Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

This embodiment can be applied to the situation of managing goods in smart shelves. The warehouse management method of the shelf provided in this embodiment can be executed by the warehouse management device of the shelf provided in the embodiment of the present application, which can be implemented by software and / or hardware and integrated in the electronic device and cargo dispatching system that executes the method. Preferably, the electronic device in the embodiment of the present application can be a smart phone, a tablet computer or a laptop computer, etc.

[0033] See also Figure 1 The method of this embodiment includes but is not limited to the following steps:

[0034] S110, obtaining storage information of goods on the shelves, goods information at the goods supply point, and attribute information of multiple transport vehicles.

[0035] Among them, the shelf in this application is a smart shelf, such as Figure 2 The figure shows a schematic diagram of the structure of the shelf. The upper part of the shelf is a storage area for storing goods, and the lower part is a sorting area for multiple transport vehicles to move and sort the goods. The storage area is divided into several different areas according to the size of the goods. The size of the grid in each area is different, and each grid stores one piece of goods. The sorting area has at least one layer of sorting platform, and each layer of sorting platform contains multiple sorting grids. Optionally, the shape of the shelf can be a three-dimensional rail shelf, a two-dimensional rail shelf or a stacked shelf. The storage information includes at least the basic information and storage information of the goods. The basic information includes the category, item number, production date, storage date, etc. The storage information refers to which numbered shelf grid a certain good is stored on. The goods information of the goods supply place includes the category, item number, production date, etc. The attribute information of the transport vehicle refers to the location information and status information of the current transport vehicle. The status information includes idle state and busy state.

[0036] Optionally, the cargo supply area includes a storage area, a temporary storage area, and an unpacking area. The supplier unloads the transported cargo in the storage area first, and then transports the cargo in boxes to the temporary storage area for storage. After receiving the replenishment request from the cargo dispatching system, the unpacking area performs unpacking and loads the cargo to be replenished. Figure 3 The figure shows a schematic diagram of the unpacking area, which is a top view. The unpacking area can be divided into a disassembly area, a buffer zone, and a replenishment port, which are connected by conveyor belts. The disassembly area is used to disassemble the whole box of goods into single items, which can be done manually. After the goods are disassembled manually, they are placed on the conveyor belt in order, and the conveyor belt transports the goods from the disassembly area to the buffer zone. The buffer zone is used to temporarily store disassembled goods. The goods are separated by a distance, and the equipment in the buffer zone can control each item to be transported to the replenishment port at the appropriate location and time. The buffer zone can use a cross-belt conveyor belt, and its layout can be designed as follows: Figure 3The ring on the left can also be designed as an S-shape on the right to save space. The replenishment port can be designed as a conveyor belt or a robotic arm to place the goods into the transport vehicle after receiving the replenishment request from the cargo dispatching system.

[0037] In an embodiment of the present application, the cargo dispatching system is respectively connected to the smart shelf, the electronic equipment at the cargo supply place and a plurality of transport vehicles through a communication connection mode, wherein the communication connection mode may be a controller area network communication or an Ethernet communication, or may be other communication connection modes. The smart shelf may obtain the storage information of the goods on the smart shelf at each preset time interval, and send the obtained storage information to the cargo dispatching system; or, the cargo dispatching system actively obtains the storage information of the goods through the smart shelf. The electronic equipment at the cargo supply place may send the cargo information to the cargo dispatching system at each preset time interval; or, the cargo dispatching system actively obtains the cargo information through the electronic equipment at the cargo supply place. The transport vehicle may send the location information and status information to the cargo dispatching system at each preset time interval; or, the cargo dispatching system actively obtains the location information and status information of the transport vehicle.

[0038] S120: Determine whether a replenishment operation needs to be performed on the goods according to the storage information and the goods information.

[0039] In the embodiment of the present application, after the cargo dispatching system obtains the storage information of the cargo on the shelf and the cargo information of the cargo supply place, it determines which cargo on the shelf needs to be replenished and the replenishment information of these cargoes that need to be replenished based on the storage information and the cargo information.

[0040] In some optional embodiments, determining whether a replenishment operation needs to be performed on the goods according to the storage information and the goods information includes: determining the remaining quantity of the goods according to the storage information, and if the remaining quantity of a certain kind of goods is less than a preset quantity, the goods dispatching system checks whether the goods exist at the goods supply place. If the goods exist at the goods supply place, it is determined that a replenishment operation needs to be performed on the goods, otherwise the goods dispatching system notifies the management personnel to replenish the goods at the goods supply place in a preset manner.

