Description

Technical Field

[0001] This invention relates to the field of stacked material management, and in particular to an intelligent collaborative management system for materials in the main network stacking area. Background Technology

[0002] Spare parts and components for the main network are typically carried in containers and stored in a three-dimensional stacking area during warehousing. These materials include circuit breakers, surge arresters, disconnect switches, cable accessories, and instrument transformers, and are characterized by their large size, high weight, high frequency of hoisting, and fast warehouse turnover. To support high-frequency operations such as warehousing, outbound, and inventory, the task instructions of the main network material storage management system (WMS) interface with the main network material storage management system and the scanning and transmission of handheld PDAs need to be linked on-site. This should be combined with container specifications, three-dimensional coding of warehouse locations, and stacking height constraints to form a standardized material management process for the main network stacking area.

[0003] However, in the existing mainnet stack area management, the functional partition boundaries and partition codes, job permissions, and path constraints lack unified and solidified rules, resulting in insufficient verification of task assignment landing points and job return attribution, which easily leads to process loss of control caused by cross-regional operations and inconsistent paths.

[0004] Meanwhile, when there are no unified adaptation rules for container specifications, three-dimensional coding of storage locations, and stacking height constraints, storage location allocation and stacking layer numbers are affected by human experience, which may lead to problems such as excessive stacking height, unclear storage location occupancy, accounting discrepancies, and safety risks. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent collaborative management system for materials in the main network stacking area. This system aims to solidify the functional zoning model, unique zoning codes, and work permission sets of the main network stacking area by constructing a zoning label linkage module, a container stacking rule module, an empty box warehousing and shelving module, an warehousing binding and shelving module, an outbound unbinding and return module, and an inventory difference closed-loop module. Furthermore, it introduces a container specification parameter table, a three-dimensional code for storage locations, and stacking height constraints into the task execution chain to achieve closed-loop control of specified storage location code feedback, shelving lock closure verification, and status write-back. Further, through the reconstruction of material container binding / unbinding records and surplus material return binding, combined with the consistency verification of daily information inventory and physical inventory, and the mechanism for sealing and reviewing abnormal storage locations, it suppresses long-term storage location occupancy and data difference diffusion, thereby improving the traceability and consistency of main network spare parts warehousing and inventory.

[0006] Therefore, this application provides an intelligent collaborative management system for materials in the main network stacking area, including the following modules: The partition label linkage module is used to configure the functional partition model of the main network stacking area and bind the operation constraints, configure the main network material master data and solidify the main network material mapping table, initialize the bidirectional communication link between the PDA handheld terminal and the main network material warehouse management system (WMS), and initialize the operation task distribution link between the main network material warehouse management system (WMS) and the gantry crane equipment.

[0007] The container stacking rules module is used to configure the three-dimensional container resource pool and write it into the container specification parameter table. It generates fixed rules for loading main network materials based on the main network material master data, and generates three-dimensional codes for storage locations based on the container specification parameter table and fixes stacking height constraints.

[0008] The empty container receiving and shelving module is used to configure the arrival event of empty containers, generate a specified storage location code based on the container specification parameter table, complete the stack lock closure verification, and set the write-back empty container receiving task completion status.

[0009] The warehouse entry binding and shelving module is used to configure the main network material arrival verification record, retrieve empty containers, generate internal displacement event records of empty containers, execute the main network material loading and fixing rules, and write back the main network material entry task results.

[0010] The Outbound Unbinding and Return-to-Warehouse module is used to configure the main network material outbound task, set the gantry crane operation sequence, execute the internal relocation and sorting of outbound containers, execute the return-to-warehouse binding and reconstruction of surplus materials, and set the original warehouse location return confirmation event and write back the main network material outbound task results.

[0011] The inventory discrepancy closed-loop module is used to configure inventory tasks, set inventory path sequences and inventory operation batch numbers, perform daily information inventory, generate daily information inventory discrepancy records, and perform physical inventory consistency verification.

