but repair has not been completed, it is recorded as "pending repair"; when the old part is repaired and re-enters the reuse inventory, it is recorded as "closed loop completed".

[0072] The timely delivery rate, timely warehousing rate, old item delivery rate, old item delivery completion rate, and repair utilization rate displayed in the system interface can all be generated based on the above node data and used to display the closed-loop execution quality.

[0073] Example 2, refer to Figure 2 Based on Example 1, this embodiment limits the full-process traceability ledger in the material closed-loop management object 100. It adds an implementation method that uses material tags to connect the records of arrival, warehousing, outbound, installation, handover and repair. This solves the technical problem that the same target material forms scattered records in different business interfaces and cannot be continuously traced. It achieves the technical effect that the status of new parts, old parts and repair and reuse status can be verified under the same object.

[0074] In this embodiment, the system first writes the arrival record corresponding to the label when the goods arrive and are accepted; writes the storage location when the goods are put on the shelf; writes the material requisition form when the materials are issued; writes the equipment number when the equipment is installed or replaced; writes the old part label when the old parts are returned; and writes the repair application and repair result when the old parts are repaired and reused.

[0075] In the smart warehousing application interface, supplier arrival appointment, warehouse staff arrival acceptance, photo documentation, physical shelving, and batch identification correspond to different entry points in the end-to-end traceability ledger. After the warehouse staff completes the arrival acceptance, the system writes "Arrival qualified, Photographed, Shelved" to the ledger; if the acceptance fails, it writes "Returned" and the reason for the return. This ledger then continues to handle outbound, installation, and handover data, instead of generating separate, unrelated inventory records.

[0076] Furthermore, when maintenance personnel requisition a new control board through the POS terminal, the system binds the new control board label to the requisition form; when maintenance personnel complete the installation at the equipment site, the mobile terminal binds the equipment number to the new control board label; when the old control board is returned to the warehouse, the warehouse staff scans the old control board label, and the system binds the old control board label to the original requisition form, equipment number, and dismantling record. The entire process traceability ledger simultaneously records the whereabouts of new parts and the origin of old parts.

[0077] Furthermore, when the old control board enters the repair and reuse process, the system continues to write the repair application, repair notification, repair process, performance test results, and reuse status into the same ledger.

[0078] For example, the ledger first shows "The new control board has been issued and installed on equipment A," then it shows "The old control board has been returned to the scrap material warehouse," and finally it shows "The old control board has been repaired and moved to the reuse warehouse." Managers can view the complete flow of the control board from its entry into the material query interface by entering its label. This provides verifiable data for subsequent new and old board issuance, installation and replacement binding, and repair and reuse assessments.

[0079] Example 3, referring to Figures 2-3 Based on Example 1 or Example 2, this embodiment limits the new item issuance and old item return access results 201 and old item return compliance results 202 in the material closed-loop constraint state 200. It adds permission verification, quota verification, old item label verification and old item integrity verification to solve the technical problems of only issuing but not delivering, old items returned do not correspond to the old items to be delivered, and old items that are not fully delivered but are still released from the warehouse. It achieves the technical effect of mutual constraint between new item release and old item return.

[0080] The relationship between new material issuance and old material exchange, as well as the relationship between old material repair and reuse, are represented by a collaborative constraint. This collaborative constraint representation does not simply involve manual approval of issuance applications, old material exchange records, or old material repair applications. Instead, it converts the event data of the same target material at different business nodes into a closed-loop event state vector that can be processed by a computer, and generates a material closed-loop constraint state 200 based on the event state transition relationship.

[0081] Specifically, the system assigns a closed-loop object number to each material closed-loop management object 100, and uses the closed-loop object number as a unified index to write material requisition application events, installation confirmation events, old material return events, scrap material warehousing events, repair application events, performance testing events, reuse allocation events, and inventory synchronization events into the same object record.

[0082] In one implementation, the closed-loop event state vector includes a new material access status bit, an old material return compliance status bit, an installation confirmation status bit, an old material return to warehousing status bit, an old material circulation status bit, a reuse allocation status bit, and an inventory synchronization status bit.

[0083] Each status bit can be represented by a preset enumeration value, such as "not triggered", "pending processing", "passed", "abnormal", and "written back". After receiving new event data, the system does not need to re-traverse all business records. Instead, it locates the corresponding material closed-loop management object 100 based on the closed-loop object number, updates the status bit corresponding to the event, and performs state synthesis on the updated closed-loop event status vector.

