The application directions of artificial intelligence in logistics can be roughly divided into two types: 1) those empowered by AI technology such as unmanned trucks, AGVs, AMRs, forklifts, shuttles, stackers, unmanned distribution vehicles, drones, Intelligent devices such as service robots, robotic arms, and smart terminals replace part of the labor force; 2) Software driven by technologies or algorithms such as computer vision, machine learning, and operations optimization, such as transportation equipment management systems, warehouse management, equipment scheduling systems, order distribution systems, etc. The system improves labor efficiency. With the research and progress of smart logistics, this technology has been applied in many fields, such as retail and e-commerce, electronic products, tobacco, medicine, industrial manufacturing, shoes and clothing, textiles, food and other fields.

Please refer to FIG. 1 , which shows a schematic diagram of the implementation environment of a picking scheduling method provided by an embodiment of the present invention. As shown in Figure 1, the implementation environment includes: multiple feeding ports 101 and a storage system. The warehousing system includes a server 102 and a transport device 103. The number of transport devices 103 may be one or more, and they may be connected to the server 102 through a wired or wireless network to communicate with the server. It should be noted that Figure 1 takes three transport devices (103A-103C) and three feeding ports (101A-101C) as an example for illustration. The number of transport devices and feeding ports shown in Figure 1 does not limit the scope of the present invention. The number of transport devices and feeding ports that can be included in the implementation environment provided by the embodiment is limited.

Wherein, the server 102 can be used to control the transport device to transport the goods in the order to the feeding port 103 according to the status of the feeding port when receiving the outbound task of the order. Among them, the status of the feeding port may include a deliverable state, an undeliverable state, an idle state, and a busy state. The feeding port in idle state is also called the idle feeding port. The free feeding port refers to the feeding port that has no assigned orders. The feeding port in busy state is also called the busy feeding port. The busy feed port refers to the feed port that has been assigned an order. When the feeding port is in a deliverable state, the feeding port can receive delivered goods, and the feeding port can be an idle feeding port or a busy feeding port. When the feeding port is in a non-deliverable state, the feeding port cannot receive delivered goods. In practical applications, the feeding port in the deliverable state may be an open feeding port. A feeding port in an undeliverable state may be a feeding port that cannot receive goods due to closure or malfunction. For example, the server 101 may be a single server, a service cluster composed of multiple servers, or a cloud computing center.

The transport device 103 can be used to transport goods to the feeding port 103 according to the control of the server 102 . Among them, the transportation device can transport the goods from the picking station to the feeding port. By way of example, the transport device 103 may be a transport robot. For example, flip-type automatic guided vehicle (AutomatedGuidedVehicle, AGV), etc.

Optionally, the implementation environment may also include: a feeding port management device 104. The feeding port management device 104 is connected to the server 102 through a wired or wireless network. The feeding port management device 104 may be used to transmit the status of multiple feeding ports to the server 101 . For example, if the weight of the cargo container (such as a box) used to carry goods at the feeding port is greater than or equal to the set quantity or weight threshold, it can indicate that the goods container is full of goods and the feeding port needs to be closed to wait for staff to replace the goods container. . Then the feeding port management device can determine that the status of the feeding port is an undeliverable state. On the contrary, if the weight of the goods container is less than or equal to the set weight threshold, it indicates that the goods container is not full of goods, and there is no need to close the feeding port. Then the feeding port management device can determine that the state of the feeding port is a deliverable state. For example, it can also be determined based on the number of goods in the container at the feeding port to determine whether the container is full of goods, and then determine whether the feeding port needs to be closed. Of course, the feeding port management device can also determine different states of the feeding port under other circumstances. For example, if there is a fault at the feeding port, the feeding port management device can determine that the status of the feeding port is an undeliverable state by receiving a setting operation. The setting operation may be a writing operation by the staff regarding the undeliverable status of the feeding port, etc. It should be noted that the feeding port management device 104 may be a terminal such as a personal computer or a server.

