(Embodiment 1)
≪Specific mode of stand-alone charging device≫
A specific embodiment of the stand-alone charging device according to the present invention will be described.
FIG. 1 is an external perspective view showing a stand-alone charging stand in this embodiment. The charging stand corresponds to a specific example of the stand-alone charging device according to the present invention.
The charging stand 10 shown in FIG. 1 is provided with a solar panel 12 at the upper end of a support column 11 standing in the vertical direction. Further, the storage battery 13, the four charging boxes 15 a to 15 d, the LED illumination 16, and the guide plate 17 are attached to and supported by the column 11.

The charging stand 10 stores the power generated by the solar panel 12 in the storage battery 13. Each of the four charging boxes 15a to 15d has a cover that can be opened and closed with an observation window and a charging terminal 25T that can be charged by connecting a portable communication terminal such as a mobile phone.
When the user opens the cover of any of the charging boxes 15a to 15d, the cable with the charging terminal 25T at the tip is exposed. The charging terminal 25T can be charged by connecting to a terminal of a mobile communication terminal held by the user.

The above-mentioned viewing window is for the user to visually recognize which of the charging boxes 15a to 15d is in use and which is not in use, and to allow the user to check the state during charging. belongs to.
The ring-shaped holes on the near side of the charging boxes 15a to 15d are drink holders.

The LED illumination 16 illuminates the guide plate 17 and the charging boxes 15a to 15d so as to be easily used at night. The guide plate 17 displays identification information for distinguishing the charging station 10 from other charging stations and further distinguishing the charging boxes 15a to 15d. In addition to the identification information, the guide plate 17 may display a description of a usage procedure or the like, or may display guidance for nearby facilities or the like.
Alternatively, the identification information may be displayed not on the guide plate 17 but on each of the charging boxes 15a to 15d.

The identification information may be written as characters that are read by the user, for example. For example, the address notation of the place where the charging stand 10 is installed and the codes unique to the charging boxes 15a to 15d. For example, the mobile communication terminal that performs charging may be displayed as a two-dimensional barcode that can be read by a camera. In this case, the identification information is printed on, for example, a sticker and attached to the guide plate 17 or the like. Therefore, the guide plate 17 may be a simple board.
Alternatively, the guide plate 17 may be a display device that displays electronic information. In that case, since the display device is driven by an independent power source including the solar panel 12 and the storage battery 13, it is preferable to use a power-saving and self-holding device such as electronic paper.

Next, the configuration of the independent charging system of this embodiment including the charging stand 10 will be described.
FIG. 2 is a block diagram showing an example of the configuration of the stand-alone charging system and communication between devices including the charging station 10 according to this embodiment.

The stand-alone charging system includes a charging stand 10 and a charging management server 30. The mobile communication terminal 40 is an object to be charged and is not included in the stand-alone charging system.
The charging stand 10 includes a power feeding circuit 23, a communication circuit 24, and a charging control circuit 25 in addition to the power generation circuit 21 including the solar panel 12, the storage battery 13, and the LED lighting 16.
The power generation circuit 21 is a circuit that supplies and stores the power generated by the solar panel 12 to the storage battery 13 or supplies the power to the power supply circuit 23 for charging.
The power feeding circuit 23 is a circuit that outputs power to the user's mobile communication terminal 40 connected to the charging terminals 23T of the charging boxes 15a to 15d to perform charging.
In this embodiment, the mobile communication terminal 40 is charged via the charging terminal 23T. However, the present invention is not limited to this, and charging by a non-contact power feeding method may be used.

The charging control circuit 25 is a circuit that turns on and off the power supply from the power feeding circuit 23 to the mobile communication terminal 40 via the charging terminal 23T. In FIG. 2, the function is indicated by a switch of the power feeding circuit 23. The charge control circuit 25 operates the switch.
The charging control circuit 25 turns the power feeding of the power feeding circuit 23 on and off in accordance with an instruction sent from the charge management server 30 via the communication circuit 24. As a configuration for realizing the function, the charge control circuit 25 of this embodiment includes a microcomputer.