[0012] In some specific implementations, the partition label linkage module specifically includes: Configure the main network stacking area functional partition model and bind the operation constraints, configure the main network material master data, and solidify the main network material mapping table.

[0013] Initialize the interface between the main network material storage management system (WMS) and the upper-level business system, and the linkage link between the main network material storage management system (WMS).

[0014] In some specific implementations, the container stacking rules module specifically includes: Configure the three-dimensional container resource pool and write it into the container specification parameter table, and generate fixed rules for loading main network materials based on the main network material master data.

[0015] Generate a 3D code for the storage location based on the container specification parameter table and solidify the stacking height constraint.

[0016] The mainnet Material Warehousing Management System (WMS) establishes storage location configuration records and generates storage location codes in the three-dimensional stacked storage area. The storage location code consists of a row number field, a column number field, and a layer number field. The row number field is set to a value range of 01 to 40, the column number field is set to a value range of 01 to 02, and the layer number field is set to a value range of 01 to 04. The number of storage location configuration records is set to 80 storage location codes, corresponding to a layout relationship of two container storage locations per row.

[0017] The mainnet Material Warehousing Management System (WMS) establishes stacking height constraint rule records and associates them with the container specification parameter table. The stacking layer threshold for full-height open-top containers is set to 2 layers, and the stacking layer threshold for half-height open-top containers is set to 4 layers. The WMS also establishes mixed stacking height constraint rule records. These records use the full-height open-top container height of 2600mm as the single-layer height benchmark and set the total mixed stacking height threshold to 5200mm. When the cumulative stacking height of the same storage location code exceeds 5200mm, the WMS generates a stacking height over-limit event and marks the corresponding storage location code as unassignable.

[0018] In some specific implementations, the empty box receiving and shelving module specifically includes: Configure an empty container arrival event, generate a specified storage location code based on the container specification parameter table, and complete the stack lock closure verification.

[0019] Set the completion status of the write-back empty container storage task.

[0020] After warehouse staff complete the shelving of empty containers in the automated stacking storage area, they generate a container arrival confirmation event on their handheld PDA. The container arrival confirmation event includes a unique task number, a unique partition code, a specified storage location code, a container barcode, an arrival timestamp, and a lock closure verification result identifier. After receiving the container arrival confirmation event, the main network material storage management system (WMS) performs field integrity verification and writes it into the task process record.

[0021] Warehouse managers can trigger the "Complete Inbound Task" button on a handheld PDA. This button triggers a task completion status feedback, which includes a unique task number, completion timestamp, executor account, and a list of abnormal events. The time interval between the container arrival confirmation event timestamp and the inbound task completion button trigger timestamp is set to 60 seconds to suppress the drift between inventory and physical inventory caused by items being shelved but not yet written back.

[0022] The material flow path for empty containers entering the warehouse is fixed into two path sequences in the main network material storage management system (WMS). The first path sequence is from the inbound / outbound buffer and sorting area to the automated stacking storage area, and the second path sequence is from the loading / unloading area to the automated stacking storage area. The main network material storage management system (WMS) performs path constraint rule consistency verification on the two path sequences.

[0023] In some specific implementations, the warehousing and listing module is bound together, specifically including: Generate a main network material arrival verification record, retrieve empty container, and generate an internal displacement event record for the empty container.

[0024] Execute the mainnet material loading fixed rules and write back the mainnet material warehousing task results.

[0025] In some specific implementations, the outbound unbinding and return module specifically includes: Configure the main network material outbound task and set the gantry crane operation sequence to execute the internal relocation and sorting of outbound containers.

[0026] Perform the re-binding and reconstruction of surplus material return to the warehouse, and set the original warehouse location return confirmation event and write back the main network material outbound task results.

[0027] In some specific implementations, the inventory discrepancy closed-loop module specifically includes: Configure inventory tasks, set inventory path sequences and inventory batch numbers, execute daily information inventory, and generate daily information inventory discrepancy records.

[0028] Perform a physical inventory consistency check.

