When the password is not the same, the controller 100 determines how many times have been exceeded by the preset data, and transmits through the speaker 171 that the password is different from the password set in the card 300.

If the passwords are different, the state of the door lock 1 is kept in a locked state while the speaker 171 is notified to the user who is indoors who is currently acting to open the door outside of the door.

When the act of opening the door outside the door is notified to the user in advance by an external motion sensor 181 installed outside the door.

And, the door lock (1) is to set the password, password input times, time of the door as described in the configuration, wherein the setting can be set through the button unit 120, the password, time, number of times, After the setting is completed, the data set through the button unit 120 is stored in the card 300 through the card 300 transmitting / receiving unit 111. The card 300 is installed in the door lock 1 to store the data. In the state close to the card receiving unit 110, select the setting button again so that the data can be stored in the card 300 wirelessly.

In addition, when a user passes through the door in which the door lock 1 of the present invention is installed, the control unit 100 reads the data through the card receiving unit 110 to determine how many users are currently outdoors and then the user In case of leaving, the controller 100 of the door lock 1 is currently abnormal even though the open switch (not shown) for separately opening the door is operated in addition to the data input through the card 300 or the button unit 120. It is assumed that the door is opened to prevent the locking device 190 from being released.

In other words, it recognizes that the current door is opened by using a separate release mechanism (not shown) through an inlet (not shown) through which a newspaper or milk is input, and keeps the door locked. When there is a user, the door lock is not released even when the open switch for opening is operated as described above, so that the user cannot go out. To prevent this, the user can install the button unit 120 at the indoor side. When the preset password is input through the button unit 120, the door lock 1 releases the locking device 190 to open the door, or operates the forced lock switching button 194a to force the locking of the door. Allow it to be released.

As described in the configuration, the door lock 1 continuously detects the voltage level of the battery 211 in a standby mode, that is, in a state in which it is not in use. ) So that the battery 211 may be completely consumed in the future, so that the state in which the lock state of the door lock 1 cannot be released can be coped with in advance.

The button unit 120 of the door lock 1 is a button so that the visually impaired can release the door lock 1 state by using the button unit 120 without losing the card 300 or using the card 300. Braille 123 is formed at 121 so that the visually impaired can open the door conveniently, and the braille 123 is formed in the same way as the button unit 120 installed in the room.

As described above, the power state of the battery 211 is continuously judged to eliminate difficulty due to power, and when the blind person opens the door to the keypad 120, the number of the button 121 is immediately changed. There is an advantage to open the door lock (1) smoothly so that you can see.

And, in the interior of the door by installing a fire sensor 165 in the event of a fire when the user is embarrassed to automatically open the door lock device 190 in preparation for not being able to open the door is damaged by the user And also there is an advantage that can not open the door through an abnormal method using a separate mechanism from the outside.

In the case of a password error, only a few times can be input to prevent a person other than the user from opening the door by using the button unit 120, and also, the door is opened for a certain time (the state that the lock is released) ), And detects it and keeps it locked again, thus preventing it from entering the room from the outside.

Looking at the effect of the digital door lock device according to the present invention, the method of opening and closing the locking device in a double configuration, and also in the opening and closing method of the card method, password input method and infrared method of the dual lock method, so that the user instead of the card Since it is close to the door lock while carrying it in a purse or a handbag, there is an advantage that the door can be easily opened and closed at a long distance.

In addition, since the key is digitalized into the data, it is impossible to duplicate the key when it is lost, and it is also effective to manage the key more efficiently.
