[Second Embodiment]
Next, a second embodiment of the present disclosure will be described with reference to FIGS. FIG. 2 is a block diagram of the power supply device 2 according to the present embodiment. As illustrated in FIG. 2, the power supply device 2 includes a first USB interface unit 21, a second USB interface unit 22, a power supply unit 23, a detection unit 24, a notification unit 25, and a storage unit 26.
The first USB interface unit 21, the second USB interface unit 22, the power feeding unit 23, the detection unit 24, the notification unit 25, and the storage unit 26 are electrically connected to each other.

In the present embodiment, the power supply device 2 is used by being connected to the router 3 and the wireless communication terminal 4.
The router 3 is a router used for, for example, a commercial wireless or wired network line, and relays communication of a network device or the like. The router 3 has a USB port 31 and a power supply unit 32.
The wireless communication terminal 4 uses a wireless line of a communication standard such as 3G (3rd generation), 4G (4th generation), and LTE (Long Term Evolution) based on the acquired power supply and electric signal without using the router 3. It is a terminal that can perform wireless communication. The wireless communication terminal 4 includes a USB connector 41 and a communication unit 42.

The first USB interface unit 21 is a USB connector connected to the USB port 31 of the router 3. The first USB interface unit 21 performs data communication conforming to USB standards such as USB 2.0, USB 3.0, USB 3.1, USB 3.2, and the like. Note that data communication conforming to the USB standard is the same as a known method, and thus detailed description thereof is omitted.
The power supply device 2 can exchange electrical signals with the router 3 via the first USB interface unit 21. The power supply device 2 can also obtain power from the router 3 in accordance with the USB standard via the first USB interface unit 21.

The second USB interface unit 22 is a USB port connected to the USB connector 41 of the wireless communication terminal 4. The second USB interface unit 22 performs data communication conforming to the USB standard.
The power supply device 2 can exchange electrical signals with the wireless communication terminal 4 via the second USB interface unit 22. Further, the power supply device 2 can also supply power to the wireless communication terminal 4 through the second USB interface unit 22 in accordance with the USB standard.

  The power supply unit 23 includes an electronic component that can store electricity, such as a capacitor or a secondary battery. The power supply unit 23 can store power from the router 3 via the first USB interface unit 21. The power supply unit 23 can supply power stored in a capacitor, a secondary battery, or the like to the wireless communication terminal 4 via the second USB interface unit 22.

The detection unit 24 detects a power supply abnormality of the router 3. For example, when the power supply from the router 3 to the power supply device 2 is interrupted, the detection unit 24 determines that a power supply abnormality has occurred in the router 3. Alternatively, the detection unit 24 may monitor an electrical signal received from the router 3 and may determine that a power supply abnormality has occurred in the router 3 when the electrical signal is interrupted.
The detection unit 24 outputs a detection signal when a power supply abnormality of the router 3 is detected. The detection signal is a signal notifying that the detection unit 24 has detected a power supply abnormality of the router 3. Note that the detection unit 24 may include information on the time when the power supply abnormality of the router 3 is detected in the detection signal.

The notification unit 25 outputs a notification signal when the detection signal is acquired. The notification signal is a signal for notifying the power supply abnormality of the router 3 and is output to the wireless communication terminal 4 via the second USB interface unit 22.
Note that the notification unit 25 may include information on the time when the detection unit 24 detects the power supply abnormality of the router 3 in the notification signal based on the acquired detection signal. Further, the notification unit 25 may include information stored in the storage unit 26 described later in the notification signal.

  The storage unit 26 is a device that can store information such as electrical signals acquired from the router 3 and the wireless communication terminal 4. The storage unit 26 may store information such as a detection signal acquired from the detection unit 24 and a notification signal acquired from the notification unit 25. For the storage unit 26, for example, a storage medium such as a volatile memory or a nonvolatile memory is used.

The USB port 31 is a USB port that can be connected to the first USB interface unit 21 of the power supply device 2. In addition to supplying power to the power supply device 2 via the USB port 31, the router 3 can exchange electrical signals with the power supply device 2.
The power supply unit 32 is connected to a commercial power source and acquires commercial power as a power source for the router 3. The commercial power is, for example, AC power having a voltage of 100 V or 200 V and a frequency of 50 Hz or 60 Hz. The power supply unit 32 includes, for example, a power plug connected to an outlet that outputs commercial power.

