[0024] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In the process of describing the present invention, for the convenience of overall understanding, the same reference numerals are used for the same structural elements in the drawings, and the repeated description of the same structural elements is omitted.

[0025] Figure 1 This is a conceptual diagram for explaining a merchandise picking assistance method based on a proximity sensor according to an embodiment of the present invention.

[0026] Referring to Figure 1 , according to an embodiment of the present invention, a user may be located in an area where multiple merchandise are displayed or a specific area. A cart loaded with at least one picking box may move to the specific area where the user is located in consideration of the merchandise to be picked. The user may pick the merchandise to be picked (picking) into the picking box of the cart that has moved to the area where the user is located. And when the user picks all the pickable merchandise in the area where the user is located into at least one picking box of the corresponding cart through the user's own user terminal, picking completion information may be input. Based on this, the cart may move to the area of other users to pick the next merchandise.

[0027] Among them, a picking box may also be expressed as a basket or a box, and multiple picking boxes may be loaded or carried on the cart and moved together. Among them, the cart may include a communication module, a processing module, and a driving module, and may mean a device or unit that can move at least one picking box at a time. Referring to Figure 1 , for example, the cart may be represented as a quadrilateral formed by dotted lines. However, the cart may vary according to the embodiment. For example, as shown in Figure 2 described later, when the cart moves through a track, the cart may not include an additional driving module. Regarding this, it will be described in detail together with Figure 2 .

[0028] In other words, in one embodiment, multiple picking boxes may move together through the cart, which may be more effective when picking a large number of merchandise at one time according to multiple picking merchandise lists.

[0029] For example, in one embodiment, in order to move to the area where the merchandise to be picked is displayed or the user in the corresponding area, the current merchandise to be picked may be derived from the picking object list. Based on the information of the current merchandise to be picked, the area information where the current merchandise to be picked is displayed may be obtained. Among them, the information related to the current merchandise to be picked may include at least one of the merchandise name of the current merchandise to be picked, the area information of the display, the display position information, the total quantity information that needs to be picked into the picking box, the information related to the picking box that needs to pick the current merchandise to be picked in the picking box, and the quantity information of the current merchandise to be picked that each picking box needs. In one embodiment, based on this, not only can the cart be moved to the display area, but also the above information can be provided to the user terminal to assist the user in appropriately performing the picking work on the moving cart.

[0030] That is, according to one embodiment, a trolley including a plurality of picking bins can be moved to the area where the target picking item is displayed based on the area information of the target picking item, and the user can perform the picking work on the plurality of picking bins based on the information of the target picking item provided by the user terminal. After that, according to one embodiment, the user can input the picking completion information through the user terminal. In one embodiment, when the picking completion information is received, the trolley including the plurality of picking bins can be moved to the area where the next target picking item is displayed to perform the next picking work. That is, the next target picking item can be derived from the picking target list, and based on the information of the next target picking item, the trolley can be moved to the area where the next target picking item is displayed.

[0031] Among them, in one embodiment of the present invention, it can be derived that the trolley arrives at the area where the target picking item is displayed based on the proximity sensor, and the movement of the trolley can be stopped based on this. This will be described in more detail as follows.

[0032] For example, according to one embodiment, the trolley can select the area where the current target picking item is displayed or the user terminal located in that area. For example, when the trolley moves to that area and stops based on the distance from the user terminal, the user terminal can be selected. When it moves to that area and stops based on the distance from other reference objects or reference terminals in the corresponding area, the area (i.e., the reference terminal located in that area) can be selected.

[0033] After that, the trolley can move towards the reference terminal or the user terminal of the selected area and stop when it reaches within a specified distance from the reference terminal or the user terminal. That is, when the distance between the reference terminal or the user terminal and the trolley is within the specified distance, it can be determined that the corresponding area has been reached, and thus the movement of the trolley can be stopped.

[0034] Among them, the distance can be derived based on the proximity sensor and it can be determined whether it is within the specified distance. Or for example, the distance can be derived based on the proximity sensor of location based services (LBS).

[0035] A user located in a specific area can pick the target picking item displayed in the specific area into the trolley that has moved to his own area. For this purpose, in one embodiment, information related to the current target picking item can be provided to the user terminal. Therefore, the user can confirm the information related to the current target picking item and appropriately pick the items in his own area into the plurality of picking bins loaded on the trolley.

