Description

Technical Field

[0001] The present invention relates to the technical field of warehouse management, and particularly relates to an intelligent warehouse bin dynamic management method and system for material management. Background Art

[0002] With the continuous iteration of communication devices, the types of products are becoming more and more diverse, resulting in an increasing number, forms, and packages of products. Currently, the storage of communication devices mainly relies on manual management. Warehouse administrators manually select storage locations according to the material model specifications and inventory situations, and use forms or electronic records to maintain inventory information. However, manual judgment takes a long time, the efficiency of material storage is low, and it is easy to make mistakes, resulting in low efficiency of manual operations. Some warehouse management adopts the method of storing specific types of materials in fixed partitions, but the flexibility is poor. The fixed bin positions and static allocation methods do not fully utilize the warehouse space, resulting in serious fragmentation and low space utilization rate. There are also some warehouses equipped with barcode scanning devices and basic inventory management systems, but they fail to achieve dynamic allocation and recommendation of bin positions and lack intelligent management. Summary of the Invention

[0003] In order to overcome the defects existing in the above-mentioned prior art, the purpose of the present invention is to provide an intelligent warehouse bin dynamic management method and system for material management.

[0004] To achieve the above object of the present invention, the present invention provides an intelligent warehouse bin dynamic management method for material management, including the following steps:

[0005] Obtain the information of the material to be stored and the information of the remaining bin positions;

[0006] Calculate the matching degree between the material to be stored and each remaining bin position, the space utilization rate of each remaining bin position, and the operation convenience of each remaining bin position;

[0007] Set corresponding weights for the matching degree, space utilization rate, and operation convenience respectively, and construct a bin position scoring function, which is the sum of the matching degree, space utilization rate, and operation convenience;

[0008] Score the remaining bin positions based on the bin position scoring function, and store the material to be stored in the bin position with the highest score.

[0009] Optionally, calculate the turnover frequency of the material according to the number of times of inbound and outbound of the material, and dynamically adjust the storage area of the material between the high-frequency area and the low-frequency area according to the turnover frequency of the material.

[0010] Optionally, regularly check the fragmentation ratio of each bin position. The fragmentation ratio of the bin position is the ratio of the remaining volume of the bin position to the total available volume of the warehouse; if the fragmentation ratio of the bin position exceeds the threshold, reallocate the materials in the fragmented bin position.

[0011] Optionally, the matching degree between the material to be stored and the storage location is calculated as follows:

[0012] If the volume Vm of the material to be stored > the remaining volume Vw of the storage location, or the weight Wm of the material to be stored > the remaining load-bearing weight Ww of the storage location, then the matching degree between the material to be stored and the storage location is 0;

[0013] Otherwise, calculate the matching degree between the material to be stored and the storage location according to the formula to calculate the matching degree between the material to be stored and the storage location.

[0014] Optionally, the calculation steps for the space utilization rate of the storage location are as follows:

[0015] Calculate the absolute value of the difference between the volume of the material to be stored and the remaining space of the storage location;

[0016] Compare the volume of the material to be stored with the remaining volume of the storage location and select the larger one;

[0017] Obtain the ratio of the absolute value of the difference to the larger one. The closer this ratio is to 1, the lower the space utilization rate of the storage location, and the closer this ratio is to 0, the higher the space utilization rate of the storage location.

[0018] Optionally, the calculation steps for the operation convenience of the storage location are as follows:

[0019] Calculate the ratio between the distance from the storage location to the entrance and the maximum distance in the warehouse. The closer this ratio is to 1, the worse the operation convenience of this storage location, and the closer this ratio is to 0, the better the operation convenience of this storage location.

[0020] Optionally, dynamically display the dynamic changes of various inventories in the warehouse in real time;

[0021] and / or, perform voice broadcast on the materials to be stored or retrieved and their storage location information.