[0029] When the task type identifier is a physical inventory identifier, the mainnet Material Warehousing Management System (WMS) generates a bound material list record based on the material container binding record table and the surplus material return binding record table. The bound material list record includes a unique task number, container code, storage location code, material barcode list field, and bound quantity value. The bound quantity value is the number of entries in the material barcode list field.

[0030] Warehouse management personnel perform unpacking and inventory checks on the coded containers in the inbound / outbound buffer and sorting areas. Using handheld PDAs, they scan the material barcodes to create a physical inventory record. This record includes a unique task number, container code, storage location code, material barcode list field, inventory timestamp, and on-site quantity value. The material barcode scanning upload delay threshold is set to 10 seconds.

[0031] In summary, the intelligent collaborative management system for mainnet stacking area materials provided in this application divides the mainnet stacking area into a fixed number of functional zones and generates unique zone codes and sets of work permissions, based on tasks, containers, storage locations, and event write-back. Path constraints are used to verify the work landing point and the attribution of the returned data, reducing process control loss caused by inconsistencies between zones and paths. Simultaneously, based on the three-dimensional container resource pool and container specification parameter table, three-dimensional codes for storage locations are generated and stacking height constraints are fixed. Combined with the closed loop of empty container shelving, material loading and binding, outbound unbinding, and surplus material return, a synchronous write-back of storage location occupancy, loading status, and task results is formed, reducing the risk of data drift. Attached Figure Description

[0032] Figure 1 This is an overall framework diagram of a main network stacking area material intelligent collaborative management system provided in an embodiment of this application. Detailed Implementation

[0033] Please refer to Figure 1 This illustrates the flow of one embodiment of a mainnet stacking area material intelligent collaborative management system according to the present disclosure.

[0034] like Figure 1 As shown, a smart collaborative management system for materials in a main network stacking area includes the following modules: The partition label linkage module is used to configure the functional partition model of the main network stacking area and bind the operation constraints, configure the main network material master data and solidify the main network material mapping table, initialize the bidirectional communication link between the PDA handheld terminal and the main network material warehouse management system (WMS), and initialize the operation task distribution link between the main network material warehouse management system (WMS) and the gantry crane equipment.

[0035] The container stacking rules module is used to configure the three-dimensional container resource pool and write it into the container specification parameter table. It generates fixed rules for loading main network materials based on the main network material master data, and generates three-dimensional codes for storage locations based on the container specification parameter table and fixes stacking height constraints.

[0036] The empty container receiving and shelving module is used to configure the arrival event of empty containers, generate a specified storage location code based on the container specification parameter table, complete the stack lock closure verification, and set the write-back empty container receiving task completion status.

[0037] The warehouse entry binding and shelving module is used to configure the main network material arrival verification record, retrieve empty containers, generate internal displacement event records of empty containers, execute the main network material loading and fixing rules, and write back the main network material entry task results.

[0038] The Outbound Unbinding and Return-to-Warehouse module is used to configure the main network material outbound task, set the gantry crane operation sequence, execute the internal relocation and sorting of outbound containers, execute the return-to-warehouse binding and reconstruction of surplus materials, and set the original warehouse location return confirmation event and write back the main network material outbound task results.

[0039] The inventory discrepancy closed-loop module is used to configure inventory tasks, set inventory path sequences and inventory operation batch numbers, perform daily information inventory, generate daily information inventory discrepancy records, and perform physical inventory consistency verification.

[0040] In some specific implementations, the partition label linkage module specifically includes: Configure the main network stacking area functional partition model and bind the operation constraints, configure the main network material master data, and solidify the main network material mapping table.

[0041] A functional zoning model for the main network stacking area is established. Based on the warehouse layout, the main network stacking area is divided into inbound / outbound buffer and sorting area, loading and unloading area, three-dimensional stacking storage area, pedestrian passage and large component flat area. The number of functional zoning areas is set to 5 and kept fixed. The names and boundaries of the functional zoning areas are formed into an editable topology layer in the main network material storage management system (WMS) for the partition landing point verification of task issuance and the partition ownership verification of operation feedback.

