[0011] (Summary of the embodiment) The electronic signage control system of the embodiment is generally configured to include a plurality of display devices that receive and display content related to products, a plurality of store terminal devices that are installed in each of a plurality of stores that stock and sell products and transmit inventory information related to the inventory status of the products, and a control device that acquires inventory information from the plurality of store terminal devices, and, if there is a store among the plurality of stores whose inventory status of products satisfies predetermined control conditions, controls the content to be transmitted to display devices within a predetermined control range based on that store so that it is different from the content transmitted to other display devices.

[0012] When the stock of the advertised product is low, this digital signage control system sets a control range based on the stores with low stock.Then, the digital signage control system causes display devices included in this control range to display content different from the content displayed by display devices outside the control range, so that more appropriate content can be presented to those who wish to purchase the product than if this configuration was not adopted.

[0013] [Embodiment Mode] (Overview of Digital Signage Control System 1) FIG. 1(a) is a diagram showing an example of an electronic signage control system according to an embodiment, and FIG. 1(b) is an example of a block diagram of a display device. FIG. 2(a) is an example of a block diagram of a store terminal device according to an embodiment, FIG. 2(b) is an example of a block diagram of a control device, and FIG. 2(c) is an example of a block diagram of a display device installed on a mobile object. FIG. 3(a) is a diagram showing an example of a control range set by a control device according to an embodiment, and FIG. 3(b) is a graph for explaining an example of a prediction of out-of-stock of a product. In FIG. 3(b), the horizontal axis is time t and the vertical axis is inventory amount L.

[0014] In the drawings relating to the embodiments described below, the ratio between figures and shapes may differ from the actual ratio and shapes. In Fig. 1(b) to Fig. 2(c), the flow of main signals and information is indicated by arrows.

[0015] The electronic signage control system 1 of this embodiment is, as an example, a system that appropriately controls so-called digital signage (electronic signage) in accordance with inventory, which uses display devices 2 installed outdoors, in stores, public spaces, on public transport, etc. to advertise products 9 for sales promotion.

[0016] Specifically, as shown in FIG. 1(a) to FIG. 2(c), the digital signage control system 1 includes a plurality of display devices 2 that receive and display content 200 related to a product 9, and a plurality of stores 4 that stock and sell the product 9 and store inventory information S related to the stock status of the product 9. 11 A plurality of store terminal devices 5 transmit stock information S 11 and if there is a store 4 among the multiple stores 4 whose inventory status of the product 9 satisfies a predetermined control condition, a control device 6 that controls the content 201 to be transmitted to display devices 2 within a predetermined control range 631 based on the store 4 so that the content 201 is different from that transmitted to other display devices 2.

[0017] The content to be transmitted to the display device 2 within the control range 631 is referred to as the content 201 to distinguish it from the content 200. That is, the display device 2 within the control range 631 displays the content 201, and the display device 2 outside the control range 631 displays the content 200. In addition, the other display device 2 is a display device 2 not included in the control range 631.

[0018] The control device 6 determines that a store 4 in which the inventory of the product 9 is below a predetermined inventory threshold Th1 is a store that satisfies the control conditions, and controls the content 201 to be sent to display devices 2 within a control range 631 based on the store 4 so that the content 201 is displayed at a lower frequency than other display devices 2.

[0019] The control device 6 performs control so that within a control range 631 based on a store 4 that satisfies the above-mentioned control condition, the closer the distance to the store 4 is, the lower the display frequency of the content 201 becomes.

[0020] The control device 6 predicts which store 4 will run out of stock within a predetermined period T based on the inventory status, and controls the content 201 to be sent to the display devices 2 within a control range 631 based on that store 4 so that the content 201 is displayed at a lower frequency than the other display devices 2.

[0021] The control device 6 determines that a store 4 whose inventory of product 9 is equal to or greater than a predetermined excess inventory threshold Th2 is a store 4 that satisfies the control conditions, and controls the content 201 to be sent to display devices 2 within a control range 631 based on the store 4 so that the content 201 is displayed at a higher frequency than other display devices 2.

