The power feeding system 1 then provides power feeding service to the user via the power feeding terminal device 60 .

The management device 10 and the terminal device 30 are connected to each other via a network 90. On the other hand, the power supply terminal device 60 is not connected to the network 90 . Although the details will be described later, the power supply terminal device 60 can exchange information with the management device 10 via the terminal device 30 .

The management device 10 is configured by a computer device. This management device 10 functions as a server in the power supply system 1 . The management device 10 of the present embodiment enables a user who owns the terminal device 30 to use the power supply terminal device 60 to supply power to a device that consumes power.

Each of the terminal devices 30 is configured by a computer device such as a smart phone, a tablet computer, or a notebook computer. This terminal device 30 functions as a client in the power feeding system 1 .
In this embodiment, an example in which one user uses the power supply service realized by the power supply system 1 will be described. Therefore, in FIG. 1, one terminal device 30 possessed by one user is displayed. However, in the actual power supply system 1 , a plurality of terminal devices owned by a plurality of different users can be connected to the network 90 .

The power supply terminal device 60 (an example of a power supply device) is connected to the user's car via the power cable CA and supplies power to the connected car. The power supply terminal device 60 functions as an external power supply for the camper CR when the automobile is, for example, the camper CR. In addition, when the vehicle is an electric vehicle, the power supply terminal device 60 functions as a charging station that supplies electric power to a rechargeable battery (not shown) provided in the electric vehicle.

Here, the power supply terminal device 60 is provided, for example, in a parking lot. To explain further, the power feeding terminal device 60 is provided at a position where it can be connected to the camper CR parked in the parking lot via the power cable CA.
Although FIG. 1 illustrates that two power supply terminal devices 60 are installed, three or more power supply terminal devices 60 may be installed.

Network 90 is a communication network used for data exchange between devices. The illustrated network 90 is configured by the Internet, but is not particularly limited. The network 90 may be, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). Also, the communication line of the network 90 may be wired or wireless, and both of them may be used.

The user management unit 110 includes an application distribution unit 111 that distributes applications, a user registration unit 113 that registers users, a usage application reception unit 115 that receives applications for use of the power supply terminal device 60, and a power supply terminal device 60. and a right management unit 117 that manages the right to use.

The application distribution unit 111 transmits (distributes) software for using the power supply system 1 , that is, an application to the terminal device 30 via the network 90 . In other words, the application distribution unit 111 enables the user to download the application to the terminal device 30 .

The user registration unit 113 executes user registration performed by the user operating the terminal device 30 . In the example of FIG. 2, the user registration unit 113 receives specification of a user name and password and outputs a user ID, which is user identification information, in user registration processing.

The usage application accepting unit 115 (an example of the accepting unit) accepts a user's login performed by the user operating the terminal device 30 . Further, the usage application accepting unit 115 accepts an application for usage of the power feeding terminal device 60 . In this usage application, identification information of the user (that is, user ID), identification information of the power supply terminal device 60 that performs power supply (power supply device ID to be described later), usage time of the power supply service (that is, power supply time), etc. are specified. Accepts application information from users. The usage time includes information on the date when the power supply service is used, the time when the power supply service is started to be used, and the time from the start to the end of the power supply service (that is, period).
In addition, the usage application accepting unit 115 pays the fee for receiving the power supply service, that is, performs settlement. The fee here is set so as to vary according to, for example, the power feeding time. Also, settlement is performed by well-known techniques such as payment by credit card.

The right management unit 117 manages the right to use the power supply service, that is, the right to supply power using the power supply terminal device 60 . Specifically, when the payment by the usage application accepting unit 115 is completed, the right management unit 117 generates the right to receive the power supply service for which the payment has been made, that is, the usage right. Moreover, the right management unit 117 cancels the usage right when the power supply by the power supply terminal device 60 is completed.
Then, the right management unit 117 creates usage information for enabling the user to use the power supply service when the usage right is generated. The usage information is created based on the application information described above. The usage information includes identification information of the user who uses the power supply service, identification information of the power supply terminal device 60 that supplies power, and information on the usage time of the power supply service.

The power management unit 130 has a power information management unit 131 that manages power information, and a management information output unit 135 that outputs the power information managed by the power information management unit 131 .

The management information output unit 135 outputs the power information managed by the power information management unit 131 to the administrator of the power supply system 1, the owner of the power supply terminal device 60, and the like. For example, the management information output unit 135 transmits the usage history of the power supply terminal device 60 stored by the power supply information management unit 131 to the owner of the power supply terminal device 60 . This enables the owner of the power supply terminal device 60 to grasp the usage status of the power supply terminal device 60 owned by himself/herself.

