Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. <First Embodiment> FIG. 1 is a schematic diagram of a power supply system 1 according to the first embodiment.

[0009] (Power Supply System 1) As shown in FIG. 1, the power supply system 1 includes a management device 10 that manages information in the system, a terminal device 30 possessed by a user, and a power supply terminal device 60 that supplies power to equipment. And the power supply system 1 provides a power supply service to the user via the power supply terminal device 60.

[0010] The management device 10 and the terminal device 30 are connected to each other via the network 90. In contrast, the power supply terminal device 60 is not connected to the network 90. Although details will be described later, the power supply terminal device 60 can communicate information with the management device 10 via the terminal device 30.

[0011] The management device 10 is constituted 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 possesses the terminal device 30 to supply power to a device that consumes power by using the power supply terminal device 60.

[0012] Each of the terminal devices 30 is constituted by a computer device such as a smartphone, a tablet computer, or a notebook computer. This terminal device 30 functions as a client in the power supply system 1. In the present 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 shown. However, in the actual power supply system 1, a plurality of terminal devices respectively possessed by different users can be connected to the network 90.

[0013] The power supply terminal device 60 (an example of a power supply device) is connected to the user's automobile via the power cable CA and supplies power to the connected automobile. When the automobile is, for example, a camping car CR, the power supply terminal device 60 functions as an external power supply for the camping car CR. Further, when the automobile is, for example, an electric vehicle, the power supply terminal device 60 functions as a charging stand that supplies power to a rechargeable battery (not shown) provided in the electric vehicle.

[0014] Here, the power supply terminal device 60 is provided, for example, in a parking lot. To explain further, the power supply terminal device 60 is provided at a position where it can be connected to a camping car CR parked in the parking lot via a power cable CA. In addition, in FIG. 1, although it is illustrated that two power supply terminal devices 60 are installed, three or more power supply terminal devices 60 may be provided.

[0015] The network 90 is a communication network used for data exchange between devices. The illustrated network 90 is constituted 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 either wired or wireless, or a combination of these. And when the network 90 is an Internet network based on, for example, TCP / IP, the management device 10 and the terminal device 30 can transmit and receive information designating a communication partner based on the IP addresses set for each of them.

[0016] In addition, in the example shown in FIG. 1, each of the power supply terminal devices 60 is owned and managed by the owner of the parking lot or the like. That is, the owner and manager of the power supply system 1 and the owner and manager of the power supply terminal device 60 are different from each other.

[0017] Also, the location where the power supply terminal device 60 is provided is not particularly limited. That is, the power supply terminal device 60 may be provided in one parking lot. Alternatively, each of the power supply terminal devices 60 may be provided in a plurality of parking lots spaced apart from each other.

[0018] (Management device 10) FIG. 2 is a diagram for explaining a configuration example of the management device 10.

[0019] Next, a configuration example of the management device 10 will be described with reference to FIG. 2. The management device 10 includes a user management unit 110 that manages users, a power management unit 130 that manages the power supply terminal device 60, and a power supply management unit 150 that manages the power supply operation by the power supply terminal device 60.

[0020] 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 usage applications for the power supply terminal device 60, and a right management unit 117 that manages the right to supply power with the power supply terminal device 60.

[0021] 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.

[0022] 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 the designation of a user name and a password in the user registration process and outputs a user ID that is the identification information of the user.

[0023] The usage application reception unit 115 (an example of a reception unit) receives the user's login performed by the user operating the terminal device 30. Further, the usage application reception unit 115 receives a usage application for the power supply terminal device 60. In this usage application, application information such as the identification information of the user (that is, the user ID), the identification information of the power supply terminal device 60 that supplies power (the power supply device ID described later), and the usage time of the power supply service (that is, the power supply time) is received from the user. Note that the usage time includes information on the date of using the power supply service, the time when using the power supply service starts, and the time from when the power supply service starts until it ends (that is, the period). In addition, the service application reception unit 115 conducts payment, i.e., settlement, for the fee for receiving the power supply service. The fee here is set to change, for example, according to the power supply time. Also, the settlement is executed by well-known techniques such as payment by credit card.

[0024] The right management unit 117 manages the right to use the power supply service, i.e., the right to supply power using the power supply terminal device 60. Specifically, when the settlement by the service application reception unit 115 is completed, the right management unit 117 generates the right to receive the settled power supply service, i.e., the right of use. Also, when the power supply by the power supply terminal device 60 is completed, the right management unit 117 cancels the right of use. Then, along with the generation of the right of use, the right management unit 117 creates usage information for enabling the user to use the power supply service. The usage information is created based on the above-described application information. The usage information includes the identification information of the user who uses the power supply service, the identification information of the power supply terminal device 60 that supplies power, and the information on the usage time of the power supply service.

[0025] The power supply management unit 130 includes a power supply information management unit 131 that manages power supply information, and a management information output unit 135 that outputs the power supply information managed by the power supply information management unit 131.

[0026] The power supply information management unit 131 acquires and stores the power supply information, which is information for managing the power supply terminal device 60. Here, the power supply information includes the power supply device ID, which is the identification information of the power supply terminal device 60, the location information of the power supply terminal device 60, the usage history of the power supply terminal device 60, etc. Also, the power supply information includes the name and contact information of the owner of the power supply terminal device 60. Here, the contact information of the owner includes the owner's phone number, email address, etc.

[0027] The management information output unit 135 outputs the power supply information managed by the power supply 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. As a result, the owner of the power supply terminal device 60 can grasp the usage status of the power supply terminal device 60 he / she owns.

[0028] In addition, when a trouble occurs in the power supply terminal device 60 or the like, the management information output unit 135 notifies the administrator of the power supply system 1 and also notifies the owner of the power supply terminal device 60. As a result, the owner of the power supply terminal device 60 can quickly eliminate the trouble of the power supply terminal device 60. Here, for example, the management information output unit 135 outputs the usage history of the power supply terminal device 60 to the computer device (such as a smartphone, not shown) of the owner of the power supply terminal device 60 as character information such as an email or image information. 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 smartphone or the like. By outputting as voice information via a phone or the like, the possibility that the administrator forgets to check as in the case of character information or the like is reduced. As a result, the owner of the power supply terminal device 60 can more surely recognize the trouble and can eliminate the trouble of the power supply terminal device 60 more quickly.

[0029] The power supply management unit 150 includes an authentication unit 151 that performs user authentication and an energization processing unit 153 that performs a process of starting a power supply service for the authenticated user.

