[0001] The present disclosure relates to a home system, a server, a user registration initialization method, and a user registration initialization program. [Background technology]

[0002] The number of home appliances that can be connected to the Internet is increasing. Smart home systems that utilize home appliances connected to the Internet to provide residents with comfortable and convenient functions have been proposed. For example, smart locks that can remotely lock and unlock front doors using smartphones have been introduced as part of smart home systems.

[0003] When the resident of a house where a smart home system is installed changes, the users who can use the smart home system must be changed from the previous resident to the new resident. Unless the registration of users who can use the smart home system (hereinafter also referred to as "user registration") is changed appropriately, it is difficult to ensure the security of the smart home system.

[0004] A method has been proposed to ensure the security of a smart home system when the resident of a house in which the smart home system is installed changes. For example, the apartment building system described in Patent Document 1 deletes personal information stored in the residential terminal when a resident moves out.

[0040] A plurality of access points 4 may be installed in the home HO. The access point 4 may have a repeater for the wireless LAN communication WC1. Communication between the access point 4 and the relay device 3 or the like via the wireless LAN communication WC1 may go through the repeater.

[0041] [Smartphone 6] FIG. 5 is a functional block diagram of the smartphone 6. The smartphone 6 is an example of a mobile terminal or a terminal device. The mobile terminal or the terminal device is not limited to the smartphone 6, and may be, for example, a mobile phone, a smart watch, a tablet terminal, a personal computer, or the like.

[0042] As shown in FIG. 5, the smartphone 6 includes a control unit 61, a wireless communication unit 62, a touch panel 63, a camera 64, and a microphone 65.

[0043] The control unit 61 is a computer capable of executing programs, including a processor such as a CPU, a memory into which programs can be read, a storage unit into which programs and data can be stored, and an input / output control unit. The functions of the control unit 61 are realized by the processor executing a program provided to the control unit 61. The program provided to the control unit 61 is also referred to as an application. The control unit 61 controls the wireless communication unit 62, the touch panel 63, the camera 64, and the microphone 65.

[0044] The wireless communication unit 62 has an antenna and the like, and has the function of communicating via short-range wireless communication WC2 such as Bluetooth (registered trademark), ZigBee (registered trademark), or NFC (Near Field Communication), and the function of communicating via high-speed wireless communication WC3 that can connect to a network NW using a fourth-generation communication standard, a fifth-generation communication standard, or the like. The wireless communication unit 62 can communicate with the wireless communication unit 22 of the electric lock 2 via the short-range wireless communication WC2 based on instructions from the control unit 61. The wireless communication unit 62 can communicate with the device management server 8 and the user management server 9 via the high-speed wireless communication WC3 that is connected to a base station and the network NW based on instructions from the control unit 61.

[0045] The touch panel 63 is, for example, a capacitance type touch panel. An input operation input by a user to the touch panel is acquired by the control unit 61. The touch panel 63 displays a display screen based on an instruction from the control unit 61. The touch panel 63 functions as an operation unit for inputting operations and a display unit for displaying a display screen.

[0046] The smartphone 6 has installed thereon a smart home application AP, which is an application that provides comfortable and convenient functions to the user by utilizing the home equipment 1 connected to the network NW.

[0047] The smart home application AP can check the status of the household equipment 1 based on a user request. The user can check the status of the household equipment 1 using the smart home application AP whether they are at home or away from home. For example, the smart home application AP can obtain the status of the lock 20 of the electric lock 2 via the network NW and notify the user by displaying it on the touch panel 63. The user can check the locked / unlocked status of the lock 20 of the electric lock 2 using the smart home application AP whether they are at home or away from home.

[0048] The smart home application AP can generate remote control instructions for the household equipment 1. The remote control instructions for the household equipment 1 are acquired by the device management server 8 via the network NW. The household equipment 1 performs control based on the control instructions acquired via the network NW. The user can remotely control the household equipment 1 using the smart home application AP whether they are at home or away from home. For example, the user can remotely control the electric lock 2 using the smart home application AP whether they are at home or away from home.

[0049] The smart home application AP can register or change the setting information of the electric lock 2 by communicating with the electric lock 2 via the network NW or by communicating with the electric lock 2 via short-range wireless communication WC2. For example, a user can use the smart home application AP to register available key devices 5. Available key devices 5 are registered in the key information 24.

[0050] [Server 7] The server 7 is configured, for example, by one or more servers and can be connected to a network NW. The server includes hardware such as a processor such as a CPU, memory, recording media such as a hard disk or flash memory, and a communication device. The functions of the server 7 are realized by a program executed in the server's processor. The server may be an on-site server, or a cloud server that provides IaaS (Infrastructure as a Service), PaaS (Platform as a Service), SaaS (Software as a Service), or the like, or a server that combines these. In the following description, "server" includes any of the above servers.

[0051] The server 7 includes a device management server 8 and a user management server 9. The device management server 8 and the user management server 9 may be the same server.

[0052] [Device Management Server 8] The device management server 8 is a server that manages the household equipment 1. The device management server 8 acquires control instructions for the household equipment 1 that are generated in the smart home application AP. The control instructions for the household equipment 1 are acquired by the household equipment 1.

[0053] The device management server 8 acquires the status of the household equipment 1 based on a user request. The status of the household equipment 1 is acquired by the smart home application AP.

