Description

Smart door system {SMART DOOR SYSTEM}

The present invention relates to a smart door system that performs primary authentication and unlocks a corresponding door according to a user type obtained based on a result of primary authentication.

The existing front door has a mechanical door lock and functions only as a locking means and an opening/closing means.

However, recently, electronic door locks or digital door locks have been developed to provide easy-to-use lock/unlock functions. Also, smart doors that provide various information and aesthetic elements and perform crime prevention functions are emerging. .

In addition, evolving from the conventional method of performing authentication using a button key, a smart door using a simple and secure authentication method such as biometric authentication has recently appeared.

Meanwhile, many households deliver milk or dairy products in the early morning. Recently, as the number of nuclear families, the increase in single families, and the increase in women's social life, various delivery food services such as vegetables and fruits are used as well as dairy products.

However, if you are away from home for a long time, such as a summer vacation or a holiday, the delivered food is often spoiled or spoiled because it cannot maintain its freshness. In particular, the average annual temperature is increasing due to global warming, and accordingly, the need to keep the delivered food fresh from spring to autumn as well as summer is increasing.

In this regard, Korean Patent Application Laid-Open No. 10-2011-0033394 (March 31, 2011) discloses a front door and a refrigerator attached to the front door.

At least one or both of the heat absorbing fan 23 and the heat dissipating fan 25 may be an axial fan or a centrifugal fan.

The cold sink 22 includes a sink body and a plurality of heat exchange fins arranged on the front surface of the sink body. A rear surface of the sink body is in close contact with a front surface of the thermoelectric element 21 , and a rectangular fin of the heat exchange fin is disposed perpendicular to the front surface of the sink body. The plurality of heat exchange fins are spaced apart from each other in a width direction of the sink body. Accordingly, the cold air inside the storage chamber 101 sucked in by the heat absorbing fan 23 collides with the front surface of the sink body and then disperses and flows in the vertical direction through the flow path formed between the plurality of heat exchange fins. The cold air cooled while exchanging heat with the cold sink 22 passes through the discharge grill 171 formed on the guide plate 17 along the internal air guide 18 and is then supplied to the storage chamber 101 .

It may include a plurality of heat exchange fins arranged to be spaced apart.

Since the heat sink 24 must have a greater heat exchange amount than the cold sink 22 , it may have a larger volume than the cold sink 22 , and a heat transfer means such as a heat pipe may be additionally mounted therein. This is due to the physical property that the cooling capacity of the thermoelectric element decreases as the temperature difference between the heat absorbing surface and the heat generating surface increases. Accordingly, in order to maximize the cooling power of the thermoelectric element 21 , the heat dissipation capability of the heat sink 24 is set to be greater than the heat absorption capability of the cold sink 22 .

In addition, since the heat exchange fins of the heat sink 24 extend in the horizontal direction and are vertically spaced apart, the external air (indoor air) sucked by the heat dissipation fan 25 is applied to the surface of the sink body of the heat sink 24 . After colliding, the flow splits in the left and right directions.

In particular, the heat radiation air that collides with the lower heat sink 24 and exchanges heat is guided to flow divided into left and right sides of the heat radiation cover 15 while colliding with the bottom surface of the external air guide 16 .

Meanwhile, the condensed water formed on the surface of the cold sink 22 flows down to the bottom of the evaporation chamber 102 , and then is collected into the drain pan 14 through the drain hose 141 . The drain hose 141 extends from the bottom of the inner case 112 defining the bottom of the evaporation chamber 102 through the cabinet 11 to the drain pan 14 .

On the other hand, hereinafter, that authentication is completed may mean that authentication is successful.

Meanwhile, the display may be installed on the entrance door. In addition, the display may include an external display installed on the outdoor side of the front door and an internal display installed on the indoor side of the front door.

The term “displayed” used below may mean being displayed on an external display.

Meanwhile, the smart door system may further include a middle door installed inside the entrance door. In this case, the Chinese text may include a Chinese text display.

Meanwhile, referring to FIG. 10 , a user is positioned in front of the smart door system.

Here, the front of the smart door system may mean an outdoor side direction from the smart door system including the storage and entrance door.

