[0029] The method, apparatus, and storage medium for determining warehouse retrieval routes provided in this application are described in detail below with reference to the accompanying drawings.

[0030] The term "and / or" in this document is only used to describe associated objects, which means that there can be three relationships, for example, A and / or B can represent three cases: A exists alone, A and B exist together, and B exists alone.

[0031] The terms "first" and "second" and the like in the description of the present application and the drawings are used to distinguish different objects, or to distinguish different treatments of the same object, and are not used to describe a specific order of the objects.

[0032] In addition, the terms "include" and "have" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0033] It should be noted that in the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Rather, the use of "exemplary" or "for example" is intended to present relevant concepts in a concrete manner.

[0034] In the prior art, the method of warehouse management is usually to divide the shelves according to the categories of goods, and design them in layers. At the same time, the goods are placed in the corresponding shelf category area according to the categories. In order to facilitate the management of warehouse goods, the corresponding relationship between the shelf number and the goods number is usually established when the goods are put into the warehouse, and the corresponding relationship is saved in the warehouse management system. When a picking device needs to pick goods, it is usually necessary to input the information such as the category of goods or the number of goods into the warehouse management system for inquiry. Correspondingly, the warehouse management system matches and returns the information such as the shelf number where the goods are located through the information such as the category of goods or the number of goods. At the same time, the warehouse management system generates the corresponding picking path according to the location information of the picking device and the location information of the shelf. However, this picking path generation method often requires strong computing power, increasing the management cost of warehouse management.

[0035] In related technologies, such as the patent with application number 202211575058.X, the method disclosed in the patent is as follows: The method includes: constructing a site model and setting multiple marker reference points in the site model; acquiring reader movement data and reading data, dividing the reader movement data according to the time of reading operation in the reading data to obtain independent movement data; parsing the independent movement data to determine the movement path between each tag and the corresponding marker reference point; and marking the site model according to the movement path of each tag to mark the position of each item in the site model.

[0036] However, the patent fails to distinguish between the two stages of goods traveling along the path and goods being placed on the shelf, making the calculation of the path and the destination position uncertain. Furthermore, the data collection process—"if A is a reference point and B is the goods, then the reader first reads the label of A, then the label of B, then the label of A again, at which point the data collection for one item is complete"—is overly cumbersome.

[0037] Therefore, how to reduce the computational complexity of generating the target pickup route has become an urgent technical problem to be solved.

[0038] To address the aforementioned technical problems, this application provides a method for determining warehouse retrieval routes. The method includes: acquiring the RFID tag corresponding to the target goods; identifying the target goods as goods to be retrieved; extracting the inbound path of the target goods based on the RFID tag; wherein the inbound path is the path of the target goods upon entering the warehouse, generated based on the location information of multiple RFID readers; determining the RFID reader whose location information meets preset conditions as the target RFID reader based on the location information of the target RFID reader; and determining the target retrieval route corresponding to the target goods based on the location information of the target RFID reader. In this way, by calculating the retrieval route based on the inbound path of the goods, the retrieval route is not only more reasonable but also reduces the complexity and computational requirements of calculating the target retrieval route. Thus, the technical problem of how to reduce the computational complexity of generating the target retrieval route is solved.

[0039] This application provides a method for determining warehouse pickup routes, which can be applied to, for example... Figure 1 The warehouse pickup route determination device 10 shown includes: a goods entry module 101, an RFID signal acquisition module 102, a route generation module 103, a warehouse map module 104, a route query module 105, and a route query client 106.

[0040] The goods entry module 101 is used for entering the correspondence between goods and RFID identification. The goods refer to physical entities with independent identification positions, such as a commodity or a packaging box of a group of commodities. Specifically, the goods entry module 101 enters the basic information of the goods into the warehouse management system, such as the identification of the goods, the category, the name, the specification, and the like. Further, the RFID tag on the goods is read by the RFID reader, and the correspondence between the tag identification and the goods identification is established and saved.

[0041] The RFID signal collection module 102 is an RFID signal reader deployed in the stereoscopic warehouse, which is used to determine the deployment density of the reader according to the size of the warehouse and the positioning accuracy. For example, at the entrance of the goods warehouse, on the main aisle of the warehouse, on the backbone support of the goods shelf, and the like. The path experienced by the goods during the warehousing process is collected by the above-mentioned RFID signal collection module 102. The RFID signal collection module includes a plurality of RFID signal readers. The plurality of RFID signal readers can be fixedly deployed on fixed positions, or can be mobile signal readers. For example, the mobile signal reader is deployed on the delivery vehicle.

