To determine whether a person is a registered person. It also has an application that unlocks/locks the smart lock device 2, and is transmitted when it receives access from a mobile phone or the like that satisfies a predetermined condition.

The intercom cordless handset 1 may communicate with the smart lock device 2 via the communication network 6, or may be connected to each other via a transmission line. In addition, if the device to which the call signal is transmitted by the call operation of the intercom cordless handset 1 is the intercom main unit installed in the dwelling unit, it may be connected by a transmission line, but the call signal is sent to the administrator's mobile phone or the like. is transmitted, communication is performed via the communication network 6 .
Further, the intercom cordless handset 1 communicates with the cloud server 4 via the communication network 6 .

The smart lock interlocking system configured as described above operates as follows.
First, when using a dwelling unit as a private lodging, the user makes a contract with the manager according to a predetermined procedure. At that time, the user's face image is registered and stored in the cloud server 4. - 特許庁On the other hand, the user downloads from the cloud server 4 via the communication network 6 and installs an application for unlocking/locking the smart lock device 2 at the entrance door of the dwelling unit of the lodging place into his/her mobile phone 3 . By installing this application, it is possible to unlock (or lock) the smart lock device 2 by short-range wireless communication based on Bluetooth (registered trademark) by performing a predetermined operation.
In addition, when a plurality of contractors stay in one dwelling unit, a plurality of person images are registered.

When the user thus contracted performs a special operation (here, a long press for 3 seconds) on the call button 11 of the intercom slave unit 1, the slave unit CPU 17 recognizes this as an authentication operation and shifts to the authentication mode. When shifting to the authentication mode, the camera 13 is activated without sending a call signal, and the captured image is sent to the cloud server 4 via the communication network 6 to perform image authentication.
The cloud server 4 that has received the captured image compares it with the contractor's image registered in association with the operated intercom slave unit 1, and returns an unlocking permission signal to the intercom slave unit 1 when they match.
However, when the call button 11 of the intercom slave unit 1 is pressed for a short time of about 1 second (less than 3 seconds), a normal intercom operation is performed and a call signal is transmitted to the intercom master unit or the like.

Upon receiving the unlocking permission signal, the intercom slave unit 1 shifts the smart lock device 2 from the unlocking prohibition mode to the unlocking enable mode. The smart lock device 2 that has shifted to the unlockable mode performs unlocking control upon receiving a predetermined short-range wireless signal.
Then, the intercom cordless handset 1 causes the LED 15 to perform a specific issuing operation, for example, blinking, to notify the operator that the unlocking operation of the smart lock device 2 has become possible after being authenticated to the operator.
However, even if the smart lock device 2 is shifted to the unlockable mode, the intercom cordless handset 1 unlocks the smart lock device 2 again after a certain period of time, such as 60 seconds, regardless of whether or not the unlocking operation is performed. Switch back to forbidden mode. Also, the unlocked electric lock 21 is locked under the control of the smart lock CPU 28 after a certain period of time, such as 10 seconds, has elapsed without receiving a locking operation.

The contractor, who is the operator who recognizes that the face has been authenticated by the notification operation of the LED 15, operates the mobile phone 3 to start a predetermined application, and holds it over the smart lock device 2 to unlock. . At this time, short-range wireless communication using Bluetooth (registered trademark) is performed between the mobile phone 3 and the smart lock device 2, the electric lock 21 is unlocked, and the LED 23 lights to indicate that the unlocking operation has been performed. do.

Further, the intercom slave device 1 that has shifted to the authentication mode transmits the captured image of the camera 13 to the cloud server 4 and also to the mobile phone 5 of the administrator. Therefore, the administrator can confirm the person who uses the dwelling unit from the image, and can grasp the usage situation. On the other hand, the images transmitted to the cloud server 4 are accumulated in the cloud server 4, and the administrator can view and check them from the mobile phone 5 or the like.

However, if the mobile phone 3 is held up to the smart lock device 2 and the unlocking operation is performed without facial recognition, or if an error occurs in the facial recognition, the operation is as follows.
When the short-range communication unit 22 receives the unlocking signal, the smart lock device 2 does not unlock because it is in the unlocking prohibition mode. Please perform personal authentication." to urge the unlocking operator to perform the authentication operation. This message is registered in the smart lock CPU 28 in advance.

As described above, even if the mobile phone 3 for unlocking the smart lock device 2 is carried, the entrance door can only be unlocked by the contractor whose face image is registered because face authentication is required. Therefore, it cannot be opened by a person other than the contractor, and use by a person other than the contractor can be prevented.
In addition, since it is possible to grasp that the face has been authenticated by a notification operation such as flashing of the LED 15 of the intercom slave unit 1, the contractor can unlock the door with peace of mind. There is no need to provide a separate authentication operation device.
In addition, the captured image of the camera 13 that performed the authentication operation is also transmitted to the mobile phone 5 used by the manager of the dwelling unit, and the image of the person who performed the unlocking operation is stored in the cloud server 4. Users can be confirmed, and it is easy to manage the usage status and usage history of the dwelling unit.
In addition, if the unlocking operation is performed without face authentication, the unlocking operator can recognize that the unlocking is not possible from the sounded message, and the unlocking operator can grasp that the operation is incorrect.
Even if the smart lock device 2 becomes unlockable, the unlocking operation of the smart lock device 2 is prohibited again after a certain period of time has elapsed regardless of whether or not the lock is unlocked. Since authentication is required, high security can be maintained without resetting the smart lock device 2 or the like.

In the above embodiment, the smart lock device 2 is provided with the speaker 24, and when the unlocking signal is received in the unlocking prohibition mode, the speaker 24 sounds a predetermined message. can be sounded. Since the intercom cordless handset 1 has a speaker (not shown) for communication in the communication unit 12, an announcement can be made to the unlocking operator even if the smart lock device 2 does not have the speaker 24 by using the speaker.
In addition, although the smart lock interlocking system described above is for unlocking the smart lock device 2 of a dwelling unit used for a private lodging, it can also be applied to lodging facilities such as hotels, regardless of the private lodging.
Furthermore, although a configuration has been described in which face authentication is performed by a special operation of long-pressing the call button 11 of the intercom cordless handset 1, if the intercom cordless handset 1 is not present, an authentication operation device equipped with a camera for face identification may be installed at the entrance. Alternatively, even if the intercom cordless handset 1 is present, an authentication operation device may be provided separately.
Also, although the mobile phone 5 is used as the management terminal used by the administrator, it may be a personal computer as long as it has an image display function, a display function of various information, and a call function. It may be a mobile terminal.
