[0012] A power supply system, a power supply method, and a program to which the present invention is applied will be described below with reference to the drawings.

[0013] FIG. 1 is a block diagram showing an example of the configuration of a power supply system 1 according to an embodiment. The power supply system 1 of the embodiment is an information processing system that supplies power to information processing devices (terminal devices) such as smartphones carried by evacuees at a shelter during a disaster, and provides evacuee information and safety information to an external device. While the following description focuses on evacuees during a disaster, the power supply system 1 of the embodiment may also be used to supply power to terminal devices carried by users gathered at a specific location, and to provide user information and information indicating the safety and status of the users to an external device.

[0014] The power supply system 1 includes, for example, a wireless power supply management device 100, a local government terminal device 110, a storage unit 120, a power transmission device 130, a temporary base station 140, a safety confirmation system 200, a destination device 210, and an evacuee terminal device 300. The wireless power supply management device 100, the local government terminal device 110, the storage unit 120, the power transmission device 130, the temporary base station 140, the safety confirmation system 200, the destination device 210, and the evacuee terminal device 300 are communicatively connected via a communication network such as the Internet. The communication network may be either wired or wireless, and may include a general-purpose network such as the Internet, or a private network such as local 5G or Wi-Fi (registered trademark). The wireless power supply management device 100, the local government terminal device 110, the memory unit 120, the power transmission device 130, the temporary base station 140, the safety confirmation system 200, the linked device 210, and the evacuee terminal device 300 may have a communication interface such as a NIC (Network Interface Card) or a wireless communication module for connecting to a network, and may exchange information with each other.

[0015] The evacuee terminal device 300 is an information processing device owned by an evacuee who has evacuated to an evacuation shelter. The evacuee terminal device 300 includes, for example, a transmission / reception unit 302, an application processing unit 304, a charging circuit 306, and a battery 308. The transmission / reception unit 302 includes a communication circuit for communicating with the wireless power supply management device 100 and a communication circuit for communicating with the power transmitting device 130. The application processing unit 304 is a processing circuit such as a CPU (Central Processing Unit) that executes application software for evacuee installed in the evacuee terminal device 300. The charging circuit 306 generates power based on a wireless signal from the power transmitting device 130 and charges the battery 308 with the power.

[0016] The wireless power supply management device 100 is a server device that receives requests from, for example, the evacuee terminal device 300, the local government terminal device 110, the power transmission device 130, the safety confirmation system 200, etc., and performs various processes. The wireless power supply management device 100 is installed, for example, in an evacuation shelter managed by a local government.

[0017] The local government terminal device 110 includes, for example, a registration unit 102, an acquisition unit 104, a power supply unit 106, and a transmission unit 108. The registration unit 102, the acquisition unit 104, the power supply unit 106, and the transmission unit 108 are functional units realized by an information processing circuit that performs various processes by causing a CPU to execute a program. Furthermore, some or all of these functional units may be realized by hardware such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field-Programmable Gate Array), or may be realized by a combination of software and hardware.

[0018] The registration unit 102 registers personal information of the user. The personal information is information that identifies the user and may include, for example, information about the terminal device owned by the user. The acquisition unit 104 acquires evacuee information that identifies the evacuee and safety information that indicates the safety of the evacuee from the evacuee terminal device 300. The safety information is information that includes, for example, the safety of the evacuee himself / herself, whether or not he / she is injured, and the safety of his / her family. The power supply unit 106 supplies power to the evacuee terminal device 300 identified by the evacuee information, on the condition that the acquisition unit 104 has acquired the evacuee information and safety information. The transmission unit 108 transmits the evacuee information and safety information acquired by the acquisition unit 104 to an external device. The external device is, for example, the safety confirmation system 200 or the linked device 210.

[0019] The local government terminal device 110 is a terminal device operated by an administrator of the local government, and performs processes such as viewing, modifying, and deleting evacuee information and safety information in response to operations by the administrator.

