Hereinafter, a warehouse management system according to a preferred embodiment of the present invention will be described with reference to the drawings.

1 is a view for explaining a warehouse management system according to an embodiment of the present invention.

Referring to FIG. 1, the warehouse management system includes a plurality of products BX to which product information tags T1, T2, and T3 (see FIG. 3) are attached to provide product related information; The product information tags T1, T2, and T3 attached to the corresponding product BX are transferred to the predetermined scan points A, B, and C corresponding to the plurality of products BX, A flight body 100 for recognizing the vehicle; And a control system for resetting the scan point of the flying object by comparing the recognition information transmitted from the air vehicle 100 with the previously stored management information through a scan operation. And a shelf 200 of a predetermined size, which is disposed in the warehouse and on which the plurality of goods BX are loaded.

First, a plurality of products BX are seated with various products therein, and the outside may be formed of a packaging member, for example, in the form of a box for protecting the product. The product information tag which can refer to the distribution information of the product may be attached to a plurality of the goods BX in the form of a barcode or an electronic tag.

Next, the flight body 100 can be configured as a free flight capable of flying according to a command of a control system controlled by an administrator, for example, as a dragon. Drones are basically capable of flying, and can be equipped to perform various operations.

Particularly, the air vehicle 100 is equipped with a recognition device such as a scanning device and a receiving device for recognizing the product information tag and providing the product information tag to the control system, and measures the spatial distance based on the position of the air vehicle 100 and provides the measured distance to the control system A distance measuring device 110 such as a distance measuring sensor is mounted. Here, the space distance means the distance between the flying object 100 and the wall, the flying object 100, and the shelf 200, and is used to generate a position change operation or a layout of a warehouse to reset a scan point to be described later.

Next, a control system (not shown) controls the flight operation of the air vehicle 100 and a scan operation for recognizing the product information tag. Then, a database for managing a plurality of products BX is generated through the information recognized by the air vehicle 100.

Hereinafter, for convenience of explanation, information corresponding to a plurality of goods BX to be delivered from the air vehicle 100 to the control system is referred to as " recognition information ", and information corresponding to a plurality of goods BX Information will be referred to as " management information ". For example, when information corresponding to the first-arrived goods item BX is provided directly to the control system by the goods receipt list or the manager, this corresponds to the management information, and information corresponding to the first-arrived water article (BX) (100), it corresponds to the recognition information.

The control system according to the embodiment of the present invention can reset the scan point of the air vehicle 100 by comparing the recognition information with the previously stored management information. This will be described in more detail with reference to FIG.

2 is a view for explaining the control operation of the control system according to the embodiment of the present invention.

2 shows a side view of a shelf 200 on which a plurality of products BX are stacked and three products A 1, A 2 and A 3 are stacked on the top of the shelf 200, B2 and B3 are stacked in the center of the shelf 200 and two products C1 and C2 are stacked at the bottom of the shelf 200. [

The product information tag is attached to each of the distribution products A1, A2, A3, B1, B2, B3, C1, and C2 to provide product- It is possible to recognize the corresponding product information tag through wireless communication at a certain interval with the tag.

The air vehicle 100 must be positioned at the first scan point A in order to recognize the three goods products A1, A2 and A3 stacked on the top and the three goods products B1, B2 and B3 And must be located at the third scan point C in order to recognize the two goods products C1 and C2 loaded at the lowermost part. The coordinates of the first to third scan points A, B and C are stored in the control system. The control system controls the first to third scan points A, B and C to recognize the corresponding product, So that the air vehicle 100 can be positioned.

However, the air vehicle 100 may not be positioned at a predetermined scan point due to an unwanted operation error or a mechanical defect of the air vehicle 100. [ At this time, the control system according to the embodiment of the present invention can detect the flying object so as to reset the scan point of the flying object 100 and control the flying object 100 to be located at a scan point at which scanning can be performed.

More specifically, the warehouse management system according to the embodiment of the present invention checks the quantity of the received goods BX, stores the information as management information, and loads the goods BX. Moving the air vehicle (100) to a position corresponding to a predetermined scan point of the product (BX); Generating identification information by recognizing a product information tag attached to the product (BX) through a scan operation of the air vehicle (100); And resetting the scan point of the flying object by comparing the management information and the recognition information. The warehouse management system according to an embodiment of the present invention further includes updating the management information with the rewritten identification information after the resetting step.

First, when the goods arrive at the warehouse, the quantity of the goods is checked and stored as management information. That is, the management information indicates that the three distribution products A1, A2, and A3 are loaded at the top of the shelf 200 and that three distribution products B1, B2, and B3 are loaded at the center of the shelf 200 And two items of goods (C1, C2) are loaded at the bottom of the shelf (200).

The manager then manages the eight logistics products A1, A2, A3, B1, B2, B3, C1, C2 loaded using the air vehicle 100. [ At this time, the manager places the air vehicle 100 at the first scan point A, and the air vehicle 100 recognizes the three goods products A1, A2, and A3 on the upper part of the shelf 200, do. Thereafter, the air vehicle 100 is positioned at the second scan point B and the third scan point C to perform the recognition operation.

