Security digital door lock with log data memory

The present invention relates to a secure digital door lock, and more particularly, a storage device to store an access record when opening a door using an access card, and to check the stored access record at an administrator terminal using an external memory. It relates to a secure digital door lock using.

The general door lock includes a latch bolt that protrudes and retracts toward the side of the door by operating a rotation means such as a lever. However, the latch bolt is a means for preventing the door from opening automatically, not a means for locking and releasing. In order to solve the instability of the latch bolt only, a mortise lock having a locking structure by the latch bolt and the dead bolt is installed and used by installing a dead bolt that is locked and released by a knob or grip. .

In addition, a digital door lock has been developed and used to release the dead bolt by pressing the key input button on the outside of the door or the interior button inside the door by the power of the motor. This digital door lock is convenient because the user can automatically move the dead bolt to the locked position by the power of the motor after the door is closed, even if the user forgets to lock the door. Of course, a digital door lock can also be inserted to unlock the dead bolt.

Even if the user does not have a key, the digital door lock can be unlocked through key input, and the demand is rapidly increasing as the recognition that the door is closed is automatically locked and safe and convenient.

However, the method of releasing the lock through key input has a problem that a third party who is not allowed to access may steal a key input by a person who is allowed to access and take a password and use it for impure purposes.

In addition, in companies with frequent entry and exit, employees can open the door using access cards with semiconductor chips in connection with security systems, and access records can be checked on the administrator's terminal and used as materials for time and attendance management and ERP. To make it work.

However, such a device is a kind of system rather than a door lock because not only means of recognizing the card and opening the door but also having a server for transmitting the access record to the administrator terminal via wired or wireless or notifying the security company of an abnormality. It requires a lot of installation costs.

The present invention has been made to solve the problems of the prior art as described above, when opening the door using the access card, stores the access record including the ID and access date and time of the access card, using an external memory It is an object of the present invention to provide a secure digital door lock using a storage device to check the access record stored in the door lock at the terminal of the administrator.

In addition, while allowing access by entering a password, even if a random number is entered, if there is a continuous password is included to provide a secure digital door lock using a storage device that allows access.

Security digital door lock using a storage device according to the present invention for achieving the above object, in the digital door lock that can be unlocked by using an access card having a unique ID, when the access card is close to the A card reader unit for reading an ID; An internal memory for storing access records; A memory slot into which an external memory can be inserted; And when it is determined that the ID of the access card read by the card reader is an allowed access, the motor drives the motor to unlock the dead bolt, and stores the access record including the ID of the access card. And a controller configured to copy (or move) the access record stored in the internal memory to the external memory when the external memory is inserted into the memory slot.

In this case, when the access record stored in the internal memory exceeds a predetermined number of records (or capacity), the controller deletes the access record first recorded first.

The apparatus may further include a key input unit for inputting a password outdoors. The controller may further include a pre-registered number when the number of digits greater than the number of digits of the previously registered password is input through the key input unit. When it is confirmed that a password is included, the dead bolt may be unlocked by driving the motor.

According to the secure digital door lock using a storage device according to the present invention, the door lock body allows access using the access card, but stores an access record including the ID and access date and time of the access card, and the stored access record is stored through an external memory. Since it can be copied and viewed on the administrator's PC, access records can be managed and security can be improved even without a separate security system.

Therefore, log data can be used for time and attendance management and ERP data in the company, and access control can be performed more precisely in the restricted area in the confidential library or group building, and data management is easy.

In addition, even if the accessor enters a random random number and enter a continuous password, by allowing the access to recognize the continuous password, there is no fear that the password is exposed to the third party when entering.

Hereinafter, the operation of the door lock according to the embodiment of the present invention will be described with reference to FIGS. 3 to 4. Prior to the description, the password allowing access and the IDs of the access card 130 are assumed to be registered in advance.

