Description

Device for controlling the opening and closing of a door using artificial intelligence and a method for opening and closing a door

[0001] The present invention relates to a device and a method for controlling the opening and closing of a door using artificial intelligence, and more particularly, to a device, method and system for controlling a door lock and an automatic door, which detects a person approaching an automatic door based on artificial intelligence, identifies the person, determines whether the identified person is an authorized person, unlocks the door lock and opens the automatic door.

[0002] Most electronic door locks and door opening and closing systems on the market are not compatible, making them inconvenient to use.

[0003] For example, commercial door locks used in private homes are specialized for opening and closing the locking mechanism and lack the ability to open and close the door itself. Furthermore, devices called automatic door systems are not compatible with commercially available digital door locks, so most require a separate locking mechanism in addition to the simple door-opening function.

[0004] This requires a procedure to unlock the electronic door lock when opening or closing the door, and there is the inconvenience of having to open or close the door after unlocking it.

[0005] In this case, for the general public, it is not only inconvenient to enter and exit the door when their hands are not free due to reasons such as holding something in their hands or using a stroller, but it is also very difficult for the disabled and those using mobility aids to enter and exit the house.

[0006] Therefore, there is a need for a system that can analyze the signals of existing electronic door locks, recognize users, and automatically open and close the door.

[0007] The present invention is intended to solve the problems of the prior art as described above, and its purpose is to detect an entrant based on artificial intelligence while linked to a door lock and an entrance door, determine whether the entrant is an authenticated user, and unlock the door and automatically open and close the entrance door.

[0008] A method for controlling the opening and closing of a door according to the present invention for achieving the above object may include the steps of: receiving image information generated by a photographing device around the door; determining a user approaching the door based on the image information; transmitting a door lock unlock signal to a door lock device in response to determining that the user is an authenticated user; and transmitting a door opening signal to a door opening / closing device when the door lock device unlocks the door based on the door lock unlock signal.

[0009] Here, the step of determining a user approaching the entrance door may include detecting a user approaching the entrance door from the image information based on an artificial intelligence model, and determining whether the detected user is an authenticated user.

[0010] In addition, the step of determining a user approaching the door may include detecting a user approaching the door from the image information based on an artificial intelligence model, and determining a type of disability associated with the detected user based on the image information.

[0011] Additionally, based on the type of disability associated with the user, the door opening / closing device can be controlled so that the door opens / closes differently.

[0012] In addition, the above-mentioned disability type includes at least one disability type, and based on the user responding to the at least one disability type, the door opening / closing device can control the speed at which the door opens / closes differently.

[0013] In addition, the at least one obstacle type includes a first type to a third type, wherein the first type controls the door opening / closing device to open / close the door at a first speed, the second type controls the door opening / closing device to open the door slower than the first speed and close it slower than the first speed, and the third type controls the door opening / closing device to open the door faster than the first speed and close it faster than the first speed.

[0014] In addition, the at least one type of the obstacle includes a first type to a third type, wherein the first type controls the door opening / closing device to open the door at a first angle, the second type controls the door opening / closing device to open the door at a second angle greater than the first angle, and the third type controls the door opening / closing device to open the door at a third angle greater than the second angle.

[0015] Additionally, the above type of disability may include at least one of a visually impaired person, a disabled person riding a mobility aid, and a disabled person using crutches.

[0016] In addition, the state associated with the user includes a state in which both hands of the user are occupied with a specific object, and in response to determining from the image information that the user is in a state in which he or she cannot use his or her hands, the door lock device can be unlocked and the door opening / closing device can be controlled to open the door.

[0017] Additionally, the user authentication information may include at least one of biometric information, an authentication key, device authentication information, and an RFID signal associated with the user registered in the user terminal.

[0018] In addition, the step of transmitting a door opening signal to the door opening / closing device as the door lock device unlocks the door may further include transmitting a door opening signal to the door opening / closing device after receiving a signal from the door lock device that the door lock has been unlocked.

[0019] In addition, the method may further include transmitting a door closing signal to the door opening / closing device to close the door in response to detecting the user entering / exiting the door after the door is opened.

[0020] In addition, in response to detecting that the door is closed, the device may further include transmitting a door lock signal to the door lock device to lock the door.

[0021] Meanwhile, a device for controlling the opening and closing of a door according to the present invention for achieving the above object may include an information transmitting and receiving unit for receiving image information generated by a photographing device around the door; a user authentication unit for determining a user approaching the door based on the image information; and a control unit for transmitting a door lock unlock signal to a door lock device in response to determining that the user is an authenticated user, and transmitting a door opening signal to a door opening / closing device when the door lock device unlocks the door by the door lock unlock signal.

