[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are given the same reference numerals and the description will be omitted as appropriate.

[0014] (First embodiment) 1 is a diagram for explaining a usage environment of a management device 10 according to this embodiment. The management device 10 is used together with a display device 20 and a product shelf 30.

[0015] The display device 20 is, for example, an electronic shelf label or signage, and is provided within a facility. The facility is, for example, a store or a warehouse at a logistics base. In the following description, the facility is a store. The display device 20 is attached to a product shelf 30. A display device 20 is provided for each of a plurality of types of products, and displays information relating to the product corresponding to the display device 20 (hereinafter, referred to as product information). The product information is stored in a rewritable state in the display device 20. The product information includes, for example, the product name and price, and may further include a product description.

[0016] The management device 10 manages the display devices 20. For example, the management device 10 manages the association between the display devices 20 and the products, and also manages information indicating the status of the display devices 20 (hereinafter referred to as status information). Each of the multiple display devices 20 is assigned unrewritable identification information and rewritable identification information. The unrewritable identification information is stored in the display device 20 in a non-rewritable state, and the rewritable identification information is stored in the display device 20 in a rewritable state. The management device 10 manages the display devices 20 using the unrewritable identification information and the rewritable identification information.

[0017] The display device 20 has a wireless communication function. The display device 20 receives product information from the management device 10 using this wireless communication function, and also repeatedly transmits status information of the display device 20 or information for generating status information to the management device 10. In this transmission, the display device 20 also transmits rewritable identification information. This allows the management device 10 to identify which display device 20's status the received information indicates. The wireless communication function of the display device 20 is powered by a battery built into the display device 20. The status information of the display device 20 includes, for example, information indicating the remaining capacity of the battery.

[0018] 2 is a diagram showing an example of information stored in the display device 20. As described above, the display device 20 stores the unrewritable identification information and the rewritable identification information.

[0019] The display device 20 also stores status information of the display device 20 or information for generating the status information. The status information includes, for example, as described above, information indicating the remaining battery level of the display device 20 (e.g., the latest voltage), but may also include at least one of the accumulated operating time or accumulated display time of the display device 20, and the number of times the display device 20 has communicated with the outside (e.g., the management device 10) since the battery has been replaced. However, the accumulated operating time, accumulated display time, and number of times of communication only need to be stored in the management device 10, and therefore may not be stored in the display device 20.

[0020] The display device 20 also stores product information to be displayed by the display device 20. This product information includes, for example, the product name and price.

[0021] 3 is a diagram showing an example of a functional configuration of the management device 10. In the example shown in this figure, the management device 10 includes a first update section 110, a second update section 120, and a display processing section .

[0022] The first updating unit 110 updates the device identification information storage unit 140 .

[0023] As an example, the device identification information storage unit 140 stores the status information, non-rewritable identification information, and rewritable identification information of the display device in association with one another. The first update unit 110 then updates the status information of the display device 20 using information acquired from the display device 20 (e.g., the status information itself, or information for generating the status information). This update is performed, for example, periodically.

[0024] Furthermore, the first update unit 110 updates the rewritable identification information corresponding to the non-rewritable identification information. The rewritable identification information is updated, for example, when the product corresponding to the display device 20 is changed.

[0025] The second update unit 120 updates the product identification information storage unit 150. The product identification information storage unit 150 stores rewritable identification information in association with product identification information. The product identification information storage unit 150 associates the display device 20 with the product corresponding to the display device 20. When the product corresponding to the display device 20 is changed, it is not necessary to update the association between the rewritable identification information and the product identification information.

[0026] The display processing unit 130 performs processing for displaying the product information on the display device 20. Specifically, the display processing unit 130 identifies rewritable identification information corresponding to the product identification information of the product in the product identification information storage unit 150. Then, the display processing unit 130 performs processing for displaying the product information corresponding to the rewritable identification information on the display device 20 corresponding to the rewritable identification information.

[0027] In the example shown in the figure, the product information is stored in a product information storage unit 160. The product information storage unit 160 stores product identification information and product information of the product corresponding to the product identification information in association with each other.

[0028] In the example shown in the figure, the device identification information storage unit 140, the product identification information storage unit 150, and the product information storage unit 160 are part of the management device 10. However, at least one of these may be located outside the management device 10. In addition, the product identification information storage unit 150 and the product information storage unit 160 may be integrated into one unit.

[0029] 4 is a diagram showing an example of information stored in device identification information storage unit 140. Device identification information storage unit 140 stores, for each of a plurality of pieces of non-rewritable identification information, state information of display device 20 corresponding to the non-rewritable identification information, and rewritable identification information assigned to the display device 20. Note that device identification information storage unit 140 may have a table that stores non-rewritable identification information and state information in association with each other, and a table that stores non-rewritable identification information and rewritable identification information in association with each other.

