Description

Technical Field

[0001] The embodiments disclosed herein relate to the fields of warehouse control technology and computer technology, and specifically to a method and apparatus for goods entry and exit from a warehouse control system. Background Technology

[0002] Warehouse control systems are a crucial component of smart warehousing projects. Currently, to further improve warehousing efficiency, multi-level shuttle cars are typically introduced for warehouse control. These cars eliminate the need for independent lifting equipment, allowing operations across floors and aisles. By integrating vertical and horizontal movement, they reduce equipment coordination time and increase task throughput.

[0003] However, multi-level shuttles are highly complex. To adapt to the operating environment of multi-level shuttles, it is necessary not only to modify the warehouse design and re-plan the warehouse, requiring more cost investment, but also to be prone to various difficult-to-repair fault risks during high-frequency operation (such as steering mechanism jamming, drive wheel power imbalance, lifting system jamming, etc.), which can lead to blockage of the conveying channel (or conveying area), thereby increasing equipment maintenance costs and reducing warehouse efficiency. Summary of the Invention

[0004] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] Some embodiments of this disclosure propose methods and apparatus for goods entry and exit in warehouse control systems to solve the technical problems mentioned in the background section above.

[0006] In a first aspect, some embodiments of this disclosure provide a method for goods inbound and outbound operations applied to a warehouse control system. The method includes: in response to receiving a goods inbound order from a warehouse management system, generating a corresponding goods inbound task, and adding the goods inbound task to an inbound task queue to obtain an added task queue, wherein the warehouse control system is communicatively connected to the warehouse management system; controlling a barcode scanner to scan and identify a goods box delivered to a scanning location to obtain a corresponding goods box number; performing the following inbound steps on the goods box number: matching the goods box number with the goods inbound tasks in the added task queue to obtain a matched inbound task, wherein the matched inbound task includes the goods box placement layer number and the goods box storage location number; in response to confirming... If the number of layers for placing the aforementioned cargo boxes is greater than 1, the matching warehousing task is split into a hoist task and a shuttle task. Using the shuttle task, the handling equipment is controlled to move the cargo boxes corresponding to the aforementioned cargo box numbers to the hoist waiting area. Based on preset priority criteria, the hoist task is prioritized, and according to the prioritized tasks, it is added to the hoist loading task queue. In response to the activation of the hoist loading task corresponding to the aforementioned hoist task in the hoist loading task queue, the cargo boxes are transported from the hoist waiting area to the handling area. According to the number of layers and cargo box location numbers included in the matching warehousing task, the hoist and the second shuttle are used to warehouse the aforementioned cargo boxes.

[0007] Secondly, some embodiments of this disclosure provide a goods inbound / outbound device applied to a warehouse control system. The device includes: a generation unit configured to generate a corresponding goods inbound task in response to receiving a goods inbound order from a warehouse management system, and to add the goods inbound task to an inbound task queue to obtain an added task queue, wherein the warehouse control system is communicatively connected to the warehouse management system; a scanning and identification unit configured to control a barcode scanner to scan and identify a goods box delivered to the scanning location to obtain a corresponding goods box number; and a goods inbound unit configured to perform the following inbound steps on the goods box number: matching the goods box number with the goods inbound tasks in the added task queue to obtain a matched inbound task, wherein the matched inbound task includes placing the goods box... The system sets the layer number and cargo box location number; in response to determining that the cargo box placement layer number is greater than 1, it splits the matched warehousing task into a task to generate a hoist task and a shuttle task; through the shuttle task, it controls the handling equipment to move the cargo box corresponding to the cargo box number to the hoist waiting area; according to the preset priority division conditions, it divides the hoist task into task priorities, and adds the hoist task to the hoist loading task queue according to the divided task priorities; in response to the hoist loading task corresponding to the hoist task in the hoist loading task queue starting, it transports the cargo box from the hoist waiting area to the handling area; according to the cargo box placement layer number and cargo box location number included in the matched warehousing task, it uses the hoist and the second shuttle to perform cargo warehousing for the cargo box.

[0008] Thirdly, some embodiments of this disclosure provide an electronic device, including: one or more processors; and a storage device having one or more programs stored thereon, wherein when the one or more programs are executed by the one or more processors, the one or more processors implement the method described in any implementation of the first aspect above.

[0009] Fourthly, some embodiments of this disclosure provide a computer-readable medium having a computer program stored thereon, wherein the program, when executed by a processor, implements the method described in any of the implementations of the first aspect above.