In addition, the management information output unit 135 notifies the administrator of the power supply system 1 and the owner of the power supply terminal apparatus 60 when trouble occurs in the power supply terminal apparatus 60 . This enables the owner of the power supply terminal device 60 to quickly solve the trouble of the power supply terminal device 60 . Here, for example, the management information output unit 135 sends the usage history of the power supply terminal device 60 to the computer device (smartphone, etc., not shown) of the owner of the power supply terminal device 60 as character information such as e-mail or image information. Output. On the other hand, the management information output unit 135 outputs the trouble of the power supply terminal device 60 as voice information to the owner's smart phone or the like. By outputting the information as voice information by telephone, it is possible to reduce the chances that the administrator forgets to check the information as in the case of character information. As a result, the owner of the power supply terminal device 60 can more reliably recognize the trouble and solve the trouble of the power supply terminal device 60 more quickly.

The power supply management unit 150 has an authentication unit 151 that authenticates users, and an energization processing unit 153 that performs processing for starting power supply services for authenticated users.

The authentication unit 151 performs authentication upon receiving an instruction from the terminal device 30 . Although the details will be described later, in this authentication, the power feeding device ID of the power feeding terminal device 60 and the like are used.
The power supply processing unit 153 (an example of an output unit) outputs to the terminal device 30 an instruction for the power supply terminal device 60 to supply power to the device. Specifically, the energization processing unit 153 outputs the above-described usage information and status information for turning on the power supply terminal device 60 . In addition, the energization processing unit 153 receives, from the terminal device 30, an energization end notification, which is a notification that energization has ended.

(Power supply terminal device 60)
FIG. 6 is a schematic perspective view of the power supply terminal device 60 of this embodiment.
FIG. 7 is a diagram showing a configuration example of the power supply terminal device 60 of this embodiment.

As shown in FIG. 6 , the power supply terminal device 60 has a columnar pole 600 and a housing 601 provided on the pole 600 . The power supply terminal device 60 is provided, for example, on the side of a parking space in a parking lot. The power supply terminal device 60 is connected to, for example, a camper CR (see FIG. 1) parked in a parking space via a power cable CA (see FIG. 1), thereby enabling power supply to the camper CR.

As shown in FIG. 7, the housing 601 includes an A/D converter 610 that converts an analog voltage of 100 V AC applied from the outside into a digital signal, and a control unit 630 that controls each component of the power supply terminal device 60. , and a power supply relay 650 (an example of a power supply unit) that receives a control signal from the control unit 630 and switches on/off. The housing 601 also has an LED 67 that emits light and a BLE I/F 679 that communicates.

Here, the power relay 650 shown in FIG. 7 has a timer 651. This timer 651 measures the energization time, that is, the power supply time. To explain further, the timer 651 starts measuring the elapsed time by receiving a signal from the control unit 630, and cuts off the power supply relay 650 when a predetermined time elapses. As a result, power supply to the camper CR ends after a predetermined time has elapsed.

The LED 67 is a light-emitting element that receives a control signal from the control unit 630 and switches between lighting and extinguishing. The LED 67 notifies the user of the operation state of the power supply terminal device 60 by the lighting mode. And LED67 is provided with 1st LED671, 2nd LED672, and 3rd LED673 (refer FIG. 6), and is comprised. For example, by lighting the first LED 671 in red, the user is notified that power is being supplied. Also, by lighting the second LED 672 in green, the user is notified that the power supply has ended. Also, by lighting the third LED 673 in yellow, the user is notified that the power supply terminal device 60 is on standby.

A BLE I/F 679 (an example of a communication unit) receives control signals from the control unit 630 and communicates with the terminal device 30 . This BLE I/F 679 has a BLE communication circuit (not shown) and performs BLE communication with the terminal device 30 using this BLE circuit.

In the present embodiment, the communication range between the terminal device 30 and the power supply terminal device 60 using BLE communication is set to 30 meters, for example. Accordingly, when BLE communication is possible between the terminal device 30 and the power feeding terminal device 60, it can be determined that the terminal device 30 exists near the power feeding terminal device 60. FIG.
Note that the communication range by BLE communication is not limited to the above example, and can be set up to, for example, 500 meters according to communication standards and the like.

The power supply terminal device 60 configured as described above does not have a configuration for connecting to a network 90 such as the Internet like the network I/F 312 of the terminal device 30, for example. That is, the power supply terminal device 60 of this embodiment is not connected to the network 90 . For example, the power supply terminal device 60 does not have an IP address set, and cannot communicate information with the management device 10 via the network 90 by designating the management device 10 as a communication destination, for example. The same applies to the management device 10 , and the management device 10 cannot communicate information with the power supply terminal device 60 via the network 90 by designating the power supply terminal device 60 as a communication destination.

On the other hand, the power feeding terminal device 60 has the BLE I/F 679 and can perform one-to-one communication with the terminal device 30 in a state where communication with the terminal device 30 is established. However, the terminal device 30 cannot perform BLE communication with a communication device such as another terminal device while communication is established with the terminal device 30 .
In this way, the power supply terminal device 60 can communicate with one communication device such as the terminal device 30 by BLE communication, but cannot communicate with two or more communication devices at the same time. It is configured.