Meanwhile, the user may be a resident. Here, the resident may be a person living in a space in which the smart door system is installed or a person using the space in which the smart door system is installed. For example, a resident may be a family member of a house where the smart door system is installed, or may be an employee of an office where the smart door system is installed.

Users may also be non-residents. For example, the user may be a courier driver who has come to deliver goods. For another example, the user may be a friend of a family member who wants to visit a space where the smart door system is installed.

Meanwhile, the smart door system needs to perform different operations according to the type of the user in front of the smart door system. Therefore, hereinafter, how the smart door system determines the type of the user and what operation is performed according to the type of the user will be described.

First, the processor may perform primary authentication for the user using authentication data.

Specifically, the sensing unit 220 of the smart door system 200 may acquire authentication data for user authentication.

Here, the authentication data may be biometric data. And by using any one of various sensors, the sensing unit 220 of the smart door system 200 may acquire the user's biometric data.

Meanwhile, the user's authentication data is not limited to biometric data, and data that can authenticate the user and distinguish a specific user from other users is sufficient. However, in the following description, it is assumed that the authentication data is biometric data.

Meanwhile, the processor of the smart door system 200 may authenticate the user based on the authentication data obtained from the sensing unit 220 .

As an embodiment, when the registered user's biometric data is stored in the authentication server, the processor of the smart door system 200 may transmit the visitor's biometric data obtained by the sensing unit 220 to the authentication server through the communication unit.

In this case, the authentication server may perform authentication using the biometric data received from the smart door system 200 and the visitor's biometric data stored in the server.

Specifically, the server may compare the biometric data of registered users with the biometric data received from the smart door system 200 . In addition, when the biometric data of a specific visitor among the biometric data of registered visitors and the biometric data received from the smart door system 200 match, the server may transmit an authentication result indicating that authentication is successful to the smart door system 200 .

Meanwhile, although it has been described that the authentication is performed in the authentication server and the authentication server transmits the authentication result and visitor information to the smart door system 200, the present invention is not limited thereto.

Specifically, when the registered user's biometric data is stored in the smart door system 200 , the processor of the smart door system 200 performs the biometric data obtained by the sensing unit 220 and the registered user's biometric data stored in the memory 250 . Authentication can be performed using data.

Specifically, the processor of the smart door system 200 may compare the biometric data stored in the memory with the biometric data obtained by the sensing unit 220 . And when the biometric data of a specific visitor among the biometric data stored in the memory and the biometric data acquired by the sensing unit 220 match, the processor of the smart door system may determine that authentication is successful.

Meanwhile, the processor of the smart door system may determine that authentication has failed.

Specifically, when the biometric data of the registered user and the biometric data obtained by the sensing unit 220 do not match, the processor of the smart door system may determine that authentication has failed.

Meanwhile, the biometric data may be image data captured by the user.

Specifically, the sensing unit 220 may include a camera, and the camera may be arranged to photograph the front of the smart door system.

In addition, the processor may control the camera to photograph the user located in front of the smart system. In addition, the processor may perform the first authentication using the image captured by the user by the camera.

Specifically, when the image data captured by the user corresponds to the registered image data, the processor may determine that the first authentication is successful. On the other hand, when the image data captured by the user does not correspond to the registered image data, the processor may determine that the primary authentication has failed.

For example, when the primary authentication method is face or body recognition, the processor compares the user's face or body in the image acquired through the sensing unit with a previously registered face or body to determine whether the primary authentication succeeds. have.

Meanwhile, the processor may acquire the type of the user based on the result of the primary authentication. Here, the type of user may include a resident or a non-resident.

Specifically, as described above, the processor may perform primary authentication for the user using authentication data and previously registered authentication data.

In this case, the resident's authentication data may have been previously registered. Therefore, if the first authentication is successful, the processor may determine the type of the user in front of the smart door system as a resident.

On the other hand, authentication data of non-residents may not have been previously registered. Accordingly, if the primary authentication fails, the processor may determine the type of the user in front of the smart door system as a non-resident.

Meanwhile, the processor may perform an operation corresponding to the type of the user.

First, an operation when the user is a resident will be described with reference to FIGS. 11 to 15 .

11 to 15 are diagrams for explaining an operation when the user is a resident.

Referring to FIG. 11 , the processor is currently displaying the main screen on the display 1110 .