[0010] The above-described embodiments of this disclosure have the following beneficial effects: By applying the goods inbound / outbound method of some embodiments of this disclosure to a warehouse control system, equipment maintenance costs can be reduced and warehousing efficiency improved. Specifically, the reasons for increased equipment maintenance costs and reduced warehouse storage efficiency are: the high complexity of multi-level shuttle equipment; to adapt to the operating environment of multi-level shuttles, not only is it necessary to modify the warehouse design and re-plan the warehouse, requiring more cost investment, but also various difficult-to-repair fault risks (e.g., steering mechanism jamming, drive wheel power imbalance, lifting system jamming, etc.) are prone to occur during high-frequency operation, leading to blockage of the conveying channel (or conveying area), thereby increasing equipment maintenance costs and reducing warehousing efficiency. Based on this, the goods inbound / outbound method of some embodiments of this disclosure applied to a warehouse control system. First, by generating goods inbound tasks, it can be used to organize inbound / outbound tasks in advance, facilitating task planning. Then, by controlling the barcode scanning device to scan and identify the corresponding goods box number, it can be used to match the goods box number with the corresponding inbound task. Thus, it can be used to establish a correspondence between goods boxes and tasks in a large number of tasks. Next, in response to the determination that the number of layers for placing the aforementioned cargo boxes is greater than 1, the matching and warehousing task is split into elevator tasks and shuttle tasks. Here, task splitting decouples the shuttle task and elevator task, avoiding task conflicts and improving task efficiency. Then, through the shuttle task, the handling equipment is controlled to move the cargo boxes corresponding to the aforementioned cargo box numbers to the elevator waiting area. Here, because only shuttles on the same layer are called, the planning complexity is greatly reduced compared to planning tasks for all shuttles simultaneously. Thus, the handling equipment can be quickly retrieved to move the cargo boxes to the elevator waiting area. Next, based on preset priority division conditions, the elevator task is prioritized, and according to the assigned priority, the elevator task is added to the elevator loading task queue. Here, priority division allows for fine-grained division of the elevator usage order, thereby avoiding equipment conflicts for cargo box entry and exit and improving entry and exit efficiency. Subsequently, in response to the elevator loading task queue corresponding to the aforementioned elevator task, the elevator loading task is initiated, transporting the aforementioned cargo boxes from the elevator waiting area to the handling area. Finally, according to the cargo box placement layer and cargo box location number included in the matched warehousing task, the elevator and the second shuttle are used to store the aforementioned cargo boxes. Here, by calling shuttles at different cargo placement layers, the shuttle task can be decoupled. Thus, by splitting the task through multiple decouplings, the complexity of the task can be reduced. At the same time, because the shuttle does not need to perform cross-layer and cross-area operations, the complexity of warehouse design and the single operation time of the shuttle are reduced. Even in the event of equipment failure, blockage of the conveyor channel can be avoided, making it easier to maintain.This can reduce maintenance costs and improve warehousing efficiency.

[0018] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Figure 1 A flow 100 of some embodiments of a goods inbound / outbound method applied to a warehouse control system according to the present disclosure is shown. This goods inbound / outbound method applied to a warehouse control system includes the following steps: Step 101: In response to receiving a goods receiving order from the warehouse management system, generate a corresponding goods receiving task and add the goods receiving task to the receiving task queue to obtain the added task queue.

[0020] In some embodiments, the execution entity of the goods inbound / outbound method applied to the warehouse control system (e.g., the warehouse control system) can, in response to receiving a goods inbound order from the warehouse management system, generate a corresponding goods inbound task and add the goods inbound task to the inbound task queue, resulting in an added task queue. The warehouse control system and the warehouse management system communicate via a wired or wireless connection. Here, the goods inbound order can be order information requiring inbound goods. The goods inbound order may include: goods number and goods information (e.g., goods quantity). Specifically, each goods inbound order may correspond to one or more boxes for loading goods. Furthermore, a preset task generation script can be used to establish corresponding goods inbound tasks based on the goods number and goods information. The inbound task queue can be used to sort the various goods inbound tasks requiring inbound goods for orderly inbound processing. Here, the sorting can be chronological. In practice, the warehouse can have multiple entrances and exits, each corresponding to an added task queue. Each entrance and exit is equipped with a conveyor line to automatically transport the goods to be stored into the warehouse.

[0021] It should be noted that the aforementioned wireless connection methods may include, but are not limited to, 3G / 4G / 5G connections, WiFi connections, Bluetooth connections, WiMAX connections, Zigbee connections, UWB (ultra wideband) connections, and other currently known or future wireless connection methods.

[0022] It should be noted that the aforementioned warehouse control system can be either hardware or software. When the warehouse control system is hardware, it can be implemented as a distributed cluster consisting of multiple servers or terminal devices, or as a single server or terminal device. When the warehouse control system is software, it can be installed on the hardware devices listed above. It can be implemented as, for example, multiple software programs or software modules used to provide distributed services, or as a single software program or software module. No specific limitations are made here.

[0023] Step 102: Control the scanning device to scan and identify the goods box delivered to the scanning location to obtain the corresponding goods box number.

[0024] In some embodiments, the aforementioned executing entity can control a barcode scanning device to scan and identify the barcodes of the boxes delivered to the scanning location, thereby obtaining the corresponding box number. Each conveyor line is equipped with a barcode scanning device for scanning and identifying the labels (physical or electronic) on the boxes to obtain the corresponding box number. Here, the box number corresponds to the item number in the goods receiving task.

[0025] Optionally, if the cargo box is not bound to the goods and is placed directly on the conveyor line when the goods enter the warehouse, a barcode scanner can be used to scan the goods inside the cargo box to determine the item number. This allows the correspondence between the goods and the cargo box to be established.

[0026] In practice, the initial WCS (Warehouse Control System) had simple control functions, poor system stability, and many problems (such as insufficient elevator utilization and unreasonable priority allocation), which seriously affected the efficiency of inbound and outbound operations. Therefore, after in-depth research and analysis, we improved the efficiency of inbound and outbound operations by optimizing task strategies and storage strategies, and improved the system stability by perfecting the information transmission and reception mechanism between systems, as detailed below.

[0027] Step 103, perform the following warehousing steps for the cargo box number: Step 1031: Match the cargo box number with the cargo inbound tasks in the added task queue to obtain the matched inbound tasks.

