[0002] With the continuous expansion and deepening of modern production scale, warehouses have become an indispensable part of production and material management systems. Stereoscopic warehouses, with their small footprint and high space utilization, are gradually replacing old and backward flat warehouses with low area utilization and becoming important logistics nodes in modern logistics systems. They are increasingly used in logistics centers. At present, the world's tallest stereoscopic warehouse has a height of 50 meters. The storage capacity per unit area of ​​a stereoscopic warehouse can reach 7.5 (t / m2), which is 5 to 10 times that of an ordinary warehouse.

[0003] However, in the prior art warehouse management system, when a pallet is put into storage, the number of the material stored on the pallet and the quantity of the corresponding material are input; when materials need to be taken out, all materials in the pallet are taken out of the storage (the total number of materials stored in the pallet in the inventory is 0), and the remaining quantity of the material in the pallet is obtained when the pallet is returned after the material is taken out. In this way, a pallet in the three-dimensional warehouse managed by the management system can only store one type of material, resulting in low space utilization of the pallet and fewer types of goods stored in the three-dimensional warehouse.

[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] The present invention aims at solving the existing problems and provides a management system for an intelligent stereoscopic warehouse.

[0021] like Figure 1 As shown, an embodiment of the present invention provides a management system for an intelligent three-dimensional warehouse, including: A partitioning module is used to partition the internal space of each free pallet in the target stereoscopic warehouse to obtain a cargo space partitioning result; The scanning module is used to scan the barcode of the material to be stored and obtain the data information of the material to be stored, including the material number, specification, quantity and size; A screening module is used to screen the cargo spaces in the cargo space division result according to the data information to obtain a plurality of cargo spaces that meet the requirements; A calculation module is used to obtain the position information of the pallet to which each cargo space that meets the requirements belongs in the target stereoscopic warehouse, and calculate the distance from the current access point to the pallet to which each cargo space that meets the requirements belongs according to the position information to obtain multiple distance values; A selection module is used to select the storage compartment with the smallest distance value from all the storage compartments that meet the requirements as the optimal shelf position according to each distance value; The warehousing module is used to place the materials to be stored in the optimal shelf position through laser guidance, update the database and generate a storage order to complete the material storage; The outbound module is used to dispatch pallets according to the material picking list, pick up materials and generate an outbound order to complete the material outbound.

[0022] like Figure 2 As shown, in an embodiment of the present invention, a partitioning module can be used to virtually divide different cargo compartments inside each free pallet. The number of partitions can be 1, 3, 7, 21, etc., and the sizes of the divided cargo compartments can be the same or different.

[0023] It should be noted that in actual operation, if the quantity or volume of materials to be stored changes, the number of cargo spaces can be adjusted and divided in real time according to actual usage. However, before adjustment, it is necessary to ensure that there are no materials stored in the adjusted pallets. This division method improves the flexibility of pallet space use and ensures that warehouse space is always used in the most effective way. A variety of cargo space division methods can meet the storage needs of different materials. Whether it is small or large materials, they can find cargo spaces of appropriate size for storage, which reduces the gaps between materials and avoids space waste. It also helps to improve the efficiency of material retrieval and retrieval.

[0024] It should be noted that, in the embodiment of the present invention, different materials can be stored in the same cargo space, or the same material can be stored, but only one batch of the same material can be stored.

[0025] Specifically, if Figure 3 As shown, the screening module includes: The first screening unit is used to screen out all the cargo slots whose maximum size is close to the size of the material to be stored in the cargo slot division result according to the size of the material to be stored; A calculation unit, for calculating, for each screened cargo space, the absolute value difference between the maximum size of the cargo space and the size of the material to be stored; A sorting unit is used to sort all the screened cargo slots according to the calculated absolute value difference, and take the cargo slots corresponding to the absolute value difference less than the preset threshold as the candidate cargo slots; The selection unit is used to select multiple storage locations that meet the requirements from the alternative storage locations according to the quantity and specifications of the materials to be stored.