Here, the main screen may include a status display window 1120 , a main window 1130 , a bell menu, and a courier storage menu 1150 .

Meanwhile, the processor may unlock the door corresponding to the user's type.

Specifically, when the type of the user is a resident, the processor may unlock the front door.

In this case, the processor may additionally perform secondary authentication when the primary authentication is completed, and unlock the front door when the secondary authentication is successful. Specifically, the fact that the user's type is determined to be a resident means that the primary authentication has already been successful. And the processor can unlock the front door when the second authentication is successful.

That is, the processor may unlock the front door when the complex authentication including the primary authentication and the secondary authentication succeeds.

Specifically, referring to FIG. 12A , when the first authentication is successful and it is determined that the user type is a resident, the processor may display a screen for guiding the second authentication.

More specifically, referring to FIG. 11 , the main screen is currently displayed, and the primary authentication is performed while the main screen is displayed. In addition, when the first authentication is successful and it is determined that the type of the user is a resident, the processor may switch the main screen to a screen for guiding the second authentication.

When the type of user is a resident, the processor may acquire the second authentication data through the sensing unit.

For example, when the secondary authentication means is vein authentication, the processor may display an image 1210 indicating a method of vein authentication and a message 1120 indicating a method of vein authentication.

Also, the vein authentication may be performed by photographing the body using the vein recognition camera 1230 . In this case, the processor may control the lighting device 1220 surrounding the vein recognition camera 1230 to be turned on.

Meanwhile, referring to FIG. 12B , when the user's body is photographed through the camera 1230 , the processor may display a preview screen 1240 of an image received through the vein recognition camera 1230 .

In addition, the processor may display a message 1270 indicating that the second authentication data is being acquired.

Meanwhile, the processor may perform second authentication of the resident using the second authentication data.

For example, when the second authentication data is vein data, the processor may perform secondary authentication using the vein data received through the camera and the previously registered vein data.

12C is a diagram illustrating a screen when secondary authentication is successful.

When the second authentication is completed, that is, when the second authentication data obtained through the sensing unit corresponds to the previously registered authentication data, the processor may display a message 1120 indicating that the authentication is completed.

In addition, the processor may determine a resident in front of the smart door system using the second authentication data, and display identification information indicating the determined resident. For example, if the resident in front of the smart door system is a father, the processor may display an image 1260 of the father or a text 1261 indicating the father.

Meanwhile, when the second authentication is completed, the processor can unlock the front door.

Specifically, when the second authentication data corresponds to the previously registered authentication data, the processor may control the front door lock 261 to unlock the front door. Also, when an input of touching the handle of the front door is received, the processor may open the front door.

Meanwhile, when the first authentication fails, that is, when the user is a non-resident, the processor may not acquire the second authentication data.

For example, even if a non-resident places a body on the vein recognition camera 1230 , the processor may not perform photographing using the vein recognition camera 1230 .

Meanwhile, the second authentication data may be a different type of data from the first authentication data.

For example, when the first authentication data is image data for face and body recognition, the second authentication data may be image data for vein recognition.

For another example, when the first authentication data is image data for iris recognition, the second authentication data may be image data for vein recognition.

As another example, when the first authentication data is image data for face and body recognition, the second authentication data may be DNA data for DNA recognition.

Meanwhile, the first authentication data may be image data for face or body recognition. In addition, the second authentication data may be at least one of biometric data, a personal password corresponding to a resident, a common password of a plurality of residents, an NFC signal allocated to the resident's terminal, and an RF signal of a key possessed by the resident.

13 is a diagram for explaining a method of inputting a personal password corresponding to a resident.

A plurality of personal passwords respectively corresponding to a plurality of residents may be stored in the memory or server of the smart door system.

As such, the personal password stored in the memory or the server may be referred to as a registered personal password.

For example, a personal password corresponding to the father, the mother's personal password, and the son's personal password may be registered.

Meanwhile, when the primary authentication is completed, the processor may determine who the resident in front of the smart door system is. For example, when the primary authentication data corresponds to the father's registered authentication data, the processor may determine that the resident in front of the smart door system is the father.

Meanwhile, when the primary authentication is completed, the processor may display an image, a keyboard, and an input window for guiding input of a password corresponding to a resident in front of the smart door system.

