FIG. 1 and FIG. 2 are views for explaining the operation of the smart lock device according to an embodiment of the present invention.

The user terminal 100 is a terminal device having mobility and communication functions. When the user terminal 100 is located in a predetermined trigger area, the terminal device collects the location information according to the movement of the user and activates the smart lock device 300 And outputs a control signal to be controlled. At this time, the user terminal 100 may be any general purpose computing device such as a smart phone, a tablet PC, or the like, or may be a dedicated computing device for driving the smart lock device 300.

At this time, the trigger area is an area designated in advance through the user terminal 100 or an area set by a user in a personalized manner. Further, the trigger area may be set as a single area, or may be set as a plurality of areas.

According to one example, the trigger area can be set directly by the user utilizing the application and GPS coordinates installed in the user terminal.

According to another example, the trigger area is provided to the user terminal through a server (not shown) in the form of trigger area information, and the user can download the corresponding trigger area information through the installed application in the user terminal and indirectly set the corresponding area have.

The activation control signal transmitted from the user terminal 100 is transmitted to the smart lock device 300 via the network. At this time, a Public Switched Data Network (PSDN) may be used as the network. Further, the activation control signal is transmitted to the smart lock device 300 via the gateway 200 of the network including the smart lock device 300. The external computing device 50 is responsible for controlling the event area B. At this time, the smart lock device 300 and the gateway 200 may be connected through a short-range wireless communication module such as a wireless LAN or Bluetooth, or may be connected through a wired communication connection.

One or more smart locking devices 300 may be connected to the gateway 200. For example, the gateway 200 is installed in the gateway 200 in a co-residential building such as an apartment where a plurality of smart lock devices 300 are disposed, and the gateway 200 transmits an activation control signal to the smart lock device 300 .

Meanwhile, the gateway 200 includes a database in which the identifier information of the user terminal 100, the identifier information of the smart lock device 300, and the IP address information are matched. When the activation control signal including the identifier information of the user terminal 100 is received, the gateway 200 confirms the identifier information of the smart lock device 300 matched with the identifier information of the user terminal 100, And transmits an activation control signal to the device 200.

3 is a diagram illustrating a configuration of a user terminal according to an embodiment of the present invention.

A user terminal 100 according to an embodiment of the present invention includes a position location sensor 110, a memory 120, a processor 130 and a communication device 140. [

The position measurement sensor 110 collects position information of the user terminal 100 and updates the position information.

For example, the location location sensor 110 typically measures the coordinates of the user terminal 100 using a satellite of a GPS (Global Positioning System) via a chip embedded in the user terminal, and transmits the coordinates periodically or continuously To check whether the user terminal is located within the coordinates of the trigger area.

In addition, the position location sensor 110 may include a sensor or an element related to any technique capable of positioning the position of the user terminal via the user terminal 100 in addition to the GPS.

The communication device 140 performs wireless communication with the external computing device and transmits an activation control signal such as a security mode release signal or a security mode setting signal.

For example, the communication device 140 may transmit a security mode cancellation signal to the smart lock device 300 to cause the smart lock device 300 to release the security mode through wireless communication. In addition, the communication device 140 may transmit a security mode setting signal to the smart lock device 300, which sets the security mode of the smart lock device 300 through wireless communication.

At this time, the security mode release signal and the security mode setting signal may include the identification information of the user terminal 100. The security mode release signal and the security mode setting signal are transmitted to the gateway 200. The gateway 200 extracts identification information of the user terminal 100 included in the security mode release signal and the security mode setting signal, The smart lock device 300 that matches the security lock 100 is identified. At this time, the security mode release signal and the security mode setting signal can be classified according to the value of the specific bit string of the transmitted data.

The memory 120 stores a control program that controls the operation of the smart lock device. For example, the memory 110 refers to a non-volatile storage device that keeps stored information even when no power is supplied, or a volatile storage device that requires power to maintain stored information.

