For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily limit to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these process, method, product, or device.

[0041] With the rise and increasing development of e-commerce and online shopping, it has brought great development opportunities to the intelligentization of goods warehousing logistics. In the outbound process of the bin, after confirming the bin information, the control robot transports the bin from the warehouse to the slot of the buffer shelf, and at the same time lights up the electronic tag indicator light of the slot, and timely updates the usage information of the slot in the buffer shelf. During the process of the operator transporting the bin out of the warehouse, it is necessary to turn off the electronic tag indicator light of the idle slot. After confirming that the electronic tag indicator light of the slot is turned off, timely update the usage information of the slot in the buffer shelf to release the idle slot resources in the buffer shelf. However, when there are many outbound tasks of the bin, the operator needs to frequently turn off the electronic tag indicator light, which is prone to the situation of forgetting to turn off the light or turning off the wrong light, resulting in inaccurate usage of the stored slots and affecting the outbound efficiency of the intelligent warehousing system.

[0042] Regarding the above technical problems, a method for confirming shelf slot information provided by the present application installs slot detection devices in each slot of the shelf, and determines the usage status information of the slot according to the slot occupancy detected by the slot detection device, achieving the purpose of automatically identifying the usage status of the shelf slot and improving the outbound efficiency of the intelligent warehousing system.

[0043] Figure 1 FIG. 5 is a schematic structural diagram of a bin outbound system shown according to the first embodiment of the present application. The present application includes a plurality of shelves 101 for placing bins and a server 102 for managing the slot occupancy information on the shelves. The shelf 101 provided by the embodiment of the present disclosure includes multiple layers of bins, and each layer includes a plurality of slots 103. Each slot 103 is used to store the bins to be outbound transported by the handling robot. Among them, each slot includes a left support frame of the slot, a right support frame of the slot, a top support frame of the slot, and a bottom support frame of the slot.

[0044] Exemplarily, the bin outbound system further includes a handling robot 104 for transporting the bins to be outbound. Specifically, the handling robot 104 transports the bins to be outbound to the allocated slot 103 in response to the scheduling instruction sent by the server 102.

[0045] Figure 2 FIG. 6 is a schematic flowchart of a method for confirming shelf slot information shown according to the second embodiment of the present application. The execution subject of this embodiment can be the server in the bin outbound system, and no special limitation is made here. As Figure 2 shown, the method includes:

[0046] Step S21, obtaining the slot usage status information collected by the slot detection device.

[0047] On the basis of the slot structure shown in Figure 2 , a slot detection device is installed in each slot. Figure 3 FIG. 7 is a schematic structural diagram of the slot detection device shown according to the third embodiment of the present application. As Figure 3 shown, the slot detection device includes a transmitter 301, a receiver 302, and a detection circuit 303. Among them, the transmitter 301 and the receiver 302 are oppositely arranged in the slot, and the slot space between the transmitter 301 and the receiver 302 is used to accommodate the bins to be outbound. The transmitter 301 emits a detection signal in the direction of the receiver 302, the receiver 302 receives the detection signal, and the detection circuit 303 is connected to the receiver 302 to determine the usage status information of the slot according to whether the receiver 302 receives the detection signal.

[0048] Exemplarily, the transmitter 301 is installed at the middle of the bottom of the left support frame 304 of the slot. Correspondingly, the receiver 301 is installed at the middle of the bottom of the right support frame 305 of the slot. The detection circuit of the slot detection device is installed on the top support frame of the slot. Optionally, the transmitter 301 can also be installed at the middle of the bottom of the right support frame 305 of the slot. Correspondingly, the receiver 301 is installed at the middle of the bottom of the left support frame 304 of the slot.