[0042] The mainnet material storage management system (WMS) generates unique partition codes for each of the five functional partitions. The unique partition codes use a 12-digit alphanumeric encoding and are written into the partition primary key field. The unique partition codes correspond to the functional partition names.

[0043] The mainnet material storage management system (WMS) generates a set of operation permissions for each of the five functional areas. The set of operation permissions includes inbound scanning permission, outbound verification permission, inventory execution permission, storage location confirmation permission, and exception reporting permission. The set of operation permissions is bound to the identity account of the warehouse management personnel and synchronized to the local permission cache of the handheld PDA.

[0044] The mainnet material storage management system (WMS) establishes path constraint rules for task issuance and operation feedback. The path constraint rules are fixed in the form of starting functional partition, target functional partition, and allowed passage functional partition sequence. The path constraint rules set the passage sequence from the inbound / outbound cache and sorting area to the three-dimensional stacked storage area as a unique sequence, and set the passage sequence from the loading / unloading area to the inbound / outbound cache and sorting area as a unique sequence.

[0045] When the functional partition sequence carried in the job feedback is inconsistent with the path constraint rules, the mainnet material storage management system (WMS) generates a path violation event and marks the path violation event as a level 2 anomaly. The level 2 anomaly triggers a pop-up window on the handheld PDA for review and requires the submission of a review conclusion within 30 seconds. If the review conclusion is not submitted within 30 seconds, the mainnet material storage management system (WMS) sets the status of the corresponding task to paused pending review.

[0046] Establish master data for main network materials. The master data for main network materials should include at least the main network material identifier, specifications, weight class, precision level, compatibility and mounting relationship, operation frequency, and safety distance. It should also include indoor storage requirements, hoisting and unloading requirements, center of gravity level, and fixing method level, which will be used to provide data input for the constraints of the stacking adaptation rule base.

[0047] The indoor storage requirement label uses a binary enumeration, with values ​​limited to indoor and non-indoor storage. The hoisting and unloading requirement label uses a binary enumeration, with values ​​limited to hoisting and unloading and non-hoisting and unloading. The material size grade label uses a three-level enumeration, with values ​​limited to size grade A, size grade B, and size grade C. The maximum external dimensions corresponding to size grade A are no greater than 2000mm×1500mm×1800mm, the maximum external dimensions corresponding to size grade B are greater than 2000mm×1500mm×1800mm but no greater than 4000mm×2500mm×2500mm, and the maximum external dimensions corresponding to size grade C are greater than 4000mm×2500mm×2500mm.

[0048] The center of gravity level label uses a three-level enumeration, with values ​​limited to center of gravity level I, center of gravity level II, and center of gravity level III. Center of gravity level I corresponds to a center of gravity height of no more than 0.6m, center of gravity level II corresponds to a center of gravity height of more than 0.6m and no more than 1.2m, and center of gravity level III corresponds to a center of gravity height of more than 1.2m. The fixation method level label also uses a three-level enumeration, with values ​​limited to fixation method level 1, fixation method level 2, and fixation method level 3. Fixation method level 1 corresponds to two-point fixation, fixation method level 2 corresponds to four-point fixation, and fixation method level 3 corresponds to figure-eight cross fixation.

[0049] The main network spare parts and components include circuit breakers, surge arresters, disconnect switches, cable accessories, and instrument transformers. Circuit breakers, surge arresters, disconnect switches, cable accessories, and instrument transformers are uniformly included in the main network material master data mapping table. The main network material master data mapping table is fixed in the form of material name, tag combination, stacking rule number, and warehouse location allocation constraint number, and is used for subsequent stacking rule matching and warehouse location allocation.

[0050] The main network material storage management system (WMS) sets a version number field in the main network material master data mapping table. The version number field adopts the YYYYMMDD-serial number format and is synchronized with the upper-level system. When the version number field changes, the main network material storage management system (WMS) will push the changed main network material master data mapping table to the handheld PDA within 10 seconds and complete the local overwrite.

