  FIG. 3 is a diagram showing an outline of the electric lock system 100 according to the first embodiment. The electric lock system 100 is connected to a local area network 140 including a local Wi-Fi network 141 via a Wi-Fi access point 151. The communication terminal device 153 is connected to the local Wi-Fi network 141 and performs wireless communication with the electric lock system 100. Here, the communication terminal device 153 is, for example, a portable communication terminal device that includes a display screen as a display unit, a touch panel as an operation unit, a Wi-Fi communication function, and the like. The local area network 140 is connected to an information terminal device 152 (for example, a PC) installed indoors, for example.

  FIG. 4 is a diagram for explaining an introduction method of the electric lock system 100 according to the first embodiment. First, the electric lock system 100 is installed and wired (step S101).

  Subsequently, the electric lock system 100 is connected to the local Wi-Fi network 141 using the WPS button 125 of the electric lock system 100 and the WPS button of the Wi-Fi access point 151 (step S102).

  Next, setting is performed from an information terminal device 152 (for example, a PC) connected to the local area network 140. A web page in the electric lock system 100 is displayed by a web browser provided in the information terminal device 152. Alternatively, the setting screen of the electric lock system 100 is displayed using a dedicated application installed in the information terminal device 152. Then, the initial setting of the authentication method of the communication terminal device 153 that permits the change of the initial password and the locking and unlocking is performed (step S103).

  Next, a dedicated application is installed in the communication terminal device 153 that permits locking and unlocking. And it connects to the electric lock system 100 from a dedicated application, and performs device registration so as to permit the locking and unlocking from this communication terminal device. In addition, an authentication method such as password input or fingerprint authentication is selected (step S104). The dedicated application is installed from a Web page in the electric lock system 100. Alternatively, what is disclosed on the Internet may be installed.

  In addition, step S104 is performed from all the communication terminal devices 153 used for locking / unlocking of the electric lock system 100. The electric lock system 100 is now installed and ready for use.

  FIG. 5 is a flowchart showing the operation of the electric lock system 100 according to the first embodiment. It is assumed that there is a user who has the communication terminal device 153 outside the door, and the communication terminal device 153 is within a range that can be connected to the local Wi-Fi network 141. The communication terminal device 153 is installed with the dedicated application described above.

  First, the user performs an operation of connecting the communication terminal device 153 to the local Wi-Fi network 141 (step S111). Then, the communication terminal device 153 connects to the local Wi-Fi network 141 (step S112).

  After the communication terminal device 153 is connected to the local Wi-Fi network 141, the user performs an operation of starting a dedicated application (step S113). Then, a dedicated application is activated on the communication terminal device 153 (step S114).

  The dedicated application started on the communication terminal device 153 first displays a screen requesting the user to input authentication data (step S115). The user operates the communication terminal device 153 to input authentication data (step S116). Here, the authentication data is personal authentication data for authenticating an individual, for example, a password combining characters and numbers. The personal authentication data may be data based on biometric authentication. The biometric authentication is performed by a known method. For example, when the communication terminal device 153 includes a fingerprint authentication device, the biometric authentication is performed by fingerprint authentication. For example, when the communication terminal device 153 includes a camera, authentication may be performed by face recognition.

  When the authentication data is input, the authentication data is transmitted to the electric lock system 100 together with the UUID of the communication terminal device 153 and the connection request (step S117). Here, the connection destination of the communication terminal device 153 by the dedicated application is not limited to the electric lock system 100. For example, the communication terminal device 153 is connected to an HGW (Home gate way) connected to the local area network 140, and a plurality of electric terminals are connected via the HGW. It may be connected to the lock system 100 or to a plurality of electric lock systems 100 connected to the local area network 140 without going through the HGW.

  The UUID and authentication data transmitted to the electric lock system 100 are temporarily stored in the RAM inside the microcomputer 121 (step S118). Then, the microcomputer 121 determines whether the received UUID and authentication data are correct (step S119). That is, the microcomputer 121 refers to the lock permission terminal list (FIG. 2) stored in the storage unit 123 and determines whether the received UUID and authentication data match the UUID and authentication data in the list. .

  If it is determined in step S119 that the received UUID and authentication data are not correct, the communication terminal device 153 is not the communication terminal device 153 that permits locking / unlocking, or the authentication data is incorrect. In this case, the electric lock system 100 ends the communication with the communication terminal device 153. At this time, the electric lock system 100 may transmit authentication failure information to the communication terminal device 153, and the communication terminal device 153 may display an authentication failure warning on the screen.

  On the other hand, when it is determined in step S119 that the received UUID and authentication data are correct, the electric lock system 100 notifies the communication terminal device 153 of the open state of the lock and the door at that time, and the communication terminal device 153 The open / close state is displayed on the screen (step S120).

  When the user confirms that the state of the electric lock system 100 is displayed on the screen of the communication terminal device 153, the user performs an unlocking operation (step S121). Here, the operation that can be performed by the user is not limited to unlocking, but may be, for example, a locking operation or an update request for the open / closed state of a lock or a door. The communication terminal device 153 transmits an unlocking command to the electric lock system 100 according to the unlocking operation by the user (step S122). When receiving the unlock command transmitted from the communication terminal device 153, the electric lock system 100 unlocks the electric lock 110 (step S123).

  After unlocking the electric lock 110, the electric lock system 100 notifies the communication terminal device 153 of the open / closed state of the lock and door (step S124). Then, the communication terminal device 153 updates the open / close state of the lock and the door (step S125), and displays the updated lock and door open / close state on the screen (step S126).

  In step S123, when unlocking fails for some reason, the electric lock system 100 notifies the communication terminal device 153 of unlocking failure information. Then, the communication terminal device 153 displays a warning on the dedicated application screen to notify that unlocking has failed.

  When a predetermined time has elapsed since the temporary storage of the authentication data (step S118) or the transmission of the request / command from the communication terminal device 153 (step S122), the electric lock system 100 temporarily stores it in the RAM inside the microcomputer 121. Discard the stored authentication data. Then, the communication terminal device 153 is notified that the authentication data has been discarded. The communication from the communication terminal device 153 until the authentication data is discarded to the electric lock system 100 may be configured to require the authentication data to be added every time, or the authentication data must be given only for the first time. May be omitted. The communication terminal device 153 that has received the notification of discarding the authentication data inputs the authentication data again from the authentication data input screen of the dedicated application.