[0030] The authentication unit 151 performs authentication in response to an instruction from the terminal device 30. Although details will be described later, in this authentication, the power supply device ID of the power supply terminal device 60 or the like is used. The energization processing unit 153 (an example of the output unit) outputs an instruction for the power supply terminal device 60 to supply power to the device to the terminal device 30. Specifically, the energization processing unit 153 outputs the above-described usage information and status information for turning on the power of the power supply terminal device 60. Further, the energization processing unit 153 receives an energization end notification, which is a notification that the energization has ended, from the terminal device 30.

[0031] (Hardware Configuration of the Management Device 10) FIG. 3 is a diagram showing an example of the hardware configuration of the management device 10.

[0032] As shown in FIG. 3, the management device 10 includes a CPU 101, a RAM (Random Access Memory) 102, a ROM (Read Only Memory) 103, an HDD (Hard Disk Drive) 104, and a network I / F 105.

[0033] The CPU 101 realizes the above-described functions of the management device 10 by loading and executing various programs stored in the ROM 103 or the like into the RAM 102. The RAM 102 is a memory used as a working memory of the CPU 101 or the like. The ROM 103 is a memory that stores various programs and the like executed by the CPU 101. The HDD 104 is, for example, a magnetic disk device that stores power supply information of the power supply terminal device 60 and the like. The network I / F 105 transmits and receives various information to and from other devices via the network 90 (see FIG. 1).

[0034] Here, the program executed by the CPU 101 can be provided to the management device 10 in a state of being stored in a computer-readable recording medium such as a semiconductor memory. Further, the program executed by the CPU 101 may be downloaded to the terminal device 30 or the like via the management device 10. For example, a program for realizing the above-described functions of the management device 10 may be downloaded to the management device 10 as an application.

[0035] (Terminal device 30) FIG. 4 is a diagram for explaining a configuration example of the terminal device 30.

[0036] Next, a configuration example of the terminal device 30 will be described with reference to FIG. 4. The terminal device 30 includes an application management unit 31 that starts applications and the like, a usage application unit 33 that makes an application to use the power supply terminal device 60, an authentication unit 35 that performs authentication at the start of using the power supply terminal device 60, an image display unit 37 that presents information to the user, and a communication unit 39 that communicates with the power supply terminal device 60.

[0037] Here, the communication unit 39 performs BLE communication via a BLE I / F 313 (described later). The communication unit 39 has a wireless communication function. BLE communication is communication using one of the short-range wireless communication standards. To explain further, BLE communication refers to communication by Bluetooth Low Energy (registered trademark), which is one of the extended specifications of Bluetooth (registered trademark).

[0038] (Hardware configuration of the terminal device 30) FIG. 5 is a diagram showing a hardware configuration example of the terminal device 30.

[0039] As shown in FIG. 5, the terminal device 30 includes a CPU 301, a RAM 302, a ROM 303, a storage unit 304, an operation panel 305, a speaker 306, a microphone 307, a camera 308, a GPS sensor 309, a network I / F 312, and a BLE I / F 313.

[0040] The CPU 301 realizes each of the above functions of the terminal device 30 by loading various programs stored in the ROM 303 and the like into the RAM 302 and executing them. The RAM 302 is a memory used as a working memory of the CPU 301 and the like. The ROM 303 is a memory that stores various programs and the like executed by the CPU 301. The memory unit 304 is, for example, a flash memory that stores programs of various applications and various data used by the programs. The operation panel 305 is, for example, a touch panel that displays various information and receives operation inputs from the user.

[0041] The speaker 306 outputs various sounds including the received voice from the call destination. The microphone 307 acquires various sounds including the user's spoken voice. Note that in this embodiment, when the power supply terminal device 60 can transmit ultrasonic waves, the microphone 307 can receive the ultrasonic waves to realize ultrasonic communication with the power supply terminal device 60. The camera 308 includes a lens and an imaging element (image sensor) such as a CMOS (Complementary Metal - Oxide Semiconductor), and photographs a subject.

[0042] The GPS sensor 309 acquires a GPS (Global Positioning System) signal and acquires the position information of the terminal device 30. The network I / F 312 transmits and receives data to and from other communication devices. Here, the network I / F 312 communicates with the management device 10 etc. via the network 90 (see FIG. 1). The BLE I / F 313 has a BLE communication circuit (not shown), and performs BLE communication with the power supply terminal device 60 using this BLE circuit.

[0043] Here, the program (application) executed by the CPU 301 can be provided to the terminal device 30 etc. in a state of being stored in a computer - readable recording medium such as a semiconductor memory. Also, the program executed by the CPU 301 may be downloaded to the terminal device 30 etc. via the network 90. For example, a program that realizes the above - mentioned various functions of the terminal device 30 etc. may be downloaded to the terminal device 30 as an app.

[0044] (Power supply terminal device 60) FIG. 6 is a schematic perspective view of the power supply terminal device 60 of the present embodiment. FIG. 7 is a diagram showing a configuration example of the power supply terminal device 60 of the present embodiment.

[0045] As shown in FIG. 6, the power supply terminal device 60 includes 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 can supply power to a camping car CR (see FIG. 1) parked in the parking space by being connected via a power cable CA (see FIG. 1).

[0046] As shown in FIG. 7, the housing 601 includes an A / D converter 610 that converts an externally applied AC100V analog voltage into a digital signal, a control unit 630 that controls each component of the power supply terminal device 60, and a power 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 includes an LED 67 that emits light and a BLE I / F 679 that communicates.

[0047] 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. More specifically, the timer 651 starts measuring the elapsed time by receiving a signal from the control unit 630, and shuts off the power relay 650 when a predetermined time has elapsed. As a result, after a predetermined time has elapsed, the power supply to the camping car CR ends.

[0048] The LED 67 receives a control signal from the control unit 630 and is a light-emitting element that switches between lighting and extinguishing. The LED 67 notifies the user of the operating state of the power supply terminal device 60 according to the lighting mode. The LED 67 includes a first LED 671, a second LED 672, and a third LED 673 (see FIG. 6). For example, by lighting the first LED 671 red, the user is notified that power supply is in progress. Also, by lighting the second LED 672 green, the user is notified that the power supply has ended. Further, by lighting the third LED 673 yellow, the user is notified that the power supply terminal device 60 is in standby.

[0049] The BLE I / F 679 (an example of a communication unit) receives a control signal 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 uses this BLE circuit to perform BLE communication with the terminal device 30.