[0036] Among them, the displayed products can be pre-assigned with fixed serial numbers according to types, or can be displayed in the order of serial numbers. And, in one embodiment, information related to the current picking target product including the serial number of the current picking target product can be provided, and the user can pick the current picking target product by confirming the serial number.

[0037] When the user has completely finished picking in their own area, the picking completion information can be input through the user terminal. In one embodiment, when the picking completion information is received, the next picking target product that has not been picked can be derived from the picking target list, and the cart can be moved by selecting the area where the next picking target product is displayed or the user terminal located in that area. This process can be continuously executed until all the picking target products in the picking target list are picked. When all the picking target products in the picking target list are picked, the cart can be moved to the packing area.

[0038] And, for example, in one embodiment, in order to appropriately move the cart to a specific area or the side of a specific user terminal, at least one of the entire map information, the area information where the cart cannot move due to the display of products, the cart movable area information, and the area information where the user can be located within the area can be utilized.

[0039] For example, the user terminal in one embodiment may include a computable device such as a smart phone or a tablet computer, that is, a smart device. The above functions can also be provided through an application program or a web browser on the smart device. And, since the user terminal may also need mobility or portability for the user to pick products in a specific area, in this case, the user terminal can be a portable device. Or it can also be a wearable device. That is, the user terminal can be a device that can be carried by the user or attached to a specific position and can be confirmed and operated at any time while picking products.

[0040] Or for example, according to one embodiment, the cart can automatically move towards the user terminal or the like, but the user can also move together with the cart for picking. That is, it is obvious that the picking can be performed not only in the way that the user is located in a specific area and the cart moves, but also in the way that the user and the cart move together to perform the product picking work.

[0041] For example, the cart can be in a movable form with 3 or 4 wheels attached to the bottom surface. The wheels can be operated by a driving module, and it can also be moved by the user, or can be equipped with a communication module or a processing module to move automatically. For example, when the user moves the cart, it can also automatically track the user by being equipped with a driving module, a detection module, or a processing module.

[0042] For example, 15 picking bins can be loaded and used on one cart, but it is not limited to this. That is, different numbers of picking bins can be loaded on one cart.

[0043] For example, as Figure 1 shown, when 15 picking bins are loaded on the cart, the cart can be composed of three layers, and each of the three layers can load 5 picking bins. And, for example, the picking bins can be numbered from the upper layer to the lower layer. That is, the first picking bin to the fifth picking bin can be located on the upper layer, the sixth picking bin to the tenth picking bin can be located on the middle layer, and the eleventh picking bin to the fifteenth picking bin can be located on the lower layer. However, it can also be configured in different ways, so it is not limited to this.

[0044] Figure 2 It is a conceptual diagram for explaining the concept of a proximity sensor-based merchandise picking assistance method according to another embodiment of the present invention.

[0045] Referring to Figure 2 , according to another embodiment of the present invention, a cart loaded with multiple picking bins can also move on a preset track. In this case, when the cart is at the reference location in the area where the current picking target merchandise is displayed, the track can stop operating, and thus, the cart can move to the area where the current picking target merchandise is displayed.

[0046] For example, in Figure 2 , the larger quadrilateral among the multiple quadrilaterals represented by the dashed line can represent a cart loaded with multiple picking bins, and the smaller quadrilateral can be the above-mentioned reference location. That is, when the cart reaches within a specified distance from the reference location, the track can determine that the cart has reached the area where the current picking target merchandise is displayed, and thus stop operating. Among them, a proximity sensor based on location-based service (LBS) can be located at the reference location, and based on the sensed value derived from the proximity sensor, it can be determined whether the cart is within a specified distance from the reference location.

[0047] And, there can be a light-emitting diode (LED) at the reference location. Or for example, the light-emitting diode can be in a constantly lit state to display the reference location to the user. Or for example, when the cart reaches within a specified distance, the light-emitting diode can emit light, and thus, it can also display to the user that the cart has reached the area where the user is located. However, since the light-emitting diode can operate in a flashing or lit state according to various conditions set, the operation of the above-mentioned light-emitting diode is not limited to this.