Optionally, the implementation environment shown in FIG. 1 may also include an order management device 105. The order management device 105 may be connected to the server 101. Order management device 105 may be used to generate picking orders. Among them, the order can directly include the number of deliveries of the goods in the order. Alternatively, the order may include detailed information about the goods in the order (also known as input items, commodities or packages). The order management device 105 is used to determine the number of delivery times of the goods based on the detailed information of the goods. For example, the detailed information of the goods in the order may include the name, type, weight, etc. of the goods. The order management device 105 calculates the number of delivery times of the goods based on the weight of the goods and the carrying capacity of the transportation device. For example, if the weight of the goods in the order is 10 kilograms (kg), and the carrying capacity of the transport device is 5kg, the number of deliveries corresponding to the order is 2. Or, for example, the order management device 105 may use an upstream process algorithm to calculate the order. The order can include the name of the item and the number of times the item will be delivered.

Correspondingly optionally, the server 101 can also be used to control the transport device to transport the goods in the order to the feeding port according to the status of the feeding port and the number of deliveries of the goods in the order when receiving the outbound task of the order. In the embodiment of the present invention, the server 101 is used to implement any of the picking scheduling methods provided in the embodiment of the present invention.

For example, the implementation environment shown in Figure 1 can be the environment shown in the AGV warehouse where the AGV sorting system is located. The feeding port management device transmits status information of all feeding ports included in the AGV warehouse to the server. After receiving the outbound task of the order, the server can allocate a feeding port to the order based on the status of the feeding port transmitted by the feeding port management device and the number of delivery times of the goods in the order transmitted by the server. The staff moves the goods in the order from the picking site to the AGV. The server controls the AGV to transport the goods in the order to the feeding port assigned to the order.

Please refer to Figure 2, which shows a flow chart of a picking scheduling method provided by an embodiment of the present invention. This picking scheduling method can be applied to the implementation environment shown in Figure 1 and is executed by the server in the implementation environment. As shown in Figure 2, the picking scheduling method includes steps 201-203.

Step 201: After receiving the outbound task for the target order, allocate a delivery port for the target order, and control the transportation device to deliver the goods in the target order to the allocated material port.

In the embodiment of the present invention, the server can poll the status of all feeding ports in the implementation environment where the picking scheduling method is located every set period, and determine that they are in a deliverable state. When receiving the outbound task for the target order, allocate the delivery port to the target order from the delivery-ready state. The transport device can obtain information on its path to the allocated feeding port. Deliver the goods in the target order to the feeding port according to the path information.

Wherein, the feeding port in the deliverable state may include an idle feeding port in the deliverable state and a busy feeding port in the deliverable state. Optionally, when receiving an outbound task for the target order, the server can allocate a feeding port to the target order from the idle feeding ports in a deliverable state. In this way, allocating the idle feeding port of the unallocated order to the target order allows the transport device to deliver the goods to the allocated idle feeding port immediately after carrying the goods of the target order. Compared with assigning a busy feeding port with an order assigned to the target order, there is no need to wait for other transportation devices to deliver completed goods to the busy feeding port, which improves the work efficiency of the transportation device.

Step 202: Before the delivery of the goods in the target order is completed, if the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, other feeding ports in the deliverable state are reallocated to the target order.

In the embodiment of the present invention, before the delivery of the goods in the target order is completed, at least one of the following situations may occur: the goods in the target order are in the process of being manually transported to the transportation device, or the transportation device distributes the goods in the target order to During the transportation process of the feeding port, the transport device has transported the goods in the target order to the assigned feeding port but has not yet completed delivery to the feeding port.

The status of the feed slot assigned to the target order may change before the delivery of the items in the target order is completed. For example, before the delivery of the goods in the target order is completed, the goods container at the feeding port assigned to the target order is filled with goods. At this time, the worker can perform the operation of closing the feeding port, triggering the status of the feeding port to change from the deliverable state to Undeliverable status. Thus, the goods container filled with goods is taken away and replaced with a new goods container. If the server detects that the status of the feed port assigned to the target order changes from the deliverable state to the undeliverable state, the server can unbind the target order from the assigned feed port and allocate other feed ports in the deliverable state to the target order. The other feeding ports in the deliverable state may refer to the feeding ports in the deliverable state among the multiple feeding ports included in the implementation environment after the status of the feeding port allocated to the target order is changed from the deliverable state to the undeliverable state.

Step 203: Control the transportation device to deliver the goods in the target order to other feeding ports.

In this embodiment of the present invention, the server may control the transport device to obtain other delivery ports newly allocated for the target order that are in a deliverable state. So that the transport device can obtain the path information to the feeding port. Deliver the goods in the target order to the newly allocated feeding port according to the route information.

