Description

Technical Field

[0001] This invention relates to the field of warehousing and logistics technology, and in particular to a method, apparatus, equipment and storage medium for the outbound shipment of goods. Background Technology

[0002] With the continuous improvement of people's consumption power, the number of goods leaving the warehouse every day is enormous. In order to improve the outbound efficiency of the warehouse system, many warehouse systems have begun to adopt RFID (Radio Frequency Identification) data collection equipment. RFID data collection equipment automatically identifies the RFID tag information on the goods through radio frequency identification signals, which is quick and convenient to operate.

[0003] In a warehousing system, outbound goods typically go through multiple stages, including picking, verification, and sorting. During the picking and verification stages, RFID readers need to collect the RFID tag information of the outbound goods for verification.

[0004] In the process of realizing this invention, at least the following technical problems were found in the prior art:

[0005] Since RFID tags uniquely identify each item, collecting tag information from multiple layers and times when dealing with bulk outbound orders consumes a lot of manpower and time, increases labor costs, and reduces the outbound efficiency of the warehousing system. Summary of the Invention

[0006] This invention provides a method, apparatus, equipment, and storage medium for outbound goods, in order to solve the problem of high manpower consumption in collecting multi-layer and multiple tag information, reduce labor costs, and improve the outbound efficiency of the warehousing system.

[0007] According to an embodiment of the present invention, a method for issuing goods from a warehouse is provided, the method comprising:

[0008] In response to the detection of an item order, the order type of the item order is obtained;

[0009] When the order type is a bulk order, a picking operation is performed based on the minimum inventory unit and the quantity of items in the item order to obtain the picked items;

[0010] Obtain the RFID tag information corresponding to each of the picked items collected by the RFID collection device;

[0011] Based on the RFID tag information, a composite verification operation is performed to obtain the composite verification result corresponding to the item order; wherein, the composite verification operation is used to characterize the verification operation that integrates picking verification and review verification;

[0012] If the composite verification result is successful, an outbound operation is performed on each of the picked items.

[0013] According to another embodiment of the present invention, an item dispatching device is provided, the device comprising:

[0014] The order type acquisition module is used to acquire the order type of an item order in response to the detection of an item order;

[0015] The picking operation execution module is used to perform picking operations to obtain picked items based on the minimum inventory unit and item quantity in the item order when the order type is a batch order.

[0016] The RFID tag information acquisition module is used to acquire the RFID tag information corresponding to each of the picked items collected by the RFID acquisition device.

[0017] The composite verification result determination module is used to perform a composite verification operation based on the RFID tag information to obtain the composite verification result corresponding to the item order; wherein, the composite verification operation is used to characterize the verification operation that integrates picking verification and review verification;

[0018] The outbound operation execution module is used to perform outbound operations on each of the picked items when the composite verification result is successful.

[0019] According to another embodiment of the present invention, an electronic device is provided, the electronic device comprising:

[0020] At least one processor; and

[0021] A memory communicatively connected to the at least one processor; wherein,

[0022] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the item release method according to any embodiment of the present invention.

[0023] According to another embodiment of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions, the computer instructions being configured to cause a processor to execute and implement the item release method according to any embodiment of the present invention.

[0024] The technical solution of this invention, for item orders of the batch order type, performs a picking operation based on the minimum inventory unit and item quantity in the item order to obtain the picked items. In the verification stage, the RFID tag information of the picked items is collected once. Based on the RFID tag information, a composite verification operation is performed to obtain the composite verification result corresponding to the item order. If the composite verification result is successful, the picked items are processed for outbound. This solves the problem of the large amount of manpower required for collecting tag information at multiple levels and times, reduces the number of times RFID tag information is collected in the outbound process, reduces labor costs, and improves the outbound efficiency of the warehousing system.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0035] Figure 1 This is a flowchart illustrating a method for issuing goods from a warehouse, as provided in one embodiment of the present invention. This embodiment is applicable to issuing goods from orders in a warehousing system, particularly for bulk orders. The method can be executed by a goods issuing device, which can be implemented in hardware and / or software and can be configured in a terminal device. Figure 1 As shown, the method includes:

[0036] S110. In response to the detection of an item order, obtain the order type of the item order.