[0030] 5 is a diagram showing an example of information stored in the product identification information storage unit 150. The product identification information storage unit 150 stores, for each piece of rewritable identification information, the product identification information of the product corresponding to that rewritable identification information.

[0031] When changing a product corresponding to a certain display device 20, the product identification information storage unit 150 is not updated. Instead, the rewritable identification information stored in the device identification information storage unit 140 is updated.

[0032] 6 is a diagram showing an example of information stored in the product information storage unit 160. The product information storage unit 160 stores, for each product identification information, product information of the product corresponding to that product identification information. This product information includes, for example, information to be displayed on the display device 20. The information displayed on the display device 20 includes, for example, the product name and price, and may further include a description of the product.

[0033] 7 is a diagram showing an example of the product identification information storage unit 150 when the product identification information storage unit 150 also serves as the product information storage unit 160. In this case, the product identification information storage unit 150 stores, for each rewritable identification information, the product identification information and product information of the product corresponding to that rewritable identification information.

[0034] 8 is a diagram showing an example of the hardware configuration of the management device 10. The management device 10 includes a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060.

[0035] The bus 1010 is a data transmission path for transmitting and receiving data among the processor 1020, memory 1030, storage device 1040, input / output interface 1050, and network interface 1060. However, the method of connecting the processor 1020 and the like to each other is not limited to bus connection.

[0036] The processor 1020 is implemented by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

[0037] The memory 1030 is a main storage device realized by a RAM (Random Access Memory) or the like.

[0038] The storage device 1040 is an auxiliary storage device realized by a hard disk drive (HDD), a solid state drive (SSD), a memory card, a read only memory (ROM), or the like. The storage device 1040 stores program modules that realize each function of the management device 10 (for example, the first update unit 110, the second update unit 120, the display processing unit 130, and the third update unit 170 and the update information acquisition unit 180 shown in other embodiments). The processor 1020 loads each of these program modules onto the memory 1030 and executes them, thereby realizing each function corresponding to the program module. The storage device 1040 may also function as a device identification information storage unit 140, a product identification information storage unit 150, and a product information storage unit 160.

[0039] The input / output interface 1050 is an interface for connecting the management device 10 to various input / output devices.

[0040] The network interface 1060 is an interface for connecting the management device 10 to a network. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The network interface 1060 may be connected to the network by wireless connection or by wired connection. The management device 10 communicates with the display device 20 via the network interface 1060.

[0041] 9 is a flowchart showing an example of processing performed by the display processing unit 130 of the management device 10. The display processing unit 130 performs the processing shown in this figure for each of a plurality of products, that is, for each of a plurality of product identification information.

[0042] The display processing unit 130 acquires the product identification information (step S10), and then acquires the product information corresponding to the product identification information from the product information storage unit 160 (step S20). Next, the display processing unit 130 acquires the rewritable identification information corresponding to the product identification information acquired in step S10 from the product identification information storage unit 150 (step S30). Then, the display processing unit 130 transmits this rewritable identification information together with the product information acquired in step S20 to the multiple display devices 20 (step S40).

[0043] When the display device 20 receives the rewritable identification information stored in the display device 20, it stores the product information transmitted together with the rewritable identification information. If the display device 20 has already stored product information, it updates the old product information with the newly received product information. Then, the display device 20 displays the stored product information.

[0044] 10 is a flowchart showing an example of processing performed by the first update unit 110 of the management device 10. The processing shown in this drawing is performed when one of the display devices 20 attached to the display processing unit 130 is replaced with another display device 20.

[0045] First, a person managing the display devices 20 removes the display device 20 to be replaced (hereinafter referred to as the first display device 20) from the product shelf 30, and prepares another display device 20 (hereinafter referred to as the second display device 20) to be used in place of the first display device 20. Then, the first update unit 110 acquires from the first display device 20 the non-rewritable identification information stored in the display device 20 (hereinafter referred to as the first non-rewritable identification information), and acquires from the second display device 20 the non-rewritable identification information stored in the display device 20 (hereinafter referred to as the second non-rewritable identification information) (step S110).

[0046] Next, the first updating section 110 identifies rewritable identification information that corresponds to the first non-rewritable identification information in the device identification information storage section 140 (step S120).