[0084] During state synthesis, the system generates material closed-loop constraint state 200 according to the preset event state transition relationship. For example, when the new material access status is "passed" and the old material return compliance status is "passed", the system writes material closed-loop constraint state 200 as "allow warehouse linkage"; when the installation confirmation status is "passed" but the old material return status is still "not triggered" or "pending processing", the system writes material closed-loop constraint state 200 as "pending old material return"; when the repair circulation status is "repairable" and the reuse allocation status is "formed", the system writes material closed-loop constraint state 200 as "allow repaired warehousing or reused warehousing"; when any necessary status is "abnormal", the system writes material closed-loop constraint state 200 as "closed-loop abnormal".

[0085] In this way, the relationships of receiving new materials and exchanging old ones, and repairing and reusing old materials, are not independent business judgments, but are mapped to the same closed-loop event state vector for state synthesis. This processing method reduces repeated cross-table queries and manual comparisons, enabling the system to quickly locate the current closed-loop state of the target material based on the closed-loop object number, and output the executable material closed-loop constraint state 200 to the warehouse synchronization module.

[0086] In this embodiment, the administrator pre-sets the rules for issuing and returning old electrical control boards in the rule configuration interface: for every new control board issued, one old control board should be returned; the old control board should be returned within seven working days of issuance; the core cards of the old control board should be complete and the labels should be identifiable. After this rule is written into the system, it becomes the basis for subsequent outbound access judgment.

[0087] After maintenance personnel submit a material requisition request, the system first reads the material requisition permissions corresponding to the maintenance personnel's account and their monthly requisition quota. If the maintenance personnel do not have the requisition permissions for this type of control panel, the system writes the request into the requisition restriction path; if the quota has been exceeded, the system will not issue a delivery order. Here, "requisition restriction path" specifically means that the material requisition request remains in the approval failed or pending supplementary approval status, and the system does not send a delivery instruction to the smart warehouse.

[0088] If the maintenance personnel's permissions and quotas meet the requirements, the system continues to verify the submission status of scrap materials. In this embodiment, the submission status of scrap materials specifically includes the old control board label, the quantity returned, the return time, and the integrity of the core board.

[0089] When warehouse staff return old parts, they scan the old control board labels with a PDA. The system compares the labels to the old parts to be returned in the current requisition form. If the labels match, the quantity is one piece, the return is within the stipulated period, and the core board is complete, the system generates a qualified return compliance result 202. If the old part labels are inconsistent, the quantity is insufficient, or the core board is missing, the system generates an abnormal return warning path.

[0090] During the exchange of new and old materials, the waste material administrator can generate a list of old materials to be exchanged based on the material requisition form and notify the branch plant's old materials exchange administrator to process it. If the old materials have been exchanged, the system will establish an old materials exchange service record. If the old materials have not been exchanged, the system will establish a supplementary exchange application. If the old materials need to enter the repair process, the system will generate a repair notification form. The system will then generate a statistical analysis table of old materials to be exchanged based on the old materials exchange list, which will be used to display the quantity of old materials to be exchanged, the quantity actually exchanged, and the reasons for any abnormalities.

[0091] For example, after a maintenance worker applies for a new electrical control board, the warehouse manager scans the label on the old control board they submitted. If the system confirms that the old part corresponds to the same equipment replacement task and that the core board is intact, it will write the new / old part exchange approval result 201 as "Allowed to Issue" and the old part exchange compliance result 202 as "Old Part Exchange Completed". If the maintenance worker submits a different model of old control board, although the system can record the old part entering the warehouse, it will not consider it a qualified old part exchange for this requisition form, and the material closed-loop constraint status 200 will remain as "Old Part Exchange Abnormal".

[0092] Example 4, refer to Figures 4-6 Based on any one of the embodiments 1 to 3, this embodiment limits the binding result 203 of installation, replacement and handover of old parts, and adds a binding method between new part installation confirmation, old part removal confirmation and equipment file update. This solves the technical problems of old parts not being recycled after new parts are installed, the source of old parts being unclear and equipment component information not being updated synchronously, and achieves the technical effect of consistent on-site installation results, old part handover results and equipment file status.

[0093] In this embodiment, after the new control board is issued, the system writes the status of the material requisition form to "pending installation"; after the maintenance personnel complete the on-site installation and submit the installation confirmation, the system updates the status to "installed and awaiting acceptance". After the acceptance personnel confirm the installation is qualified on the installation and replacement interface, the system writes the new control board into the equipment file.

