That is, by capturing the monitoring area in front of the door by the photographing unit 130, it is possible to photograph a user who wants to open the door, as well as a person who does not have access qualification. Here, the person who does not have the above-mentioned access qualification means a person who causes a security risk, including an attempt to access, an attempt to obstruct shooting, and an attempt to damage the door robot 100.

In addition, the image photographed from the photographing unit 130 is determined by the controller 170 to be described later whether there is an image change, and if there is an image change, a process of detecting a face region is performed.

The authentication unit 140 performs authentication by using a face recognition algorithm, and compares the image of the face region detected in the image photographed by the photographing unit 130 with a plurality of authentication face images stored in advance. Authentication will be performed.

Here, an authentication DB for storing the above-described authentication face images may be further provided, and the above-described authentication DB may store the face image itself, and separately extract and store only characteristic information used for face recognition. Alternatively, both the face image itself and the feature information extracted therefrom may be stored. It should be noted that the "face image" used below is a concept that includes all of these.

When the normal authentication is completed from the authenticator 140, the controller 170 to be described later releases the locked state by controlling the lock of the door.

The shock detector 150 is for detecting an external shock applied to the door robot 100 and may be provided as a shock sensor, and may be set to operate under the control of the controller 170 to be described later or to operate at all times. have.

The door open detection unit 160 is for detecting whether the door is open, and may be provided as a sensor for detecting a contact state of the door or detecting whether the door is rotated, and the controller 170 to be described later is in the outing mode.

In this case, the control unit 170 may provide the user with information about the attempted damage of the door robot 100 by a person who does not have access qualification, and the user promptly reports to the outside or requests for security personnel. Allow action to be taken.

As another example, the controller 170 may open or close a door or switch to a security mode according to whether or not a password input from the key input unit 110 is matched after the authentication in the authentication unit 140 fails. When the shock is detected through the shock detector 150 after authentication fails in the authentication unit 140, the security mode is switched to the security mode.

That is, the controller 170 may provide a user with information about a situation in which an attempt is made to enter or damage the door robot 100 after inputting a password after failing self-authentication without access qualification.

When the controller 170 is set to the outgoing mode through a user input, when the door is detected to be opened from the door open detection unit 160 in a state where a normal authentication procedure is not performed, The evidence image may be transmitted to the user terminal.

Therefore, when a person without an entrance qualification enters the room through a window and exits through a door, information about the situation can be provided to the user, and an evidence image of the person who does not have the entrance qualification can be obtained.

On the other hand, the control unit 170 has an image change in the image photographed from the photographing unit 130, the face area is normally detected in the photographed image, the normal authentication process is performed through the authentication unit 140 If the authentication is completed, the door may be unlocked. In this case, when the security mode is set, the security mode may be released at the same time as the door is unlocked.

The communication unit 180 communicates with an external user terminal and performs a function of transmitting the evidence image and the security notification to the user terminal under the control of the controller 170. Here, the above-described user terminal may be any one of a smartphone, a tablet PC, and a personal computer that have been previously set or registered by the user.

In addition, the communication unit 180 may be implemented to communicate with the user terminal through various communication means including a mobile communication network and the Internet network.

On the other hand, the communication unit 180 receives a predetermined control signal from the user terminal and outputs it to the control unit 170, the control unit 170 performs a predetermined control operation corresponding to the control signal, thereby using the user terminal The remote control of the door robot 100 may be implemented.

The power supply unit 190 is supplied with the driving power of the door robot 100 by receiving the commercial power, and is provided to receive the commercial power through the power line embedded in the door and the room, and the commercial power is supplied to the key input unit ( 110, the display unit 120, the photographing unit 130, the authentication unit 140, the impact detecting unit 150, the door opening detecting unit 160, the control unit 170, and the communication unit ( 180 to supply the driving power.

In addition, the power supply unit 190 may be provided with a secondary battery that is charged when commercial power is applied and discharged when a power failure occurs to supply emergency driving power of the door robot 100.

When the power failure occurs, the power supply unit 190 detects the key input unit 110, the display unit 120, the photographing unit 130, the authentication unit 140, and the impact for a predetermined time. By supplying all the driving power of the unit 150, the door open detection unit 160, the control unit 170, and the communication unit 180, all functions including face recognition operate normally, but a predetermined time is When the power failure continues to elapse, the display unit 120 and the photographing unit 130 may be provided to operate in a power saving mode to cut off driving power of some devices.

Therefore, the door robot 100 according to an embodiment of the present invention, information and evidence data on security risks, including attempts to enter and exit by the person who does not have access qualifications, attempts to obstruct shooting and damage to the door robot 100. Not only does it provide a user, but also it can improve security performance by performing proper security operation.

Referring to Figure 3, it describes a security monitoring method performed in the door robot according to an embodiment of the present invention.

