It should be noted that the second product information does not need to be the character information “Price Reducedl” and may be other information for promoting the sales of the product P, such as the character information “On Sale!” or “Just Made”. In a case where the antenna 51 has received a command instructing to change what is stored in the memory 60 and what is displayed on the display unit 41-and particularly to delete the display of the second product information from the display unit 41-the NFC chip 52 10 10 15 20 25 30 changes What is stored in the memory 60 by deleting the second product information (here, the image information G2) from the memory 60. In a case Where the second communication unit 50 has received a command instructing to change What is stored in the memory 60 and What is displayed on the display unit 41, the NFC chip 52 outputs to the control unit 44 a signal inforrning the control unit 44 that the NFC chip 52 has received the command.
In a case Where the antenna 51 has received a command requesting the electronic shelf label 40 to transmit information to the handy terminal 70, the NFC chip 52 reads from the memory 60 the information requested to be transmitted. The information requested to be transmitted to the handy terminal 70 is, for example, the sales volume and the inventory quantity of the product P. The NFC chip 52 transmits by near field communication via the antenna 51 to the handy terminal 70 the information read from the memory 60. Due to this configuration, the handy terminal 70 can directly read the necessary information from the electronic shelf label 40 by near field communication Without communicating With the server 10 through the network, and the Worker carrying the handy terminal 70 can acquire the necessary information with good responsiveness. (2-1-4) Memory The memory 60 is included in the NFC chip 52 of the second communication unit 50.
The memory 60 is connected to the ?rst communication unit 42 and the second communication unit 50. It should be noted that “the memory 60 is connected to the first communication unit 42” is meant satisfying at least one of the conditions that the information received by the first communication unit 42 can be Written to the memory 60 or that the information read from the memory 60 can be transmitted from the ?rst communication unit 42. Furthermore, “the memory 60 is connected to the second communication unit 50” is meant satisfying at least one of the conditions that the information received by the second communication unit 50 can be Written to the memory 60 or that the information read from the memory 60 can be transmitted from the second communication unit 50.
Here, the memory 60 stores the ?rst product information (the product name, the unit sales price, the sales price, the barcode, the sales volume, and the inventory quantity and the like of the product P) received by the first communication unit 42. It should be noted that, in relation to the product name, the unit sales price, the sales price, and the barcode of the product P, the image information G1 (see FIG. 3) of these pieces of information is stored in the memory 60, and in relation to the sales volume and the inventory quantity of the product P, the numerical value information of these pieces of information is stored in the memory 60.
Furthermore, the memory 60 stores the second product information (the characters “Price 11 10 15 20 25 30 Reduced!”) received by the second communication unit 50. The second product information is stored in the memory 60 as the image information G2 (see FIG. 3). (2-1-5) Control Unit The control unit 44 is mainly configured by a CPU and a memory (not shown in the drawings) and the like. The control unit 44 is electrically connected to the display unit 4l, the ?rst communication unit 42, the second communication unit 50, the memory 60, and the battery 45 (see FIG. 5).
The memory of the control unit 44 stores a program to be executed by the CPU of the control unit 44 and the device ID that is the unique identifier of the electronic shelf label 40.
The control unit 44 controls each element of the electronic shelf label 40 by executing the program stored in the memory of the control unit 44. Specifically, the control unit 44 performs the following control.
For example, when the first communication unit 42 receives a command from the access points 30 and the received command is input from the first communication unit 42 to the control unit 44, the control unit 44 deterrnines whether or not it (the electronic shelf label 40 having that control unit 44) is the intended recipient of that command. Speci?cally, the control unit 44 compares the device ID attached to the command and the unique device ID stored in the memory of the control unit 44, and in a case where these match, the control unit 44 judges that it is the intended recipient of the command. In a case where the control unit 44 has judged that it is the intended recipient of the command, the control unit 44 stores in the memory 60 the first product information included in the command. Additionally, in a case where the command is a instruction to change What is displayed on the display unit 41 (the image including the product name, the sales price, the unit sales price, and the barcode of the product P), the control unit 44 controls the display unit 4l so that the display unit 41 displays the image information Gl including the product name, the sales price, the unit sales price, and the barcode of the product P which is newly stored in the memory 60. Furthermore, in a case where the control unit 44 has judged that it is the intended recipient of the command, the control unit 44 controls the ?rst communication unit 42 so that the first communication unit 42 transmits an acknowledgement signal to the server 10.
Furthermore, for example, in a case where the second communication unit 50 has received a command instructing to change what is stored in the memory 60 and what is displayed on the display unit 4l and the NFC chip 52 has input to the control unit 44 a signal informing the control unit 44 about this, the control unit 44 controls the display unit 41 so that what is displayed on the display unit 4l is changed. Specifically, for example, if the l2 10 15 20 25 30 command instructs the display unit 41 to display the image information G2 of the second product information (the character information “Price Reduced!”), the control unit 44 controls the display unit 41 so that the image information G2 stored in the memory 60 will be additionally displayed as shown in FIG. 3 on the display unit 41 which does not currently display the image information G2 as shown in FIG. 4. Furthermore, for example, if the command is an instruction to delete the display of the image information G2 from the display unit 41, the control unit 44 controls the display unit 41 so that the image information G2 will be deleted as shown in FIG. 4 from the display unit 41 in a state that the image information G2 is displayed as shown in FIG. 3. (2-1-6) Battery The battery 45 is configured to supply drive power to the display unit 41, the ?rst communication unit 42, and the control unit 44 of the electronic shelf label 40. The second communication unit 50 is configured to receive power by contactless power transmission from the handy terminal 70 and does not receive power from the battery 45. The memory 60 is configured to receive power from the battery 45 when data is written to and read from the memory 60 by the ?rst communication unit 42 and to receive power from the handy terminal 70 when data is written to and read from the memory 60 by the second communication unit 50. (2-2) Server The server 10 is a general computer that centrally manages information about the plural products P handled in the store. The server 10 transmits commands including the first product information to the electronic shelf labels 40 via the access points 30.
