[0034] Figure 1 An exemplary architecture 100 of a cargo retrieval method and device for a cargo storage and retrieval system to which the present application may be applied is shown.

[0035] like Figure 1 As shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104 and a server 105. The communication connection between the terminal devices 101, 102, 103 constitutes a topological network, and the network 104 is used to provide a medium for the communication link between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0036] The terminal devices 101, 102, 103 can interact with the server 105 through the network 104 to receive or send data, etc. The terminal devices 101, 102, 103 can be hardware devices or software that support network connection for data interaction and data processing. When the terminal devices 101, 102, 103 are hardware, they can be various electronic devices that support network connection, information acquisition, interaction, display, processing and other functions, including but not limited to vertical rails, cargo platforms, transfer vehicles, etc. in cargo storage systems. When the terminal devices 101, 102, 103 are software, they can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules for providing distributed services, for example, or it can be implemented as a single software or software module. No specific limitation is made here.

[0037] The server 105 may be a server that provides various services, for example, a background processing server that sends operation instructions to the terminal devices 101, 102, 103 to control their operation. As an example, the server 105 may be a cloud server.

[0038] It should be noted that the server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules (for example, software or software modules used to provide distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0039] It should also be noted that the cargo outbound method applied to the cargo storage and retrieval system provided in the embodiments of the present application is generally executed by a server, but the possibility of being executed by a terminal device, or being executed by the server and the terminal device in cooperation with each other, is not excluded. Accordingly, the various parts (such as various units) included in the cargo outbound device applied to the cargo storage and retrieval system can be all set in the server, or all set in the terminal device, or can be set in the server and the terminal device respectively.

[0040] It should be understood that Figure 1 The number of terminal devices, networks and servers in the above description is only for illustration. Any number of terminal devices, networks and servers may be provided as required. When the electronic device on which the cargo outbound method applied to the cargo storage and retrieval system is running does not need to perform data transmission with other electronic devices, the system architecture may only include the electronic device (e.g., server or terminal device) on which the cargo outbound method applied to the cargo storage and retrieval system is running.

[0041] Continue to refer Figure 2 , shows a process 200 of an embodiment of a cargo outbound method applied to a cargo storage and retrieval system.

[0042] In order to clearly explain the cargo outbound method applied to the cargo storage and retrieval system, the cargo storage and retrieval system is first described as follows: Continue to refer Figures 3A-3D , shows a schematic diagram of the structure of the cargo storage and retrieval system. Figure 3A The three-dimensional structural diagram of the cargo storage and retrieval system is shown. Figure 3B shows a side view of a cargo access system, Figure 3C shows a top view of the cargo storage and retrieval system, Figure 3D Shows a complete structural diagram of the cargo storage and retrieval system.

[0043] The cargo storage and retrieval system includes a workstation, a shelf 302, a storage and retrieval device for transporting cargo between the storage location and the temporary storage location of the shelf, and a transfer device for transferring cargo between the temporary storage location and the workstation. The storage and retrieval device is, for example, a cargo platform 304 located outside the shelf and running on the shelf, and the transfer vehicle runs based on the unit area on the running plane to transfer the cargo with the cargo platform. For example, the cargo platform can be operated horizontally and vertically along the outside of the shelf by a hanging basket device; for another example, the shelf is provided with a horizontal track and a vertical track, and the cargo platform can run horizontally along the outside of the shelf through the horizontal track, and run vertically along the outside of the shelf through the vertical track. The transfer device is, for example, a transfer vehicle 301.

[0044] A workstation can be physical or virtual. It is the final stop for the transfer equipment to complete the task of outbound delivery of goods. It is a location where staff or other equipment can dock with the outbound delivery equipment. Its main function is to ensure that the goods can be accurately delivered from the shelves in the warehouse to the designated processing area. Whether it is the actual physical space corresponding to the physical workstation or the logical operation site represented by the virtual workstation, they play a key role in the entire outbound delivery process. They are like transfer stations for goods to enter the subsequent circulation links from inventory. They are of great significance to improving the efficiency and accuracy of outbound delivery. They will be reasonably set and adjusted according to factors such as the layout of the warehouse, business needs, and the degree of automation to meet the requirements of outbound delivery of goods of different sizes and types.

