[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatus.

[0035] Figure 1 This is a flowchart of a method for removing items from a warehouse provided by an embodiment of the present invention. This embodiment is applicable to the removal of ordered items from a storage system, and is particularly applicable to batch removal orders. This method can be executed by an item removal device, which can be implemented in the form of hardware and / or software, and can be configured in a terminal device. Figure 1 As shown, the method includes:

[0036] S110: In response to detecting an item order, obtaining an order type of the item order.

[0037] Specifically, the order type is defined according to the quantity of the ordered items in the item order. In this embodiment, the order type of the item order is a batch order or a retail order. Exemplarily, the batch order is usually a ToB (To Business) order, and the retail order is usually a ToC (To Consumer) order.

[0038] In a specific embodiment, obtaining the order type of an item order includes: obtaining the number of items in the item order; determining whether the number of items is greater than a preset quantity threshold, and 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] Exemplarily, the preset quantity threshold may be 20 pieces or 30 pieces. There is no limitation on the preset quantity threshold here, and the user may customize the setting according to actual needs.

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

[0041] Specifically, the wave collection list contains at least two item orders corresponding to one picking task. When the warehousing system detects multiple item orders, it usually takes a certain number of item orders as a wave collection list, plans the picking path according to the source storage locations corresponding to each item order in the wave collection list, and the picking personnel or picking equipment perform the picking task based on the picking path.

[0042] Exemplarily, the preset quantity threshold may be 20 or 30 pieces, and the preset ratio threshold may be 80% or 90%. There is no limitation on the preset quantity threshold and the preset ratio threshold, and the user may customize the settings according to actual needs.

[0043] For example, assuming that the wave collection order contains item order 1, item order 2 and item order 3, the item quantities corresponding to item order 1, item order 2 and item order 3 are 50, 2 and 30 respectively, the preset quantity threshold is 20, and the preset ratio threshold is 50%. Then, item order 1 and item order 3 are both target item orders, the collection order quantity is 3, the target order quantity is 2, and the ratio between the target order quantity and the collection order quantity is greater than 50%. Accordingly, item order 1, item order 2 and item order 3 are all set as batch orders.

[0044] On the basis of the above embodiments, specifically, the method also includes: when the ratio between the target order quantity and the collective order quantity is less than or equal to a preset ratio threshold, and the target order quantity is less than the target quantity threshold, the order types corresponding to each item order in the wave collection order are set to retail orders.

[0045] Exemplarily, the target quantity threshold may be 3 or 2. The target quantity threshold is not limited here and can be customized according to actual needs.

[0046] On the basis of the above embodiments, specifically, the method also includes: when the ratio between the target order quantity and the collective order quantity is less than or equal to a preset ratio threshold, and the target order quantity is greater than or equal to the target quantity threshold, the order type of each target item order is set to a batch order, and the order type of the item orders in the wave collection order except for the target item orders is set to a retail order.

[0047] The advantage of such a setting is that since the picking task is usually carried out in units of wave collection orders, if there are both bulk orders and retail orders in a wave collection order, when executing the picking task based on the wave collection order, some of the item orders will need to collect RFID tag information for picking, while other item orders will not need to collect RFID tag information for picking, which will increase the complexity of the picking task, reduce the picking efficiency, and increase the picking error rate. This embodiment avoids the occurrence of the above situation as much as possible by setting the order type based on the wave collection order, while ensuring the overall outbound efficiency of the warehousing system and reducing the picking error rate as much as possible.

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

[0049] The minimum stock keeping unit (SKU) is the basic unit of inventory in and out dosage, which contains item categories with specific natural attributes and social attributes. For example, natural attributes include but are not limited to brand, model, configuration, color, capacity, production date, purpose and price, etc., and social attributes include but are not limited to inventory method or sales form, etc.

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

[0051] Specifically, the preset platform position for verification is associated with at least one preset source storage position. When the picked items come from the same target source storage position, the picked items are placed on any preset platform position associated with the target source storage position, and the preset platform position is the verification platform position corresponding to the item order. When the picked items come from multiple target source storage positions, the picked items are placed on any preset platform position associated with any target source storage position, and the preset platform position is the verification platform position corresponding to the item order.