The USB connector 41 is a USB connector that can be connected to the second USB interface unit 22 of the power supply device 2. The wireless communication terminal 4 can receive electric power from the power supply device 2 via the USB connector 41 and can exchange electric signals with the power supply device 2.
The communication unit 42 performs wireless communication based on the acquired electrical signal.

Here, the operation of the power supply device 2 will be described with reference to FIGS. 3 and 4. FIG. 3 is a schematic diagram illustrating a state of the power supply device 2 when no power supply abnormality has occurred in the router 3. FIG. 4 is a schematic diagram illustrating a state of the power supply device 2 when a power supply abnormality has occurred in the router 3.
The management terminal 5 shown in FIGS. 3 and 4 is a communication terminal managed by a user.

  When no power supply abnormality has occurred in the router 3, the wireless communication terminal 4 acquires power from the router 3 via the power supply device 2. That is, the wireless communication terminal 4 acquires power via the power supply unit 32, the USB port 31, the first USB interface unit 21, the second USB interface unit 22, and the USB connector 41, as indicated by the thick arrows in FIG. . Therefore, the wireless communication terminal 4 can perform wireless communication with the management terminal 5 via the communication unit 42 without using the power stored in the power supply unit 23 by using the power supplied from the router 3. .

  In addition, the router 3 and the wireless communication terminal 4 can exchange electric signals bidirectionally via the power supply device 2. Furthermore, the wireless communication terminal 4 and the management terminal 5 can also exchange electrical signals in both directions via wireless communication. Therefore, even when the management terminal 5 is arranged at a location away from the router 3, the management terminal 5 can exchange electrical signals with the router 3 in both directions.

  On the other hand, when a power failure occurs in the router 3 due to a power failure or the like, power cannot be supplied from the power supply unit 32 to the power supply device 2 as indicated by a cross in FIG. In this case, the power supply unit 23 of the power supply device 2 supplies the stored power to the wireless communication terminal 4 via the second USB interface unit 22. Therefore, the wireless communication terminal 4 can perform wireless communication with the management terminal 5 via the communication unit 42 by using the power stored in the power supply unit 23.

  In addition, the notification unit 25 outputs a notification signal to the wireless communication terminal 4 using the power stored in the power supply unit 23. The wireless communication terminal 4 transmits the acquired notification signal to the management terminal 5. Since the notification signal is a signal notifying the power supply abnormality of the router 3, the management terminal 5 can detect the power supply abnormality of the router 3 by acquiring the notification signal. In this way, the notification unit 25 can notify the power failure of the router 3 via the wireless communication terminal 4.

  Further, when the notification signal includes information on the time when the detection unit 24 detects the power supply abnormality of the router 3, the management terminal 5 can acquire the time when the power supply abnormality occurred in the router 3. In this way, the notification unit 25 can notify the time when the detection unit 24 detects the power supply abnormality of the router 3.

When the information stored in the storage unit 26 is included in the notification signal, the management terminal 5 can acquire the information stored in the storage unit 26. In this way, the notification unit 25 can notify the management terminal 5 of the information stored in the storage unit 26.
In this case, the management terminal 5 can acquire information related to the operations of the power supply device 2, the router 3, and the wireless communication terminal 4 before the power failure occurs in the router 3. Therefore, the information can be used for investigating the cause of power supply abnormality.

  Next, the processing flow of the power supply device 2 will be described with reference to FIG. FIG. 5 is a flowchart showing a processing flow of the power supply device 2 connected to the router 3 and the wireless communication terminal 4. When the power supply device 2 detects the power supply from the router 3, the power supply device 2 starts the process of step S10 shown in FIG.

  First, in step S <b> 10, the detection unit 24 of the power supply device 2 determines whether or not the router 3 has a power supply abnormality. If the detection unit 24 has not detected a power supply abnormality of the router 3 (NO in step S10), the process proceeds to step S20. If the detection unit 24 has detected a power supply abnormality of the router 3 (YES in step S10), the process proceeds to step S40. move on.