[0050] In the present embodiment, the communication range using BLE communication between the terminal device 30 and the power supply terminal device 60 is set to, for example, 30 meters. Accordingly, when BLE communication is possible between the terminal device 30 and the power supply terminal device 60, it can be determined that the terminal device 30 exists near the power supply terminal device 60. 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 at maximum according to the communication standard and the like.

[0051] The terminal of the power cable CA (see FIG. 1) is inserted into the power supply terminal 681. With the terminal of the power cable CA inserted, the power supply terminal 681 supplies power from the power relay 650 to the camping car CR via the power cable CA.

[0052] 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, for example, like the network I / F 312 of the terminal device 30. That is, the power supply terminal device 60 of the present embodiment is not connected to the network 90. For example, the power supply terminal device 60 does not have an IP address set, and for example, it cannot communicate information with the management device 10 via the network 90 by designating the management device 10 as the communication destination. 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 the communication destination.

[0053] On the other hand, the power supply terminal device 60 has a BLE I / F 679 and can communicate one-on-one with the terminal device 30 in a state where communication is established between the power supply terminal device 60 and the terminal device 30. However, the terminal device 30 cannot perform BLE communication with other communication devices such as other terminal devices in a state where communication is established between the terminal device 30 and 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 is configured so that it cannot communicate with two or more communication devices simultaneously.

[0054] (Operation of the power supply system 1) Next, the operation in the power supply system 1 will be described. The power supply system 1 performs a user registration operation in which the user acquires a user ID, a usage application operation in which the user applies in advance for the use of the power supply service in the power supply terminal device 60, and a power supply operation in which power is supplied to the camping car CR. Hereinafter, each of the user registration operation, the usage application operation, and the power supply operation will be described.

[0055] (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 an application to the terminal device 30 via the network 90. That is, the application is downloaded to the terminal device 30.

[0056] Next, when the user operates the terminal device 30, the application management unit 31 of the terminal device 30 transmits the user name and password 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 a 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.

[0057] (Usage application operation) At the time of applying for usage, when the user operates the terminal device 30, the application management unit 31 of the terminal device 30 executes a login process from the application. Then, the user operates the terminal device 30 to select a power supply terminal device 60 that receives the power supply service and specifies the usage time (i.e., the power supply time). This specification is received by the usage application reception unit 115 of the management device 10. Then, the usage application reception unit 115 calculates the usage fee according to the received power supply terminal device 60 and usage time and transmits it to the terminal device 30. Then, when the terminal device 30 is operated, the usage application reception unit 115 of the management device 10 executes the settlement. 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.

[0058] (Power supply operation) FIG. 8 is a flowchart showing the power supply operation of the power supply system 1. FIG. 9 is a flowchart showing the power supply operation of the power supply system 1. FIG. 10 is a diagram for explaining the image displayed on the terminal device 30. FIGS. 11(a) and 11(b) are diagrams for explaining the image displayed on the terminal device 30.

[0059] Referring to FIGS. 8 and 9, the power supply operation of the power supply system 1 will be described. Here, the user has completed an application for using the power supply service by communicating with the management device 10 via the terminal device 30.

[0060] For example, the user arrives at the parking lot where the power supply terminal device 60 selected in the application is installed. Then, the user approaches the power supply terminal device 60 while holding the terminal device 30. When the terminal device 30 is located within a predetermined distance range with respect to the power supply terminal device 60, the terminal device 30 receives the advertisement signal cast by the power supply terminal device 60 (S801). The terminal device 30 makes a connection request to the power supply terminal device 60 in response to the advertisement signal (S802). Then, BLE communication is established between the power supply terminal device 60 and the terminal device 30.

[0061] Next, in the terminal device 30, the authentication unit 35 generates a random value (S803). Then, the authentication unit 35 of the terminal device 30 transmits the generated random value to the power supply terminal device 60 (S804).

[0062] The control unit 630 of the power supply terminal device 60 generates a session key based on the random value obtained 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 value generated for each use of the user's power supply service and is used only for one use of the power supply service.

[0063] Furthermore, the control unit 630 of the power supply terminal device 60 generates a power supply terminal MAC value, which is a MAC value calculated by the power supply terminal device 60, from 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 authentications, and the session key generated in S805 (S806). The MAC (Massage Authentication Code) value is a value for protecting and authenticating the integrity of information by enabling a configuration that holds a 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 constitute a common key relationship.

[0064] 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 the power supply terminal MAC value.

[0065] 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 the power supply device ID, key version information, count information, the power supply terminal MAC value, the generated random value, and the user ID.

[0066] The authentication unit 151 of the management device 10 generates a power supply terminal key using the master key it holds and the power supply device ID of the power supply terminal device 60 obtained via the terminal device 30. Furthermore, the authentication unit 151 of the management device 10 generates a session key using 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 obtained 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). The authentication by the authentication unit 151 of the management device 10 is performed by verifying whether the generated MAC value for verification matches the power supply terminal MAC value acquired via the terminal device 30.

[0067] After that, when the power supply processing unit 153 of the management device 10 determines that the authentication result is correct by the authentication unit 151, it creates status information instructing to turn on the power of 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). Then, the management device 10 transmits the authentication information to the terminal device 30 (S812). The authentication information transmitted by the management device 10 includes the count information, the status information, and the generated management MAC value.

[0068] Furthermore, when the power supply processing unit 153 of the management device 10 determines that the authentication result is correct by the authentication unit 151, it refers to the usage information corresponding to the acquired user ID (S813). Then, the power supply processing unit 153 of the management device 10 transmits the usage information and the time information, which is 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.

[0069] The terminal device 30 receives an operation from the user to start power supply by the power supply terminal device 60 (S815). Specifically, the image display unit 37 of the terminal device 30 displays a reception image 400 (see FIG. 10) for receiving the user's operation to start power supply by the power supply terminal device 60 according to the usage information acquired from the management device 10. This reception image 400 can be regarded as an image displayed on the operation panel 305 on the condition that the terminal device 30 is located within a predetermined distance range from the power supply terminal device 60. The predetermined distance can be exemplified by, for example, the distance at which communication by BLE communication is possible.

[0070] As shown in FIG. 10, on the reception image 400 displayed on the operation panel 305 of the terminal device 30, position information of the power supply terminal device 60 and power supply pole information 405 that can identify the power supply terminal device 60, and a message image 406 prompting the user to operate are displayed. Further, on the reception image 400, a permission image 407 for receiving an instruction to permit starting power supply and a restriction image 408 for receiving an instruction to restrict starting power supply are displayed.

[0071] Then, when the terminal device 30 receives an operation by the user on the permission image 407, that is, an operation permitting the start of power supply from the user, as shown in FIG. 8, the terminal device 30 transmits start information for starting power supply at the power supply terminal device 60 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.