[0028] In some embodiments, the executing entity can perform task matching between the cargo box number and the cargo receiving tasks in the added task queue to obtain matched receiving tasks. The matched receiving task may include the cargo box placement layer number and the cargo box storage location number. Here, the cargo box placement layer number can be the layer where the cargo box is stored. The cargo box storage location number can be the storage location number at the layer to be stored. Furthermore, task matching can involve selecting receiving tasks from the added task queue that correspond to the cargo box number. Thus, the correspondence between the cargo code, the cargo box number, and the receiving tasks (i.e., the cargo box placement layer number and the cargo box storage location number) can be determined.

[0029] Step 1032: In response to determining that the number of layers of cargo boxes is greater than 1, the matched inbound task is split into a hoist task and a shuttle task.

[0030] In some embodiments, the executing entity may, in response to determining that the number of layers for placing the cargo boxes is greater than 1, split the matched warehousing task into a hoist task and a shuttle task. A cargo box placement layer greater than 1 indicates that a hoist is required for cargo storage. In practice, goods may be entered into the warehouse from layer 0 (i.e., the ground floor) and stored on one of layers 1 to n (e.g., 4 layers). Here, the task tag for the matched warehousing task can be split into a hoist task tag and a shuttle task tag. Then, the hoist task tag and the information in the matched warehousing task can be used to determine the hoist task, and the shuttle task tag and the information in the matched warehousing task can be used to determine the shuttle task. The hoist task can be a task for using a hoist to lift and lower cargo boxes. The shuttle task can be a task for calling a shuttle to move cargo boxes. The hoist can be a device for lifting and lowering goods.

[0031] Optionally, if the number of layers for placing the cargo boxes is equal to 1, then a hoist is not required. Therefore, there is no need to split the task; the matched inbound task can be treated as a shuttle task.

[0032] Step 1033: Through the shuttle mission, control the handling equipment to move the cargo box corresponding to the cargo box number to the elevator waiting area.

[0033] In some embodiments, the aforementioned executing entity can control the handling equipment to move the cargo box corresponding to the aforementioned cargo box number to the elevator waiting area through the aforementioned shuttle task. The aforementioned handling equipment can be a first shuttle or a (roller-type) conveyor line. The first shuttle is a shuttle located on the same floor as the aforementioned cargo box and is in an idle state.

[0034] In some optional implementations of certain embodiments, the aforementioned handling equipment may include at least one shuttle. The executing entity, through the shuttle's task, controls the handling equipment to move the cargo box corresponding to the aforementioned cargo box number to the elevator waiting area, including: Step S1: Identify the idle shuttles to obtain an idle shuttle group. When calling a shuttle, its availability can be determined by checking its status. For example, the shuttle's status flag can be checked: a status flag "1" indicates it is occupied, and a status flag "0" indicates it is idle.

[0035] Step S2 involves selecting the idle shuttle closest to the cargo box from the idle shuttle group as the first shuttle, and controlling the first shuttle to move the cargo box corresponding to the cargo box number to the elevator waiting area. This process involves obtaining the position of the idle shuttle, then using the position of the scanning device as the location of the cargo box to determine the distance between the idle shuttle and the cargo box. Therefore, the closest idle shuttle can be selected as the first shuttle.

[0036] Step S3: In response to determining that the idle shuttle group is empty (i.e., all shuttles are in working condition), based on the location information of each shuttle, the shuttles are divided into task partitions according to multiple pre-divided inventory intervals, resulting in a set of partitioned shuttle identifier groups. Each partitioned shuttle identifier group corresponds to one task partition. The multiple inventory intervals are pre-divided intervals for the inventory area. Then, according to the location of the shuttle, the shuttle identifiers can be assigned to the corresponding inventory intervals to obtain the set of partitioned shuttle identifier groups.

[0037] In practice, to avoid excessive task prioritization and the resulting competition for shuttles due to tasks with the same priority, inventory zones are divided to process shuttles in batches from a spatial perspective. This not only allows for faster selection of the required shuttles but also prevents shuttles from traversing excessive distances to complete tasks. Furthermore, because idle shuttles are prioritized for task assignment, and shuttle selection is only made based on task zones when all shuttles are occupied, there is no issue of excessive shuttle accumulation in any area. Therefore, except in cases where no shuttle is available within the required inventory zone, there is no need to set rules such as shuttle quantity limits for inventory zones. This reduces restrictions on shuttles and improves warehousing efficiency. Additionally, inventory zones can be divided equally among different areas, such as dividing a rectangular inventory area into four equal zones. Alternatively, they can be divided according to warehouse entrances and exits, with each entrance and exit area forming a separate inventory zone.