It should be noted that if the goods in the target order are delivered to the newly allocated feeding port, the status of the newly allocated feeding port is changed from the deliverable state to the undeliverable state. Then the server can reallocate other delivery ports to the target order again. Until the transportation device completes delivery of the goods in the target order.

As can be seen from the above embodiment, in this embodiment, when receiving an outbound task for a target order, a delivery port is assigned to the target order, and the transportation device is controlled to deliver the goods in the target order to the allocated Feeding port. Before the delivery of the goods in the target order is completed, if the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, other feeding ports in the deliverable state will be reallocated for the target order, and the transportation device will be controlled. The goods in the target order are delivered to other feeding ports. In this technical solution, before the delivery of the goods in the target order is completed, if the feeding port fails or the feeding port container is closed due to any situation such as being full, the status of the feeding port assigned to the target order will be changed from the deliverable state to the undeliverable state. status, you can allocate other feeding ports in the deliverable state to the target order, realizing flexible allocation between the target order and the feeding ports. This avoids the problem in the related technology that due to the fixed allocation of the target order and the feeding port, the transport device can only be in a waiting state when the state of the feeding port allocated to the target order is in an undeliverable state. It improves the working efficiency of the transportation device, shortens the sorting time of target orders, and improves picking efficiency.

For example, when there is a delivery port, if the cargo container of a delivery port is full and the state of the delivery port changes to an undeliverable state, the server can directly re-order the target order delivered to the delivery port. Assign other feeding ports to directly control the transport device to deliver the goods in the target order to the reassigned feeding ports. There is no need to wait for staff to change cargo containers, improving picking efficiency. Moreover, due to the replacement efficiency of the fully loaded cargo containers at the feeding port, the impact on the overall picking efficiency is reduced. Therefore, the requirement for the efficiency of manual replacement of cargo containers is reduced, and labor costs are reduced.

Another picking scheduling method provided by an embodiment of the present invention. This picking scheduling method can be applied to the implementation environment shown in Figure 1 and is executed by the server in the implementation environment. The picking scheduling method includes steps 301-303.

Step 301: After receiving the outbound task for the target order, allocate a delivery port for the target order, and control the transportation device to deliver the goods in the target order to the allocated material port.

In the embodiment of the present invention, the server can poll the status of all feeding ports in the implementation environment where the picking scheduling method is located every set period, and determine that they are in a deliverable state. When receiving the outbound task for the target order, allocate the delivery port to the target order from the delivery-ready state. The transport device can obtain information on its path to the allocated feeding port. Deliver the goods in the target order to the feeding port according to the path information.

Wherein, the feeding port in the deliverable state may include an idle feeding port in the deliverable state and a busy feeding port in the deliverable state. Optionally, when receiving an outbound task for the target order, the server can allocate an idle feeding slot to the target order from the idle feeding slots in a deliverable state. In this way, allocating the idle feeding port of the unallocated order to the target order allows the transport device to deliver the goods to the allocated idle feeding port immediately after carrying the goods of the target order. Compared with assigning a busy feeding port with an order assigned to the target order, there is no need to wait for other transportation devices to deliver completed goods to the busy feeding port, which improves the work efficiency of the transportation device.

Optionally, the feeding port management device can periodically transmit status information of each of all feeding ports to the server. This allows the server to determine the delivery port in the implementation environment after obtaining the status information of each feeding port. For example, the feeding port management device may periodically transmit the feeding port identification of each feeding port and the status information corresponding to the feeding port identification to the server. When the status information obtained by the server includes the deliverable state, the server can determine the feeding port identification corresponding to the status information, and the feeding port indicated by the feeding port identification is the feeding port in the deliverable state.

In the embodiment of the present invention, the server can receive the outbound task of the target order when the target order reaches the picking opportunity. The picking timing of the target order may be the moment when the goods in the target order arrive at the picking site. For example, after detecting that the goods in the target order arrive at the picking site, the staff can input the outbound task of the target order to the server, so that the server can receive the outbound task of the target order. Alternatively, after detecting that the goods in the target order arrive at the picking site, other devices such as the order management device send the outbound task of the target order to the server. Optionally, the outbound task can include the outbound priority of the target order. The outbound priority can be determined based on the required outbound time of the target order. Alternatively, the outbound task can also directly include the time required for the target order to be outbound.