[0020] The storage unit 120 is realized by, for example, a hard disk drive (HDD), a solid state drive (SSD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a read only memory (ROM), or a random access memory (RAM), or a hybrid storage device using a combination of these. Part or all of the storage unit 120 may be realized by an external storage device accessible via various networks. An example of an external storage device is a network attached storage (NAS) device. The storage unit 120 stores the evacuee information and safety information acquired by the acquisition unit 104, and information necessary for the operation of the wireless power supply management device 100.

[0021] The power transmission device 130 is a device that is installed in an evacuation shelter and wirelessly supplies power to the evacuee terminal device 300. The power transmission device 130 communicates with the evacuee terminal device 300 and also communicates with the wireless power supply management device 100, supplies power to the evacuee terminal device 300, and transmits evacuee information and safety information obtained from the evacuee terminal device 300 to the wireless power supply management device 100.

[0022] The temporary base station 140 is a base station device that allows the wireless power supply management device 100 to communicate with the safety confirmation system 200 and the destination device 210 .

[0023] The safety confirmation system 200 includes a server device that communicates with the wireless power supply management device 100 and performs processing to provide a safety confirmation service. The safety confirmation system 200, for example, acquires evacuee information and safety information from the wireless power supply management device 100 and transmits the evacuee information and safety information to the emergency contact points of the evacuee. The cooperation destination device 210 is a terminal device managed by a cooperation destination of the wireless power supply management device 100. The cooperation destination of the wireless power supply management device 100 has the authority to view the evacuee information and safety information of, for example, local governments, police, fire departments, etc. other than the local government that manages the wireless power supply management device 100.

[0024] FIG. 2 is a diagram illustrating an overview of a power supply system 1 according to an embodiment. Disaster response equipment including the power transmission device 130, temporary base station 140, wireless power supply management device 100, and memory unit 120 is installed in municipal facilities, schools, etc. during normal times, not during disasters. The municipality performs pre-settings on the wireless power supply management device 100. When a disaster occurs, evacuees take refuge in municipal facilities, operate the evacuee terminal device 300 to input evacuee information and safety information into the wireless power supply management device 100, and receive power from the power transmission device 130. The wireless power supply management device 100 cooperates with the safety confirmation system 200 and the cooperation destination device 210, and provides evacuee information and safety information to emergency contacts, the fire department, the police, etc.

[0025] FIG. 3 is a sequence diagram showing an example of the advance registration process of the power supply system 1 according to the embodiment. In normal times, the wireless power supply management device 100 operates in a normal mode and functions as a membership system that registers member information of the power supply system 1. In the event of a disaster, a disaster victim activates a normal mode function in the application software for evacuees. The evacuee terminal device 300 transmits pre-registration information S100 to the wireless power supply management device 100. The pre-registration information S100 is information specific to the user of the evacuee terminal device 300, such as the user's name, telephone number, email address, device information (MAC address), and emergency contact information. The evacuee terminal device 300 also transmits information S102, for example, information on other terminal devices owned by the user and information on other terminals owned by other people, such as the user's family, to the wireless power supply management device 100. The registration unit 102 registers the pre-registration information S100 and information on other terminal information S102 acquired from the evacuee terminal device 300 in the storage unit 120 (step ST10).

[0026] The wireless power supply management device 100 transmits other terminal registration information S104, which includes link information and password information for registering other terminals, to the other terminal devices. The other terminal devices start application software using the link information included in the other terminal registration information S104, enter a password, and transmit password information S106 to the wireless power supply management device 100. Figure 4 is a diagram showing an example of a display screen of the evacuee terminal device 300 in this embodiment. The wireless power supply management device 100 registers information about the user corresponding to the other terminal device, such as the user name, telephone number, email address, device information (MAC address), and emergency contact information, as disaster information S108. The disaster information S108 is information used by the wireless power supply management device 100 in disaster mode.