[0038] Optionally, the handling equipment (on the ground floor) may also include a (roller-type) conveyor line. Therefore, during warehousing, the conveyor line can transport boxes with bound product information and storage location information to the barcode scanning device. The barcode scanning device transmits the scanned box number to the WCS. The WCS matches the generated warehousing task to determine the layer and storage location number where the box is placed. At the same time, it communicates with the elevator and the shuttle (on other layers besides the ground floor) to read the working status of the elevator and the shuttle. When the elevator is idle, it sends a task to the elevator to receive boxes from the first-floor conveyor line and transport them to the designated layer. After receiving the corresponding task, the elevator starts working and transports the boxes to the buffer position on the designated layer. After the WCS receives the boxes and the boxes arrive at the buffer position, it sends a task to the shuttle on the corresponding layer to receive boxes from the buffer position and transport them to the designated storage location. After the WCS determines that the shuttle task has been completed, it feeds back the warehousing completion status to the WMS (Warehouse Management System). When the goods are being shipped out, the WCS sends a command to the shuttle to retrieve a box from the designated storage location and transport it to the designated buffer position on the first floor. After the shuttle has completed its task, the WCS sends a command to the elevator to retrieve a box from the designated buffer position on the first floor and transport it to the first-floor conveyor line. After the elevator has completed its task, the WCS communicates with the conveyor line, which then transports the box to the outbound exit. At the same time, the WCS sends the outbound completion status back to the WMS.

[0039] For the shuttle's execution process: The shuttle can work by receiving instructions from the WCS. After the WCS determines that the shuttle is in an idle state, it sends an instruction to the shuttle to pick up goods at the designated pickup location. After the shuttle runs to the designated pickup location and completes the pickup, it sends a status feedback to the WCS. After receiving the shuttle's pickup completion, the WCS sends an instruction to the shuttle to go to the designated drop-off location to drop off the goods. After the shuttle drops off the goods, it updates its working status and sends a drop-off completion status feedback to the WCS.

[0040] The elevator's operation process is as follows: The elevator primarily operates by receiving instructions from the WCS (Warehouse Control System). During inbound operations, after receiving the task from the WCS, the elevator first moves from its current level to the first-level conveyor line. Upon reaching the first-level conveyor line, it sends feedback on whether inbound access is permitted to the WCS. Simultaneously, it rotates the (conveyor line's) roller shaft, transporting the box to the elevator. After reaching the elevator, it moves to the designated loading level and places the box in the elevator's buffer position (transfer area), sending a status update back to the WCS. During outbound operations, the elevator first moves to the designated picking level to retrieve the goods. After retrieval, it moves to the first-level conveyor line. Upon reaching the first-level conveyor line, it communicates with the WCS to request outbound access. Upon receiving permission from the WCS, it rotates the roller to transport the box to the first-level conveyor line for outbound processing.

[0041] Step S4: Determine the task partition where the above-mentioned cargo box is located as the current task partition, and determine the shuttle identification group after the partition corresponding to the current task partition as the current shuttle identification group.

[0042] Step S5: Based on the task information corresponding to each current shuttle identifier in the current shuttle identifier group, filter the current shuttle identifiers to obtain the target shuttle identifier. This filtering can involve selecting the current shuttle identifier that completes its task fastest from the current shuttle identifier group as the target shuttle identifier. Here, the task information for each shuttle includes an estimated task duration. After assigning a new task to the target shuttle, the estimated task duration is accumulated, thus changing its estimated task duration. This avoids repeatedly assigning tasks to the target shuttle.

[0043] Step S6: The shuttle corresponding to the target shuttle identifier is identified as the first shuttle. In response to the determination that the first shuttle has completed its task, the first shuttle is invoked to move the cargo box corresponding to the cargo box number to the elevator waiting area. The completion of the first shuttle's task signifies the end of its previous task, allowing it to execute the current task of moving the cargo box corresponding to the cargo box number to the elevator waiting area.

[0044] In practice, the cargo boxes corresponding to the above cargo box numbers can be moved to the elevator waiting area by placing the cargo boxes directly in the elevator waiting area, or by placing the cargo boxes on the conveyor line so that the conveyor line can automatically transport the cargo boxes to the elevator waiting area.

[0045] Step 1034: According to the preset priority division conditions, the hoist tasks are divided into task priorities, and the hoist tasks are added to the hoist mounting task queue according to the divided task priorities.

[0046] In some embodiments, the execution entity may divide the hoist tasks into task priorities according to preset priority division conditions, and add the hoist tasks to the hoist mounting task queue according to the divided task priorities.

[0047] In some optional implementations of certain embodiments, to improve the efficiency of the elevator and avoid congestion of cargo flow within the elevator and increased computational complexity due to excessive handling zones, four handling zones are provided within the elevator. Each handling zone corresponds to two cargo inlets / outlets, and each cargo placement layer has a waiting task queue corresponding to each cargo inlet / outlet. Furthermore, the volume of the cargo box is much larger than the gap between the cargo box inlet / outlet, thereby preventing the cargo box from getting stuck.

[0048] As an example, see such Figure 2The diagram shows a hoist. The hoist's worktable is divided into four transport zones: transport zone 201, transport zone 202, transport zone 203, and transport zone 204. Each transport zone corresponds to two cargo inlets / outlets. For example, transport zone 201 is labeled as cargo inlet / outlet a and cargo inlet / outlet b. Transport zone 202 is labeled as cargo inlet / outlet c and cargo inlet / outlet d. Transport zone 203 is labeled as cargo inlet / outlet e and cargo inlet / outlet f. Transport zone 204 is labeled as cargo inlet / outlet g and cargo inlet / outlet h. Each cargo inlet / outlet can correspond to a hoist waiting area for cargo box exchange. The arrows in the diagram indicate the direction of cargo box movement. In practice, the hoist waiting area can be a location on the conveyor line adjacent to the hoist, such as... Figure 2 The eight dashed boxes in the diagram indicate the locations of the cargo boxes. Here, when the cargo box is in this location area, the corresponding roller on the conveyor line can be paused, so that the cargo box stops in the area adjacent to the elevator inlet (i.e., the location area). This area is called the elevator waiting area.