The control program stored in the memory 110 may be implemented in hardware, such as software or an FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

The processor 130 executes a control program that controls the operation of the smart lock device 300. [ The processor 130 determines, as the program is executed, whether the user terminal is located in at least one predetermined trigger area each time the location information is updated. If the user terminal is located within a specific trigger area, A security mode release signal of the smart lock device is transmitted. In addition, the user may perform a step of transmitting a security mode setting signal for setting a security mode of the smart lock device 300. [

4 is a view showing a configuration of a smart lock device according to an embodiment of the present invention.

The smart lock device 300 includes a locking device 310, a power management unit 320, a communication device 330, and a control unit 340.

The smart lock device 300 has two operation modes according to the setting of the user terminal 100, i.e., a normal mode and a secure mode. In the normal mode, the power management unit 320 continuously supplies power to the locking device 310, thereby causing the locking device 310 to perform a locking operation, a user authentication operation, or an unlocking operation. The power management unit 320 may be operated in a mode for switching to a low power mode and minimizing power consumption when the lock operation is maintained for a predetermined time or longer. In a low power mode, the user may activate a keypad, access a card or an RF chip The user is switched from the low power mode to the normal power use mode to perform the user authentication operation. That is, even in the low power mode, the user performs an operation of accessing the keypad, accessing the card or the RF chip, and continuously detecting the behavior of the user attempting fingerprint or iris recognition.

In the security mode, the power management unit 320 interrupts the power supply to the locking device 310 while the locking device 310 is kept in the locked state, thereby causing the locking device 310 to enter the dormant mode. In the idle mode, unlike the low power mode, the user does not perform the user identification operation even if there is the user's access to the keypad, the accessing of the card or the RF chip, or the user's attempt to fingerprint or iris recognition. As the security mode is released according to the activation control signal of the smart lock device transmitted from the user terminal 100 as the user terminal 100 is located in the specific trigger area, It is changed to the activated state. Such a security mode setting may be set in response to a security mode setting signal of the user terminal 100. [

The locking device 310 controls the physical locking state of the door through a user authentication procedure, and includes components such as a generally known digital door lock. For example, the locking device 310 is fixed to the door, and the first locking device (not shown) and the locking device 310, which are coupled to the frame of the door, are combined into a pair to perform the locking operation. To this end, the locking device 310 may include a driving motor, a second coupling mechanism that is driven by the driving motor and coupled to the first coupling mechanism to provide a locked condition. The locking device 310 may include a keypad for authenticating a user, a wireless user identification device using a card or an RF chip, and a user identification device using biometric information such as fingerprint recognition or iris recognition.

The power management unit 320 supplies power for driving the locking device 310. The power management unit 320 performs different operations according to the general mode and the security mode described above.

In the normal mode, the power management unit 320 continuously supplies power to the locking device 310, thereby causing the locking device 310 to perform a locking operation, a user authentication operation, or an unlocking operation. And when the lock operation is maintained for a predetermined time, it is switched to the low power mode to minimize power consumption.

In the security mode, the power management unit 320 interrupts the power supply to the locking device 310, thereby causing the locking device 310 to enter the resting mode. The security mode is released according to the activation control signal of the smart lock device transmitted from the user terminal 100 and the gateway 200 as the user terminal 100 is located in the specific trigger area, Lt; / RTI > As the security mode of the power management unit 320 is released, the operation mode of the lock device 310 is changed from the dormant mode to the active state.

The communication device 330 performs data communication with an external device, and receives an activation control signal from the public switched data network via the gateway 200, for example. The communication device 330 may be connected to the gateway 200 through wireless communication or wired communication.

The control unit 330 drives the power management unit to change the operation mode of the smart lock device 300. In particular, the control unit 330 controls the power management unit 320 according to the security mode setting signal received through the communication module, so that the smart lock device 300 operates in the security mode. That is, the power management unit 320 interrupts the power supply to the locking device 310, and the locking device 310 enters the resting mode. In addition, the control unit 330 controls the power management unit 320 according to the security mode release signal received through the communication module, so that the smart lock device 300 operates in the normal mode. That is, the power management unit 320 interrupts the power supply to the locking device 310, and the locking device 310 enters the resting mode.

5 is a flowchart illustrating a method of controlling a smart lock device of a user terminal according to an exemplary embodiment of the present invention.