[0042] The route generation module 103 is based on the warehouse map to pre-establish the correspondence between the RFID signal collection module 102 and the position on the warehouse map. When the goods are warehoused, the warehousing path is generated in the map according to the group of RFID signal collection modules 102 passed through and the RFID tag corresponding to the goods shelf grid where the goods are placed. The corresponding goods shelf RFID tag on the goods shelf grid is used to deploy the RFID tag on each shelf grid according to the accuracy requirement, so as to accurately identify the placement position of the goods.

[0043] The warehouse map module 104 is used to record the positions of the facilities to be identified, such as the goods shelves, the levels of the goods shelves, and the aisles, so as to generate the navigation route for the person or the delivery robot.

[0044] The route query module 105 is used to input the category or the identification of the goods, and return the recommended goods taking route.

[0045] The route query client 106 is used to collect the information input by the user, such as the identification of the goods or the category of the goods, and the current position information of the mobile terminal, and generate the query result of the goods taking route.

[0046] As Figure 2Fig. 7 is a structural schematic diagram of another warehouse goods taking path determination device provided by an embodiment of the present application. The warehouse goods taking path determination device 200 includes at least one processor 201, a communication line 202, and at least one communication interface 204, and can further include a memory 203. The processor 201, the memory 203, and the communication interface 204 can be connected through the communication line 202.

[0047] The processor 201 can be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement one or more embodiments of the present application, such as one or more digital signal processors (DSPs), or one or more field programmable gate arrays (FPGAs).

[0048] The communication line 202 can include a path for transmitting information between the above-mentioned components.

[0049] The communication interface 204 is configured to communicate with other devices or communication networks, and can use any transceiver device, such as an Ethernet, a radio access network (RAN), a wireless local area network (WLAN), and the like.

[0050] The memory 203 can be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disk storage, a magneto-optical disk, a magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited thereto.

[0051] In one possible design, the memory 203 can exist independently of the processor 201, meaning the memory 203 can be an external memory of the processor 201. In this case, the memory 203 can be connected to the processor 201 via the communication line 202 to store execution instructions or application code, and its execution is controlled by the processor 201 to implement the space measurement determination method provided in the following embodiments of this application. In another possible design, the memory 203 can also be integrated with the processor 201, meaning the memory 203 can be an internal memory of the processor 201. For example, the memory 203 can be a cache, which can be used to temporarily store some data and instruction information.

[0052] As one possible implementation, processor 201 may include one or more CPUs, for example Figure 2 CPU0 and CPU1 in the example. Alternatively, the warehouse pickup route determination device 200 may include multiple processors, such as... Figure 2 The processors 201 and 207 are included. Alternatively, the warehouse retrieval route determination device 200 may also include an output device 205 and an input device 206.

[0053] Through the above description of the implementation methods, those skilled in the art will clearly understand that, for the sake of convenience and brevity, only the division of the above functional modules is used as an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the network node can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the system, modules, and network nodes described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.

[0054] Figure 3 This is a flowchart illustrating a method for determining a warehouse retrieval route, provided in an embodiment of this application, and applied to a device for determining a warehouse retrieval route. Figure 3 As shown, the determination of the warehouse pickup route provided in this application embodiment can be achieved through the following steps 301 to 304.

[0055] Step 301: Obtain the RFID tag corresponding to the target goods.

[0056] The target goods are those awaiting pickup.

[0057] In one possible implementation, the warehouse pickup route determination device obtains the RFID tag corresponding to the goods to be picked up from the warehouse management system based on information such as the goods identification and goods category of the target goods.

[0058] In an example, the picking device sends the information such as the product identifier and the product category of the product to be picked to the warehouse picking path determination apparatus via a mobile terminal. Correspondingly, the warehouse picking path determination apparatus receives the information such as the product identifier and the product category of the product to be picked sent by the product query mobile terminal. Further, the warehouse picking path determination apparatus queries the correspondence table between the product information and the RFID identifier from the warehouse management database based on the information such as the product identifier and the product category of the product to be picked, so as to determine the RFID identifier corresponding to the product to be picked.

[0059] It should be noted that the picking device can be a product administrator or a picking robot or the like.

[0060] In step 302, the storage path of the target product is extracted based on the RFID identifier.

[0061] In a possible implementation, the warehouse picking path determination apparatus extracts the storage path of the product to be picked when the product to be picked is stored in the warehouse management system. The storage path is a path of the target product when the target product is stored based on the position information of a plurality of RFID readers. It should be noted that the plurality of RFID readers are fixed readers deployed in the warehouse in advance, and the position of each RFID reader is determined. The storage path is generated based on the position information of the plurality of RFID readers of the target product identifier collected when the target product is stored.