[0022] Meanwhile, a system for controlling the opening and closing of a door according to the present invention for achieving the above object may include: a photographing device positioned around the door to photograph a user approaching the door; a door opening and closing device connected to the door to open and close the door; a door lock device installed on one side of the door to lock or unlock the door; and a control device for receiving image information generated by the photographing device, determining a user approaching the door based on the image information, transmitting a door lock unlock signal to the door lock device in response to determining that the user is an authenticated user, and transmitting a door opening signal to the door opening and closing device when the door lock device unlocks the door in response to the door lock unlock signal.

[0023] The device for controlling the opening and closing of a door according to the present invention has the following effects.

[0024] First, users can easily enter and exit the door. The device for controlling the opening and closing of a door according to the present invention uses artificial intelligence to authenticate the user. When the authenticated user approaches the door, the door lock is automatically unlocked and the door is opened. Therefore, even users with physical disabilities can easily enter and exit the door.

[0025] Second, security can be enhanced. The device controlling the opening and closing of a door according to the present invention unlocks the door and opens it when an authenticated user approaches, but does not unlock the door when an unauthorized user approaches. Therefore, since the door lock is unlocked only when an authenticated user enters, it prevents entry by those with malicious intent, thereby enhancing security.

[0050] <System that controls the opening and closing of doors>

[0051] FIG. 1 is a block diagram of a system for controlling the opening and closing of a door according to an embodiment of the present invention.

[0052] As illustrated in Fig. 1, a system for controlling the opening and closing of a door may include a door opening and closing device (100), a photographing device (200), a door lock device (300), and a control device (400).

[0053] A door opening / closing device (100) is installed on a door and is configured to open / close the door, allowing users to enter / exit the building through the door installed at the building's entrance / exit location. This door opening / closing device (100) can open / close the door to allow authenticated users to enter / exit the building.

[0054] The door opening / closing device (100) is installed on the inside, outside, hinge, door frame or wall of the door, and can open / close the door by calculating the material and weight of the door and wind pressure and receiving a door opening / closing signal.

[0055] In addition, the door is equipped with a motor on one side, and can be opened and closed in a sliding manner or a swinging manner by the power provided by the motor. Accordingly, the door opening and closing device (100) can control the motor to open and close the door in a sliding manner or a swinging manner.

[0056] Here, the door opening / closing device (100) can detect whether an authenticated user has entered / exited the door based on an entry / exit sensor (not shown) installed on one side of the door after the door has been opened, and transmit an entry / exit detection signal to the control device (400). In addition, the sensor can detect when the door is closed and transmit a door closure signal to the control device (400).

[0057] The photographing device (200) is configured to photograph a user approaching a door to generate image information and transmit the generated image information to a control device (400). At least one of these photographing devices (200) may be installed on the door itself or on the upper left or upper right side of the periphery of the door.

[0058] The door lock device (300) is configured to lock or unlock a door. When the door lock device (300) determines that a user approaching the door is an authenticated user and receives an unlock signal for the door lock, the door lock for the door opening / closing device (100) is unlocked. When the door lock unlock signal for the door lock is not received, the door lock for the door opening / closing device (100) is not unlocked.

[0059] The control device (400) is configured to be connected to the door opening / closing device (100), the photographing device (200), and the door lock device (300), to determine a user approaching the door, unlock the door lock for the door accordingly, and control the opening of the door. The control device (400) may be implemented as an integral part of the door lock device (300), may be implemented as being installed around the door lock device (300) in any part of the door, or may be implemented as being connected to the door opening / closing device (200) and the door lock device (300) via a network in a location separate from the door.

[0060] In addition, the control device (400) can receive image information including a user approaching the door from the photographing device (200) and determine whether the user is an authenticated user from the received image information.

[0061] In addition, if the user included in the image information is an authenticated user, the control device (400) can control the door lock device (300) to release the door lock by transmitting an unlock signal for the door lock to keep the door locked.

[0062] In addition, the control device (400) can control the door to be opened by transmitting a door opening signal to the door opening / closing device (100) after receiving a signal from the door lock device (300) that the door lock has been unlocked.

[0063] In addition, if the control device (400) determines that an authenticated user has entered or exited through the door, it can control the door to be closed by transmitting a door closing signal to the door opening / closing device (100).

[0064] In addition, if the control device (400) determines that the door is closed, it can transmit a lock signal regarding the door lock to the door lock device (300) to control the door lock to lock the door again.

[0065] The control device (400) can register and store user information for authenticated users. Such user information can include the user's body, face, disability status, and characteristics.

[0066] <Control device configuration>

[0067] Hereinafter, a control device (400) that controls the opening and closing of a door and the locking and unlocking of a door lock will be described with reference to the drawing.

[0068] Figure 2 is a block diagram of a device for controlling the opening and closing of a door according to an embodiment of the present invention.

[0069] As illustrated in FIG. 2, a device for controlling the opening and closing of a door according to an embodiment of the present invention may include an information transmission and reception unit (410), a user authentication unit (420), and a control unit (430).

[0070] The information transmitter / receiver (410) is a component that receives information from external components of the control device (400). This information transmitter / receiver (410) can transmit and receive information to and from a door opening / closing device (100), a photographing device (200), a door lock device (300), etc.