The server 10 mainly has a server communication unit 11, a server display unit 12, a server input unit 13, a server storage unit 14, and a server control unit 15 (see FIG. 6). (2-2-1) Server Communication Unit The server communication unit 11 is a communication interface for enabling the server 10 to communicate with the access points 30 and the handy terrninals 70.
Furthermore, the server 10 is configured in such a way that it can also communicate, via the server communication unit 11, for example, with a server and a store controller of a POS system installed in the store where the electronic shelf label system 1 is installed. Commands that have been sent from the server communication unit 11 to the access points 30 are transmitted from the access points 30 to the electronic shelf labels 40. (2-2-2) Server Display Unit The server display unit 12 is a liquid crystal display. The server display unit 12 can 13 10 15 20 25 30 display various types of information relating to the electronic shelf label system 1. (2-2-3) Server Input Unit The server input unit 13 includes a mouse and a keyboard. Various types of commands and Various types of information With respect to the server 10 can be input via the server input unit 13. (2-2-4) Server Storage Unit The server storage unit 14 is configured by a ROM, a RAM, a hard disk, and the like.
Various types of programs executed by the server control unit 15 described later are stored in the server storage unit 14. Furthermore, various types of information are stored in the server storage unit 14. The information stored in the server storage unit 14 includes a product master table 14a and an electronic shelf label master table l4b (see FIG. 5). (2-2-4-1) Product Master Table The product master table 14a contains information relating to the products P handled by the electronic shelf label system 1. The information relating to the products P includes, for example, product names, sales prices, unit sales prices, product barcodes, sales volumes, and inventory quantities. In the product master table 14a, the information relating to the products is stored according to the product IDs (barcode information) of the products P. The contents of the product master table 14a are updated When the server communication unit ll receives information from an outside device (e. g., the POS system not shown in the drawings) or When the server input unit 13 receives input of information. (2-2-4-2) Electronic Shelf Label Master Table The electronic shelf label master table l4b contains information that links the device IDs for identifying the electronic shelf labels 40 and the product IDs of the products P to each other. Because the device IDs and the product IDs are linked to each other and stored in the electronic shelf label master table l4b, the electronic shelf labels 40 and the products P corresponding to the electronic shelf labels 40 are linked to each other. In other words, because the device IDs and the product IDs are linked to each other and stored in the electronic shelf label master table l4b, the product information of the product P to be displayed on a given electronic shelf label 40 is identi?ed. The device IDs and the product IDs are linked to each other by the linking Work performed by the Worker using the handy terminal 70. (2-2-5) Server Control Unit The server control unit 15 controls each element of the server 10 by executing the programs stored in the server storage unit 14. Specifically, the server control unit 15 14 10 15 20 25 80 performs the following control.
For example, as described later, when the server communication unit 11 receives the device ID of an electronic shelf label and the product ID of a product P, transmitted by the handy terminal 70, which are to be linked to each other, the server control unit 15 links the device ID and the product ID to each other and stores them in the electronic shelf label master table 14b.
Furthermore, for example, when the electronic shelf label system 1 starts up or when it is necessary to change the content of what is stored in and/or the content of what is displayed on the electronic shelf labels 40, the server control unit 15 generates a command including the first product information and transmits the command via the access points 30 to the electronic shelf labels 40. By “when it is necessary to change what is displayed on the electronic shelf labels 40” is meant, for example, when the contents of the product master table l4a or the electronic shelf label master table l4b have been updated.
When the server control unit 15 transmits to an electronic shelf label 40 a command instructing to change what is stored in the memory 60 and what is displayed on the display unit 41, the server control unit 15 performs the following processing.
First, the server control unit 15, in regard to a product P for which displayed content on the electronic shelf label 40 is to be changed, generates, by referencing the product master table 14a, image information (e.g., the image information Gl (see FIG. 3) including the product name, the sales price, the unit sales price, and the barcode of the product P) to be transmitted to the electronic shelf label 40. Furthermore, the server control unit 15 acquires, as a transmission destination identifier, the device ID of the electronic shelf label 40 linked to the product P for which displayed content on the electronic shelf label 40 is to be changed by referencing the electronic shelf label master table 14b.
Next, the server control unit 15 generates a command including the image information G1, to which the acquired transmission destination identifier (the device ID of the electronic shelf label 40 to which the command is to be transmitted) is added. Moreover, the server control unit 15 transmits the generated command to the access points 30. The access points 30 which have received the command transmit the command by radio wave to the electronic shelf label 40.
