In addition, even when the visitor impacts the door, there is an advantage that the visitor's visit and the identity of the visitor can be easily confirmed.

In addition, when a visitor is expected to visit, it is easy to check the visitor every time the visitor visits, and to avoid the cumbersome process of allowing access.

In addition, the visual message and the hearing means can deliver the guide message to the visitor, there is an advantage that the visitor can easily recognize the content of the guide message.

Hereinafter, a security system and an operation method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the security system 10 according to the present invention is installed so that the visitor can operate the call unit 20 to notify the visit, the detection unit 30 for detecting the face information of the visitor, The output unit 40 for delivering the guide message to the visitor, the impact detection unit 50 for detecting the impact applied to the door, the opening and closing detection unit 60 for detecting the opening and closing of the door, detected by the detection unit 30 Storage unit 70, the transmission / reception unit 80 and the call unit 20, the detection unit 30, the output unit 40, the impact detection unit 50, the opening and closing detection unit 60, the face information is stored, It includes a control unit 90 for controlling the operation of the storage unit 70 and the transmission / reception unit 80, and determines whether to permit the access based on the identification of the visitor.

The calling unit 20 is used by the visitor to notify the visitor (hereinafter, 'user') of his visit, and includes a doorbell or knock means.

The detector 30 is provided to detect face (face) information of the visitor. In this case, the detector 30 may be installed at various places to reliably identify the visitor's identity and photograph the visitor at various angles. On the other hand, the present invention does not limit the type and function of the detection unit 30, and thus has the functions of a high-definition video camera CCTV, DVR, infrared CCD camera including visible light area, infrared camera measuring only pure infrared area, or general digital camera. Infrared cameras and the like can be used.

The output unit 40 is provided to deliver the guide message to the visitor, and includes a voice output unit 42 for outputting the guide message as a voice and a text output unit 44 for outputting the guide message as text.

The voice output unit 42 is provided as a speaker and outputs a guide message as a voice. Herein, the guide message refers to a message previously stored in the storage unit 70 and a message that the user speaks to the visitor when a specific condition is satisfied. In addition, the character output unit 44 outputs the guide message as a character.

For example, if the visitor is wearing a hat or mask and cannot identify the identity easily, the guide message such as "Please remove the hat (M1)" or "Please remove the mask (M2)" will be displayed. 42) can be provided as a voice and can provide a guide message such as M1, M2 as a text through the text output unit 44. As such, there is an advantage that the visitor can easily recognize the guide message by outputting the guide message through the visual means and the hearing means. Furthermore, the visitor who has lost the sense of sight or hearing can easily recognize the guide message when the visitor makes a visit.

Shock detection unit 50 is installed on the door and detects the impact applied to the door. In this case, the shock detection unit 50 may be a sensor such as a vibration sensor, a piezoelectric sensor.

 When an unidentified visitor attempts to open the door by applying an impact to the door without permission, the shock detection unit 50 detects an impact applied to the door and informs the controller 90 of the impact. The controller 90 outputs the guide message through the output unit 40. In this case, the guide message is used to identify the visitor's identity, such as "Please activate the caller", "The face was not recognized. Please shoot again", "Do not impact the door", This may include restraining the behavior that impacts.

And if the identity of the visitor is not detected even if the guide message is output or continuously impacts the door, an emergency signal is output through the output unit 40 to notify the surroundings of a dangerous situation.

Also, in general, the visitor operates or knocks the caller 20 to notify his visit, and knocking is more difficult for a user to recognize than to operate the caller 20. However, in the present invention, by installing the impact detection unit 50 on the door, the visitor is configured to operate as if the caller 20 was operated even if only knocking. This has the advantage that the user can easily recognize the visitor of the visitor.

The opening / closing detection unit 60 is installed in the frame 62 supporting the door and interlocks with the opening / closing unit 64 and the impact detecting unit 50 to open or close the door to detect whether the door is opened or closed and the visitor's visit. Specifically, when the visitor knocks on the door while the door is closed, the impact detection unit 50 detects the impact on the knock, and when the door detection unit 60 detects that the door is closed, the controller 90 By the control of the detection unit 30 detects the face information of the visitor or delivers the guide message stored in the storage unit 70 to the visitor through the output unit 40. Here, the guide message output through the output unit 40 may include, for example, "information of the call unit 20" and "information of visit" to inform the user of the visitor's visit. .