[0049] The aforementioned execution entity, based on preset priority criteria, prioritizes the hoist tasks and adds them to the hoist loading task queue according to the prioritized tasks, including: Step S1: Based on the matched warehousing tasks described above, add the elevator tasks to the corresponding waiting task queue. The waiting task queue can be a queue of tasks awaiting loading. Here, since the number of goods entering and leaving the elevator exceeds the number of handling areas, each goods handling operation cannot satisfy all goods entering and leaving. Therefore, a corresponding waiting task queue is set up for each goods entering and leaving. Here, the elevator task can be added to the tail of the corresponding waiting task queue based on the identifier of the elevator waiting area corresponding to the matched warehousing task.

[0050] Step S2: In response to determining that the aforementioned elevator task is at the head of the waiting task queue, the head task information of each waiting task queue on the same cargo placement layer is obtained to obtain the head task information set. Wherein, the aforementioned elevator task being at the head of the waiting task queue indicates that all other tasks previously in the waiting task queue have already been loaded or executed. Therefore, the head task information in each waiting task queue can be selected again as the head task information set.

[0051] Step S3: According to the preset priority division conditions, the priority of each first task information in the first task information set is divided to obtain the task priority queue. The preset priority division conditions include: outbound priority division conditions, which are used to increase the task priority of outbound tasks.

[0052] In practice, considering the large number of goods entering and leaving the hoist, to avoid task congestion (e.g., tasks for a certain goods entry or exit being stalled for an extended period) and ensure smooth task execution, the first task information of each waiting task queue is selected each time to obtain a first task information set. This ensures that each goods entry / exit has a cargo box assigned a task for execution. Specifically, to further improve cargo transportation efficiency, a preset priority division condition is introduced to prioritize the first task information in the aforementioned first task information set. Here, because priority division is performed only on the first task information of goods entry / exit (i.e., a maximum of 8 first task information items), compared to prioritizing all order tasks simultaneously, the data volume is significantly reduced, thereby improving priority division efficiency and reducing priority division conflicts. This, in turn, improves task execution efficiency.

[0053] As an example, the above priority division can be based on the entry time of each first and second task's information, or it can be based on the priority level pre-marked in each first and second task's information. Thus, a task priority queue can be obtained.

[0054] Optionally, when prioritizing, if there are both outbound and inbound cargo boxes, prioritize the cargo boxes that are already in place at the current level. If there are both outbound and unassigned cargo boxes (waiting at the inbound position on the conveyor line), prioritize outbound.

[0055] Step S4: Using the task priority corresponding to the hoist task in the task priority queue, add the hoist task to the hoist mounting task queue. The number of tasks in the hoist mounting task queue is fixed (e.g., 4). Each time the hoist completes one or more hoist mounting tasks, a corresponding number of hoist tasks can be selected according to task priority and mounted to the hoist mounting task queue for execution when the hoist arrives again.

[0056] In practice, the hoist's task queue can be further divided into an upward task queue and a downward task queue, so that the corresponding task can be selected and executed when the hoist is moving upward or downward. Similarly, the waiting task queue can also be divided into an upward waiting task queue and a downward waiting task queue.

[0057] As an example, there are three layers of goods placement: layer F1, layer F2, and layer F3. Each layer has eight goods inlets and outlets, and each inlet and outlet can have a corresponding upward waiting task queue (Lup) and downward waiting task queue (Ldown). Here, the first layer only has an upward waiting task queue, and the top layer only has a downward waiting task queue. For example, the upward waiting task queue (Lup) for goods inlet / outlet a in layer F2 is: [an1, an2, an3, an4, an5, an6, an7]. The upward waiting task queue (Lup) for goods inlet / outlet b in layer F2 is: [bn1, bn2, bn3, bn4, bn5]. The upward waiting task queue (Lup) for goods inlet / outlet c in layer F2 is: [cn1, cn2, cn3]. The upward waiting task queue (Lup) for goods inlet / outlet d in layer F2 is: [dn1, dn2, dn3, dn4, dn5]. The uplink waiting task queue Lup corresponding to the import / export e of goods in the second layer F2 is: [en1, en2]. The uplink waiting task queue Lup corresponding to the import / export f of goods in the second layer F2 is: [fn1, fn2]. The uplink waiting task queue Lup corresponding to the import / export g of goods in the second layer F2 is [empty]. The uplink waiting task queue Lup corresponding to the import / export h of goods in the second layer F2 is: [empty].

[0058] The downlink waiting task queue Ldown for goods import / export a in layer F2 is: [am1, am2, am3, am4]. The uplink waiting task queue Ldown for goods import / export b in layer F2 is: [bm1, bm2, bm3, bm4, bm5]. The uplink waiting task queue Ldowm for goods import / export c in layer F2 is: [cm1, cm2, cm3]. The uplink waiting task queue Ldown for goods import / export d in layer F2 is: [dm1, dm2, dm3, dm4, dm5]. The uplink waiting task queue Ldown for goods import / export e in layer F2 is: [empty]. The uplink waiting task queue Ldown for goods import / export f in layer F2 is: [empty]. The uplink waiting task queue Ldown for goods import / export g in layer F2 is: [gm1, gm2, gm3]. The uplink waiting task queue Ldown for goods import / export h in layer F2 is: [fm1, fm2].