When the server control unit 15 transmits to an electronic shelf label 40 a command instructing the electronic shelf label 40 to change only what is stored in the memory 60, the server control unit 15 perforrns the following processing.
First, the server control unit 15, in regard to a product P for which stored content on 15 10 15 20 25 80 the electronic shelf label 40 is to be changed, reads the information that is to be changed (e. g., the inventory quantity of the product P) by referencing the product master table l4a.
Furtherrnore, the server control unit 15 acquires, as a transmission destination identifier, the device 1D of the electronic shelf label 40 linked to the product P for Which displyaed content on the electronic shelf label 40 is to be changed by referencing the electronic shelf label master table l4b.
Next, the server control unit 15 generates a command including the numerical value information of, for example, the inventory quantity of the product P, to Which the acquired transmission destination identifier (the device ID of the electronic shelf label 40 to Which the command is to be transmitted) is added. Moreover, the server control unit 15 transmits the generated command to the access points 30. The access points 30 Which have received the command transmit the command by radio Wave to the electronic shelf label 40.
As mentioned above, When the electronic shelf label 40 receives the delivery data intended for it, the electronic shelf label 40 transmits an acknowledgement signal to the access points 30. The access points 30 Which have received the acknowledgement signal transmit the acknowledgement signal via the network 2 to the server communication unit ll of the server 10. When the server communication unit 11 receives the acknowledgement signal after having transmitted the command, the server control unit 15 judges that it has success?ally communicated With the electronic shelf label 40 and ends the processing for transmitting the product information to the electronic shelf label 40. On the other hand, in a case Where, for some reason, the access points 30 do not receive the acknowledgement signal, the server control unit 15 retransmits the delivery data. (3) Characteristics (3-1) The electronic shelf label system 1 as an example of a Wireless display system pertaining to the present embodiment is equipped With the server 10, the electronic shelf labels 40 as an example of plural Wireless display modules, and the access points 30 as an example of communication devices. The electronic shelf label system 1 communicates with the handy terminal 70 as an example of a portable terminal. The server 10 stores the first product information (an example of first article information) relating to the plural products P (an example of articles). The electronic shelf labels 40 are arranged corresponding to the plural products P respectively. The access points 30 transmit to each of the electronic shelf labels 40 the first product information, stored in the server 10, related to the products P corresponding to that electronic shelf labels 40. Each of the electronic shelf labels 40 has the 16 10 15 20 25 30 display unit 41, the ?rst communication unit 42, the second communication unit 50, and the memory 60 as an example of a storage unit. The display unit 41 displays information relating to the product P corresponding to that electronic shelf label 40. The ?rst communication unit 42 receives the first product information from the access points 30. The second communication unit 50 communicates With the handy terminal 70 by near field communication. The memory 60 is connected to the ?rst communication unit 42 and the second communication unit 50. The memory 60 stores at least the first product information.
Here, each of the electronic shelf labels 40 has, in addition to the ?rst communication unit 42 receiving information from the server 10, the second communication unit 50 communicating With the handy terminal 70 by near field communication, and the ?rst communication unit 42 and the second communication unit 50 are connected to the shared memory 60. Due to this configuration, information can be Written from the handy terminal 70 to the memory 60 and thereby displayed content on the electronic shelf label 40 can be changed. As a result, displayed content on the electronic shelf label 40 can be changed, as occasion may demand, at the location Where the electronic shelf label 40 is installed.
Furthermore, here, the information stored in the memory 60 can be directly read by the handy terminal 70 via near field communication. For that reason, the handy terminal 70 can acquire the information With good responsiveness at the location Where the electronic shelf label 40 is installed compared to a case Where the handy terminal 70 acquires the information relating to the product P corresponding to the electronic shelf label 40 via the network. (3-2) In the electronic shelf label system l pertaining to the present embodiment, the second communication unit 50 receives information transmitted from the handy terminal 70 as the second product information (an example of second article information) relating to the product P corresponding to the electronic shelf label 40 having that second communication unit 50.
The memory 60 stores the second product information received by the second communication unit 50. The display unit 41 displays the second product information stored in the memory 60 as information relating to the product P corresponding to the electronic shelf label 40 having that display unit 41.
Here, as the second product information transmitted from the handy terminal 70 is displayed on the electronic shelf label 40, displayed content on the electronic shelf label 40 can be changed, as occasion may demand, at the location Where the electronic shelf label 40 is installed. 17 10 15 20 25 30 (3-3) In the electronic shelf label system 1 pertaining to the present embodiment, the second communication unit 50 transmits by near field communication to the handy terrninal 70 the information stored in the memory 60.
Here, as the information stored in the memory 60 is transmitted by near field communication to the handy terminal 70, the information can be acquired at the location where the electronic shelf label 40 is installed with better responsiveness compared to a case where the handy terminal 70 acquires the information relating to the product P corresponding to the electronic shelf label 40 via the network. (4) Example Modi?cations Example modifications of the first embodiment will be described below. It should be noted that multiple example modi?cations may also be combined to the extent that they are consistent with each other. (4-1) Example Modi?cation IA In the electronic shelf label system 1 pertaining to the above embodiment, the electronic shelf labels 40 communicate with the access points 30 by radio Wave, but the electronic shelf label system 1 is not limited to this. For example, the electronic shelf label system 1 may also be configured in such a way that the electronic shelf labels and the communication devices transmitting to the electronic shelf labels the first product information stored in the server 10 communicate with each other using infrared. (4-2) Example Modification IB In the electronic shelf label system 1 pertaining to the above embodiment, the second communication unit 50 receives from the handy terminal 70 a command to display on the display unit 41 , or delete from the display unit 41, the image information G2 of the characters “Price Reduced!”, but the electronic shelf label system 1 is not limited to this. For example, the second communication unit 50 may also receive from the handy terminal 70 a command (a command including the image information of the sales price) relating to an update of the sales price (an update of the image information of the sales price).