[0026] In the embodiment of the present invention, the principle of the sorting unit is that when no cargo slots with similar height dimensions and satisfying the storage quantity are screened out, a pallet with no material stored and a current height of 0 is screened out as an alternative cargo slot.

[0027] Specifically, laser guidance is used to place the materials to be stored in the optimal shelf position, including: The center point coordinates of the optimal shelf position are calculated based on the cargo space division results and the pallet size. The laser guidance head guides the materials to be stored to the optimal shelf position through the center point coordinates.

[0028] Specifically, the center point coordinates of the optimal shelf location are calculated based on the cargo space division results and the pallet size, including: According to the result of the cargo grid division, the pallet corresponding to the optimal shelf position is divided into m rows and n columns; According to the coordinates of the lower left corner of the pallet corresponding to the optimal racking position ( ) and the upper right corner coordinates ( ), calculate the width of the pallet corresponding to the optimal racking position and height , the calculation expression is: By the width of the pallet corresponding to the optimal racking position and height , calculate the width of the optimal shelf position And height, the calculation expression is: According to the width of the optimal shelf position and height , calculate the lower left corner coordinates of the optimal shelf position ( ) and the center point coordinates ( ).

[0029] Specifically, laser guidance is used to place the materials to be stored in the optimal shelf position, including: Call the laser guidance head API according to the center point coordinates; The laser guidance head emits a laser beam to the center point of the target cargo space to achieve visual guidance; Operators deposit materials quickly and accurately according to the guidance of the laser beam; When storing and retrieving materials, use the laser guidance head to guide to the center of the designated cargo space. Through visual guidance, materials can be stored quickly and accurately, saving operation time, reducing the probability of errors, improving the accuracy and timeliness of warehouse entry, enhancing the intelligent level of warehouse management, and improving logistics efficiency.

[0030] In an embodiment of the present invention, after the operator places the materials into the designated area according to the laser guidance, the database immediately updates the data records in the material storage details table of the storage location, saves the warehousing information to the material storage details table of the storage location, and generates documents such as purchase entry orders or other entry orders to complete the warehousing process.

[0031] It should be noted that the database in the embodiment of the present invention is stored in the storage module of the intelligent three-dimensional warehouse.

[0032] Specifically, the database includes: The pallet information table is used to record the number (Tray-ID) of each pallet, the supported shelf type (Shelf-Type), and the maximum height (Max Material Height) of the material that can be stored. This information is crucial for warehouse management because it determines the use and storage capacity of the pallet. The maximum height means that when calculating the automatic warehousing, the height of the stored material can be as close as possible to the height of the shelf to save three-dimensional space. A reasonable range (such as 0~25 cm) is set according to the actual storage and access port position of the three-dimensional warehouse; The storage slot status table is used to record the occupancy status of each storage slot. By querying this table, you can quickly understand which storage slots are free and which are occupied, thereby optimizing the material storage and retrieval process.

[0033] The material storage record table is used to record the material information stored in each storage slot. The table contains key information such as the material ID, specification, quantity, storage status, and creation time. It is used to accurately track and manage the materials in each storage slot. The storage status includes in-stock, out-of-stock, etc. The storage space capacity table is used to record the capacity of each storage space. When new materials need to be put on the shelves, the minimum storage space type required can be quickly determined based on the data in this table, thereby optimizing storage space and improving storage efficiency, providing key data support for the automatic shelving system.

[0034] Specifically, if Figure 4 As shown, the outbound module includes: The scanning unit is used to scan the barcode on the material picking list to obtain the material picking details, which include the production order number, material number, specification, unpicked quantity, and picked quantity; The second screening unit is used to screen out the storage records of the materials to be shipped out in the material storage record table according to the material picking details, and to build a cache table for pending operations according to the storage records; A rearrangement unit is used to merge material records of the same pallet by traversing the cache table to be processed to obtain an updated cache table to be processed, and to rearrange the updated cache table to be processed according to the position information of all pallets in the updated cache table to be processed to obtain a rearranged cache table to be processed; The outbound unit is used to call out the pallet according to each storage record in the rearranged cache table to be operated, pick up the materials and generate an outbound order to complete the outbound delivery of the materials.