[0048] In other words, according to another embodiment, when the cart moves on the track and the cart reaches within a specified distance from the reference location on the track, the track stops and the user can perform the picking work. And when the user inputs the picking completion information through the user terminal, the track device can receive the picking completion information, and the track device can move the cart to the next area to perform the next picking work.

[0049] Also, according to an embodiment of the present invention, in addition to picking by moving the trolley as described above, it is also possible to easily manage many orders of large-order customer companies through a user terminal. Herein, a large-order customer company may refer to a customer company with the total number of orders being above a preset threshold, or may refer to a customer company preset by a manager, but is not limited thereto. Regarding this, it will be described later Figures 3 to 7 together.

[0050] Figures 3 to 7 FIG. showing a screen of a user terminal for managing and processing orders of a large-order customer company according to an embodiment of the present invention.

[0051] Figures 3 to 7 It may be a screen showing a method for managing and processing orders of a series of large-order customer companies.

[0052] First, referring to Figure 3 , login can be performed by inputting the account information of the user. Herein, the account information may consist of a username and a password, but additional certificates may also be used.

[0053] In an embodiment, when obtaining the account information from the user, login can be performed based on this, and information related to the current user's work can be provided to the screen. For example, information related to the current user's work may include all work information, work information of the work I am responsible for, or unprocessed work information.

[0054] The user can click on the menu button located at the upper right end of the above screen. Thus, in an embodiment, various information can also be provided. For example, in an embodiment, information related to a product request, information related to a product requester, information related to a shortage in stock, information related to product display, information related to a packaging material request, information related to order retrieval, information related to a vacation application, information related to sending multiple text messages, or information related to work query can be provided to the user through the menu.

[0055] For example, when the user clicks on work query, information related to work query can be confirmed. And, in an embodiment, when the user clicks on work query, information related to work query can be provided on the screen. Herein, the information related to work query can be divided into central work, work query (store), and work query (driver), and one selected by the user can be provided to the user.

[0056] For example, when the user clicks on work query (store), retrieval can be performed by inputting or confirming the date information located at the upper end of the next screen, and a work list and progress information corresponding to the corresponding date can be provided on the screen. Herein, the work list may contain at least one work information, and the progress information can be provided according to the work information.

[0057] After that, referring to Figure 4 , the user can select one of the job information in the job list and can provide information related to the detailed job included in the corresponding job information. Among them, the information related to the detailed job may include information related to the large order customer company, and this information can be classified by large order customer company. Among them, the user can select a specific large order customer company and confirm the list of products ordered by the specific large order customer company on the same screen.

[0058] After that, the user can select a large order customer company or can select and favorite a specific product in the list of products ordered by the large order customer company. Among them, favoriting can be used to prevent multiple users from repeating the picking work on the product list or products at the same time. When favoriting is selected, the person in charge of the corresponding job can be set as the user. Or for example, when the user wants to cancel after selecting favoriting, the user can also select to unfavorite. Among them, favoriting can also be used to request the user to confirm again through a pop-up window. The above screen can be composed of labels including favorite products, products I have favorited, and products I have completed. The above information related to the detailed job and the screen for performing favoriting can be the screen provided according to the favorite product label.

[0059] Referring to Figure 5 , when the user favorites a specific large order customer company or a specific product, the user can confirm the list of products of the favorite specific large order customer company or the favorite products by clicking on the "Products I Have Favorited" label at the top. When the user confirms that there is no abnormality in the list of products or products he has favorited, the user can start the picking work by selecting picking. For example, when starting to pick, the user can perform picking on the trolley that has arrived in his area. Or the user can also perform picking while walking with the trolley.

[0060] For example, when the user selects picking and starts picking, job information including job number, alias, generation date, and status can be provided on the screen, and information related to the picking object list can also be provided. The information related to the picking object list can list the picking object products in the picking object list through various methods. For example, the information related to the picking object list can also list the picking object products in each store so as to easily confirm the picking in each store. And the information related to the picking object list can provide information related to the picking object products, and the information related to the picking object products can include information such as product name, quantity, status, trading party, and display location. Among them, the customer can represent the large order customer company.