[0041] In some optional embodiments, determining whether it is necessary to perform a replenishment operation on the goods based on the storage information and the goods information also includes: if the current state is an off-season period for orders (i.e., a period with fewer orders), then predicting the goods that need to be replenished based on the storage information and historical order information, that is, there may be out-of-stock goods in the future, and determining that a replenishment operation needs to be performed on the goods when there are goods at the goods supply. The advantage of this setting is that replenishing a part of the goods can alleviate the replenishment pressure during peak periods. The present application can also use other replenishment rules to determine the goods that need to be replenished in the smart shelf.

[0042] S130: If a replenishment operation is required for the goods, the replenishment information of the goods is determined.

[0043] Among them, the replenishment information includes the category of goods, item number, quantity, shelf slot location of the goods, etc.

[0044] In the embodiment of the present application, after determining the goods in the smart shelf that need to be replenished in the above step S120, the goods dispatching system calculates the quantity of the goods to be replenished according to the remaining quantity of the goods.

[0045] S140. According to the replenishment information, the attribute information of the plurality of transport vehicles and the location information of the goods supply place, a target transport vehicle for performing a replenishment operation on the goods and a replenishment transportation path of the target transport vehicle are determined from the plurality of transport vehicles to control the target transport vehicle to perform the replenishment operation according to the replenishment transportation path.

[0046] The replenishment transport route includes the route information of the target transport vehicle and the time information of reaching each node in the route.

[0047] In the embodiment of the present application, after obtaining the replenishment information of the goods to be replenished in the above step S130, the cargo dispatching system first determines the target transport vehicle with idle status information from the multiple transport vehicles according to the status information of the multiple transport vehicles, so that the target transport vehicle performs the replenishment operation on the goods; then, a replenishment transportation path is formulated for the target transport vehicle according to the location information of the goods supply place, the location information of the target transport vehicle, and the shelf grid position in the replenishment information, and the replenishment transportation path is sent to the target transport vehicle. After receiving the replenishment transportation path, the target transport vehicle enters the busy state from the idle state, and moves from the waiting area to the replenishment port position of the unpacking area according to the replenishment transportation path to receive the goods, and then transports them to the designated shelf grid position to complete the replenishment operation in coordination with the shelf, and finally returns to the waiting area.

[0048] Optionally, when the transport vehicle is not performing a transport task (i.e., the status information is an idle state), it can be placed in a waiting area, and smart charging facilities can be configured in the waiting area to provide charging services for the transport vehicle.

[0049] Furthermore, in addition to performing replenishment operations on goods in the shelves, the warehouse management method of the shelves also includes performing picking and sorting operations on the goods in the shelves, specifically: obtaining order information from an order management system, and determining the starting and ending position information of each goods in the order information based on the storage information and the order information; determining a target transport vehicle for performing a picking operation on each goods in the order information and a picking transportation path of the target transport vehicle from multiple transport vehicles based on the starting and ending position information and attribute information of multiple transport vehicles, so as to control the target transport vehicle to perform the picking operation according to the picking transportation path.

[0050] Among them, the picking and sorting operation is roughly the reverse process of the replenishment operation. The order management system is a computer device integrated with the order information sent by the user. The order information includes the destination, category, number, quantity, etc. of the goods transported in the order; the starting and ending position information includes the shelf grid position and the sorting grid position; the picking and transportation route includes the route information of the transport vehicle and the time information of reaching each node in the route. One destination can correspond to one or more sorting grids.

[0051] In an embodiment of the present application, the cargo dispatching system is connected to the order management system through a communication connection. First, the order management system can send order information to the cargo dispatching system at each preset time interval, or the cargo dispatching system can actively obtain order information through the order management system. After the cargo dispatching system receives the order information, recent orders will be temporarily cached in an order pool. Then, the cargo dispatching system processes each order in the order pool in turn, and determines the shelf grid position and sorting grid position of each cargo in the order information according to the order information and storage information of a certain order. It should be noted that the order information may contain one or more cargoes, which are placed in one or more shelf grids, corresponding to one or more sorting grids. Secondly, the cargo dispatching system determines the target transport vehicle with idle status information from the multiple transport vehicles according to the status information of the multiple transport vehicles, so that the target transport vehicle performs a pickup operation on the cargo. Finally, the pickup transportation path formulated for the target transport vehicle according to the location information, shelf grid position and sorting grid position of the target transport vehicle is sent to the target transport vehicle together with the pickup command. After receiving the order to pick up goods and the transportation route, the target transport vehicle goes to the designated shelf according to the transportation route, connects to the shelf, moves to the designated shelf slot, takes out the goods, and then descends to the sorting layer to place the picked-up goods in the corresponding sorting slot. The same transport vehicle may pick up multiple goods in one sorting. If all goods are not picked up, it will go to the next shelf to pick up goods. Until all goods are picked up, the transport vehicle will move to the sorting slot corresponding to each goods, place all goods in turn, and then return to the waiting area to wait.