[0051] Initialize the bidirectional communication link between the PDA handheld terminal and the main network material storage management system (WMS), and initialize the task distribution link between the main network material storage management system (WMS) and the overhead crane equipment.

[0052] The system linkage is initialized, and the main network material storage management system (WMS) uniformly accepts inbound tasks, outbound tasks, transfer tasks, and inventory tasks. The task acceptance process writes the task number and forms an association record of task, material, container, and stacking position.

[0053] The mainnet material storage management system (WMS) and the PDA handheld terminal execute task issuance and result feedback. The mainnet material storage management system (WMS) issues operation instructions to the PDA handheld terminal and receives the barcode binding result, unpalletization verification result and status update result. The feedback result is written into the task result field and triggers the three-dimensional coordinate model refresh.

[0054] After receiving the operation completion status, the main network material storage management system (WMS) updates the material status, container status, and stacking position occupancy status and generates a full-process traceability record. The full-process traceability record includes the task number, operation timestamp, executor identifier, material identifier, container code, stacking position three-dimensional coordinates, and operation result identifier.

[0055] After successful task synchronization, the mainnet Material Storage Management System (WMS) distributes inbound, outbound, and inventory tasks to the handheld PDAs of warehouse management personnel. The handheld PDAs filter out unexecutable tasks based on the set of job permissions and maintain consistent task list sorting. During execution, the handheld PDAs transmit scan events and task completion status. Each scan event includes a unique task number, unique partition code, storage location code, material barcode, and scan timestamp. The scan timestamp accuracy is set to milliseconds.

[0056] The mainnet material storage management system (WMS) performs field integrity checks on scan events. If a field is missing, a level 1 exception is triggered, requiring a rescan to complete the field within 15 seconds. If the field is not completed within 15 seconds, the corresponding task status is set to execution interruption.

[0057] After receiving the task completion status, the mainnet Material Warehousing Management System (WMS) writes the task result back to the superior system to form a closed loop. The task result is fixed and includes a unique task number, completion timestamp, executor account, and a list of abnormal events. The mainnet Material Warehousing Management System (WMS) sets the write-back response timeout threshold to 8 seconds. Write-back timeout triggers a write-back retry, and the maximum number of retries is set to 5. After successful write-back, the superior system write-back receipt number to the task archive field. After the task archive field is filled with a completion marker, the task status is set to closed loop completion.

[0058] In some specific implementations, the container stacking rules module specifically includes: Configure the three-dimensional container resource pool and write it into the container specification parameter table, and generate fixed rules for loading main network materials based on the main network material master data.

[0059] The mainnet Material Storage Management System (WMS) receives container acceptance information and establishes a three-dimensional container resource pool. The container acceptance information includes the container's structural type, external dimensions, load-bearing capacity, foundation structure, and intermediate stacking lock structure. The three-dimensional container resource pool includes 20ft semi-high open-top containers, 20ft full-high open-top containers, 30ft semi-high open-top containers, and 30ft full-high open-top containers.

[0060] The mainnet material storage management system (WMS) establishes a container specification parameter table and writes it into the container specification record.

[0061] The load-bearing capacity threshold of the 20ft semi-high open-top container is set at 5t, and the container's external dimensions are set at 6100mm×2500mm×1300mm. The container structure includes a foot structure and an intermediate stacking lock structure.

[0062] The load-bearing capacity threshold of the 20ft full-height open-top container is set at 5t. The container's external dimensions are set at 6100mm×2500mm×2600mm. The container structure includes a foot structure and an intermediate stacking lock structure.

[0063] The load-bearing capacity threshold of the 30ft semi-high open-top container is set at 5t, and the container's external dimensions are set at 9200mm×2500mm×1300mm. The container structure includes a foot structure and an intermediate stacking lock structure.

[0064] The load-bearing capacity threshold of the 30ft full-height open-top container is set at 5t. The container's external dimensions are set at 9200mm×2500mm×2600mm. The container structure includes a foot structure and an intermediate stacking lock structure.