(Operation of power feeding system 1)
Next, the operation of the power supply system 1 will be described.
The power supply system 1 performs a user registration operation in which a user acquires a user ID, a usage application operation in which a user applies in advance to use the power supply service in the power supply terminal device 60, and a power supply operation in which power is supplied to the camper CR. .
Each of the user registration operation, usage application operation, and power supply operation will be described below.

(User registration operation)
The user registration operation is started when the user operates the terminal device 30 . Specifically, when the user operates the terminal device 30 , the application distribution unit 111 of the management device 10 transmits the application to the terminal device 30 via the network 90 . That is, the application is downloaded to the terminal device 30 .

Next, when the user operates the terminal device 30 , the user name and password are transmitted from the application management section 31 of the terminal device 30 to the management device 10 . This user name and password are stored by the user registration unit 113 . Then, the user registration unit 113 transmits the user ID assigned to each user to the terminal device 30 . This user ID is stored in the user registration unit 113 of the terminal device 30 .

(Usage application operation)
When applying for use, the application management unit 31 of the terminal device 30 executes login processing from the application when the user operates the terminal device 30 . Then, the user operates the terminal device 30 to select the power supply terminal device 60 that receives the power supply service and designates the usage time (that is, the power supply time). The usage application reception unit 115 of the management device 10 receives this designation. Then, the usage application accepting unit 115 calculates the usage fee according to the received power supply terminal device 60 and the usage time, and transmits the usage fee to the terminal device 30 . When the terminal device 30 is operated, the usage application receiving unit 115 of the management device 10 executes the payment. In addition, the right management unit 117 of the management device 10 generates the usage right of the power supply terminal device 60 associated with the user.

Here, the user has completed the application for use of the power feeding service by communicating with the management device 10 via the terminal device 30 .

For example, the user arrives at the parking lot where the power supply terminal device 60 selected in the usage application is installed. Then, the user approaches the power supply terminal device 60 while carrying the terminal device 30 . When the terminal device 30 is positioned within a predetermined distance from the power feeding terminal device 60, the terminal device 30 receives the advertising signal cast by the power feeding terminal device 60 (S801). The terminal device 30 makes a connection request to the power supply terminal device 60 in response to the advertise signal (S802). Then, BLE communication is established between the power feeding terminal device 60 and the terminal device 30 .

Next, in the terminal device 30, the authentication unit 35 generates a random number value (S803). The authentication unit 35 of the terminal device 30 then transmits the generated random number to the power supply terminal device 60 (S804).

The control unit 630 of the power supply terminal device 60 generates a session key using the random value acquired from the terminal device 30 and the power supply terminal key (S805). Here, the power supply terminal key is held in advance by the power supply terminal device 60 and is a key individually created for each power supply terminal device 60 based on the master key held by the management device 10 . Also, the session key is created using a random number value generated each time the user uses the power supply service, and is used only for one use of the power supply service.

Furthermore, the control unit 630 of the power supply terminal device 60 stores the power supply device ID of the power supply terminal device 60, key version information indicating the version of the power supply terminal key, count information indicating the number of times of authentication, and the session key generated in S805. , the power supply terminal MAC value, which is the MAC value calculated by the power supply terminal device 60, is generated (S806). A MAC (Message Authentication Code) value is a value for protecting and authenticating the integrity of information by allowing the configuration holding the common key to detect changes in the content of the information. As described above, the power supply terminal key is created for each power supply terminal device 60 based on the master key and the power supply device ID. In the present embodiment, the master key held by the management device 10 and the power supply terminal key form a common key relationship.

Then, the power supply terminal device 60 transmits the created authentication information to the terminal device 30 via the BLE I/F 679 (S807). The authentication information transmitted by the power supply terminal device 60 includes the power supply device ID, key version information, count information, and power supply terminal MAC value.

Subsequently, the authentication unit 35 of the terminal device 30 transmits the authentication information to the management device 10 via the network 90 (S808). The authentication information transmitted by the terminal device 30 includes a power feeding device ID, key version information, count information, a power feeding terminal MAC value, a generated random number value, and a user ID.

The authentication unit 151 of the management device 10 generates a power supply terminal key based on the master key it holds and the power supply device ID of the power supply terminal apparatus 60 acquired via the terminal apparatus 30 . Further, the authentication unit 151 of the management device 10 generates a session key based on the generated power supply terminal key and the random value obtained from the terminal device 30 (S809).
Also, the authentication unit 151 of the management device 10 generates a MAC value for verification from the generated session key, the power supply device ID acquired from the terminal device 30, the key version information, and the count information.
Then, the authentication unit 151 of the management device 10 authenticates that the information from the power supply terminal device 60 communicating with the terminal device 30 is genuine (S810). Authentication by the authentication unit 151 of the management device 10 is performed by verifying whether or not the generated MAC value for verification matches the power supply terminal MAC value acquired via the terminal device 30 .

