[0003] Currently, electronic tags improve the convenience of picking in the logistics picking field, but they cannot accurately prevent errors. Therefore, gratings are installed on shelves or sorting walls to sense whether the inbound and outbound actions are correct. However, multiple grating sensors are needed, which is costly and leads to redundant internal wiring. Summary of the Invention

[0014] The left endpoint coordinate is deviated to the left by a preset range, and the right endpoint coordinate is deviated to the right by the preset range to obtain the left endpoint and right endpoint of the storage.

[0015] The sorting work area is divided according to the left end point and the right end point of the storage to obtain the storage frame area.

[0020] Obtain the location of the sorting action within the sorting work area;

[0021] The storage box area corresponding to the sorting action is determined based on the coordinates of the landing point and the storage box area information.

[0022] The storage box area corresponding to the sorting action is compared with the storage box area corresponding to the goods to be sorted. If the storage box area corresponding to the sorting action is inconsistent with the storage box area corresponding to the goods to be sorted, an alarm is triggered.

[0023] The alarm includes changing the color of the electronic tag.

[0024] Preferred options also include:

[0025] Confirm the storage box area to be picked up based on the storage box area corresponding to the replenished goods to be sorted;

[0026] A pickup instruction is generated based on the storage box area to be picked up;

[0048] The present invention will be further explained below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0051] The cargo sorting method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0052] This application provides a method for sorting goods. Figure 1 This is a flowchart of a goods sorting method in one embodiment. Figure 1As shown, a goods sorting method includes the following steps:

[0053] Step S101: Divide the sorting work area into multiple different storage box areas according to the parameter information of the storage box.

[0054] Specifically, the parameters of the storage box can include the length of the storage box, that is, the length of the storage box in the horizontal direction.

[0055] Since the goods will ultimately be placed in the storage boxes, and the storage boxes may not be placed evenly and neatly, the horizontal area may not be distributed proportionally, or each storage box may not be the same size and width, and each storage box occupies a different width position, or storage boxes of different sizes and widths may be replaced with storage boxes of different spacing, the work surface is divided according to the width coordinates of the actual storage boxes when dividing the area. This is more accurate and can adapt to different placement positions and storage boxes of different sizes.

[0056] Figure 2 This is a schematic diagram illustrating the division of the storage box area in one embodiment. For example... Figure 2 As shown, taking storage boxes 1 and 2 as examples, the sensing range of the storage boxes varies depending on their horizontal length. The length of the sensing range is the original length of the storage box plus a preset length, and the horizontal length of the sensing range is the width of the storage box area.

[0057] Step S102: Use lidar to acquire the sorting actions of sorting personnel in the sorting work area.

[0058] It should be noted that the lidar can accurately sense each storage compartment area, and can detect when an operator reaches into any storage compartment area.

[0059] LiDAR can be used to monitor and provide feedback on the sorting actions of personnel in the work area in real time. Such monitoring helps managers understand the work status, efficiency, and accuracy of sorting personnel, and promptly identify and correct problems.

[0060] Step S103: Determine the storage box area corresponding to the sorting action, and determine whether the storage box area corresponding to the sorting action is consistent with the storage box area corresponding to the goods to be sorted. If the storage box area corresponding to the sorting action is inconsistent with the storage box area corresponding to the goods to be sorted, an alarm will be triggered.

[0061] Sorting personnel categorize items into different classes or groups according to pre-set rules and requirements, and assign corresponding storage bin areas for replenishment. Typically, goods are categorized based on orders. If the storage bin area corresponding to a sorting action does not match the storage bin area corresponding to the goods to be sorted, an audible and visual warning will be issued.

[0062] This application divides the sorting work area using the parameter information of the storage boxes, and then determines whether the sorting action falls within the storage box area where goods should be sorted according to preset rules based on the sorting action identified by LiDAR, and issues an alarm based on the judgment result. Furthermore, it can adapt to different placement positions and storage boxes of different sizes. Therefore, this invention utilizes the parameter information of LiDAR and storage boxes to divide the sorting work area and verify the correctness of the sorting action results, and will also issue an alarm when the verification result is incorrect.