[0037] Specifically, the order type is defined based on the quantity of items in the order. In this embodiment, the order type is either a bulk order or a retail order. For example, bulk orders are typically ToB (To Business) orders, while retail orders are typically ToC (To Consumer) orders.

[0038] In one specific embodiment, obtaining the order type of an item order includes: obtaining the quantity of items in the item order; determining whether the quantity of items is greater than a preset quantity threshold; if so, setting the order type of the item order to a batch order; if not, setting the order type of the item order to a retail order.

[0039] For example, the preset quantity threshold can be 20 or 30 pieces. There is no limitation on the preset quantity threshold here, and users can customize the setting according to their actual needs.

[0040] In another specific embodiment, the method further includes: in response to detecting a wavelet set order, obtaining the item quantities corresponding to at least two item orders in the wavelet set order, and taking the item orders with item quantities greater than a preset quantity threshold as target item orders; obtaining the set order quantity corresponding to the wavelet set order and the target order quantity corresponding to each target item order; and if the ratio between the target order quantity and the set order quantity is greater than a preset ratio threshold, setting the order type corresponding to each item order in the wavelet set order to batch order.

[0041] Specifically, a wavelet order contains at least two item orders corresponding to a picking task. When the warehouse system detects multiple item orders, it typically combines a certain number of item orders into a wavelet order. Based on the source warehouse locations corresponding to each item order in the wavelet order, it plans picking routes, and picking personnel or picking equipment execute picking tasks based on these routes.

[0042] For example, the preset quantity threshold can be 20 or 30 pieces, and the preset ratio threshold can be 80% or 90%. There are no restrictions on the preset quantity threshold and the preset ratio threshold. Users can customize the settings according to their actual needs.

[0043] For example, suppose a batch collection order contains item order 1, item order 2, and item order 3, with item order 1, item order 2, and item order 3 corresponding to item quantities of 50, 2, and 30 items respectively. The preset quantity threshold is 20 items, and the preset ratio threshold is 50%. Then, item order 1 and item order 3 are both target item orders, the total number of orders in the collection is 3, the number of target orders is 2, and the ratio between the number of target orders and the total number of orders in the collection is greater than 50%. Accordingly, item order 1, item order 2, and item order 3 are all set as batch orders.

[0044] Based on the above embodiments, specifically, the method further includes: when the ratio between the target order quantity and the aggregated order quantity is less than or equal to a preset ratio threshold, and the target order quantity is less than the target quantity threshold, setting the order type corresponding to each item order in the wave aggregated order to retail order.

[0045] For example, the target quantity threshold can be 3 or 2. There is no limit to the target quantity threshold here, and it can be customized according to actual needs.

[0046] Based on the above embodiments, specifically, the method further includes: when the ratio between the target order quantity and the aggregate order quantity is less than or equal to a preset ratio threshold, and the target order quantity is greater than or equal to a target quantity threshold, setting the order type of each target item order to batch order, and setting the order type of item orders in the wave aggregate order other than each target item order to retail order.

[0047] The advantage of this setup is that, since picking tasks are typically performed on a wave-based order basis, if a wave-based order contains both bulk and retail orders, some orders may require RFID tag collection for picking, while others may not. This increases the complexity of the picking task, reduces picking efficiency, and raises the picking error rate. This embodiment avoids this situation as much as possible by setting order types based on wave-based orders, ensuring the overall outbound efficiency of the warehousing system while minimizing the picking error rate.

[0048] S120. When the order type is a batch order, perform a picking operation to obtain the picked items based on the minimum inventory unit and the quantity of items in the item order.

[0049] The minimum stock keeping unit (SKU) is the basic unit for the quantity of goods entering and leaving the inventory. It includes a category of goods with specific natural and social attributes. For example, natural attributes include, but are not limited to, brand, model, configuration, color, capacity, production date, purpose and price, etc., while social attributes include, but are not limited to, inventory method or sales form, etc.

[0050] In one specific embodiment, a picking operation is performed to obtain picked items based on the minimum inventory unit and the quantity of items in the item order, including: performing a destocking operation on the storage items in at least one target source storage location corresponding to the minimum inventory unit in the item order based on the quantity of items in the item order; and placing each picked item obtained from the destocking operation on the verification platform location corresponding to the item order.