[0065] The mainnet material storage management system (WMS) generates a container code for each container in the automated container resource pool and writes it into the container asset record. Warehouse managers print the container code as a container barcode and affix it to the outer surface of the container. The container barcode serves as the container identification field in the handheld PDA scanning event.

[0066] The mainnet Material Storage Management System (WMS) establishes a loading and securing material list, which includes straps, wooden strips, and anti-slip mats. After warehouse managers complete the entry registration of straps, wooden strips, and anti-slip mats, they generate a loading and securing material availability record. This availability record serves as the activation condition for the mainnet material loading and securing rules.

[0067] The main network material storage management system (WMS) reads the hoisting and unloading requirement tags and fixing method level tags from the main network material master data mapping table, generates a main network material loading and fixing rule record, and configures open-top container as the loading container structure for main network spare parts materials with the hoisting and unloading requirement tag as hoisting and unloading, in order to meet the hoisting and unloading path of the gantry crane.

[0068] The mainnet material storage management system (WMS) configures the corresponding strapping fixing methods for the fixing method level labels: Fixing method level 1 corresponds to two-point fixing, with the number of straps set to 2, the strap pretension threshold set to 1.5kN, and the fixing point positions set to the two diagonal points of the hook ring on the inner wall of the container; Fixing method level 2 corresponds to four-point fixing, with the number of straps set to 4, the strap pretension threshold set to 1.5kN, and the fixing point positions set to the four corners of the hook ring on the inner wall of the container; Fixing method level 3 corresponds to figure-eight cross fixing, with the number of straps set to 4, the strap pretension threshold set to 2.0kN, the four straps forming two sets of figure-eight cross strap paths and connecting to the hook ring on the inner wall of the container respectively; wooden strips are used to form the bottom support strip of the material and limit lateral displacement; anti-slip mats are laid between the bottom surface of the material and the bottom support surface of the container and limit the sliding tendency.

[0069] The mainnet Material Storage Management System (WMS) establishes container specification adaptation rules based on material size and center of gravity level labels. These rules calculate the adaptation ratio for 20ft semi-height open-top containers, 20ft full-height open-top containers, 30ft semi-height open-top containers, and 30ft full-height open-top containers, and select the container specification record with the lowest adaptation ratio. The adaptation ratio is defined as follows: in, , , These correspond to the material length, material width, and material height, respectively. The material length, material width, and material height are obtained after being written into the material master data record. , , These correspond to the effective loading length, effective loading width, and effective loading height of the container, respectively. The effective loading length, effective loading width, and effective loading height of the container are obtained by warehouse management personnel after measuring the internal loading space of the container and recording it in the container specification parameter table.

[0070] The mainnet material storage management system (WMS) sets the adaptation ratio threshold to 1.00. When the adaptation ratio is not greater than 1.00, it is determined that the container specifications match the material dimensions and the container specifications are recorded in the loading task parameters. When the adaptation ratio is greater than 1.00, a container specification mismatch event is generated and the container specification reselection process is triggered.

[0071] The mainnet material storage management system (WMS) establishes loading sequence rule records. The loading sequence rule records are sorted based on the material quality parameters in the material master data records and generate loading sequence sequences. The first material in the loading sequence is placed on the bottom support surface of the container, and the last material in the loading sequence is placed on the upper layer of the loading space. This is used to reduce the risk of a high center of gravity in the three-dimensional stacking state.

[0072] Generate a 3D code for the storage location based on the container specification parameter table and solidify the stacking height constraint.

[0073] The mainnet Material Warehousing Management System (WMS) establishes storage location configuration records and generates storage location codes in the three-dimensional stacked storage area. The storage location code consists of a row number field, a column number field, and a layer number field. The row number field is set to a value range of 01 to 40, the column number field is set to a value range of 01 to 02, and the layer number field is set to a value range of 01 to 04. The number of storage location configuration records is set to 80 storage location codes, corresponding to a layout relationship of two container storage locations per row.