[0045] In some implementations, the access device in the cargo access system also includes a vertical rail 303 located outside the shelf and can run in the horizontal direction, and the cargo platform can run along the vertical rail in the vertical direction. The unit area is an area with a certain area obtained by dividing the operation plane, such as a grid. The operation objects such as the transfer vehicle, the vertical rail, and the cargo platform can set the corresponding authority for the unit area, and the operation object that has set the authority of the unit area is exclusive to other operation objects that want to set the authority for the unit area and have the possibility of collision with the operation object. Specifically, the authority setting is, for example, the vertical rail and the cargo platform set the prohibited operation state for the unit area, and the transfer vehicle obtains the operation authority of the unit area. After the vertical rail and the cargo platform set the prohibited operation state for the unit area, the transfer vehicle that has the possibility of collision with the vertical rail and the cargo platform cannot run on the unit area in the prohibited operation state; after the transfer vehicle obtains the operation authority of the unit area, the vertical rail that has the possibility of collision with the transfer vehicle cannot run above the unit area, and the cargo platform that has the possibility of collision with the transfer vehicle does not run to the target position close to the operation plane of the transfer vehicle.

[0046] Continue to refer Figure 4 , shows a schematic diagram of the operation process of the vertical rail and the cargo platform on the shelf. Specifically, Figure 4It shows the operation process of the cargo platform running from the storage location 305 to the storage location 306 or the temporary storage location 307 to perform the task.

[0047] Combined with the horizontal operation of the vertical rail and the vertical operation of the cargo platform, the cargo platform can carry out the operation of moving goods into (storing) or out (taking out) any storage location on the shelf, and hand over the goods with the transfer vehicle on the running plane. The transfer vehicle can directly contact the cargo platform to hand over the goods, or it can use indirect contact to hand over the goods.

[0048] Continue to refer Figure 3B The shelves in the cargo storage and retrieval system are generally arranged opposite to each other in pairs, and lanes are set between the shelves. When the transfer vehicle needs to hand over goods with the loading platform based on the temporary storage position, it generally needs to run vertically in the length direction of the lane to run below the temporary storage position. The transfer vehicle is provided with a lifting mechanism, and goods can be placed on the lifting mechanism. In the process of storing goods on the shelf, when the transfer vehicle carrying goods runs to the bottom of the shelf according to its corresponding running route, the lifting mechanism is raised, and it runs vertically in the length direction of the lane to place the goods in the temporary storage position below the bottom storage position of the shelf. The loading platform can place the goods on the temporary storage position into the target storage position on the shelf. In the process of taking out goods from the shelf, the vertical rails and the loading platform cooperate with each other to place the goods on the shelf in the temporary storage position on the shelf. After the transfer vehicle runs vertically in the length direction of the lane to the bottom of the temporary storage position, the lifting mechanism is raised to lift the goods to place the goods on the lifting mechanism, and then backs up to the lane, lowers the lifting mechanism, and transports the goods to the designated destination.

[0049] For shelves arranged opposite to each other, vertical rails and cargo platforms can be set on one of the shelves, and temporary storage locations can be set below the lowest storage locations of the other shelf. Therefore, during the horizontal operation of the vertical rails, the transfer vehicle only transfers cargo to the temporary storage locations on the opposite shelf, so that there is no possibility of collision between the vertical rails and the transfer vehicle.

[0050] Continue to refer Figure 5 , shows a schematic diagram of the transfer vehicle handing over goods based on the temporary storage position and the cargo platform. For shelves arranged opposite to each other, temporary storage positions can be set below the bottom storage positions of both shelves, and vertical rails and cargo platforms are only set on one of the shelves. It can be understood that increasing the number of temporary storage positions helps to improve the storage and retrieval efficiency of the cargo storage and retrieval system. Figure 6 , showing another top view schematic diagram of the cargo storage and retrieval system of this embodiment.

[0051] Process 200 includes the following steps: Step 201: Generate replenishment suggestions corresponding to orders in an order set, and add the replenishment suggestions to a replenishment suggestion set.

[0052] In this embodiment, the execution entity can generate replenishment suggestions corresponding to the orders in the order set, and add the replenishment suggestions to the replenishment suggestion set. The replenishment suggestions are used to represent the quantity of target goods corresponding to the order that needs to be replenished from the storage location to the temporary storage location, and the replenishment suggestions generated based on orders at different process nodes have different priorities.