[0022] The control device 6 performs control so that within a control range 631 based on a store 4 with excess stock threshold value Th2 or more, the closer the distance to the store 4 is, the higher the display frequency of the content 201 becomes.

[0023] As shown in Fig. 1(a), the control device 6 is connected to a plurality of display devices 2 and a plurality of stores 4 via a network 8. The network 8 is, for example, the Internet, a wireless or wired network, etc. In the present embodiment, the network 8 is, for example, the Internet.

[0024] (Configuration of display device 2) 1(b), the display device 2 includes a display unit 20, a communication unit 21, and a display control unit 22. The display unit 20 is a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display that displays the content 200 and the content 201. Examples of the display unit 20 include a large display installed on the roof or side of a building, a medium-sized display installed in front of the store 4 or inside the store, and a small display installed on a train or vehicle. The communication unit 21 is configured to exchange information and signals with the control device 6 via the network 8.

[0025] The display control unit 22 is a microcomputer including a CPU (Central Processing Unit) that performs calculations and processing on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, and a ROM (Read Only Memory). The ROM stores, for example, a program for operating the display control unit 22. The RAM is used, for example, as a storage area for temporarily storing calculation results.

[0026] The display control unit 22 receives the content information S from the control device 6 via the communication unit 21 and the network 8. 22 Get this content information 22 is information about the content 200 and the content 201 to be displayed on the display unit 20. The display control unit 22 22 The content signal S1 is generated based on the above and output to the display unit 20.

[0027] The display control unit 22 has identification information S2 for identifying the display device 2. The control device 6 grasps the installation position of the display device 2 based on the identification information S2.

[0028] The display device 2 is not limited to being installed at a predetermined installation position such as outdoors or in a store, and may be installed, for example, on a moving vehicle 3. The display device 2 is also installed, for example, in a store 4 that sells products 9.

[0029] 1(a) is, for example, public transportation such as a taxi, a bus, or a train. Since the display device 2 installed outdoors or in a store is fixed, for example, the control device 6 can be configured to know the installation location based on the identification information S2. However, it is difficult to know the location of the display device 2a installed in the moving object 3 based on the identification information S2 alone.

[0030] Therefore, the display device 2a installed in the moving object 3 further includes a location information acquisition unit 23 that generates location information S4 by a global positioning system (GPS), as shown in Fig. 2(c). In the following, the display device 2a installed in the moving object 3 will be referred to as the display device 2 unless otherwise specified.

[0031] The content 200 and the content 201 may be still images or moving images, and may also include sound.

[0032] (Configuration of store terminal device 5) As shown in FIG. 2(a), the store terminal device 5 includes an inventory management unit 50, a communication unit 51, and an inventory control unit 52. The inventory management unit 50 manages the incoming amount, the number of purchases and sales, and the inventory amount L of the product 9 being sold. The inventory management unit 50 generates inventory amount information S relating to the inventory amount L of the product 9 to be displayed on the display device 2. 10to the inventory control unit 52. Note that the inventory management unit 50 manages inventory in cooperation with a POS (Point of Sale) system of the store 4, but is not limited to this, and may manage inventory based on values ​​input via an input device, or a combination of these.

[0033] The communication unit 51 is configured to exchange information and signals with the control device 6 via the network 8.

[0034] The inventory control unit 52 is a microcomputer that is composed of a CPU, RAM, ROM, etc. The inventory control unit 52 has identification information 520 that identifies the store terminal device 5. The inventory control unit 52 stores inventory amount information S 10 and inventory information S including identification information 520 11 The control device 6 generates the inventory information S 11 The location of the store 4 in which the store terminal device 5 is installed is identified based on the identification information 520 included in the store terminal device 5 .

[0035] (Configuration of control device 6) As shown in FIG. 2(b), the control device 6 includes a prediction unit 60, a storage unit 61, a communication unit 62, and a control unit 63.