[0063] Figure 3 This is a schematic diagram illustrating the principle of lidar area division in one embodiment. For example... Figure 3 As shown, in one embodiment, a coordinate system is established on the replenishment operation interface of the sorting and sorting wall covered by lidar as the sorting work area, and the sorting work area is divided into 12 storage box areas, each corresponding to the location of a storage box. During outbound or inbound operations, the lidar captures the operator's actions, such as reaching out, to determine the storage box area corresponding to the operator's current operating area. If the storage box area corresponding to the current operating area matches the one assigned by the system, the operation is correct; if the storage box area corresponding to the current operating area does not match the one assigned by the system, an alarm is triggered.

[0064] In a feasible practical example, before dividing the sorting work area into multiple different storage box areas based on the parameter information of the storage boxes, the following steps are included:

[0065] Use LiDAR to scan the sorting wall to obtain the replenishment operation area;

[0066] It should be noted that in this embodiment, only one lidar is installed. The lidar is located at the top corner of the shelf or sorting and seeding wall, with a rectangular working surface and a detection angle of 90°. The lidar can cover the entire replenishment operation surface.

[0067] Establish a Cartesian coordinate system based on the replenishment operation surface, and obtain the sorting work area based on the Cartesian coordinate system.

[0068] Specifically, with the lidar as the origin, two straight lines on the replenishment operation surface (such as the edge of the operation surface or the shelf) can be selected as two axes to establish a rectangular coordinate system.

[0069] Furthermore, based on the shape of the sorting area on the replenishment operation surface, its boundaries are determined by measurement or according to the dimensions in the design drawings. In a Cartesian coordinate system, the position of each point can be represented by a coordinate pair (x, y), where x and y represent the horizontal and vertical positions of the point on the replenishment operation surface, respectively.

[0070] By establishing a Cartesian coordinate system, the storage bins in the sorting work area can be positioned more accurately, and it can also help replenishment personnel quickly locate the storage bins to be replenished, thereby improving replenishment efficiency.

[0071] In a feasible practical example, the sorting work area is divided into multiple different storage box areas based on the parameter information of the storage boxes, including:

[0072] Obtain the horizontal coordinates of the storage box, and get the coordinates of the left and right endpoints.

[0073] The sorting area is divided according to the left and right ends of the storage area to obtain the storage box area.

[0074] Specifically, the positions of the right and left edges of the storage box are measured or recorded using LiDAR, and the coordinates of the right and left edges of the storage box are determined in a Cartesian coordinate system. This ensures the accuracy and usability of the acquired coordinate data.

[0075] Based on the measured coordinates, the coordinates of the left and right endpoints of the storage box are obtained. The left endpoint coordinates refer to the coordinates of the left edge of the storage box, and the right endpoint coordinates refer to the coordinates of the right edge of the storage box.

[0076] The left endpoint coordinates are shifted to the left by a preset range, and the right endpoint coordinates are shifted to the right by a preset range, to obtain the left and right endpoints of the storage.

[0077] For example, in this embodiment, the length of the first layer of the sorting and seeding wall is 350cm, and the length of the storage box is 70cm. When the storage box is returned from the back to the working surface, its horizontal length segment is read as (5, 75), the second storage box as (80, 150), the third storage box as (165, 235), the fourth as (250, 320), and so on. Finally, it can be ±2~5 cm at each coordinate, which can improve the error tolerance. Figure 4This is a schematic diagram of the horizontal endpoints of the storage boxes in one embodiment, where A is the left endpoint of storage box 1, B is the right endpoint of storage box 1, C is the left endpoint of storage box 2, D is the right endpoint of storage box 2, E is the left endpoint of storage box 3, F is the right endpoint of storage box 3, G is the left endpoint of storage box 4, H is the right endpoint of storage box 4, a is the left endpoint of storage box 1 area, b is the right endpoint of storage box 1 area, c is the left endpoint of storage box 2 area, d is the right endpoint of storage box 2 area, e is the left endpoint of storage box 3 area, f is the right endpoint of storage box 3 area, g is the left endpoint of storage box 4 area, and h is the right endpoint of storage box 4 area. Figure 4 As shown, the horizontal coordinates of the storage boxes are as follows: A = 5, B = 75, C = 80, D = 150, E = 165, F = 235, G = 250, and H = 320. With a preset range of 3, the corresponding horizontal coordinates of the storage box areas are: a = 2, b = 78, c = 77, d = 153, e = 162, f = 237, g = 247, and h = 323.