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

[0053] Among them, RFID technology is an automatic identification technology that uses wireless radio frequency to perform non-contact two-way data communication and uses wireless radio frequency to read and write electronic tags, thereby achieving the purpose of identifying targets and exchanging data. RFID acquisition equipment usually consists of three parts: electronic tags, readers and writers, and data management modules. Specifically, electronic tags are used to identify items, and electronic tags exchange data with readers and writers through radio waves. The reader and writer can transmit the read and write commands of the data management module to the electronic tags, and then transmit the data returned by the electronic tags to the data management module. The data management module is responsible for completing the storage, management and control of the data information of the electronic tags.

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

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

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

[0057] In a specific embodiment, based on each RFID tag information, a composite verification operation is performed to obtain a composite verification result corresponding to the item order, including: for each RFID tag information, according to the storage status corresponding to the RFID tag information and the tag source storage location, determining the composite verification status corresponding to the RFID tag information; when the composite verification statuses corresponding to each RFID tag information are all verified successfully, the composite verification result corresponding to the item order is set to composite verification success.

[0058] Specifically, the tag source storage location is used to represent a preset source storage location for storing the picked items corresponding to the RFID tag information.

[0059] In a specific embodiment, the composite verification status corresponding to the RFID tag information is determined according to the storage status and the tag source storage location corresponding to the RFID tag information, including: obtaining the associated source storage location set corresponding to the review platform location where each picked item is placed; when the storage status is in-stock status and the tag source storage location exists in the associated source storage location set, the composite verification status corresponding to the RFID tag information is set to verification success, and the storage status corresponding to the RFID tag information is updated to the removed from shelf status.

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

[0061] On the basis of the above embodiments, specifically, the composite verification status corresponding to the RFID tag information is determined according to the storage status and the tag source storage location corresponding to the RFID tag information, and also includes: when the storage status is off-shelf or the tag source storage location does not exist in the associated source storage location set, the composite verification status corresponding to the RFID tag information is set to verification failure.

[0062] Specifically, when the composite verification status is verification failure, the verification failure prompt information generated based on the storage status and / or the tag source storage location will be output and displayed. For example, the verification failure prompt information may be "The storage status of the xxxRFID tag information on the verification platform location is inaccurate", or the verification failure prompt information may be "The tag source storage location of the xxxRFID tag information on the verification platform location 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 and the tag source storage location corresponding to the RFID tag information, including: obtaining the number of items that can be picked in the storage location whose storage status is in-stock status in the tag source storage location and the associated source storage location set corresponding to the review platform location where each picked item is placed; when the storage status is in-stock status, and 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 verification success; and the storage status corresponding to the RFID tag information is updated to be off-shelf status.

[0064] For example, assuming that the number of RFID tag information is 4, before the composite verification operation is performed, the number of storage location items that can be picked in the tag source storage location with a storage status of in-stock is 5, if the composite verification status corresponding to the first RFID tag information is successful verification, then when determining the composite verification status corresponding to the second RFID tag information, the number of items that can be picked corresponding to the second RFID tag information is 4; if the composite verification status corresponding to the first RFID tag information is failed verification, then when determining the composite verification status corresponding to the second RFID tag information, the number of items that can be picked corresponding to the second RFID tag information is 5.

[0065] On the basis of the above embodiments, specifically, the composite verification status corresponding to the RFID tag information is determined according to the storage status and the tag source storage location corresponding to the RFID tag information, and also includes: when the storage status is off-shelf, 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, the composite verification status corresponding to the RFID tag information is set to verification failure.

[0066] On the basis of the above embodiment, specifically, based on each RFID tag information, a composite verification operation is performed to obtain a composite verification result corresponding to the item order, and also includes: when there is at least one RFID tag information corresponding to which the composite verification status is a verification failure, the composite verification result corresponding to the item order is set to a composite verification failure.

[0067] S150: When the composite verification result is successful, a warehouse-out operation is performed on each picked item.

[0068] On the basis of the above embodiment, specifically, the method further includes: when the composite verification result is composite verification failure, based on the minimum inventory unit, the number of items and each target source storage location, performing a return operation on each picked item on the review platform location.

[0069] In the prior art, since the RFID tag information of each item is collected during the picking process, it is necessary to collect the RFID tag information of each item again to perform the return operation in the return process. However, in the embodiment of the present invention, picking is performed based on the minimum inventory unit in the picking process, so in the return process, it is also only necessary to perform the return operation based on the minimum inventory unit. In the prior art, RFID tag information is collected once in the picking process, the review process, and the return process, respectively, while the embodiment of the present invention only collects RFID tag information once in the review process. Therefore, while improving the efficiency of returning items to the shelves, the embodiment of the present invention further improves the overall management efficiency of the warehousing system.