[0061] Also, in one embodiment, the serial number of the picking target product can also be provided through the screen. Among them, the serial number can be represented by barcode information, and only 3 digits can be displayed. In this case, when the last 3 digits of the product barcode are the same as the 3 digits displayed on the screen, the user can confirm that the corresponding product is the picking target product. Thus, the accuracy of the picking work can be improved.

[0062] After that, the user can select a specific picking target product from the above-mentioned picking target list. In one embodiment, the quantity information of each detailed store of the large order customer company that orders a large quantity of a specific picking target product can be provided to the user. Among them, the quantity information of each detailed store can include information related to the processing status, store name, quantity, collection quantity, and out-of-stock. The user can pick the target product by confirming the quantity of each detailed store, and can increase the collection quantity while picking. For example, when more collection quantities are increased relative to the picking quantity, the collection quantity can also be reduced again.

[0063] Refer to Figure 6 , when the user completes picking the same quantity as the quantity of each detailed store, after setting the collection quantity to be the same, the processing status can be converted to completed. Among them, the user can also convert the screen to the product list of other large order customer companies by selecting the large order customer company located at the upper end.

[0064] For example, when the user completes picking all the products of the large order customer company in the current picking and converts the status of all the products to completed, the completion process located at the lower end of the screen can be executed. In this case, all the products of the corresponding large order customer company can be regarded as picked, and the user can continue to perform the picking work by selecting the next large order customer company. And when the user performs the completion process on all the large order customer companies or all the products in their collection, they can return to the screen displaying the work information to perform the completion process on the work.

[0065] Refer to Figure 7, when the user finishes processing a task, they can confirm that the corresponding job has been completed by re-querying the task, and can also confirm that the progress has changed accordingly. For example, the user can also re-select a task whose progress has not reached 100% and perform further picking operations through the above process. Or the user can also click on the tasks I am responsible for to confirm information related to the tasks or goods that they have completed processing, information related to unprocessed tasks or goods, or information related to tasks or goods in preparation. Furthermore, the user can confirm information related to the completed or uncompleted goods included in the picking object list of the corresponding task by selecting a specific task. Among them, after the user selects a specific task, they can also confirm by filtering information related to the completed or uncompleted goods included in the specific task based on the store name, status, or whether there is a change. Among them, the information related to the completed or uncompleted goods included in the specific task may include the store name, quantity, outbound quantity (or collection quantity), receiving vehicle, staff, or status.

[0066] Figure 8 The block diagram of the commodity picking assistance device based on a proximity sensor according to an embodiment of the present invention.

[0067] Referring to Figure 8 , the commodity picking assistance device 800 based on a proximity sensor according to an embodiment of the present invention may include at least one processor 810, a memory 820, and a storage device 830. For example, in one embodiment, the user terminal can be a computable and portable user terminal such as a smart phone or a tablet computer, and can provide the functions of the embodiment through an application. Or for example, the commodity picking assistance device 800 based on a proximity sensor can send or receive information with the user terminal and perform various operations. Or for example, the commodity picking assistance device 800 based on a proximity sensor may further include a driving module or a communication module, and the driving module can be a driving module for a track or a driving module for a cart.

[0068] The processor 810 can execute program instructions stored in the memory 820 and / or the storage device 830. The processor 810 can refer to a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor for executing the method of the present invention. The memory 820 and the storage device 830 can be composed of volatile storage media and / or non-volatile storage media. For example, the memory 820 can be composed of a read only memory (ROM) and / or a random access memory (RAM).

[0069] The memory 820 may store at least one instruction executed by the processor 810. The at least one instruction may include: an instruction to derive the current picking target item from the picking item list, an instruction to select a first user terminal located in a first area where the current picking target item is displayed, an instruction to move a cart including a plurality of picking bins within a predetermined distance from the first user terminal, an instruction to stop the movement of the cart when the cart is within the predetermined distance from the first user terminal, an instruction to provide information related to the current picking target item to the first user terminal, and an instruction to derive the next picking target item from the picking item list when the picking completion information is received from the first user terminal. Among them, the distance between the cart and the first user terminal may be determined based on a proximity sensor. Alternatively, the proximity sensor may also include a proximity sensor based on location-based service (LBS).

[0070] For example, the at least one instruction may further include: an instruction to select a second user terminal located in a second area where the next picking target item is displayed and an instruction to move the cart within a predetermined distance from the second user terminal. Among them, a track may be provided in the path between the first area and the second area, and the cart may also move on the track.