When the air vehicle 100 is accurately positioned at the first, second, and third scan points A, B, and C, the air vehicle 100 has three distribution products A1, A2, and A3 at the top of the shelf 200 And the recognition information that the two distribution products (B1, B2, B3) are loaded in the center of the shelf (200) and the two distribution products (C1, C2) And the control system compares the previously stored management information with the recognition information to verify whether or not the logistics product is missing.

However, if the air vehicle 100 is not located at the first to third scan points A, B, and C due to a malfunction due to a false error or a mechanical defect, particularly an error of the distance measuring device 110, And delivers the information of the quantity of goods to the recognition information. At this time, the control system recognizes that the previously stored management information is different from the recognition information, and it is possible to reset the scan point so that the air vehicle 100 can be relocated to the first to third scan points A, B, and C.

The resetting operation is performed by freely flying a predetermined range on the basis of the current space distance information provided by the flying body 100. The flying body 100 continuously scans the goods BX during free flight to obtain recognition information To the control system. Then, the control system continuously compares the recognition information and the management information and performs a reset operation until matching is achieved. The fact that the recognition information and the management information match each other means that the flight body 100 is positioned at a desired scan point and this means that it is possible to accurately recognize the quantity of the goods BX on which the flight body 100 is loaded do.

The warehouse management system according to the embodiment of the present invention compares recognition information with management information to recognize that the flight body 100 is out of a predetermined scan point and in this case, 100) is located at the original scan point.

On the other hand, assuming that there is no error in the distance measuring apparatus 110 mounted on the air vehicle 100 and that the goods BX are always in a predetermined position under ideal operating conditions, the first to third scan points A, B, and C do not change. However, when undesired spatial changes or positional changes occur in the product due to a distortion of the packaging member due to a process mistake or water leakage, or an earthquake, the first to third scan points A, B, and C must be changed.

In this case, it is also possible for the control system to reset the existing scan point to another scan point through the reset operation of the air vehicle 100. [ The control system sets the current spatial information of the air vehicle 100 as a new final scan point when the re-created recognition information matches the management information at the reset scan point. Therefore, if the quantity is to be checked again for the management of the goods BX, the control system can control the vehicle 100 to be positioned at the newly set final scan point.

The warehouse management system according to the embodiment of the present invention resets the scan position of the air vehicle 100 by comparing the management information stored in the control system with the recognition information acquired from the air vehicle 100, It is possible to increase the reliability of the management information stored in the control system.

For reference, the goods to be loaded in the warehouse may have different sizes and shapes, which may vary depending on the size and shape of the goods to be loaded in the first to third scan positions A, B, and C it means. Therefore, in the warehouse management system according to the embodiment of the present invention, it is possible to continuously update the scan point optimally through the reset operation of the air vehicle 100 in order to increase the recognition rate for the goods not loaded according to the standard.

On the other hand, the management information may be erroneous due to the administrator's error. At this time, the manager can reset the scan point and then transmit the re-created recognition information to the control system to update the management information.

FIG. 3 and FIG. 4 are views for explaining the operation of creating the warehouse layout diagram using the air vehicle 100 of FIG.

Referring to FIG. 3, a plurality of shelves 200 for loading a plurality of products are provided in the warehouse. For example, three warehouses B1, B2, and B3 are disposed in the center of the shelf 200 as an example. As already described above, the product information tags T1, T2, and T3 for providing product related information are attached to each of the three distribution products B1, B2, and B3.

On the other hand, a shelf information tag (XYZ) is attached to the shelf (200). The shelf information tag XYZ provides all information corresponding to the shelf 200 and the information provided herein may be the date, material, weight, size, orientation, etc., of the shelf 200, 200 includes information such as a length, a length, and a height. Here, the shelf 200 has an external shape of a hexagonal column having a width (CX), a length (CY), and a height (CZ). However, the shape of the shelf 200 can be designed in various shapes for loading the goods BX, and the shelf information tag XYZ can include information corresponding to its external size.

The air vehicle 100 according to the embodiment of the present invention can detect the size and arrangement direction of the shelf 200 by recognizing the shelf information tag XYZ and it is possible to generate the distribution warehouse layout diagram through this. Hereinafter, a method of generating the layout of the warehouse using the flight object 100 and the shelf information tag XYZ will be described with reference to FIG.

FIG. 4 illustrates a plan view P of the warehouse and FIG. 4 illustrates an example in which the first to third shelves 200A, 200B, and 200C are disposed in the warehouse. The first shelf 200A is disposed on the lower left side with respect to the plan view P while the second shelf 200B is disposed on the upper left side with respect to the plan view P and the third shelf 200C is disposed on the upper left side with respect to the plan view P ) On the right side.

Here, the horizontal and vertical sizes of the first shelf 200A and the horizontal and vertical sizes of the second shelf 200B are the same as one example, and the size of the third shelf 300C on the plane is As an example. The first shelf 200A is attached with a shelf information tag XYZ corresponding to the first shelf 200A on the upper left portion of the plane and the second shelf 200B is attached to the second shelf 200A The shelf information tag XYZ corresponding to the third shelf 200C is attached to the lower left portion and the upper portion on the plane of the third shelf 200C do.

