Hereinafter, a third embodiment will be described with reference to FIG.

Recently, due to the increasing interest in fingerprint recognition, various products are being released, and these products are being applied to many security systems.

Fingerprint recognition refers to checking the identity of the user by electronically reading the user's finger and comparing the data with the previously input data.

The basic structure of the fingerprint recognition module 86 of the fingerprint recognition door device 84 is largely composed of an input unit and an authentication unit. The input unit is in charge of a sensing function of photographing a fingerprint to be read. The user's fingerprint is checked to verify his / her identity.

The methods used to extract the individual features required for fingerprint recognition can be largely thinned, Fourier in the frequency space, wavelet transform, or neural network or fuzzy logic. Post-processing is required. In addition, syntactic, statistical, rule-based, and neural methods are used in combination, and there are some examples of the use of chain code and ridge tracking.

In general, as a general and reasonable method considering economics, an algorithm that extracts, stores, and compares the location and attributes of a feature point consisting of branching points, endpoints, and broken points of a fingerprint protrusion is adopted.

Fingerprint input using the principle of fingerprint recognition is currently using a semiconductor fingerprint input and an optical fingerprint input.

The semiconductor module can be miniaturized and inexpensive, making it suitable for miniaturization products such as mice and mobile phones, but due to the characteristics of the semiconductor, it is easily damaged by small pressure or shock, and the fingerprint is distorted. In addition, it is sensitive to temperature and humidity, static electricity, etc., and has low resistance to noise, such as being oxidized by physical contact or atmospheric factors.

In the case of the optical module, the fingerprint recognition rate is better than the semiconductor method, and it is generally widely used.

Among those using such a principle, the optical fingerprint recognition module 86 has good durability and is installed and used outdoors.

When the fingerprint recognition module 86 touches the fingerprint part of the finger in the normal mode, the image is acquired through the lens, and it is checked whether it matches the fingerprint stored in its own memory. If the user is not a user, no signal is applied to the door lock 14.

In addition, the operation principle of opening and closing the door in the normal mode using the remote control 10 and the operation principle due to the operation of the security mode selection switch (SW3) is the same as described in the first and second embodiments, detailed description thereof Omit.

Although the embodiments of the present invention have been described in detail as described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiments of the present invention.

As can be seen from the above description, according to the present invention, when a user opens or closes the door by an intruder or the like while going out, the user is immediately called to the outside to notify the unauthorized opening and closing, so that the user can cope immediately.

In addition, by applying to such a card key, a digital door lock, and a fingerprint recognition that does not use a traditional key, the door lock device as described above is secured firstly, and the security mode is secondly set by using a remote controller. It is almost impossible for unauthorized intruders to enter the room through more thorough crime prevention by informing them to the outside.

In addition, the door can be opened and closed using only the remote control, so it is very convenient even in the dark or blackout area, and it is possible to open and close the door regardless of the time when the power in the home is cut off. have.

In addition, it is very convenient because the elderly or disabled people who are uncomfortable with movement can be opened and closed only by operating the remote control without moving in the house.
