Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This disclosure claims priority to Chinese Patent Application No. 202010832026.8, filed on August 18, 2020, entitled "ORDER RECHECKING DEVICE, ORDER RECHECKING SYSTEM AND ORDER RECHECKING METHOD," which is incorporated herein by reference in its entirety.

[0002] The present disclosure relates to the field of logistics management technology, and in particular to an order recheck device, an order recheck system, and an order recheck method. [Background technology]

[0003] With the rapid development of e-commerce, the number of daily orders in warehouses is increasing. Before transportation, multiple items in one order must be packed into packages and then transported by transportation staff. A common processing procedure is to generate a recheck work list based on several orders, and all items corresponding to these orders are listed on the recheck work list. A recheck operator selects items according to the items listed on the recheck work list. At this point, there are multiple items, and the items can be transported to the recheck section by a product selection vehicle to prepare for rechecking. Rechecking items in warehouses is a key part of warehouse operations. The purpose of rechecking is to separate the items listed on the recheck work list according to the order so that the multiple items listed in each order can be placed together. Generally, the multiple items listed in each order are placed in the same transaction box to prepare the items for packaging and transportation. As customers have increasingly higher demands for logistics timeliness, improving the efficiency of rechecking in warehouses has become a crucial link in improving the efficiency of the entire supply chain.

[0004] In the related art well known to the inventor, there are generally two methods for rechecking orders.

[0005] In the order recheck method, the order recheck system mainly used includes an electronic tag placed in the transaction box and an RFID (radio frequency identification) reader placed in the storage location, and the electronic tag on the transaction box, the storage location number, and the order information are separately linked, and the electronic tag is used to indicate the storage location information of the corresponding product.

[0006] In another order recheck method, each storage location in the recheck shelf is labeled with a barcode, and each transaction box is equipped with a barcode. After rechecking, the storage location barcode information, the barcode number on the transaction box, and the order information are separately linked. Each time an item is scanned, the storage location number corresponding to the item is indicated on the display screen, the item is placed in the transaction box corresponding to the recheck storage location, and then the storage location barcode is scanned for authentication. The above operation stops until all items have been rechecked. Summary of the Invention [Problem to be solved by the invention]

[0045] As shown in FIGS. 1 to 18, embodiments of the present disclosure provide an order recheck device, an order recheck system, and an order recheck method.

[0046] 1 to 12, an order re-check device 100 according to an embodiment of the present disclosure primarily includes at least one shelving unit 110. For example, as shown in FIG. 1, the order re-check device 100 includes ten shelving units 110. In some embodiments not shown, one order re-check device 100 may include fewer or more shelving units 110. For example, the number of shelving units 110 may be 1, 3, 4, 8, 12, etc.

[0047] As shown in FIGS. 1 to 8 , the shelf unit 110 mainly includes a shelf 111 and a plurality of information interaction devices 113. The shelf 111 includes a plurality of storage positions S for placing products. The plurality of information interaction devices 113 correspond one-to-one to the plurality of storage positions S, and the information interaction device 113 includes at least one of interaction units for performing information interaction with the outside. For example, at least one of the interaction units includes a first interaction unit 1131 and a second interaction unit 1132. The interaction unit includes a signal connection section that is signal-connected to the controller 200 and an information prompt section that sends prompt information according to an instruction from the controller 200.

[0048] For example, the controller may include a computer with a Warehouse Management System (WMS).

[0049] The order recheck device according to this embodiment may be used in conjunction with a controller to interact with information. The controller controls the interaction unit of the information interaction device to match the storage location according to the order in the recheck work list and send prompt information. Unlike related art, there is no need to pre-associate the electronic tag on the transaction box, the storage location number, and the order information, or to associate the barcode information of the storage location, the barcode number on the transaction box, and the order information. This helps improve rechecking flexibility and efficiency.

[0050] 1 to 8, in this embodiment, the shelf unit 110 further includes a plurality of storage location identifiers 112, and the plurality of storage location identifiers 112 correspond one-to-one to the plurality of storage locations S. The plurality of storage location identifiers 112 are arranged on shelves 111 of the shelf unit 110. Each location identifier 112 includes information corresponding to the storage location S, and may be a two-dimensional code, a barcode, a wireless tag, or the like.