[0062] In an example, the warehouse picking path determination apparatus obtains the storage path of the product to be picked from the warehouse map module based on the RFID identifier of the product to be picked, wherein the storage path is a path generated based on the position information of a plurality of RFID readers deployed in the warehouse and collecting the RFID identifier of the product to be picked.

[0063] Specifically, as shown in Table 1, the storage path information table of the target product is shown.

[0064] Table 1, the storage path information table of the target product

[0065]

[0066] In step 303, the RFID reader whose position information satisfies the preset condition is determined as the target RFID reader based on the position information of the plurality of RFID readers in the storage path.

[0067] In a possible implementation, the warehouse picking path determination apparatus determines the RFID reader whose position information satisfies the preset condition as the target reader based on the position information of the plurality of RFID readers in the storage path.

[0068] In an example, the warehouse picking path determination apparatus determines the RFID reader closest to the location of the picking device as the target RFID reader based on the location information of the plurality of RFID readers in the storage path.

[0069] It should be noted that the picking device has a corresponding RFID identifier. The RFID identifier corresponding to the picking device is used by the warehouse picking path determination apparatus to determine the current location information of the picking device.

[0070] In step 304, the target picking path corresponding to the target goods is determined based on the location information of the target RFID reader.

[0071] In a possible implementation, the warehouse picking path determination apparatus determines the path from the location of the target RFID reader in the storage path to the end location of the goods to be picked as the target picking path of the goods to be picked based on the location information of the target RFID reader in the storage path.

[0072] In an example, refer to Table 1. If the target RFID reader is the A02 reader, the target picking path of the goods to be picked is A02-B01-C01. The information in the target picking path includes but is not limited to the travel route from the current location of the picking device to the location of the goods on the warehouse map, location coordinates, and the like.

[0073] The above scheme at least brings the following beneficial effects: obtaining the wireless radio frequency identification (RFID) identifier corresponding to the target goods; the target goods are the goods to be picked; based on the RFID identifier, extracting the storage path of the target goods; the storage path is a path generated based on the location information of a plurality of RFID readers when the target goods are stored; based on the location information of the plurality of RFID readers in the storage path, determining the RFID reader whose location information meets the preset condition as the target RFID reader; and based on the location information of the target RFID reader, determining the target picking path corresponding to the target goods. In this way, the picking path is calculated based on the storage path when the goods are stored, which not only makes the picking path more reasonable, but also reduces the complexity and computational power requirements for calculating the target picking path. Thus, the technical problem of how to reduce the calculation complexity of generating the target picking path is solved.

[0074] In combination Figure 3 As shown in Figure 4 The above step 304, based on the location information of the target RFID reader, determines the target picking path corresponding to the target goods, can be implemented through the following step 401:

[0075] In step 401, based on the location information of the target RFID reader, the path between the target RFID reader and the target goods in the storage path is selected as the target picking path.

[0076] In a possible implementation, the warehouse picking path determination apparatus selects, according to the position information of the target RFID reader, a path between the target RFID reader and the target goods from the storage path as the target picking path. The position of the target RFID reader in the target picking path is the starting position of the target picking path.

[0077] An example is shown in FIG. 2. As shown in FIG. 2, a storage path of target goods is shown. The storage path of the target goods is C1-C2-C3-C4. It should be noted that C1, C2, C3 and C4 are position numbers corresponding to RFID readers. When the target reader is C2, the target picking path of the target goods is C2-C3-C4. Figure 5 Specifically, as shown in FIG. 3, when the goods enter from the entrance RFID reader C1, they first pass through the RFID reader C2, then pass through the RFID reader C3, and finally are placed on the shelf. At the same time, the RFID reader C4 on the shelf detects. Further, according to the RFID reader identification and time sequence, the storage route of the goods is generated, and the route is saved to the warehouse map.

[0078] Figure 5 It should be noted that when the storage route needs to be queried, the warehouse management system obtains the route from the warehouse map and displays it on the mobile terminal of the picker or provides it to the picking robot as a basis for controlling the direction.

[0079] It should be noted that when the storage route needs to be queried, the warehouse management system obtains the route from the warehouse map and displays it on the mobile terminal of the picker or provides it to the picking robot as a basis for controlling the direction.

[0080] The above scheme at least has the following beneficial effects: the warehouse picking path determination apparatus selects, according to the position information of the target RFID reader, a path between the target RFID reader and the target goods from the storage path as the target picking path. In this way, the picking path is generated based on the storage path of the goods, which not only makes the picking path more reasonable, but also reduces the complexity and computational power requirements of calculating the target picking path.