[0052] In an embodiment of the present application, the target transport vehicle climbs up on the shelf and picks up the goods, and the movement path of the goods is "shelf grid-transport vehicle-sorting grid". The movement path of the target transport vehicle is "waiting area-shelf grid-sorting area-waiting area". The movement of the transport vehicle from leaving the waiting area to returning to the waiting area is called a transport mission. A transport mission of the target transport vehicle can complete the delivery of only one piece of goods, or it can complete the delivery of multiple pieces of goods, which is determined by the accommodation space of the transport vehicle compartment and the volume of each piece of goods. Multiple pieces of goods can come from the same order or from multiple orders.

[0053] Furthermore, the shelf storage management method performs picking and sorting operations on the goods in the shelf and also includes: predicting the identification information of the destination of the order within a preset time period in the future based on the historical order information; and determining the number and position of the sorting grids corresponding to the destination in the sorting platform based on the identification information.

[0054] In an embodiment of the present application, a sorting grid corresponds to an order destination, and an order destination can correspond to one or more sorting grids. Before the cargo dispatching system controls the transport vehicle to sort the goods, the binding relationship between the sorting grid and the destination can be designed and adjusted as follows to ensure that the order processing speed of each sorting grid is relatively balanced and improve the overall efficiency: 1. One destination can be bound to multiple sorting grids. By analyzing the distribution information of order destinations in historical data, we can predict the destinations of new orders in the future. While ensuring that there is at least one sorting grid for each destination, for destinations with higher demand, we can allocate multiple sorting grids to them according to the proportion. 2. The position of the sorting grid can be adjusted, and the sorting grid with a larger order volume is set on the side close to the shelf, and the sorting grid with a smaller order volume is set on the side away from the shelf. In this way, the distance required for the sorting grid with a larger demand will be shortened, thereby improving the order processing rate.

[0055] Optional, such as Figure 4 The figure shows a schematic diagram of the road network of the sorting grid. The middle area surrounded by the road is the sorting grid, and the mobile unit cannot pass through it. When the mobile unit passes the road adjacent to the sorting grid, it can put the goods it carries into the sorting grid. There are entrances and exits for mobile units to enter / leave the road network at the edge of the road network. Under the condition that the number of sorting destinations N is known, a road network structure consisting of m horizontal passages and n vertical passages is designed. The number of sorting grids is (m-1)*(n-1), which should not be less than the number of sorting destinations N.

[0056] Optional, such as Figure 5 The figure shows a schematic diagram of the packaging and coding device. There is a packaging and coding device under each sorting grid. When all the goods required for an order are delivered, the packaging device under the sorting grid will pack all the goods into one package and label them. You can also use packaging paper / bags / boxes pre-printed with different barcodes. When the goods are fully assembled, the system associates the preset barcode with the corresponding order, eliminating the coding link. The sorting grid also has a transportation device (such as a conveyor belt) to transport the packaged packages to the shipping area, or to pack multiple packages into a large package and then transport them to the shipping area.

[0057] It should be noted that an order usually contains multiple goods, and these multiple goods need to be packaged in the same sorting grid; before the sorting grid starts to execute the collection task of this order and collects and packages all the goods of this order, the goods of other orders cannot enter this sorting grid for packaging. When the cargo dispatching system determines the sorting grid position of each cargo in the order information based on the storage information and order information, it needs to consider the situation that the sorting grid is occupied.