As described above, the opening and closing detecting unit 60 is interlocked with the opening and closing unit 64 and the impact detecting unit 50 so that the visitor attempts to open the door without permission of the caller 20 or only knocks. There is an advantage that can detect the face information and output the guide message to enable the visitor to operate the call unit 20 so that the user can easily know the visitor of the visitor.

On the other hand, when it is detected that the door can be easily opened in the opening and closing detection unit 60 (when the opening and closing portion 64 is not operated), the operation of the impact detection unit 50 is stopped. As such, the visitor scheduled to visit due to the interlocking of the impact detecting unit 50, the opening and closing detecting unit 60, and the opening and closing unit 64 may omit a series of procedures such as checking an identity and opening or closing a door.

The storage unit 70 stores face information of the visitor detected by the detector 30. In detail, the storage unit 70 may include a memory such as a ferroelectric random access memory (FRAM) or an electronically earable programmalbe read only memory (EEPROM), and the visitor's face information detected through the guide message and the detector 30. The visit time and facial information of an access permit, which will be described later, may be stored.

The transmitter / receiver 80 transmits visit information including the visitor's face information and visit time detected by the detector 30 to the management server 100 provided at a remote location, and receives information from the management server 100. do. As a result, the visitor's facial information and visit information can be managed remotely and used as evidence afterwards.

In addition, the transmitter / receiver 80 is linked with the wireless communication base station and the user's terminal to transmit 102 visit information, including visitor's face information and visit time, to the user's terminal. Thus, the user can cope with the visitor's visit.

The control unit 90 operates the call unit 20, the detection unit 30, the output unit 40, the shock detection unit 50, the open / close detection unit 60, the storage unit 70, and the transmission / reception unit 80. By controlling the security system 10 to operate correctly. Specifically, when the visitor notifies his visit by operating the caller 20, the controller 90 controls to detect face information of the visitor through the detector 30. If the visitor's face can be recognized based on the detected visitor's face information, the visitor's face information and visit time are stored in the storage unit 70 and the user is notified of the visit.

On the other hand, when it is difficult to recognize the visitor's face based on the detected visitor's face information, the output unit 40 transmits a guide message to the visitor to detect the recognizable face information. The guide message may include contents for accurately detecting the visitor's face, for example, "please remove the hat", "please remove the mask", "please see the front". As a result, the facial information of the recognizable visitor is detected, stored in the storage unit 70, and the user is notified of the visit.

As described above, by storing the face information and the visit time in the storage unit 70, it can be used as evidence afterwards, and there is an advantage of lowering the probability of criminal activity.

Here, a method of recognizing a face of a person from the detected face information, referring to FIGS. 3A and 3B, is a reference image (FIG. 3A) in which all parts of the face are exposed and an image of a visitor detected by the detector 30 (FIG. 3A). By comparing 3b), it can be determined based on the proportion of the unexposed parts and whether the eyes, nose, mouth and ears are recognized at the proper position of the face.

Meanwhile, the storage unit 70 stores facial information of an access permitter. Here, the permission of access means a person who can access from time to time, such as a family member or an employee. It is not necessary to have the access permit go through the access procedure provided in the security system 10 every time the access. Thus, the access information is stored in the storage unit 70 in the storage unit 70, and compares the visitor's face information detected through the detection unit 30 with the face information of the access licensor to omit the access procedure and permit access.

And if the visitor's face information and the licensor's face information is inconsistent, it is natural to go through the access procedure. This configuration has the advantage that the access permit can be easily accessed.

Meanwhile, referring to FIGS. 4 and 5, the method of operating the security system according to the present invention detects the visitor's visit by detecting the operation of the caller 20 (FIG. 4) and the shock acting on the door. To detect a visitor's visit (FIG. 5).

Referring to FIG. 4, in the method of detecting the visitor's visit by sensing the operation of the caller 20, the visitor detecting step S10 of detecting the operation of the caller 20 and the detector 30 operate by the visitor. Facial detection step (S12) for detecting facial information of the face, the facial information (face) is determined whether the detected human face information (S14) and the determination step (S16), it is determined whether the detected facial information can be recognized Comparing step (S24) for comparing the face information with the face information of the access permit.