[0081] In combination with Figure 3 As shown in FIG. 3, the above step 303, based on the position information of the plurality of RFID readers in the storage path, determines the RFID reader whose position information meets the preset condition as the target RFID reader, and can also be implemented through the following steps 601-602: Figure 6 Step 601, determine the first position information.

[0082] In a possible implementation, the warehouse picking path determination apparatus determines the first position information of the picking device. The first position information is used to represent the current position information of the picking device.

[0083] In a possible implementation, the warehouse picking path determination apparatus determines the first position information of the picking device. The first position information is used to represent the current position information of the picking device.​

[0084] In an example, the warehouse picking path determination apparatus reads the RFID identifier corresponding to the picking device based on the RFID signal collection module. Based on the RFID identifier corresponding to the picking device, the current position information of the picking device is determined.

[0085] Optionally, the picking device captures the identification code placed in the nearby position and sends the captured identification code information to the warehouse picking path determination apparatus. The warehouse picking path determination apparatus determines the current position information of the picking device according to the giant identification code information.

[0086] Step 602, based on the first position information, determining the RFID reader closest to the picking device in the plurality of RFID readers as the target RFID reader.

[0087] In a possible implementation, the warehouse picking path determination apparatus determines the RFID reader closest to the picking device from the plurality of RFID readers in the storage path corresponding to the picking device as the target RFID reader according to the first position information of the picking device.

[0088] The above scheme at least brings the following beneficial effects: the warehouse picking path determination apparatus determines the first position information of the picking device. The first position information is used to represent the current position information of the picking device. The warehouse picking path determination apparatus determines the RFID reader closest to the picking device from the plurality of RFID readers in the storage path corresponding to the picking device as the target RFID reader according to the first position information of the picking device. In this way, only the RFID reader closest to the current position of the picking device in the storage path is determined as the target reader, and the storage path from the reader to the position of the picking goods is used, which effectively reduces the complexity and computing power requirements of calculating the picking path.

[0089] In combination Figure 3 As shown in Figure 7 Before the above step 302, based on the RFID identifier, the storage path of the target goods is extracted, the following steps 701-703 are further included:

[0090] Step 701, obtaining the identifiers of the plurality of RFID readers and the shelf RFID identifier of the terminal position of the target goods.

[0091] In a possible implementation, the warehouse picking path determination apparatus obtains the identifiers of the plurality of RFID readers and the shelf RFID identifier of the terminal position of the target goods. The plurality of RFID readers are the RFID readers that collect the RFID identifier of the target goods when the target goods are stored.

[0092] An example, a plurality of RFID readers deployed in the warehouse detect the position information of the target goods in the detection range of the RFID signal in sequence. At the same time, the RFID reader is deployed in the shelf grid where the target goods are placed, which is used to determine the specific position of the RFID reader. The warehouse picking path determination device obtains the identification of a plurality of RFID readers and the shelf RFID identification of the target goods end position based on the RFID readers deployed in the warehouse and the shelf.

[0093] It should be noted that the warehouse entry path accuracy of the target goods is determined by the specifications of the RFID reader and the number of RFID readers deployed. Among them, the deployment position of the RFID reader needs to meet the condition that only one RFID reader can collect the RFID information of the goods at the same time.

[0094] Step 702, determine the position information of a plurality of RFID readers based on the identification of a plurality of RFID readers.

[0095] In a possible implementation manner, the warehouse picking path determination device determines the position information of a plurality of RFID readers through the identification information of a plurality of RFID readers received continuously.

[0096] An example, the warehouse picking path determination device matches the position information of the RFID reader deployed from the warehouse management database according to the received identification information of the RFID reader.

[0097] Optionally, the warehouse picking path determination device determines the position information of the RFID reader deployed in the warehouse management database from the three-dimensional warehouse map based on the identification information of the RFID reader.

[0098] Step 703, generate the warehouse entry path of the target goods based on the position information of a plurality of RFID readers and the shelf RFID identification of the target goods end position.

[0099] In a possible implementation manner, the warehouse picking path determination device generates the warehouse entry path of the target goods according to the position information of a plurality of RFID readers and the end position information of the target goods, that is, the shelf position information where the target goods are placed.

[0100] An example, the warehouse picking path determination device connects the position information of a plurality of RFID readers to generate the warehouse entry path information of the target goods based on the path generation module.

[0101] The above scheme has at least the following beneficial effects: the warehouse goods taking path determination device obtains the identification of the plurality of RFID readers and the shelf RFID identification of the target goods terminal position.