In an optional implementation, the number of target orders received by the server for the outbound task can be one or more. When there are multiple target orders, the server can allocate delivery ports to multiple target orders at the same time. Alternatively, the server can allocate delivery ports to multiple target orders in sequence according to the set picking order. Optionally, the picking order may include: the order of delivery times of goods in multiple target orders from large to small, or the picking order may include the order of outbound priority from high to low.

Step 302: Before the delivery of the goods in the target order is completed, if the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, other feeding ports in the deliverable state will be reallocated to the target order.

In the embodiment of the present invention, before the delivery of the goods in the target order is completed, at least one of the following situations may occur: the goods in the target order are in the process of being manually transported to the transportation device, or the transportation device distributes the goods in the target order to During the transportation process of the feeding port, the transport device has transported the goods in the target order to the assigned feeding port but has not yet completed delivery to the feeding port.

The status of the feed slot assigned to the target order may change before the delivery of the items in the target order is completed. For example, before the delivery of the goods in the target order is completed, the goods container at the feeding port assigned to the target order is filled with goods. At this time, the worker can perform the operation of closing the feeding port, triggering the status of the feeding port to change from the deliverable state to Undeliverable status. Thus, the goods container filled with goods is taken away and replaced with a new goods container. If the server detects that the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, the server can reallocate other feeding ports in the deliverable state for the target order. The other feeding ports in the deliverable state may refer to the feeding ports in the deliverable state among the multiple feeding ports included in the implementation environment after the status of the feeding port allocated to the target order is changed from the deliverable state to the undeliverable state.

It should be noted that the implementation process of the server re-allocating other feeding ports in the deliverable state for the target order can refer to the implementation process of the server allocating the delivery port for the target order in step 302. In this embodiment of the present invention, No further details will be given.

Step 303: Control the transportation device to deliver the goods in the target order to other feeding ports.

In this embodiment of the present invention, the server may control the transport device to obtain other delivery ports newly allocated for the target order that are in a deliverable state. So that the transport device can obtain the path information to the feeding port. Deliver the goods in the target order to the newly allocated feeding port according to the route information.

Regarding the process of the server allocating a feeding port in a deliverable state to a target order, the embodiment of the present invention takes the server as an example of allocating a feeding port in a deliverable state to a target order. The server allocates a feeding port in a deliverable state to the target order. Give a schematic explanation.

The process of the server allocating a delivery port to the target order may include: the server allocates a delivery port to the target order based on the number of deliveries of the goods in the target order. The greater the number of deliveries of goods in the target order, the smaller the distance between the feeding port assigned to the target order and the picking station.

Among them, the server can pre-store the distances between all feeding ports and picking sites. After receiving the outbound task for the target order, the server can obtain all delivery ports, the distance between them and the picking site, and the number of times the goods in the target order have been delivered. Then, according to the number of deliveries of the goods in the target order, the delivery port is assigned to the target order.

In an optional implementation manner, the feeding port in the implementation environment to which the picking scheduling method provided by the embodiment of the present invention is applied can be divided into multiple different feeding port areas. That is, there may be multiple feeding port areas in the implementation environment, and there is at least one feeding port in each feeding port area. The multiple feeding port areas are divided into multiple feeding ports in order from nearest to far according to the distance between the feeding port and the picking station. The multiple feeding ports refer to the feeding ports that exist in the implementation environment. Orders can be divided according to the number of times the goods in the order are delivered, and have multiple ranges. Among them, the corresponding relationship between the feeding port area and the frequency range can be one-to-one, one-to-many or many-to-one. That is to say, multiple feeding port areas can correspond to multiple frequency ranges one by one. Multiple feeding port areas can correspond to a range of times. Or, a feeding port area can correspond to multiple ranges of times.

For example, it is assumed that the feeding port area corresponds to the frequency range. There may be a first feeding port area, a second feeding port area, and a third feeding port area in the implementation environment. Among them, the distance between the first feeding port area and the picking station ranges from 0 to A meters. The distance between the second feeding port area and the picking station ranges from A to B meters. The distance between the third feeding port area and the picking station ranges from B to C meters. Among them, A is less than B, and B is less than C. The first feeding port area corresponds to the first number range, that is, if the delivery times of the goods in the order fall within the first number range, the server can control the transportation device to feed the goods in the order to the first feeding port area. Oral delivery. The second feeding port area corresponds to the second frequency range, that is, if the delivery times of the goods in the order fall within the second frequency range, the server can control the transportation device to deliver the goods in the order to the feeding port in the second feeding port area. . The third feeding port area corresponds to the third frequency range, that is, if the delivery times of the goods in the order fall within the third frequency range, the server can control the transportation device to deliver the goods in the order to the feeding port in the third feeding port area. .