<Opening Door Using Access Card>

First, when the person brings the access card 130 to the card reader unit 80 of the outdoor unit, the card reader unit 80 reads the ID of the access card 130 (S405). Thereafter, the controller 90 checks whether the ID of the access card 130 read from the card reader unit 80 is an ID that allows access to the pre-registered <S410>.

If the control unit 90 confirms that the ID read from the card reader unit 80 is not a registered ID, the controller 90 generates a warning sound through a speaker (not shown). Restrict entry <S420>.

On the other hand, if the controller 90 confirms that the ID read from the card reader unit 80 is a registered ID, the controller allows the control unit 90 to drive the motor 100 to drive the dead bolt 20. ) To the inside of the indoor unit to open the door <S425>. Thus, a person can enter the room by opening an open door.

At this time, the controller 90 stores the access record including the ID read by the card reader 80 and the date and time when the card is read (or the date and time when the door is opened) in the internal memory 140.

After confirming that the door is closed through a sensor or the like, the control unit 90 drives the motor 100 in a reverse direction after a specific time so that the dead bolt 20 protrudes from the indoor unit so that the door is automatically locked.

<Door opening using password>

A person opens a slide cover 50 of the outdoor unit and inputs a password into the key input unit 70. Thereafter, the controller 90 checks whether the password input through the key input unit 70 is a previously registered password.

If the controller 90 confirms that the password inputted from the key input unit 70 is not a registered password, the controller 90 generates a warning sound through a speaker (not shown) and restricts access. Afterwards, the visitor may input the password again, but the controller 90 may stop the function for 20 seconds when it is confirmed that the password is incorrectly input three or more times.

On the other hand, if the controller 90 confirms that the password inputted from the key input unit 70 is a pre-registered password, the controller 90 may drive the motor 100 to unlock the dead bolt 20. .

In addition, the controller 90 stores the access record including the date and time when the door is opened through the password input in the internal memory 140.

The controller 90 may open the door by checking whether a pre-registered number is continuously input from a plurality of numbers input through the key input unit 70. That is, if the pre-registered access permission password is 4 digits of '1234', and the number input through the key input unit 70 is 15 digits of '198023123480098', the controller 90 continuously inputs 4 digit units. If it is confirmed that the pre-registered password '1234' is included, the door is opened. Therefore, even if a person enters a password through the key input unit 70 in conjunction with a third party, it is almost impossible for the third party to check what the password is among the 15-digit numbers, and furthermore, to memorize all the 15-digit numbers. Because it is more difficult, security can be further strengthened.

In this process, when access records are accumulated and stored in the internal memory 140, when the capacity of the internal memory 140 is exceeded, the controller 90 sequentially deletes the stored access records first.

For example, the controller 90 is configured to automatically delete the access record of 60 days from the access records stored in the internal memory 140, or to store only 150,000 access records in the internal memory 140, but more than that. When a record is generated, the first recorded record is deleted and then a newly generated record is stored, or only 1 gigabyte of the internal memory 140 is set to be used. After deleting the access record, the newly generated access record can be saved.

In this way, the access record stored in the internal memory 140 is copied (or moved) to the external memory 120 can be confirmed on the administrator's PC. That is, when the removable external memory 120 is inserted into the memory slot 110 of the door lock and a command is input through the key input unit 70, the controller 90 stores the access record stored in the internal memory 140. Copying (or moving) to 120, the external memory 120, which stores the access record in the form of a file, can be connected to the administrator's PC where a specific viewer is installed to retrieve the stored record.

Of course, the process of storing the access record in the external memory 120 is preferably performed in the state changed to the administrator mode by inputting a specific manager number to the key input unit 70.

Meanwhile, the external memory 120 and the memory slot 110 into which the external memory 120 may be inserted may be any type. In the drawing, the SD memory 120 is used as the external memory 120. As the slot 110, the SD memory slot 110 into which the SD memory 120 can be inserted is provided.

Preferred embodiments of the present invention described above are disclosed for the purpose of illustration, and those skilled in the art will be able to make various modifications, changes and additions within the spirit and scope of the present invention. And additions should be considered to be within the scope of the claims of the present invention.
