The frame 12 is a door frame installed at the entrance of the facility. This frame 12 is formed in a shape surrounding the edge of the door 11, for example, may be formed in the shape of a square ring. However, the shape of the frame 12 is not necessarily limited to a rectangular ring shape, and may be formed such as a "c" shape, a "a" shape, a "ㅣ" shape, and the like. The hinge part 13 is a connecting member that enables the door 11 to rotate while being coupled to the frame 12 . As an example, the door 11 and the frame 12 are coupled to each other facing each other, the protruding member is connected to the hinge shaft, so that the door 11 can be rotated about the hinge shaft, the hinge part 13 can be implemented. However, the hinge part 13 does not necessarily have to be implemented in this form, and there is a special limitation as long as the door 11 and the frame 12 are connected and the door 11 is rotatable about the hinge axis. there is no At least one hinge portion 13 may be provided, and may be disposed on the upper end portion, lower end portion, and a middle portion therebetween of the door 11 .

The door lock 20 is mounted on the door 11 to perform locking and opening operations of the door 11 . The door lock 20 includes a locking means for fastening the door 11 and the frame 12, so that the door 11 is fastened to the frame 12 to perform a locking operation, and unlocking the locking means to open the door 11 carry out The door lock 20 has an electric circuit, and the lock means is electrically controlled by the processor 40 to be described later. In addition to the control by the processor 40, the door lock 20 may be locked and opened by the user by inputting a password, a pattern, or biometric information, or by an electronic key.

The communication unit 30 is a communication module that wirelessly communicates with the user's communication terminal 2000 . Here, the communication terminal 2000 may have an application (APP) installed therein, and as a mobile communication device carried by the user, a smart phone or a tablet PC may be exemplified. Wireless communication includes Wi-Fi, NFC, Bluetooth, RFID, and the like. The communication unit 30 may be connected to an indoor wireless Internet or LAN line to configure a network, and necessary power may be supplied indoors, but may also be provided by a battery in preparation for an emergency.

The processor 40 is a control unit for controlling the door lock 20 , and when the user's communication terminal 2000 transmits a control signal to the communication unit 30 , based on the control signal received by the communication unit 30 , the door lock (20) to perform the locking and opening operations. Here, the control signal may be a signal generated and transmitted by an application (APP) installed in the communication terminal 2000 or a wireless signal generated in the communication terminal 2000 itself, such as Bluetooth or RFID.

For example, when the user accesses the application (APP) and inputs a door open command in a preset form such as a password, pattern, biometric information, etc., the communication unit 30 receives the door open command as a control signal, and the processor 40 may cause the door lock 20 to perform an opening operation of the door 11 in response to the door opening command. However, the door open command is not necessarily implemented in the form of a password or the like.

Meanwhile, the processor 40 may control the operation of the door lock 20 in response to the access of the communication terminal 2000 . This will be described in more detail below.

When the user's communication terminal 2000 approaches within a preset distance range, the smart door system 1000 according to an embodiment of the present invention recognizes the approach as a control signal and causes the door lock 20 to open. can do it

Since the communication terminal 2000 can perform short-range wireless communication with the communication unit 30 , the communication terminal 2000 can be recognized within an access distance in which wireless communication is possible. Therefore, when the communication terminal 2000 exists at a predetermined distance L1 where the communication terminal 2000 is not recognized, the door lock 20 maintains the locked state, and the communication terminal 2000 can be recognized. When approaching within the preset distance (L0) range, the communication unit 30 detects a signal transmitted to the communication terminal 2000, the processor 40 may cause the door lock 20 to perform an opening operation. According to the operation control method of the door lock 20 , the door 11 can be automatically opened by recognizing the user's approach even in a situation where the user's behavior is restricted, such as holding luggage.

Meanwhile, the door lock 20 does not necessarily have to be implemented to automatically open the door 11 under the control of the processor 40 , but may be implemented to manually release the lock means. For example, the door lock unit 20 may include a built-in handle 21 . The built-in handle 21 is provided so that a user can manually turn, pull, or press the handle, and an opening operation of the door 11 may be performed in response to the movement of the built-in handle 21 . The built-in handle 21 is not normally exposed to the outside, but may be exposed when a control signal is received from the communication terminal 2000 . In one embodiment, a recessed hole 14 in a concave shape is formed on one surface of the door 11 facing the outdoors, and a built-in handle 21 is built in the recessed hole 14, and then the processor ( 40), it is exposed to the outside, and an opening operation can be performed manually by the user. At this time, when the user opens the door 11 by turning or pulling the exposed handle, and the door 11 is closed after the user enters the room, it may automatically return to the original built-in state. Alternatively, the door 11 may be opened when the user presses the exposed built-in handle 21 to restore it to the original built-in position.

The built-in handle 21 may be exposed in response to a control signal of the communication terminal 2000 . Accordingly, as described above, when a door open command is input to the application (APP) or the communication terminal 2000 approaches within a preset distance (L0) range, the built-in handle 21 may be exposed.

The opening operation of the door 11 using the manual built-in handle 21 can be implemented separately from the above-described method that is automatically opened when a user approaches, but operates in a separate mode that can function in two ways Thus, the user can select and set the mode method.