[0072] 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, the count information, and the status information acquired via the terminal device 30. Then, the authentication by the control unit 630 of the power supply terminal device 60 is performed by verifying whether the generated MAC value for verification matches the management MAC value acquired via the terminal device 30.

[0073] Thus, in the power supply system 1 of the present embodiment, by performing verification using a common key as described above, mutual authentication among the management device 10, the terminal device 30, and the power supply terminal device 60 is performed via the terminal device 30. As a result, in the power supply system 1, even if direct information transmission and reception are not performed between the management device 10 and the power supply terminal device 60, security is ensured by mutual authentication via the terminal device 30.

[0074] After that, when 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 acquired via the terminal device 30 (S818). Note that the power supply terminal device 60 cannot communicate with the outside except when 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 accurate time. Therefore, in this embodiment, the power supply terminal device 60 corrects the time of the timer 651 when communicating with the terminal device 30.

[0075] Then, the control unit 630 of the power supply terminal device 60 operates the power relay 650 to start energization (S819). Also, the timer 651 starts timing (S820). As described above, the power supply terminal device 60 of this 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.

[0076] Next, the power supply terminal device 60 transmits a power-on notification to the terminal device 30 via BLE communication (S821). Then, the image display unit 37 of the terminal device 30 that has received the power-on notification displays a power-on image 401 (see FIG. 11(a)) indicating that power is being supplied on the operation panel 305 of the terminal device 30 (S822). Furthermore, the terminal device 30 notifies the management device 10 of the information that power supply has started, together with the device ID and the user ID, via the network 90 (S823).

[0077] As described above, in the power supply system 1 of this embodiment, when the user holds the terminal device 30, is located near the power supply terminal device 60 to be used, and only operates the allowable image 407 (see FIG. 10) displayed on the operation panel 305 of the terminal device 30, the power supply terminal device 60 can be put into a power supply-enabled state. Then, based on the user's usage application, the usage time elapses.

[0078] Next, the timer 651 detects the end of the usage time (S824). Then, the power relay 650 of the power supply terminal device 60 ends the energization (S825). Further, the power supply terminal device 60 transmits an energization 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 energization end notification displays an end image 403 (see FIG. 11(b)) indicating that the power supply has ended (S827). Further, the terminal device 30 transmits an energization end notification to the management device 10 via the network 90 (S828). And in the management device 10, the usage right is erased (S829).

[0079] As described above, in the power supply system 1 of the present embodiment, for a power supply terminal device 60 that cannot communicate with the management device 10 via the network 90, a power supply instruction is given based on the exchange of information via the terminal device 30. And since the power supply terminal device 60 does not require a device for performing upper-level communication via the network 90, for example, the installation cost is reduced.

[0080] In the example of the power supply system 1 in the above-described embodiment, for example, in a usage application received by the usage application reception unit 115, the user designates in advance a power supply terminal device 60 that performs power supply, but it is not limited to this mode. For example, the management device 10 generates a usage right that enables the use of any one of a plurality of power supply terminal devices 60 for the user who has made a usage application. On the other hand, the user possesses the terminal device 30 and is located near the power supply terminal device 60 that the user wishes to use. In this case, the user can use, for example, the power supply terminal device 60 in which the third LED 673 indicating that it is in a standby state is lit yellow by checking the LED 67 (see FIG. 6) of the power supply terminal device 60. And in the power supply system 1, mutual authentication and transmission / reception of usage information among the power supply terminal device 60, the terminal device 30, and the management device 10 are performed by BLE communication between the power supply terminal device 60 and the terminal device 30 and communication via the network 90 between the terminal device 30 and the management device 10. Thereby, the power supply system 1 can enable the user to use the power supply service.

[0081] <Modification Example> Here, the 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 at the end of the power supply service.

[0082] For example, the power supply terminal device 60 specifies a predetermined time (e.g., 5 minutes before the end) before the power supply end time based on the time measured by the timer 651. Then, the power supply terminal device 60 transmits a pre - end notification to the terminal device 30 in advance to notify that the power supply will end via BLE communication. Further, the terminal device 30 transmits the received pre - end 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 pre - end notification.

[0083] As shown in FIG. 12, the image displayed on the operation panel 305 of the terminal device 30 includes a warning image 501 that warns that the usage time is about to end and a message image 502 that prompts an extension of the power supply time. Further, the image displayed on the operation panel 305 of the terminal device 30 includes an extension button image 503 for receiving an instruction to extend the power supply time from the user and an end button image 504 for receiving an acceptance from the user to end at a predetermined time without extending.

[0084] When the user operates 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 above - described usage application procedure.

[0085] <Modification Example> Next, the update process of the power supply terminal device 60 will be described. FIG. 13 is an operation flow of the program update of the power supply terminal device 60 of the present embodiment.

[0086] As described above, in order to mutually authenticate 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 perspective of security, the management device 10 updates the version of the master key. Accordingly, 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, there may be a case where the power supply terminal device 60 needs to update the program used by the control unit 630.

[0087] As shown in FIG. 13, the management device 10 determines whether it is necessary to update the program of the power supply terminal device 60 (S1301). When the management device 10 determines that it is necessary to update the program (YES in S1301), it identifies the power supply terminal device 60 to be updated (S1302). Further, the management device 10 refers to the application information for the identified power supply terminal device 60 (S1303).

[0088] Then, the management device 10 determines whether there is a user application for the target power supply terminal device 60 (S1304). When there is a user application for the target power supply terminal device 60 (YES in S1304), the management device 10 notifies the user to obtain consent to cooperate in updating the program of the power supply terminal device 60 (S1305). Note that the management device 10 can present a consideration such as providing the power supply service for free to the user who cooperates in the update.

[0089] Next, the management device 10 determines whether the user has agreed to cooperate in the update (S1306). This agreement can be determined, for example, by displaying a predetermined image on the operation panel 305 of the terminal device 30 and based on the user's operation on the operation panel 305. And when the user agrees to cooperate in the update (YES in S1306), for example, when the terminal device 30 is located near the power supply terminal device 60 that is the target, the management device 10 transmits the information of the update program to the terminal device 30 (S1307). Further, for example, in a state where 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 the update of the program to the terminal device 30 (S1308).

[0090] Then, after the above-described mutual authentication is executed between the power supply terminal device 60 and the management device 10 via the terminal device 30, the power supply terminal device 60 acquires the update program and the update permission information from the terminal device 30 (S1309). In the power supply terminal device 60, the control unit 630 is updated by the update program received from the terminal device 30 (S1310). In the above manner, the management device 10 updates the program of the power supply terminal device 60 via the user's terminal device 30.