[0051] Specifically, each pre-set loading dock location used for verification is associated with at least one pre-set source warehouse location. When all picked items come from the same target source warehouse location, each picked item is placed on any pre-set loading dock location associated with that target source warehouse location. This pre-set loading dock location is the verification loading dock location corresponding to the item order. When all picked items come from multiple target source warehouse locations, each picked item is placed on any pre-set loading dock location associated with any one of the target source warehouse locations. This pre-set loading dock location is the verification loading dock location corresponding to the item order.

[0052] S130. Obtain the RFID tag information corresponding to each picked item collected by the RFID collection device.

[0053] RFID technology is an automatic identification technology that uses radio frequency (RF) for non-contact, two-way data communication. It reads and writes electronic tags using RF to identify targets and exchange data. RFID data collection equipment typically consists of three parts: electronic tags, a reader, and a data management module. Specifically, electronic tags identify items, exchange data with the reader via radio waves, and the reader transmits read / write commands from the data management module to the electronic tags. The reader then sends the data returned by the electronic tags to the data management module, which is responsible for storing, managing, and controlling the data information from the electronic tags.

[0054] For example, RFID tag information can be used to identify information such as the size, name, expiration date, and origin storage location of an item.

[0055] S140. Based on the information of each RFID tag, perform a composite verification operation to obtain the composite verification result corresponding to the item order.

[0056] In this embodiment, the composite verification operation is used to characterize the verification operation that combines picking verification and review verification.

[0057] In one specific embodiment, a composite verification operation is performed based on each RFID tag information to obtain the composite verification result corresponding to the item order. This includes: for each RFID tag information, determining the composite verification status corresponding to the RFID tag information according to the storage status and tag source warehouse location; and setting the composite verification result corresponding to the item order as successful if the composite verification status corresponding to each RFID tag information is successful.

[0058] Specifically, the tag source storage location is used to characterize the preset source storage location where the picked items corresponding to the RFID tag information are stored.

[0059] In one specific embodiment, the composite verification status corresponding to the RFID tag information is determined based on the storage status and tag source storage location of the RFID tag information. This includes: obtaining the set of associated source storage locations corresponding to the verification platform location where each picked item is placed; if the storage status is in stock and the tag source storage location exists in the set of associated source storage locations, the composite verification status corresponding to the RFID tag information is set to successful verification, and the storage status corresponding to the RFID tag information is updated to the delisted status.

[0060] Specifically, the associated source storage location set includes at least one associated source storage location that is associated with the verification platform location.

[0061] Based on the above embodiments, specifically, determining the composite verification status corresponding to the RFID tag information according to the storage status and tag source storage location of the RFID tag information further includes: setting the composite verification status corresponding to the RFID tag information to verification failure when the storage status is "out of stock" or the tag source storage location does not exist in the associated source storage location set.

[0062] Specifically, when the composite verification status is "verification failed", a verification failure message generated based on the storage status and / or tag source storage location will be output and displayed. For example, the verification failure message may be "The storage status of the xxx RFID tag information on the verification platform is inaccurate", or "The tag source storage location of the xxx RFID tag information on the verification platform does not belong to the associated source storage location".

[0063] In another specific embodiment, the composite verification status corresponding to the RFID tag information is determined based on the storage status corresponding to the RFID tag information and the tag source storage location. This includes: obtaining the number of items that are in stock in the tag source storage location and the associated source storage location set corresponding to the verification platform location where each picked item is placed; if the storage status is in stock, the tag source storage location exists in the associated source storage location set, and the number of items that can be picked is greater than or equal to 1, the composite verification status corresponding to the RFID tag information is set to successful verification; and the storage status corresponding to the RFID tag information is updated to the delisted status.

[0064] For example, assuming there are 4 RFID tag information entries, and before the composite verification operation is performed, the number of items that are in stock and ready for picking in the tag source storage location is 5, if the composite verification status corresponding to the first RFID tag information is successful, then when determining the composite verification status corresponding to the second RFID tag information, the number of items ready for picking corresponding to the second RFID tag information is 4. If the composite verification status corresponding to the first RFID tag information is unsuccessful, then when determining the composite verification status corresponding to the second RFID tag information, the number of items ready for picking corresponding to the second RFID tag information is 5.