On the other hand, the layout of the warehouse is substantially created in the control system by the space distance information provided by the air vehicle 100 and the size information of the shelf, and the administrator can control the air vehicle 100 based on the layout of the warehouse, And control of the goods BX can be performed.

Subsequently, the layout of the warehouse is generated in the order of (1) -> (2) -> (3), and the actual position of the air vehicle 100 in the control system may be represented by "D". For reference, the outer walls of the warehouse are shown in (1), (2), and (3). However, when the layout of the first to third shelves 200A, 200B, The outer walls of the first and second shelves 200A, 200B, and 200C can be formed along with the flight path of the air vehicle 100 together with the first, second, and third shelves 200A, 200B, and 200C.

For reference, in the case of the distance measuring apparatus 110 mounted on the air vehicle 100, the measurement distance is limited. In FIG. 4, the limited measurement distance is shown by a dotted circle with reference to the flight "100", "D". The measurement of the circle of the dotted line in the air vehicle 100 means that the distance measurement device for measuring the spatial distance to the side surface of the air vehicle 100 is mounted.

First, when the air vehicle 100 enters the operation mode for generating the layout of the warehouse, the air vehicle 100 provides its control unit with the current spatial distance information. Here, the space distance information means the distance between the air vehicle 100 and the wall, and the distance between the air vehicle 100 and the shelf 200. Accordingly, the air vehicle 100 scans the range of the circle of the dotted line to provide the spatial distance information to the control system, and the control system is able to generate the warehouse layout diagram like (1).

Next, the air vehicle 100 moves in the direction in which the opened passage is formed, continuously provides its spatial distance information to the control system, and continuously generates the layout of the warehouse through the control system. For reference, when the shelf information tag XYZ is not included in the range that the air vehicle 100 can scan, the control system generates the layout map using only the space distance information of the air vehicle 100, The shelf 200 can not be distinguished.

Next, when the shelf information tag XYZ is included within the range that the air vehicle 100 can scan, the air vehicle 100 recognizes the shelf information tag XYZ and provides the shelf related information to the control system. Here, the shelf-related information provided may include the size and arrangement direction of the shelf, the size of the shelf means the width, the length, the height, etc., and the arrangement direction is the width direction it means. Therefore, the control system can estimate the arrangement of the first shelf 200A on the basis of the shelf information tag XYZ, through which the first shelf 200A is shown as (2) in the layout of the warehouse It is possible.

For reference, the control system recognizes the shelf information tag XYZ of the first shelf 200A while the first shelf 200A is out of the spatial distance scanned by the air vehicle 100, as shown in (2) It is possible to create a warehouse layout chart that is shown so that one shelf 200A is completely included. At this time, since the shelf information tag XYZ corresponding to the second shelf 200B is not yet recognized, it can be seen that only a part of the second shelf 200B is shown in (2).

Next, the air vehicle 100 continues to move in the direction in which the opened path is formed, recognizes the shelf information tag XYZ of the second shelf 200B, and recognizes the shelf information tag XYZ of the third shelf 200C To the control system. Accordingly, it is possible for the control system to show the second shelf 200B and the third shelf 200C as (3) on the layout of the warehouse based on the provided shelf information tag XYZ.

The third shelf 200C has a plurality of shelf information tags XYZ attached thereto in order to more accurately recognize the placement direction of the third shelf 200C and to detect the direction of placement of the third shelf 200C, ) Of the shelf information tag (XYZ) in a stochastic manner.

For reference, if the positioning direction is more accurately recognized, if the two shelf information tags XYZ are included in the scanning range of the flying object 100, the control system controls the arrangement direction of the shelves through the two shelf information tags XYZ, It means that the size is more accurately recognized and the layout is generated. Of course, it is also possible to recognize the placement direction and size of the shelf through the information provided in one shelf information tag XYZ, but if the control system is provided with a plurality of shelf information tags XYZ attached to the shelf outline The control system will be able to more accurately recognize the outline of the shelf so as to generate the layout plan.

In the case of the third shelf 200C, the flight vehicle 100 selects the upper route and the lower route in the case of the third shelf 200C. If the shelf information tag XYZ is attached to both sides of the flight path of the air vehicle 100 like the third shelf 200C, even if the air vehicle 100 selects a route, (200C) can be recognized.

The warehouse management system of the present invention can accurately and quickly create the distribution warehouse layout diagram through the air vehicle 100, and it is possible to set the flight path of the air vehicle 100 more smoothly through it. The smooth flight path setting of the air vehicle 100 means that the flight time of the air vehicle 100 can be shortened and the collision can be prevented.

In FIG. 4, the layout map of the warehouse is generated using the length and length of the shelf information tag XYZ, but it is also possible to generate the three-dimensional layout map by receiving the height information.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but rather are not intended to limit the scope of the technical idea of the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