In a case where the electronic shelf label system 1 is configured in this Way, there is a risk that the sales price stored in the server 10 and the sales price displayed on the electronic shelf label 40 become inconsistent. It is therefore preferred that processing to achieve consistency between these is performed.
For example, when a command relating to an update of the sales price is transmitted to the second communication unit 50, the barcode of the product P whose sales price is to be 18 10 15 20 25 80 updated may be scanned by the handy terminal 70, and the barcode of the product P and the updated sales price may be transmitted from the handy terminal 70 to the server 10 via a network not shown in the drawings. By updating the product master table l4a based on the received information in the server 10, a consistency between the sales price being stored in the server 10 and the sales price displayed on the electronic shelf label 40 can be achieved.
Furthermore, for example, when a command relating to an update of the sales price is transmitted to the second communication unit 50, the control unit 44 of the electronic shelf label 40 may control the ?rst communication unit 42 so that the updated sales price stored in the memory 60 is transmitted to the access points 30 together with the device ID stored in the memory 60. That is to say, the first communication unit 42 may be configured to transmit to the access points 30 the sales price, that serves as the second product information, stored in the memory 60. The server 10 may store in the product master table l4a the information transmitted from the first communication unit 42 to the access points 30 as information relating to the product P corresponding to the electronic shelf label 40 having the ?rst communication unit 42 that transmitted that information. When the electronic shelf label system l is configured in this way, consistency between the sales price being stored in the server 10 and the sales price displayed on the electronic shelf display 40 can be achieved. By achieving consistency between the local information stored in the electronic shelf label 40 and the information stored in the server 10, the information can be centrally managed in the server 10 while enabling to change the displayed content on the electronic shelf label 40 as occasion may demand. (4-3) Example Modi?cation IC In the above embodiment, the handy terminal 70 serves as example of a portable terminal, but the portable terminal is not limited to this. For example, the portable terminal communicating by near ?eld communication with the second communication unit 50 may be a smart phone or a tablet computer separate from the handy terminal 70 used in the linking work. This kind of portable terminal may also be configured to exhibit the ?inctions described in the above embodiment by executing application software for communicating with the second communication unit 50.
It should be noted that, in a case where the portable terminal is configured in this way, the portable tenninal does not have to be configured in such a way that it can communicate with the server 10. Even if a portable terminal is not connected via a network to the server 10, the portable terminal can, using near field communication, acquire from the electronic shelf label 40 the various types of information being stored in the memory 60 with good 19 10 15 20 25 30 responsiveness. Furthermore, even if a portable terminal is not connected Via a network to the server 10, the portable terminal can, using near field communication, change the information being stored in the memory 60 and further update the information displayed on the display unit 41 of the electronic shelf label 40. (4-4) Example Modi?cation lD In the above embodiment, when the linking work has been performed by the handy terminal 70, a command including the first product information is transmitted from the server 10 via the access points 30 to the electronic shelf label 40, but the electronic shelf label system 1 is not limited to this.
For example, the electronic shelf label system 1 may also be configured in such a way that, when the linking work has been performed by the handy terminal 70, a command including the first product information is transmitted from the server 10 to the handy terminal 70 and a command including the first product information is transmitted by near field communication from the handy terminal 70 to the electronic shelf label 40.
Ordinarily, in a case where a command is transmitted from the server 10 via the access points 30 to an electronic shelf label 40, the command is also transmitted to the electronic shelf labels 40 that are not the intended recipient of that command. For that reason, the electronic shelf labels 40 that are not the intended recipient of the command also need to perform the processing of first receiving the command and then deterrnining whether or not they are the intended recipient of the command, and the power of their batteries 45 is needlessly consumed. In contrast to this, by using near field communication for the communication during the linking work, commands are not transmitted to the electronic shelf labels 40 that are not the intended target of the linking work, so unnecessary power consumption of the batteries 45 can be controlled. (4-5) Example Modi?cation lE In the above embodiment, when the linking work is performed with the handy terminal 70, the handy terminal 70 acquires the device ID of the electronic shelf label 40 by scanning the barcode assigned to the electronic shelf label 40, but the handy terminal 70 is not limited to this. For example, the handy terminal may be con?gured to acquire the device ID of the electronic shelf label 40 by reading, by near field communication, the device ID stored in the memory 60. (4-6) Example Modi?cation lF In the above embodiment, an electronic shelf label system has been described as an example of the wireless display system pertaining to the present invention, but the wireless 20 10 15 20 25 30 display system pertaining to the present invention is not limited to an electronic shelf label system installed in a store or the like.
For example, the Wireless display system may also be utilized in a hospital.