[0051] In some embodiments, the shelf unit 110 further includes a shelf identifier, which includes information corresponding to the shelf unit 110 and may be a two-dimensional code, a barcode, a wireless tag, or the like.

[0052] As shown in FIGS. 1 to 8, the shelf 111 includes a frame 1111 , a shelf plate 1112 , a baffle portion 1113 , and a shroud plate 1114 .

[0053] The frame 1111 is rectangular and includes four uprights 1111A, two upper transverse end beams 1111B, two lower transverse end beams 1111B, two upper longitudinal end beams 1111C, two lower longitudinal end beams 1111C, and a number of intermediate beams 1111D located at the front and rear of the frame in each layer. One shelf plate 1112 is located on the rectangular frame surrounded by the two lower transverse end beams 1111B and the two lower longitudinal end beams 1111C. Another shelf plate 1112 is located on two opposing intermediate beams 1111D at the front and rear of each layer, respectively. The shelf plates 1112 divide the interior space of the shelf 111 into multiple storage layers.

[0054] The surrounding plate 1114 includes two side plates 1114A disposed on the left and right sides of the frame 1111, respectively, and a rear plate 1114B disposed on the rear side of the frame 1111.

[0055] 5, the upper lateral end beam 1111B at the top of the rear side of the frame 1111 includes connecting holes 1111H that are added to the shelf connecting rods of the suspension assemblies 125, described below, that are configured to suspend the shelving units 110 on the rails 122.

[0056] A baffle portion 1113 is disposed within each storage layer and configured to divide the storage layer, with the baffle portion 1113 being disposed within different storage locations S. As shown in Figures 1 and 2, 5 and 6, and 10, in some embodiments, the baffle portion 1113 is disposed between two adjacent storage locations S to separate the two storage locations, and the baffle portion 1113 is disposed in a variable position orientation to adjust the spacing between the two adjacent storage locations S.

[0057] As shown in FIG. 10 , in some embodiments, the baffle section 1113 includes a baffle 1113A, a bottom plate 1113B, and a flange plate 1113C. The bottom plate 1113B is strip-shaped and extends horizontally from the front to the rear of the frame 1111. The bottom plate 1113B is disposed on a shelf plate 1112 of the storage layer and is movable left and right. The baffle 1113A stands upright in the middle of the bottom plate 1113B and is fixedly connected to the bottom plate 1113B. The flange plate 1113C is connected to the front end of the bottom plate 1113B and extends downward from the front edge of the bottom plate 1113B. The bottom plate 1113B is disposed on the shelf plate 1112 of the shelving unit 110 and is configured to secure and support the baffle 1113A. The flange plate 1113C and the bottom plate 1113B form a right angle, and the edges of the flange plate 1113C and the bottom plate 1113B are both placed on the corresponding intermediate beam 1111D or lateral end beam 1111B for position limiting and fixing.

[0058] The baffle members 1113 are disposed on the shelf plates 1112 and are movable left and right to provide physical separation on different adjacent storage locations S. In addition, the space between each of the different adjacent storage locations S may also be adjusted appropriately. If the space required for some of the orders exceeds the capacity of the storage location S, the capacity of the storage location S corresponding to the orders is increased by moving the baffle members 1113 to better fit the space required for the items listed in the different orders.

[0059] In this embodiment, each storage layer includes only one baffle portion 1113. In some embodiments not shown, each storage layer can include more baffle portions 1113 to divide three or more storage locations S for each storage layer.

[0060] Additionally, the above-described embodiments of the present disclosure only describe baffle sections 1113 on the same storage layer, where the baffle sections adjust the spacing of the storage locations S by adjusting the width of the storage locations S. However, in some embodiments not shown, baffle sections may also be positioned between adjacent upper and lower storage locations S, where the spacing of the storage locations is adjusted by adjusting the height of the storage locations S.

[0061] 9, in some embodiments, each information interaction device 113 includes two interaction units: a first interaction unit 1131 and a second interaction unit 1132. The first interaction unit includes a first display screen 1131A and a first button 1131B, and the second interaction unit includes a second display screen 1132A and a second button 1132B. In addition, each information interaction device 113 may also include a function button set 1133. For example, the function button set 1133 may include a power button, an up / down adjustment button, etc.