[0091] Note that when the management device 10 determines that the program update is not necessary (NO in S1301), when there is no user application for using the target power supply terminal device 60 (NO in S1304), or when the user does not agree to cooperate in the update (NO in S1306), the process ends.

[0092] Here, in the above-described example, it is premised that the user has made a reservation for using the power supply terminal device 60 that is the target of the program update, but it is not limited to this example. Even if there is no user application for using the target power supply terminal device 60, the user who uses this service may be asked to cooperate in the update of the program of the power supply terminal device 60.

[0093] <Modification Example> Next, the 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 going through the terminal device 30. On the other hand, in the power supply terminal device 60, an error such as a failure or a malfunction may occur. In such a case, the management device 10 cannot directly collect error information from the power supply terminal device 60.

[0094] 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 in the vicinity of its own device. For example, the power supply terminal device 60 establishes BLE communication with the terminal device 30 in the vicinity and obtains the consent of the user to transmit the error information to the management device 10. Even in this case, a consideration such as providing the power supply service free of charge may be given to the user. Then, the power supply terminal device 60 transmits the error information to the terminal device 30 of the user who has obtained consent. Further, the terminal device 30 transmits the acquired error information to the management device 10 via the network 90.

[0095] In this way, in the power supply system 1 of the present embodiment, the management device 10 can collect the error information generated in the power supply terminal device 60.

[0096] <Modification example> In the above description, it has been described that the terminal device 30 and the power supply terminal device 60 perform BLE communication, but it is not limited to this as long as communication is performed between the terminal device 30 and the power supply terminal device 60. For example, instead of BLE communication or in addition to BLE communication, other wireless communications such as ultrasonic communication and Wi-Fi communication (registered trademark, Wireless Fidelity) may be used. For example, either ultrasonic communication or wireless communication other than ultrasonic may be started first, or ultrasonic communication and wireless communication other than ultrasonic may be started simultaneously.

[0097] Alternatively, 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, a configuration may be adopted in which two-way communication is performed by ultrasonic waves between the terminal device 30 and the power supply terminal device 60. In this configuration, a microphone (not shown) is provided in the power supply terminal device 60. Then, the microphone (not shown) of this power supply terminal device 60 receives the ultrasonic signal transmitted from the terminal device 30.

[0098] <Other application examples of the service> Furthermore, the devices powered by the power supply system 1 of the present embodiment are not limited to the camping car CR. For example, the devices powered by the power supply system 1 may be vehicles such as electric vehicles, electric motorcycles, electric carts, and electric bicycles. Furthermore, the devices powered by the power supply system 1 may be smartphones, tablet terminals, portable rechargeable batteries, etc.

[0099] Also, the power supply terminal device 60 etc. included in the power supply system 1 are devices that provide a power supply service to the user by the user paying a fee, but the configuration of the power supply system 1 may be used for the use of devices that provide other services to the user.

[0100]

[0101] ​In the above-described system, the management device 10 sends authentication information for mutual authentication to the control unit of the washing machine via the terminal device 30. Further, the management device 10 sends usage information for enabling the use of the washing machine to the control unit of the washing machine via the terminal device 30. This usage information includes information on the usage time of the service based on the user's usage application. Then, the washing machine controls the user's usage based on the acquired usage time information and the timekeeping of a built-in timer (not shown).

[0102] In addition, examples of other services of the power supply service include not only the above-described coin laundry, but also various services such as coin parking, shower rooms and toilets at campsites, and car sharing. Also in this case, even if the device providing the service cannot directly communicate with the management device 10 via the network 90, it is sufficient to exchange authentication information for mutual authentication and usage information for enabling the use of the service via the terminal device 30. Also in this case, the usage information includes usage information regarding the time when the user uses the service. Then, the service providing device providing the service may control the user's use of the service based on the acquired usage time information and the timekeeping of a built-in timer (not shown).

[0103] Also, in the above description, payment by credit card has been described, but it is not limited thereto. In the power supply system 1, for example, well-known payment means such as contactless IC cards, QR code (registered trademark) payment, and barcode payment can be adopted.

[0104] Also, in the above description, the operating state of the power supply terminal device 60 is shown by the lighting mode of the LED 67 (see FIG. 6), but it is not limited thereto. For example, the operating state of the power supply terminal device 60 may be shown by displaying an image or the like on the terminal device 30. Here, the operating state of the power supply terminal device 60 includes in use (remaining use time), unpaid (unpaid time), reservation available (reservation use start time), unavailable (failure type, estimated recovery time), and the like.

[0105] Further, the power supply system 1 may be provided with a printing device capable of printing information related to power supply, such as the power supply end time, on a piece of paper (so-called seal). By sticking this seal on the window of the electric vehicle, for example, an administrator of the power supply terminal device 60 other than the user can grasp the power supply end time and the like.

[0106] <Second Embodiment> FIG. 14 is a schematic diagram of the service providing system 2 according to the second embodiment. In the description of the second embodiment, the same components as those in the above-described embodiments and modified examples are denoted by the same reference numerals, and the detailed description thereof is omitted.

[0107] As shown in FIG. 14, the service providing system 2 according to the second embodiment provides a parking service using a parking facility 700 where the user's vehicle 100 is parked. The parking facility 700 is provided with a parking space 710 which is a place for parking the vehicle 100, a bench 720 where the user sits, for example, and a wheel stopper 730 for the vehicle 100.

[0108] The service providing system 2 includes a management device 10 (see FIG. 1), a terminal device 30 (see FIG. 1), a power supply terminal device 60, a parking facility 700, a parking terminal device 71 for managing parking, a sensor device 73 for detecting the vehicle 100, and a warning light 75 that emits light. The power supply system 1 provides a power supply service to the user using the power supply terminal device 60, and provides a parking service to the user using the parking terminal device 71.

[0109] The management device 10 according to the second embodiment enables a user having the terminal device 30 to park the vehicle 100 in the parking space 710 via the parking terminal device 71. The management device 10 according to the second embodiment has the same functions as those in the case of realizing the power supply service, and realizes the parking service in the same manner as the power supply service.

[0110] The management device 10 of the second embodiment receives applications for using the parking facility 700 and manages the right to use the parking facility 700. Further, the management device 10 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 user can use the parking facility 700. Then, the parking terminal device 71 of the second embodiment performs mutual authentication with the management device 10 via the terminal device 30. Further, when the mutual authentication is correct, the parking terminal device 71 provides a parking service using the parking facility 700 within the range of the usage time based on the usage information.