[0036] The prediction unit 60 predicts whether the product 9 will run out of stock within a predetermined period T. The storage unit 61 is, for example, a storage device such as a hard disk drive (HDD) or a solid state drive (SDD). The storage unit 61 has a database 610 for recognizing the installation location based on the identification information S3 of the display device 2 and the identification information 520 of the store terminal device 5. The communication unit 62 is configured to exchange information and signals with the display device 2 and the store terminal device 5 via the network 8. The period T is, for example, one day, but is not limited to this.

[0037] The control unit 63 is a microcomputer composed of a CPU, RAM, ROM, etc. The control unit 63 has control range information 630, an inventory threshold value Th1, and an excess inventory threshold value Th2. The control range information 630 is information about a control range 631. As an example, the control range 631 is a circular area centered on a store 4 that satisfies the control conditions, and is set as an area including the adjacent store 4 and the display device 2, or as an area within walking distance to the store 4. Note that the control range 631 may be an area having a shape other than a circle, taking into account, for example, the geographical conditions of the store 4.

[0038] The inventory threshold value Th1 is, for example, about 30% of the incoming amount, but is not limited to this value, and the excess inventory threshold value Th2 is, for example, about 50% of the incoming amount, but is not limited to this value.

[0039] An example of control when the stock of the product 9 is low and an example of control when the stock of the product 9 is high will be described below.

[0040] -If item 9 is low in stock The control unit 63 receives the stock information S in real time from the store terminal device 5. 11 The real-time acquisition is, for example, when the stock amount L of the product 9 changes, but is not limited to this. In addition, the control unit 63 periodically acquires the stock information S several times a day. 11 The method may be configured to obtain

[0041] The control unit 63 receives the stock information S 11 The control unit 63 checks the stock of the product 9 that is the advertisement target based on the stock threshold value Th1. If the stock is equal to or less than the stock threshold value Th1, the control unit 63 determines that the stock of the product 9 is low, and sets the control range 631 based on the stores 4 whose stock is equal to or less than the stock threshold value Th1.

[0042] The control unit 63 identifies the display device 2 present within the control range 631 based on the database 610 and the identification information S2 of the display device 2. Then, as shown in FIG. 3(a), the control unit 63 transmits to the display device 2 within the control range 631 content information S for displaying a content 201 different from the content 200 displayed by the display device 2 outside the control range 631. 22 Output.

[0043] At least one of the display contents and the display frequency of the content 201 when the stock is low is different from that of the content 200. When the display contents of the content 201 are different from those of the other content 200, as an example, the display contents indicate that the stock of the product 9 is low.

[0044] Furthermore, the control unit 63 performs control so that the display frequency of the content 201 decreases as the distance to the store 4 becomes closer within the control range 631 based on the store 4 that satisfies the control condition.

[0045] The control unit 63 calculates the distance from the store 4 whose stock is equal to or less than the stock threshold value Th1 based on the database 610 and the identification information S2 of the display device 2. In FIG. 3(a), the display devices 2 that are closest to the store 4 whose stock is equal to or less than the stock threshold value Th1 are numbered No. 1 to No. 5 in order. The display device 2 No. 3 is installed in the store 4. The display device 2 No. 5 is installed in a mobile object 3. Note that the display device of the mobile object 3 is shown as the display device 2 in FIG. 3(a). Furthermore, the display device 2 No. 3 may increase its display frequency instead of decreasing it when the stock of the product 9 in the store 4 in which it is installed is greater than the stock threshold value Th1.

[0046] The control unit 63 controls the content information S so that the display frequency of the content 201 decreases in the order of No. 5 to No. 1. 22 The control unit 63 controls, for example, the display device 2 to display the content information S 22 When the content information S per unit time is displayed every time the content information S is acquired, 22 In addition, the control unit 63 controls the display device 2 to transmit the content information S22 In the case where the content 201 based on the content information S is displayed at a predetermined period, 22 The display frequency of the content 201 can be controlled to be reduced by including information on a cycle for reducing the display frequency in the content 201, but this is not limited to the above.