After that, when the authenticating unit 151 determines that the authentication result is correct, the energization processing unit 153 of the management device 10 creates status information instructing to turn on the power supply terminal device 60 . Then, the authentication unit 151 of the management device 10 generates a management MAC value, which is a MAC value calculated by the management device 10, from the session key generated in S809, the count information, and the status information (S811). The management device 10 then transmits the authentication information to the terminal device 30 (S812). The authentication information transmitted by the management device 10 includes count information, status information, and the generated management MAC value.

Further, when the authenticating unit 151 determines that the authentication result is correct, the energization processing unit 153 of the management device 10 refers to the usage information corresponding to the acquired user ID (S813). Then, the energization processing unit 153 of the management device 10 transmits the usage information and the time information representing the current time to the terminal device 30 (S814). Note that the management device 10 transmits the usage information and the time information to the terminal device 30 in association with the authentication information.

The terminal device 30 receives an operation from the user for the power feeding terminal device 60 to start power feeding (S815). Specifically, the image display unit 37 of the terminal device 30 receives an acceptance image 400 ( FIG. 10 reference). This reception image 400 can be regarded as an image displayed on the operation panel 305 on condition that the terminal device 30 is positioned within a predetermined distance range from the power supply terminal device 60 . Further, the predetermined distance can be exemplified by, for example, a distance at which communication by BLE communication is possible.

As shown in FIG. 10, a reception image 400 displayed on the operation panel 305 of the terminal device 30 includes location information of the power feeding terminal device 60, power feeding pole information 405 capable of specifying the power feeding terminal device 60, and an operation by the user. A prompting message image 406 is displayed. Further, in the acceptance image 400, an acceptance image 407 for accepting an instruction to allow the start of power supply and a restriction image 408 for accepting an instruction to restrict the start of power supply are displayed.

Then, when the user's operation on the allowable image 407, that is, the operation to allow the start of power supply is received from the user, as shown in FIG. is transmitted to the power supply terminal device 60 (S816). The start information transmitted by the terminal device 30 includes count information, status information, management MAC value, usage information, and time information.

The control unit 630 of the power supply terminal device 60 that has received the start information authenticates that the information from the management device 10 acquired via the terminal device 30 is genuine (S817). The control unit 630 of the power supply terminal device 60 generates a MAC value for verification from the session key generated in S805 and the count information and status information acquired via the terminal device 30 . Authentication by the control unit 630 of the power supply terminal device 60 is performed by verifying whether or not the generated MAC value for verification matches the management MAC value acquired via the terminal device 30 .

As described above, in the power feeding system 1 of the present embodiment, by performing verification using the common key as described above, mutual communication between the management device 10, the terminal device 30, and the power feeding terminal device 60 is performed via the terminal device 30. Authenticate. Thus, in the power feeding system 1 , security is ensured by mutual authentication via the terminal device 30 even if information is not directly transmitted and received between the management device 10 and the power feeding terminal device 60 .

After that, if the authentication result is correct, the control unit 630 of the power supply terminal device 60 corrects the time of the timer 651 based on the current time information obtained via the terminal device 30 (S818). Note that the power feeding terminal device 60 cannot communicate with the outside except for communicating with the terminal device 30 . On the other hand, the time calculated by counting the timer 651 of the power supply terminal device 60 may deviate from the correct time. Therefore, in the present embodiment, the power supply terminal device 60 corrects the time of the timer 651 when communicating with the terminal device 30 .

Then, the control unit 630 of the power supply terminal device 60 operates the power supply relay 650 to start energization (S819). Also, the timer 651 starts timing (S820).
As described above, the power supply terminal device 60 of the present embodiment starts power supply when the terminal device 30 receives the allowable image 407 (see FIG. 10), which is a predetermined operation from the user. It's becoming

Next, the power supply terminal device 60 transmits a power supply notification to the terminal device 30 by BLE communication (S821). Then, the image display unit 37 of the terminal device 30 that has received the power supply notification displays the power supply image 401 (see FIG. 11A) indicating that power is being supplied on the operation panel 305 of the terminal device 30 (S822).
Further, the terminal device 30 notifies the management device 10 of information indicating that power supply has started, along with the device ID and the user ID, via the network 90 (S823).

As described above, in the power feeding system 1 of the present embodiment, the user possesses the terminal device 30 and is positioned near the power feeding terminal device 60 to be used, and the allowable image 407 displayed on the operation panel 305 of the terminal device 30 (See FIG. 10), the power supply terminal device 60 can be brought into a state in which power can be supplied.
Then, the usage time elapses based on the application for usage by the user.