[0047] Next, the first updating unit 110 updates the device identification information storage unit 140 (step S130). Specifically, the first updating unit 110 changes the non-rewritable identification information corresponding to the rewritable identification information identified in step S120 from the first non-rewritable identification information to the second non-rewritable identification information. For example, the first updating unit 110 erases the rewritable identification information corresponding to the first non-rewritable identification information from the device identification information storage unit 140, and stores this rewritable identification information in the device identification information storage unit 140 in association with the second non-rewritable identification information.

[0048] Furthermore, the rewritable identification information stored in the first display device 20 is erased. Then, this rewritable identification information is written to the second display device 20.

[0049] As described above, according to this embodiment, non-rewritable identification information is assigned to the display device 20. Then, the status information of the display device 20 is stored in the device identification information storage unit 140 in association with the non-rewritable identification information. Therefore, even if the rewritable identification information assigned to the display device 20 is changed, the status information of the display device 20 can continue to be managed.

[0050] Furthermore, when changing the display device 20 corresponding to a product, it is not necessary to update the product identification information storage unit 150, but instead it is sufficient to update the device identification information storage unit 140. This makes it easy to update the association between the display device and the product corresponding to that display device.

[0051] Furthermore, when the product identification information storage unit 150 is at least a part of a product master in a store computer, it is better to update the product identification information storage unit 150 less frequently. According to this embodiment, as described above, when changing the display device 20 corresponding to a product, there is no need to update the product identification information storage unit 150, and therefore the product identification information storage unit 150 is updated less frequently.

[0052] Second Embodiment 11 is a diagram showing an example of the functional configuration of the management device 10 according to the present embodiment. The management device 10 according to the present embodiment has the same configuration as the management device 10 according to the first embodiment, except that the management device 10 has a third update unit 170.

[0053] When the first updating unit 110 updates the device identification information storage unit 140, that is, when the display device 20 corresponding to a certain product is changed, the third updating unit 170 performs a process for updating the rewritable identification information stored in the display device 20 to be updated. For example, the third updating unit 170 performs a process for erasing the rewritable identification information stored in the first display device 20 described with reference to FIG. 10, and also performs a process for writing the rewritable identification information in the second display device 20. As an example, the third updating unit 170 transmits an instruction to erase the rewritable identification information of the first display device 20 to the display device 20 via the wireless communication unit. In addition, the third updating unit 170 transmits the non-rewritable identification information of the second display device 20 together with the rewritable identification information and an instruction to write the rewritable identification information to the display device 20.

[0054] According to this embodiment, when the display device 20 corresponding to a certain product is changed, the rewritable identification information stored in the display device 20 can be easily updated.

[0055] (Third embodiment) 12 is a diagram showing an example of the functional configuration of the management device 10 according to the present embodiment. The management device 10 according to the present embodiment has the same configuration as the management device 10 according to the second embodiment, except that it has an update information acquisition unit 180.

[0056] The update information acquisition unit 180 communicates with the first display device 20 and the second display device 20, and updates the rewritable identification information stored therein.

[0057] 13 is a diagram showing an example of the functional configuration of the update information acquisition unit 180. The update information acquisition unit 180 includes a first placement area 182, a second placement area 184, a first communication unit 186, and a second communication unit 188.

[0058] The first mounting area 182 is an area where a display device 20 having unrewritable identification information before the update, i.e., the first display device 20, is placed. The second mounting area 184 is an area where a display device 20 having unrewritable identification information after the update, i.e., the second display device 20, is placed. The manager of the display devices 20 places the first display device 20 in the first mounting area 182 and places the second display device 20 in the second mounting area 184.

[0059] The first communication unit 186 communicates with the first display device 20 placed in the first placement area 182, and the second communication unit 188 communicates with the second display device 20 placed in the second placement area 184. The third update unit 170 then erases the rewritable identification information stored in the first display device 20 via the first communication unit 186, and writes this rewritable identification information to the second display device 20 via the second communication unit 188.

[0060] In addition, between the first mounting area 182 and the first communication unit 186 and the second mounting area 184 and the second communication unit 188, a radio wave shielding member for blocking radio waves may be provided.

[0061] According to this embodiment, the rewritable identification information stored in the display device 20 can be updated more easily.

[0062] Although the embodiments of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than those described above can also be adopted.

[0063] In addition, in the flowcharts used in the above description, multiple steps (processes) are described in order, but the order of execution of the steps performed in each embodiment is not limited to the order described. In each embodiment, the order of the steps shown in the figures can be changed to the extent that the content is not affected. In addition, the above-mentioned embodiments can be combined to the extent that the content is not contradictory.

[0064] In each of the above-described embodiments, the display device 20 does not have to store rewritable identification information. In this case, in communication between the display device 20 and the management device 10, non-rewritable identification information is used instead of the rewritable identification information.