[0062] In this embodiment, each information interaction device 113 includes two interaction units and can implement a one-person operation mode or a two-person operation mode. In the one-person operation mode, only one interaction unit of the information interaction device 113 is enabled. In the two-person operation mode, the first interaction unit 1131 and the second interaction unit 1132 are enabled.

[0063] Each information interaction device 113 is equipped with two (or more) interaction units to help implement order rechecking through flexible switching between one-person operation mode and two-person operation mode according to different operation intensity (if the information interaction device includes more interaction units, there may be a multi-person operation mode with four or more people), thereby reducing the overall cost.

[0064] The setting mode of the information interaction device is not unique, and any information interaction device that can meet the functional requirements during order checking can be used. For example, the interaction unit of the interaction device 113 may include a display light, a buzzer, a broadcasting device, and other information presentation devices.

[0065] As shown in Figures 1 to 4, in some embodiments, the order recheck device 100 further includes a shelf shifting device 120 configured to drive the shelf unit 110 to move along a predetermined route.

[0066] The shelf shifting device 120 is arranged to drive the shelf unit 110 to move along a predetermined route, so that the shelf unit 110 loaded with products can be automatically transferred to another operating section for subsequent operations. For example, the shelf unit can be transferred to a packing section for packing, or the shelf unit 110 unloaded with products can be automatically transferred from another operating section to the recheck section for rechecking a new recheck work list. This therefore increases the automatic level and deployment speed of the order recheck device, helping to improve rechecking efficiency.

[0067] 1 to 4, the shelf shifting device 120 includes a drive device 121 and a rail 122. The drive device 121 is drivingly connected to the shelving unit 110. The shelving unit 110 is disposed on the rail 122 and moves along a predetermined route determined by the rail 122. The drive device 121 may be various devices capable of driving the shelving unit 110 to move along the predetermined route, such as a drive motor.

[0068] The shelf shifting device is configured as a combination of a drive device and a rail, and the movement path of the shelf unit 110 does not need to be specifically controlled. This helps to appropriately control the loading or unloading position of the shelf unit, thereby simplifying the control process.

[0069] As shown in Figures 1 to 4, in some embodiments, the rail 122 is a closed rail. The enclosing shape of the closed rail may be set according to field requirements. For example, such an enclosing shape may be oval, circular, etc. Indeed, in some embodiments not shown, the rail may be an open-loop rail, in which case the shelving unit may reciprocate along the rail.

[0070] The cross-sectional shape of the closure rail may be set according to the carrying requirements, for example, the closure rail may be an H-shaped rail, a grooved rail, etc.

[0071] The rails are configured as closed rails so that the shelving units 110 move periodically within the associated operating sections, which helps to appropriately position the associated operating sections along the closed rails, reduce the space occupied by the order recheck device and the entire order recheck system including the order recheck device, and shorten the route required to complete the loading and unloading of items once by the order recheck device.

[0072] As shown in Figures 1 to 4, rails 122 may be positioned above shelving units 110, with shelving units 110 suspended from rails 122, thereby forming the order recheck device as a suspended recheck device.

[0073] In some embodiments not shown, rails 122 may also be positioned below shelving unit 110 , with rails 122 providing support for shelving unit 110 .

[0074] In some embodiments, the order recheck device 100 further includes a transmission device 123, which is connected between the drive device 121 and the shelf unit 110, and the drive device 121 drives the shelf unit 110 to move via the transmission device 123.

[0075] The transmission device 123 is arranged to more flexibly select and arrange the shelf shifting device 120 and the driving device 121. This also helps to drive multiple shelf units 110 to move by using the same driving device 121 according to a set rule, for example, to drive multiple shelf units 110 to move synchronously.

[0076] 1-4, in some embodiments, the transmission device 123 includes a drive sprocket (not numbered because it is hidden from view by the rail), a driven sprocket 1234, and a transmission chain 1233. The drive sprocket is connected to the output shaft of the driver 121. The rotational axis of the driven sprocket 1234 and the rotational axis of the drive sprocket are parallel and spaced apart. The transmission chain 1233 is mounted on the drive sprocket and the driven sprocket 1234 and is disposed along the rail 122, and the shelving unit 110 is connected to the transmission chain 1233.