[0047] The display device 2 of the store 4 whose stock has fallen below the stock threshold Th1 may display less frequently than the display device 2 of No. 1, or may display the same, and is not limited to this.

[0048] If there is a lot of stock The control unit 63 receives the stock information S 11 The control unit 63 checks the stock of the product 9 that is the advertisement target based on the excess stock threshold value Th2. If the stock is equal to or greater than the excess stock threshold value Th2, the control unit 63 determines that the stock of the product 9 is excessive, that is, that sales are not good, and sets a control range 631 based on the stores 4 whose stock is equal to or greater than the excess stock threshold value Th2.

[0049] As shown in FIG. 3(a), the control unit 63 transmits to the display device 2 within the control range 631 content information S for displaying a content 201 different from the content 200 displayed by the display device 2 outside the control range 631. 22 Output.

[0050] When there is excess inventory, the content 201 differs from the content 200 in at least one of the display contents and the display frequency. When the display contents of the content 201 differ from the other contents 200, for example, the display contents may be more eye-catching or lower in price.

[0051] Furthermore, the control unit 63 controls the display frequency of the content 201 to be increased as the distance to the store 4 becomes closer within the control range 631 based on the store 4 with the excess stock threshold value Th2 or more.

[0052] The control unit 63 controls the content information S so that the display frequency of the content 201 increases in the order of No. 5 to No. 1 shown in FIG.22 The control unit 63 controls, for example, the display device 2 to display the content information S 22 When the content information S per unit time is displayed every time the content information S is acquired, 22 The control unit 63 also controls the display device 2 to transmit the content information S 22 In the case where the content 201 based on the content information S is displayed at a predetermined period, 22 The display frequency of the content 201 is controlled to be increased by including information on a period for increasing the display frequency in the display frequency information, but is not limited to this. Note that the display device 2 of No. 3 may be configured to decrease the display frequency instead of increasing it when the stock of the product 9 in the store 4 in which it is installed is equal to or less than the stock threshold value Th1.

[0053] - When stock shortage is predicted The prediction unit 60 uses the acquired stock information S 11 Based on this, it is predicted which stores 4 will run out of stock within a predetermined period T. In FIG. 3(b), the stock threshold value Th1 is indicated by a dashed line.

[0054] The prediction unit 60 may make the prediction based on, for example, the past decrease in stock of a similar product, the decrease in stock of products 9 in other stores 4, or using artificial intelligence, but is not limited to these. As an example, as shown in Fig. 3(b), when the prediction unit 60 starts the prediction at time t1, it predicts whether the stock will be equal to or less than the stock threshold value Th1 from time t1 to time t2, which is a period T later. In Fig. 3(b), as an example, the cases where the stock is equal to or less than the stock threshold value Th1 and the cases where the stock is greater than the stock threshold value Th1 are shown by dotted lines.

[0055] The prediction unit 60 generates prediction information S indicating the prediction result. 21 The control unit 63 outputs the prediction information S 21 If the stock is expected to run out within the period T based on the above, the control range 631 is set based on the store 4 where the stock is expected to run out.

[0056] An example of the operation of the digital signage control system 1 according to this embodiment will be described below with reference to the flowchart of FIG.

[0057] (operation) The control unit 63 of the control device 6 receives inventory information S from a plurality of stores 4 via the communication unit 62 and the network 8. 11 Obtain (Step 1).

[0058] The control unit 63 receives the plurality of pieces of stock information S 11 Based on this, a store whose inventory of the advertised product 9 is equal to or less than the inventory threshold value Th1 is searched for. If there is a store 4 whose inventory of the product 9 is equal to or less than the inventory threshold value Th1 (Step 2: Yes), the control unit 63 sets the control range 631 based on the store 4 (Step 3).

[0059] The control unit 63 transmits the content 201 for when stock is low to the store 4 included in the control range 631 (Step 4), and ends the process.

[0060] Here, in step 2, if the inventory is greater than inventory threshold value Th1 (Step 2: No), the control unit 63 compares whether the inventory is greater than or equal to excess inventory threshold value Th2. If there is a store 4 where the inventory of product 9 is greater than or equal to excess inventory threshold value Th2 (Step 5: Yes), the control unit 63 sets the control range 631 based on that store 4 (Step 6).