[0071] Alternatively, for example, a predetermined fixed serial number may be assigned to each of the current picking target items, the current picking target items may be arranged in the first area based on the serial numbers, and the information related to the current picking target items provided to the first user terminal may also include the serial numbers of the current picking target items.

[0072] In addition, the picking item list may be filtered based on information related to a specific large order customer company among a plurality of large order customer companies with an order total quantity above a preset threshold. Furthermore, the picking item list may include information related to the required quantity of the items ordered by the specific large order customer company. When information related to having picked the ordered items to the same quantity as the collection quantity of the ordered items and information related to converting the status of the ordered items to completed is received from the first user terminal, it may be determined that the picking completion information is received. Among them, the user may also sort the picking item list according to the picking target item information of the large order customer company or according to the order information of the large order customer company of the items.

[0073] Figure 9 It is a flowchart of a commodity picking assistance method based on a proximity sensor according to an embodiment of the present invention.

[0074] Refer to Figure 9, according to an embodiment, the current picking target item can be derived from the picking item list (step S910). In an embodiment, the first user terminal located in the first area where the current picking target item is displayed can be selected (step S920). Among them, in addition to the first user terminal, the reference terminal or the reference location located in the first area can also be selected. That is, in an embodiment, the reference position information for moving the cart can be obtained.

[0075] Moreover, in an embodiment, the cart including a plurality of picking bins can be moved within a specified distance from the first user terminal (step S930). When the cart is within the specified distance from the first user terminal, the movement of the cart can be stopped (step S940). Among them, the distance between the cart and the first user terminal can be determined based on the proximity sensor. That is, it can be determined whether the cart is within the specified distance from the first user terminal based on the proximity sensor. For example, the proximity sensor may further include a proximity sensor based on location-based service (LBS).

[0076] For example, in an embodiment, when the cart moves along the direction of the first user terminal, the moving speed of the cart can also be controlled. For example, in an embodiment, the moving speed of the cart can be controlled based on the distance information between the cart and the first user terminal, the information related to whether the first user corresponding to the first user terminal is located in the designated area (for example, the first area) of the first user, and the level information of the historical processing speed of the first user. Among them, in an embodiment, in order to derive the distance information between the cart and the first user terminal, the reference position information for moving the cart and the current position information of the cart can be obtained. The current position information of the cart can be obtained by detecting the position of the cart based on Wi-Fi communication, etc., but various methods can be used, so it is not limited thereto.

[0077] According to an embodiment, the user detection sensor or the indoor detection sensor that can detect whether the first user is located in the above-mentioned designated area can be located in the above-mentioned designated area (for example, the first area). Thus, the information related to whether the first user is located in the above-mentioned designated area can be obtained. And, in an embodiment, based on the historical processing detail information of multiple users, the level of the processing speed of each user can be derived. That is, in an embodiment, based on the historical processing detail information, the information related to the picking quantity per historical time of the user can be derived, and based on the average value of the information related to the picking quantity per historical time, the level information of the historical processing speed of the user can be derived.

[0078] Specifically, in one embodiment, the distance information between the above-mentioned trolley and the above-mentioned first user terminal, the information regarding whether the first user corresponding to the above-mentioned first user terminal is located within the designated area (e.g., the first area) of the above-mentioned first user, and the level information of the historical processing speed of the above-mentioned first user can be respectively used as factors or elements for determining the moving speed. For example, the moving speed of the trolley can be determined as shown in Mathematical Formula 1. However, considering the work safety issue, the moving speed of the above-mentioned trolley can be restricted according to the maximum moving speed. For example, the maximum moving speed can be 10 km / h. That is, the moving speed of the trolley can be calculated by Mathematical Formula 1, but when the calculated value exceeds the maximum moving speed, the moving speed of the trolley can be fixed at the maximum moving speed.