[0022] The present invention also provides a dynamic management system for the storage locations of an intelligent warehouse for material management, including:

[0023] Electronic tags, which are set on the materials and each storage location;

[0024] Electronic tag readers, which are used to read the electronic tags on the materials and / or storage locations to obtain material information and / or storage location information;

[0025] Transportation equipment, which is used for the transportation of materials and is communicatively connected to the processing module;

[0026] A processing module, the electronic tag reader is electrically connected to the processing module, and sends information of the materials and information of the storage positions to the processing module. The processing module allocates storage positions for the materials according to the information of the materials and the storage positions based on the above-mentioned dynamic management method for the storage positions of the intelligent warehouse for material management, and generates a path to send to the transportation equipment, and the transportation equipment transports the materials to the allocated storage positions.

[0027] Optionally, it further includes:

[0028] A display module, electrically connected to the processing module, and displays the dynamic changes of various inventories in the warehouse in real time;

[0029] A voice module, electrically connected to the processing module, and conducts voice broadcasts on the materials to be stored or retrieved and their storage position information.

[0030] The beneficial effects of the present invention are:

[0031] Through the intelligent recommendation and operation guidance for the storage positions of the materials, the present invention can not only reduce manual intervention, reduce the storage time, improve the efficiency, but also avoid mis-storage or wrong-storage problems; at the same time, by dynamically adjusting the storage positions and merging fragmented spaces, the utilization rate of the storage space is improved, and the space utilization is optimized; the accurate operation prompts are carried out through visualization and voice guidance, improving the access efficiency. Generally speaking, through intelligent management, combined with data analysis and dynamic optimization, the present invention realizes the efficient allocation of storage resources.

[0032] The additional aspects and advantages of the present invention will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present invention. Specific Embodiments

[0033] The embodiments of the present invention will be described in detail below.

[0034] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or the communication inside two components. It can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.

[0035] Embodiment 1

[0036] This embodiment provides a dynamic management method for the storage positions of an intelligent warehouse for material management.

[0037] The dynamic management method for the storage positions of the intelligent warehouse for material management is specifically as follows:

[0038] 1. First, perform hardware deployment and system initialization on the warehouse, specifically as follows:

[0039] 1.1. Warehouse Layout and Zoning Planning

[0040] The warehouse is divided into the following areas:

[0041] Receiving Area: Used for receiving and scanning materials;

[0042] Transportation Path Area: Set up a dedicated transportation channel for transportation equipment to transport materials, such as a dedicated transportation channel for Automated Guided Vehicle (AGV).

[0043] Storage Area: Divide the high-frequency area and the low-frequency area according to the material turnover rate.

[0044] An electronic tag, such as an RFID tag, is set up for each storage location.

[0045] Electronic tags can also be set up in the transportation path area and configured with path planning data to navigate transportation equipment.

[0046] 1.2. Deployment of Hardware Equipment

[0047] Electronic Reader: Deployed in the receiving area, used to read material and storage location information, such as an RFID reader. Electronic readers can also be set up in each storage area for use in the case of managing materials with RFID tags in the warehouse. Electronic readers can also be set up on transportation equipment.

[0048] Transportation Equipment: Used for automatic transportation of materials, configured with navigation and path planning functions, such as Automated Guided Vehicle (AGV);

[0049] Dynamic Sorting Platform: Automatically sort materials in the receiving area and transfer them to transportation equipment.

[0050] 1.3. Database Initialization:

[0051] Create databases for materials, storage locations, and transportation equipment:

[0052] Material Table: Record material information, including but not limited to tag ID, specifications, volume, weight, etc.;

[0053] Storage Location Table: Record the capacity, occupancy, and storage partition of each storage location;

[0054] Transportation Equipment Table: Record the status, location, and task queue of transportation equipment.