[0049] Exemplarily, the transmitter 301 and the receiver 302 of the slot detection device are respectively the transmitter and the receiver of an opposed photoelectric sensor. Specifically, the semiconductor light source in the transmitter emits a detection signal, i.e., a light beam. The optical element of the receiver detects the light beam corresponding to the received detection signal, and the detection circuit outputs the usage status information of the slot. Exemplarily, when a bin is placed in the slot, the light beam is blocked by the bin, and the optical element of the receiver detects that the detection signal corresponding to the light beam is not received. At this time, the detection circuit outputs the usage status of the slot as the in-use status. Correspondingly, when the slot is vacant, the optical element of the receiver can detect the detection signal corresponding to the light beam. At this time, the detection circuit outputs the usage status of the slot as the idle status.

[0050] Step S22: Determine the slot usage information table in the system according to the slot usage status information, where the slot usage information table includes the location information of all slots and the corresponding usage information.

[0051] It should be noted that the slot usage information table is pre-set in the server and is an information table used to record the usage status of the slots on the shelf.

[0052] In this embodiment, the location information of each slot on the shelf is stored in the slot usage information table. Specifically, the location information of the slot is the shelf identification number, the slot row number, and the slot column number.

[0053] Exemplarily, after determining the slot usage status according to the information sent by the slot detection device, determine the location information of the corresponding slot according to the location of the slot detection device installed on the shelf, and update the slot usage status corresponding to the slot location information in the slot usage information table.

[0054] In summary, the shelf slot information confirmation method provided by the embodiment of the present invention installs a slot detection device for detecting the slot usage status in the slots of the shelf, so as to realize the automatic management of the usage status of the slots on the goods outbound shelf, improve the accuracy of managing the usage status of the shelf slots, and improve the outbound process of the intelligent warehousing system, thereby improving the outbound efficiency of goods.

[0055] Figure 4 This is a schematic flowchart of the shelf slot information confirmation method shown in the fourth embodiment of the present application. In Figure 2After determining the slot usage information table in the system according to the slot usage status information in S22 of the embodiment, as Figure 4 shown, this embodiment provides a process for the return of the to-be-stocked bins after the tallying is completed, which specifically includes the following steps:

[0056] Step S41: In response to the received outbound order, determine the information of the to-be-outbound bin corresponding to the goods to be outbound in the outbound order, where the information of the to-be-outbound bin includes the identifier of the to-be-outbound bin and the location information of the to-be-outbound bin.

[0057] In this embodiment, the information of the to-be-outbound bin hit by the order is determined according to the information of the goods to be outbound in the outbound order. Specifically, the information of the to-be-outbound bin includes the identifier of the to-be-outbound bin and the location information of the to-be-outbound bin. Exemplarily, the identifier of the to-be-outbound bin is the unique identifier of the bin. The location information of the to-be-outbound bin is the location information where the bin is stored on the shelf.

[0058] Step S42: Determine the location information of the to-be-used slot corresponding to the to-be-outbound bin according to the slot usage information table.

[0059] In this embodiment, after receiving the outbound task of the goods, an to-be-used slot is allocated for the to-be-outbound bin according to the stored slot usage information table. Specifically, all slots with an idle usage status are determined according to the slot usage information table, and the slot closest to the location of the to-be-outbound bin is determined as the to-be-used slot corresponding to the bin.

[0060] Step S43: Generate a handling instruction according to the determined location information of the to-be-used slot corresponding to the to-be-outbound bin and the location information of the to-be-outbound bin, and send the handling instruction to the handling robot, so that the handling robot transports the to-be-outbound bin to the to-be-used slot in response to the handling instruction.

[0061] In this embodiment, the bin outbound system also includes multiple handling robots for handling bins, and each handling robot is used to transport the bin to the corresponding slot. Specifically, a handling instruction is generated according to the determined location information of the to-be-used slot corresponding to the to-be-outbound bin and the location information of the to-be-outbound bin, where the handling instruction includes the bin picking action parameters, the handling distance, and the bin placing action parameters of the handling robot.

[0062] In this embodiment, after generating the handling instruction corresponding to the to-be-outbound bin, the server sends the handling instruction to the handling robot through the wireless network, so that the handling robot transports the to-be-outbound bin to the to-be-used slot in response to the handling instruction.