Based on this, as shown in Figure 3, the process of the server allocating a delivery port to the target order based on the number of deliveries of the goods in the target order may include:

Step 401: Determine the target feeding port area corresponding to the frequency range among the multiple feeding port areas according to the frequency range to which the number of delivery times of the goods in the target order belongs.

Optionally, the server may store a corresponding relationship between the number range and the area identifier of the feeding port area. Then the server queries the corresponding relationship to obtain the corresponding target area identifier based on the range of times to which the delivery times of the goods in the target order belong. The feeding port area indicated by the target area identification is used as the target feeding port area.

Step 402: Determine whether there is a delivery port in the target feeding port area. If yes, perform step 403; if not, perform step 404.

In the embodiment of the present invention, after the server determines the target feeding port area for the target order, the server can obtain the status information of all the feeding ports in the target feeding port area. The status information of all the feeding openings is traversed to determine whether there is a feeding opening in a deliverable state in the target feeding opening area based on the status information of all the feeding openings.

Step 403: Select a delivery port from the target feeding port area and assign it to the target order.

In the embodiment of the present invention, if there is a delivery port in the target feeding port area, it indicates that the target order can be delivered to the feeding port in the target feeding port area by the transportation device. Then the server can select a delivery port from the target feeding port area and assign it to the target order, so as to allocate the delivery port selected from the target feeding port area to the target order.

Optionally, when there is a delivery port in the target feeding port area, the server can arbitrarily select a delivery port from all the delivering ports in the target feeding port area and assign it to target order. Alternatively, the server selects a delivery port from the target feeding port area that is in a deliverable state and is closest to the picking site and assigns it to the target order. In this way, since the target order can be assigned the feeding port closest to the picking site, the delivery speed of the target order is guaranteed and the delivery efficiency is improved.

Step 404: Select a feeding port area as a new target feeding port area, and allocate the delivery port in the new target feeding port area to the target order.

In the embodiment of the present invention, when there is no delivery port in the target feeding port area, the server can enter the waiting allocation state for the target order. The server in the waiting for allocation state can periodically obtain the status information of each feeding port in the target feeding port area transmitted by the feeding port management device. If there is a delivery port in the target feeding port area, select the delivery port from the target feeding port area and assign it to the target order.

Alternatively, when the server does not have a delivery port in the target feeding port area, it can select a feeding port area as a new target feeding port area, and there is a delivery port in the new target feeding port area. In the case of , select the delivery port from the new target material port area and assign it to the target order. Of course, if there is no delivery port in the new target feeding port area, then continue to select a feeding port area from all the feeding port areas except the new target feeding port area as another new target feeding port area. . Until a delivery port can be selected and assigned to the target order.

Optionally, the process of the server selecting a feeding port area as a new target feeding port area may include multiple implementation methods. The embodiments of this application take the following five as examples for explanation.

The first optional implementation method is that the server can select another feeding port area corresponding to the range of delivery times of the target order from multiple feeding port areas as the new target feeding port area. The other feeding port area may be any feeding port area other than the target feeding port area among the multiple feeding port areas corresponding to the frequency range to which the target order's delivery times belong.

The second optional implementation method is that the server can select the feeding port area adjacent to the target feeding port area as the new target feeding port area in order of distance from the picking site to the farthest. That is to say, the new target feeding port area is the next feeding port area adjacent to the target feeding port area selected in order of distance from the feeding port area to the picking station.

For example, when the server determines that there is no delivery port in the target feeding port area, it can obtain the distance range between each feeding port area and the picking site in all the feeding port areas. The median value of the target distance range corresponding to the target feeding port area is sequentially compared with the median value of the distance range corresponding to other feeding port areas in all feeding port areas except the target feeding port area.

When the median value of any distance range in the distance range corresponding to other feeding port areas is greater than the median value of the target distance range, it indicates that the target feeding port area is not the feeding port area farthest from the picking site. Then, the server selects the next feeding port area adjacent to the target feeding port area as the new target feeding port area in order from nearest to farthest between the feeding port area and the picking site. Wherein, the next feeding port area adjacent to the target feeding port area refers to the next feeding port area adjacent to the target feeding port area. That is, the distance between the next feeding port area and the picking station is second only to the distance between the target feeding port area and the picking station.