When the visitor operates the caller 20 to notify his visit, it is determined whether the operation of the caller 20 is valid (S10). Here, if it is determined that the calling unit 20 is effectively operated, the detection unit 30 is operated. If it is determined that the calling unit 20 is not effectively operated, the valid calling unit 20 of the calling unit 20 is continuously performed. ) To detect the operation. The detector 30 is operated corresponding to the operation of the valid caller 20 to detect face information of the visitor (S12, face detection step). If it is determined that the detected face information is a face of a person (S14, facial judgment step), and if the detected face information is determined to be a face of a person, it is determined whether the recognized face can be recognized (S16, recognition judgment step). If the face of the person is not recognized based on the facial information detected in the face determination step (S14) and outputs a guide message through the output unit 40 (S18, output step) and performs the face detection step (S12). The guide message output in the output step S18 may include, for example, a content that requires re-shooting such as "The face was not recognized correctly. Please take another shot." When the face information detected in the recognition determination step S16 is human's face but is not recognized, the guide message is output through the output unit 40 (S18) and the face detection step S12 is performed.

On the other hand, if it is determined that the face information detected in the recognition judging step (S16) is recognizable, the detected face information is stored in the storage unit 70 (S20), and through the transmission / reception unit 80 to the management server 100 It transmits (S22). In operation S24, it is determined whether the detected face information matches the face information of the access permitter stored in the storage unit 70. If it is determined that the detected face information matches the face information of the access permitter, the visitor is allowed access (S26). If it is determined that the detected face information and the face information of the access permit is inconsistent, the user is notified of the visitor's visit to cope with it (S28).

Referring to FIG. 5, a method of detecting a visitor's visit by detecting an impact acting on the door may include detecting an impact acting on the door using the impact detector 50 (S100) and detecting a door opening and closing. (S102), detecting face information from the detection unit 30 (S104), determining whether the detected face information is a human face (S106), and determining whether it is recognizable (S108), and detecting the detected face information. Determining whether or not the face information of the access authorization is matched (S114), if a shock is detected in the door, and outputs a guide message (S120) and inducing the caller 20 to operate (S122).

The visitor knocks on the door to announce his visit. Then, the shock detection unit 50 installed in the door determines whether the shock acting on the door is a valid shock (S100, impact detection step). And check whether the door is opened or closed through the opening and closing detection unit 60 (S102, opening and closing judgment step). When the impact applied to the door is valid and the door is determined to be closed, the detector 30 is operated to detect the visitor's face information (S104, face information detection step). If it is determined in the opening and closing step (S102) that the door can be opened or opened, the subsequent process is terminated without performing.

After performing the facial information detecting step S104, it is determined whether the detected facial information is a face of a person (S106) and whether or not it can be recognized (S108). If it is determined that the detected face information is a face of a recognizable person, the detected face information is stored in the storage unit 70 (S110) and transmitted to the management server 100 through the transmitter / receiver 80 (S112). . In addition, it is determined whether the detected facial information coincides with the facial information of the access permission (S114). If it is determined that the detected facial information matches the facial information of the access permitter, the visitor is allowed access (S116). If it is determined that the detected face information does not match the face information of the accessor, the user is notified of the visitor's visit to cope with it (S118).

When it is determined that the facial information detected in the recognition determination step S108 is not recognizable, an emergency signal is output through the output unit 40 (S124).

On the other hand, when detecting the impact applied to the door in the impact detection step (S100), it is also possible to output the guide message through the output unit 40 (S120). In this case, the guide message may include a content for encouraging the visit to be informed by means other than knocking, for example, "Operate the calling part." Thus, when the visitor operates the caller 20 according to the guide message, the visitor 20 detects whether the caller 20 is effectively operated (S122). When the operation of the calling unit 20 is detected, the face information detection step S104 is performed. On the other hand, if the operation of the call unit 20 is not detected, the shock acting on the door is considered to be caused by someone other than the person and ends the operation of the security system 10.

According to the operation method of the security system as described above, there is an advantage that it is possible to know the visitor's visit and the identity of the visitor securely to deal with the visitor.

It also has the advantage of preventing the visitor from attempting to open the door without permission.