[0078] In a feasible practical example, the sorting wall has multiple sets of electronic tags. These sets include tags for the replenishment operation area and tags for the picking operation area. The tags for the replenishment operation area are used to display replenishment information and alarms associated with the storage compartment area. The tags for the picking operation area are used to set reminders and alarms.

[0079] Specifically, the electronic tags on the replenishment operation panel can be five-digit tags to display order codes. Replenishment personnel can use these order codes to further confirm whether the storage compartments awaiting replenishment meet the requirements. The electronic tags on the retrieval operation panel can be single-light tags, providing alerts and alarms through illumination. Since single-light tags are relatively inexpensive compared to other electronic tags, this also reduces costs.

[0080] After dividing the sorting area according to the left and right endpoints of the storage, resulting in the storage box area, it includes:

[0081] The storage compartment area is associated with the electronic tag group one-to-one, so that the storage compartment area and the electronic tag group correspond one-to-one.

[0082] Specifically, assign a unique identification number or name to each storage compartment area. This can be numbers, letters, or other recognizable identifiers. Ensure that each storage compartment area has a unique identifier.

[0083] Next, assign a unique identifier number or name to each electronic tag group. These identifiers can be set on each electronic tag group either programmatically or manually. Establish a one-to-one association between the identifiers of the storage compartment areas and the identifiers of the electronic tag groups. This relationship can be represented using a set or matrix to ensure that each storage compartment area corresponds to a specific electronic tag group.

[0084] Figure 5 This is a structural diagram of the front of a sorting and seeding wall in one embodiment. The front is the replenishment operation surface. Figure 5 As shown, the front of the sorting and seeding wall is equipped with electronic tags, storage boxes, touch screens, and lidar.

[0085] Replenishment personnel can log in to the touchscreen system using facial recognition, fingerprints, ID cards, usernames, or other information to view order information that needs replenishment.

[0086] Based on the order information, the corresponding goods in the order are placed into the designated storage boxes in sequence. LiDAR is used to detect whether the storage box area where the goods are placed is the designated area for replenishment. If it is not the designated area for replenishment, an alarm is triggered.

[0087] After all the goods are placed in the corresponding storage boxes, touch the electronic tag button to complete the goods receiving operation for that order.

[0088] Figure 6 This is an example illustration of sorting action area determination in one embodiment, where the hand icon represents the sorting action, light-colored squares represent storage box areas awaiting replenishment, and dark-colored squares represent storage box areas not awaiting replenishment. Figure 6 As shown, in a feasible practical example, the storage box area corresponding to the sorting action is determined, and it is determined whether the storage box area corresponding to the sorting action is consistent with the storage box area corresponding to the goods to be sorted. If the storage box area corresponding to the sorting action is inconsistent with the storage box area corresponding to the goods to be sorted, an alarm is triggered, including:

[0089] Obtain the location of the sorting action within the sorting work area.

[0090] Specifically, when sorting personnel perform sorting actions, LiDAR can scan and capture the position of objects. By analyzing and processing the data on the location of these actions, data on the sorting status of objects at different locations within the sorting work area can be obtained. This can be used to optimize the sorting process and improve item placement strategies.

[0091] The storage box area corresponding to the sorting action is determined based on the coordinates of the landing point and the storage box area information.

[0092] Algorithms such as distance calculation and boundary determination can be used to determine whether the landing point is within the storage box area. When a match is successful, the identifier number or name of the storage box area corresponding to the landing point is determined. This information is then associated with the sorting action, indicating the storage box area corresponding to the sorting action.

[0093] The system compares the storage box area corresponding to the sorting action with the storage box area corresponding to the goods to be sorted. If the storage box area corresponding to the sorting action is inconsistent with the storage box area corresponding to the goods to be sorted, an alarm is triggered.