[0027] FIG. 5 is a sequence diagram showing an example of a process performed by the power supply system 1 in the embodiment during a disaster. In the event of a disaster, the evacuee terminal device 300 activates a disaster mode function in the evacuee application software in response to an operation by a disaster victim (step ST200). The evacuee terminal device 300 transmits a disaster mode activation request S10 to the wireless power supply management device 100 in response to activating the disaster mode function. The wireless power supply management device 100 activates disaster mode in response to receiving the disaster mode activation request S10, and transmits a search request S12 to the power transmission device 130. The search request S12 is a request to search in advance for a power transmission device 130 that can be connected to the wireless power supply management device 100. Note that PTx in FIG. 5 is a power transmission function that is activated in the disaster mode of the power transmission device 130, and PRx is the evacuee terminal device 300 that receives power from the power transmission device 130. These are information linking functions in the disaster mode. The power transmission device 130 (PTx) returns a connection request S14 in response to the search request S12 received from the wireless power supply management device 100.

[0028] In response to receiving a connection request S14 from the power transmission device 130, the wireless power supply management device 100 transmits a safety information registration request S16 to the evacuee terminal device 300. In response to receiving the safety information registration request S16, the evacuee terminal device 300 pops up a safety information registration screen. The wireless power supply management device 100 may transmit the safety information registration request S16 to the evacuee terminal device 300 via the power transmission device 130, for example, or may transmit the safety information registration request S16 to the evacuee terminal device 300 via an access point at the evacuation shelter, or may output a voice prompting the evacuee terminal device 300 to register the safety information.

[0029] The evacuee terminal device 300 transmits safety information S18 to the wireless power supply management device 100 in response to an operation by the evacuee. The wireless power supply management device 100 transmits information sharing S20 of the safety information to the safety confirmation system 200 in response to acquiring the safety information. The information sharing S20 of the safety information includes evacuee information and safety information. The acquisition unit 104 may acquire emergency contact information indicating emergency contacts from the evacuee terminal device 300. The emergency contacts may be registered during normal times, or may be additionally registered in the event of a disaster. The transmission unit 108 can transmit the evacuee information and safety information to the safety confirmation system 200 and the coordinated device 210 corresponding to the emergency contacts.

[0030] During a disaster, the radio wave environment around the wireless power supply management device 100 may be poor, making it impossible to communicate between the wireless power supply management device 100 and the safety confirmation system 200 or the destination device 210. For this reason, the storage unit 120 may store evacuee information and safety information for each evacuee. The transmission unit 108 can transmit the evacuee information and safety information stored in the storage unit 120 when it detects that the radio wave environment at the evacuation shelter has been restored.

[0031] When the safety confirmation system 200 receives the information sharing request S20 for safety information, it transmits an information sharing request S22 including the evacuee information and safety information to the destination device 210, and the destination device 210 acquires the evacuee information and safety information. This allows the destination device 210 to allow relevant parties, such as emergency contact users and the police, to view the evacuee information and safety information. The destination device 210 can also verify the safety information against missing person information held by the police and fire departments to confirm the safety of people being searched for as missing. The destination device 210 provides the evacuee information in response to, for example, password information provided by a registered emergency contact. The destination device 210 may also provide a service such as a bulletin board posting information about distant family members while protecting their personal information.

[0032] The normal mode function of the wireless power supply management apparatus 100 generates a power supply request S24 in response to acquiring safety information from the evacuee terminal device 300, and passes the power supply request S24 to the disaster mode function of the wireless power supply management apparatus 100. The disaster mode function of the wireless power supply management apparatus 100 transmits a terminal information notification S26 including terminal information to the power transmitting apparatus 130. The PTx of the power transmitting apparatus 130 transmits a beacon request S28 to the evacuee terminal device 300 (PRx). The evacuee terminal device 300 (PRx) replies with a response S30 to the PTx of the power transmitting apparatus 130 based on responses from the surrounding evacuee terminal devices 300, and the PTx of the power transmitting apparatus 130 transmits a response S32 to the wireless power supply management apparatus 100.