[0063] In summary, during the process of executing the goods outbound task according to the outbound order, the buffer slots are allocated to the outbound bins according to the slot usage information table, and the handling instructions for the handling robot are generated, so that the handling robot completes the outbound process of the outbound bins. By using the usage information of the slots recorded in the slot usage information table to manage the outbound process of the bins, the outbound efficiency of the intelligent warehousing system is improved.

[0064] In a possible implementation, after Figure 2 determining the slot usage information table in the system according to the slot usage status information in S22 of the embodiment, the shelf slot information confirmation method provided by the embodiment of the present invention may further include the following steps:

[0065] Determine the usage information table of the outbound bin according to the identification of the outbound bin and the position information of the corresponding slot to be used; if it is determined according to the slot usage status information collected by the slot detection device that the slot is in a used state, and it is determined according to the usage information table that there is no corresponding outbound bin in the slot, generate slot exception information; or, if it is determined according to the slot usage status information collected by the slot detection device that the slot is in an idle state, and it is determined according to the usage information table that there is an outbound bin stored in the slot, generate slot exception information.

[0066] In this embodiment, when sundries are placed in the slot or the slot detection device fails, the slot usage status information is inconsistent with the actual occupancy status. Exemplarily, when it is determined according to the slot usage status information collected by the slot detection device that the slot is in a used state, but it is determined according to the usage information table that there is no corresponding outbound bin in the slot, it can be determined that there is a problem with the detection of the slot detection device; or, when it is determined according to the slot usage status information collected by the slot detection device that the slot is in an idle state, but it is determined according to the usage information table that there is an outbound bin stored in the slot. The above states will cause the usage information table of the slot to be inconsistent with the actual slot occupancy situation, and it is necessary to confirm the occupancy status of the slot in time. Exemplarily, generate slot exception information and send the slot exception information to the management terminal to prompt the warehouse management personnel to confirm the usage of the slot in time and update the slot usage table according to the confirmed usage information in time.

[0067] In summary, when there are few empty bins, the consolidation of the sorting bins can be carried out in time. By increasing the turnover speed of the empty bins, the delay in outbound due to few idle bins can be avoided, so as to improve the outbound efficiency.

[0068] In a possible implementation, each slot further includes an indicator light, and the indicator light is installed on the top support frame of the slot for indicating the usage status of the slot. Whether there is a slot exception can be determined according to the status of the indicator light.

[0069] In this embodiment, the indicator lights installed in each slot are related to the usage status of the slot. The indicator lights of the slots are turned on or off according to the control instructions sent by the server. When a bin to be shipped out is stored in a slot, the slot is in an open state.

[0070] Exemplarily, when the slot status management is abnormal, for example, when other sundries are placed, causing the slot detection device to detect that the usage status of the slot has changed to an occupied state, the server will control the indicator light of the slot to be in an open state. At this time, if the staff member finds that the indicator light of the slot is on, but there is no bin stored in the slot, it can be confirmed that there is an abnormality in the current slot usage information management, so as to revise the usage status of the slot in time.

[0071] Exemplarily, the shelf further includes an alarm device, which is installed on the shelf and is used to prompt whether the usage status of the slot is consistent with the indication status of the indicator light. Specifically, the alarm device is a buzzer alarm. In this embodiment, when it is determined that there is an abnormal slot according to the status of the indicator light, a buzzer prompt sound will be emitted to prompt the staff to compare the usage situation of all slots and the on situation of the indicator lights in time, so as to timely discover the problem of abnormal slot usage information.

[0072] In summary, by using the slot usage status information collected by the slot detection device and the usage information table to determine the abnormal status of the slot, and timely confirming the usage status information of the abnormal slot, the accuracy of managing the shelf slot information is improved.

[0082] In some possible embodiments, the generation module is further configured to:

[0083] Determine the usage information table of the to-be-outbound bin according to the identifier of the to-be-outbound bin and the position information of the corresponding to-be-used slot;