Specifically, in a hospital, there are cases Where management is performed in Which drugs (injectable drugs and orally administered drugs) are prepared and put into containers according to patient in a phannacy or the like, and those containers are carried to hospital rooms and the like. In such cases, the Wireless display system may be configured in such a Way that wireless display modules (wireless display modules having the same device configuration as the electronic shelf labels 40 pertaining to the above embodiment) are attached to the plural containers (an example of articles) respectively, and each of the Wireless display modules stores, in the memory connected to the first communication unit and the second communication unit, information (an example of first article information) relating to the containers and transmitted from the server. The information relating to the containers is, for example, the names of the patients Who are to use the drugs (that should be) in those containers and a list of the names of the drugs (that should be) in those containers and the like.
In the Wireless display system used in a hospital, for example, When a nurse or the like has checked to see that the drug displayed on a Wireless display module and the drug in the container match, the nurse or the like uses a portable terminal able to communicate With the second communication unit of the Wireless display module to transmit a command for causing image information of the character information “Check Completed” (an example of second article information) to be displayed on the Wireless display module attached to the container for Which the check has been completed. The second communication unit of the Wireless display module is configured to receive the command including the image information of the character information “Check Completed” transmitted from the portable terminal, and the memory is configured to store the image information of the character information “Check Completed” received by the second communication unit. The display unit of the Wireless display module is configured to display, as information relating to the container corresponding to the Wireless display module having that display unit, the image information of the character information “Check Completed” stored in the memory.
Furthermore, the Wireless display system used in a hospital is configured in such a Way that, for example, after the nurse or the like has finished carrying the drug in the container to a hospital room, a treatment room or the like, the nurse or the like uses a portable terminal able to communicate With a near field communication unit of the Wireless display 21 10 15 20 25 80 module to instruct the Wireless display module attached to the container the nurse has finished carrying to, for example, erase (change) the ?rst article information (e.g., the patient name) displayed on the display unit, and the Wireless display module that has received the instruction erases (changes) the first article information stored in the memory and erases (changes) the display of the first article information on the display unit. In this case, it is preferred that the Wireless display system be configured in such a Way that the Wireless display module or the portable terminal inforrns the server the change of the displayed content on the Wireless display module so that the server grasps that there has been a change to the displayed content on the Wireless display module.
Furthermore, the Wireless display system used in a hospital may be configured in such a Way that, for example, information such as directions for using the drug in the container is also transmitted via the access points from the server to the Wireless display module as the first article information relating to the container. Additionally, the second communication unit of the Wireless display module may be configured in such a Way that it can transmit, by near field communication, the information-such as the directions for using the drug-stored in the memory to the portable terminal that is able to communicate With the second communication unit of the Wireless display module and Which the nurse or the like has.
Furthermore, for example, the Wireless display system may be utilized in a Warehouse or the like. Speci?cally, in a case Where objects-to-be-transported are put into transport containers according to their transport destination and are stored and managed in the Warehouse, the Wireless display system may be configured in such a Way that Wireless display modules (Wireless display modules having the same device configuration as the electronic shelf labels 40 pertaining to the above embodiment) are attached to the plural transport containers (an example of articles) respectively, and each of the Wireless display modules stores, in the memory connected to the ?rst communication unit and the second communication unit, information (an example of first article information) relating to the transport containers and transmitted from the server. The information relating to the transport containers is, for example, the transport destinations of the objects-to-be-transported in those transport containers and the names, numerical quantities, and so forth of the objects-to-be- transported in the transport containers.
In the Wireless display system used in a Warehouse, for example, When a Worker or the like has ?nished inspecting the object-to-be-transported in a transport container, the Worker or the like uses a portable terminal able to communicate With the second communication unit of the Wireless display module to transmit a command for causing image 22 10 15 20 25 30 information of the character information “Inspection Completed” (an example of second article information) to be displayed on the Wireless display module attached to the transport container for Which the inspection has been completed. The second communication unit of the Wireless display module is configured to receive the command including the image information of the character information “lnspection Completed” transmitted from the portable terminal, and the memory is configured to store the image information of the character information “Inspection Completed” received by the second communication unit.
The display unit of the Wireless display module is configured to display, as information relating to the transport container corresponding to the Wireless display module having that display unit, the image information of the character information “lnspection Completed” stored in the memory.
Furthermore, the Wireless display system used in a Warehouse may be con?gured in such a Way that, as the ?rst article information relating to the transport container, for example, information such as the Characteristics of the object-to-be-transported in the container is also transmitted via the access points from the server to the Wireless display module. Additionally, the second communication unit of the Wireless display module may be con?gured in such a Way that it can transmit, by near field communication, the Characteristics of the object-to-be-transported stored in the memory to the portable terminal that is able to communicate With the second communication unit of the Wireless display module, Which the Worker or the like has.
Also in the Wireless display systems utilized in a hospital and a Warehouse described above, What is displayed on the Wireless display module can be changed, as occasion may demand, at the location Where the Wireless display module is installed. Furthermore, in the Wireless display systems described above, the information can be acquired With better responsiveness at the location Where the Wireless display module is installed compared to a case Where the information relating to the container/transport container corresponding to the Wireless display module (e.g., information such as directions for using the drug in the container, information such as the characteristics of the object-to-be-transported in the container) is acquired via a network.