[0053] For all orders that need to ship out the corresponding goods, they can be added to the order set. For example, for a goods storage and retrieval system, orders are received in real time or at a fixed time, and the received orders are added to the order set.

[0054] For each order in the order set, a replenishment suggestion corresponding to the order can be generated based on the quantity of target goods required for each order, and the replenishment suggestion can be added to the replenishment suggestion set. For example, for order A, the corresponding goods required are a, and its replenishment suggestion is (a, 2), which means that the quantity of goods a in the temporary storage location cannot meet the demand for goods a in the order, and 2 pieces of goods a need to be transported from the storage location to the temporary storage location.

[0055] The execution entity may generate corresponding replenishment suggestions for each order in the order in which the orders are generated. When the orders in the order set have different priorities, the processing order of the orders in the order set may be determined in the order from high to low priority and in combination with the order in which the orders are generated.

[0056] All unprocessed replenishment suggestions are added to the replenishment suggestion collection. The priorities of replenishment suggestions generated based on orders at different process nodes are different. For example, when generating replenishment suggestions based on orders, the longer the time between the process node where the order is located and the time node of the shipment, the lower the priority of the replenishment suggestion; on the contrary, the shorter the time between the process node where the order is located and the time node of the shipment, the higher the priority of the replenishment suggestion.

[0057] In some optional implementations of this embodiment, the execution subject may execute the generation process of the replenishment suggestion in step 201 as follows: The first step is to generate a replenishment suggestion corresponding to the order according to the quantity of the target goods corresponding to the order and the quantity of the target goods in the shelf.

[0058] As an example, after determining the quantity of target goods corresponding to the order and the quantity of target goods in the shelf, a target shelf is selected from shelves where the quantity of target goods is greater than the quantity of target goods corresponding to the order, and a replenishment suggestion corresponding to the order is generated based on the quantity of target goods in the target shelf.

[0059] The second step is to determine the priority of replenishment suggestions based on the process node where the order is located.

[0060] As an example, the execution entity may determine the time length between the process node where the order is located and the time node of shipment; the longer the time length is, the lower the priority of the replenishment suggestion is; conversely, the shorter the time length is, the higher the priority of the replenishment suggestion is.

[0061] In this implementation, a method for generating replenishment suggestions is provided, which combines the replenishment suggestions and their priorities to improve the information richness and accuracy of the replenishment suggestions.

[0062] In some implementations of this embodiment, the execution subject may perform the second step in the following manner: 1. In response to the order being at a process node that is not assigned to a workstation, determining the priority of the replenishment suggestion to be the third priority.

[0063] When an order is at a process node that is not assigned to a workstation, the generated replenishment suggestion can be named a normal replenishment suggestion. The goods storage and retrieval system still has sufficient time to prepare for the order's outbound delivery, and its priority is the lowest.

[0064] 2. In response to the order being at a process node assigned to a workstation, determining the priority of the replenishment suggestion to be the second priority.

[0065] When an order is at a process node assigned to a workstation, the generated replenishment suggestion can be named order replenishment suggestion with medium priority.

[0066] 3. In response to the order being at a process node where the transfer equipment is executing an outbound task, and the transfer equipment has not determined a temporary storage location for the target goods from the goods storage and retrieval system, the priority of the replenishment suggestion is determined to be the first priority.

[0067] Among them, the first priority is higher than the second priority, and the second priority is higher than the third priority.

[0068] When the order is at the process node where the transfer equipment performs the outbound task, the generated replenishment suggestion can be named as an emergency replenishment suggestion, which has a higher priority. It can be understood that when the order is at the process node where the transfer equipment performs the outbound task, and the transfer equipment has not determined the temporary storage location for the target goods from the cargo access system, it indicates that there is already a transfer task for the transfer equipment to perform the order, but the transfer equipment is in an abnormal state where it has not determined the temporary storage location for the target goods from the cargo access system, and cannot continue to perform the transfer task. At this time, the generated replenishment suggestion should have a higher priority.

[0069] In this implementation, three specific representations corresponding to orders at different process nodes and their respective priorities are provided, which improves the rationality of replenishment suggestions and helps to improve outbound efficiency.