[0111] The terminal device 30 of the second embodiment enables the user to use the parking service in the same manner as the use of the power supply service.

[0112] The parking terminal device 71 is not connected to the network 90 (see FIG. 1) in the same manner as the power supply terminal device 60. On the other hand, the parking terminal device 71 can communicate one-on-one with the terminal device 30 in a state where communication is established with the terminal device 30. 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. Further, the parking terminal device 71 makes the user able to use the parking space 710 or unable to use the parking space 710 based on the usage information created in response to the reservation of the parking facility 700 made by the user. The parking terminal device 71 of the second embodiment controls the availability of using the parking facility 700 using the warning lamp 75.

[0113] The parking terminal device 71 is electrically connected to the sensor device 73 and the warning lamp 75, respectively. Then, the parking terminal device 71 controls the sensor device 73 or acquires a detection signal from the sensor device 73. Further, the parking terminal device 71 controls the operation of the warning lamp 75.

[0114] The sensor device 73 includes a light emitting unit 731 that emits infrared rays and a light receiving unit 733 that receives the infrared rays emitted by the light emitting unit 731. The sensor device 73 sends light emission information regarding the light emission of the light emitting unit 731 and light reception information regarding the light reception of the light receiving unit 733 to the parking terminal device 71. Then, the sensor device 73 determines whether or not the vehicle 100 is parked in the parking space 710. For example, when the vehicle 100 is parked in the parking space 710, the infrared rays emitted from the light emitting unit 731 are blocked by the vehicle 100 and are not received by the light receiving unit 733. On the other hand, when the vehicle 100 is not parked in the parking space 710, the infrared rays irradiated from the light emitting unit 731 are received by the light receiving unit 733.

[0115] Also, the light emitting unit 731 is provided at a corner in the parking space 710. On the other hand, the light receiving unit 733 is provided at another corner in the parking space 710. In the second embodiment, the light emitting unit 731 and the light receiving unit 733 are respectively arranged diagonally in the parking space 710. And 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 (the dashed-dotted line in FIG. 14). In the sensor device 83, by arranging the light emitting unit 731 and the light receiving unit 733 diagonally, a detection range is set in most of the vertical and horizontal directions of the parking space 710. Thereby, the sensor device 83 makes it easier to detect the presence or absence of the vehicle 100 regardless of the size of the vehicle 100 parked in the parking space 710.

[0116] The warning lamp 75 is provided, for example, on the side of the parking space 710. Also, the warning lamp 75 is provided near the power supply terminal device 60 and the parking facility 700. Further, the warning lamp 75 is installed above the parking space 710. And the warning lamp 75, for example, rotates and emits light. Specifically, the warning lamp 75 reflects the light of the light source by a reflecting mirror that rotates around the light source and emits light. Also, for the warning lamp 75, for example, one that emits red light can be used.

[0117] The warning light 75 emits light to notify the user that the parking space 710 cannot be used. The warning light 75 of the second embodiment psychologically acts to make it difficult to park the vehicle 100 in the parking space 710, for example, by emitting red light while rotating. On the other hand, the warning light 75 turns off to notify the user that the parking space 710 is available. That is, the warning light 75 makes the user think that it is okay to park the vehicle 100 in the parking space 710 when it is turned off.

[0118] In the second embodiment, the parking terminal device 71 is an example of the service providing device. The warning light 75 is an example of the notification means. The sensor device 73 is an example of the detection means.

[0119] Subsequently, the operation of the service providing system 2 of the second embodiment will be described. FIG. 15 is an explanatory diagram of the operation of the service providing system 2 of the second embodiment.

[0120] 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 the sensor device 73 has detected for a specific time (for example, 10 seconds or more) (S1501). Here, in the sensor device 73, the state where the infrared ray emitted by the light emitting unit 731 is not received by the light receiving unit 733 is the state of detecting an object.

[0121] When the sensor device 73 has detected for a specific time or more (YES in S1501), the parking terminal device 71 starts the operation of emitting light of the warning light 75 (S1502). In the second embodiment, the warning light 75 emits red light.

[0122] Thereafter, the parking terminal device 71 determines whether the mutual authentication with the management device 10 via the terminal device 30 is correct (S1503). 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 operation of emitting light of the warning light 75 (S1504).

[0123] After that, 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 usage information. This usage time is set when the user makes a reservation or the like, for example, several hours to 24 hours, etc. Then, the parking terminal device 71 determines whether the usage time of the parking service has ended based on the usage information of the parking service (S1505). And when the parking terminal device 71 determines that the parking service has ended (YES in S1505), it ends a series of processes.

[0124] In addition, even after the usage time has ended, if the vehicle 100 is parked in the parking space 710, via S1501 and S1502, the parking terminal device 71 operates the warning light 75. 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.

[0125] Here, if the detection by the sensor device 73 in S1501 is not for a predetermined time or more (NO in S1501), the parking terminal device 71 does not operate the warning light 75. For example, there may be a case where people or animals temporarily cross the parking space 710, such as passing through the parking space 710. Operating the warning light 75 even in such a case would cause unnecessary alertness to people who have temporarily passed through. Therefore, in the service providing system 2 of the second embodiment, the warning light 75 is operated on the condition that the sensor device 73 performs detection for a predetermined time or more.

[0126] In addition, if the mutual authentication in S1503 is incorrect (NO in S1503), it returns to S1502 and the operation of the warning light 75 continues. As a result, when a user who has not applied for the parking service parks the vehicle 100 in the parking space 710, the emission of the warning light 75 prompts the user to leave the parking space 710. Also, if it is determined at S1505 that the usage time has not ended (NO at S1505), the determination of the passage of the usage time continues until the usage time has passed. That is, until the usage time reserved by the user for the parking space 710 has passed, the parking space 710 can be used without operations such as the warning light 75 emitting light occurring.

[0127] Here, conventionally, for example, parking management has been performed by a gate provided at the entrance of the parking space 710 that controls the entry and exit of the vehicle 100. Also, conventionally, for example, parking management has been performed by a flap plate or the like provided on the ground of the parking space 710 that restricts or enables the movement of the vehicle body and tires. Thus, conventionally, the parking of the vehicle 100 in the parking space 710 has been managed by the structure itself such as a gate or a flap plate. In contrast, in the service providing system 2 of the second embodiment, parking management is performed by controlling the emission of the warning light 75. Thus, in the service providing system 2 of the second embodiment, when performing parking management, for example, it is not essential to install a special structure in the parking space 710.