[0058] The technical solution provided by this embodiment obtains the storage information of the goods on the shelf, the goods information of the goods supply place and the attribute information of multiple transport vehicles; determines whether it is necessary to perform a replenishment operation on the goods according to the storage information and the goods information; if so, determines the replenishment information of the goods; determines the target transport vehicle and the replenishment transportation path of the target transport vehicle from the multiple transport vehicles according to the replenishment information, the attribute information of the multiple transport vehicles and the location information of the goods supply place, so as to control the target transport vehicle to perform the replenishment operation according to the replenishment transportation path. The present application can realize unmanned operation when processing the replenishment and picking and sorting of goods through the warehouse management method of the shelf, saves the space required for the workers' activities, reduces the necessary space for the cargo dispatching system to maintain operation, and makes the miniaturization of this kind of intelligent warehouse possible. The cargo dispatching system also avoids the efficiency constraints caused by the lack of manpower. Multiple purposes are achieved through the one-time delivery behavior of the mobile unit, the operation process is simplified, and the space utilization efficiency is further improved. The implementation of the present application solution can solve the problems of low shipping efficiency and high labor cost in the prior art, and can meet people's high efficiency requirements for replenishment operations and picking and sorting operations.

[0059] Embodiment 2

[0060] Figure 6 The second flow diagram of the storage management method of the shelf provided in the embodiment of the present application is as follows: The embodiment of the present application is optimized on the basis of the above embodiment, and the specific optimization is as follows: the present embodiment explains in detail the process of determining the target transport vehicle and the replenishment transport path.

[0061] See also Figure 6 The method of this embodiment includes but is not limited to the following steps:

[0062] S210, obtaining storage information of goods on the shelves, goods information at the goods supply point, and attribute information of multiple transport vehicles.

[0063] The attribute information of the multiple transport vehicles includes location information and status information.

[0064] Optional, such as Figure 2The figure shows a schematic diagram of the structure of the shelf. Various sensors (such as the positioning mark in the figure) are installed in each shelf grid, including infrared sensors, radio frequency identification modules (RFID), code scanning modules, etc. These sensors can be used to know whether the shelf grid is storing goods. If the shelf grid is storing goods, these sensors can obtain the storage information of the goods and upload the storage information to the cargo scheduling system so that the cargo scheduling system can schedule the goods later. There are multiple connection modules on the shelf, which are connected to the track on the side of the shelf. The transport vehicle can be fixed and moved relative to the shelf. The module is powered by the shelf or the transport vehicle itself. The horizontal track in the figure allows the transport vehicle to move horizontally on the shelf to ensure that the transport vehicle can access goods at any position on the shelf. There is a grabbing device on the transport vehicle, or there are active conveyor belts on the transport vehicle and the shelf, which can realize the transfer of goods between the shelf and the transport vehicle. The connection between the transport vehicle and the shelf can be positioned using a QR code or other methods to achieve precise control of the movement of the transport vehicle.

[0065] In an embodiment of the present application, the cargo dispatching system is respectively connected to the smart shelf, the electronic equipment at the cargo supply place and a plurality of transport vehicles through a communication connection mode, wherein the communication connection mode may be a controller area network communication or an Ethernet communication, or may be other communication connection modes. The smart shelf may obtain the storage information of the goods on the smart shelf at each preset time interval, and send the obtained storage information to the cargo dispatching system; or, the cargo dispatching system actively obtains the storage information of the goods through the smart shelf. The electronic equipment at the cargo supply place may send the cargo information to the cargo dispatching system at each preset time interval; or, the cargo dispatching system actively obtains the cargo information through the electronic equipment at the cargo supply place. The transport vehicle may send the location information and status information to the cargo dispatching system at each preset time interval; or, the cargo dispatching system actively obtains the location information and status information of the transport vehicle.

[0066] S220: Determine whether a replenishment operation needs to be performed on the goods according to the storage information and the goods information.

[0067] S230: If a replenishment operation is required for the goods, the replenishment information of the goods is determined.

[0068] Among them, the replenishment information includes the category of goods, item number, quantity, shelf slot location of the goods, etc.

[0069] S240. According to the attribute information of the multiple transport vehicles, a transport vehicle that is closest to the shelf opening and has idle status information is determined from the multiple transport vehicles to obtain a target transport vehicle.

[0070] In an embodiment of the present application, the cargo dispatching system selects a target transport vehicle suitable for performing a replenishment operation from multiple transport vehicles based on the location information of multiple transport vehicles. The criteria for selecting the target transport vehicle include at least: the current working state of the transport vehicle is an idle state, and the distance between the location information of the transport vehicle and the shelf grid position corresponding to the goods in a replenishment task is the shortest or within a preset distance range. The present application may also include other criteria for selecting the target transport vehicle, and the technicians implementing the present application scheme may set the criteria for selecting the target transport vehicle based on the actual operation situation.