Second Embodiment An electronic shelf label system l0l pertaining to a second embodiment of the present invention Will be described below.
The electronic shelf label system l0l pertaining to the second embodiment is an example of the Wireless display system pertaining to the present invention. The electronic 23 10 15 20 25 80 shelf label system 101 has many points in common With the electronic shelf label system 1 pertaining to the ?rst embodiment, so mainly its points of difference will be described.
It should be noted that, in the second embodiment, elements assigned reference signs that are the same as those assigned to the elements pertaining to the ?rst embodiment have the same configurations/?dnctions as those elements pertaining to the first embodiment. (1) Overall Configuration FIG. 7 is an overall schematic diagram of the electronic shelf label system 101 pertaining to the second embodiment.
As shown in FIG. 7, the electronic shelf label system 101 is mainly provided with a server 110, electronic shelf labels 140 as an example of plural wireless display modules, and plural access points 30. The server 110 and the electronic shelf labels 140 are partially different from the server 10 and the electronic shelf labels 40 pertaining to the ?rst embodiment in the content of the stored information and the executed processing, but are same with the server 10 and the electronic shelf labels 40 pertaining to the ?rst embodiment in device configurations. With regard to the server 110 and the electronic shelf labels 140, the differences from the server 10 and the electronic shelf labels 40 pertaining to the ?rst embodiment will be described in the following detailed description. As regards the access points 30, they are the same as those of the first embodiment so description thereof will be omitted.
It should be noted that, in contrast to the ?rst embodiment, the electronic shelf label system 101 is configured in such a way that it can communicate with a smart phone 170 carried by a store visitor (a potential buyer of products P that are an example of articles). The smart phone 170 is an example of a portable terminal. That is to say, the smart phone 170 has a near field communication function. The smart phone 170 is a RF tag reader/writer that can communicate by near ?eld communication with second communication units 150 (RF tags) of the electronic shelf labels 40.
Application software that enables the smart phone 170 to communicate with the second communication units 150 of the electronic shelf labels 140 is stored in the smart phone 170. The smart phone 170 is configured in such a way that it can transmit information to and receive information from the electronic shelf labels 140 and transmit commands to the electronic shelf labels 140 as described below as a result of a CPU of the smart phone 170 executing the application software.
The smart phone 170 is configured in such a way that, for example, it can transmit to the electronic shelf labels 140 information representing interest in the products P. That is to 24 10 15 20 25 30 say, a potential buyer of a given product P can use the smart phone 170 to transmit to the second communication unit 150 information (hereinafter called third product information) representing interest in the product P corresponding to the electronic shelf label 140 having that second communication unit 150. The third product information is an example of third article information. The third product information is, for example, information expressing the fact that the potential buyer likes the product P (expressing a “like”). The third product information is, for example, transmitted to the second communication unit 150 when the potential buyer perforrns on the smart phone 170 an operation expressing the fact that the potential buyer has an interest in a given product P (e.g., pressing a “like” button on the screen of the smart phone 170) and brings the smart phone 170 closer to the electronic shelf label 40.
Furthermore, in accordance with the operation performed by the potential buyer of the product P, the smart phone 170 generates a command for causing the information relating to the product P and being stored in the electronic shelf label 140 to be transmitted to the smart phone 170. The smart phone 170 then transmits the generated command to the second communication unit 150 of the electronic shelf label 140. Here, the information relating to the product P that the smart phone 170 requests the electronic shelf label 140 to transmit will be called fourth product information. The fourth product information includes, for example, allergy information about the product P, information relating to the place of production/producer of the product P, information relating to days when the product P will be on sale, and information about recipes using the product P. For example, by selecting on the smart phone 170 an item about which the potential buyer wants to acquire information, the smart phone 170 generates a command requesting that the fourth product information be transmitted in regard to the selected item. Then, by bringing the smart phone 170 closer to the electronic shelf label 140, the command is transmitted to the second communication unit 150 of that electronic shelf label 140. (2) Detailed Configuration Regarding the electronic shelf labels 140 and the server 110 of the electronic shelf label system 101, the differences between these and counterparts of the first embodiment will be mainly described in detail below. (2-1) Electronic Shelf Labels The information relating to the products P and displayed on the electronic shelf labels 140 includes the product names, the sales prices, the unit sales prices, the product barcodes, and the number of “likes” (a count number representing the number of times that the third 25 10 15 20 25 30 product information has been received) (see FIG. 8). The number of “likes” is an example of a display of information based on the third product information. It should be noted that, in contrast to the electronic shelf labels 40 of the first embodiment, the electronic shelf labels 140 do not display the characters “Price Reducedl”.