[0065] Based on the above embodiments, specifically, determining the composite verification status corresponding to the RFID tag information according to the storage status and tag source storage location of the RFID tag information further includes: setting the composite verification status corresponding to the RFID tag information to verification failure when the storage status is "out of stock", or the tag source storage location does not exist in the associated source storage location set, or the number of items that can be picked is less than 1.

[0066] Based on the above embodiments, specifically, the composite verification operation is performed based on each RFID tag information to obtain the composite verification result corresponding to the item order, and further includes: if there is at least one RFID tag information whose composite verification status is verification failure, the composite verification result corresponding to the item order is set to composite verification failure.

[0067] S150. If the composite verification result is successful, perform the outbound operation on each picked item.

[0068] Based on the above embodiments, specifically, the method further includes: if the composite verification result is a composite verification failure, performing a return operation on each picked item at the verification platform location based on the minimum inventory unit, the quantity of items, and each target source warehouse location.

[0069] In existing technologies, since the RFID tag information of each item is collected during the picking process, the RFID tag information of each item needs to be collected again during the restocking process. However, in this embodiment of the invention, picking is based on the minimum inventory unit, so the restocking process also only needs to be performed based on the minimum inventory unit. Existing technologies collect RFID tag information once each during the picking, verification, and restocking processes, while this embodiment of the invention only collects RFID tag information once during the verification process. Therefore, this embodiment of the invention improves the efficiency of item restocking and further enhances the overall management efficiency of the warehousing system.

[0070] Figure 2 This is a flowchart illustrating a specific example of an item outbound method provided in an embodiment of the present invention. Specifically, it determines whether the item order type is a batch order. If so, it performs a non-RFID picking operation and an RFID composite verification. The non-RFID picking operation specifically involves performing a picking operation based on the minimum inventory unit and item quantity in the item order to obtain the picked items. The RFID composite verification specifically involves acquiring the RFID tag information corresponding to each picked item collected by the RFID acquisition device, and performing a composite verification operation based on the RFID tag information to obtain the composite verification result corresponding to the item order.

[0071] If the order type is retail, determine whether it falls under the RFID warehouse picking task. If so, execute RFID picking and picking verification. This involves acquiring the RFID tag information corresponding to each item in each storage location collected by the RFID collection device to complete the picking operation and obtain the picked items. Based on the RFID tag information, execute the picking verification operation to obtain the picking verification result for the item order. If the picking verification result is successful, use the RFID re-verification mode. This involves acquiring the RFID tag information corresponding to each picked item collected by the RFID collection device and executing the re-verification operation based on the RFID tag information to obtain the re-verification result for the item order.

[0072] If a retail order is not part of an RFID warehouse picking task, a non-RFID picking operation and picking verification are performed. This involves picking the items based on the minimum inventory unit and quantity in the order, and then performing a picking verification operation based on the minimum inventory unit to obtain the corresponding picking verification result. If the picking verification result is successful, a non-RFID verification check is performed, which involves performing a verification check based on the minimum inventory unit corresponding to the order to obtain the corresponding verification result.

[0073] The technical solution of this embodiment, for item orders of the order type of batch order, performs a picking operation based on the minimum inventory unit and the quantity of items in the item order to obtain the picked items. In the verification stage, the RFID tag information of the picked items is collected once. Based on the RFID tag information, a composite verification operation is performed to obtain the composite verification result corresponding to the item order. If the composite verification result is successful, the picked items are processed for outbound. This solves the problem of the large amount of manpower required for collecting tag information at multiple levels and times, reduces the number of times RFID tag information is collected in the outbound process, reduces labor costs, and improves the outbound efficiency of the warehousing system.

[0074] Figure 3 This is a flowchart of another item dispatching method provided in one embodiment of the present invention. This embodiment further refines the "performing a picking operation to obtain picked items based on the minimum inventory unit and item quantity in the item order" in the above embodiment. For example... Figure 3 As shown, the method includes:

[0075] S210. In response to the detection of an item order, obtain the order type of the item order.

[0076] S220. When the order type is a batch order, based on the quantity of items in the item order, perform a delisting operation on at least one storage location in the target source warehouse corresponding to the smallest inventory unit in the item order.

[0077] In this embodiment, S210-S220 correspond to the same or similar implementation methods of the corresponding technical features in the above embodiments, and will not be described again in this embodiment.