[0061] The control unit 63 transmits the content 201 when the stock is high to the store 4 included in the control range 631 (Step 7), and ends the process.

[0062] Furthermore, in step 5, if there is a store 4 where the stock of the product 9 is more than the stock threshold value Th1 and less than the excess stock threshold value Th2 (Step 5: No), the control unit 63 causes the prediction unit 60 to predict whether the store 4 will run out of stock within the period T. If a stockout is predicted within the period T (Step 8: Yes), the control unit 63 sets a control range 631 based on the store 4 where the stockout is predicted (Step 9).

[0063] The control unit 63 transmits the content 201 for when stock is predicted to run out to the stores 4 included in the control range 631 (Step 10), and ends the process. The content 201 for when stock is predicted to run out has, for example, a display content indicating that the stock of the product 9 is low, and is displayed at a low frequency.

[0064] Furthermore, in step 8, if stock-out is not predicted (Step 8: No), the control unit 63 determines that there is an appropriate amount of stock (Step 11), and ends the process.

[0065] Here, the order of steps 2 to 4, steps 5 to 7, and steps 8 to 10 is not limited to this, and the order may be changed. 11 Do this every time you obtain a new one.

[0066] (Effects of the embodiment) The digital signage control system 1 according to the present embodiment can present appropriate content. Specifically, when the stock of the advertised product 9 is low, the digital signage control system 1 sets a control range 631 based on the store 4 with low stock. The digital signage control system 1 then causes the display devices 2 included in the control range 631 to display content 201 that is different from the content 200 displayed by the display devices 2 outside the control range 631. This makes it possible to present appropriate content 201 to a person who wishes to purchase the product 9, compared to a case where this configuration is not adopted.

[0067] The electronic signage control system 1 displays the content 201 not only on a stationary display device 2 but also on a display device 2a installed on a mobile body 3 if the display device 2a is included in the control range 631. Therefore, compared to a case where this configuration is not adopted, it is possible to prevent a situation where a person gets off the mobile body 3 to try to purchase product 9 but is unable to do so because it is out of stock.

[0068] When there is more inventory than expected, in other words, when sales are not as good as expected, the electronic signage control system 1 uses the relevant store 4 as a reference and displays content 201 promoting sales on the display devices 2 within the control range 631, so that potential buyers who are close to the store 4 can be encouraged to make purchases, compared to when this configuration is not adopted.

[0069] The digital signage control system 1 changes the content 201 as it approaches the reference store 4 within the control range 631, and therefore can present a more appropriate content 201 to a potential purchaser, compared to a case in which this configuration is not adopted.

[0070] When the stock is low, the electronic signboard control system 1 can reduce the frequency of displaying the content 201 or display a message indicating that the stock is low, so compared to a case where this configuration is not adopted, it is possible to prevent a potential purchaser from coming to purchase the product but being unable to make the purchase because the product is out of stock.

[0071] The electronic signage control system 1 can predict before the stock level falls below the stock threshold Th1 and display the content 201 on the display device 2 within the control range 631, thereby preventing stock shortages and inability to purchase the product compared to when the content is not changed until the stock level falls below the stock threshold.

[0072] In another embodiment, inventory information S regarding the inventory status of products 9 is transmitted from a plurality of store terminal devices 5 installed in each of a plurality of stores 4. 11 and if there is a store 4 among a plurality of stores 4 whose inventory status of the product 9 satisfies a predetermined control condition, a predetermined control range 631 is set based on the store 4, and among a plurality of display devices 2 displaying the content 200 related to the product 9, the content 201 transmitted to the display devices 2 within the control range 631 is controlled so as to be different from that transmitted to the other display devices 2. This electronic signage control method can present appropriate content.

[0073] The electronic signage control system 1 and the electronic signage control method according to the above-described embodiment may be realized, for example, in part by a program executed by a computer, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc., depending on the application.