[0128] Also, the service providing system 2 of the second embodiment may include a speaker device. And in the service providing system 2, along with the emission of the warning light 75, a warning sound such as a buzzer may be output by the speaker device. Specifically, when the sensor device 73 detects that the vehicle 100 is parked in the parking space 710, a sound is output from the speaker device in conjunction with the emission of the warning light 75. Thereafter, mutual authentication is performed between the management device 10 and the parking terminal device 71 via the terminal device 30, and when the warning light 75 turns off, the output of the sound from the speaker device is stopped. Thus, the availability of the parking space 710 may be indicated by both a warning by the light of the warning light 75 and a warning by the sound from the speaker device. Note that the service providing system 2 may notify the availability of the parking space 710 only by the speaker device instead of the warning light 75.

[0129] 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 of the user on the screen of the terminal device 30, it may be displayed that the warning lamp 75 that was lit goes out.

[0130] <Third Embodiment> FIG. 16 is a schematic diagram of a service providing system 3 of the third embodiment. In the description of the third embodiment, the same components as those in the other embodiments and modification examples described above are denoted by the same reference numerals, and the detailed description thereof is omitted.

[0131] As shown in FIG. 16, in the service providing system 3 of the third embodiment, a service that allows use of a toilet, a shower, and a dressing room is provided using a facility 800 used by a user. The facility 800 includes a toilet room 810 where toilets are provided, a dressing room 820 used when changing clothes, a shower room 830 where showers are provided, a corridor 840 connecting to each room, and a management room 850 for a manager. Further, the facility 800 has a main door 880 provided at an entrance 860 through which users using the facility 800 enter and exit. In addition, in the facility 800 of the third embodiment, a door is provided for each room. Further, the management room 850 has a back door 891 that can be opened by the manager and a communication door 892.

[0132] The service providing system 3 of the third embodiment includes a management device 10 (see FIG. 1), a terminal device 30 (see FIG. 1), a facility 800, and a service terminal device 81 that manages the facility 800. The service providing system 3 also includes an electronic lock 82 that locks the main door 880, a sensor device 83 that detects a user, an outdoor display lamp 84 provided outside the facility 800 and emitting light, an indoor display lamp 85 provided inside the facility 800 and emitting light, and an operation panel 86 operated by the manager.

[0133] The management device 10 of the third embodiment enables a user who possesses the terminal device 30 to use the toilet room 810, the changing room 820, and the shower room 830 via the service terminal device 81. The management device 10 of the third embodiment has the same functions as those in the case of realizing the power supply service, and realizes the utilization service of the facility 800 in the same manner as the power supply service.

[0134] The management device 10 of the third embodiment receives an application for using the facility 800 and manages the right to use the facility 800. Further, the management device 10 of the third embodiment manages the facility information for managing the facility 800 and outputs the usage information regarding the use of the facility 800. Note that the usage information includes time information regarding the time when the user can use the facility 800. Then, the service terminal device 81 of the third embodiment performs mutual authentication with the management device 10 via the terminal device 30. Furthermore, when the mutual authentication is correct, the service terminal device 81 provides the service using the facility 800 within the range of the usage time based on the usage information.

[0135] The terminal device 30 of the third embodiment enables the user to use the service using the facility 800 in the same manner as the use of the power supply service.

[0136] The service terminal device 81 is not connected to the network 90, similar to the power supply terminal device 60. On the other hand, the service terminal device 81 can perform one-to-one communication with the terminal device 30 in a state where communication is established between the service terminal device 81 and the terminal device 30. The service terminal device 81 of the third embodiment can exchange information with the management device 10 via the terminal device 30.

[0137] Then, the service terminal device 81 performs mutual authentication with the management device 10 via the terminal device 30. Furthermore, the service terminal device 81 makes the user able to use the facility 800 or unable to use the facility 800 based on the usage information created in response to the reservation of the facility 800 made by the user. The service terminal device 81 of the third embodiment controls the availability of using the facility 800 using the electronic lock 82.

[0138] The service terminal device 81 is electrically connected to the electronic lock 82, the sensor device 83, the outdoor display lamp 84, and the indoor display lamp 85, respectively. And the service terminal device 81 controls the electronic lock 82, the sensor device 83, the outdoor display lamp 84, and the indoor display lamp 85, respectively. Also, the service terminal device 81 receives a detection signal from the sensor device 83.

[0139] The electronic lock 82 locks or unlocks the main door 880 according to the energized state. The energized state of the electronic lock 82 is controlled by the service terminal device 81. The electronic lock 82 of the present embodiment locks the main door 880 in the energized state. And when the electronic lock 82 locks the main door 880, the user outside cannot use the facility 800. On the other hand, when the electronic lock 82 unlocks the main door 880, the user outside can use the facility 800.

[0140] The electronic lock 82 of the present embodiment unlocks the main door 880 according to the control from the service terminal device 81 when the mutual authentication between the service terminal device 81 and the management device 10 is correct. Also, when a predetermined time (for example, 30 seconds) has elapsed after the service terminal device 81 unlocks the electronic lock 82, the electronic lock 82 locks the main door 880 based on the control from the service terminal device 81. Furthermore, the electronic lock 82 unlocks the main door 880 when a user is detected by the sensor device 83.

[0141] The sensor device 83 detects the presence or absence of a user in the corridor 840. The sensor device 83 detects the presence or absence of a user by receiving infrared rays emitted from the user's body. In particular, the sensor device 83 of the present embodiment is provided near the entrance / exit 860 in the corridor 840. And the sensor device 83 detects a user near the main door 880. When the sensor device 83 detects a user, it sends detection information to the service terminal device 81.

[0142] The outdoor display lamp 84 emits light or goes out according to the state of the electronic lock 82. The outdoor display lamp 84 of this embodiment emits green light when the electronic lock 82 unlocks the main door 880. On the other hand, when the electronic lock 82 locks the main door 880, the outdoor display lamp 84 goes out as a mode indicating that it is locked. In this way, the outdoor display lamp 84 notifies the user of the unlocking and locking states of the main door 880 by the electronic lock 82.

[0143] The indoor display lamp 85 changes its emission color according to the state of the electronic lock 82. The indoor display lamp 85 of this embodiment emits green light as a color indicating that it is unlocked when the electronic lock 82 unlocks the main door 880. On the other hand, when the electronic lock 82 locks the main door 880, the indoor display lamp 85 emits red light different from green as a color indicating that it is locked. In this way, the indoor display lamp 85 notifies the user of the unlocking and locking states of the main door 880 by the electronic lock 82.

