In another specific implementation provided by the present application, the control server is further configured to determine a fourth transporting apparatus, and send a fourth transporting instruction to the fourth transporting apparatus;

In this embodiment, the fourth transporting device specifically refers to a transporting device that needs to transport an order container that completes an order picking task from the first workstation, the control server determines the fourth transporting device and sends a fourth transporting instruction to the fourth transporting device, and the fourth transporting device transports the order container that completes the order picking task to a packing platform, an order combining platform, or other designated location according to the fourth transporting instruction.

In practical application, the goods buffer zone can be arranged in the container handling equipment or in the workstation, the goods buffer zone arranged in the workstation can be a buffer storage rack, correspondingly, the buffer storage rack can be provided with one buffer storage container or a plurality of buffer storage containers along the longitudinal direction of the laminate, the buffer storage rack can be further provided with a plurality of layers along the height direction, and each layer can be provided with the buffer storage containers. Based on the above, the control server is further configured to determine the position information of the first cargo in the cargo cache area of the first workstation according to a preset condition;

Namely, the control server determines the position information to be placed in the cargo cache region after the first cargo is transported to the first workstation according to preset conditions, and then puts the first cargo on the cargo cache region of the first workstation according to the position information.

It should be noted that in the present application, the heat of the first cargo, i.e. the shipment amount or the shipment frequency of the first cargo, the higher the heat of the cargo, the larger the shipment amount or the higher the shipment frequency of the cargo. The relevance between the goods refers to the frequency of selecting the goods together in the order task, such as nail polish and nail polish remover, which usually appear in one order, so that the relevance between the two goods is higher, and the two goods with higher relevance are placed in adjacent containers, so that the picking efficiency can be effectively improved. The order sequence to be processed specifically refers to the order sequence sent to the first workstation, if the order sequence of the first goods order is closer, the first goods are placed at a position which is convenient to pick, and if the order sequence of the first goods order is closer, the first goods can be placed at a position at the edge of the goods cache area.

In another embodiment provided by the present application, since the number of orders that can be carried by each workstation is constant, if all pending orders that hit the first item are sent to the first workstation, the load handling capacity of the first workstation is also taken into account.

Based on this, the control server is further configured to detect an order quantity of a first to-be-processed order in the first workstation, determine a second workstation and a second handling device when the order quantity is greater than a preset threshold value, send a second to-be-processed order which hits the first cargo in the to-be-processed order set to the second workstation, and send a second handling instruction to the second handling device, wherein a distance between the second workstation and the first workstation is less than a preset distance threshold value;

the second carrying equipment is configured to respond to the second carrying instruction, take out the first goods with the quantity corresponding to the second order to be processed from the goods buffer area of the first workstation and place the first goods in the goods buffer area of the second workstation;

The control server is used for monitoring the order quantity of the to-be-processed orders in the first workstation in real time when the to-be-processed orders are distributed, and if the order quantity of the first workstation is larger than a preset threshold value, it is indicated that the to-be-processed orders of the first workstation are saturated.

The distance between the second workstation hit by the control server and the first workstation is smaller than a preset distance threshold value, for example, the second workstation is adjacent to the first workstation, and therefore the second workstation can conveniently obtain the first goods which are put on the shelf and reach the goods cache area in the first workstation from the first workstation. And the second carrying equipment responds to the second carrying instruction, moves to the goods buffer area of the first workstation to take out the first goods with the quantity corresponding to the second order to be processed, moves to the goods buffer area of the second workstation, and puts the first goods on shelf to the goods buffer area of the second workstation, so that the first goods can be conveniently picked from the goods buffer area of the second workstation in the second workstation according to the second order to be processed.

The above embodiment is applicable to a situation where the first cargo has been transported to the cargo buffer of the first workstation, and in this situation, the first workstation cannot process the order due to order busting, so it needs to determine the second workstation to assist order picking. In order to further improve the picking efficiency of the goods, the pending orders hitting the first goods may be directly split when the pending orders are allocated, for example, the number of the first goods hitting in the pending order set is large and obviously exceeds the load of one workstation, and at this time, the control server may determine a plurality of workstations to pick the goods directly according to the number of the first goods.

Based on this, the control server is further configured to determine a third workstation picking the first goods and a fifth transporting device transporting the first goods according to the number of the first goods hit by the to-be-processed order set, send a fifth transporting instruction to the fifth transporting device, and send a fourth to-be-processed order hit by the first goods in the to-be-processed order set to the third workstation, wherein the distance between the third workstation and the first workstation is smaller than a preset distance threshold;

In this scenario, when the control server allocates the to-be-processed orders, the control server determines, according to the quantity of the first goods, a third workstation and a fifth transporting device for transporting the first goods, and sends a fourth to-be-processed order, which hits the first goods in the to-be-processed orders, to the third workstation. The control server determines that the workstations used for picking the first goods are a first workstation and a third workstation according to the quantity of the hit first goods, determines that the first carrying equipment carries the first goods to a goods cache region of the first workstation, carries the first goods to a goods cache region of the third workstation through the fifth carrying equipment, sends a first to-be-processed order hitting the first goods in the to-be-processed order set to the first workstation, and sends a fourth to-be-processed order hitting the first goods to the third workstation, so that the first goods are picked in the first workstation and the third workstation at the same time. It should be noted that in practical applications, the number of the third stations may be determined according to practical situations, for example, one or more third stations may be determined.

The fifth transporting device transports the first cargo from the cargo inventory position of the first cargo to the third workstation in response to the fifth transporting instruction, and puts the first cargo on the shelf in the cargo cache area of the third workstation, where the cargo inventory position of the first cargo is determined as in the above embodiment, which is not described herein again.

