The tray is then placed in any empty shelf space displaying a blue light. The blue light location information for the tray is retrieved and linked to the QR code on the dial to generate material storage information, which is then stored in a pre-set storage system. Material production information is then obtained and automatically matched within the warehouse to generate a target material kit. This kit includes the target material's location, type, and quantity. The target material is then illuminated, making it easier for staff to find and retrieve the material. When staff retrieve the material, the target material information is matched against the production material information to determine if it was correctly retrieved. If an incorrect or abnormal removal is detected, the indicator light corresponding to the storage location of the target material will illuminate red, and an audible alarm will be triggered. After the alarm sounds, use a scanner to scan the shelf's QR code to silence the red light and audible alarm. Then, scan the shelf's QR code and the dial's QR code again, place the packaging tray back on the shelf, and restock any incorrectly removed trays. This reduces the difficulty and confusion of warehouse material management and improves material safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figure 1 This is a step-by-step process of a material in-and-out warehouse management method provided in an embodiment of the present application. DETAILED DESCRIPTION

[0055] The following combination Figure 1This application is further described in detail, but the embodiments of the present invention are not limited thereto.

[0056] The embodiment of the present application discloses a method for managing the entry and exit of materials.

[0057] In this embodiment, a material in-and-out management method includes:

[0058] S100: Use a scanner to obtain shelf QR code information on the shelf, obtain shelf vacancy information based on the shelf QR code information, and display a preset signal light blue according to the shelf vacancy information;

[0059] S200: Package the material in a packaging tray, use a scanner to obtain the dial QR code information on the packaging tray, place the packaging tray in a blue light vacant position on the shelf, and extract the blue light position information of the blue light vacant position;

[0060] S300: Bind the blue light location information with the dial QR code information, generate material storage information, and save the material storage information to a preset storage system;

[0061] S400: Obtain production material information, automatically identify the production material information and match it in the warehouse to obtain a target material kit, and send the target material kit to a staff member to pick up the target material;

[0062] S500: extracting target material information of the target material and determining whether the target material information is correct. If the target material information is determined to be incorrect, a red light is turned on at the target storage location corresponding to the target material and an audible alarm is sounded.

[0063] S600: After the alarm, use a scanner to scan the shelf QR code information, turn off the red light and sound alarm, and use a scanner to scan the shelf QR code information and the dial QR code information again, and put the target material back on the shelf.

[0064] It should be noted that the above process is only the basic steps of this embodiment. During the specific implementation process, some steps can be appropriately added, reduced or modified without affecting the overall implementation effect.

[0065] The steps for using a scanner to obtain the shelf QR code information on the shelf, obtaining the shelf vacancy information based on the shelf QR code information, and displaying the preset signal light blue according to the shelf vacancy information are as follows:

[0066] The shelf scans itself to obtain shelf storage information, and obtains shelf vacancy information based on the shelf storage information;

[0067] Upload shelf space information and update shelf QR code information in real time;

[0068] Use a scanner to obtain the shelf QR code information on the shelf and extract the shelf vacancy information from the shelf QR code information;

[0069] Based on the shelf vacancy information, the location data of each vacancy is obtained, and a lighting instruction is generated based on the location data. The lighting instruction is sent to the indicator light corresponding to each vacancy, and the indicator light is displayed blue.

[0070] In practice, for example, a manufacturing plant warehouse uses an automated material management system to manage material inbound and outbound inventory. When using a scanner to obtain the QR code information on a shelf, the shelf first uses its own scanning device to scan the entire shelf. In an actual operation, a warehouse manager used a scanner to scan the QR code on the shelf and obtain the shelf storage information. By analyzing this information, the system identified three vacancies on the shelf: A1, A2, and A3. The system uploaded this shelf vacancy information to a central database and updated the shelf QR code content in real time. Next, based on the identified shelf vacancy information, the system generated a lighting command and sent it to the corresponding indicator light for each vacant shelf. For example, the indicator lights for vacant shelves A1, A2, and A3 all lit blue, indicating that these locations were available for storage. Seeing the blue lights, the warehouse manager could quickly determine which locations were available, eliminating the need to manually search for vacancies, significantly improving work efficiency. To ensure the accuracy of this information, the system also automatically scans the shelves regularly to update shelf vacancy information. For example, after each material change, the system rescans the entire shelf to ensure the database is up to date with the latest vacancy information. During the entire process, the administrator only needs to use a scanner to scan the shelf QR code, and the system will automatically handle the subsequent steps without manual intervention.

[0071] Use a scanner to obtain the dial QR code information on the packaging tray, place the packaging tray in the empty blue light position on the shelf, and extract the blue light position information of the empty blue light position as follows:

[0072] Get the dial QR code information on the packaging tray and place the packaging tray in the blue light empty position on the shelf;

[0073] The blue light vacant position is used for packaging tray storage detection. When the blue light vacant position detects that a packaging tray is stored, the blue light of the blue light vacant position is turned off, and the blue light position information of the blue light vacant position is extracted.