Meanwhile, the processor may receive an input of the personal password through the sensing unit. And when the received personal password corresponds to the registered personal password of the resident in front of the smart door system, the processor may unlock the front door.

14 is a diagram for explaining a method of inputting a common password of a plurality of residents.

A common password of a plurality of residents may be stored in the memory or server of the smart door system.

As such, the common password stored in the memory or the server may be referred to as a registered common password.

Meanwhile, when the primary authentication is completed, the processor may display an image, a keyboard, and an input window for guiding input of a common password.

Meanwhile, the processor may receive an input of the common password through the sensing unit. And when the received common password corresponds to the registered common password, the processor may unlock the front door.

Meanwhile, a case in which the second authentication data is an NFC signal will be described.

In the memory or server of the smart door system, information on an NFC signal commonly assigned to the terminals of the occupants or individually assigned to each occupant may be stored. In this way, information about the NFC signal stored in the memory or the server may be referred to as a registered NFC signal.

Meanwhile, when the primary authentication is completed, the processor may receive the NFC signal transmitted from the terminal possessed by the resident through the sensing unit.

And when the received NFC signal corresponds to the registered NFC signal, the processor may unlock the front door.

Additionally, when the primary authentication is completed, the processor may receive an RF signal transmitted from a terminal possessed by the resident through the sensing unit.

And when the received RF signal corresponds to the registered RF signal, the processor may unlock the front door.

15 is a view for explaining a method for a resident to open a delivery box.

The processor may display a menu corresponding to the item storage.

In addition, when the secondary authentication for the resident is completed and a menu corresponding to the goods storage is selected, the processor may unlock the door on the outdoor side of the goods storage.

That is, the resident may wish to open only the door of the storage room without opening the front door. In addition, the processor may display a menu corresponding to the storage and, when the menu is selected, open the storage, thereby satisfying the user's request.

Meanwhile, the goods storage may include a refrigerator including a first outdoor door and a courier refrigerator including a second outdoor door.

In this case, the processor may display the first menu 1510 corresponding to the refrigerator and the second menu 1520 corresponding to the parcel storage.

Meanwhile, when the second authentication of the resident is completed and the refrigerator is selected by the resident, the processor may unlock the first outdoor door of the refrigerator.

Also, when the secondary authentication for the resident is completed and the parcel storage is selected by the resident, the processor may unlock the second outdoor door of the parcel storage.

Meanwhile, although it has been described that the lock of the goods storage is released when the secondary authentication is completed, the present invention is not limited thereto and may be implemented in a manner in which the lock of the goods storage is released when the primary authentication is completed.

For example, when it is determined that the user is a resident after the primary authentication of the user is completed, and a menu corresponding to the goods storage is selected, the processor may unlock the door on the outdoor side of the goods storage.

As another example, when it is determined that the user is a resident after the primary authentication of the user is completed, and a menu corresponding to the refrigerator is selected, the processor may unlock the door on the outside of the refrigerator.

When the front door is opened, since outsiders can enter the house, the front door requires a higher level of security than that of a courier storage or refrigerator. Therefore, it is possible to improve security by allowing the lock of the entrance door to be unlocked when both the primary and secondary authentication are completed. On the other hand, the courier storage or refrigerator requires only the first authentication, thereby improving the user's convenience.

Meanwhile, the processor may display a message or an image indicating the storage status of the parcel.

For example, the processor may display messages such as “There is no parcel in storage”, “The refrigerator is storing parcels”, “The parcel is being stored in the parcel storage”, and “The refrigerator and parcel storage are storing parcels”. can be printed out.

In addition, the processor may display a message or an image indicating the state of the goods storage.

For example, the processor may output the messages “The refrigerator is open”, “The refrigerator is closed”, “The courier box is open”, and “The courier box is closed”.

Meanwhile, the processor may perform an operation corresponding to the type of the user.

Hereinafter, an operation when the user is a non-resident will be described with reference to FIGS. 16 to 21 .

16 to 20 are diagrams for explaining an operation when a user is a courier driver among non-residents.

Referring to FIG. 16 , the processor is currently displaying the main screen on the display 1110 .