[0070] In some implementations of this embodiment, the execution entity may perform the first step in the following manner: generate a replenishment suggestion based on the quantity of target goods corresponding to the order, the quantity of target goods in each storage location, and the quantity of target goods in each temporary storage location.

[0071] For order replenishment suggestions, the generation process is as follows: First, query the orders that have been assigned to the workstation but whose corresponding goods have not been located from the storage location to obtain the order list; summarize the goods of the orders in the order list to determine the type and demand of the goods. Then, traverse each required goods and calculate the respective replenishment quantity.

[0072] For general replenishment suggestions, the generation process is as follows: First, query the orders that have not been assigned to the workstation and get the order list; summarize the goods of the orders in the order list to determine the type and demand of the goods. Then, traverse each required goods and calculate the respective replenishment quantity.

[0073] For emergency replenishment suggestions, when the transfer equipment executes the replenishment task corresponding to the order according to the order priority, it finds that there is no inventory of the goods corresponding to the order in the temporary storage location of the goods storage and retrieval system, then an emergency replenishment suggestion is generated based on the demand quantity of each goods in the order.

[0074] The replenishment quantity of the replenishment suggestion can be determined as follows: Assuming the total inventory of the storage location of the goods is , the total inventory of temporary storage is , the order demand is ,if No replenishment is required, that is, the replenishment quantity is 0; if The replenishment quantity is , the generated replenishment suggestion is {product code, replenishment quantity}.

[0075] In this embodiment, a specific method for generating replenishment suggestions of each priority level is provided, thereby improving the accuracy of the generated replenishment suggestions.

[0076] Step 202: Generate a replenishment task corresponding to the replenishment suggestion according to the priority of the replenishment suggestion in the replenishment suggestion set, and execute the replenishment task through the storage and access device.

[0077] In this embodiment, the execution subject can generate a replenishment task corresponding to the replenishment suggestion according to the priority of the replenishment suggestion in the replenishment suggestion set, and execute the replenishment task through the storage and access device. The replenishment task is used to instruct the storage and access device to transport the goods corresponding to the replenishment task from the storage location to the temporary storage location.

[0078] As an example, the execution subject may determine the processing order between the replenishment suggestions in the replenishment suggestion set according to the priority of the replenishment suggestions in the replenishment suggestion set; process the replenishment suggestions in sequence according to the processing order, and generate replenishment tasks corresponding to the replenishment suggestions. Specifically, the execution subject needs to determine the candidate storage locations where the goods in the replenishment suggestions are placed from the storage locations on the shelf. When there are multiple candidate storage locations, it is necessary to determine the target storage location from the multiple candidate storage locations, and determine the target temporary storage location from the temporary storage locations on the shelf where the target storage location is located. Then, the goods corresponding to the replenishment task are transported from the target storage location to the target temporary storage location through the storage and access device.

[0079] As another example, the execution entity may determine the processing order of the replenishment suggestions in the replenishment suggestion set according to the priorities of the replenishment suggestions in the replenishment suggestion set and the order in which the replenishment suggestions were generated; replenish the suggestions in order according to the processing order, and generate replenishment tasks corresponding to the replenishment suggestions.

[0080] In the storage and temporary storage locations of the shelves, multiple goods of the same type are generally contained in containers. When executing a replenishment task, the container in the target storage location can be transported to the temporary storage location through the storage and retrieval device. After the replenishment task is generated, the status of the container on the target storage location is adjusted to replenishment and handling, and the inventory of the corresponding goods in the temporary storage location is increased according to the replenishment quantity, and the inventory of the corresponding goods in the storage location is deducted.

[0081] The conditions for determining the target storage location and the conditions for determining the target storage location can be specifically set according to actual conditions. For example, the conditions for determining the target storage location include, for example, satisfying the replenishment demand of the order based on the goods in one target storage location as much as possible, and the conditions for determining the target temporary storage location include, for example, ensuring that the distance between the determined temporary storage location and the workstation is as small as possible.

[0082] The storage and retrieval equipment is generally set on the shelf, and the corresponding relationship between the shelves is fixed. After the target storage location and the target temporary storage location are determined, the storage and retrieval equipment on the shelf where the target storage location and the target temporary storage location are located performs the replenishment task, that is, transports the goods in the target storage location to the target temporary storage location.