[0054] [User Management Server 9] The user management server 9 is configured by, for example, one or more servers, and is connectable to a network NW. The functions of the user management server 9 are realized by a program executed in a processor of the server.

[0055] The user management server 9 is a server that manages the registration of users who can use the home system 100 (hereinafter also referred to as "user registration"). The user management server 9 assigns a user code to a registered user. The user code is a code that is unique in the home system 100 and is a code that identifies a user in the home system 100. The user code is, for example, a user ID.

[0056] User registration is information that is recorded by associating a user code that identifies a user with the household equipment 1 that the user can use. User registration may be recorded collectively for multiple household equipment 1 installed in a home HO, or may be recorded separately for each household equipment 1. A registered user can use the associated household equipment 1.

[0057] A user of the home system 100 can obtain a user code from the user management server 9. The user code obtained by the user is registered in the smart home application AP of the smartphone 6. The user code is also recorded in the device management server 8. A control instruction for a household equipment 1 generated by the user in the smart home application AP is obtained by the device management server 8 and the household equipment 1, which are associated based on the user code.

[0058] Next, a description will be given of the operation of the home system 100. Hereinafter, the operation of the home system 100 will be described with reference to a sequence diagram of the home system 100 shown in FIG.

[0059] In step S110, the server 7 transmits a request to the first housing equipment 1A to check the status of the first housing equipment 1A based on a request from the user.

[0060] In step S120, the relay device 3 transmits a request to the electric lock 2 to check the status of the first housing equipment 1A.

[0061] In step S130, the relay device 3 acquires the status of the first housing equipment 1A from the electric lock 2.

[0062] The server 7 acquires the status of the first housing equipment 1A from the relay device 3 in step S140.

[0063] In step S150, the smart home application AP of the smartphone 6 acquires the status of the first housing equipment 1A from the server 7.

[0064] In step S160, the smart home application AP of the smartphone 6 notifies the user of the state of the first housing equipment 1A by displaying it on the touch panel 63, for example.

[0065] The home system 100 may periodically perform steps S110 to S160, allowing the user to check the latest status of the first housing equipment 1A.

[0066] When the occupant of the house HO in which the home system 100 is installed changes, the new occupant usually changes the locks on the doors and other doors, so the initialization unit 27 of the electric lock 2 is used to initialize the setting information of the electric lock 2. As a result, the wireless connection information 25 of the electric lock 2 is initialized (step S200), and the electric lock 2 is no longer able to communicate with the relay device 3.

[0067] In step S210, the server 7 transmits a request to the first housing equipment 1A to confirm the status of the first housing equipment 1A based on a request from the user.

[0068] Because the relay device 3 cannot communicate with the electric lock 2 for a predetermined time or longer, it cannot send a request to confirm the status of the first housing equipment 1A to the electric lock 2. When the relay device 3 cannot communicate with the first housing equipment 1A for a predetermined time or longer, it reports to the server 7 that communication with the electric lock 2 is down (step S220). Here, "a state in which communication is not possible for a predetermined time or longer" does not include a state in which communication is not possible due to a temporary communication failure, but refers to a state in which communication is clearly not possible.

[0069] In step S230, the server 7 invalidates the registration of the user who is able to use the first housing equipment 1A. The previous resident who was registered as a user can no longer use the first housing equipment 1A.

[0070] The server 7 may invalidate the registration of a user who can use the second housing equipment 1B and home electric appliance 1C installed in the home HO where the first housing equipment 1A is installed. The previous resident who was registered as a user will no longer be able to use any of the housing equipment 1 installed in the home HO.

[0071] Even if a resident of the house HO accidentally initializes the setting information of the electric lock 2 or if the resident of the house HO intentionally initializes the setting information of the electric lock 2, the registration of the user who can use the first housing equipment 1A will be invalidated. However, if the resident of the house HO registers as a user again, the resident of the house HO will be able to use the electric lock 2.

[0072] According to the home system 100 of this embodiment, a new resident of a home can easily and safely begin using the home system 100 as a user. The new resident can invalidate the user registration for the home equipment 1 of the home HO simply by initializing the setting information of the electric lock 2 to replace the locks on the doors, etc., and can prevent the previous resident from using the home equipment 1.

[0073] Although a resident may accidentally initialize the setting information of the electric lock 2 or may intentionally initialize the setting information of the electric lock 2, the home system 100 prioritizes ensuring security and invalidates the user registration for the home equipment 1 of the home HO.

[0074] The user registration is updated appropriately when a new resident of the house HO applies for user registration to the user management server 9. However, even before the user registration is updated, the user registration for the housing equipment 1 of the house HO can be easily invalidated by simply initializing the setting information of the electric lock 2.

[0075] If the server 7 invalidates the user registration for all household equipment 1 installed in the home HO with which it is unable to communicate with the electric lock 2 for a predetermined period of time or longer, the previous resident will no longer be able to use any of the household equipment 1 installed in the home HO. Therefore, a new resident of the home HO can easily and safely start using the home system 100.

[0076] While one embodiment of the present disclosure has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment and includes design modifications within the scope of the present disclosure. Furthermore, the components shown in the above-described embodiment and modifications can be configured in any suitable combination.

[0077] The programs for the smartphone 6, server 7, and the like are recorded on a computer-readable recording medium. The programs recorded on the recording medium are loaded into a computer system and executed. The term "computer system" as used herein includes hardware such as an OS and peripheral devices. Furthermore, "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into computer systems.