[0077] As shown in FIGS. 1 to 4 , the order re-check device 100 includes a support frame 130, which includes a support girder, a lower connecting beam, a connecting beam, a short connecting beam, a motor mounting bracket, a fixed bottom plate, etc., and is used to support the aforementioned components of the order re-check system. A rail 122 is fixedly mounted to the top of the support frame 130, and both the drive unit 121 and the transmission device 123 are mounted on the support frame 130 or the rail 122. For example, the shelf shifting device 120 includes a shaft mounting bracket 126, which is disposed on the support frame 130, and the rotating shaft of the driven sprocket 1234 is rotatably mounted on the shaft mounting bracket 126 such that the driven sprocket 1234 is mounted on the support frame 130. The drive unit 121 and the drive sprocket are mounted on the rail 122.

[0078] As shown in FIGS. 1 to 4, 11 and 12, the shelf shifting device 120 includes a suspension assembly 125, and the shelf unit 110 is movably suspended on rails 122 via the suspension assembly 125.

[0079] As shown in FIGS. 11 and 12, in some embodiments, the suspension assembly 125 includes a guide pulley 1256 that mates with the rail 122 , and the shelving unit 110 is suspended on the rail 122 via the guide pulley 1256 .

A shaft shoulder may also be disposed between the guide pulley 1256 and the bending plate such that a corresponding outer end of the inner ring of the guide pulley 1256 abuts the shaft shoulder, helping the outer ring of the guide pulley 1256 clear surrounding structural members to smoothly rotate the outer ring of the guide pulley 1256 relative to the inner ring.

[0084] 5, in this embodiment, the frame 1111 has two connection holes 1111H. Specifically, each shelf unit 110 is connected to two suspension assemblies 125 and suspended from the rails 122 through the two suspension assemblies 125. The number of suspension assemblies 125 mated with each shelf unit 110 is not limited to two, and may be more or less depending on strength, stability, etc.

[0095] Step S530: The scanning device 300 scans the identifier of the product to be rechecked to obtain product identification information.

[0096] Step S540: The controller 200 controls the information prompt unit of the information interaction device 113 corresponding to the storage location S where the rechecked product matches the listed order according to the product identification information to send prompt information.

[0097] Step S550: Locate the item to be rechecked at storage location S from which the prompt information is sent.

[0098] In some embodiments, the order recheck method further includes step S500, in which the scanning device 300 scans the work list identifier of the recheck work list to obtain the work list information. In step S510, the controller 200 obtains the required work list information from the scanning device 300.

[0099] In some embodiments, step S520 includes the following steps:

[0100] Step S5201: The controller 200 determines the quantity of the orders in the recheck work list.

[0101] Step S5202: The controller 200 acquires shelf information obtained by scanning the shelf identifier of the idle shelf unit 110 with the scanning device 300.

[0102] Step S5203: The controller 200 checks the required number of shelf units 110 according to the order quantity and the number of storage positions of idle shelf units 110 corresponding to the shelf information, and selects a shelf unit 110.

[0103] Step S5204: The controller 200 matches each of the multiple orders in the recheck work list with a storage location S in the selected shelving unit 110.

For example, after the product to be rechecked is placed in the storage location S corresponding to the information interaction device that sends the prompt information, the verification information is sent to the controller 200 via an interaction unit of the information interaction device. For example, the verification information may be sent to the controller 200 via a touch panel, a button, or the like of the interaction unit.

[0113] In some embodiments, steps S530, S540, and S550 are repeated before any rechecked items listed on the recheck work list are rechecked.

[0114] As shown in FIG. 14, in some embodiments, the order rechecking method further includes step S560 of transporting the shelf unit 110 loaded with the rechecked items to the packing section after the items to be rechecked listed in the rechecking work list have been rechecked.

[0115] In some embodiments, in step S560, the shelf shifting device 120 drives the shelving unit 110 along a predetermined route to reach the packaging section.

[0116] In some embodiments, the shelf shifting device 120 includes a drive motor, and step S560 includes the drive motor driving the shelf unit 110 to move along a predetermined route, an encoder of the drive motor detecting whether the shelf unit 110 moves to a specified position, and if the shelf unit 110 does not move to the specified position, a motor controller controlling the drive motor to drive the shelf unit 110 to reach the specified position, and if the shelf unit 110 moves to the specified position, proceeding to step S510 to recheck the orders in the new recheck work list.

