First, the controller 50 of the mobile communication terminal 100 checks whether a beacon signal, which is a short range wireless communication signal, is received through the short range wireless communication unit 41 (S111).

When the beacon signal is received, the controller 50 determines whether it is a beacon signal received from the door lock apparatus 200 paired by the information included in the beacon signal (S113), and transmits the beacon signal received from the paired door lock apparatus 200 The door lock device 200 is requested to perform a synchronization operation and then performs a synchronization operation (S115) and determines whether the synchronization is successful (S117).

When the synchronization is successful, the controller 50 drives the ultra short-range wireless communication unit 42 to set the ultra short-range wireless communication mode (S119), and then checks whether the authentication information request signal is received from the door lock apparatus 200 (S121 ).

When the authentication information request signal is received, the control unit 50 notifies the display unit 20 of the receipt of the authentication information request signal, and receives an authentication information request signal for inquiring whether to accept the transmission of the authentication information for the authentication information request A notification message is displayed (S123).

After the authentication information request signal reception notification message is displayed, the control unit 50 determines whether the user accepts the authentication information transmission through the input unit 30 (S125). If the authentication information request signal reception notification message is accepted by the user, Or the identification information and the mobile communication terminal identification information to the door lock apparatus 200 (S127). The process of displaying the authentication information request signal reception notification message and determining whether to accept the authentication information transmission may be omitted.

After transmitting the authentication information, the control unit 50 checks whether the authentication result information is received from the door lock apparatus 200 (S129). When the authentication result information is received, the control unit 50 determines whether the authentication result is successful (S131).

If the authentication result is not successful, the control unit 50 notifies the authentication failure through the display unit 20 (S133) and, if the authentication is successful, notifies the door lock unlocking release (S135).

6 is a flowchart illustrating a door lock control method in the door lock apparatus of the door lock control system according to the present invention.

Referring to FIG. 6, the door lock control unit 140 of the door lock apparatus 200 periodically transmits a beacon signal when power is supplied (S211).

When the beacon signal starts to be transmitted, the door lock control unit 140 checks whether a synchronization request is generated from the mobile communication terminal 100 entering the synchronization area 1 (S213).

When the synchronization request is generated, the door lock control unit 140 determines whether the synchronization is successful (S217) after performing the synchronization operation with the mobile communication terminal 100 (S215).

If the synchronization is successful, the door lock control unit 140 drives the super short range wireless communication unit 122 to set the super short range wireless communication mode (S219), and then transmits an authentication information request signal to the mobile communication To the terminal 100 (S221).

The door lock control unit 140 determines whether authentication information, authentication information, and mobile communication terminal identification information are received from the mobile communication terminal 100 in response to the authentication information request (S223). If the authentication information is received, And performs secondary authentication according to whether or not the information is matched (S225).

After performing the secondary authentication, the door lock control unit 140 determines whether the secondary authentication is successful (S227).

If the secondary authentication fails, the door lock control unit 140 keeps the door in the locked state through the door lock / unlock unit 130 (S233), and notifies the door lock display unit 180 that the door is locked (S235 ).

On the other hand, if the secondary authentication is successful, the door lock control unit 140 controls the door lock / unlock unit 140 to release the lock of the door (S229), and then notifies the door lock display unit 180 that the door lock is released (S231).