Like in the first embodiment, each of the electronic shelf labels 140 mainly has the display unit 41, a ?rst communication unit 142, the second communication unit 150, a memory 160, a control unit 144, and the battery 45 (see FIG. 9). The display unit 41 and the battery 45 are the same as those of the ?rst embodiment. Here, the differences that the first communication unit 142, the second communication unit 150, the memory 160, and the control unit 144 have With respect to the first embodiment Will mainly be described. (2-1-1) First Communication Unit The first communication unit 142 is, in relation to its device configuration, the same as the first communication unit 42 of the first embodiment. The first communication unit 142 differs from the first communication unit 42 pertaining to the first embodiment in that the information relating to the product P and transmitted from the access points 30 to the first communication unit 142 (the information relating to the product P and received by the first communication unit 142) includes the fourth product information in addition to the ?rst product information such as the product name, the unit sales price, the sales price, and the product barcode of the product P. It should be noted that the fourth product information is information relating to the product P and transmitted to the smart phone 170 and, for example, includes allergy information about the product P, the place of production/producer of the product P, information relating to days When the product P Will be on sale, and information about recipes using the product P. In regard to other points, the ?rst communication unit 142 is the same as the first communication unit 42 of the first embodiment, so description Will be omitted here. (2-1-2) Second Communication Unit The second communication unit 150 is a passive RF tag that receives power by contactless power transmission from the smart phone 170. The second communication unit 150 communicates by near field communication With the smart phone 170.
The second communication unit 150 is, in relation to its device configuration, the same as the second communication unit 50 of the first embodiment. The second communication unit 150 is the same as the second communication unit 50 of the ?rst embodiment except that the information and commands transmitted from the portable terminal (here, the smart phone 170) to the second communication unit 150 are different. The 26 10 15 20 25 30 inforrnation/commands that the second communication unit 150 receives from the smart phone 170 and the actions of the NFC chip 52 When it receives the inforrnation/commands Will mainly be described below.
In a case Where the antenna 51 has received the third product inforrnation (an expression of a “like”) from the smart phone 170, the NF C chip 52 performs processing that increases by 1 the count number stored in the memory 60, Which represents the number of times that a “like” has been received. In other Words, the NFC chip 52 perforrns processing that updates the information based on the third product information and stored in the memory 60. In addition, the NFC chip 52 outputs to the control unit 44 a signal inforrning the control unit 44 that the NFC chip 52 has received the third product information.
In a case Where the antenna 51 has received a command requesting the electronic shelf label 140 to transmit information to the smart phone 170, the NFC chip 52 reads from the memory 160 the information requested to be transmitted. The information requested to be transmitted to the smart phone 170 is, for example, allergy information about the product P, information relating to the place of production/producer of the product P, information relating to days When the product P Will be on sale, and information about recipes using the product P. The NF C chip 52 transmits by near field communication via the antenna 51 to the smart phone 170 the information read from the memory 160. Because the second communication unit 150 is configured in this Way, the smart phone 170 can directly read the necessary information from the electronic shelf label 140 by near field communication Without communicating With the server 110 through the network, and the store visitor carrying the smart phone 170 can acquire the necessary information With good responsiveness. (2-1-3) Memory The memory 160 is included in the NFC chip 52 of the second communication unit 150. The memory 160 is, like in the ?rst embodiment, connected to the first communication unit 142 and the second communication unit 150. The information stored in the memory 160 differs from the information stored in the memory 60 of the ?rst embodiment as follows.
The memory 160 stores the fourth product information, in addition to the information, received by the first communication unit 142, described as the first product information in the first embodiment (e. g., the product name, the unit sales price, the sales price, and the product barcode of the product P). Furthermore, in contrast to the ?rst embodiment, the memory 160 does not store the second product information.
Rather, the memory 160 stores the information based on the third product information (the count number representing the 27 10 15 20 25 80 number of times that the third product inforrnation has been received by the second communication unit 150). The third product information is the information (an expression of a “like”) representing an interest in the product P and transmitted to the second communication unit 150 from the smart phone 170 of the potential buyer of the product P corresponding to the electronic shelf label 140 having that second communication unit 150. (2-1-4) Control Unit The control unit 144 is, in regard to its device configuration, the same as the control unit 44 of the first embodiment. Furthermore, the actions of the control unit 144 performed When the first communication unit 142 receives commands from the access points 30 are the same as the actions of the control unit 44 of the first embodiment, so description thereof Will be omitted.
When the control unit 144 receives from the second communication unit 150 the input of the signal informing the reception of the third product information, the control unit 144 controls the display unit 41 so as to change What is displayed on the display unit 41.
Specifically, the control unit 144 controls the display unit 41 in such a Way that the most recent count number, representing the number of times that the third product information has been received and Which is stored in the memory 160 as information based on the third product information, is displayed on the display unit 41 (see G3 in FIG. 8). (2-2) Server The server 110 is a general computer that centrally manages the information of the plural products P handled in the store. The configuration of the server 110 (see FIG. 10) is the same as the configuration of the server 10 pertaining to the ?rst embodiment. The server 110 is the same as the server 10 of the first embodiment except that: the fourth product information is included in the information relating to the products P and stored as a product master table 114a in the server storage unit 14; and the fourth product information is transmitted as needed from the server communication unit 11 via the access points 30 to the electronic shelf labels 140. Other description relating to the server 110 Will be omitted here. (3) Characteristics (3-1) The electronic shelf label system 101 as an example of a Wireless display system pertaining to the present embodiment is equipped With the server 110, the electronic shelf labels 140 as an example of plural Wireless display modules, and the access points 30 as an example of communication devices. The electronic shelf label system 101 communicates With the smart phone 170 as an example of a portable terminal. The server 110 stores the first 28 10 15 20 25 30 product information (an example of first article inforrnation) relating to the plural products P (an example of articles). The electronic shelf labels 140 are arranged corresponding to the plural products P. The access points 30 transmit to each of the electronic shelf labels 140 the first product information related to the products P corresponding to that electronic shelf label 140 and stored in the server 110. Each of the electronic shelf labels 140 has the display unit 41, the ?rst communication unit 142, the second communication unit 150, and the memory 160 as an example of a storage unit. The display unit 41 displays the information relating to the product P corresponding to that electronic shelf label 140. The first communication unit 142 receives the first product information from the access points 30. The second communication unit 150 communicates With the smart phone 170 by near field communication. The memory 160 is connected to the ?rst communication unit 142 and the second communication unit 150. The memory 160 stores at least the ?rst product information.
