Description

Door lock apparatus using secret number and fingerprint}

The present invention relates to a door opening and closing device using a fingerprint recognition and password input, and more particularly to a door lock device using a password and fingerprint input to further improve the security by allowing the password input in parallel with the fingerprint recognition.

Recently, a door opening and closing device using a key operation, which is mainly used, has been designed to be so complicated and robust that it is almost impossible to open and close a door without a corresponding key, but it is easy to copy the corresponding key, so the stability of security is very low. there was.

In the case where a plurality of doors, such as an intelligent building, are to be managed, the keys are different for each door, and thus it is not easy to manage the keys. For example, when a manager or employee needed to look around several rooms for work, they had to carry all the keys for each door.

In addition, in addition to opening and closing the door, a personal identification card such as an ID (ID: Identifier) card may be used to record the user information in order to further secure security. If not, unauthorized persons other than the person could enter, and there was a fear of illegal use due to the lending of another person's ID card.

The conventional fingerprint recognition door opening and closing device includes a user authentication element using fingerprint information and a door lock element mounted on the door. Such a conventional door opening and closing device includes a fingerprint recognition sensor capable of detecting a person's fingerprint outside the door, a fingerprint storage unit storing the pattern by encoding a signal recognized by the fingerprint recognition sensor, and processing the recognized fingerprint pattern. Compared with the stored fingerprint pattern, the opening and closing control unit for controlling the opening and closing of the conventional door opening and closing device according to the result, and the opening and closing control unit is controlled by the opening and closing control unit.

However, in the case of the conventional door opening and closing device equipped with the fingerprint sensor on the door of the outdoor side as described above, the user authentication is impossible unless the fingerprint information is registered in advance, so that the person whose fingerprint information is registered is given to another person. Even if permission was granted, entry was not possible without the fingerprinted person accompanying him.

In addition, since the conventional door opening and closing device is exposed to the outside, fingerprint information regarding user authentication is easily intercepted by an outsider, and the problem that the fingerprint recognition sensor exposed to the outside is relatively easily contaminated or damaged still exists. It was. Therefore, when the door is opened and closed only by fingerprint recognition, there is a problem that a fingerprint recognition error occurs and access is impossible.

Therefore, the present invention has been devised to solve the above problems, by opening and closing the door by user authentication by fingerprint recognition, or by opening and closing the door using a password to utilize both advantages. To provide a door opening and closing device.

In the fingerprint registration, the password registration / delete button 95 is selected to select a registration mode, and the fingerprint registration mode is selected by pressing the '#' button on the keypad 30 of the outdoor unit for fingerprint registration. Then enter the registration address. If you press the '#' button after designating the number to be stored up to '01 ~ 50 'address, the fingerprint input module 40 is driven and the lamp of the fingerprint machine is turned on. If the fingerprint reader works, enter the fingerprint, and if it is off, remove the fingerprint. This iterates twice to prevent fingerprint input errors.

After inputting the registration address and inputting the fingerprint, the fingerprint recognition unit 50 recognizes the fingerprint based on a predetermined fingerprint recognition process, and the main controller 60 controls the fingerprint information to store the fingerprint information in the memory 61. The main control unit 60 determines whether the fingerprint recognized by the fingerprint recognition unit 50 is a duplicate registration, and if not, the fingerprint is read by the fingerprint recognition unit 50 by transmitting a registration command. Save the information to the fingerprint registration address and register it. If the cancel key is input during registration, the temporary information is deleted. If there is no minimum key input, the fingerprint information is stored in the memory and registered. It is preferable to register at least one or more plural fingerprints in order to reduce an error when only one finger is registered, and the registration number is 50 as an example, but it is further expanded by memory capacity and processor function. This is possible.

Fingerprint recognition uses image information of the fingerprint to identify the ridge, valley, ending point, bifurcation point, short ridge or island, and isolation of the fingerprint. or feature points such as lake and cross over, and the extracted fingerprint feature is used to identify whether the fingerprints are identical and to identify the unique binary code for each fingerprint. Fingerprint code) to be stored in a memory which is a fingerprint information storage means.

Such a technique of extracting a fingerprint image of a person and determining whether the same fingerprint is present is widely used. A technique of scanning a fingerprint as an image, analyzing a ridge vector of the fingerprint, and generating a unique code accordingly Enrollment and fingerprint verification.

As described above, the door lock device of the present invention can be used in the state of registering a password and a fingerprint. First, when the door is closed, the door open detection switch 91 detects the door closing, and the main controller 60 recognizes the door lock control. When the control unit 20 is controlled, the door lock control unit 20 drives the motor of the door lock device 10 to make a locked state. In other words, when the door is closed, the lock is automatically activated to lock. However, the automatic locking function can also be selected by pressing the function setting button to select the automatic locking mode and manual locking mode, which is to determine whether the main control unit 60 is an automatic locking mode or a manual locking mode to perform automatic control.

In addition, the indoor unit may be opened and closed by controlling the locking / unlocking of the door by using the door opening / locking internal switch 92. When the door is closed even in the manual mode is not automatically locked, when the door is forced to lock the external switch 93 in the outdoor, the main control unit 60 recognizes this to control the door lock control unit 20 to control the door lock.

In order to open the door outdoors, a password is input by pressing the number key of the keypad 30. When the main controller 60 presses the password input confirmation button, the controller recognizes the input password and compares it with the password registered in the memory 61, and if it matches, the door lock device 20 through the door lock controller 20. 10) to unlock the door. In this case, if the password is incorrect, the user inputs the password again and if the number of repetitions exceeds three times, the password input mode is controlled to not operate for a predetermined time. This is set by the program of the main control unit 60 and controlled.

If the finger is inserted into the fingerprint of the fingerprint input module 40, it is automatically recognized as the fingerprint input mode and scanned by receiving the fingerprint. The fingerprint recognition unit 50 analyzes the fingerprint information, and the main controller 60 When the registered fingerprint is compared with the registered fingerprint information and the input fingerprint information, the door is controlled to be opened. At this time, if a password or fingerprint input error occurs a predetermined number of times to prevent theft and anti-theft, all functions are set for a predetermined time to perform the anti-theft function.

Here, the password input and the fingerprint input can be determined by recognizing the automatically input state to distinguish the mode, but provided with a mode selection button on the keypad 30 to select either the password input mode or the fingerprint input mode. It can also be configured to be entered later.

Therefore, by using the door lock device of the present invention it is possible to open the door by selecting either the password input or fingerprint input.

Meanwhile, the lighting / alarm unit 70 generates a password registration / input, fingerprint input, door opening, door locking, and alarm upon forcible opening under the control of the main control unit 60, and the key of the keypad 30 Press any button for input to control the lighting on the keypad (30). Then, the melody sound is also stored in the memory 61 in various kinds, and after selecting the melody setting mode by key combination or the like, the melody is output so that the desired melody can be set.

On the other hand, the forced open alarm can be set by the user using the keypad 30, for example, press the "#" button, enter the password, and then press the "#" button again, the forced open alarm is set, forced open alarm When set, the alarm is automatically generated when the door is forcibly opened by other means except when the door lock is normally released by password input, fingerprint input, or the indoor open button. You must stop the alarm by entering.

The power supply unit 80 supplies external power to the operating power of the door lock device. The power supply unit 80 further includes a backup power supply unit 81 to operate the door lock device even during a power failure. The backup power supply 81 is configured to be charged by the power of the power supply 80 using a normal charging battery, and in case of power failure, the backup power supply 81 also discharges an external emergency power terminal ( Through 94), the battery can be connected to the power terminal from the outside to supply power.