[0083] In some implementations of this embodiment, before executing step 202, the execution subject may further perform the following operation: merging replenishment suggestions corresponding to the same type of goods according to the priorities of the replenishment suggestions in the replenishment suggestion set.

[0084] In some cases, replenishment suggestions for the same type of goods may be generated repeatedly. In this case, replenishment suggestions for the same type of goods need to be merged according to the priorities of the replenishment suggestions in the replenishment suggestion set.

[0085] As an example, in response to determining that the replenishment suggestion set includes at least two replenishment suggestions corresponding to the same type of goods, and the at least two replenishment suggestions have the same priority, the at least two replenishment suggestions are merged, that is, only the replenishment suggestion with the largest quantity among the at least two replenishment suggestions is retained in the replenishment suggestion set.

[0086] In this implementation, by merging replenishment suggestions corresponding to the same type of goods, duplicate generation of replenishment tasks is avoided, thereby improving the accuracy and reliability of warehouse delivery.

[0087] In some implementations of this embodiment, the execution entity may execute the replenishment suggestion merging process in the following manner: In response to the replenishment suggestion set including other replenishment suggestions of the same type as the goods corresponding to the newly added replenishment suggestion, and the priorities of the other replenishment suggestions are higher than or equal to the priority of the newly added replenishment suggestion, only the replenishment suggestion with a larger quantity among the newly added replenishment suggestion and the other replenishment suggestions is retained in the replenishment suggestion set.

[0088] When replenishment suggestions are generated based on the orders in the order set, each replenishment suggestion generated is added to the replenishment suggestion set.

[0089] For a newly added common replenishment suggestion, when the replenishment suggestion set includes other replenishment suggestions of the same type as the goods corresponding to the common replenishment suggestion, only the newly added common replenishment suggestion and the replenishment suggestion with a larger quantity among the other replenishment suggestions are retained in the replenishment suggestion set.

[0090] For a newly added order replenishment suggestion, when the replenishment suggestion set includes other replenishment suggestions of the same type as the goods corresponding to the order replenishment suggestion, and the other replenishment suggestions are order replenishment suggestions or emergency replenishment suggestions, only the newly added order replenishment suggestion and the replenishment suggestion with a larger quantity among the other replenishment suggestions are retained in the replenishment suggestion set.

[0091] For a newly added urgent replenishment suggestion, when the replenishment suggestion set includes other replenishment suggestions of the same type as the goods corresponding to the urgent replenishment suggestion, and the other replenishment suggestions are urgent replenishment suggestions, only the newly added urgent replenishment suggestion and the replenishment suggestion with a larger quantity among the other replenishment suggestions are retained in the replenishment suggestion set.

[0092] In this implementation, a merging scenario of replenishment suggestions is provided, which improves the adaptability of the merging process of replenishment suggestions to the inventory outbound scenario and improves the accuracy of the merging process.

[0093] In some implementations of this embodiment, the execution entity may execute the replenishment suggestion merging process in the following manner: In response to the replenishment suggestion set including other replenishment suggestions of the same type as the goods corresponding to the newly added replenishment suggestion, and the priorities of the other replenishment suggestions are lower than the priority of the newly added replenishment suggestion, the priorities of the other replenishment suggestions are increased to the priority of the newly added replenishment suggestion, and only the replenishment suggestion with a larger number between the newly added replenishment suggestion and the other replenishment suggestions is retained in the replenishment suggestion set.

[0094] For a newly added order replenishment suggestion, when the replenishment suggestion set includes other replenishment suggestions of the same type as the goods corresponding to the order replenishment suggestion, and the other replenishment suggestions are common replenishment suggestions, the common replenishment suggestions are adjusted to order replenishment suggestions, and only the replenishment suggestions with larger quantities among the newly added order replenishment suggestions and the newly adjusted order replenishment suggestions are retained in the replenishment suggestion set.

[0095] For a newly added urgent replenishment suggestion, when the replenishment suggestion set includes other replenishment suggestions of the same type as the goods corresponding to the urgent replenishment suggestion, and the other replenishment suggestions are order replenishment suggestions or common replenishment suggestions, the order replenishment suggestions or common replenishment suggestions are adjusted to urgent replenishment suggestions, and only the replenishment suggestions with larger quantities between the newly added urgent replenishment suggestions and the newly adjusted urgent replenishment suggestions are retained in the replenishment suggestion set.