When the median value of any distance range in the distance range corresponding to other feeding port areas is smaller than the median value of the target distance range, it indicates that the target feeding port area is the feeding port area farthest from the picking site. Then the server can use other implementation methods to select the new target feeding port area.

The third optional implementation method is that the server can select another feeding port area corresponding to the frequency range adjacent to the frequency range to which the target order's delivery times belong as the new target feeding port area.

Wherein, the frequency range adjacent to the frequency range to which the target order's delivery times belong may refer to the frequency range adjacent to the frequency range to which the target order's delivery times belong in descending order of order delivery times. Alternatively, the frequency range adjacent to the frequency range to which the target order's delivery times belong may refer to the frequency range adjacent to the frequency range to which the target order's delivery times belong in order from small to large order delivery times. For example, continue to use the above example as an example. Assume that the number of times the target order is delivered is in the second frequency range. Then, in order from small to large, the number of times the target order is delivered is adjacent to the number of times the target order is in the range. The range of times is the third range of times. In descending order of order delivery times, the frequency range adjacent to the frequency range to which the target order's delivery times belong is the first number range.

The fourth optional implementation method is that the server can select the feeding port area among multiple feeding port areas that is in a deliverable state and is closest to the picking site as the new target feeding area.

In the embodiment of the present invention, the server can obtain the status of each feeding port in each feeding port area, thereby determining the feeding port area in which a feeding port in a deliverable state exists. Select the feeding port area closest to the picking station from the feeding port area as the new target feeding area.

The fifth optional implementation method is that the server can select the feeding port area among multiple feeding port areas that is in a deliverable state and is closest to the target feeding port area as the new target feeding area.

In the embodiment of the present invention, the server can obtain the status of each feeding port in each feeding port area, thereby determining the feeding port area in which a feeding port in a deliverable state exists. Calculate the distance between each feeding port area in the feeding port area and the target feeding port area, and select the feeding port area closest to the target feeding port area from the feeding port area as the new target feeding area.

In the embodiment of the present invention, the multiple ranges of times of delivery of goods in the order can be fixed values. Alternatively, the frequency range can also be adjusted in a timely manner based on the number of deliveries of goods in the order within the actual batch range.

Optionally, the method also includes: the server can obtain the delivery times of the goods in all orders every set period. Divide multiple frequency ranges according to the value range of the delivery times of goods in all orders.

Optionally, the set period can be stored in the server, or the set period can be manually set on the server in advance. For example, the set period may be 1 day, 15 days, or 30 days. The server can obtain the delivery times of all goods in all orders every set period, and then divide the value range into the target number of times according to the value range of the delivery times of goods in all orders and the target quantity in the feeding port area. scope. Alternatively, the server can obtain the delivery times of goods in all orders every set period, and then divide the value range using a set ratio according to the value range of the delivery times of goods in all orders and the target quantity in the feeding port area. is the target number of times. Divide the target number into frequency ranges, in order from large to small delivery times, and the size of the frequency range decreases in sequence.

As can be seen from the above embodiment, in this embodiment, when receiving an outbound task for a target order, a delivery port is assigned to the target order, and the transportation device is controlled to deliver the goods in the target order to the allocated Feeding port. Before the delivery of the goods in the target order is completed, if the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, other feeding ports in the deliverable state will be reallocated for the target order, and the transportation device will be controlled. The goods in the target order are delivered to other feeding ports. In this technical solution, before the delivery of the goods in the target order is completed, if the feeding port fails or the feeding port container is closed due to any situation such as being full, the status of the feeding port assigned to the target order will be changed from the deliverable state to the undeliverable state. status, you can allocate other feeding ports in the deliverable state to the target order, realizing flexible allocation between the target order and the feeding ports. This avoids the problem in the related technology that due to the fixed allocation of the target order and the feeding port, the transport device can only be in a waiting state when the state of the feeding port allocated to the target order is in an undeliverable state. It improves the working efficiency of the transportation device, shortens the sorting time of target orders, and improves picking efficiency.