[0059] After selecting tasks by priority, the uplink load queue Zup corresponding to the second layer F2 can be [an1, bn1, cn1, and dn1], and the downlink load queue Zdown can be [am1, bm1, gm1, fm1]. Therefore, when the hoist ascends to the second layer F2, a hoist load task can be selected from the uplink load queue. When the hoist descends to the second layer F2, a hoist load task can be selected from the downlink load queue.

[0060] Step 1035: In response to the start of the hoist loading task corresponding to the hoist task in the hoist loading task queue, the cargo box is transported from the hoist waiting area to the handling area.

[0061] In some embodiments, the aforementioned execution entity may, in response to the initiation of a hoist loading task corresponding to the aforementioned hoist task in the hoist loading task queue, transport the aforementioned cargo box from the hoist waiting area to the (hoist's) handling area.

[0062] In some alternative implementations of some embodiments, the four transport zones within the elevator are provided with rotating pallets, each with a roller assembly. The roller assembly is used to adjust the orientation of the rotating pallet and to transport the cargo box in a target direction. When the target direction is towards an adjacent transport zone, the transport zone where the cargo box is located is adjusted by rotating the roller assembly.

[0063] As an example, see again Figure 2 The diagram shows a hoist. A rotating pallet 2011, rotating pallet 2021, rotating pallet 2031, and rotating pallet 2041 are provided in transport areas 201, 202, 203, and 204 respectively. The orientation of the rotating pallets can be adjusted by controlling them, thereby orienting the roller assemblies on the rotating pallets towards the direction of cargo transport, thus controlling the roller assemblies to move the cargo boxes. For example, if a cargo box needs to be transferred from the cargo inlet / outlet a of transport area 201 to the conveyor line, the rotating pallet 2011 can be oriented towards cargo inlet / outlet a, and then the roller assemblies can be rotated to move the cargo box to the conveyor line. Similarly, if a cargo box needs to be transferred from transport area 201 to transport area 202, the drive direction of the rotating pallet 2011 can first be controlled towards transport area 202. Then, the rotating pallet 302 is oriented in the same direction, so that the drive directions of the roller assemblies on the rotating pallets 2021 and 2011 are the same. Finally, by simultaneously activating the roller assemblies on rotating pallets 2011 and 2021, the cargo box can be transferred from the handling area 201 to the handling area 202.

[0064] As another example, when the eight cargo inlets and outlets of the elevator are not explicitly defined as performing single-task operations (e.g., only performing inbound or only performing outbound tasks), considering the possibility of cargo congestion (e.g., all cargo inlets and outlets are for goods requiring inbound, but all cargo boxes on the elevator are for goods requiring outbound, causing blockages), not all can be set as inlets or outlets. Therefore, the settings for cargo inlets and outlets can be pre-adjusted based on the ratio of outbound to inbound orders. For example, if the ratio of outbound to inbound orders is 1:1, then four cargo inlets and outlets can be used as cargo inlets, and four as cargo outlets, thus avoiding cargo congestion.

[0065] The aforementioned executing entity, in response to the initiation of the hoist loading task corresponding to the aforementioned hoist task in the hoist loading task queue, transports the aforementioned cargo container from the hoist waiting area to the handling area, including: Step S1: In response to detecting that the elevator's moving target is the current cargo placement layer, check whether there are any vacant transport areas on the elevator. Each transport area of ​​the elevator can be equipped with an occupancy indicator to indicate whether the transport area is occupied. Therefore, by detecting the occupancy indicator, it can be determined whether there are any vacant transport areas on the elevator. In practice, after the elevator reaches each cargo placement layer, it can prioritize transporting the cargo boxes that need to be moved out of the transport area, and then calculate the remaining vacant transport areas, thereby improving the utilization rate of the elevator. Therefore, the transport area containing the cargo boxes that the elevator needs to transport from the current cargo placement layer can also be considered a vacant transport area.

[0066] Here, in order to avoid the elevator staying on each floor for too long, it is possible to detect whether there is an empty transport area on the elevator before it reaches the current cargo placement floor (i.e., before it reaches the current cargo placement floor). It is also possible to count the empty transport area before the elevator reaches the current cargo placement floor from the previous cargo placement floor.

[0067] Step S2: In response to the existence of idle transport areas, and the number of idle transport areas being greater than 1, a target number of hoist loading tasks are selected from the hoist loading task queue as execution task groups, and the hoist loading task is initiated. Since at least one empty space needs to be left inside the hoist for cargo transfer between transport areas, the number of cargo boxes stored in the hoist at the same time is less than or equal to 3. Here, if the number of idle transport areas is greater than 1, then at least two idle transport areas are determined, and the target number = number of idle transport areas – 1. Therefore, after selecting the number of tasks to be executed, the corresponding hoist loading tasks can be sequentially selected from the hoist loading task queue as execution task groups, and the hoist loading task is initiated. Here, after selecting the corresponding hoist loading tasks, firstly, it can be determined whether the transport area on the hoist corresponding to the above hoist loading task is empty. If it is not empty, cargo transfer is performed, and then the cargo boxes corresponding to the hoist loading task are moved to the transport area in the above manner.

[0068] In particular, if it is determined in advance that the various tasks within the elevator do not need to exchange positions with each other, then four cargo boxes can be stored in each transport area at the same time.