[0094] Furthermore, after maintenance personnel remove the old control board, they scan the old control board label on their mobile device and submit a confirmation of removal. When the old control board is returned to the warehouse, the warehouse staff scans the old part label again and completes the confirmation of the scrap material being put into storage. The system uses the same material requisition form and the same equipment number as the association conditions to write the confirmation results of the new control board installation and the old control board return into the same material closed-loop management object 100.

[0095] Furthermore, if the new control board has been installed but the old control board has not been returned, the system will keep the material closed-loop constraint status 200 as "pending old return"; if the old control board has been returned but does not correspond to this equipment replacement task, the system will write the status as "old return abnormal"; if the installation of the new part, the removal and return of the old part, and the warehousing of the old part are all completed, the system will write the status of this replacement as "installation and replacement closed loop completed".

[0096] Taking the replacement of an electrical control board as an example, after maintenance personnel retrieve the new control board from the intelligent warehouse, they scan the equipment code on-site and install the new control board. After the acceptance personnel confirm that the installation is qualified, the system updates the control board information in the equipment file. The maintenance personnel remove the old control board and submit a removal confirmation. After the warehouse staff completes the old part's return to the warehouse, the system binds the installation status of the new part with the return status of the old part. At this point, the management personnel can see in the installation and replacement interface that the corresponding new part has been installed, the old part has been removed and returned, and the old part has been returned to the warehouse, avoiding the problem of on-site installation being completed but the old part remaining unused for a long time.

[0097] Example 5, based on any of Examples 1 to 4, limits the results of repair and reuse circulation 204, reuse allocation 205, and warehouse linkage status 300. It adds a connection method between old parts detection, repairability assessment, repair application, repair task allocation, performance testing, reuse level, and inventory write-back, solving the technical problems of unclear whereabouts of old parts after recycling, lack of tracking of the repair process, and inability of repaired materials to re-enter usable inventory, achieving the technical effect of synchronizing the circulation of repair and reuse with the inventory status of the smart warehouse.

[0098] In this invention, the linked intelligent warehouse refers to the warehouse synchronization module generating a warehouse execution instruction based on the material closed-loop constraint state 200 and sending it to the intelligent warehouse management system through the interface adaptation layer; the write-back refers to the warehouse synchronization module receiving the warehouse execution receipt returned by the intelligent warehouse management system and writing the inventory synchronization result into the material closed-loop management object 100 based on the write-back verification key.

[0099] Specifically, when the material closed-loop constraint state 200 meets the warehousing execution conditions, the warehousing synchronization module generates a warehousing execution instruction corresponding to the target warehousing action. The warehousing execution instruction includes a new material outbound instruction, an old material return-to-warehouse instruction, a repaired material return-to-warehouse instruction, or a reused material outbound instruction. Each warehousing execution instruction includes at least the closed-loop object number, instruction number, material tag, material code, specifications, target warehousing action, target storage area, operator number, and generation time.

[0100] After receiving the warehousing execution instruction, the interface adaptation layer maps the closed-loop object number, material tag, and target warehousing action in this system to task fields that the intelligent warehouse management system can recognize, and then sends them to the intelligent warehouse management system. The intelligent warehouse management system completes the outbound, inbound, storage location allocation, or inventory change according to the warehousing execution instruction, and then returns a warehousing execution receipt. The warehousing execution receipt includes at least the instruction number, execution status, actual executed quantity, actual storage location, quantity before inventory change, quantity after inventory change, inventory version number, exception code, and exception description.

[0101] After receiving the warehouse execution receipt, the warehouse synchronization module combines the instruction number, closed-loop object number, material tag, and inventory version number into a write-back verification key, and queries whether the same write-back verification key already exists in the material closed-loop management object 100.

[0102] If no identical write-back verification key exists, the system will write the execution status, actual storage location, actual execution quantity, and inventory version number from the warehouse execution receipt into the material closed-loop management object 100, and simultaneously update the warehouse linkage status 300; if the same write-back verification key already exists, the system will determine that the receipt is a duplicate receipt and will no longer perform inventory status changes.