[0074] In practice, for example, in a manufacturing plant's warehouse, during the incoming delivery of packaging trays, the warehouse manager uses a scanner to scan the QR code on the tray. For example, a tray with the QR code "M001" is labeled. After scanning, the manager obtains the corresponding material information for the tray: "Component M, Model M3, Quantity 500." The manager then places the tray in any empty space on the shelf with a blue light, such as space A1. Once the tray is placed in space A1, the sensor in that space detects that the tray has been stored and automatically turns off the blue light. The data transmission module then retrieves the blue light's location information, "A1-001." The system then records the tray's location and uploads it to the central database. For example, when the blue light in space A1 turns off, the system automatically records the association between the location information "A1-001" and the tray's QR code "M001." The manager does not need to manually record the location; the system automatically updates the data.

[0075] The steps for binding the blue light location information with the dial QR code information, generating material storage information, and saving the material storage information to the preset storage system are as follows:

[0076] Get the material information in the packaging tray and send it to the dial QR code information for integration;

[0077] Bind the blue light location information with the dial QR code information to generate material storage information;

[0078] Extract the shelf number of the shelf, save the material storage information to the preset storage system, and classify the material storage information according to shelf changes in the storage system to generate a material storage data set for each shelf;

[0079] Get the shelf QR code on the shelf, generate a data query port based on the shelf QR code, and connect the data query port with the corresponding material storage data set according to the shelf number.

[0080] In practice, for example, in a manufacturing plant's warehouse, during the material information binding process, the system first obtains material information from the packaging tray, such as "Component M, Model M3, Quantity 500." This information is transmitted via a scanner and merged with the QR code "M001" on the dial. The system then binds the blue light location information "A1-001" to the QR code "M001" on the dial, generating the complete material storage information "Component M-M3-500-A1-001." The system then extracts the shelf number "H001," saves the material storage information to a pre-defined storage system, and generates a material storage dataset based on shelf classification. For example, all material storage information for shelf H001 is consolidated into a single dataset. The system also generates a data query port based on the shelf QR code and connects it to the dataset. For example, by scanning the shelf QR code "H001-QR," an administrator can directly query information for all materials on shelf H001, eliminating the need for manual search.

[0081] The steps for obtaining production material information, automatically identifying the production material information and matching it in the warehouse to obtain the target material kit, and sending the target material kit to the staff to pick up the target material are as follows:

[0082] Obtain production material information, and obtain multiple material types and quantities that need to be prepared based on the production material information;

[0083] Match materials in the warehouse according to their type and determine the approximate storage location of each material;

[0084] Get the staff's location, and based on the staff's location and approximate storage location, get the pick-up time for each material;

[0085] Filter the approximate storage locations based on the pickup time and material quantity to obtain multiple target storage locations;

[0086] Aggregating multiple target storage locations to obtain a target storage location set, and fusing the target storage location set, material type, and material quantity to generate a target material kit;

[0087] Based on the target storage location set, the indicator lights on the shelves light up to prompt, and the target material kit is sent to the staff, who then pick up the goods according to the light prompts.

[0088] In practice, for example, in a manufacturing plant's warehouse, when the production department issues a material request, the system obtains production material information, such as "Component M, Model M3, Quantity 1,500; Component N, Model M3, Quantity 1,500." Based on the material type, the system matches storage locations within the warehouse, such as "Component M is stored in shelf H001-A1, and Component N is stored in shelf H002-B2." The system then obtains the staff's location, such as the administrator at the warehouse entrance (coordinates X1, Y1). Combining the administrator's location and the approximate storage locations of the materials, the system calculates the retrieval time for each material, such as "Component M takes 5 minutes to retrieve, and Component N takes 8 minutes to retrieve." Based on the retrieval time and material quantity, the system selects the target storage location, such as "Component M prioritizes shelf H001-A1, and Component N prioritizes shelf H002-B2." The system then combines the target storage location set with the material type and quantity to generate the target material kit: "Component M-M3-1500-H001-A1; Component N-M3-1500-H002-B2." The indicator lights corresponding to the target locations light up green, and the administrator quickly retrieves the materials according to the green light prompt.

[0089] The steps to screen the approximate storage location based on the pickup time and material quantity are as follows:

[0090] According to the retrieval time, multiple approximate storage locations are sorted in the first round to generate the first round of retrieval sequence;

[0091] Extract the entry time of each packaging tray in the approximate storage location, perform a second round of sorting on the approximate storage location according to the first-in-first-out rule based on the entry time, and generate the second round of retrieval sequence;

[0092] Based on the number of materials, the second round of picking sequence is screened to obtain the initial storage location of each material;

[0093] Extracting the location distance between each initial storage location and determining whether the location distance exceeds a preset distance threshold;

[0094] If it is determined that the location distance exceeds the distance threshold, the initial storage location exceeding the distance threshold is marked as a storage location to be replaced;

[0095] According to the first round of picking sequence, the storage position to be replaced is replaced to obtain a replacement storage position, and the replacement storage position and the initial storage position are combined to obtain multiple target storage positions.