The communication circuit 24 acquires the state from the storage battery 13 and transmits it to the charge management server 30, and provides the instruction received from the charge management server 30 to the charge control circuit 25. The communication with the charge management server 30 is not limited to the wireless / wired form, and the communication method and the compliance standard are not limited. However, wireless communication is preferable to wired communication from the viewpoint of disaster response capability. For example, you may communicate with the charge management server 30 using the system similar to a mobile telephone. In addition, LPWA (Low Power Wide Area), which has low power consumption compared with a cellular phone system, can be selected.
Since the notification unit 26 is not an essential configuration, it is indicated by a chain line. In the description of FIG. 1, it is described that the guide plate 17 may be a display device. In this case, the display device corresponds to the notification unit 26. However, the display is not limited to sound, and sounds such as sound and buzzer may be used, and even a display device may be a display by turning on / off a lamp instead of a graphic display.

The notification unit 26 performs notification based on information received from the charge management server 30 via the communication circuit 24. For example, the storage battery 13 is informed of a non-chargeable state in which charging is not possible due to insufficient remaining capacity. When the user approaches the charging stand 10, the information notified by the notification unit 26 can be read or heard. Therefore, it can be recognized that charging is not possible before starting the operation related to charging.
Even when the notification unit 26 is not provided, the user can recognize the non-chargeable state based on information sent from the charge management server 30 to the mobile communication terminal 40.

The charge management server 30 includes a server processing unit 31, a server storage unit 32, and a server communication circuit 33.
The server processing unit 31 is configured around a CPU, and executes processing as the charge management server 30. The server storage unit 32 is a storage device that stores processing programs and data executed by the CPU.
The server communication circuit 33 is an interface circuit that communicates with the charging station 10 and the mobile communication terminal 40.
The charge management server 30 communicates with one or more charging stations 10 to perform management for permitting and prohibiting charging of each charging box.

≪Processing procedures related to charging≫
Then, the procedure of the process which charges a user's portable communication terminal 40 using the charging stand 10 is described.
FIG. 3A and FIG. 3B are flowcharts showing an example of processing executed when each device shown in FIG. 2 is charged and communication between devices.
The processing procedure will be described with reference to FIGS. 3A, 3B, and 2. FIG.

  As shown in FIG. 3A, in this embodiment, charging of the mobile communication terminal 40 starts from an operation in which a user sends a charge request to the charge management server 30 using the mobile communication terminal 40. At that time, the user performs an operation of inputting the identification information displayed on the guide plate 17 or the charging boxes 15a to 15d to the mobile communication terminal 40 (step S301). For example, the identification information is acquired by causing the camera of the mobile communication terminal 40 to read the two-dimensional barcode displayed on the guide plate 17 or the charging boxes 15a to 15d for that purpose.

The two-dimensional bar code includes an identification code unique to the charging stand and the charging box and information on a predetermined communication destination. When the portable communication terminal 40 confirms transmission to the user and obtains confirmation from the user, the portable communication terminal 40 transmits the identification code to the predetermined communication destination (step S303). Confirmation to the user is also confirmation that a charge request is transmitted.
The acquisition of identification information is not limited to manual input by a user or reading of a two-dimensional barcode using a camera. For example, the portable communication terminal 40 approaching the charging station 10 may be connected to the charging station 10 using a near field communication technique such as Near Field Communication, Bluetooth (registered trademark), or iBeacon (registered trademark). 10 may be configured to acquire information unique to the information.
When receiving the identification code from the portable communication terminal 40, the charge management server 30 determines that a request for charging has been received (Yes in step S201). Then, the remaining capacity of the storage battery 13 is inquired to the charging station 10 specified by the identification code (step S203).

The charging station 10 that has received the inquiry (step S101) returns the remaining capacity of the storage battery 13 (step S103).
In addition, although it demonstrates as what performs charge for a predetermined period (for example, 5 minutes) here, this is only an example and can apply various methods.
The charge management server 30 that has received the remaining capacity of the storage battery 13 predicts whether or not there is a remaining capacity sufficient to execute the charging of the mobile communication terminal 40 over the above-described predetermined period (step S205). ).

  If it is determined that there is not a sufficient remaining amount (No in Step S205), the charge management server 30 returns to the portable communication terminal 40 that has transmitted the charge request that charging is impossible (Step S207). Further, an instruction to prohibit charging is sent to the charging station 10 (step S211 in FIG. 3B), and the process ends.

The mobile communication terminal 40 that has received the notification that charging is not possible (step S305) displays on the screen, for example, that the battery cannot be charged due to insufficient remaining capacity, and notifies the user (step S307), and ends the process.
Further, the communication circuit 24 of the charging station 10 that has received the instruction to prohibit charging (step S105 in FIG. 3B) sends the instruction to the charging control circuit 25 so that the charging circuit 23 is not newly charged (step S105). S107), the process is terminated. When the charging station 10 includes the notification unit 26, the notification unit 26 is further instructed to notify that the charging is not possible (not illustrated in FIG. 3B).

