  Next, the flow of device information registration processing according to the second embodiment of the present invention will be described with reference to FIG. Here, it is assumed that the relay device 30 is an access point used in wireless LAN communication, and the information output device 10 operates as a slave in wireless LAN communication.

  First, the information output device 10 and the relay device 30 execute initial setting in order to perform wireless LAN communication (S11). The initial setting is, for example, that the information output apparatus 10 registers an SSID, an encryption key, and the like registered in advance in the relay apparatus 30. When the initial setting for performing wireless LAN communication is completed between the information output apparatus 10 and the relay apparatus 30, the relay apparatus 30 transmits dialog box information to the information output apparatus 10 (S12). When the wireless communication unit 12 receives the transmitted dialog box information, the information output device 10 displays a dialog box (S13). In step S13, the information output apparatus 10 displays the dialog box described in FIG.

  Next, the information output apparatus 10 receives an input of a device identifier from a user who operates the information output apparatus 10 (S14). That is, the user who operates the information output apparatus 10 selects a device identifier, which is information indicating the classification of the apparatus corresponding to the information output apparatus 10, from the dialog box shown in FIG. Next, the information output device 10 transmits the device identifier selected by the user to the relay device 30 (S15).

  Next, the relay device 30 stores the device identifier transmitted in step S15 in the device information storage unit 35 in association with the MAC address of the information output device 10 or the assigned IP address (S16).

  In step S14, the information output apparatus 10 regards that “other” is selected as the device identifier when the device identifier is not input even after a preset time has elapsed, in other words, when the device identifier is not selected. Also good. In this case, the information output apparatus 10 may transmit “Other” as the device identifier to the relay apparatus 30.

  Alternatively, if the relay device 30 does not receive the device identifier in step S15 even after a predetermined time has elapsed after transmitting the dialog box information in step S12, the relay device 30 sets the device identifier of the information output device 10 to “Others”. May be considered. In this case, the relay device 30 associates “others” as the MAC address, IP address, and device identifier of the information output device 10 and stores them in the device information storage unit 35.

  The case where the user who operates the information output apparatus 10 does not select the device identifier means, for example, that the information output apparatus 10 does not have a display unit for displaying a dialog box and the user inputs the device identifier. There is a case that does not have.

  Subsequently, a flow of a connection process to the application server according to the second embodiment of the present invention will be described with reference to FIG. In this figure, the control device 20 is an information terminal for operating the information output device 10. For example, a smart phone terminal or the like may be used as the control device 20. First, the control device 20 transmits a connection request message to the relay device 30 in order to connect to the relay device 30 (S21). For example, when the address information of the relay device 30 is input from the user, the control device 20 transmits a connection request message to the relay device 30 according to the input address information. In the connection procedure to the relay device 30 using the control device 20, an IP address may be used as address information, and the control device 20 may connect to the relay device 30 according to other connection procedures. A user who operates the control device 20 may generally execute the connection procedure described in the instruction manual describing the operation method of the control device 20 and the connection procedure is limited to a specific procedure. Not.

  Next, when receiving the connection request message, the relay device 30 detects the MAC address of the control device 20. The relay device 30 refers to device information associated with the detected MAC address (S22). When the relay device 30 determines that the device information is, for example, a portable terminal, the relay device 30 controls dialog box information used to select whether the connection destination is the information output device 10 or the relay device 30. It transmits to the apparatus 20 (S23).

  Next, when receiving the dialog box information transmitted in step S23, the control device 20 displays the dialog box on the input / output unit 23 (S24). Specifically, the dialog box described with reference to FIG. Next, when the information output device 10 is input as a connection destination via the dialog box, the control device 20 transmits a GUI request message to the relay device 30 (S25). The GUI request message is a message used when requesting acquisition of information related to an application server that holds a control application necessary for operating the information output apparatus 10.

  When the relay apparatus 30 receives the GUI request message transmitted from the control apparatus 20, the relay apparatus 30 transmits the received GUI request message to the information output apparatus 10 (S26). When receiving the GUI request message, the information output device 10 transmits the GUI information in which the address information of the application server holding the control application necessary for operating the information output device 10 is set to the relay device 30 (S27). . Next, the relay device 30 transmits the GUI information transmitted from the information output device 10 to the control device 20 (S28).

  Next, the control device 20 displays the received GUI information on the input / output unit 23 (S29). For example, URL information of the application server is displayed in the GUI information displayed on the input / output unit 23. The GUI information displayed on the input / output unit 23 may be shown as shown in FIG. 10, for example. When the URL information displayed on the input / output unit 23 is selected by the user, the control device 20 transmits the URL information to the relay device 30 (S30).

  Next, when receiving the URL information, the relay device 30 connects to the application server connected via the network according to the URL information (S31). When the relay device 30 acquires the control application from the application server, the relay device 30 transmits the acquired application to the control device 20 (S32). Next, the control device 20 installs the received application in the device (S33).

  By executing the operation shown in FIG. 9, the control device 20 can install a control application for operating the information output device 10. The control device 20 can use the control application as a user interface for operating the information output device 10.

  In step S22, the relay device 30 determines that the device that has transmitted the connection request message is a game machine or the like that is not a portable terminal, or the portable terminal sends a connection request message when the information output device 10 is not connected. In step S23, dialog box information different from the dialog box information for displaying FIG. 6 may be transmitted. In step S25, when a GUI request message indicating that the connection destination is the relay device 30 is transmitted from the control device 20, the relay device 30 does not execute the process of step S26. In this case, the relay device 30 may transmit the dialog box information to be transmitted when the connection destination is the relay device 30 in step S28.

  The dialog box displayed in step S <b> 24 may have more items depending on, for example, the devices connected to the relay device 30. For example, the relay device 30 may manage the table shown in FIG. 11 and display a dialog box or increase the options depending on the device that has accessed the relay device 30. The circles in FIG. 11 indicate that they are displayed as choices in the dialog box, and the crosses indicate that they are not displayed as choices in the dialog box. The table in FIG. 11 is an example, and the present invention is not limited to this.

  When the information output device 10 receives the GUI request message in step S26, the information output device 10 converts the URL of the application server holding the control application into the code output information such as a barcode or QR code (registered trademark). May be displayed. A user who operates the control device 20 may connect to the application server by reading a code displayed on the information output device 10 using the camera function of the control device 20.

  As described above, by using the communication system according to the second embodiment of the present invention, the user who operates the control device 20 does not need to search for an application server that holds the control application of the control device 20. That is, when determining that the mobile terminal is connected as the control device 20, the relay device 30 transmits the URL information of the application server acquired from the information output device 10 to the control device 20. Thereby, the user who operates the control device 20 can acquire the URL information without searching the URL information of the application server. Therefore, the user who operates the control device 20 can easily connect to the application server and acquire the control application of the information output device 10.

  In addition, when the relay device 30 has issued an IP address, when the information output device 10 disconnects from the relay device 30, or when the relay device 30 is restarted, the information output device 10 There is a possibility that an IP address different from the assigned IP address is assigned. Even in such a case, when the communication system according to the second embodiment is used, since the IP address of the relay device 30 is fixed, the control device 20 does not change the procedure for connecting to the relay device 30. Therefore, even when the user who operates the control device 20 reinstalls the control application of the information output device 10 in a situation where the IP address of the information output device 10 is changed, the control device 20 does not change the relay device 30. By connecting with, the URL of the application server that holds the control application can be acquired.

  Further, when the information output device 10 periodically communicates with the application server and the URL or the like of the application server is changed, the information output device 10 can update the URL information or the like. Therefore, even when the URL or the like of the application server is changed, the control device 20 can acquire the changed URL or the like.