Next, the timer 651 detects the expiration of the usage time (S824). Then, the power supply relay 650 of the power supply terminal device 60 terminates energization (S825). Furthermore, the power supply terminal device 60 transmits a power supply end notification to the terminal device 30 by BLE communication (S826). Then, the image display unit 37 of the terminal device 30 that has received the power supply end notification displays the end image 403 (see FIG. 11B) indicating that the power supply has ended (S827). Further, the terminal device 30 transmits a power-on end notification to the management device 10 via the network 90 (S828). Then, in the management device 10, the usage right is deleted (S829).

As described above, in the power supply system 1 of the present embodiment, the power supply terminal device 60 that cannot communicate with the management device 10 via the network 90 is instructed to supply power based on the exchange of information via the terminal device 30 . Further, since the power supply terminal device 60 does not require a device for performing upper communication via the network 90, for example, the installation cost can be reduced.

In the example of the power supply system 1 in the above-described embodiment, the user designates in advance the power supply terminal device 60 to which power is to be supplied, for example, in a usage application received by the usage application reception unit 115, but the present invention is not limited to this aspect. For example, the management device 10 generates a right to use one of the plurality of power supply terminal devices 60 for a user who has applied for use. On the other hand, the user possesses the terminal device 30 and is located near the power supply terminal device 60 that he wishes to use. In this case, the user can check the LED 67 (see FIG. 6) of the power supply terminal device 60, for example, and use the power supply terminal device 60 whose third LED 673, which indicates that it is on standby, is lit in yellow.
In the power feeding system 1, the power feeding terminal device 60, the terminal device 30, and the management device 10 are connected by BLE communication between the power feeding terminal device 60 and the terminal device 30 and communication between the terminal device 30 and the management device 10 via the network 90. 10, mutual authentication and transmission/reception of usage information are performed. Thereby, the power feeding system 1 can make the power feeding service available to the user.

<Modification>
Here, extended use of the power supply service will be described.
FIG. 12 is an explanatory diagram of an image displayed on the terminal device 30 when the power feeding service ends.

For example, the power supply terminal device 60 specifies a predetermined time (for example, 5 minutes before the end) before the end of the power supply based on the time counted by the timer 651 . Then, the power feeding terminal device 60 transmits a preliminary end notification that notifies the terminal device 30 of the end of power feeding in advance by BLE communication. Further, the terminal device 30 transmits the received advance termination notification to the management device 10 via the network 90 . The management device 10 causes the terminal device 30 to display an image for accepting an extension of the usage time via the network 90 based on the received preliminary end notification.

As shown in FIG. 12, the image displayed on the operation panel 305 of the terminal device 30 includes a notice image 501 that foretells that the usage time will end and a message image 502 that prompts extension of the power feeding time. . Further, the images displayed on the operation panel 305 of the terminal device 30 include an extension button image 503 for receiving an instruction from the user to extend the power supply time, and a consent to end the power supply at a predetermined time without extending the power supply time. An end button image 504 received from the user is included.

It should be noted that when the user accepts the operation of the extension button image 503 on the operation panel 305 of the terminal device 30, the procedure for extending the use of the power supply service is performed in the same manner as the procedure for application for use described above.

<Modification>
Next, update processing of the power supply terminal device 60 will be described.
FIG. 13 is an operation flow for updating the program of the power supply terminal device 60 of this embodiment.

As described above, in order to perform mutual authentication between the management device 10 and the power supply terminal device 60, the power supply terminal device 60 stores a version of the power supply terminal key corresponding to the master key of the management device 10. . However, from the viewpoint of security, the version of the master key is updated in the management device 10 . Along with this, the power supply terminal device 60 needs to update the power supply terminal key. Not limited to such an example of the power supply terminal key, the power supply terminal device 60 may require updating of the program used by the control unit 630 .

As shown in FIG. 13, the management device 10 determines whether or not it is necessary to update the program of the power supply terminal device 60 (S1301). When the management device 10 determines that the program needs to be updated (YES in S1301), the management device 10 identifies the power supply terminal device 60 to be updated (S1302). Furthermore, the management device 10 refers to the application information for the identified power supply terminal device 60 (S1303).

Then, the management device 10 determines whether or not there is a user application for use of the target power supply terminal device 60 (S1304). When the user applies for use of the target power supply terminal device 60 (YES in S1304), the management device 10 obtains the user's consent to cooperate in updating the program of the power supply terminal device 60. is notified (S1305). Note that the management device 10 can present compensation such as providing a power supply service free of charge to the user who cooperates with the update.

Next, the management device 10 determines whether the user has agreed to cooperate with the update (S1306). This consent can be determined, for example, by displaying a predetermined image on the operation panel 305 of the terminal device 30 and operating the operation panel 305 by the user. Then, if the user agrees to cooperate with the update (YES in S1306), for example, when the terminal device 30 is positioned near the target power supply terminal device 60, the management device 10 updates the update program information. It transmits to the terminal device 30 (S1307). Further, for example, in a state in which BLE communication is established between the terminal device 30 and the power supply terminal device 60, the management device 10 transmits update permission information for permitting update of the program to the terminal device 30 (S1308). .

