On the contrary, in the state in which the door 10 is closed, the state of the door 10 is kept on.

Security method using the fingerprint recognition security system according to an embodiment of the present invention having the above configuration will be described in detail.

1 to 4, the controller 440 receives visitor call information through the visitor recognition unit 200 (S10). That is, when the visitor presses the doorbell button 213 or knocks on the door 10, the detected information may be transmitted to the home server device 400 and may also be transmitted to the output device 300.

Then, the control unit 440 of the home server device 400 checks whether the preset mode is a facial recognition function (S11), and if not, automatically switches to the fingerprint recognition mode (S12).

According to the procedure of the switched fingerprint recognition mode, the control unit 440 first checks the fingerprint recognition through the external speaker 212, for example, after the visitor grasps the handle, and then directly opens the door using the handle. Please open the voice prompt message such as "Please open (S13).

When the visitor who receives the guide message catches the handle 130 of the door locking device 100, the contact sensor 150, that is, the piezoelectric sensor, may determine whether the visitor's hand is in contact with the fingerprint recognition unit 140. It becomes (S14). When the contact of the visitor is confirmed by the piezoelectric sensor, the fingerprint recognition unit 140 reads the body part of the contacted user to determine whether fingerprint recognition is possible (S15). When it is determined that the fingerprint is impossible, the fingerprint impossible information is transmitted to the controller 440, and the controller 440 outputs a voice guidance message once again. At this time, for example, if a user wears gloves, fingerprint recognition is not possible, so please remove the gloves and check the fingerprint recognition once again.

When it is determined that fingerprint recognition is possible in step S15, the recognized fingerprint recognition information is transmitted to the controller 440, and the controller 440 stores the recognized fingerprint recognition information in the storage unit 410 (S16). ). In addition, the control unit 440 transfers the fingerprint recognition information of the visited visitor to the integrated management server 500 so that it can be separately stored and managed in the remote integrated management server 500 (S17).

In addition, the controller 440 checks whether the recognized fingerprint information matches the fingerprint information of the visitable person (accessor) who is stored in the storage unit 410 (S18).

If it is determined in step (S18) that the match is determined, the control unit 440 transmits the access permission information to the door locking device 100 (S19). The locking coupling unit 120 of the door locking device 100 that has received the access permission information releases the locked state (S20). And preferably, the visitor may be able to output a guide message such as, for example, "because the access is allowed, please open the door using the handle" (S20).

Then, when the visitor receiving the guide message rotates by holding the handle 130, the door 10 is manually opened and closed, so that the visitor can open the door and enter the door (S22).

In this way, the stranger visits the door through the fingerprint recognition process, so that the user in the house does not need to open the door in order to identify the unidentified stranger. do. In the case of an acquaintance, the user may open the door directly, or operate the input unit 330 of the output device 300 without opening the fingerprint recognition mode or the face recognition mode, to open the door in the house.

On the other hand, if the fingerprint information recognized in the step (S18) does not match the accessor fingerprint information, the control unit 440 transmits the call information to the user, that is, the person in the house (S23). Here, the call information may be notified to the person in the household through the output device 300, or may be transmitted to the remote user terminal 720 through the wireless communication business base station 710. Therefore, if the visitor whose fingerprint has been identified is not a list of access permits, the user can report the follow-up actions, for example, through the door phone, or report the intruder to the management office or the police station.

In addition, when it is confirmed in the step S11 that the face recognition mode (function) is set, the control unit 440 controls to photograph the visitor through the camera 211 (S31).

The controller 440 determines whether facial recognition is possible by receiving the captured image information (S32). If it is determined that facial recognition is not possible, the controller 440 outputs a guide message to the visitor through the speaker 212 such as "Please remove the worn on the face and stare at the camera." It guides to maintain the posture and state that can be accurately photographed (S33).

When it is determined that facial recognition is possible through the captured image, the controller 440 stores the photographing information in the storage unit 410 (S34), and also transmits the photographing information to the remote integrated management server 500. It can be stored (S35).

Subsequently, the controller 440 compares / determines whether the received photographing information (face recognition information) matches the access permission information stored in the storage unit 410 (S36).

If the comparison result is matched, the above-described steps (S19, S20, S21, S22) are controlled to be performed. If the comparison result is not matched, call information is transmitted to the user (S23).

In the fingerprint recognition security system of the present invention as described above, the visitor is asked for fingerprint recognition, the visitor's fingerprint is recognized according to the request, and the recognized fingerprint is compared with the stored licensor information. Access can be granted, and visitors who are granted access can directly open the door by entering the door handle.