[0035] In the embodiment of the present invention, a cache table of pending operations is constructed according to the storage records and initialized to obtain an empty cache table of pending operations for storing information of materials to be shipped out; Then compare the material quantity in the material storage record table with the quantity to be shipped out in the material picking details; If the material quantity in the material storage record table meets or exceeds the quantity to be shipped, the relevant information of the record (such as the row ID of the material storage detail table of the cargo location, material code, order number, etc.) is written into the cache table for pending operations, and the next material picking detail is processed; If the material quantity in the record is insufficient, the next material storage record will be taken out for comparison until a record that meets the quantity is found and written into the pending job cache table.

[0036] In the embodiment of the present invention, the priority queue is used to rearrange the updated cache table of pending jobs according to the storage time to obtain the rearranged cache table of pending jobs, so as to realize the first-in-first-out management.

[0037] The embodiment of the present invention uses a spatial indexing technology (such as an R-tree or a quadtree, etc.) to optimize and sort the pallet location information, and rearranges the cache table of pending operations in order from near to far, so as to improve the outbound efficiency.

[0038] Specifically, the outbound unit is also used to: When taking out the material in the current pallet, the next pallet is synchronously called out according to the next storage record.

[0039] The embodiment of the present invention processes each record in a loop according to the sorted cache table of pending jobs; Automatically call the API interface of the high-bay warehouse to call out the pallet, and use laser guidance to accurately guide the operator to the location where the material is to be picked up; At the same time, the material picking scheduling uses dual pallets for simultaneous scheduling. When the current pallet is waiting for the operator to pick up the material at the discharge port, the API instruction for the next pallet is called. After the three-dimensional warehouse automatically takes the next pallet, it waits at the discharge port. This method reduces the waiting time for personnel and improves the execution efficiency of material outbound delivery.

[0040] Specifically, the outbound module also includes: The update module is used to update the database after the material is shipped out.

[0041] Specifically, after the operator takes out the required materials according to the laser guidance, the database immediately updates the data records in the material storage details table of the cargo location, deducts the quantity of materials that have been shipped out, and generates documents such as material picking lists or other shipping lists to complete the shipping process.

[0042] The embodiment of the present invention divides the internal space of each free pallet in the target stereoscopic warehouse by using a partitioning module; then uses a scanning module to scan the barcode of the material to be stored to obtain the data information of the material to be stored; uses a screening module to screen the storage compartments in the storage compartment partition result according to the data information to obtain a plurality of storage compartments that meet the requirements; obtains the position information of the pallet to which each storage compartment that meets the requirements belongs in the target stereoscopic warehouse by using a calculation module, and calculates the distance from the current access point to the pallet to which each storage compartment that meets the requirements belongs according to the position information to obtain a plurality of distance values; uses a selection module to select the storage compartment with the smallest distance value from all the storage compartments that meet the requirements as the optimal shelf position according to each distance value; and uses a laser to guide the storage compartments to be stored. The materials are placed in the optimal shelf position, the database is updated and an entry form is generated to complete the material entry; the outbound module calls out the pallet according to the picking form, takes the materials and generates an outbound form to complete the material outbound; compared with the prior art, the embodiment of the present invention uses a partitioning module to divide each idle pallet, and increases the number of cargo spaces when the number of pallets is limited, which can not only reduce the gaps between materials and avoid space waste, but also improve the flexibility of pallet space use; the screening module selects cargo spaces from the cargo space partition results for storage according to the data information of the materials to be entered, which is equivalent to storing different materials in different cargo spaces in the same pallet, solving the problem of low space utilization of pallets in intelligent stereoscopic warehouses and a small number of stored goods.

[0043] It should be noted that the division of the above-mentioned functional units and modules is illustrated by way of example. In practical applications, the above-mentioned functions can be assigned to different functional units and modules as needed. Each functional unit and module can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one unit. The above-mentioned integrated unit can be implemented in the form of hardware or in the form of software functional units. In addition, the specific names of the functional units and modules are only for the convenience of distinguishing each other, and are not used to limit the scope of protection of this application.