On the other hand, when the charge management server 30 predicts that there is a sufficient remaining capacity in the storage battery 13 in Step S205 (Yes in Step S205 in FIG. 3A), the mobile communication terminal 40 is notified of the chargeable state (Step S209). Further, an identification code is added to the charging stand 10 and a charging permission instruction is sent (step S213 in FIG. 3B).
Receiving the notification of the chargeable state (step S309 in FIG. 3A), the mobile communication terminal 40 notifies the user that the charge terminal 23T is connected to the mobile communication terminal 40 so that it can be charged (step in FIG. 3B). S313).

In addition, the communication circuit 24 of the charging station 10 that has received the notification of charging permission (step S109 in FIG. 3B) sends the instruction to the charging control circuit 25. The charging control circuit 25 turns on the power feeding circuit 23 and starts charging the mobile communication terminal 40 connected to the charging terminal 23T (step S111).
The charge management server 30 sends a notification of the end of charging to the mobile communication terminal 40 (step S217) when a predetermined charging period has elapsed after sending a charge permission instruction in step S211 described above (step S215). Then, the routine proceeds to step S211 described above, sends an instruction to prohibit charging to the charging station 10, and ends the process.

  It should be noted that charging is not performed when the mobile communication terminal 40 is not started due to a failure of the storage battery 13 or the power supply circuit 23 even though the user has waited with the charging terminal 23T connected in response to the notification in the step S313. There may be provided means for the mobile communication terminal 40 to inform the charge management server 30 that the operation is unsuccessful. For example, at the same time as the process of step S313, a button is displayed on the screen of the mobile communication terminal 40 to notify that charging is unsuccessful, and when the user operates the button, the charging management server 30 is notified of charging failure. is there.

The charge management server 30 that has received the notification of unsuccessful charging determines that it is necessary to check the charging station 10 or the charging box related to the charging of the mobile communication terminal 40 that has sent the notification, A notification requesting inspection may be sent to the maintenance supervisor.
In addition, a notification that guides the location of another nearest charging station may be sent to the mobile communication terminal 40 to guide the user to the charging station.

Receiving the notification of the end of the charging period (step S319), for example, the mobile communication terminal 40 displays a charging end screen to notify the user (step S321), and ends the process.
Further, the charging station 10 that has received the instruction to prohibit charging in step S211 (step S105) stops the charging of the power feeding circuit 23 (step S107) and ends the process.
Summarizing the above procedure, as shown in FIG. 2, the charge management server 30 that has received a charge request from the mobile communication terminal 40 stores the remaining capacity that can be charged in the charging stand 10 in the storage battery 13. Get an answer by inquiring whether or not If charging is possible, a charging permission is sent to the charging stand 10 to start charging. When a predetermined charging period elapses, a charging prohibition instruction is sent to the charging stand, and charging is terminated.

  On the other hand, when there is no remaining capacity that can be charged in the storage battery 13, the charge management server 30 sends an instruction to prohibit charging to the charging stand 10 and does not start charging. Further, the mobile communication terminal 40 is notified of the state where charging is not possible, and the user is informed accordingly.

(Embodiment 2)
Next, a mode in which the charge management server 30 exchanges with an external service providing server and performs charging in association with the service provision will be described.
FIG. 4 is a block diagram illustrating a configuration example different from the stand-alone charging system illustrated in FIG. 2 and an example of communication between devices. 5A to 5C are flowcharts illustrating an example of processing in each device illustrated in FIG. 4 and communication between devices.

  In the block diagram of FIG. 4, elements similar to those in FIG. Description of elements similar to those in FIG. 2 is omitted. 4 differs from FIG. 2 in that a service providing server 50 exists. The service providing server 50 is not included in the configuration of the independent charging system of this embodiment, and is an external element. However, the charge management server 30 communicates with the service providing server 50. The mobile communication terminal 40 also communicates with the service providing server 50. The charge management server 30 and the mobile communication terminal 40 do not exchange directly.

With reference to FIG. 5A to FIG. 5C, a procedure of processing related to charging of each device shown in FIG.
5A to 5C, the same reference numerals are assigned to the same processes as those in FIGS. 3A to 3B. Therefore, only a simple description of the same processing will be given.
Similar to the first embodiment, the process related to charging is started when the mobile communication terminal 40 receives the input of the charging request and the identification information (steps S301 and S303). However, it differs from the first embodiment in that the charging request and identification information are transmitted to the service providing server 50 instead of the charging management server 30.