[0096] In practice, taking a manufacturing plant's warehouse as an example, when selecting target storage locations, the system first sorts the approximate locations based on access time. For example, the approximate storage locations include "shelves H001-A1, H001-B2, and H002-C3," with access times of 5 minutes, 7 minutes, and 10 minutes, respectively. The system sorts these locations as "H001-A1 → H001-B2 → H002-C3." The system then extracts the entry time of each packaging tray, for example, "H001-A1 entered on June 1, 2023, H001-B2 on June 5, 2023, and H002-C3 on June 10, 2023." Following the first-in-first-out (FIFO) rule, the system re-sorts the locations as "H001-A1 → H001-B2 → H002-C3." Next, the second round of sequences is filtered based on the number of items. For example, if the number of items is 1500, the initial storage locations are "H001-A1 and H001-B2." Finally, the system calculates the distance between the initial storage locations. For example, if the distance between H001-A1 and H001-B2 is 3 meters, then if the preset distance threshold is 5 meters, no replacement is required. If the distance exceeds the threshold (e.g., 10 meters), the system replaces the item with a nearby location based on the first round of sequences.

[0097] The steps of extracting target material information of the target material and determining whether the target material information is correct, and if it is determined that the target material information is incorrect, lighting a red light at the target storage location corresponding to the target material and sounding an alarm, are specifically as follows:

[0098] Extract target material information of the target material, compare the target material information with the production material information, and obtain a comparison value;

[0099] Determine whether the comparison value exceeds the preset comparison threshold. If the comparison value is lower than the comparison threshold, the target material information is incorrect.

[0100] The indicator light of the target storage location corresponding to the target material turns red and an audible alarm sounds;

[0101] Monitor the packaging trays on the shelves, obtain the status data of the packaging trays, and determine whether there are any abnormalities in the packaging trays based on the status data;

[0102] If it is determined that the packaging tray is abnormal, the abnormal storage location corresponding to the packaging tray is extracted, the indicator light of the abnormal storage location is turned red and an alarm is sounded.

[0103] In practice, for example, in a manufacturing plant's warehouse, when a worker removes a target material, the system extracts the material information (e.g., "Component M, Model M3, Quantity 500") and compares it with the production material information (e.g., "Component M, Model M3, Quantity 1500"). If the match falls below a preset threshold (e.g., 90%), the target material information is determined to be incorrect. At this point, the indicator light at the target storage location (e.g., H001-A1) illuminates red, and an audible alarm is triggered. Simultaneously, the system monitors the status of packaging trays. If it detects a damaged tray, an obscured label, or unauthorized removal, it identifies an anomaly. The system then identifies the anomalous storage location (e.g., H002-B2), illuminates a red light, and issues an alarm. For example, during a particular removal, the system detects a quantity of 300 components M, less than the required 500. This information is determined to be incorrect, and a red alarm is issued for H001-A1. Simultaneously, another packaging tray is detected as being removed without authorization, and a red alarm is issued for H002-B2.

[0104] Use a scanner to scan the QR code on the shelf, turn off the red light and sound alarm, and use the scanner to scan the QR code on the shelf and the dial again. Place the target material back on the shelf. The specific steps are as follows:

[0105] Use a scanner to scan the shelf QR code information. The scanner generates a manual operation signal based on the shelf QR code information and sends the manual operation signal to the shelf;

[0106] After receiving the manual operation signal, the shelf will turn off the red light and sound alarm;

[0107] Use a scanner to scan the QR code information on the shelf for a second time, and the shelf will light up blue lights for each empty space according to the shelf vacancy information;

[0108] Use a scanner to scan the QR code on the dial and send it to the shelf through the scanner;

[0109] The staff will place the packaging tray with abnormality or incorrect target material information on the target empty position with a blue light;

[0110] The shelf extracts the vacant position data of the target space, binds the vacant position data with the dial QR code information, generates updated material storage information, and updates the data in the storage system according to the updated material storage information.

[0111] In practice, for example, in a manufacturing plant's warehouse, when a red light alarm sounds, the administrator uses a scanner to scan the shelf's QR code "H001-QR." The system generates a manual operation signal and sends it to the shelf. Upon receiving the signal, the shelf turns off the red light and audible alarm. The administrator then scans the shelf's QR code a second time, and the blue lights of all empty slots reappear. The administrator then scans the QR code "M001" on the dial of the abnormal packaging tray and sends it to the shelf. For example, if a packaging tray is returned due to an incorrect quantity, the administrator places it in the empty blue-lit slot A3. The shelf extracts the empty slot "A3-001," binds it to the QR code "M001," generates updated material storage information "Component M-M3-300-A3-001," and updates the storage system data.

[0112] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