[0071] Optionally, the embodiment of the present application may determine the number of transport vehicles to perform replenishment operations on the goods to be replenished according to the quantity of the goods to be replenished in the replenishment information and the volume and weight of the goods to be replenished.

[0072] In the prior art, when handling the tasks of replenishing and picking up goods, each shelf is served by one or more fixed transport vehicles. The embodiment of the present application determines the target transport vehicle that is closest to the shelf grid position and has idle status information from multiple transport vehicles based on the attribute information of multiple transport vehicles, that is, the transport vehicle that performs the transportation task can be any transport vehicle. This design can add a higher degree of freedom to order processing. The introduction of a transport vehicle selection algorithm can increase the processing speed of each order, reduce the average idle time of the transport vehicle, and reduce the investment cost of the transport vehicle.

[0073] S250: Determine a replenishment transportation route for the target transportation vehicle according to the location information of the target transportation vehicle, the location of the shelf slot, and the location information of the cargo supply point.

[0074] In an embodiment of the present application, after the target transport vehicle is determined in the above step S240, it is also necessary to determine the replenishment transportation route for the target transport vehicle based on the location information of the target transport vehicle (i.e., the location information of the waiting area), the shelf grid location, and the location information of the cargo supply point, and send it to the target transport vehicle to guide the target transport vehicle to travel.

[0075] S260. Determine whether there is a conflict point between the replenishment transportation path of the target transport vehicle and the replenishment transportation paths of other transport vehicles; if there is, do not perform the replenishment operation of the goods, reselect other goods and perform the replenishment operation of other goods; if not, send the replenishment transportation path to the target transport vehicle, and change the status information of the target transport vehicle from idle state to busy state.

[0076] Among them, other transport vehicles are transport vehicles other than the target transport vehicle among the multiple transport vehicles.

[0077] In the embodiment of the present application, after the replenishment transportation path of the target transport vehicle is determined in the above step S250, it is necessary to further determine whether the replenishment transportation path of the target transport vehicle is appropriate according to the road occupancy status at the current moment. For example, according to the replenishment transportation paths of other transport vehicles, determine whether there is a conflict point with the replenishment transportation path of the target transport vehicle; if there is a conflict point, the replenishment operation of the goods is temporarily not performed, and other goods are re-selected and the replenishment operation of other goods is performed; if there is no conflict point, the replenishment transportation path is sent to the target transport vehicle, and the status information of the target transport vehicle is changed from idle state to busy state.

[0078] It should be noted that when the shelf storage management method performs picking and sorting operations on the goods in the shelf, after determining the picking and transportation path of the target transport vehicle, it is also necessary to judge whether there is a conflict point between the picking and transportation path of the target transport vehicle and the picking and transportation paths of other transport vehicles. If there is a conflict point, the picking operation of the goods will not be performed, and other goods will be reselected and the picking operation of other goods will be performed; if not, the picking and transportation path will be sent to the target transport vehicle, and the status information of the target transport vehicle will be changed from idle to busy.

[0079] S270, controlling the target transport vehicle to perform replenishment operations according to the replenishment transport path.

[0080] The technical solution provided by the present embodiment obtains the storage information of goods on the shelf, the goods information at the goods supply point and the attribute information of multiple transport vehicles; determines whether it is necessary to perform a replenishment operation on the goods according to the storage information and the goods information; if so, determines the replenishment information of the goods; determines the transport vehicle that is closest to the shelf grid position and has idle status information from multiple transport vehicles according to the attribute information of the multiple transport vehicles, and obtains the target transport vehicle; determines the replenishment transportation path of the target transport vehicle according to the position information of the target transport vehicle, the shelf grid position and the position information of the goods supply point; determines whether there is a conflict point between the replenishment transportation path of the target transport vehicle and the replenishment transportation paths of other transport vehicles; if there is a conflict point, does not perform the replenishment operation of the goods, reselects other goods and performs the replenishment operation of other goods; if not, sends the replenishment transportation path to the target transport vehicle, and changes the status information of the target transport vehicle from idle to busy; controls the target transport vehicle to perform the replenishment operation according to the replenishment transportation path. This application can achieve unmanned operation when handling the replenishment and picking and sorting of goods through the warehouse management method of the shelf, saving the space required for workers' activities, reducing the necessary space for the system to maintain operation, and making it possible to miniaturize this type of intelligent warehouse. The cargo dispatching system also avoids the efficiency constraints caused by lack of manpower.