[0144] The operation panel 86 receives an operation to turn off the power supply to the electronic lock 82. For example, when the administrator wants to unlock the main door 880, by operating the operation panel 86, the power supply to the electronic lock 82 is turned off. Thereby, the main door 880 can be opened. In addition, the operation panel 86 is linked with disaster prevention facilities such as a fire alarm (not shown). Then, for example, when the fire alarm operates, the operation panel 86 turns off the power supply to the electronic lock 82 and unlocks the main door 880.

[0145] In the second embodiment, the service terminal device 81 is an example of a service providing device. The outdoor display lamp 84 is an example of a notification means. The sensor device 83 is an example of a detection means.

[0146] Subsequently, the operation of the service providing system 3 of the third embodiment will be described. FIG. 17 is an explanatory diagram of the operation of the service providing system 3 of the third embodiment.

[0147] As shown in FIG. 17, in the service providing system 3, the service terminal device 81 determines whether the mutual authentication with the management device 10 is correct via the terminal device 30 (S1701). Then, when it is determined that the mutual authentication with the management device 10 is correct (YES in S1701), the service terminal device 81 determines whether the usage time condition of the service is satisfied based on the usage information (S1702). When the usage time condition of the service is satisfied (YES in S1702), the service terminal device 81 unlocks the electronic lock 82 (S1703).

[0148] Furthermore, along with the unlocking of the electronic lock 82, the service terminal device 81 turns on the outdoor display lamp 84 (S1704). In the third embodiment, the outdoor display lamp 84 lights up in green. In this way, the outdoor display lamp 84 notifies the user that the main door 880 has been unlocked. Also, the user can enter the facility 800 when the main door 880 is unlocked. Then, the user can use the toilet room 810, the dressing room 820, and the shower room 830. Also, the service terminal device 81 turns on the indoor display lamp 85 (S1705). The indoor display lamp 85 in the third embodiment lights up in green. In this way, the indoor display lamp 85 notifies the user inside the facility 800 that the main door 880 has been unlocked.

[0149] Thereafter, the service terminal device 81 determines whether a predetermined time has elapsed since the electronic lock 82 was unlocked (S1706). When the predetermined time has elapsed (YES in S1706), the service terminal device 81 locks the main door 880 with the electronic lock 82 (S1707).

[0150] Furthermore, with the main door 880 locked by the electronic lock 82, the outdoor indicator light 84 turns off (S1708). Also, with the main door 880 locked by the electronic lock 82, the indoor indicator light 85 turns on red (S1709). In this way, the indoor indicator light 85 notifies the user inside the facility 800 that the main door 880 is locked. For example, when the indoor indicator light 85 is on red, the user recognizes that the main door 880 is locked. Based on this recognition, the user can use facilities such as the shower room 830 inside the facility 800.

[0151] Also, the sensor device 83 detects the user in the corridor 840 (S1710). When the user is detected by the sensor device 83 (YES at S1710), the electronic lock 82 unlocks the main door 880 (S1703). In this way, when there is a user in the corridor 840 of the facility 800, the electronic lock 82 is unlocked when the user is detected by the sensor device 83. That is, a user trying to go outside the facility 800 can open the main door 880.

[0152] Note that after the electronic lock 82 is unlocked, the outdoor indicator light 84 turns on green with the unlocking of the main door 880 by the electronic lock 82 (S1704). Also, the indoor indicator light 85 turns on green with the unlocking of the main door 880 by the electronic lock 82 (S1705). Furthermore, when a predetermined time has elapsed since the unlocking by the electronic lock 82 (YES at S1706), the electronic lock 82 is locked again (S1707). After the electronic lock 82 is locked, the outdoor indicator light 84 turns off with the locking of the main door 880 by the electronic lock 82 (S1708). Also, the indoor indicator light 85 turns on red with the locking of the main door 880 (S1709). In this way, when there is no user in the corridor 840 of the facility 800, that is, when the user has gone outside the facility 800, the main door 880 is locked.

[0153] And, if the user who has left facility 800 is within the usage time specified in the facility 800 usage application previously made to management device 10, mutual authentication between service terminal device 81 and management device 10 is correctly performed via terminal device 30. That is, the user who possesses terminal device 30 can unlock main door 880 with electronic lock 82 if it is within the usage time, and can use facility 800 any number of times.

[0154] Note that if mutual authentication is incorrect in S1701 (NO in S1701), the process returns to S1701 again, and the determination as to whether mutual authentication is correct continues to be made. Also, if the usage time condition is not satisfied in S1702 (NO in S1702), the process ends. In this case, the usage time based on the user's usage application has ended, and the user is in a state where they cannot use facility 800. Furthermore, if the predetermined time has not elapsed since unlocking in S1706 (NO in S1706), the process returns to S1706 again, and the determination regarding the elapse of time since unlocking continues to be made. Also, if the user is not detected by sensor device 83 in S1710 (NO in S1710), the process returns to S1710 again, and the determination of user detection by sensor device 83 continues to be made.

[0155] <Fourth Embodiment> FIG. 18 is a schematic diagram of service providing system 4 of the fourth embodiment. Note that in the description of the fourth embodiment, the same reference numerals are given to configurations similar to those of the other embodiments and modification examples described above, and detailed descriptions thereof are omitted.

And the service terminal device 91 controls the solenoid valve 92, the outdoor indicator light 93, and the indoor indicator light 94 respectively.

[0164] The solenoid valve 92 controls the water supply and cut-off from the supply pipe that supplies cold water or hot water to the shower facility 910 according to the energized state. The solenoid valve 92 is controlled by the service terminal device 91 for its energized state. And the solenoid valve 92 makes the shower facility 910 available for the user by opening the supply pipe to supply water to the shower facility 910. On the other hand, the solenoid valve 92 makes the shower facility 910 unavailable for the user by closing the supply pipe to cut off the water. And the solenoid valve 92 of the present embodiment enables water supply to the shower facility 910 in response to the control from the service terminal device 91 when the mutual authentication between the service terminal device 91 and the management device 10 is correct.

[0165] The outdoor indicator lamp 93 lights up or goes out according to the state of the solenoid valve 92. The outdoor indicator lamp 93 of the present embodiment lights up green when the solenoid valve 92 enables water supply. On the other hand, the outdoor indicator lamp 93 goes out when the solenoid valve 92 is shutting off water. In this way, the outdoor indicator lamp 93 notifies the user of the water supply and shut-off states of the shower facility 910 by the solenoid valve 92.