[0078] S230. Obtain the verification platform location corresponding to the item order.

[0079] Specifically, the preset platform location used for verification is associated with at least one preset source storage location. In one specific embodiment, obtaining the verification platform location corresponding to the item order includes: using a preset platform location that is associated with any target source storage location and is in an unoccupied state as the verification platform location corresponding to the item order.

[0080] In another specific embodiment, the method further includes: when the ratio between the number of target orders and the number of aggregated orders is greater than a preset ratio threshold, the wave aggregated order is used as the wave aggregated order; correspondingly, the verification platform position corresponding to the item order is obtained, including: obtaining a preset platform position that is associated with any target source storage position corresponding to any smallest inventory unit in the wave aggregated order and whose occupancy status is unoccupied as the verification platform position, and using the verification platform position as the verification platform position corresponding to each item order in the wave aggregated order.

[0081] In this embodiment, each picking item in each item order within the wave collection order is placed on the same verification platform. The advantage of this arrangement is that it ensures the separation of bulk orders and retail orders while avoiding the occupancy of too many pre-set platform spaces when the number of bulk orders is excessive.

[0082] Based on the above embodiments, after performing a de-shelf operation on the storage items in at least one target source storage location corresponding to the minimum inventory unit in the item order based on the item quantity in the item order, the method further includes: in response to detecting an order cancellation instruction, treating the item order corresponding to the order cancellation instruction as an abnormal order; and if the abnormal order is a batch order, performing a return-to-shelf operation on each picked item in the verification platform location based on the minimum inventory unit, item quantity, and each target source storage location.

[0083] The advantage of this setup is that it allows for the registration of abnormal orders during the outbound process, enabling timely return to the warehouse and reducing the outbound rate of abnormal orders, thereby further improving the outbound management process of the warehousing system.

[0084] In this embodiment, regardless of whether the warehousing system enables platform overlap positioning, each picking item in a batch order is placed on an unoccupied preset platform position. Platform overlap positioning indicates that picking items corresponding to different item orders or picking items corresponding to different batch orders can be placed on the same preset platform position.

[0085] S240. Place each picked item obtained from the destocking operation on the verification platform and set the platform attribute of the verification platform to batch platform.

[0086] S250. For each verification platform position, if the platform position attribute of the verification platform position is a batch platform position, obtain the RFID tag information corresponding to each picked item on the verification platform position collected by the RFID collection device.

[0087] In the verification process, each verification platform is categorized based on its platform attributes. For each verification platform, if the platform attribute is a batch platform, the RFID tag information corresponding to each picked item on the verification platform is obtained from the RFID data collection device. If the platform attribute is a retail platform, for each item order corresponding to the verification platform, it is determined whether the item order belongs to an RFID warehouse picking task. If so, the RFID tag information corresponding to each picked item on the verification platform is obtained from the RFID data collection device; otherwise, the minimum inventory unit corresponding to each picked item is obtained.

[0088] In one specific embodiment, obtaining the RFID tag information corresponding to each picked item at the verification platform collected by the RFID collection device includes: when the package attribute of the item order is non-package and the item attribute corresponding to the minimum inventory unit is non-serial number controlled item, obtaining the RFID tag information corresponding to each picked item at the verification platform collected in batches by the RFID collection device; when the package attribute of the item order is package, or the item attribute corresponding to the minimum inventory unit is serial number controlled item, obtaining the RFID tag information of the picked item collected by the RFID collection device for each picked item at the verification platform, and binding the RFID tag information with the package identifier and / or serial number corresponding to the picked item.

[0089] Specifically, when the order's package attribute is "non-package" and the smallest inventory unit's item attribute is "non-serial number controlled item," it means that only RFID tag information needs to be collected for picking, making batch collection suitable. When the order's package attribute is "package," or the smallest inventory unit's item attribute is "serial number controlled item," it means that after collecting the RFID tag information of the picking item, the RFID tag information also needs to be bound to the package identifier and / or serial number; therefore, batch collection is not suitable.

[0090] The advantage of this setup is that it further improves the efficiency of RFID tag information collection, thereby further improving the overall outbound efficiency of the warehousing system.