[0096] In this implementation, another merging scenario of replenishment suggestions is provided, which improves the adaptability of the merging process of replenishment suggestions to the inventory outbound scenario and improves the accuracy of the merging process.

[0097] In some implementations of this embodiment, the above-mentioned execution entity can execute the generation process of the replenishment task in the above-mentioned step 202 in the following manner: in response to the existence of a first storage location in the storage locations of the cargo storage and retrieval system, a replenishment task is generated according to the first storage location and a first preset generation condition.

[0098] The first storage location includes goods corresponding to the replenishment suggestion, and the quantity of the included goods is greater than or equal to the quantity corresponding to the replenishment suggestion.

[0099] Among them, the first preset generation condition can be specifically set according to the actual situation of the cargo storage and retrieval system, for example, including the quantity balance between the replenishment tasks in each lane in the cargo storage and retrieval system, and keeping the distance between the temporary storage location where the goods are transported and the workstation as small as possible.

[0100] As an example, compare the number of items in each storage location of the shelf and the demand for the product as recommended by the replenishment ,if , then add the storage location to the collection ; If P is not empty, check the lane where each storage location in the set P is located, and select the storage location in the lane with the least replenishment tasks.

[0101] In this implementation, a specific generation scenario of replenishment tasks is provided, which improves the rationality of the generated replenishment tasks and helps to improve the efficiency of the replenishment process.

[0102] In some implementations of this embodiment, the above-mentioned execution entity can execute the generation process of the replenishment task in the above-mentioned step 202 in the following manner: in response to the fact that the first storage location does not exist in the storage locations of the cargo storage and retrieval system, a replenishment task is generated according to the second storage location and in accordance with the second preset generation condition.

[0103] The second storage location includes the goods corresponding to the replenishment suggestion, and the quantity of the included goods is less than the quantity corresponding to the replenishment suggestion.

[0104] Among them, the second preset generation condition can be specifically set according to the actual situation of the cargo storage and retrieval system, for example, including the quantity balance between the replenishment tasks in each lane in the cargo storage and retrieval system. When the goods in one storage location cannot meet the replenishment suggestion, the replenishment suggestion is met based on as few storage locations as possible.

[0105] As an example, compare the number of items in each storage location of the shelf and the demand for the product as recommended by the replenishment ,if , then add the storage location to the collection ; will gather The storage locations are sorted from large to small according to their respective goods quantity, and added to the replenishment task set R in sequence until the sum of the inventory quantities of the goods contained in R is greater than or equal to .

[0106] In this implementation, another specific generation scenario of replenishment tasks is provided, which improves the rationality of the generated replenishment tasks and helps to improve the efficiency of the replenishment process.

[0107] In some implementations of the present embodiment, the first preset generation condition and the second preset generation condition include that the proportion of temporary storage locations occupied by replenishment tasks in each lane is lower than a first preset threshold, and among the temporary storage locations occupied by replenishment tasks, the proportion of temporary storage locations occupied by replenishment tasks with the lowest priority is lower than a second preset threshold.

[0108] The first preset threshold and the second preset threshold can be specifically set according to actual conditions. For example, the first preset threshold is 50% and the second preset threshold is 20%.

[0109] In order to prevent outbound containers from filling up the temporary storage space and affecting the return of goods to the warehouse, the proportion of temporary storage space occupied by replenishment tasks in each lane shall not exceed 50%. At the same time, ordinary replenishment tasks shall occupy a maximum of 20% of the temporary storage space in the lane, and temporary storage spaces shall be reserved for order replenishment tasks and emergency replenishment tasks.

[0110] In this implementation, the first preset generation condition and the second preset generation condition limit the occupancy of the temporary storage location based on the preset threshold value, thereby avoiding the occurrence of unreasonable situations and helping to improve the operating efficiency of the cargo storage and retrieval system.

[0111] Step 203, through the transfer equipment, according to the priority of the order in the order set, execute the transfer task corresponding to the order to ship the target goods corresponding to the order out of the warehouse.