[0069] Step S3: Upon detecting that the elevator has reached the current cargo placement layer, the corresponding conveyor line for the execution task group is activated, and the corresponding cargo box is transported to the corresponding handling area. Each cargo box corresponds to one handling area. Simultaneously with activating the conveyor line for the execution task group, the rotating pallet corresponding to the elevator can be oriented towards the cargo transport direction to synchronously activate the roller assembly, assisting in transporting the cargo box to the handling area.

[0070] Step 1036: According to the number of layers and storage location of the cargo boxes included in the matched warehousing task, use the elevator and the second shuttle to store the cargo boxes.

[0071] In some embodiments, the aforementioned executing entity may use a hoist and a second shuttle to store the goods according to the number of layers and storage location of the goods boxes included in the matched storage task.

[0072] In some optional implementations of certain embodiments, the executing entity, according to the number of cargo box placement layers and cargo box location numbers included in the matched warehousing task, utilizes a hoist and a second shuttle to perform cargo warehousing for the aforementioned cargo boxes, including: Step S1: Based on the matched warehousing task described above, path planning is performed on each cargo box within the elevator to obtain a set of cargo box warehousing paths. Each cargo box warehousing path corresponds to one cargo box, and each path includes: a handling area identifier, a cargo inlet / outlet identifier, the cargo box placement layer number, and a conveyor line identifier. Here, a preset path planning algorithm can be used to plan the paths for each cargo box within the elevator. During path planning, the handling area and cargo inlet / outlet are considered, with the cargo box placement layer number and cargo box location number as the planning targets, resulting in cargo box warehousing paths with conveyor line identifiers. Specifically, there are multiple conveyor lines from the current location of the cargo box to its location number; path planning can select one of these conveyor lines as the path.

[0073] As an example, path planning algorithms may include, but are not limited to, at least one of the following: Dijkstra's algorithm, Algorithms, fast exploratory random trees, artificial potential field methods, etc.

[0074] Step S2: Based on the aforementioned cargo box entry path set, control the rotating pallet and roller assembly within the elevator to adjust the handling area corresponding to each cargo box. Specifically, by controlling the handling area (rotating pallet and roller assembly) corresponding to each cargo box, the cargo boxes can be pre-positioned at their respective cargo inlets / outlets according to the cargo box entry path, thus saving time and improving cargo transportation efficiency.

[0075] Step S3: In response to the elevator reaching the cargo placement layer, the roller assembly of the corresponding handling area is controlled to transport the cargo box to the corresponding conveyor line according to the above cargo box entry path set.

[0076] Step S4 involves determining the second shuttle and controlling it to store the cargo boxes. The second shuttle is located on the layer where the cargo boxes are placed. The method for determining the second shuttle and its corresponding technical effects can be found in step 1033 above, and will not be elaborated further. Secondly, after reaching the cargo placement layer, the elevator can simultaneously control the transport of cargo boxes in each handling area. That is, the rotating pallets and roller assemblies in each handling area can operate synchronously. The elevator has an upward cargo queue and a downward cargo queue. Based on the upward and downward cargo queues, the elevator's upward and downward directions are adjusted. Specifically, it can detect whether the upward and downward cargo queues are empty. If the upward queue is empty and the downward queue is full, and the elevator is moving upward, the elevator's direction can be adjusted to move downward directly. Furthermore, the elevator stays for the same amount of time on different cargo placement layers. Therefore, by changing the position of the cargo boxes during the elevator's operation, cargo boxes can be directly transported during stops, thus avoiding excessive dwell time on certain placement layers. This, in turn, improves the efficiency of goods circulation.

[0077] Furthermore, if a particular hoist is overloaded, the task can be transferred to another hoist. In practice, this implementation method not only greatly improves cargo storage efficiency, but also further enhances storage efficiency by adjusting the hoist's handling logic and structural design, without requiring the replacement of shuttle cars, thus avoiding cargo jams.

[0078] Optionally, the aforementioned implementing entity may also perform the following steps: Step S1: In response to receiving a goods outbound order from the warehouse management system, generate a goods outbound task based on the goods outbound order.

[0079] Step S2: Based on the aforementioned goods outbound task, control the second shuttle and the elevator to outbound the goods boxes. Specifically, the implementation method and corresponding technical effects of goods outbound can be found in the above embodiments, and will not be elaborated further.

[0080] Optionally, the aforementioned implementing entity may also perform the following steps: Step S1 involves performing frequency analysis on historical order sequences in the database to generate a set of product frequency description information. This includes extracting order information and total outbound volume from the historical order sequences. Order information can include the absolute frequency of products. The relative frequency of each product is then determined, where relative frequency = (absolute frequency of a product) ÷ (total number of orders in the same period / total outbound volume) × 100%. Thus, the relative frequency and product tags can be used as product frequency description information. The total number of orders in the same period can be the total number of orders within the same time frame.

[0081] In addition, the frequency of goods can be counted at fixed periods (such as daily, weekly, or monthly) to identify high-frequency patterns within a specific period and add them to the goods frequency description information.

[0082] Step S2: According to preset cargo adjustment rules, the cargo positions corresponding to the aforementioned cargo frequency description information set are adjusted using shuttle cars and elevators. The cargo adjustment rules may be designed to place frequently used cargo closer to the warehouse exit.