[0091] Based on the above embodiments, specifically, when the order type is a retail order, obtaining the verification platform location corresponding to the item order includes: determining whether platform location overlap positioning is enabled; if so, using a preset platform location that is associated with any target source warehouse location, has an occupied status, and has a platform location attribute of retail platform location as the verification platform location for the item order; if not, using a preset platform location that is associated with any target source warehouse location and has an unoccupied status as the verification platform location for the item order; setting the occupied status of the verification platform location to occupied, and setting the platform location attribute corresponding to the verification platform location to retail platform location.

[0092] The advantage of this setup is that, since retail orders correspond to a smaller number of items, and different retail orders share the same platform slot, the occupancy rate of retail orders on the platform slot can be further reduced, thereby further ensuring the rationality of platform slot allocation.

[0093] S260. Based on the information of each RFID tag, perform a composite verification operation to obtain the composite verification result corresponding to the item order.

[0094] S270. If the composite verification result is successful, perform the outbound operation on each picked item.

[0095] S260-S270 in this embodiment are the same as those in the above embodiments. Figure 1 The S140-S150 shown are the same or similar, and will not be described again in this embodiment.

[0096] Figure 4This is a flowchart illustrating a specific example of another item dispatching method provided in an embodiment of the present invention. Specifically, it determines whether platform overlap positioning is enabled. If not, the item order is positioned to a preset platform position that is not currently occupied, a verification platform position is determined, and the platform position attribute of the verification platform position is set based on the order type of the item order. If yes, it further determines whether the order type of the item order is a batch order. If it is a batch order, the item order is positioned to a preset platform position that is not currently occupied, a verification platform position is determined, and the platform position attribute of the verification platform position is set to batch platform position. If it is a retail order, the item order is positioned to a preset platform position that is currently occupied and has a platform position attribute of retail platform position, and a verification platform position is determined.

[0097] For batch orders, determine whether the batch order is an abnormal order. If it is, use the non-RFID return mode, that is, perform the return operation based on the smallest inventory unit of the abnormal order. If not, perform non-RFID picking operation and RFID composite verification.

[0098] For retail orders, determine whether the order is an abnormal order. If so, based on the result of whether the abnormal order belongs to an RFID warehouse picking task, either a non-RFID return mode or an RFID return mode is adopted. The non-RFID return mode means performing the return operation based on the smallest inventory unit of the abnormal order. The RFID return mode means acquiring the RFID tag information corresponding to each picked item collected by the RFID collection device and performing the return operation based on this RFID tag information. If not, based on the result of whether the abnormal order belongs to an RFID warehouse picking task, either a non-RFID picking verification and review verification mode or an RFID picking verification and review verification mode is adopted.

[0099] The technical solution of this embodiment, based on the quantity of items in the item order, performs a destocking operation on at least one target source storage location corresponding to the smallest inventory unit in the item order, obtains the verification platform location corresponding to the item order, places each picked item obtained from the destocking operation on the verification platform location, and sets the platform location attribute of the verification platform location to a batch platform location. This solves the problem of indistinguishable mixed placement of picked items of different order types on the platform location, and achieves the purpose of distinguishing between batch orders and retail orders. In the verification process, each picked item on the batch platform location adopts the same composite verification mode, reducing the complexity and error rate of the verification process, thereby further improving the outbound efficiency of the warehousing system.

[0100] Figure 5 This is a schematic diagram of the structure of an item dispensing device according to an embodiment of the present invention. Figure 5As shown, the device includes: an order type acquisition module 310, a picking operation execution module 320, an RFID tag information acquisition module 330, a composite verification result determination module 340, and an outbound operation execution module 350.

[0101] The order type acquisition module 310 is used to acquire the order type of the item order in response to the detection of an item order.

[0102] The picking operation execution module 320 is used to perform picking operations to obtain picked items when the order type is a batch order, based on the minimum inventory unit and the quantity of items in the item order;

[0103] The RFID tag information acquisition module 330 is used to acquire the RFID tag information corresponding to each picked item collected by the RFID acquisition device.

[0104] The composite verification result determination module 340 is used to perform composite verification operations based on the information of each RFID tag to obtain the composite verification result corresponding to the item order; wherein, the composite verification operation is used to characterize the verification operation that integrates picking verification and review verification.

[0105] The outbound operation execution module 350 is used to perform outbound operations on each picked item when the composite verification result is successful.