[0094] Once an alarm is triggered, the system should take appropriate measures, such as issuing an audible alarm, sending an alarm notification to relevant personnel, or logging the information. This will draw the attention of staff and allow for timely handling of any inconsistencies.

[0095] The alarm includes changing the color of the electronic tag.

[0096] The electronic tags for each storage compartment area can be configured with the ability to change color. This could be LEDs with multiple colors, or an LCD screen displaying different colors. Depending on specific needs and system capabilities, the electronic tag color can be changed to red, flashing, or other eye-catching colors to attract staff attention.

[0097] In a feasible practical example, it also includes:

[0098] The storage area to be picked up is determined based on the storage area corresponding to the replenished goods to be sorted.

[0099] Specifically, after restocking is completed, you can confirm that the restocking is complete by touching the button or electronic tag on the restocking operation panel.

[0100] Generate a pickup instruction based on the storage area to be picked up.

[0101] Based on the actual scenario and needs, determine the specific details of the pickup instruction. This may include information such as the name, quantity, batch, and target location of the goods. Inform the operators of the storage area where the goods are to be picked up so they can accurately retrieve the goods that need to be sorted.

[0102] The electronic tag on the pickup operation surface will light up to indicate the pickup order.

[0103] The pending pickup instruction includes the storage compartment area, goods information, and other necessary related instructions. This can be obtained through the system's order management or inventory management module. Upon receiving the control instruction, the device or system controlling the electronic tags in the storage compartment area will illuminate the corresponding electronic tag based on the instruction content. The electronic tags can be illuminated, flashed, or have their status changed according to specific requirements to remind the operator to perform the pickup operation.

[0104] Figure 7 This is a schematic diagram of the back structure of the sorting and seeding wall in one embodiment. The back side is the surface where goods are picked up. Figure 7 As shown, the back is equipped with a LiDAR scanner, a single-lamp electronic tag, and a storage compartment. The combination of the LiDAR scanner and the single-lamp electronic tag can be used to confirm outbound shipments, update storage compartment areas, indicate which storage compartment is awaiting pickup, and verify the correctness of the pickup.

[0105] In a feasible practical example, after controlling the electronic tag on the pickup operation surface to light up in response to the pickup instruction, the process also includes:

[0106] Receive the pickup confirmation message from the electronic tag on the pickup operation panel.

[0107] Specifically, the electronic tag can be a single-light electronic tag. Operators can send a pickup instruction by touching the electronic tag. A pickup instruction can also be sent when the replenishment interval exceeds a preset time or when the replenishment quantity is exceeded.

[0108] Use LiDAR to rescan the storage area to be picked up to see if there are any storage boxes. If storage boxes are found in the area, update the storage area.

[0109] Specifically, a lidar device is used to scan the storage area where the item is to be retrieved. The lidar emits a laser beam and measures the reflected laser signal to obtain information about the position and shape of objects in that area.

[0110] In one feasible embodiment, each of the pickup and replenishment operation surfaces has a lidar for monitoring the operation and changes of the storage box area on the corresponding surface.

[0111] When the pickup operation interface updates the storage box area, the updated storage box area will also be synchronized to the replenishment operation interface.

[0112] In a feasible practical example, after receiving the pickup instruction output by the electronic tag on the pickup operation surface, the process further includes obtaining the pickuped storage box area through LiDAR and determining whether the pickuped storage box area is consistent with the pending pickup storage box area associated with the electronic tag.

[0113] An alarm will be triggered if the area of ​​the storage box where the item has already been picked up does not match the area of ​​the storage box to be picked up that is associated with the electronic tag.

[0114] In a feasible practical example, using lidar to acquire information about the sorting actions of replenishment personnel in the sorting work area before:

[0115] Obtain orders to be sorted.

[0116] Specifically, upon receiving order information, the order content is parsed and the necessary information is extracted. Based on the order format and field definitions, the system ensures that the relevant data in the order is correctly parsed and extracted.

[0117] Determine the storage boxes to be replenished based on the orders to be sorted.

[0118] It's important to note that identifying storage boxes to be replenished requires checking the current storage box inventory, including the quantity, location, and status of the boxes. Ensure there are sufficient storage boxes available for replenishment and know the location of each box for subsequent operations.
