[Maintenance terminal processing]
A process flow of the maintenance terminal 12 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a flowchart showing an example of a process flow of the maintenance terminal 12 according to the embodiment.

The acquisition unit 50 recognizes the functional unit to be installed in the charging device 10 (step S10). Specifically, the acquisition unit 50 recognizes the functional unit by acquiring a beacon signal from the functional unit to be installed in the charging device 10 via the first communication unit 38a. Then, the process proceeds to step S12.

The invitation unit 52 transmits invitation information to the recognized functional unit (step S12). When the invitation unit 52 transmits the invitation information to the recognized functional unit via the first communication unit 38a, the process of adding the functional unit to the charging device 10 is started. Then, the process proceeds to step S14.

The acquisition unit 50 acquires the functional unit information from the functional unit that acquired the invitation information (step S14). Specifically, the acquisition unit 50 acquires the functional unit information from the functional unit that acquired the invitation information via the first communication unit 38a. The functional unit information includes at least information regarding the authentication mode of the functional unit. Then, the process proceeds to step S16.

The determination unit 54 determines the authentication form of the functional unit based on the functional unit information (step S16). Examples of authentication forms include, but are not limited to, a form in which a predetermined code is displayed, a form in which a predetermined code is set, and a form in which light is emitted a predetermined number of times. For example, if the functional unit has a display unit that displays various information, the determination unit 54 determines that the authentication form is a form in which a predetermined code is displayed. For example, if the functional unit has NFC (Near Field Communication) for short-range wireless communication, the determination unit 54 determines that the authentication form is a form in which a predetermined code is set. For example, if the functional unit has an LED (Light Emitting Diode) that emits light, the determination unit 54 determines that the authentication form is a form in which light is emitted a predetermined number of times. Then, the process proceeds to step S18.

The output control unit 56 controls the output unit 34 to notify the user of the authentication mode of the functional unit (step S18). The output control unit 56 causes the output unit 34 to display a message indicating that the authentication mode of the functional unit is, for example, a mode in which a specific code is displayed, a mode in which a specific code is set, a mode in which light is emitted a specific number of times, or the like. The output control unit 56 causes the output unit 34 to display a message indicating an operation that the user needs to perform to authenticate the functional unit, for example. Then, the process proceeds to step S20.

The request unit 58 requests an authentication code according to the authentication mode of the functional unit (step S20). For example, if the authentication mode of the functional unit is a mode in which a predetermined code is displayed, the request unit 58 requests that a predetermined four-digit code be displayed. For example, if the authentication mode of the functional unit is a mode in which a predetermined code is set, the request unit 58 requests that a predetermined four-digit code be set. For example, if the authentication mode of the authentication unit is a mode in which light is emitted, the request unit 58 requests that light be emitted a predetermined number of times. Then, the process proceeds to step S22.

The acquisition unit 50 acquires the authentication code (step S22). For example, if the functional unit displays a predetermined code, the acquisition unit 50 acquires video data of the functional unit displaying the predetermined code from the camera 30. For example, if the functional unit sets a predetermined code, the acquisition unit 50 acquires the code set in the functional unit via the first communication unit 38a. For example, if the functional unit emits light a predetermined number of times, the acquisition unit 50 acquires video data of the functional unit emitting light a predetermined number of times from the camera 30. Then, the process proceeds to step S24.

The authentication unit 60 determines whether the authentication code is appropriate (step S24). Specifically, the authentication unit 60 determines that the authentication code is appropriate when the authentication code requested in step S20 matches the authentication code acquired in step S22. If it is determined that the authentication code is appropriate (step S24; Yes), the process proceeds to step S26. If it is not determined that the authentication code is appropriate (step S24; No), the process proceeds to step S32.

If step S24 returns Yes, the authentication unit 60 transmits authentication information (step S26). Specifically, the authentication unit 60 transmits authentication information indicating that the device has been authenticated to be installed in the charging device 10 to the functional unit via the first communication unit 38a. Then, the process proceeds to step S28.

The acquisition unit 50 acquires an authentication completion notification (step S28). The acquisition unit 50 acquires, for example, an authentication completion notification indicating a response to the authentication information from the functional unit via the first communication unit 38a. Then, the process proceeds to step S30.

The control unit 40 sets the initial information (step S30). When the control unit 40 receives an authentication completion notification from the functional unit, it sets the initial information between the functional unit. As a result, the functional unit becomes a node of the mesh network. Then, the process of FIG. 3 ends.

If step S24 returns No, the authentication unit 60 determines that the functional unit is inappropriate (step S32). Specifically, the authentication unit 60 determines that the functional unit to be installed in the charging device 10 is inappropriate, and does not permit the functional unit to be installed in the charging device 10. Then, the process of FIG. 3 ends.

In this embodiment, the maintenance terminal 12 may have a function for identifying location information and a function for identifying a user performing authentication processing. This allows the maintenance terminal 12 to determine that the authentication processing is being performed at a specific, predetermined location, and that the authentication processing is being performed by a predetermined user. As a result, security can be strengthened.

[Authentication process]
A process flow for authenticating each functional unit of the charging device 10 will be described with reference to Fig. 4, Fig. 5, and Fig. 6.

In step S46, the maintenance terminal 12 determines that the authentication mode of the charging authentication unit 20 is NFC.