[0070] Figure 2 The flowchart is a specific example of a method for removing items from warehouse provided by an embodiment of the present invention. Specifically, it is determined whether the order type of the item order is a batch order. If so, a non-RFID picking operation and an RFID composite check are performed, wherein the non-RFID picking operation is specifically based on the minimum inventory unit and the number of items in the item order, and a picking operation is performed to obtain the picked items. The RFID composite check is specifically to obtain the RFID tag information corresponding to each picked item collected by the RFID collection device, and based on each RFID tag information, a composite check operation is performed to obtain a composite check result corresponding to the item order.

[0071] If the order type of the item order is a retail order, determine whether the retail order belongs to the RFID inter-warehouse picking task. If so, perform the RFID picking operation and picking verification, that is, obtain the RFID tag information corresponding to each storage location item collected by the RFID acquisition device to complete the picking operation to obtain the picked items, and based on each RFID tag information, perform the picking verification operation to obtain the picking verification result corresponding to the item order. If the picking verification result is that the picking verification is successful, the RFID review verification mode is adopted, that is, obtain the RFID tag information corresponding to each picked item collected by the RFID acquisition device, and based on each RFID tag information, perform the review verification operation to obtain the review verification result corresponding to the item order.

[0072] If the retail order does not belong to the RFID inter-warehouse picking task, the non-RFID picking operation and picking verification are performed, that is, based on the minimum inventory unit and the number of items in the item order, the picking operation is performed to obtain the picked items, and based on the minimum inventory unit, the picking verification operation is performed to obtain the picking verification result corresponding to the item order. If the picking verification result is that the picking verification is successful, the non-RFID review and verification mode is adopted, that is, based on the minimum inventory unit corresponding to the item order, the review and verification operation is performed to obtain the review and verification result corresponding to the item order.

[0073] The technical solution of the present embodiment is to perform a picking operation to obtain picked items based on the minimum inventory unit and the item quantity in the item order for an item order whose order type is a batch order, collect the RFID tag information of the picked items once in the review stage, perform a composite verification operation based on the RFID tag information to obtain a composite verification result corresponding to the item order, and perform an outbound operation on the picked items when the composite verification result is that the composite verification is successful, thereby solving the problem of consuming a lot of manpower for multi-layer and multiple label information collection, reducing the number of times RFID tag information is collected in the outbound flow of items, reducing labor costs, and improving the outbound efficiency of the warehousing system.

[0074] Figure 3 This is a flow chart of another method for removing items from a warehouse provided by an embodiment of the present invention. This embodiment further refines the "based on the minimum inventory unit and the number of items in the item order, performing a picking operation to obtain the picked items" in the above embodiment. Figure 3 As shown, the method includes:

[0075] S210: In response to detecting an item order, obtaining an order type of the item order.

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

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

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

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

[0080] In another specific embodiment, the method also includes: when the ratio between the target order quantity and the collection order quantity is greater than a preset ratio threshold, using the wave collection order as the wave collection order; accordingly, obtaining the review platform position corresponding to the item order, including: obtaining a preset platform position that has an association relationship with any target source storage position corresponding to any minimum inventory unit in the wave collection order and whose occupancy status is unoccupied as the review platform position, and using the review platform position as the review platform position corresponding to each item order in the wave collection order.

[0081] In this embodiment, each picked item in each item order in the wave collection list is placed on the same review platform. The advantage of this arrangement is that while ensuring the distinction between bulk orders and retail orders, it avoids the situation where too many preset platform positions are occupied when the number of bulk orders is too large.

[0082] On the basis of the above embodiment, after performing a delisting operation on the storage location items on 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 also includes: in response to detecting an order cancellation instruction, treating the item order corresponding to the order cancellation instruction as an abnormal order; in the case that the order type of the abnormal order is a batch order, performing a return operation on each picked item on the review platform based on the minimum inventory unit, the item quantity and each target source storage location.

[0083] The advantage of this setting is that abnormal orders in the outbound process can be registered as abnormal, and the items can be returned to the shelves in a timely manner, reducing the outbound rate of items for abnormal orders, thereby further improving the outbound management process of the warehousing system.

[0084] In this embodiment, regardless of whether the warehouse system opens the platform overlap positioning, each picked item in the batch order is placed on an unoccupied preset platform position. The platform overlap positioning is used to indicate that each picked item corresponding to different item orders or each picked item corresponding to different wave collection orders can be placed on the same preset platform position.