  When the process proceeds to step S20, if the power supply unit 23 can store power (YES in step S20), the process proceeds to step S25. If the power supply unit 23 is fully charged and cannot store any more power (NO in step S20), the process proceeds to step S30.

  When the process proceeds to step S <b> 25, the power supply unit 23 stores a part of the power source acquired from the router 3. Thereafter, the process proceeds to step S30.

  When the process proceeds to step S <b> 30, the power supply device 2 supplies the wireless communication terminal 4 with the power acquired from the router 3. Further, when the power supply device 2 acquires an electrical signal from the router 3, the power supply device 2 transmits the electrical signal to the wireless communication terminal 4. When the wireless communication terminal 4 acquires an electrical signal from the router 3 via the power supply device 2, the wireless communication terminal 4 performs wireless communication with the management terminal 5 based on the electrical signal. Then, it returns to step S10 and continues a series of processes.

  On the other hand, when the process proceeds from step S <b> 10 to step S <b> 40, the power supply unit 23 supplies the stored power to the wireless communication terminal 4 via the second USB interface unit 22. The wireless communication terminal 4 can operate using the power stored in the power feeding unit 23. Thereafter, the process proceeds to step S50.

  In step S <b> 50, the notification unit 25 outputs a notification signal to the wireless communication terminal 4 via the second USB interface unit 22 using the power stored in the power supply unit 23. The wireless communication terminal 4 transmits the acquired notification signal to the management terminal 5. Then, it returns to step S10 and continues a series of processes.

  As described above, the power supply device 2 supplies power from the router 3 to the wireless communication terminal 4 when no power failure has occurred in the router 3. In addition, when a power supply abnormality has occurred in the router 3, the power supply device 2 supplies the stored power to the wireless communication terminal 4 and outputs a notification signal. By doing so, the power supply device 2 can notify the power failure of the router 3 via the wireless communication terminal 4.

  In the above example, the power supply device 2 has been described with reference to the configuration in which the process of step S10 is started when the power supply from the router 3 is detected. However, the power supply device 2 detects the connection with the router 3. Alternatively, the process of step S10 may be started. Alternatively, the power supply device 2 may start the process of step S10 when the connection with the wireless communication terminal 4 is detected.

  Moreover, although the structure which returns to step S10 after the radio | wireless communication terminal 4 transmitted the notification signal to the management terminal 5 at step S50 was demonstrated, a series of processes are performed after the radio communication terminal 4 transmits the notification signal to the management terminal 5. You may end. Alternatively, after the wireless communication terminal 4 transmits a notification signal to the management terminal 5, a series of processing may be terminated when the power stored in the power supply unit 23 becomes a certain value or less. By taking such a configuration, power consumption of the power supply device 2 can be suppressed.

[Third Embodiment]
Next, a third embodiment of the present disclosure will be described with reference to FIG. FIG. 6 is a block diagram of the power supply device 6 according to the present embodiment.

  The power supply device 6 in the third embodiment has the same configuration as that of the power supply device 1 in the first embodiment, except that a plurality of second USB interface units 62_1, ..., 62_n, and a determination unit 67 are provided. That is, the first USB interface unit 61, the power supply unit 63, the detection unit 64, and the notification unit 65 correspond to the first USB interface unit 11, the power supply unit 13, the detection unit 14, and the notification unit 15 in the first embodiment. The same processing is performed.

  The determination unit 67 determines whether or not wireless communication terminals (not shown in FIG. 6) connected to the plurality of second USB interface units 62_1,. For example, the determination unit 67 determines whether each wireless communication terminal can communicate by analyzing the communication history.

  The notification unit 65 notifies the wireless communication terminal that the determination unit 67 determines that communication is possible when the detection unit 64 detects a power supply abnormality of the router, to notify the power supply abnormality. In such a configuration, since wireless communication can be performed using a plurality of wireless communication terminals, wireless communication lines can be made redundant.

  Note that the notification unit 65 may not notify the wireless communication terminal that the determination unit 67 has determined that communication is impossible to notify the power supply abnormality. In such a configuration, since the power supply device 6 does not output a notification signal to a wireless communication terminal that cannot communicate, unnecessary power consumption can be suppressed.

  Note that the present disclosure is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present disclosure.