However, all functions performed in the security monitoring method shown in FIG. 3 are performed by the door robot described with reference to FIGS. 1 and 2, and thus, all functions described with reference to FIGS. 1 and 2 may be seen without explicit description. It should be noted that all functions performed in the security monitoring method according to the preferred embodiment of the present invention and described with reference to FIG. 3 are performed in the door robot according to the preferred embodiment of the present invention.

First, the photographing unit captures a predetermined monitoring area determined according to the installation position of the door robot (S110).

In this case, the photographing unit may photograph a predetermined photographing object existing in the surveillance area, for example, a user who wants to open the door or a person who does not have access qualification. Here, the person without the above-mentioned access qualification means a person who causes a security risk, including an attempt to access, an attempt to obstruct shooting, and an attempt to damage the door robot.

In addition, although the photographing unit may be set to operate only under a control of a controller when a specific time period or a specific condition is met, as the power unit is provided to supply driving power by using commercial power, the photographing unit is operated at all times to monitor the surveillance area. You can shoot.

Next, the control unit determines whether to set the go out mode (S120).

For example, a situation may occur in which there are no indoor occupants due to the user's outing. In this case, the user may set the outing mode through the key input unit. That is, the controller determines whether or not the outing mode is set by the user.

Next, when set to go out mode, the control unit detects whether the door is opened through the door open detection unit (S130).

At this time, the door open detection unit is provided as a sensor for detecting a contact state of the door or whether the door is rotated to detect whether the door is opened (S131), and the door is opened in a state where a normal authentication procedure is not performed. When the opening of the door is detected from the sensing unit, the control unit transmits a security notification to the user terminal and sets the image photographed from the photographing unit as an evidence image (S132).

After that, the photographing of the surveillance region can be resumed by the photographing unit.

On the other hand, while the opening of the door is not detected from the door open detection unit, the controller determines whether there is an image change in the image photographed from the photographing unit (S133), and if the image change is not detected, the door is opened. Will continue to monitor the process (S134).

However, when there is an image change in the image photographed by the photographing unit, step 151 to be described later may be performed.

On the other hand, even when the outgoing mode is not set by the user, the controller determines whether there is an image change in the image photographed from the photographing unit (S140).

In this case, the controller detects an external shock applied to the door robot through the shock detector. When the shock detector detects a shock in the state where there is no image change of the image captured by the photographing unit, the controller enters a preset security mode. It may be switched.

For reference, when the control unit is switched to the security mode, the first security operation for changing the currently set password to any number and transmitting the changed password to the user terminal, the second security operation for outputting a preset warning sound, the user At least one of the third security operation for transmitting the security notification to the terminal or the emergency contact network and the fourth security operation for transmitting the evidence image to the user terminal is performed.

Next, when there is an image change in the image photographed from the photographing unit, the controller detects the face area and opens and closes the door according to the authentication result of the authentication unit for the face area (S150).

In this case, when there is an image change in the image photographed by the photographing unit and a predetermined face region is detected (S151), the controller controls the authentication unit to compare the image of the face region with a plurality of authentication face images for authentication. After performing the operation (S152), if the normal authentication is completed in the authentication unit (S153), the door in the locked state is opened (S154).

On the other hand, if the authentication unit fails to perform normal authentication and the authentication fails, the control unit determines whether a password is input through the key input unit (S155), and if the password is input, it is determined whether the password matches the currently set password. It is determined whether or not (S156).

If the passwords match in step 156, the door is locked as in step 154. If the passwords do not match, the controller switches to the security mode as in step 163, which will be described later. .

In addition, when the authentication fails in the authentication unit and the password is not input in step 155, the controller may detect an external shock applied to the door robot through the impact detection unit (S157).

In this case, when the impact is applied to the door robot, the control unit is switched to the security mode, and if the impact is not applied to the door robot for a predetermined time, the photographing unit may resume shooting of the surveillance area.

Next, in the case where the image change is present but the face region is not detected in step 151 described above, the controller secures an evidence image and determines whether there is an external impact or an attempt to enter or exit the user. The security notification is transmitted to the terminal (S160).

In this case, the controller sets the image photographed from the photographing unit as an evidence image, and transmits the evidence image and the security notification to the user terminal by controlling the communication unit (S161), the external from the shock detection unit The controller detects whether a shock is detected and whether a password is input through the key input unit (S162). When the external shock is detected or a password is input, the control unit switches to the security mode (S163).

The controller, which has been switched to the security mode, performs a preset security operation. For example, after changing the currently set password to an arbitrary number (S164), the user terminal displays the evidence image and the security notification together with the changed password. Can be transmitted to (S165).

Next, the process is repeated again from the above-described step 110 until authentication is completed in the authentication unit or a password is correctly input through the key input unit.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
