DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing an example of the internal configuration of a security system according to an embodiment of the present invention. The security system 100 according to the present embodiment may include a human sensing unit 110, an input interface unit 120, and a door lock control unit 130.

The human detection unit 110 can detect a face of a person or a shape of a person using a camera and manage an image including a face of the detected person or a shape of a person. For example, the human sensing unit 110 receives an image through a camera using a CIS (CMOS Image Sensor) or a CCD (Charge Coupled Device), analyzes the inputted image, and detects a human face or a shape of a person And the image including the detected person's face or the shape of the person may be stored in a storage medium (not shown) that the person detection unit 110 may include or may further include the security system 100 have.

The input interface unit 120 can receive information from outside. For example, the input interface unit 120 receives a password through a number key, receives data included in an NFC (Near Field Communication) card, receives information, or recognizes a user's fingerprint, iris, vein, Input can be received. For example, the input interface unit 120 may be a number key, a card reader, or a sensor for recognizing at least one of a fingerprint, an iris, and a vein.

The control unit 130 may determine whether the door lock is opened or closed based on information input from the input interface unit 120 when a human face or a shape of a person is detected by the human detection unit 110. [

The door lock opening / closing unit 140 can unlock the door lock according to whether the door lock determined by the control unit 130 is opened or closed.

For example, even if correct information for opening the door is inputted through the input interface unit 120, the control unit 130 may lock the door lock if the face of the person or the shape of the person is not detected by the person detecting unit 110 It can be processed so as not to be released. Even if the thief has acquired a password or NFC card for releasing the door lock, the thief must detect the shape of the person or the face of the person in the person detecting unit 110 in order to open the door. In other words, in order to open the door with the password or the NFC card that the thief has acquired, the user must reflect his or her own image to the camera associated with the person detection unit 110. Even when a thief wears a mask, in recognizing a person's face, when recognizing the characteristics of the eyes, nose, mouth, etc., the face may not be recognized by wearing the mask. It is possible to restrict the acquired password and the NFC card to be unavailable to the acquired thief. Therefore, the state of the person who opens and closes the door lock can always be left as an image, so that the security of the door lock can be improved.

2 is a diagram illustrating an example of an internal configuration of a security system that further includes an output interface unit in an embodiment of the present invention. FIG. 2 shows an example in which the security system 100 described with reference to FIG. 1 further includes an output interface unit 210.

The output interface unit 210 can output data to the outside under the control of the control unit 130. [

For example, when the input of the information through the input interface unit 120 occurs but the shape of the person or the face of the person is not detected by the person detection unit 110, the control unit 130 controls the output interface unit 210, Can be controlled.

For example, the output interface unit 210 may output voice data requesting the viewer to come closer to the camera through a speaker, or output data such as text, image, and moving image requesting the viewer to approach the camera through the display.

As another example, the output interface unit 210 may sound an alarm through a speaker to inform the surroundings that a problem has occurred.

3 is a diagram illustrating an example of the internal configuration of a security system that further includes a network interface unit according to an embodiment of the present invention. FIG. 3 shows an example in which the security system 100 described with reference to FIG. 1 further includes a network interface unit 310.

The network interface unit 310 may transmit an image and / or an alarm to the user or the administrator 320 through a wired network or a wireless network under the control of the controller 130. [

For example, when the NFC card is read a predetermined number of times or more in a state in which an incorrect password is inputted a predetermined number of times or more through the input interface unit 120 or a face or shape of the user is not detected, The interface unit 310 can be controlled. At this time, the network interface unit 310 can transmit the image or the alarm to the user or the manager 320 through the wireless network or the wired network under the control of the control unit 130. For example, images and / or alarms may be transmitted to a management system or a manager's system of a security company, a smartphone, an e-mail, or a user's smartphone or e-mail.

2 and 3, the output interface unit 210 and the network interface unit 310 may be configured to sound an alarm according to control of the control unit 130 according to preset conditions, Or an alarm can be transmitted. For example, in addition to the conditions described in FIGS. 2 and 3, various predetermined conditions may include conditions in which a person is sensed for a predetermined time within a certain distance. If a person is detected within a predetermined distance for a predetermined time, the security system 100 sounds an alarm through the output interface unit 210 or transmits an image and / or an alarm through the network interface unit 310 To the user or manager 320. [ How to detect distances from people will be explained in more detail later.

4 to 7 are diagrams illustrating examples of a process of sensing a person in an embodiment of the present invention.