[0117] The following describes specific operational steps of the order recheck method in an embodiment of the present disclosure with reference to FIGS.

[0118] Step S510: The controller 200 acquires the work list information in the recheck work list, which includes multiple orders. The recheck operator P1 scans the recheck work list with the handheld scanning device 300 to acquire work list information, such as the work list number. The recheck operator P1 can log in to the scanning device 300 via his account number. Generally, when selection is made at the front end, the container number and the recheck work list number are linked. Therefore, after scanning the recheck work list, the scanning device 300 uploads the work list information to the controller 200, and the controller 200 acquires the work list information in the recheck work list. The scanning device 300 may be a handheld scanning device, and scanning is mainly performed by identifying barcodes or chips through a laser head, infrared head, self-sensing device, etc., provided in the scanning device.

[0119] Step S520: The controller 200 matches each of the multiple orders in the recheck work list with a storage location S. The controller 200 obtains shelf information obtained when the scanning device 300 scans the shelf identifier of an idle shelf unit 110. The controller 200 checks the required number of shelf units 110 and selects a shelf unit 110 according to the number of storage locations of the idle shelf unit 110 corresponding to the order quantity and the shelf information. It is determined whether the number of storage locations in the idle shelf unit 110 is greater than or equal to the number of orders in the recheck work list. If the result of the determination is no, more shelf units 110 are waiting to release goods. Thereafter, it is again determined whether the number of storage locations in the idle shelf unit 110 is greater than or equal to the number of orders in the recheck work list. If the result of the determination is yes, a shelf unit 110 is selected. The controller 200 matches each of the multiple orders in the recheck work list with a storage location S in the selected shelf unit 110. The scanning device 300 scans the storage location identifier 112 corresponding to the storage location S of the selected shelf unit 110 to obtain storage location identification information. The controller 200 matches each of the multiple orders in the recheck work list with the storage location S according to the storage location identifier information. For example, in this step, the recheck operator P1 may scan the shelf identifier of an idle shelf unit 110 through the scanning device 300 to obtain the shelf barcode number and check the required quantity t of shelf units 110 according to the quantity n of the orders and the quantity m of storage locations in the shelf unit 110. For example, if the recheck work list includes n=40 orders and the shelf units 110 corresponding to all the shelf barcode numbers include m=12 storage locations S, the required quantity of shelf units is t=4.

[0120] Step S530: The scanning device 300 scans the identifier of the product to be rechecked to obtain product identification information. The recheck operator P1 scans the product barcode by using the corresponding scanning device 300. The number of recheck operators P1 and the corresponding scanning devices 300 may be the same as or less than the number of interaction units of the information interaction device. For example, in the embodiment shown in FIGS. 1 to 13, each information interaction device includes two interaction units, and selects a one-person operation mode or a two-person operation mode for rechecking according to the upstream and downstream operation efficiencies of the operation location. The one-person operation mode and the two-person operation mode can be flexibly selected to meet different operation efficiencies. When the overall workload is relatively low, the one-person operation mode is adopted to reduce labor costs. When the overall workload is relatively heavy, the two-person operation mode is adopted to match production.

[0121] Step S540: The controller 200 controls the information prompt unit of the information interaction device 113 corresponding to the storage location S where the item to be rechecked matches the listed order according to the item identification information to send prompt information. In the single-person operation mode, after one recheck operator P1 scans the item barcode corresponding to the item, the information prompt unit of the information interaction device at the storage location S corresponding to the shelf unit 110 sends prompt information, for example, turns on a first button light. In the two-person operation mode, after another recheck operator P1 simultaneously scans the item barcode corresponding to another item listed on the recheck work list, the information prompt unit at the storage location S corresponding to the shelf unit 110 sends prompt information, for example, turns on a second button light. After the recheck operator P1 scans the item, the system identifies the information of the order and storage location S corresponding to the item, and the corresponding button light of the information prompt unit is turned on. In the single-person operation mode, the button light corresponding to the scanning device 300 for scanning the item is turned on. In the two-person operation mode, the button lights of the information prompt section corresponding to the scanning device held by each recheck operator P1 are turned on, and the buttons of the two information prompt sections may have different colors. For example, the first button light indicates white and the second button light indicates green, or other colors may be assigned. The button lights are turned on to indicate the storage location S and the quantity of the product corresponding to the storage location S.

