First, a smart lock system using a user terminal according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

1 is a system configuration diagram illustrating a smart lock system using a user terminal according to an embodiment of the present invention.

As shown in FIG. 1, the smart locking system using a user terminal according to an embodiment of the present invention includes a user terminal 100, a management server 200, and a lock device 300.

The user terminal 100 executes a pre-installed application and transmits the unique number of the lock device input by the user and the password to be set to the management server 200.

At this time, the user terminal 100 may be a smart phone capable of short range communication such as Bluetooth, and may be a mobile smart key capable of unlocking the lock device 300 by executing an application installed in the smart phone . That is, the password of the lock device 300 can be set or the lock device 300 can be unlocked by inputting the set password.

At this time, the unique number of the lock device 300 is a unique identification number of the lock device 300 based on the location information, and the password is an arbitrary number that the user desires to set as a password.

The management server 200 sets the unlocking password of the lock device 300 corresponding to the unique number transmitted from the user terminal 100 to the password transmitted together with the corresponding unique number.

That is, the password input from the user terminal 100 is registered as the unlock password of the lock device 300.

At this time, the management server 200 may manage a plurality of lock devices 300 to which unique numbers are assigned.

More specifically, information including the position of the lock device 300, the lock and unlock operation may be accumulated and stored for each lock device 300, and the corresponding information may be periodically transmitted to the previously registered user terminal 100.

That is, the management server 200 transmits information on various activities occurring in the lock device 300 and the user terminal 100, for example, the number of the connected user terminal 100, the location information of the lock device 300, The time when the lock device 300 is opened using the user terminal 100, and the like can be managed and stored together.

1, the lock device 300 is not limited to the lock device 300. The lock device 300, which is fixed in position, such as a personal rental locker, a hotel door, a safe, etc., It may also be applied to the locking device 300 which is not fixed.

2 is a block diagram illustrating a lock device in a smart lock system using a user terminal according to an embodiment of the present invention.

When the password is input from the user terminal 100, the lock device 300 determines whether the input password matches the unlock password set by the management server 200, and unlocks the password according to the determination result.

Accordingly, the lock device 300 includes a communication unit 310 for receiving a password input from the user terminal 100 via short-range communication, a password input from the user terminal 100 and an unlock password An authentication unit 320 for authenticating the user according to the determination result, and a driver 330 for releasing the lock when authentication is completed.

In addition, when the lock device 300 releases the lock, the lock device 300 resets the lock release password set from the management server 200. [

More specifically, after the password for opening the lock device 300 is set from the user terminal 100, the lock device 300 confirms whether or not the password is matched with the lock release password set from the management server 200 To release the lock.

If another user terminal (not shown) is registered in the application of the user terminal 100, even if the password set by the user terminal 100 is inputted through another user terminal, Is released.

That is, since the lock device 300 can authenticate the password input from the user terminal 100 through the short-range communication with the user terminal 100, the owner of the lock device 300 can access the lock device 300 far away from the lock device 300 The lock device 300 may be released if the password entered by the owner of the lock device 300 by another person (another user terminal registered in the application) agrees with the lock release password have.

At this time, since the unlocking password is a concept of a disposable password that should be reset when the lock device 300 is unlocked and reset by the user terminal 100, exposing the unlocking password to another person has no effect on security.

Hereinafter, a smart unlocking method using a user terminal according to an embodiment of the present invention will be described with reference to FIG.

In step S340, the management server 200 sets the unlocking password of the lock device 300 corresponding to the unique number received from the user terminal 100 as the received password together with the unique number.

If the password is input from the user terminal 100 in step S350, the lock device 300 determines whether the password input in step S350 is identical to the unlock password set in step S340 in step S360.

More specifically, it is determined whether the password inputted in the step S350 and the unlocking password set in the step S340 are coincident with each other through the short distance communication.

If it is determined in step S360 that the password input in step S350 does not match the unlocking password set in step S340, the lock device 300 maintains the lock (S361).

At this time, the lock device 300 may output an alarm sound when the password input in step S350 is not equal to the unlock password set in step S340.

However, if it is determined in step S360 that the password input in step S350 is identical to the unlock password set in step S340, the lock device 300 releases the lock (step S370).

If the lock device 300 is unlocked in step S370, the unlock password set in step S340 is reset (S380).

In other words, since the unlocking password set in step S340 is a disposable password concept that is reset when the lock device 300 is unlocked and reset by the user terminal 100, even if the unlocking password is exposed to others, It does not affect.