[0103] When the new material outbound receipt, the old material return receipt, and the repaired material return receipt are all effectively written back, the system updates the material closed-loop management result 400 to the closed-loop completed status; when the new material outbound receipt has been written back but the old material return receipt has not been written back, the system updates the material closed-loop management result 400 to the unclosed status; when the warehouse execution receipt contains an abnormal code or an inventory version number conflict, the system updates the material closed-loop management result 400 to the warehouse abnormal status or inventory conflict status.

[0104] After the old control board is received as scrap material, the system reads its material tag and retrieves the material requisition form, equipment number, handover status, and installation / replacement record from the material closed-loop management object 100. Inspectors perform a visual inspection and power-on test on the old control board, generating a classification inspection result. In this embodiment, the classification inspection result specifically includes the damaged parts, the degree of damage, and the status of the core board. If the inspection result shows that the core board is intact but the wiring terminals are damaged, the system writes the old control board to a repairable assessment status.

[0105] Furthermore, based on the core board status, damage level, estimated repair time, and post-repair usage requirements, the system or maintenance personnel determine whether the repaired board can meet the usage requirements of non-critical equipment. If this condition is met, the system will associate the old control board with the repair workflow; otherwise, the system will associate it with the unrepairable disposal path.

[0106] Once the repair process begins, the designated personnel initiate a repair application on the repair and reuse interface. After approval by the supervisor, repair personnel are assigned to the application. The repair personnel then record the repair process on the terminal, such as replacing wiring terminals, cleaning contacts, and conducting power-on tests.

[0107] After the repair is completed, the acceptance personnel submit the performance test results. The system determines the reuse level based on the test results. If the repaired control board can be used in the original equipment, the system determines the original scenario reuse level; if it can only be used in non-critical equipment, the system determines the non-core scenario reuse level; if it does not have the value of the whole component, the system determines the disassembly and reuse or irreparable disposal result.

[0108] Furthermore, for old control boards that are reused in non-core scenarios, the system sends a repair and warehousing task to the smart warehouse, which then allocates a storage location for the reused materials and returns an warehousing confirmation. For old control boards that cannot be repaired, the system generates a disposal and outbound task and writes back the inventory write-off status. The above warehousing confirmation or disposal results form a warehouse linkage status 300, which is further written back as a material closed-loop management result 400.

[0109] For example, after testing, the core board of an old electrical control board is confirmed to be intact. The repair personnel complete the replacement of the wiring terminals and pass the power-on test. The system determines that the control board can be used for non-critical equipment and assigns it to the reuse material storage location. After the smart warehouse returns the storage location information, the system updates the status of the old control board to "reusable after repair". If other departments apply for the reuse of the control board in the future, the system can match and retrieve it from the reuse storage location. Through this process, the old control board no longer remains in the state of scrap material, but is re-entered into the usable inventory after testing, repair, acceptance and inventory write-back.

[0110] Through the aforementioned instruction generation, interface mapping, receipt reception, and idempotent write-back mechanism, this invention does not simply transfer warehousing business rules to a computer for execution. Instead, it establishes a cross-system inventory synchronization mechanism using closed-loop object numbers, event state vectors, warehousing execution instructions, warehousing execution receipts, and write-back verification keys. This reduces the risks of duplicate write-backs, inventory version conflicts, and cross-system state inconsistencies, and improves data consistency and interface fault tolerance between the intelligent warehouse and the material closed-loop management object.

[0111] Example 6 is an embodiment of the present invention, which provides a closed-loop material control system based on intelligent warehouse management, including an object filing module, a constraint representation module, and a warehouse synchronization module.

[0112] The object filing module forms 100 objects for closed-loop management of materials based on the full life cycle circulation data and material label information of the target materials. It writes the object correspondence formed by the target materials from the triggering of new demand, through the return of old materials and the disposal of old materials to the reuse of inventory into the full-process traceability ledger.

[0113] The constraint representation module forms a material closed-loop constraint state 200 based on the material closed-loop management object 100, and associates the new issuance and old exchange access results 201, old exchange compliance results 202, installation, replacement and old exchange binding results 203, repair and reuse circulation results 204, and reuse allocation results 205 with the closed-loop object correspondence of the target material.

[0114] The warehouse synchronization module forms a warehouse linkage state 300 based on the material closed-loop constraint state 200, and writes back the material closed-loop management object 100 after synchronizing and associating the new material outbound, the scrap material inbound, and the inventory changes of the reused material with the inventory data of the intelligent warehouse management system, thus forming the material closed-loop control result 400.