And in the third workstation, taking out the first goods from the goods buffer area of the third workstation according to the fourth order to be processed, placing the first goods in a corresponding container, and finishing the picking of the first goods.

In the above embodiment, for the description of different scenes in the cargo cache area from the first cargo to the workstation, in the picking process of the first cargo, the control server may also monitor the stock condition of the cargo in each workstation in real time, and perform corresponding adjustment according to the stock condition.

Based on this, the control server is further configured to, in a case that it is detected that the number of the first goods in the goods cache area of the first workstation is smaller than a cache threshold value, determine a goods inventory position of the second goods according to the number of the second goods hit in the set of orders to be processed, determine a third transporting device for transporting the second goods, send a third transporting instruction to the third transporting device, and send a third order to be processed, which hits in the second goods, in the set of orders to be processed to the first workstation;

the first workstation is further configured to rack the second item to an idle buffer container in a goods buffer of the first workstation and pick the second item according to the third pending order.

In this scenario, a first item performs a picking operation in the first workstation, and as time goes by, when the control server detects that the number of the first item in the item buffer of the first workstation is smaller than the buffer threshold, and an order hitting the first item in the pending order set is also smaller than the threshold, the item inventory location of the second item may be determined according to the number of the second item hit by the pending order set. That is, when the first goods are selected soon and no or a small number of the subsequently newly added orders to be processed hit the first goods, the second goods with a higher hit rate of the next order to be processed can be determined, and the second goods are placed in the first workstation for selection.

Therefore, after determining the goods inventory location of the second goods, the control server needs to determine a third transporting device for transporting the second goods, send a third transporting instruction to the third transporting device, and send a third pending order which hits the second goods in the pending order set to the first workstation. It should be noted that the type of the third transporting device is related to the cargo stocking position of the second cargo and the carrier for loading the cargo, and the specific selection of the third transporting device is described above in relation to the first transporting device and will not be described herein again.

And the third carrying equipment moves to the goods stock position of the second goods according to the third carrying instruction, the second goods are carried to the first workstation, the second goods are put on the shelf to the goods buffer area of the first workstation, and the first workstation can pick the second goods according to the third to-be-processed order.

In the above, the number of the first goods in the first workstation is smaller than the cache threshold, and the order hitting the first goods in the to-be-processed order set is also smaller than the threshold, but in practical application, unprocessed orders are increased at any time, that is, as time goes on, a new to-be-processed order set is generated, the new to-be-processed order set is a to-be-processed order that arrives after the to-be-processed order set, and if the first goods hit by the new to-be-processed order set, a replenishment operation needs to be performed on the first goods.

Based on this, the control server is further configured to determine a first to-be-replenished goods according to the number of the first to-be-replenished goods hit in the newly-added order set, determine sixth carrying equipment for carrying the first to-be-replenished goods, send a sixth carrying instruction to the sixth carrying equipment, and send a fifth to-be-processed order hit in the newly-added order set to the first to-be-replenished goods to the first workstation, when it is detected that the number of the first to-be-replenished goods in the goods buffer area of the first workstation is smaller than a buffer threshold;

the sixth transporting device is configured to transport the first goods to be restocked to the first workstation in response to the sixth transporting instruction moving to the goods inventory position;

In this scenario, the control server determines that a large number of orders hit the first goods in the following sequence according to the number of the first goods hit by the newly added to-be-processed order set although it is detected that the number of the first goods in the goods cache region of the first workstation is smaller than the cache threshold value, and determines that the first goods to be replenished are required to be transported to the first workstation from the goods inventory position when the number of the first goods in the goods cache region of the first workstation is insufficient. Therefore, a sixth transporting device for transporting the first goods to be replenished is determined, a sixth transporting instruction is issued, and meanwhile, a fifth order to be processed, which hits the first goods to be replenished in the newly-added order set to be processed, needs to be sent to the first workstation.

The sixth transporting device, in response to the sixth transporting instruction, transports the first goods to be restocked to the first workstation from the goods inventory position of the first goods to be restocked, and puts the first goods to be restocked on the shelf in the goods buffer area of the first workstation, where the goods inventory position of the first goods is determined as in the above embodiment, which is not described herein again. In the first work station, the picking of the first goods is continued.

Through the warehouse management system that this application provided, set up the goods buffer at the workstation, deposit the goods that pending order hit, avoided frequently carrying the goods from between goods stock position and the workstation, improved and selected efficiency.

Secondly, the stock position of the goods is determined according to the quantity of the goods hit by the to-be-processed order set, so that the goods can be conveniently conveyed to the workstations as much as possible, the goods are collectively put on one workstation, the orders hit by the goods are sent to the workstation, the to-be-processed orders hit by the goods are collectively processed by the workstation, and the order picking efficiency is effectively improved.

Here, if the order to be processed of the workstation explodes, other workstations can be found around the workstation to pick the goods in a matching manner, the source of the goods can be a goods buffer area of a previous workstation or a goods inventory position of the goods, and when the previous workstation does not process the goods, a plurality of workstations can be selected to cooperatively process the goods in parallel, so that the order picking efficiency is further improved.

And finally, whether goods need to be supplemented or not can be determined according to the newly added order set to be processed, if the goods are hit by the newly added order set to be processed, the operation of supplementing the goods needs to be executed, and if the new goods are clearly found by the newly added order set to be processed, the new goods can be put on the shelf to a goods cache region of the workstation, so that the sorting efficiency of the order set to be processed is improved.