[0033] In response to receiving a response S30 from the refugee terminal device 300, the wireless power supply management device 100 transmits a power transmission request S34 to the power transmission device 130 if the refugee terminal device 300 that transmitted the response S30 is the refugee terminal device 300 that provided the refugee information and safety information. The PTx of the power transmission device 130 starts transmitting power to the refugee terminal device 300 and transmits a power transmission start notification S36 to the refugee terminal device 300 (PRx). Since the refugee terminal device 300 is being supplied with power from the power transmission device 130, the refugee terminal device 300 (PRx) transmits a power supply start notification S38 to the wireless power supply management device 100. This allows the wireless power supply management device 100 to share the power transmission status with the refugee terminal device 300.

[0034] The wireless power supply management device 100 may, for example, acquire information about the charge amount of the battery 308 in the evacuee terminal device 300 when the disaster mode activation request S10 is received. If the charge amount of the evacuee terminal device 300 is equal to or less than a threshold, the power supply unit 106 starts supplying power to the evacuee terminal device 300 even if the acquisition unit 104 has not acquired evacuee information and safety information. If the charge amount of the evacuee terminal device 300 exceeds the threshold, the power supply unit 106 transmits information (safety information registration request S40) to the evacuee terminal device 300 prompting the evacuee terminal device 300 to input evacuee information and safety information. The wireless power supply management device 100 may, for example, transmit the safety information registration request S40 when the charge amount of the evacuee terminal device 300 increases by 10% compared to before charging. This allows the wireless power supply management device 100 to acquire safety information S42 from the evacuee terminal device 300. In response to acquiring the safety information S42, the wireless power supply management device 100 can transmit the safety information to the safety confirmation system 200 as an information linkage S44, and the safety confirmation system 200 can transmit an information linkage request S46 to the cooperation destination device 210.

[0035] When the safety confirmation system 200 receives the information linking S20 of the safety information, it transmits an information linking request S22 including the evacuee information and the safety information to the destination device 210, and the destination device 210 acquires the evacuee information and the safety information.

[0036] The acquisition unit 104 may acquire evacuee proxy information, safety information, and emergency contact information (S48) of a person represented by an evacuee from the evacuee terminal device 300. The transmission unit 108 transmits information linkage S50 including the evacuee proxy information, safety information, and emergency contact information to the safety confirmation system 200 corresponding to the emergency contact, and the safety confirmation system 200 transmits an information linkage request S52 to the destination device 210. For example, for people who do not have evacuee terminal devices 300, such as elderly people or children, a person who has the evacuee terminal device 300 can transmit a response to the wireless power supply management device 100 on their behalf. In this case, the proxy only needs to transmit minimum information such as the name, residential area, and safety information, from the perspective of protecting personal information.

[0037] As described above, the power supply system 1 according to the embodiment can acquire evacuee information and safety information from the evacuee terminal device 300, supply power to the evacuee terminal device 300 of the evacuee identified by the evacuee information upon acquisition of the evacuee information and safety information, and transmit the evacuee information and safety information to external devices such as the safety confirmation system 200 and the destination device 210. The power supply system 1 can supply power to evacuee terminal devices 300 carried by the evacuee while acquiring evacuee information, regardless of the wiring conditions at the evacuation center during a disaster. This allows the power supply system 1 to supply power to the evacuee terminal device 300 carried by the evacuee and easily collect safety information about the evacuee and link with external devices, thereby reducing the burden on local governments for information sharing. Furthermore, the power supply system 1 can collect evacuee information and safety information using the wireless power supply management device 100 even in poor radio wave conditions at the evacuation center, and transmit the safety information to emergency contacts, the evacuee's company, etc., utilizing the local government's environment.