Here, each of the electronic shelf labels 140 has, in addition to the ?rst 1 10, communication unit 150 communicating With the smart phone 170 by near field communication unit 142 receiving information from the server the second communication, and the ?rst communication unit 142 and the second communication unit 150 are connected to the shared memory 160. Due to this configuration, information can be Written from the smart phone 170 to the memory 160 and thereby displayed content on the electronic shelf label 140 can be changed. As a result, displayed content on the electronic shelf label 140 can be changed, as occasion may demand, at the location Where the electronic shelf label 140 is installed.
Furthermore, here, the information stored in the memory 160 can be directly read using the smart phone 170 by near field communication, and a potential buyer (store visitor) can acquire the information relating to the product P at the location Where the electronic shelf label 140 is installed With good responsiveness. (3-2) In the electronic shelf label system 101 pertaining to the present embodiment, the products P are articles to be purchased by buyers. The second communication unit 150 receives, as the third product information relating to the product P corresponding to the electronic shelf label 140 having that second communication unit 150, information (an expression of a “like”) for representing interest in the product P Which is transmitted from the smart phone 170 of the potential buyer of the product P corresponding to the electronic shelf label 140 having that second communication unit 150.
The display unit 41 displays 29 10 15 20 25 80 information based on the third product information and stored in the memory 160-more specifically, the count number of the third product information, as information relating to the product P corresponding to the electronic shelf label 140 having that display unit 41.
Here, the electronic shelf labels 140 can display in real time which products P are drawing potential buyers” interest. Due to this configuration, the potential buyers can tell sellers which products draw his or her interest and leam which products draw other potential buyers” interest. Furthermore, the sellers can also easily leam the needs of the buyers. (3-3) In the electronic shelf label system 101 pertaining to the present embodiment, the second communication unit 150 transmits by near field communication to the smart phone 170 the information (in particular, here the fourth product information) stored in the memory 160.
Here, as the information stored in the memory 160 is transmitted by near field communication to the smart phone 170, the information can be acquired with better responsiveness at the location where the electronic shelf label 140 is installed compared to a case where the smart phone 170 acquires via a network the information relating to the product P corresponding to the electronic shelf label 140. (4) Example Modifications The contents of the first embodiment and the second embodiment may also be combined with each other to the extent that they are consistent with each other. For example, like in the case of the first embodiment, the electronic shelf label 140 may also be con?gured in such a way that the second product information (e.g., the characters “Price Reduced!”) is also displayed on the display unit 41 as a result of near field communication being performed with the portable terminal (e.g., the handy terminal 70). (4-1) Example Modi?cation 2A In the electronic shelf label system 101 pertaining to the above embodiment, the electronic shelf labels 140 communicate with the access points 30 by radio wave, but the electronic shelf label system 101 is not limited to this. For example, the electronic shelf label system 101 may be configured in such a way that the electronic shelf labels and the communication devices transmitting to the electronic shelf labels the first product information and the fourth product information stored in the server 110 communicate with each other using infrared. (4-2) Example Modification 2B In a case where the second communication unit 150 has received the third product 30 10 15 20 25 30 information, the control unit 144 may, in addition to updating so as to increase by 1 the count number stored in the memory 160 and representing the number of times that the third product information has been received, control the first communication unit 142 so as to transmit to the access points 30 the updated count number representing the number of times that the third product information has been received. Additionally, the server 110 may store, in the product master table l14a of the server storage unit 14, the count number representing the number of times that the third product information has been received and being transmitted from the first communication unit 142 to the access points 30, as information relating to the product P linked to the electronic shelf label 140 having the first communication unit 142 that transmitted the count number. Because of this, the information based on the third product information (the count number representing the number of times that the third product information has been received) is transmitted to and stored in the server 110. That is to say, here, the server 110 can centrally grasp Which products P draw potential buyers” interest.
Stocking of the products P and so forth can be performed based on the results. (4-3) Example Modification 2C In the above embodiment, the smart phone 170 is con?gured to directly acquire allergy information about the product P and so forth as the fourth product information from the electronic shelf label 140, but the electronic shelf label system 101 is not limited to this.
For example, the electronic shelf label system 101 may be configured in such a Way that, instead of the fourth product information itself, an Internet URL at Which the smart phone 170 can acquire the fourth product information is transmitted from the second communication unit 150 to the smart phone 170.
However, from the standpoint of responsiveness, it is preferred that the second communication unit 150 transmit directly utilizable information (information that the smart phone 170 does not need to acquire through the Intemet) by near ?eld communication to the smart phone 170.
INDUSTRIAL APPLICABILITY The Wireless display system pertaining to the present invention is useful as a Wireless display system in Which displayed content on Wireless display modules can be changed as occasion may demand.