The maintenance terminal 12 displays a message on the output unit 34 (step S48). Specifically, the maintenance terminal 12 displays a message on the output unit 34 instructing the user to touch a specific position of the maintenance terminal 12 to the charging authentication unit 20. The maintenance terminal 12 displays a message such as, for example, "Please touch the back of the maintenance terminal 12 to the charging authentication unit 20." The user can touch the back of the maintenance terminal 12 to the charging authentication unit 20 by following the message displayed on the maintenance terminal 12.

The maintenance terminal 12 sends a code setting request to the charging authentication unit 20 (step S50). Specifically, the maintenance terminal 12 sends a four-digit code setting request to the charging authentication unit 20.

The charging authentication unit 20 sets the code based on the code setting request from the maintenance terminal 12 (step S52).

The maintenance terminal 12 reads the code set in the charging authentication unit 20 via short-range wireless communication (step S54).

The maintenance terminal 12 transmits the authentication information to the charging authentication unit 20 (step S56). Specifically, if the code that the maintenance terminal 12 requests the charging authentication unit 20 to set matches the code that it reads, the maintenance terminal 12 transmits the authentication information to the charging authentication unit 20.

When the charging authentication unit 20 receives the authentication information, it sends an authentication completion notification to the maintenance terminal 12 (step S58).

When the charging authentication unit 20 sends an authentication completion notification to the maintenance terminal 12, initial information is set between the maintenance terminal 12 and the charging authentication unit 20 (step S60). As a result, the charging authentication unit 20 becomes a node of the mesh network. Then, the processing in FIG. 4 ends.

(Authentication process for live section)
Next, a description will be given of a process flow in which the maintenance terminal 12 authenticates the charging unit 22. As shown in Fig. 5, when the charging unit 22 is mounted on the charging device 10, the charging unit 22 transmits a beacon signal to the maintenance terminal 12 (step S70). The maintenance terminal 12 recognizes the charging unit 22 by receiving the beacon signal from the charging unit 22.

When the maintenance terminal 12 recognizes the charging unit 22, it sends invitation information to the charging unit 22 (step S72).

When the charging unit 22 receives the invitation information, it transmits charging unit information about the charging unit 22 to the maintenance terminal 12 (step S74). The charging unit information includes at least information about the authentication mode of the charging unit 22. The charging unit information is a type of first authentication mode information or second authentication mode information.

The maintenance terminal 12 determines the authentication mode of the charging unit 22 based on the charging unit information received from the charging unit 22 (step S76). In step S76, the maintenance terminal 12 determines that the authentication mode of the charging unit 22 is LED.

The maintenance terminal 12 activates the camera 30 (step S78). The maintenance terminal 12 displays a message on the output unit 34 (step S80). Specifically, the maintenance terminal 12 displays a message on the output unit 34 instructing the user to point the camera 30 at the charging unit 22. The maintenance terminal 12 displays a message such as, for example, "Point the camera 30 at the charging unit 22." The user can point the camera 30 at the charging unit 22 by following the message displayed on the maintenance terminal 12.

The maintenance terminal 12 transmits a code display request to the charging unit 22 (step S82). Specifically, the maintenance terminal 12 transmits a code display request indicating the number of times the LED has illuminated to the charging unit 22.

The charging unit 22 causes the LED to emit light a predetermined number of times based on a code display request from the maintenance terminal 12 (step S84).

The maintenance terminal 12 captures an image of the LED using the camera 30 and determines the number of times the LED has illuminated (step S86).

The maintenance terminal 12 transmits the authentication information to the charging unit 22 (step S88). Specifically, the maintenance terminal 12 transmits the authentication information to the charging unit 22 when the number of times the LED is illuminated that is requested of the charging unit 22 matches the number of times that the maintenance terminal 12 has determined.

When the charging unit 22 receives the authentication information, it sends an authentication completion notification to the maintenance terminal 12 (step S90).

When the charging unit 22 sends an authentication completion notification to the maintenance terminal 12, initial information is set between the maintenance terminal 12 and the charging unit 22 (step S92). As a result, the charging unit 22 becomes a node of the mesh network. Then, the processing of FIG. 5 ends.

(Display authentication process)
Next, a description will be given of a process flow in which the maintenance terminal 12 authenticates the display unit 24. As shown in Fig. 6, the display unit 24 transmits a beacon signal to the maintenance terminal 12 when mounted on the charging device 10 (step S100). The maintenance terminal 12 recognizes the display unit 24 by receiving the beacon signal.

When the maintenance terminal 12 recognizes the display unit 24, it sends invitation information to the display unit 24 (step S102).

When the display unit 24 receives the invitation information, it transmits display unit information about the display unit 24 to the maintenance terminal 12 (step S104). The display unit information includes at least information about the authentication mode of the display unit 24. The display unit information is a type of first authentication mode information or second authentication mode information.

The maintenance terminal 12 determines the authentication type of the display unit 24 based on the display unit information received from the display unit 24 (step S106). In step S106, the maintenance terminal 12 determines that the authentication type of the display unit 24 is LCD.

Specifically, the maintenance terminal 12 displays a message on the output unit 34 instructing the display unit 24 to point the camera 30. The maintenance terminal 12 displays a message such as, for example, "Point the camera 30 toward the display unit 24." The user can point the camera 30 toward the display unit 24 by following the message displayed on the maintenance terminal 12.

The maintenance terminal 12 sends a code display request to the display unit 24 (step S112). Specifically, the maintenance terminal 12 sends a code display request indicating a four-digit code to the display unit 24.

The display unit 24 displays the four-digit code based on the code display request from the maintenance terminal 12 (step S114).

The maintenance terminal 12 captures an image of the display unit 24 using the camera 30 and determines the four-digit code displayed on the display unit 24 (step S116).