Meanwhile, the processor may display identification information of a space in which the smart door system is installed on the main window 1130 . For example, the processor may display text indicating that the space where the smart door system is installed is room 712.

In addition, the processor may display the courier storage menu 1150 .

Meanwhile, the processor may unlock the door corresponding to the user's type.

Specifically, if the user's type is a non-resident, the processor may unlock the warehouse.

In this case, the processor can unlock the goods storage only after additional authentication is completed. Specifically, if the user's type is determined to be non-resident, it means that the primary authentication has already failed. Accordingly, the processor may perform additional authentication and unlock the inventory if the additional authentication succeeds.

That is, when unlocking the front door, the processor unlocks the front door when the complex authentication including the primary authentication and the secondary authentication succeeds. However, in the case of unlocking the storage of goods, the processor may unlock the storage of goods when one authentication is successful (first authentication failure, additional authentication success).

Specifically, when the type of the user is a non-resident, the processor may acquire additional authentication data of a different type from the first authentication data through the sensing unit. Here, the additional authentication data may be a QR code or a password transmitted to a non-resident's terminal.

More specifically, referring back to FIG. 16 , the current main screen is displayed, and the primary authentication is performed while the main screen is displayed. And when it is determined that the type of the user is a non-resident because the primary authentication fails, the processor may maintain the main screen as it is. Accordingly, the courier storage menu 1150 in the main screen may be displayed as it is.

Meanwhile, when an input for selecting the delivery storage menu 1150 is received from the delivery driver, the processor may switch the main screen to a screen for guiding additional authentication.

In this case, as shown in FIG. 17 , the processor may display a screen guiding selection of an authentication method. For example, the processor may display the first menu 1710 corresponding to the QR code and the second menu 1720 corresponding to the password.

In addition, when a QR code is selected from a non-resident, the processor may display a screen for guiding additional authentication using the QR code as shown in FIG. 18 .

In addition, when a password is selected from a non-resident, the processor may display a screen for guiding additional authentication using a password as shown in FIG. 19 .

Meanwhile, when the type of the user is a non-resident, the processor may acquire additional authentication data through the sensing unit.

For example, when the additional authentication means is a QR code, as shown in FIG. 18 , the processor may display a message indicating the method of QR code authentication.

In addition, QR code authentication may be performed by using the camera 1230 to photograph the QR code transmitted to the terminal of the non-resident. In this case, the processor may control the lighting device 1220 surrounding the camera 1230 to be turned on.

Also, when the QR code displayed on the non-resident's terminal is photographed through the camera 1230 , the processor may display a preview screen 1820 of the image received through the camera 1230 .

Meanwhile, the processor may perform additional authentication for the non-resident using the additional authentication data.

Specifically, when a non-resident visits a specific smart door system, a specific QR code may be transmitted to the non-resident's terminal.

And the QR code may be stored in the memory or server of the smart door system. In this way, the QR code stored in the memory or server may be referred to as a registered QR code.

On the other hand, if the photographed QR code corresponds to the registered QR code, the processor may determine that the additional authentication is successful.

Meanwhile, when the additional authentication means is a password, as shown in FIG. 19 , the processor may display an image, a keyboard, and an input window for guiding input of the password.

Meanwhile, the processor may perform additional authentication for the non-resident using the additional authentication data.

Specifically, when a non-resident visits a specific smart door system, a password may be transmitted to the non-resident's terminal.

And the password may be stored in the memory or server of the smart door system. In this way, the password stored in the memory or server may be referred to as a registered password.

Meanwhile, the processor may receive an input of the password through the sensing unit. Specifically, the non-resident may see the password displayed on the terminal and press the keyboard displayed on the display 1110 .

On the other hand, if the input password corresponds to the registered password, the processor may determine that the additional authentication is successful.

Meanwhile, upon completion of additional authentication, the processor can unlock the locker.

Meanwhile, referring to FIG. 20 , when the goods storage includes a refrigerator and a delivery storage, the processor may display a first menu 2010 corresponding to the refrigerator and a second menu 2020 corresponding to the parcel storage.

In addition, when the additional authentication is completed and the refrigerator is selected by a non-resident, the processor may unlock the first outdoor door of the refrigerator.

Also, when the additional authentication is completed and the parcel storage is selected by the non-resident, the processor may unlock the second outdoor door of the parcel storage.