The smart lock device control method according to an embodiment of the present invention includes collecting position information of a user terminal (S410), determining whether the user terminal is located within a trigger area (S420) And transmitting a security mode release signal when it is located at step S430.

First, the location information of the user terminal is collected through the location sensor of the user terminal 100 and updated (S410). For example, the location information can be updated periodically or continuously. Here, a typical position location sensor may be a GPS or a GNSS, and any position location sensor installed in a user terminal may be used.

Next, each time the location information is updated, the user terminal 100 determines whether the user terminal is located within a preset trigger area (S420). At this time, the trigger area may be set directly by the user through the input device of the user terminal 100. [ Alternatively, information about a trigger area previously designated through an external device may be transmitted to the user terminal 100.

For example, the user can set a trigger area through an application installed in the user terminal 100, and the user terminal 100 updates the position coordinates of the user terminal using the position location sensor, It can be judged whether or not it is included.

In another example, the user can download information about a pre-designated trigger area through an application installed in the user terminal 100, and can select a trigger area from a list of information about an indirectly provided trigger area, 100 can determine whether the user terminal 100 is included in the trigger area by updating the position coordinates of the user terminal 100 using the position location sensor.

Next, when the user terminal 100 is located within a specific trigger area, the security mode release signal of the smart lock device is transmitted through wireless communication (S430). At this time, the security mode cancellation signal changes the operation mode of the smart lock device 300 from the security mode to the normal mode. The secure mode release signal is transmitted to the gateway 200. The gateway 200 confirms the smart lock device 300 matching the identification information of the user terminal 100 included in the secure mode release signal, And transmits a secure mode release signal to the device 300.

Meanwhile, the security mode setting signal of the smart lock device 300 may further include a step in which the user terminal 100 transmits a security mode setting signal.

The security mode setting signal is transmitted to the gateway 200. The gateway 200 confirms the smart lock device 300 matching the identification information of the user terminal 100 included in the security mode setting signal, And transmits a security mode setting signal to the device 300.

6 is a flowchart illustrating a method of controlling a smart lock device according to an embodiment of the present invention.

6, a method of controlling a smart lock device 300 according to an exemplary embodiment of the present invention includes a step S610 of setting a smart lock device 300 to a secure mode, (S620), and changing the operation mode of the smart lock device (S620).

First, the smart lock device 300 is set to the security mode according to the security mode setting signal transmitted from the user terminal 100 (S610). It is also possible for the user to directly set the security mode through the setting function of the smart lock device 300 itself. Such a security mode may be set to one-time, or may be set at any time during a specific period. If the smart lock device 300 is set at a normal time, the security mode of the smart lock device 300 is released by the security mode release signal, and then the smart lock device 300 is unlocked The smart lock device 300 may again be set to the security mode within a predetermined time after the authentication.

For example, when the security mode is set to the always secure mode, the user transmits a security mode cancel signal to switch the smart lock device 30 into the normal mode, and after passing through the door through the user authentication process, 30) is again locked, and after a certain period of time, it switches back to the security mode. That is, after entering the residential space of an apartment or the like, the security mode is switched to the security mode, so that the outside person can not attempt to authenticate the user, thereby improving the security of the locking device.

Next, the security mode release signal for the smart lock device 300 is received from the user terminal 100 (S620). Accordingly, the smart lock device 300 performs a decryption and authentication procedure for the secure mode release signal. The control unit 340 of the smart lock device 300 collates the authentication key included in the security mode release signal with the authentication information stored in the control unit 340 to determine whether the security mode is the true security mode cancellation signal transmitted from the preset user terminal 100 . If the user terminal 100 is not authenticated, the security mode is not released.

When authentication of the security mode cancel signal is completed, the operation mode of the smart lock device is changed from the security mode to the normal mode (S630). To this end, the control unit 340 drives the power management unit 330 of the smart lock device to switch the smart lock device 300 to the normal mode. As the power management unit 330 is driven, the lock device 310 of the smart lock device 300 is switched to the normal mode, and the user authentication procedure and the like can be performed.