[0079] Mathematical Formula 1

[0080]

[0081] In Mathematical Formula 1, v can represent the moving speed of the trolley, and the unit can be km / h. d can represent the distance information between the above-mentioned trolley and the above-mentioned first user terminal, and the unit can be m. And, a can represent the information regarding whether the user is located within the designated area. When the user is located within the designated area, it can take a value of 1, and when the user is not located within the designated area, it can take a value of 0. b can derive the level information of the user's historical processing speed. According to the level information derived from the historical processing detail information, it can take any value among 0, 1, and 2. That is, the level information can be divided into one of three types based on the historical processing detail information, and the value of b can be determined according to each level.

[0082] For example, when the average value of the information regarding the picking quantity per historical time is less than the first threshold, it can be classified as slow processing speed and determined as the third level. In this case, the value of b can be determined as 0. And, when the average value of the information regarding the picking quantity per historical time is above the first threshold and less than the second threshold, it can be classified as average processing speed and determined as the second level. In this case, the value of b can be determined as 1. And, when the average value of the information regarding the picking quantity per historical time is above the second threshold, it can be classified as fast processing speed and determined as the first level. In this case, the value of b can be determined as 2.

[0083] Moreover, when the above-mentioned level information is not included in the above-mentioned historical processing details information for more than one month, that is, when the user has worked for less than 1 month, even if the average value of the information related to the picking quantity per historical time is above the first threshold, the level information can be determined as the third level. And when the above-mentioned level information is not included in the above-mentioned historical processing details information for more than three months, that is, when the user has worked for less than 3 months, even if the average value of the information related to the picking quantity per historical time is above the second threshold, the level information can be determined as the second level.

[0084] After that, in one embodiment, information related to the above-mentioned current picking target item may be provided to the above-mentioned first user terminal (step S950). When the picking completion information is received from the above-mentioned first user terminal, the next picking target item may be derived from the above-mentioned picking item list (step S960). And, in one embodiment, the second user terminal located in the second area where the above-mentioned next picking target item is displayed may be selected, and the above-mentioned cart may be moved within a specified distance from the above-mentioned second user terminal. That is, in one embodiment, when the picking of the current picking target item is completed, the next picking target item may be derived and moved to the area where the next picking target item is located through the above-mentioned process, so as to perform the picking work of the next picking target item.

[0085] For example, a track may be provided on the path of the above-mentioned first area or the path between the above-mentioned first area and the above-mentioned second area, and the above-mentioned cart may also move on the above-mentioned track. In this case, the above-mentioned reference location may be located at a specific location on the track, and a light-emitting diode (LED) may be mounted at the specific location. However, the track does not necessarily exist, and based on information related to the area where the items are displayed or the area where the cart can move, etc., the cart operation driving module moves towards the first area or the second area.

[0086] And, according to one embodiment, a predetermined fixed serial number may be assigned to each item, and the above-mentioned current picking target item may be arranged in the above-mentioned first area based on the above-mentioned serial number. And the information related to the above-mentioned current picking target item provided to the above-mentioned first user terminal may include the serial number of the above-mentioned current picking target item.

[0087] Furthermore, although not shown in Figure 9 it may be possible to filter the above-mentioned picking item list based on information related to a specific large order customer company among multiple large order customer companies with an order total quantity above a preset threshold.

[0088] In addition, the above picking product list may include information related to the required quantity of the products ordered by the above-mentioned specific large order customer company. When receiving, from the above first user terminal, the goods collection information of the above ordered products related to the fact that the above ordered products have been picked to the same quantity as the goods collection quantity of the above ordered products and the information related to converting the status of the above ordered products to completed, it can be determined that the above picking completion information has been received. In this case, the user can also sort the above picking product list according to the picking target product information of the large order customer company or the order information of the large order customer company of the products.

[0089] The Figure 9 operation described together can be taken as an example and is part of the multiple operations in an embodiment of the present invention. That is, even if not shown in Figure 9 , embodiments of the present invention can also execute multiple operations or part of the multiple operations described together with Figures 1 to 8 , which is obvious.

The computer-readable storage medium includes all types of storage devices that store data readable by a computer system. In addition, the computer-readable storage medium can be dispersed in computer systems connected through a network and store and run the computer-readable program or code in a distributed manner.

[0091] Moreover, the computer-readable storage medium can include hardware devices dedicated to program instructions, such as read-only memory (ROM), random access memory (RAM), flash memory, etc. The program instructions can include not only machine language codes made by a compiler, but also high-level language codes that can be run by a computer using an interpreter, etc.
