[Diagram 2] FIG. 2 is a block diagram showing the details of each component of the power supply system according to the embodiment. [Diagram 3] FIG. 3 is a flowchart illustrating an example of a processing procedure of a power supplying method executed by the power supply device according to the embodiment. 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 Fig. 1 and Fig. 2. The power supply system 1 includes a power supply device 10 and a travel support device 20, as shown in Fig. 1.

[0011] The power supply device 10 and the mobility support device 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 mobility support device 20 such as an elevator or an escalator. 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 mobility support device 20.

[0013] 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.

[0014] 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 device specifying unit 111 and a power supply unit 112 through the execution of the program stored in the memory unit 13.

[0015] The device identification unit 111 identifies the mobility support device 20 used by a preset user (person requiring assistance). The term "person requiring assistance" refers to a person who is suddenly ill or a user who uses a wheelchair, a cane, or the like, and is expected to evacuate using the mobility support device 20 in the event of a disaster. Examples of "disasters" include earthquakes, volcanic disasters, floods (heavy rain), landslides, heavy snowfall, and typhoons.

[0016] The device identification unit 111, for example, identifies an elevator in a building (for example, an apartment building) in which the person requiring support lives, and stores information about the identified elevator in the storage unit 13. If there are multiple elevators in the building, the device identification unit 111 may identify an elevator that is frequently used by the person requiring support.

[0017] Furthermore, the device identification unit 111 identifies an elevator in a facility (e.g., a care facility) used by the person requiring support, and stores information about the identified elevator in the storage unit 13. If there are multiple elevators in the facility, the device identification unit 111 may identify an elevator that is frequently used by the person requiring support.

[0018] The method of identifying the mobility support device 20 in the device identification unit 111 is not particularly limited, and for example, the device may be identified based on information obtained from a server or the like installed in the building in which the person in need of support lives or in a facility used by the person in need of support, or the device may be identified based on information obtained from a terminal or the like owned by the person in need of support or their family.

[0019] The power supply unit 112 supplies power to the mobility support device 20, for example, based on a power supply request from the mobility support device 20. When a disaster occurs, the power supply unit 112 prioritizes the supply of power to the mobility support device 20 used by the person requiring support identified by the device identification unit 111 over the supply of power to the mobility support device 20 not used by the person requiring support. In this case, the power supply unit 112 supplies power only to the mobility support device 20 used by the person requiring support, or supplies more power to the mobility support device 20 used by the person requiring support than to the mobility support device 20 not used by the person requiring support.

[0020] In this way, when a disaster occurs, by supplying power preferentially to mobility support devices 20 such as elevators used by people in need of assistance who use daily life support devices, the people in need of assistance can use these mobility support devices 20 to evacuate, thereby preventing people in need of assistance from being late in escaping.

[0021] 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 mobility support device 20 by connecting to the network NW.

[0022] 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).

[0023] The storage unit 13 can store an operating system (OS), various programs, various tables, various databases, etc. The storage unit 13 stores, as necessary, information about the travel support device 20 identified by the device identification unit 111, for example.

[0024] (Mobility support device) The mobility support device 20 is a device for supporting the mobility of a user. Examples of the mobility support device 20 include an elevator, an escalator, a moving walkway (horizontal escalator), and the like. In this embodiment, the mobility support device 20 will be described assuming that it is an elevator. In addition, the mobility support device 20 and the power supply device 10 are connected by a power supply network, and are configured to be supplied with power from the power supply device 10.

[0025] (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.

[0026] First, the device identification unit 111 identifies the mobility support device 20 used by the person requiring support (step S1). Next, the power supply unit 112 determines whether or not a disaster has occurred (step S2). In step S2, a positive determination 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 determination is made when information about a specific disaster is not acquired.

[0027] If it is determined in step S2 that a disaster has occurred (Yes in step S2), the power supply unit 112 prioritizes the supply of power to the mobility support device 20 used by the person requiring support over the supply of power to the mobility support device 20 not used by the person requiring support (step S3), and ends this flow. Note that if it is determined in step S2 that a disaster has not occurred (No in step S2), the power supply unit 112 returns to the determination in step S2.

[0028] As described above, in the power supply device according to the embodiment, when a disaster occurs, power supply to the mobility support device 20 used by the person requiring support is prioritized over power supply to the mobility support device 20 not used by the person requiring support. This allows the person requiring support to evacuate using the mobility support device 20 when a disaster occurs, thereby preventing the person requiring support from being late in escaping.

[0029] 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.

[0030] For example, the power supply device 10 may constantly keep track of the actions of the person requiring support by utilizing the GPS function of a terminal owned by the person requiring support and the GPS function of a wheelchair or electric walking stick that can communicate with the outside and is used by the person requiring support, and may supply power to the mobility support device 20 at each destination the person requiring support goes to in accordance with the movement of the person requiring support. In this case, if the power supply device 10 is configured with charging mobility (e.g., an electric vehicle), power may be supplied from the power supply device 10 to the mobility support device 20 that is expected to be used by the person requiring support in accordance with the movement of the person requiring support.