[0112] In this embodiment, the execution subject can execute the transfer task corresponding to the order through the transfer device according to the priority of the order in the order set, so as to remove the target goods corresponding to the order from the warehouse. The transfer task is used to instruct the transfer device to transfer the goods corresponding to the transfer task from the temporary storage location to the workstation.

[0113] As an example, the execution subject can determine the execution order of the transfer tasks corresponding to the orders in the order set according to the priority of the orders in the order set; and execute the transfer tasks in sequence through the transfer equipment according to the execution order. Specifically, the transfer equipment locates the target temporary storage location where the goods in the transfer task are located, and runs to the target temporary storage location, and transfers the goods in the target temporary storage location to the workstation for the staff in the workstation to pick the goods and perform the outbound operation.

[0114] In some cases, the goods in one target temporary storage location cannot meet the order requirements. In this case, multiple transfer devices are required in one transfer task to transfer goods from multiple target temporary storage locations.

[0115] Assume that the total inventory of one type of goods in the temporary storage location on the shelf is The total storage inventory is The order quantity required is ,if However, there is no shelf container with available inventory in the temporary storage location, which means that there is a replenishment task waiting for the storage and retrieval device to replenish the inventory; if and , then the replenishment quantity is ;if and , then the replenishment quantity is , the order picking variance quantity is .

[0116] After the transfer equipment has successfully located the container in the storage location, the status of the container is adjusted to being transported out of the warehouse. After the container, transfer equipment and workstation are successfully matched, the transfer task is issued to the transfer equipment.

[0117] The transfer equipment moves the goods from the temporary storage location to the workstation. After picking is completed, the transfer equipment moves the container to the temporary storage location, and the container status is changed to put on the shelf.

[0118] In some implementations, the storage and retrieval equipment and the transfer equipment can also be combined to perform the warehousing task. The workstation receives the warehousing task, controls the transfer equipment to the workstation to receive the incoming goods, and the transfer equipment moves the incoming goods to the temporary storage location. After the goods are put on the shelves, the goods storage and retrieval system increases the total inventory of the temporary storage location according to the replenishment quantity, and changes the status of the replenishment container to put on the shelves.

[0119] Continue to see Figure 7 , Figure 7 FIG. 7 is a schematic diagram 700 of an application scenario of a method for removing goods from a cargo storage and retrieval system according to this embodiment. Figure 7 In the application scenario, the cargo storage and retrieval system 701 includes a workstation, a shelf, a storage and retrieval device for transporting cargo between the storage location and the temporary storage location of the shelf, and a transfer device for transferring cargo between the temporary storage location and the workstation.

[0120] The server 702 interacts with the cargo access system 701 in real time to determine the running route, running position and running status of the transfer vehicle, vertical rail and cargo platform. The server 702 generates replenishment suggestions corresponding to the orders in the order set, and adds the replenishment suggestions to the replenishment suggestion set, wherein the replenishment suggestions are used to characterize the number of target goods that need to be replenished from the storage location to the temporary storage location in the target goods corresponding to the order, and the priority of the replenishment suggestions generated based on the orders at different process nodes is different; according to the priority of the replenishment suggestions in the replenishment suggestion set, the replenishment tasks corresponding to the replenishment suggestions are generated, and the replenishment tasks are executed through the access device, wherein the replenishment tasks are used to instruct the access device to transport the goods corresponding to the replenishment tasks from the storage location to the temporary storage location; through the transfer device, according to the priority of the order in the order set, the transfer tasks corresponding to the orders are executed to ship out the target goods corresponding to the orders, wherein the transfer tasks are used to instruct the transfer device to transfer the goods corresponding to the transfer tasks from the temporary storage location to the workstation.