Then, the power supply terminal device 60 executes the above-described mutual authentication with the management device 10 via the terminal device 30, and acquires the update program and the update permission information from the terminal device 30 (S1309). In the power supply terminal device 60, the update program received from the terminal device 30 updates the controller 630 (S1310).
As described above, the management device 10 updates the program of the power supply terminal device 60 via the user's terminal device 30 .

If the management device 10 determines that the program update is not necessary (NO in S1301), and if there is no application for use by the user of the target power supply terminal device 60 (NO in S1304), the user updates the program. (NO in S1306), the process ends.

Here, in the above example, it is assumed that the user has made a reservation for use of the power supply terminal device 60 whose program is to be updated, but the present invention is not limited to this example. Even if the user does not apply for use of the target power supply terminal device 60 , the user who uses this service may be asked to cooperate in updating the program of the power supply terminal device 60 .

<Modification>
Next, processing when an error occurs in the power supply terminal device 60 will be described.
As described above, the power supply terminal device 60 cannot directly communicate with the management device 10 without the terminal device 30 interposed therebetween. On the other hand, an error such as a failure or failure may occur in the power supply terminal device 60 . In such a case, the management device 10 cannot directly collect error information from the power supply terminal device 60 .

Therefore, the power supply terminal device 60 notifies the management device 10 of the error information of its own device via the terminal device 30 existing near its own device. For example, the power supply terminal device 60 establishes BLE communication with the nearby terminal device 30 and obtains the user's consent to transmit the error information to the management device 10 . Also in this case, the user may be provided with a consideration such as, for example, providing the power supply service free of charge. Then, the power supply terminal device 60 transmits the error information to the terminal device 30 of the user with whom consent has been obtained. Furthermore, the terminal device 30 transmits the acquired error information to the management device 10 via the network 90 .

In this manner, in the power supply system 1 of the present embodiment, the management device 10 can collect error information that has occurred in the power supply terminal device 60 .

<Modification>
In the above description, it was explained that the terminal device 30 and the power feeding terminal device 60 perform BLE communication. . For example, other wireless communication such as ultrasonic communication or Wi-Fi communication (registered trademark, Wireless Fidelity) may be used in place of or in addition to BLE communication. For example, either the ultrasonic communication or the non-ultrasonic wireless communication may be started first, or the ultrasonic communication and the non-ultrasonic wireless communication may be started at the same time.

Also, for example, communication between the terminal device 30 and the power supply terminal device 60 may be performed only by ultrasonic communication. To explain further, the terminal device 30 and the power supply terminal device 60 may be configured to perform two-way communication using ultrasonic waves. In this configuration, the power feeding terminal device 60 is provided with a microphone (not shown). A microphone (not shown) of the power supply terminal device 60 receives the ultrasonic signal transmitted from the terminal device 30 .

<Other application examples of the service>
Furthermore, the equipment to which power is supplied by the power supply system 1 of this embodiment is not limited to the camper CR. For example, a device to which power is supplied by the power supply system 1 may be a vehicle such as an electric vehicle, an electric motorcycle, an electric cart, or an electric bicycle. Furthermore, the device to which power is supplied by the power supply system 1 may be a smart phone, a tablet terminal, a portable rechargeable battery, or the like.

In addition, although the power supply terminal device 60 or the like provided in the power supply system 1 is a device that provides a power supply service to the user upon payment by the user, regarding the use of devices that provide other services to the user, the power supply system 1 configuration may be used.

For example, instead of the power supply terminal device 60, a washing machine (not shown) of a laundromat may be provided, and BLE communication may be performed between the washing machine and the terminal device 30. In this case as well, the management device 10 receives a usage application for using the washing machine from the user via the terminal device 30, for example. Then, when the terminal device 30 owned by the user who applied for use is located near the washing machine, mutual authentication is performed among the control unit of the washing machine, the terminal device 30 and the management device 10, and the washing machine is used. becomes possible.

In the above system, the management device 10 sends authentication information for mutual authentication to the control unit of the washing machine via the terminal device 30 . In addition, the management device 10 sends usage information for enabling usage of the washing machine to the control unit of the washing machine via the terminal device 30 . This usage information includes service usage time information based on the user's usage application. Then, the washing machine controls usage by the user based on the obtained usage time information and the clocking of a built-in timer (not shown).

Examples of other power supply services include not only the above-mentioned laundromat, but also coin parking, shower rooms and toilets at campsites, and various services such as car sharing. Even in this case, even if the device providing the service cannot directly communicate with the management device 10 via the network 90, the authentication information for mutual authentication and the use of the service can be obtained via the terminal device 30. It suffices to exchange usage information to enable In this case as well, the usage information includes usage information relating to the time the user uses the service. Then, the service providing apparatus that provides the service may control the use of the service by the user based on the obtained usage time information and the clocking of a built-in timer (not shown).