[0055] 2. Material Receiving and Sorting Operations

[0056] 2.1. Material Information Collection

[0057] In the receiving area, the electronic reader automatically scans the label of each material to obtain information such as its model, specifications, volume, weight, etc.;

[0058] The system verifies whether the materials are legal, such as whether they belong to the current warehouse or are available.

[0059] 2.2. Material sorting and classification:

[0060] The dynamic sorting platform classifies materials according to the material information:

[0061] In this embodiment, according to the number of times of incoming and outgoing of materials, the turnover frequency of materials is calculated, and the storage area of materials is dynamically adjusted between the high-frequency area and the low-frequency area according to the turnover frequency of materials.

[0062] Turnover frequency Among them, N o is the number of times of outgoing of materials within the statistical period; N t is the total number of operations (outgoing + incoming) of materials within the statistical period.

[0063] When P f ≥ the set high-frequency threshold θ, the materials are assigned to the high-frequency area; otherwise, they are assigned to the low-frequency area. The high-frequency area is generally the storage area close to the entrance and exit, and the low-frequency area is generally the storage area far from the entrance and exit.

[0064] After sorting is completed, the materials are transferred to the loading area of the transportation equipment.

[0065] 2.3. Automatic transportation and storage

[0066] 2.3.1. Task assignment to transportation equipment

[0067] The system assigns transportation tasks to each transportation equipment according to the status of the storage positions:

[0068] Storage position assignment: Combining the remaining capacity of the storage position, select the best storage position.

[0069] When assigning storage positions, according to the information of the materials to be stored and the information of the remaining storage positions, calculate the matching degree between the materials to be stored and each remaining storage position, the space utilization rate of each remaining storage position, and the operation convenience of each remaining storage position.

[0070] Among them, the calculation principle of the matching degree between the materials to be stored and the storage position is: If the volume Vm of the materials to be stored > the remaining volume Vw of the storage position, or the weight Wm of the materials to be stored > the remaining load-bearing weight Ww of the storage position, then the matching degree between the materials to be stored and the storage position is 0; otherwise, calculate the matching degree between the materials to be stored and the storage position according to the following formula.

[0071]

[0072] f1(ω,m) is the matching degree score between material m and storage position w, and its range is [0,1]. The closer it is to 1, the more suitable it is for storage.

[0073] Calculate the space utilization rate of the storage location, and preferentially select materials that can better fill the storage location space to reduce the generation of fragmented space. Specifically: calculate the absolute value of the difference between the volume of the material to be stored and the remaining space of the storage location; compare the volume of the material to be stored with the remaining volume of the storage location and select the larger one; obtain the ratio of the absolute value of the difference to the larger one. The closer this ratio is to 1, the lower the space utilization rate of the storage location, and the closer this ratio is to 0, the higher the space utilization rate of the storage location.

[0074] Therefore, this embodiment gives the calculation formula for the space utilization rate of the storage location:

[0075]

[0076] where f 2(w,m) is the space utilization efficiency score for material m stored in storage location w, and max(V w , V m ) is used to normalize the score range to [0, 1]. When the volume V m of the material to be stored is approximately equal to the remaining space V w of the storage location, the score is close to 1; when the volume difference between the two is large, the score decreases.

[0077] The operation convenience of the storage location mainly depends on its physical position. Calculate the ratio between the distance from the storage location to the entrance and the maximum distance in the warehouse. The closer this ratio is to 1, the worse the operation convenience of this storage location, and the closer this ratio is to 0, the better the operation convenience of this storage location.

[0078] Therefore, this embodiment gives the calculation formula for the operation convenience of the storage location:

[0079]

[0080] where f 3(w) is the operation convenience score for storage location w, d w is the distance from storage location w to the entrance; d max is the maximum distance in the warehouse, which is used for normalization. The closer the storage location is to the entrance, the higher the score, which is beneficial to improving the operation efficiency.