[0122] Step S550: Place the goods to be rechecked at the corresponding storage location S through the information interaction device 113 to send prompt information. After the information prompt unit indicates the storage location and the quantity of the goods in the storage location S corresponding to the scanned goods barcode, the recheck operator P1 places the goods in the corresponding storage location S.

[0123] After the product to be rechecked is placed in the storage location S corresponding to the information interaction device that sends the prompt information, verification information is sent to the controller 200 to verify that the product to be rechecked is placed in the storage location S from which the prompt information is sent. For example, in the one-person operation mode, one recheck operator P1 can press a first button light corresponding to the information prompt unit to confirm that the product has been placed in the appropriate recheck storage location S, and then recheck the next product. In the two-person operation mode, two recheck operators P1 can selectively press button lights on the information prompt units to confirm that the corresponding product has been placed in the appropriate storage location S, and then recheck the next product.

[0124] The above operations are repeated until all items listed on the recheck work list have been rechecked.

[0125] Step S560: After the products to be rechecked that are listed on the recheck work list have been rechecked, the shelf unit 110 loaded with the products to be rechecked is transferred to the packing section.

[0126] As shown in FIG. 18, step S560 includes a step of determining whether the packing and delivery of the orders corresponding to storage locations S of the corresponding number of shelf units 110 facing the packing section of the order re-check system has been completed.

[0127] The recheck section operated by recheck operator P1 and the packing section operated by packing operator P2 each have x shelf units 110, and the number of shelf units 110 required by the recheck work list is t (t≦x). After the recheck work list is completed, it is determined whether packing release corresponding to the first t shelf units 110 in the packing section closest to the recheck section in the rotational direction has been completed. Packing release refers to whether the order has been scanned in the packing section, and if scanning of the order has been completed in the packing section, packing release of the items listed in the order is considered to be completed.

[0128] When the packing and delivery of the orders corresponding to the storage locations S in the corresponding number of shelf units 110 is completed, the order recheck system automatically rotates the corresponding number of shelf units 110.

[0129] If all of the packing and delivery of orders corresponding to storage location S in the corresponding number of shelf units 110 has not been completed, it is determined whether the packing and delivery corresponding to the shelf unit 110 closest to the recheck section in the rotation direction has been completed. If the packing and delivery corresponding to the shelf unit 110 has been completed, the shelf shift device 120 of the order recheck system drives the shelf unit 110 to automatically rotate along the rail 122. If the packing and delivery corresponding to the shelf unit 110 has not been completed, the packing operator P2 quickly completes the packing and delivery of all of the orders corresponding to storage location S of the shelf unit 110, and the shelf shift device 120 of the order recheck system drives the shelf unit 110 to automatically rotate to a specified position along the rail 122 to provide an operable shelf unit 110 for the recheck operator P1. The above-described operations are repeated to complete the packing and delivery of all orders corresponding to all shelves participating in the recheck.

[0130] When the shelf unit 110 rotates automatically, the encoder of the drive motor determines whether the shelf unit 110 rotates in place, which includes the following: the encoder of the drive motor detects whether the shelf unit 110 rotates in place; if the shelf unit does not rotate in place, the drive motor is adjusted to a specified position through the controller; if the shelf unit rotates in place, the next operation can be performed.

[0131] Obtaining worklist information from the new recheck worklist is performed based on the operations described above.

[0132] It is determined whether the quantity of storage locations in the idle shelving units 110 in the recheck section is greater than or equal to the quantity of orders in the recheck work list, and the quantity of orders in the recheck work list is compared to the quantity of storage locations in the idle shelving units 110 in the recheck section. If the quantity of idle recheck storage locations is greater than or equal to the quantity of orders in the recheck work list, the aforementioned recheck step is performed before all operations are completed. If the quantity of idle recheck storage locations is less than the quantity of orders in the recheck work list, the packaging and delivery of the orders corresponding to the shelving unit 110 is completed, and the shelving unit 110 is automatically rotated. The aforementioned recheck is performed until the quantity of storage locations in the idle shelving units 110 is greater than or equal to the quantity of orders in the recheck work list.

[0133] The rechecking is repeated until the entire recheck worklist has been rechecked.

[0134] The order check method according to the embodiment of the present disclosure has the advantages of the order recheck device and order recheck system described above.