Also, in the above explanation, it was explained that payment was made by credit card, but it is not limited to this. In the power feeding system 1, for example, known payment means such as a contactless IC card, QR code (registered trademark) payment, bar code payment, etc. can be employed.

Also, in the above description, it was explained that the operation state of the power supply terminal device 60 is indicated by the lighting mode of the LED 67 (see FIG. 6), but the present invention is not limited to this. For example, the operating state of the power supply terminal device 60 may be indicated by displaying an image or the like on the terminal device 30 . Here, the operation state of the power supply terminal device 60 includes in use (remaining use time), unpaid (unpaid time), reserved (reserved use start time), unavailable (failure type, expected recovery time), and the like. .

Also, the power supply system 1 may be provided with a printing device capable of printing information on power supply, such as the power supply end time, on a piece of paper (a so-called sticker). By sticking this sticker on the window of the electric vehicle, for example, the administrator of the power supply terminal device 60 other than the user can grasp the power supply end time and the like.

<Second embodiment>
FIG. 14 is a schematic diagram of the service providing system 2 of the second embodiment.
In the description of the second embodiment, the same reference numerals are given to the same configurations as those of the above-described embodiment and modifications, and detailed description thereof will be omitted.

As shown in FIG. 14, the service providing system 2 of the second embodiment provides a parking service using a parking facility 700 for parking the vehicle 100 of the user. The parking facility 700 is provided with a parking space 710 where the vehicle 100 is parked, a bench 720 on which the user sits, and a parking block 730 for the vehicle 100 .

The service providing system 2 includes a management device 10 (see FIG. 1), a terminal device 30 (see FIG. 1), a power feeding terminal device 60, a parking facility 700, a parking terminal device 71 for managing parking, It has a sensor device 73 that detects the vehicle 100 and a warning light 75 that emits light. The power supply system 1 uses the power supply terminal device 60 to provide the user with power supply service, and uses the parking terminal device 71 to provide the user with the parking service.

The management device 10 of the second embodiment enables the user who owns the terminal device 30 to park the vehicle 100 in the parking space 710 via the parking terminal device 71 . The management device 10 of the second embodiment has the same functions as when realizing the power supply service, and realizes the parking service as well as the power supply service.

The management device 10 of the second embodiment accepts applications for using the parking facility 700 and manages the right to use the parking facility 700 . The management device 10 also manages parking information for managing the parking facility 700 and outputs usage information regarding the use of the parking facility 700 . The usage information includes time information regarding the time when the parking facility 700 can be used by the user. Then, the parking terminal device 71 of the second embodiment performs mutual authentication with the management device 10 via the terminal device 30 . Furthermore, when the mutual authentication is correct, the parking terminal device 71 provides a parking service using the parking facility 700 within the usage time based on the usage information.

The terminal device 30 of the second embodiment enables the user to use the parking service as well as the power supply service.

Parking terminal device 71, like power supply terminal device 60, is not connected to network 90 (see FIG. 1). On the other hand, the parking terminal device 71 can perform one-to-one communication with the terminal device 30 in a state where communication with the terminal device 30 is established. The parking terminal device 71 of the second embodiment can exchange information with the management device 10 via the terminal device 30 .
Then, the parking terminal device 71 performs mutual authentication with the management device 10 via the terminal device 30 . Furthermore, the parking terminal device 71 makes the parking space 710 available to the user or makes the parking space 710 unavailable to the user based on the usage information created in response to the reservation of the parking facility 700 made by the user. state. A parking terminal device 71 according to the second embodiment uses a warning light 75 to control whether or not the parking facility 700 can be used.

The parking terminal device 71 is electrically connected to the sensor device 73 and the warning light 75 respectively. The parking terminal device 71 controls the sensor device 73 and acquires a detection signal from the sensor device 73 . The parking terminal device 71 also controls the operation of the warning light 75 .

The sensor device 73 has a light-emitting portion 731 that emits infrared rays and a light-receiving portion 733 that receives the infrared rays emitted by the light-emitting portion 731 . The sensor device 73 sends to the parking terminal device 71 light emission information regarding light emission by the light emitting unit 731 and light reception information regarding light reception by the light receiving unit 733 . Then, sensor device 73 identifies whether or not vehicle 100 is parked in parking space 710 . For example, when the vehicle 100 is parked in the parking space 710 , the infrared rays emitted from the light emitting portion 731 are blocked by the vehicle 100 and are not received by the light receiving portion 733 . On the other hand, when vehicle 100 is not parked in parking space 710 , infrared rays emitted from light emitting portion 731 are received by light receiving portion 733 .

Also, the light-emitting portion 731 is provided at a corner of the parking space 710 . On the other hand, light receiver 733 is provided at another corner of parking space 710 . In the second embodiment, the light emitter 731 and the light receiver 733 are arranged diagonally in the parking space 710 . The direction of the infrared rays emitted from the light emitting unit 731 to the light receiving unit 733 is along the diagonal line of the parking space 710 (chain line in FIG. 14). In the sensor device 83 , the light-emitting portion 731 and the light-receiving portion 733 are arranged diagonally to set the detection range in most of the vertical and horizontal directions of the parking space 710 . This makes it easy for sensor device 83 to detect the presence or absence of vehicle 100 regardless of the size of vehicle 100 parked in parking space 710 .