When the charging request and the identification code for specifying the charging station 10 and the charging box are received from the portable communication terminal 40 (step S401), the service providing 50 server adds the identification code and inquires the remaining charge of the storage battery 13 to the charging management server 30. (Step S403).
Receiving the inquiry (step S201), the charge management server 30 inquires and sends the remaining capacity of the storage battery 13 to the charging station 10 specified by the identification code (step S203).
The charging station 10 that has received the inquiry returns the remaining capacity of the storage battery 13 to the charging management server 30 as in the first embodiment (steps S101 and S103).

The charge management server 30 that has received the response of the remaining capacity (step S221) sends the remaining capacity to the service providing server 50 (step 223).
The service providing server 50 that has received the response of the remaining capacity (step S405) determines whether the remaining capacity is chargeable (step S407).
The service providing server 50 makes this determination because, as will be described later, the service is provided to the user's mobile communication terminal 40 if charging is possible, and the service is not provided if charging is not possible. That is, whether or not charging is possible and service provision are closely related. However, as in the first embodiment, the charge management server 30 may make this determination. This is because the determination result is sent to the service providing server 50, and the service providing server 50 can perform processing based on the result.

The description will be continued along the flowchart.
If it is determined that there is not enough remaining (No in step S407 in FIG. 5B), the service providing server 50 notifies the mobile communication terminal 40 that charging is not possible (step S409). Furthermore, an instruction to stop charging is sent to the charge management server 30 (step S411), and the process ends.

The mobile communication terminal 40 that has received the notification that charging is not possible (step S305) informs the user that charging is not possible because the remaining capacity is not sufficient (step S307), and the processing ends, as in the first embodiment. .
The charge management server 30 that has received the instruction to stop charging (step S225 in FIG. 5B) sends an instruction to prohibit charging to the charging station 10 (step S227), and ends the process.
The charging station 10 that has received the instruction to prohibit charging (step S105 in FIG. 5B) does not perform new charging (step S107), and ends the process.

On the other hand, when the service providing server 50 determines that there is a sufficient remaining capacity in the storage battery 13 in Step S407 (Yes in Step S407), a pre-process related to service provision is executed for the mobile communication terminal 40 (Step S407). S413).
Here, as an example of pre-processing related to service provision, charging processing for a charging service to be performed from now on can be cited. In addition, a charging service is provided free of charge, but if it is a business model that browses advertisements for a certain period of time, an essential advertisement browsing process can be considered. In these processes, the service providing server 50 and the mobile communication terminal 40 communicate with each other, and when the user operates the mobile communication terminal 40, the process proceeds to a stage for starting charging.
When the pre-processing is completed and charging is started (step S311), the mobile communication terminal 40 connects the charging terminal 23T and displays it on the screen so that it can be charged. Notification is made (step S313).

When the pre-processing related to service provision ends, the service provision server 50 sends a charge start instruction to the charge management server 30 (step S415).
Receiving the instruction to start charging (step S229), the charge management server 30 sends a charge permission instruction to the charging station 10 (step S231 in FIG. 5C).

The charging station 10 that has received the notification of charging permission (step S109 in FIG. 5C) starts charging the mobile communication terminal 40 connected to the charging terminal 23T (step S111). Then, a charge start notification is sent to the charge management server 30 (step S113).
The charge management server 30 that has received the charge start notification sends a charge start notification to the service providing server 50 (step S235).

The service providing server 50 that has received the notification of the start of charging (step S417 in FIG. 5C) starts providing the service to the mobile communication terminal 40 (step S419) when further providing the service during charging. For example, it is a service such as displaying an advertisement during the charging period of the mobile communication terminal 40 (step S315 in FIG. 5C).
If an advertisement is displayed on the mobile communication terminal 40 that is being charged, the power of the mobile communication terminal 40 is used to display the advertisement, and the user may feel dissatisfied. Therefore, when the charging station 10 includes a display device as the notification unit 26, an instruction may be sent via the charge management server 30 to display an advertisement on the display device of the notification unit 26.