[0074] The mainnet Material Warehousing Management System (WMS) establishes stacking height constraint rule records and associates them with the container specification parameter table. The stacking layer threshold for full-height open-top containers is set to 2 layers, and the stacking layer threshold for half-height open-top containers is set to 4 layers. The WMS also establishes mixed stacking height constraint rule records. These records use the full-height open-top container height of 2600mm as the single-layer height benchmark and set the total mixed stacking height threshold to 5200mm. When the cumulative stacking height of the same storage location code exceeds 5200mm, the WMS generates a stacking height over-limit event and marks the corresponding storage location code as unassignable.

[0075] The mainnet Material Warehousing Management System (WMS) establishes a rule record for verifying the closure status of intermediate stacking locks. The lock closure confirmation time threshold for this rule record is set to 20 seconds. If the lock closure confirmation is not completed within 20 seconds, the WMS will mark the corresponding storage location code as paused and push a lock closure verification prompt message to the handheld PDA. The lock closure verification prompt message includes the container code, storage location code, and stacking height constraint rule record number.

[0076] In some specific implementations, the empty box receiving and shelving module specifically includes: Configure an empty container arrival event, generate a specified storage location code based on the container specification parameter table, and complete the stack lock closure verification.

[0077] The mainnet material storage management system (WMS) receives empty container arrival information through its upper-level business system interface and generates an empty container warehousing task. The empty container warehousing task, carrying a unique task number, is synchronized to the mainnet material storage management system (WMS). The mainnet material storage management system (WMS) then distributes the empty container warehousing task to the handheld PDAs of warehouse management personnel.

[0078] The mainnet material storage management system (WMS) sets up a first receiving zone for empty containers in the inbound / outbound cache and sorting area, and a second receiving zone for empty containers in the loading / unloading area. The mainnet material storage management system (WMS) configures receiving temporary storage location codes for the inbound / outbound cache and sorting area and the loading / unloading area, respectively. The receiving temporary storage location codes are written into the storage location configuration record and establish a corresponding relationship with the unique zone code.

[0079] When warehouse staff receive information about the arrival of empty containers in the inbound / outbound buffer and sorting area, they select an empty container inbound task on their handheld PDA and initiate an empty container arrival event registration. The empty container arrival event registration includes a unique task number, a unique partition code, a receiving temporary storage location code, and an arrival timestamp.

[0080] When warehouse managers receive information about the arrival of empty containers in the loading and unloading area, they select the empty container receiving task on their handheld PDA and initiate an empty container arrival event registration. The empty container arrival event registration includes a unique task number, a unique partition code, a receiving temporary storage location code, and an arrival timestamp.

[0081] After obtaining the container barcode affixed to the outer surface of the empty container, the warehouse manager uses a handheld PDA to scan the container barcode and generate an empty container entry scan event record.

[0082] The empty container receiving scan event record includes a unique task number, a unique partition code, a receiving temporary storage location code, a container barcode, and a scan timestamp. The container barcode is written into the material barcode field and a corresponding relationship is established with the container code in the container asset record.

[0083] After the handheld PDA completes the scanning timestamp generation, it uploads the empty container entry scanning event record to the main network material storage management system (WMS). The handheld PDA scanning upload delay threshold is set to 10 seconds.

[0084] After receiving the empty container inbound scan event record, the mainnet material storage management system (WMS) reads the container code from the container asset record, reads the container's external dimensions from the container specification parameter table and determines the container specification type identifier. The mainnet material storage management system (WMS) reads the storage location code occupancy status identifier from the storage location configuration record and forms a set of available storage locations. The storage location code occupancy status identifier is limited to the values ​​of allocable status and unallocable status.

[0085] The mainnet Warehouse Management System (WMS) performs a designated storage location selection calculation on the available storage locations. This calculation calculates a cost function for each candidate storage location code and selects the candidate storage location code with the minimum cost function as the designated storage location code. The cost function is defined as follows: In the formula, This is a value indicating the occupancy status of the storage location code. A value of 0 indicates an allocable location, while a value of 1 indicates an unallocable location. The current cumulative stack height is the encoding value for the candidate library location.