[0081] Perform storage location scoring by comprehensively matching the calculation results of matching degree, space utilization rate, and operation convenience. Specifically: set corresponding weights for the matching degree, space utilization rate, and operation convenience respectively, and construct a storage location scoring function, which is the sum of the matching degree, space utilization rate, and operation convenience.

[0082] Therefore, this embodiment gives the storage location scoring function as:

[0083] S w = α1·f1(w, m)+α2·f2(w, m)+α3·f3(w)

[0084] Among them, S w is the comprehensive score of the position w; α1, α2, and α3 are weight parameters that control the proportion of different scoring factors and satisfy α1 + α2 + α3 = 1;

[0085] All remaining positions are scored based on the position scoring function. After obtaining the scores S of all available positions w ∈ W w they are sorted in descending order of scores:

[0086]

[0087] W is the total number of positions, and W opt is the recommended position with the highest comprehensive score; recommend W opt as the storage location for the materials to be stored and display it on the terminal.

[0088] Path planning: Calculate the shortest path based on the current position of the transportation equipment and the target position.

[0089] 2.3.2. Automatic transportation and storage:

[0090] The transportation equipment transports the materials to the target position according to the planned path;

[0091] After arriving at the storage area, the electronic reader on the transportation equipment identifies the electronic tag on the position to confirm the target position, and then deposits the materials to be stored into the target position. Here, an automatic robotic arm can be activated to deposit the materials into the position, and the specific settings of the automatic robotic arm can be arranged using existing technologies.

[0092] 2.3.3. Storage completion and feedback:

[0093] · The sensor detects the position status and confirms that the materials have been stored;

[0094] Here, a weight sensor and / or a distance sensor can be used to detect the position status, including but not limited to the remaining volume Vw of the position and the remaining load-bearing weight Ww of the position. When using a weight sensor, the weight sensor is set at the bottom of the position to detect the weight of the materials already in the position, and then obtain the remaining load-bearing weight Ww of the position. When using a distance sensor, the distance sensor is set at the top of the position to detect the distance from the top of the position to the materials already stored, and then obtain the remaining volume Vw of the position. When the remaining volume Vw of the position and / or the remaining load-bearing weight Ww of the position decreases, it is confirmed that the materials have been stored.

[0095] · The transportation equipment returns to the standby area, and the system updates the position and material information to the database.

[0096] 2.4. Warehouse dynamic management

[0097] 2.4.1. High-frequency / low-frequency area adjustment:

[0098] Statistically calculate the turnover frequency value Pf of the materials weekly. When Pf≥0, trigger the transportation equipment to move the materials from the low-frequency area to the high-frequency area; otherwise, vice versa.

[0099] 2.4.2. Fragmented space integration:

[0100] Regularly check the fragmentation ratio of each storage location, for example, once a month. The fragmentation ratio of a storage location is the ratio of the remaining volume of the storage location to the total available volume of the warehouse, that is: the fragmentation ratio of storage location w is:

[0101]

[0102] If the fragmentation ratio of storage location w exceeds the threshold, dispatch the transportation equipment to reallocate the materials in the fragmented storage location, and the above-mentioned content can be used for the allocation method.

[0103] 2.4.3. Data query and operation log

[0104] 2.4.3.1. Real-time inventory query:

[0105] By scanning the RFID tag or querying the database, the storage location and quantity of the materials can be displayed in real time, as well as the dynamic changes of various inventories in the warehouse.

[0106] 2.4.3.2. Voice broadcast

[0107] Conduct voice broadcasts for the materials to be stored or retrieved and their storage location information.

[0108] 2.4.3.3. Operation log recording:

[0109] Record all operation information for warehousing, sorting, transportation, and storage, including time, materials, storage location, and execution equipment (such as the transportation equipment number).

[0110] 2.4.3.4. Report generation:

[0111] Turnover rate report: Analyze the material distribution in the high-frequency area and the low-frequency area;

[0112] Utilization rate report: Evaluate the use efficiency of the warehousing space and optimize the storage strategy.