[0085] S240: Place each picked item obtained by the unloading operation on a verification platform position, and set the platform position attribute of the verification platform position to a batch platform position.

[0086] S250. For each review platform location, when the platform location attribute of the review platform location is a batch platform location, obtain the RFID tag information corresponding to each picking item on the review platform location collected by the RFID collection device.

[0087] In the review phase, each review platform is classified based on its platform attributes. For each review platform, when the platform attribute of the review platform is a batch platform, obtain the RFID tag information corresponding to each picked item on the review platform collected by the RFID collection device. When the platform attribute of the review platform is a retail platform, for each item order corresponding to the review platform, determine whether the item order belongs to the RFID inter-warehouse picking task. If so, obtain the RFID tag information corresponding to each picked item on the review platform collected by the RFID collection device. If not, obtain the minimum inventory unit corresponding to each picked item.

[0088] In a specific embodiment, the RFID tag information corresponding to each picking item on the review platform collected by the RFID acquisition device is obtained, including: when the package attribute of the item order is non-package and the item attribute corresponding to the minimum inventory unit is a non-serial number controlled item, the RFID tag information corresponding to each picking item on the review platform collected in batches by the RFID acquisition device is obtained; when the package attribute of the item order is a package, or the item attribute corresponding to the minimum inventory unit is a serial number controlled item, for each picking item on the review platform, the RFID tag information of the picking item collected by the RFID acquisition device is obtained, and the RFID tag information is bound to the package identification and / or serial number corresponding to the picking item.

[0089] Specifically, when the parcel attribute of the item order is non-parcel, and the item attribute of the minimum inventory unit is a non-serial number controlled item, it means that only the RFID tag information needs to be collected for the picked items, and it is suitable for batch collection. When the parcel attribute of the item order is a parcel, or the item attribute of the minimum inventory unit is a serial number controlled item, it means that after collecting the RFID tag information of the picked items, the RFID tag information needs to be bound to the parcel identification and / or serial number, so batch collection is not applicable.

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

[0091] On the basis of the above embodiments, specifically, when the order type is a retail order, obtaining the review platform position corresponding to the item order includes: determining whether the platform position overlapping positioning is turned on, if so, using a preset platform position that has an association relationship with any target source storage position and whose occupancy status is occupied and whose platform position attribute is a retail platform position as the review platform position for the item order; if not, using a preset platform position that has an association relationship with any target source storage position and whose occupancy status is unoccupied as the review platform position for the item order; setting the occupancy status of the review platform position to occupied, and setting the platform position attribute corresponding to the review platform position to a retail platform position.

[0092] The advantage of this setting is that, since the number of items corresponding to a retail order is small, different retail orders share the same platform position, which can further reduce the occupancy rate of the platform positions by retail orders, thereby further ensuring the rationality of the platform position allocation.

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

[0094] S270: When the composite verification result is successful, perform a warehouse-out operation on each picked item.

[0095] S260-S270 in this embodiment are similar to those in the above embodiment. Figure 1 S140 - S150 shown in FIG. 1 are identical or similar to each other, and will not be described in detail in this embodiment.

[0096] Figure 4A flowchart of a specific example of another method for removing items from the warehouse provided by an embodiment of the present invention. Specifically, determine whether the overlapping positioning of the platform position is turned on. If not, locate the item order to a preset platform position with an occupancy status of unoccupied, determine the review platform position, and set the platform position attribute of the review platform position based on the order type of the item order. If yes, continue to determine whether the order type of the item order is a batch order. If it is a batch order, locate the item order to a preset platform position with an occupancy status of unoccupied, determine the review platform position, and set the platform position attribute of the review platform position to a batch platform position. If it is a retail order, locate the item order to a preset platform position with an occupancy status of occupied and a platform position attribute of a retail platform position, and determine the review platform position.

[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 minimum inventory unit of the abnormal order. If not, perform non-RFID picking operation and RFID composite verification.

[0098] For retail orders, determine whether the retail order is an abnormal order. If so, based on the judgment result of whether the abnormal order belongs to the RFID inter-warehouse picking task, adopt the non-RFID return mode or the RFID return mode, where the non-RFID return mode means performing the return operation based on the minimum inventory unit of the abnormal order, and the RFID return mode means obtaining the RFID tag information corresponding to each picked item collected by the RFID collection device, and performing the return operation based on each RFID tag information. If not, based on the judgment result of whether the abnormal order belongs to the RFID inter-warehouse picking task, adopt the non-RFID picking verification and rechecking mode or the RFID picking verification and rechecking mode.