Overall, according to the smart door system 1000 according to the present invention, since the locking and opening operations of the door 11 are controlled by the user's communication terminal 2000, the password or pattern leakage or loss of the electronic key is prevented. It is possible to compensate for the security loopholes caused by In addition, since the door 11 can be opened by sensing the user's communication terminal 2000 without a separate user authentication step, the user can easily enter and exit even in a situation where the user's behavior is restricted.

As shown in FIG. 7 , the smart door system 1000 according to the sixth embodiment of the present invention includes a memory 120 , a door registration code transmitter 130 , a memory 120 to interwork with a user's communication terminal 2000 , and a code authenticator 140 .

The memory 120 is a data storage medium for storing the user's ID and a device registration code for authenticating the user's communication terminal 2000 . Here, the user's ID and device registration code may be input to and transmitted to an application (APP) installed in the user's communication terminal 2000 , and may be received and stored by the communication unit 30 . The device registration code is a code capable of authenticating the communication terminal 2000 of the user, and may use the serial number of the communication terminal 2000 or may be separately generated and used by the user.

The door registration code transmitting unit 130 transmits the door registration code to the user's communication terminal 2000 when the user's ID and device registration code are received by the communication unit 30 . The door registration code is a code for authenticating the smart door system 1000 , and may be preset and stored in the memory 120 and then transmitted. Here, the transmitted door registration code can be checked by the user through the application (APP) or text message of the communication terminal 2000, and the user who has confirmed this can input the door registration code into the application (APP). In this case, the application APP may transmit the input door registration code to the communication unit 30 .

The code authentication unit 140 authenticates the door registration code received by the communication unit 30 . The code authenticator 140 may determine whether the received door registration code is legitimate by comparing the transmitted door registration code with the received door registration code. As a result, since the code authenticator 140 authenticates a valid door registration code, the user's communication terminal 2000 and the smart door system 1000 may be linked with each other. In this state, the communication unit 30 receives a control signal from the communication terminal 2000 , and accordingly, the processor 40 may control the door lock unit 20 based on the control signal.

8 is a configuration diagram schematically illustrating a smart door system according to another embodiment of the present invention.

Referring to FIG. 8 , the smart door system 1000 according to another embodiment of the present invention may further include an ID retransmission request unit 150 and an ID authentication unit 160 .

Here, the user's ID input to the application (APP) is not stored in the central server, but is stored in the internal memory of the user's communication terminal 2000 . Since there is a possibility of leakage when user information is stored in the central server, in the present invention, as a means to increase security, a method in which the user's ID is directly stored in the communication terminal 2000 is adopted.

The ID retransmission request unit 150 generates an ID retransmission command requesting retransmission of the user's ID when the user's communication terminal 2000 approaches within a preset distance range while the door registration code is authenticated. In addition, the generated ID retransmission command is transmitted to the application (APP) through the communication unit 30 . The application (APP) receiving this may request the user by displaying the ID transmission command code corresponding to the ID retransmission command. In this case, the user may transmit the ID of the user stored in the user's communication terminal 2000 to the communication unit 30 by inputting the ID transmission command code into the application (APP). Here, the ID transmission command code does not necessarily have to be entered only in the form of numbers or letters, but it can be entered in the form of asking whether the application (APP) approves the ID retransmission command and tapping "Yes", "YES", etc. may be

When the user ID stored in the communication terminal 2000, that is, the retransmitted user ID, is received by the communication unit 30, the ID authentication unit 160 authenticates whether the received user ID is a valid ID. In this case, the ID authenticator 160 may compare the ID of the user pre-stored in the memory 120 with the ID of the retransmission user to determine whether the ID is a valid user ID.

In this way, in a state in which the user's ID is additionally authenticated, the processor 40 may operate according to a control signal transmitted from the user's communication terminal 2000 .

Meanwhile, in case the user loses the communication terminal 2000 linked to the smart door system 1000 , the user may input an emergency ID different from the user ID in the application APP. The input emergency ID is stored in the application (APP), and when connected to the application (APP) with the emergency ID, the connection between the user's communication terminal 2000 and the smart door system 1000 is performed through the application (APP). An interlocking blocking command to block may be transmitted to the communication unit 30 .

When the interworking blocking command is transmitted to the communication unit 30 , the processor 40 may block interworking between the user's terminal and the smart door system 1000 .

In addition, in the case of recovering the lost communication terminal 2000, the blocked interworking may be restored by accessing the application (APP) with an emergency ID and transmitting an interworking recovery command to the communication unit 30 .

The aforementioned intrusion contact unit 90 , fire contact unit 110 , door registration code transmission unit 130 , code verification unit 140 , ID retransmission request unit 150 , and ID verification unit 160 are each or at least Two or more may be integrated and implemented as hardware or software. That is, it may be implemented in the form of a digital or analog circuit located inside the door assembly 10 , or implemented as a separate chip or module and connected to the door assembly 10 , and the built-in memory 120 , a floppy disk, a compact disk, or a USB It may be implemented by storing and executing software in the external memory 120, such as. In addition, it may be implemented in a form that can be programmed by a user, and may be integrated into another built-in module (eg, the processor 40 ).