The status of each feeding port. According to the judgment of whether the status of each feeding port in other feeding port areas is in an undeliverable state, it is determined whether there is no feeding port in a deliverable state in other feeding port areas. When the status of each feeding port in other feeding port areas is in a non-deliverable state, it is determined that there is no feeding port in a deliverable state in other feeding port areas. When the status of any of the feeding openings in the other feeding opening areas is not undeliverable, it is determined that there is a feeding opening in the deliverable state in the other feeding opening areas.

Step 505: Stop allocating the delivery port for the target order.

When there is no delivery port in the target feeding port area, and there is no delivery port in the other feeding port areas, the server can enter the waiting allocation state for the target order and suspend allocation for the target order. The feeding port is in a deliverable state.

Step 506: In response to detecting the target situation, select a feeding port area as a new target feeding port area, and allocate the delivery port in the new target feeding port area to the target order. Execute step 508.

Wherein, when the target situation includes a feeding port in a deliverable state in any of the multiple feeding port areas, the new target feeding port area is a feeding port area where a feeding port in a deliverable state exists; or , when the target situation includes the feeding port area corresponding to the frequency range of the target order and there is a feeding port in a deliverable state, the new target feeding port area is the feeding port area corresponding to the frequency range of the target order.

Feeding port. Based on the detection situation, a feeding port area is selected as the new target feeding port area, and the delivery port in the new target feeding port area is assigned to the target order. Among them, the implementation method of allocating the delivery port in the new target delivery port area to the target order can refer to the implementation process of selecting the delivery port in the target delivery port area from the target delivery port area and assigning it to the target order.

In an optional situation, the target situation includes the presence of a feeding port in a deliverable state in any of the multiple feeding port areas.

The server can detect whether there is a delivery port in all the feeding port areas. It is detected that there is a feeding port in a deliverable state in any feeding port area. Then select the feeding port area with a feeding port in a deliverable state as the new target feeding port area.

In another optional situation, the target situation includes that there is a feed port in a deliverable state in the feed port area corresponding to the frequency range of the target order.

The server can detect whether there is a delivery port in the target feeding port area corresponding to the target order frequency range. It is detected that a feeding port in a deliverable state exists in the area of the target feeding port. Then select the feeding port area with a feeding port in a deliverable state as the new target feeding port area.

Step 507: Select a feeding port area as a new target feeding port area, and allocate the delivery port in the new target feeding port area to the target order. Execute step 502.

For the explanation and implementation of step 507, reference may be made to the explanation and implementation of step 404, which will not be described again in this embodiment of the present invention.

For the explanation and implementation of step 508, reference may be made to the explanation and implementation of step 303, which will not be described again in this embodiment of the present invention.

Step 509: Before the delivery of the goods in the target order is completed, if the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, other feeding ports in the deliverable state are reallocated to the target order.

For the explanation and implementation of step 509, reference may be made to the explanation and implementation of step 302, which will not be described again in this embodiment of the present invention. Among them, the explanation and implementation method of the server allocating other feeding ports in a deliverable state for the target order can be implemented in the aforementioned steps of the server allocating the feeding ports in a deliverable state for the target order, or the server side can allocate other feeding ports in a deliverable state to the target order according to the aforementioned steps 501 to 507. The frequency range to which the delivery times of the goods in the target order belong is determined. The target feeding port area corresponding to the frequency range among the multiple feeding port areas is determined. The server selects the delivery port in the target feeding port area and assigns it to the target order. The implementation method is not described in detail in the embodiment of the present invention.

As can be seen from the above embodiment, in this embodiment, when receiving an outbound task for a target order, a delivery port is assigned to the target order, and the transportation device is controlled to deliver the goods in the target order to the allocated Feeding port. Before the delivery of the goods in the target order is completed, if the status of the feeding port assigned to the target order changes from the deliverable state to the undeliverable state, other feeding ports in the deliverable state will be reallocated for the target order, and the transportation device will be controlled. The goods in the target order are delivered to other feeding ports. In this technical solution, before the delivery of the goods in the target order is completed, if the feeding port fails or the feeding port container is closed due to any situation such as being full, the status of the feeding port assigned to the target order will be changed from the deliverable state to the undeliverable state. status, you can allocate other feeding ports in the deliverable state to the target order, realizing flexible allocation between the target order and the feeding ports. This avoids the problem in the related technology that due to the fixed allocation of the target order and the feeding port, the transport device can only be in a waiting state when the state of the feeding port allocated to the target order is in an undeliverable state. It improves the working efficiency of the transportation device, shortens the sorting time of target orders, and improves picking efficiency.