Furthermore, when the mobile communication terminal 40 provides position information, the service providing server 50 acquires the current position of the mobile communication terminal 40 and displays an advertisement on the notification unit 26 as long as it matches the position where the charging station 10 is installed. You may make it make it. That is, when the mobile communication terminal 40 moves away from the installation position of the charging station 10, the advertisement display may be stopped so that the charging station 10 does not waste power.
When it is determined that it is time to end the provision of the charging service and the charging after the predetermined charging period has elapsed (step S421), the service providing server 50 sends an instruction to stop charging to the charging management server 30 (step S423). ). Furthermore, a service end notification is sent to the mobile communication terminal 40 (step S425). Then, the process ends.

The charge management server 30 that has received the instruction to stop charging (step S225 in FIG. 5B) sends an instruction to prohibit charging to the charging station 10 (step S227), and ends the process.
The charging station 10 that has received the instruction to prohibit charging (step S105 in FIG. 5B) does not perform new charging (step S107), and ends the process.
Also, the mobile communication terminal 40 that has received the service end notification (step S317 in FIG. 5C) notifies the user of the end of charging (step S321), and ends the process.
Since the independent charging devices of the first and second embodiments include a charging control circuit that permits and prohibits the charging based on instructions for charging permission and charging prohibition from an external charge management server, charging is performed as one service. Can be provided. That is, charging is permitted and prohibited based on an instruction from an external charge management server. For example, a service can be provided by receiving instructions for charging permission and charging prohibition in association with the service. The same can be said for the independent charging systems of the first and second embodiments.

(Embodiment 3)
In the first and second embodiments, the mode in which the mobile communication terminal 40 is charged in a predetermined period during normal use has been described. However, in the event of an emergency such as a disaster, when the charge management server 30 receives a notification of the occurrence of an emergency from an external device, the charge management server 30 notifies the occurrence of the emergency to one or more charging stations 10. To do.

The communication circuit of the charging station 10 that has received the notification of the occurrence of an emergency situation sends the notification to the charging control circuit 25. In response to the notification, the charging control circuit 25 keeps the power feeding circuit 23 turned on so that anyone can freely charge.
Alternatively, the charge management server 30 may transmit a charge permission instruction for the charge box instead of the above-described notification of occurrence of an emergency. Anyone can freely charge unless a charge prohibition instruction is sent.
When an emergency occurs, in order to secure more power for charging, for example, the brightness of the LED illumination 16 may be lowered than that during normal use.
The independent charging device according to Embodiment 3 can cope with emergencies such as disasters. As in the first and second embodiments, if a charge control circuit for permitting and prohibiting the charge is provided based on a charge permission and charge prohibition instruction from an external charge management server, charging is normally performed as one service. And can respond to emergencies such as disasters. That is, charging is permitted and prohibited based on an instruction from an external charge management server. For example, by receiving a charge permission and charge prohibition instruction in association with a service during normal times, and receiving a charge permission instruction when an emergency occurs, both service provision and emergency response can be achieved.
The same can be said for the independent charging system according to the third embodiment.

(Embodiment 4)
Various aspects of managing the charging period will be described.
In Embodiments 1 and 2, a mode has been described in which charging is stopped when a predetermined period has elapsed from the start of charging.
For example, in the stand-alone charging system of the first embodiment, when the user releases the connection of the charging terminal 23T and takes away the mobile communication terminal 40 before the charging period ends, the charging station 10 detects the presence or absence of the connection. If you do not have the means to do it, you cannot recognize it.
However, the user who wants to charge using the charging box next sends a charge request to which the identification information is added to the charge management server 30.

At that time, the charge management server 30 receives a charge request related to the charge box that should be charging.
In that case, for example, a new charging request may be rejected until the charging period elapses. In this way, even if the user sends a charge request with incorrect identification information added, the management will not be confused.
Alternatively, when the charge management server 30 receives a charge request related to a charge box that should be charging, the charge management server 30 may consider that the previous charge has ended and start a new charge. In this case, even if the user removes the charging terminal 23T and stops charging before the charging period elapses, the next user can start a new charging without any problem.

Alternatively, the charging control circuit 25 detects whether or not the charging terminal 23T is connected to the portable communication terminal 40, and stops charging when the connection is released, and the charge management server 30 via the communication circuit 24. May inform the end of charging.
In particular, in the system in which the service providing server 50 exists as in the second embodiment and the metering charge is made for the charging service, the charging can be terminated by detecting the disconnection of the charging terminal 23T.
However, even for pay-per-use, detecting the connection of the charging terminal 23T is not an essential configuration. When the user operates the mobile communication terminal 40 to send a charge termination request to the service providing server 50, the charging may be stopped together with the charging.