The warning light 75 is provided on the parking space 710 side, for example. Also, the warning light 75 is provided near the power supply terminal device 60 and the parking facility 700 . Furthermore, the warning light 75 is installed above the parking space 710 . The warning light 75 emits, for example, rotating light. Specifically, the warning light 75 emits light by reflecting the light from the light source by a reflecting mirror that rotates around the light source. Also, the warning light 75 may be one that emits red light, for example.

The warning light 75 notifies the user that the parking space 710 cannot be used by emitting light. The warning light 75 of the second embodiment emits, for example, red light while rotating, and thus psychologically acts to make it difficult to park the vehicle 100 in the parking space 710 . On the other hand, the warning light 75 informs the user that the parking space 710 is available by turning off. That is, the warning light 75 makes the user think that the vehicle 100 can be parked in the parking space 710 by turning off the light.

It should be noted that in the second embodiment, the parking terminal device 71 is an example of a service providing device. The warning light 75 is an example of the notification means. The sensor device 73 is an example of detection means.

Next, the operation of the service providing system 2 of the second embodiment will be explained.
FIG. 15 is an explanatory diagram of the operation of the service providing system 2 of the second embodiment.

In the service providing system 2 , the sensor device 73 detects the vehicle 100 in the parking space 710 . As shown in FIG. 15, the parking terminal device 71 determines whether or not the sensor device 73 has detected for a specific time (for example, 10 seconds) or longer (S1501). Here, in the sensor device 73, when the infrared rays emitted by the light-emitting portion 731 are not received by the light-receiving portion 733, the object is detected.

Then, when the sensor device 73 has detected for a specific time or longer (YES in S1501), the parking terminal device 71 starts emitting light from the warning light 75 (S1502). In the second embodiment, the warning light 75 emits red light.

After that, the parking terminal device 71 determines whether the mutual authentication with the management device 10 via the terminal device 30 is correct (S1503). Then, when the parking terminal device 71 determines that the mutual authentication with the management device 10 is correct (YES in S1503), the parking terminal device 71 stops the light emitting operation of the warning light 75 (S1504). ).

Thereafter, the user uses the service of parking the vehicle 100 in the parking space 710 during the usage time of the parking space 710 set as the usage information. This usage time is set when the user makes a reservation, for example, from several hours to 24 hours.
Then, the parking terminal device 71 determines whether or not the usage time of the parking service has expired based on the usage information of the parking service (S1505). When the parking terminal device 71 determines that the parking service has ended (YES in S1505), the series of processing ends.

If the vehicle 100 is parked in the parking space 710 even after the usage time has ended, the parking terminal device 71 activates the warning light 75 through S1501 and S1502. As a result, if there is a vehicle 100 that continues to park even after the usage time has passed, the warning light 75 will emit light again.

Here, if the detection by the sensor device 73 is not longer than the predetermined time in S1501 (NO in S1501), the parking terminal device 71 does not activate the warning light 75. For example, parking space 710 may only be crossed temporarily, such as by a person or animal passing through parking space 710 . Activating the warning light 75 even in such a case makes people passing by temporarily wary more than necessary. Therefore, in the service providing system 2 of the second embodiment, the warning light 75 is operated under the condition that the detection by the sensor device 73 is performed for a predetermined time or longer.

If the mutual authentication is not correct in S1503 (NO in S1503), the process returns to S1502 and the operation of the warning light 75 is continued.

Thus, in the service providing system 2 of the second embodiment, it is not essential to install a special structure in the parking space 710, for example, when managing parking.

Also, the service providing system 2 of the second embodiment may include a speaker device. Then, in the service providing system 2, a warning sound such as a buzzer may be output from a speaker device in accordance with the light emission of the warning light 75. FIG. Specifically, when the sensor device 73 detects that the vehicle 100 is parked in the parking space 710, the warning light 75 emits light and a sound is output from the speaker device. After that, mutual authentication is performed between the management device 10 and the parking terminal device 71 via the terminal device 30, and the sound output from the speaker device is stopped as the warning light 75 is turned off. In this manner, whether or not the parking space 710 can be used may be determined by warning by the light of the warning light 75 and by sound from the speaker device.
Note that the service providing system 2 may notify the availability of the parking space 710 only by a speaker device instead of the warning light 75 .

In the service providing system 2 of the second embodiment, for example, when mutual authentication between the management device 10 and the parking terminal device 71 is performed using the terminal device 30 on the screen of the terminal device 30 of the user, the light is turned on. It may be displayed that the warning light 75 that has been turned off will be extinguished.
