DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A power supply device according to an embodiment of the present disclosure will be described with reference to the drawings. Note that components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0010] (Power supply system) A power supply system including a power supply device according to an embodiment will be described with reference to Figures 1 and 2. The power supply system 1 includes a power supply device 10 and a terminal 20, as shown in Figure 1.

[0011] The power supply device 10 and the terminal 20 each have a communication function and are configured to be able to communicate with each other via a network NW. This network NW is configured, for example, from the Internet, a mobile phone network, or the like.

[0012] (Power supply device) The power supply device 10 is for supplying power to a terminal 20 owned by a user. The power supply device 10 is realized by, for example, a general-purpose computer such as a workstation or a personal computer, a charging mobility (for example, an electric vehicle), etc. The power supply device 10 also has a power supply function for supplying power to the terminal 20.

[0013] In this embodiment, a "user" refers to a person who owns the terminal 20. This user includes a first user and a second user other than the first user. The first user is assumed to be an elderly person, a physically and mentally disabled person, an injured person, or the like who uses a daily living support device (e.g., a wheelchair, a cane, or the like), and is assumed to be a person who has difficulty or is unable to evacuate on his / her own when a disaster occurs. The second user is assumed to be a healthy person other than the first user, and is assumed to be a person who can easily evacuate on his / her own when a disaster occurs. In addition, examples of "disasters" include earthquakes, volcanic disasters, floods (heavy rain), landslides, heavy snowfall, typhoons, and the like.

[0014] 2, the power supply device 10 includes a control unit 11, a communication unit 12, and a storage unit 13. Specifically, the control unit 11 includes a processor including a central processing unit (CPU), a digital signal processor (DSP), a field-programmable gate array (FPGA), a graphics processing unit (GPU), etc., and a memory (main storage unit) including a random access memory (RAM), a read only memory (ROM), etc.

[0015] The control unit 11 loads a program stored in the memory unit 13 into a working area of ​​the main memory unit, executes the program, and realizes a function that meets a predetermined purpose by controlling each component unit through the execution of the program. The control unit 11 functions as a priority setting unit 111 and a power supply unit 112 through the execution of the program stored in the memory unit 13.

[0016] The priority setting unit 111 sets the priority of power supply to the terminal 20. The priority setting unit 111 acquires terminal registration information, for example, from the terminal 20 via the network NW. This "terminal registration information" is information for requesting registration of the terminal 20 that receives power supply from the power supply device 10. The terminal registration information includes information that can identify the terminal 20 (for example, an identification ID, etc.), information on whether the user who uses the terminal 20 uses a daily life support device, information on the type of daily life support device, etc.

[0017] The terminal registration information may be acquired from a terminal 20 of a user other than the user who owns the terminal 20. For example, if the user who owns the terminal 20 is an elderly person, the terminal registration information of the terminal 20 of the user (elderly person) may be acquired from a terminal 20 owned by a family member of the user.

[0018] The priority setting unit 111 sets different priorities for the power supply to each terminal 20 when a disaster has occurred and when a disaster has occurred. For example, when a disaster has not occurred, the priority setting unit 111 does not particularly set a priority for the power supply to each terminal 20, or sets the priority so that power is supplied on a first-come, first-served basis.

[0019] On the other hand, when a disaster occurs, the priority setting unit 111 sets the priority of power supply to the terminal 20 owned by a preset user higher than the priority of power supply to the terminal 20 owned by a user other than the preset user. The "preset user" refers to a user (hereinafter also referred to as a "first user") who uses a daily life support device (e.g., a wheelchair, a cane, etc.). The "user other than the preset user" refers to a user (hereinafter also referred to as a "second user") who does not use the daily life support device. The priority setting unit 111 obtains information on whether or not a disaster has occurred from, for example, a server of an organization or company that provides disaster information.

[0020] The priority setting unit 111 may set the priority of power supply on a region basis, in addition to setting the priority of power supply on a terminal 20 basis as described above. In this case, when a disaster occurs, the priority setting unit 111 sets the priority of power supply in the region where the first user resides higher than the priority of power supply in the other regions where the second users reside. In other words, power is supplied only to the region where the first user resides, and power is not supplied to the other regions where the second users reside.

[0021] Furthermore, the priority setting unit 111 may set more detailed priorities among the terminals 20 owned by the first user. For example, the priority setting unit 111 may set the priority of power supply to the terminals 20 owned by the first users who cannot move without the daily life support device (cannot move by themselves) higher than the priority of power supply to the terminals 20 owned by the users who can move without the daily life support device.