[0121] The method provided by the above-mentioned embodiment of the present application generates replenishment suggestions corresponding to the orders in the order set, and adds the replenishment suggestions to the replenishment suggestion set, wherein the replenishment suggestions are used to characterize the quantity of target goods that need to be replenished from the storage location to the temporary storage location among the target goods corresponding to the order, and the priorities of the replenishment suggestions generated based on the orders at different process nodes are different; according to the priorities of the replenishment suggestions in the replenishment suggestion set, a replenishment task corresponding to the replenishment suggestion is generated, and the replenishment task is executed by the access device, wherein the replenishment task is used to instruct the access device to transport the goods corresponding to the replenishment task from the storage location to the temporary storage location; through the transfer device, according to the priorities of the orders in the order set, the transfer task corresponding to the order is executed to ship out the target goods corresponding to the order, wherein the transfer task is used to instruct the transfer device to transfer the goods corresponding to the transfer task from the temporary storage location to the workstation, and a cargo shipping method with the coordinated operation of multiple access devices and multiple transfer devices is provided, which ensures the flexibility and reliability of the cargo shipping process based on the priorities of the replenishment suggestions and the transfer tasks while improving the shipping efficiency.

[0122] In some implementations of this embodiment, the above-mentioned execution entity may also perform the following operations: in response to the occupancy rate of the temporary storage locations set adjacent to the aisles in the shelves being greater than a third preset threshold, and there being a target temporary storage location where the goods included in the occupied temporary storage locations can be returned to the storage location, the goods in the target temporary storage location are transported to the storage location through the storage and retrieval equipment that has completed the replenishment task in the aisles.

[0123] The third preset threshold may be specifically set according to actual conditions, for example, the third preset threshold is 30%.

[0124] The above execution entity can filter the containers without order requirements in the temporary storage location, and these containers can be returned to the storage location. When the container in the temporary storage location is returned to the storage location, the goods storage and retrieval system deducts the total inventory of the corresponding goods in the temporary storage location and increases the total inventory of the corresponding goods in the storage location.

[0125] If there are no containers that can be returned to the storage location, the storage and retrieval equipment performs a single outbound operation. If there are containers that can be returned to the storage location, the truck will prioritize the double-circulation operation, that is, after moving one container from the storage location to the temporary storage location, the other container is moved from the temporary storage location to the storage location. If there are containers that can be returned to the storage location and there is no replenishment task, the storage and retrieval equipment performs a single inbound operation.

[0126] If the idle rate of temporary storage locations in the aisle is >70%, the storage and retrieval device does not need to return to the storage location; if the idle rate of temporary storage locations is <70%, the container with the lowest sales volume will be found in the aisle and returned to the storage location.

[0127] In this implementation, the access device preferentially executes the dual-cycle operation, which helps to improve the operation efficiency of the access device.

[0128] Continue to refer Figure 8 , shows a schematic process 800 of another embodiment of a cargo outbound method applied to a cargo storage and retrieval system according to the present application, comprising the following steps: Step 801: Generate a replenishment suggestion corresponding to the order according to the quantity of target goods corresponding to the order in the order set and the quantity of target goods in the shelf, and add the replenishment suggestion to the replenishment suggestion set.

[0129] Step 802, determining the priority of replenishment suggestions according to the process node where the order is located.

[0130] Step 803: In response to the replenishment suggestion set including other replenishment suggestions of the same type as the goods corresponding to the newly added replenishment suggestion, and the priorities of the other replenishment suggestions are higher than or equal to the priority of the newly added replenishment suggestion, only the newly added replenishment suggestion and the replenishment suggestion with a larger number among the other replenishment suggestions are retained in the replenishment suggestion set.

[0131] Step 804: In response to the replenishment suggestion set including other replenishment suggestions of the same type as the goods corresponding to the newly added replenishment suggestion, and the priorities of the other replenishment suggestions are lower than the priority of the newly added replenishment suggestion, the priorities of the other replenishment suggestions are increased to the priority of the newly added replenishment suggestion, and only the newly added replenishment suggestion and the replenishment suggestion with a larger number among the other replenishment suggestions are retained in the replenishment suggestion set.

[0132] Step 805: Generate a replenishment task corresponding to the replenishment suggestion according to the priority of the replenishment suggestion in the replenishment suggestion set, and execute the replenishment task through the storage and access device.

[0133] Among them, the replenishment task is used to instruct the storage and retrieval device to transport the goods corresponding to the replenishment task from the storage location to the temporary storage location.

[0134] Step 806, through the transfer equipment, according to the priority of the order in the order set, execute the transfer task corresponding to the order to ship the target goods corresponding to the order out of the warehouse.

[0135] Among them, the transfer task is used to instruct the transfer equipment to transfer the goods corresponding to the transfer task from the temporary storage location to the workstation.