Meanwhile, although it has been described as receiving an input for selecting a refrigerator or a courier storage from a non-resident, it is not limited thereto.

Specifically, the additional authentication data (QR code or password) may include information on the characteristics of the article (necessary refrigeration, no refrigeration).

And when the characteristic of the article is refrigeration required and additional authentication is completed, the processor may unlock the first outdoor door of the refrigerator.

On the other hand, when the characteristic of the article is that refrigeration is not required and additional authentication is completed, the processor may unlock the second outdoor door of the parcel storage.

Meanwhile, if the first authentication fails, the processor may photograph the non-resident through the camera. In this case, the processor may transmit the image captured by the camera to the server or the terminal of the resident. In addition, the processor may display a preview screen including an image captured by the camera.

On the other hand, the storage of goods may be set to be always open. Here, the "normally open" may mean unlocking the door on the outdoor side of the goods storage without additional authentication.

In addition, when the normal opening of the storage unit is set, the processor may unlock the door on the outdoor side of the storage unit without additional authentication for non-residents.

For example, when the first authentication fails, the processor may display the first menu 2010 corresponding to the refrigerator and the second menu 2020 corresponding to the delivery storage.

And when the refrigerator is selected by a non-resident, the processor may unlock the first outdoor door of the refrigerator. Also, when the parcel storage is selected by a non-resident, the processor may unlock the second outdoor door of the parcel storage.

21 is a diagram for explaining an operation when a user is a visitor among non-residents.

If the primary authentication fails, the main screen is displayed as it is. In addition, the main screen may include a bell menu 1140 and a delivery storage menu 1150 .

In the case of a delivery driver, additional authentication may be performed by pressing the delivery storage menu 1150 . However, in the case of a visitor, there is no need to proceed with additional authentication, and the bell menu 1140 is pressed.

Meanwhile, when the bell menu 1140 is selected, the processor may control a speaker in the space in which the smart door system is installed to output a bell sound, or transmit a call (or video call) request to the resident's terminal or to a Chinese door.

Meanwhile, when the visitor does not select the bell menu 1140 , the processor may display an image or message 2110 for guiding the selection of the bell menu.

For example, if the first authentication fails three or more times and additional authentication does not proceed, the processor may display an image or message 2110 for guiding the selection of the bell menu.

22A to 22B are diagrams for explaining another operation when the primary authentication fails.

When the primary authentication fails, the processor may display a cancel menu 2210 , a retry menu 2220 , and a password authentication menu 2230 .

And when the cancel menu 2210 is selected, the processor may display a basic screen.

Meanwhile, even if the user in front of the smart door system is a resident, the primary authentication may fail. For example, if there is a problem in the system or if the face recognition is not well due to the shooting angle, the primary authentication may fail.

In addition, the resident who wants to try the primary authentication again may select the retry menu 2220 .

Meanwhile, when an input for selecting the retry menu 2220 is received, the processor may receive first authentication data and perform primary authentication using the first authentication data.

Meanwhile, the processor may perform the primary authentication a preset number of times, and when the preset number of authentication fails, determine that the primary authentication has failed.

For example, the processor may perform the primary authentication 5 times, and when the 5 times of authentication fail, it may be determined that the primary authentication has failed.

Similarly to the second authentication, the processor may perform the second authentication a preset number of times, and when the preset number of authentication fails, determine that the secondary authentication has failed.

For example, the processor may perform the second authentication 5 times, and if the authentication fails 5 times, it may be determined that the second authentication has failed.

On the other hand, the number of authentication failures in the primary authentication may not affect the number of authentication failures in the secondary authentication.

For example, if the first authentication is successful after the 5th attempt after 4 failures, the programmer can perform the secondary authentication. In this case, instead of performing the second authentication once and determining that the second authentication has failed if the first authentication fails, the processor performs the second authentication five times and determines that the second authentication has failed if the fifth authentication fails. can

Meanwhile, a user who wants to authenticate with a password instead of retrying the primary authentication may select the password authentication menu 2230 .

In this case, the processor may display the keyboard as shown in FIG. 22B , and when the received password corresponds to a previously registered password, the processor may unlock the front door.