In the embodiment of FIG. 4, the human sensing unit 110 may include a camera 410 and may be used when a person's face or shape is sensed using the camera 410, or when someone touches the door lock And the input interface unit 120), the user detection unit 110 can capture the face or shape of the detected person and generate, store, and manage the image.

In the embodiment of FIG. 5, the human sensing unit 110 may include two cameras, a low resolution camera 510 and a high resolution camera 520. At this time, the human sensing unit 110 senses the face or shape of the user using the low resolution camera 610, captures an image using the high resolution camera 620 when a face or a shape is detected, Can be reduced. In the case of a door lock, since a battery is often used, when the human face or shape is continuously detected at a high resolution, the replacement cycle of the battery may be shortened due to a relatively large power consumption. In contrast, according to the embodiment of FIG. 5, by using the two cameras of the low-resolution camera 510 and the high-resolution camera 520 to share the sensing of the face or the shape and the shooting of the image, a high- .

On the other hand, if two cameras are used, the manufacturing cost of the security system 100 may increase. Accordingly, in the embodiment of FIG. 6, the human sensing unit 110 may include a resolution-changeable camera 510 capable of changing the resolution mode, such as low-resolution and high-resolution. At this time, the human sensing unit 110 continuously tries to detect the face or the shape of the user in the low resolution mode, and can shoot the image in the high resolution mode when the face or the shape is detected. Therefore, high-resolution images can be obtained while reducing battery consumption and manufacturing cost.

7, the human sensing unit 110 may include a sensor 710 and a camera 720. In the embodiment of FIG. The human sensing unit 110 may sense the approach of the object by using the sensor 710 first. For example, the sensor 710 may be one or more of various sensors capable of detecting the approach, distance, etc. of an object such as a depth sensor, an infrared sensor, a laser sensor, and the like. At this time, if the approach of the object is detected, the human sensing unit 110 can start sensing the face or the shape of the person using the camera 720, and can capture the image when the face or the shape is detected.

 Such a sensor 710 may be used to determine whether a person is located within a certain distance. Information on whether a person is located within a certain distance can also be obtained through the cameras described above. For example, techniques for measuring the distance to an object from an image input through cameras (e.g., a dual aperture method) may be used.

Alternatively, the image photographed by the person detection unit 110 may be used to determine whether the door lock is opened or closed. For example, it is possible to store information about a face of a person who has an access right, and to control the door to be automatically opened or closed when the person is recognized.

In this case, the input interface unit 120 of FIGS. 1 to 3 may be replaced with an image recognition unit (not shown) for comparing the previously stored face with the face recognized in the image.

In another embodiment, the human sensing unit 110 may perform a process of comparing the face stored in the image with the face recognized in the image. In this case, the control unit 130 controls the door lock / unlock unit 140 to open / close the door when the correct information for entering / exiting the door is input through the input interface unit 120 in a state in which the face of the person with access authorization is recognized can do. If a person whose face is not stored is inputting information through the input interface unit 120, the controller 130 may control the door lock opening / closing unit 140 to prevent the door from being opened even if the information is correct . In this case, the control unit 130 may sound an alarm using the output interface unit 210 or may transmit an image or an alarm to the user or the manager 320 using the network interface unit 310.

In another embodiment, the control unit 130 of the security system 100 may control the door lock / unlock unit 140 so as not to open the door when a specific person's face is detected, in order to prevent a specific person from entering or exiting. For example, in a door lock of an enterprise, the face of an employee can be stored and utilized. At this time, the controller 130 may control the door lock opening / closing unit 140 so that the door is not opened even if an accurate password is inputted to the exited employee.

FIG. 8 shows an example in which the security system 100 is controlled so that the illumination 710 of the entrance is turned on when the surroundings are dark, for example, at night, or when the object is approaching while the surroundings are dark. The illumination 710 may be implemented as an integral part included in the security system 100 or may be implemented as a separate component controlled through communication with the security system 100 in the case of smart illumination capable of wireless communication . For example, the lighting system 710 can detect the surrounding brightness or illumination and notify the security system 100 that the surroundings are dark, and the security system 100 can control the lighting system 710 to turn on . A sensor that detects the brightness or illumination of the surroundings may be included in the security system 100 so that the security system 100 may control the illumination 710 based on the output value of the sensor. The illumination 710 may emit light toward at least a part of the photographing range of the camera included in the human sensing unit 110. [