[0022] The power supply unit 112 supplies power to the terminal 20 based on, for example, a power supply request from the terminal 20. The power supply unit 112 supplies power to the terminal 20 based on the priority set in the priority setting unit 111. For example, if a disaster occurs and the priority setting unit 111 sets the priority of power supply to the terminal 20 of a first user higher than the priority of power supply to the terminal 20 of a second user, the power supply unit 112 does not supply power to the terminal 20 of the second user, but supplies power only to the terminal 20 of the first user.

[0023] In this way, when a disaster occurs, power is supplied preferentially to the terminal 20 of the user (first user) who uses the daily life support device, making it possible to contact the user and reliably provide rescue to the user and confirm his or her safety.

[0024] The communication unit 12 is composed of, for example, a LAN (Local Area Network) interface board, a wireless communication circuit for wireless communication, etc. The communication unit 12 is connected to a network NW such as the Internet, which is a public communication network. The communication unit 12 communicates with the terminal 20 by connecting to the network NW.

[0025] The storage unit 13 is composed of recording media such as an EPROM (Erasable Programmable ROM), a hard disk drive (HDD), and removable media. Examples of removable media include disk recording media such as a Universal Serial Bus (USB) memory, a Compact Disc (CD), a Digital Versatile Disc (DVD), and a Blu-ray (registered trademark) Disc (BD).

[0026] The storage unit 13 can store an operating system (OS), various programs, various tables, various databases, etc. The storage unit 13 stores, as necessary, terminal registration information of each terminal 20 acquired via the network NW, information on the priority of power supply to each terminal 20 set in the priority setting unit 111, etc.

[0027] (Terminal) The terminal 20 is a terminal device capable of communicating with the outside world, and is owned by a user. The terminal 20 is realized by, for example, a smartphone, a mobile phone, a tablet terminal, a wearable computer, a general-purpose computer such as a workstation or a personal computer, etc. Note that the terminal 20 may be a portable device or a non-portable device (for example, a desktop personal computer) as long as it is capable of communicating with the outside world.

[0028] 2, the terminal 20 includes a control unit 21, a communication unit 22, a storage unit 23, and an operation / display unit 24. The control unit 21, the communication unit 22, and the storage unit 23 are similar in terms of hardware to the control unit 11, the communication unit 12, and the storage unit 13.

[0029] The communication unit 22 communicates with the power supply device 10 by wireless communication via the network NW. The storage unit 23 stores, for example, terminal registration information and the like as necessary.

[0030] The operation / display unit 24 is configured with, for example, a touch panel display, and has an input function for accepting operations by the user's finger, pen, etc., and a display function for displaying various information based on the control of the control unit 21. The operation / display unit 24 displays, for example, a transmission screen for terminal registration information, etc., based on the control of the control unit 21.

[0031] (Power supply method) An example of the procedure of the power supply method executed by the power supply device 10 according to the embodiment will be described with reference to FIG.

[0032] First, the power supply unit 112 judges whether or not a disaster has occurred (step S1). In step S1, a positive judgment is made when information about a disaster is acquired from, for example, a server of an organization or company that provides disaster information, and a negative judgment is made when information about a specific disaster is not acquired.

[0033] In step S1, when it is determined that a disaster has occurred (Yes in step S1), the power supply unit 112 causes the priority setting unit 111 to set the priority of power supply to the terminal 20 owned by the first user higher than the priority of power supply to the terminal 20 owned by the second user (step S2). Note that in step S1, when it is determined that a specific disaster has not occurred (No in step S1), the priority setting unit 111 returns to the determination in step S1.

[0034] Next, the power supply unit 112 supplies power to the terminal 20 based on the priority order set in step S2 (step S3), and ends this flow.

[0035] As described above, in the power supply device according to the embodiment, when a disaster occurs, the priority of power supply to the terminal 20 owned by a user (first user) who uses a daily life assistance device is set higher than the priority of power supply to the terminal 20 owned by a user (second user) who does not use the daily life assistance device. This makes it possible to preferentially supply power to the terminal 20 owned by a user who uses a daily life assistance device that is not an electrically-powered medical device when a disaster occurs.

[0036] Therefore, even if the battery level of the terminal 20 of a user using the daily life support device becomes low when a disaster occurs, the terminal 20 can be charged and contact can be made with the outside world, so that rescue of the user using the daily life support device and confirmation of the user's safety can be reliably carried out.

[0037] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Thus, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