[0083] As an example, Category A goods: highest frequency (e.g., accounting for 70%-80% of total frequency), but may only account for 10%-20% of quantity, should be placed in the most convenient location (e.g., near entrances / exits, at the front of picking aisles). Category B goods: medium frequency (e.g., accounting for 15%-25% of total frequency), and approximately 30%-40% of quantity, should be placed in the less convenient location. Category C goods: lowest frequency (e.g., accounting for 5%-10% of total frequency), and accounting for over 50% of quantity, can be placed deep within the warehouse or on high-level shelves. Therefore, the positions of goods can be adjusted sequentially when shuttles and elevators are idle, thus saving transportation time and improving warehousing efficiency.

[0084] Additionally, if a certain product is packaged in multiple cargo boxes, the cargo box closest to the shuttle car will be sorted first (the distance is calculated based on the weighted sum of actual distances to obtain the overall task time). If two cargo boxes are equidistant from the shuttle car, the cargo box closer to the elevator will be sorted first. If the quantity of the product to be sorted is less than the inventory of one of the cargo boxes, that cargo box will be sorted first. If multiple cargo boxes meet the requirements simultaneously, or if none of the cargo boxes meet the requirements, the cargo box closest to the shuttle car will be sorted first.

[0085] In practice, the above implementation methods optimized the timing and quantity of tasks issued by the WCS, the timing and order of tasks executed by the elevator, matched the elevator buffer space with the number of cargo boxes, and closely coordinated the tasks of the elevator and the shuttle. After applying these strategies, the efficiency of cargo boxes moving up and down shelves via the elevator was improved, the time for the elevator to perform inbound tasks was reduced by about half, and the situation of the elevator lifting and lowering without load when there were simultaneous inbound and outbound operations was eliminated. Secondly, the outbound order of goods was optimized to improve outbound efficiency. The simple first-in-first-out (FIFO) sorting strategy has the problem of many shuttle runs and long overall running time. On the basis of the default sorting, two more prioritized factors were added: first, the comparison between the inventory of goods in the cargo box and the total outbound quantity of that goods; and second, the distance between the shuttle and the location of the task cargo box and the elevator position, thus determining a more efficient outbound sorting strategy. Thirdly, the placement of goods in the storage location was optimized to reduce the task distance of the shuttle. The current placement of goods affects the shuttle's travel distance during subsequent outbound shipments. By taking a holistic approach, the repetition rate of goods from historical orders is incorporated into the goods placement process, shortening the task distance for frequently shipped items. Optimizing the outbound sequence and goods placement reduces the overall expected outbound time. The more numerous the items in a single outbound shipment and the more stable the historical order history, the more significant the improvement.

[0086] The above-described embodiments of this disclosure have the following beneficial effects: By applying the goods inbound / outbound method of some embodiments of this disclosure to a warehouse control system, equipment maintenance costs can be reduced and warehousing efficiency improved. Specifically, the reasons for increased equipment maintenance costs and reduced warehouse storage efficiency are: the high complexity of multi-level shuttle equipment; to adapt to the operating environment of multi-level shuttles, not only is it necessary to modify the warehouse design and re-plan the warehouse, requiring more cost investment, but also various difficult-to-repair fault risks (e.g., steering mechanism jamming, drive wheel power imbalance, lifting system jamming, etc.) are prone to occur during high-frequency operation, leading to blockage of the conveying channel (or conveying area), thereby increasing equipment maintenance costs and reducing warehousing efficiency. Based on this, the goods inbound / outbound method of some embodiments of this disclosure applied to a warehouse control system. First, by generating goods inbound tasks, it can be used to organize inbound / outbound tasks in advance, facilitating task planning. Then, by controlling the barcode scanning device to scan and identify the corresponding goods box number, it can be used to match the goods box number with the corresponding inbound task. Thus, it can be used to establish a correspondence between goods boxes and tasks in a large number of tasks. Next, in response to the determination that the number of layers for placing the aforementioned cargo boxes is greater than 1, the matching and warehousing task is split into elevator tasks and shuttle tasks. Here, task splitting decouples the shuttle task and elevator task, avoiding task conflicts and improving task efficiency. Then, through the shuttle task, the handling equipment is controlled to move the cargo box corresponding to the aforementioned cargo box number to the elevator waiting area. Here, because only shuttles on the same layer are called, the planning complexity is greatly reduced compared to planning tasks for all shuttles simultaneously. Thus, the handling equipment can be quickly called to move the cargo box corresponding to the cargo box number to the elevator waiting area. Next, according to preset priority division conditions, the elevator task is prioritized, and based on the assigned priority, the elevator task is added to the elevator loading task queue. Here, priority division allows for fine-grained division of the elevator usage order, thereby avoiding equipment conflicts for cargo box entry and exit and improving entry and exit efficiency. Subsequently, in response to the elevator loading task queue corresponding to the aforementioned elevator task, the elevator loading task is initiated, transporting the aforementioned cargo boxes from the elevator waiting area to the handling area. Finally, according to the cargo box placement layer and cargo box location number included in the matched warehousing task, the elevator and the second shuttle are used to store the aforementioned cargo boxes. Here, by calling shuttles at different cargo placement layers, the shuttle task can be decoupled. Thus, by splitting the task through multiple decouplings, the complexity of the task can be reduced. At the same time, because the shuttle does not need to perform cross-layer and cross-area operations, the complexity of warehouse design and the single operation time of the shuttle are reduced. Even in the event of equipment failure, blockage of the conveyor channel can be avoided, making it easier to maintain.This can reduce maintenance costs and improve warehousing efficiency.