23 is a diagram for explaining authentication using a temporary password.

The smart door system is operated by an external power source. However, when the external power is cut off due to a power outage, the smart door can be operated using the internal battery. On the other hand, when operating using an internal battery, authentication using biometric data may not be possible. In addition, when operating using an internal battery, even if authentication using biometric data is possible, there is a need to avoid authentication using biometric data in order to reduce power consumption.

On the other hand, the application installed on the server or the resident's terminal may generate a temporary password at a preset period. This temporary password may be updated at a preset period.

Meanwhile, when the temporary password is generated, the temporary password may be shared between the smart door system and the resident's terminal. That is, when the resident's terminal generates a temporary password, the resident's terminal may transmit the temporary password to the smart door system. In addition, when the server generates a temporary password, the server may transmit the temporary password to the smart door system and the resident's terminal.

Meanwhile, the processor may receive a temporary password updated at a preset period from the server or the resident's terminal. And, by storing the received temporary password in the memory, the processor may register the received temporary password.

Meanwhile, referring to FIG. 23 , in a low-power situation (when the external power is cut off or when operating with an internal battery), the processor may display a message guiding input of a temporary password and a keyboard. In this case, the processor may not perform primary authentication and secondary authentication.

Meanwhile, the resident can see the temporary password displayed on his/her terminal and input the temporary password.

Meanwhile, when the registered temporary password is received through the sensing unit, the processor may unlock the front door.

As described above, according to the present invention, there is an advantage in that it is possible to prevent a situation in which a resident cannot enter the interior in a low power situation.

Meanwhile, although it has been described that authentication is performed using a temporary password in a low power situation, the present invention is not limited thereto, and authentication may be performed using a common password.

Specifically, in a low power situation (when external power is cut off or when operating with an internal battery), the processor may display a message guiding input of a common password and a keyboard. In this case, the processor may not perform primary authentication and secondary authentication.

And when the registered common password is received through the sensing unit, the processor may unlock the front door.

Meanwhile, the control command generated in the smart door system may be generated in the resident's terminal. Specifically, an application for controlling the smart door system may be installed in the resident's terminal. Also, the resident's terminal may generate a control command based on an input received from the resident and transmit the generated control command to the smart door system. In this case, the processor may perform an operation corresponding to the received control command.

Meanwhile, the setting value set in the smart door system may be generated in the resident's terminal. Specifically, an application for controlling the smart door system may be installed in the resident's terminal. Also, the resident's terminal may generate a setting value based on an input received from the resident and transmit the generated setting value to the smart door system. In this case, the processor may change the setting value set in the smart door system to the received setting value.

As described above, according to the present invention, there is an advantage in that the user in front of the smart door system can be distinguished through the primary authentication, and menus and operations necessary for the user can be provided.

In addition, the operation for distinguishing the user and the operation for the primary authentication are not distinguished from each other, but the user is also classified according to the result of the primary authentication. Accordingly, there is an advantage in that a menu and an operation necessary for the user can be provided without a separate input for distinguishing the user.

In addition, the classification of the user may be performed by face recognition or body recognition. That is, even if there is no separate user action or contact, the smart door system has the advantage of being able to classify users and provide necessary menus and operations to the users.

In addition, higher security is required for the entrance door, and there is an advantage in that security can be improved by performing complex authentication in order to open the entrance door. On the other hand, the courier storage or refrigerator requires only the first authentication, thereby improving the user's convenience.

In addition, when the primary authentication is performed by face recognition, the user's action for primary authentication is not required. That is, although complex authentication is actually performed, the resident feels as if only one authentication has been performed, so there is an advantage in that user convenience is increased.

Also, according to the present invention, it is possible to provide an appropriate UI based on who the user is. For example, when it is determined that the user is a resident by the primary authentication, an image guiding the preset secondary authentication method may be displayed. For another example, if the user is determined to be a non-resident by the first authentication, the smart door system provides a menu that allows you to store the parcel or press the bell as it is, and guides the storage of the parcel if courier storage is selected. video can be provided. For another example, if the user is determined to be a non-resident by the primary authentication and the non-resident does not take any action, the action of pressing a bell may be guided. That is, according to the present invention, there is an advantage of providing an intuitive UI that is suitable for a user's type.