[0071] For example, the information transmitter and receiver (410) can receive image information of the front of the door from the photographing device (200).

[0072] Additionally, the information transmitter / receiver (410) can transmit an unlock signal regarding the door lock to the door lock device (300).

[0073] In addition, the information transmitter / receiver (410) can receive a signal from the door lock device (300) indicating that the door lock has been unlocked, and can transmit a signal to open the door to the door opening / closing device (100).

[0074] In addition, the information transmission and reception unit (410) can receive an entry detection signal from an entry sensor installed on one side of the entrance door that detects whether an authenticated user has entered or exited.

[0075] Additionally, the information transmitter / receiver (410) can receive a door closure signal detected by a sensor when the door is closed.

[0076] The user authentication unit (420) identifies the user included in the video information and determines whether the user is authenticated. This user authentication unit (420) is implemented using artificial intelligence and can determine whether the user included in the video information is authenticated. This user authentication unit (420) can identify and determine the user from the video information based on accumulated data about the user.

[0077] The control unit (430) is configured to control the door to be opened based on whether the user approaching the door is an authenticated user. If the user authentication unit (420) determines that the user approaching the door is an authenticated user, the control unit (430) can control the door lock device (300) to unlock the door by transmitting an unlock signal for the door lock.

[0078] In addition, when the control unit (430) receives a signal from the door lock device (300) that the door lock has been unlocked, it can control the door to be opened by transmitting a door opening signal to the door opening / closing device (100).

[0079] In addition, when the control unit (430) confirms the entry and exit of an authenticated user through the door opening and closing device (100), it can control the door to be closed by transmitting a door closing signal to the door opening and closing device (100).

[0080] In addition, when the control unit (430) receives a signal that the door has been closed, it can transmit a door lock signal to the door lock device (300) to control the door lock to lock the door again.

[0081] <Method for controlling the opening and closing of doors>

[0082] Below, a method for controlling the opening and closing of a door will be described with reference to the drawing.

[0083] Figure 3 is a flowchart of a method for controlling the opening and closing of a door according to an embodiment of the present invention.

[0084] As illustrated in FIG. 3, a method for controlling the opening and closing of a door according to an embodiment of the present invention can initially receive image information generated by a photographing device (200) around the door. <s300>This will be explained with reference to Figure 4.

[0085] FIG. 4 is a drawing exemplarily showing detection of a person approaching a door in a device for controlling the opening and closing of a door according to an embodiment of the present invention.

[0086] As illustrated in Figure 4, a user or person can access a door inside or outside a specific building to enter the building. Conversely, a user or person can access a door to enter the building outside.

[0087] Here, a user may be a person who accesses a control device (400) connected via a terminal and approaches a door, and a person may refer to a person who accesses a door, regardless of whether or not the user is connected to the control device (400). In the present invention, a user may be interpreted as having the same meaning as a person, simply referring to a person passing through a door.

[0088] At this time, a photographing device (200) installed around the entrance door can photograph a user approaching the entrance door to generate image information and transmit the generated image information to the control device (400).

[0089] For example, a photographing device (200) may be installed near the top of the outer side of a door facing outside the building to photograph a user approaching from the front of the door and transmit the photographed image information to a control device (400).

[0090] In addition, a photographing device (200) can be installed near the top of the outer side of the entrance door in the direction of the inside of the building to photograph a user approaching from inside the building and transmit the photographed image information to the control device (400).

[0091] Such a shooting device (200) can be implemented with various shooting modules such as a camera or CCTV, and can be connected to a network to communicate with a control device (400).

[0092] Additionally, a user can access the control device (400) via an application on a terminal held by the user and transmit user authentication information to the connected application. This user authentication information may be transmitted together with the user authentication information registered on the user terminal when executing the application or signing up to use the application.

[0093] Returning to Figure 3, we can then determine which user is approaching the door based on the subsequent video information. <s310>This will be explained with reference to Figure 5.

[0094] FIG. 5 is a drawing exemplarily showing a device for controlling the opening and closing of an entrance door according to an embodiment of the present invention detecting a user and determining whether or not the user is an authenticated user.

[0095] As illustrated in FIG. 5, the control device (400) can detect and determine a user approaching the door based on image information captured by the photographing device (200). The control device (400) can detect a user from the image information and determine whether the detected user is an authenticated user.

[0096] Here, the control device (400) is implemented as an artificial intelligence model, and can detect a user from image information and determine whether the detected user is an authenticated user.

[0097] First, the artificial intelligence model can learn to detect users or people from image information by applying image information as input variables and users or people as output variables, and to determine whether the detected users or people are authenticated users.

[0098] For example, an AI model can learn to detect human appearances in a large number of photos, including those with different poses, races, ages, hairstyles, accessories, and whether the user is accompanied by a means of transportation.

[0099] As such, the technology for detecting people in image information is already well known, so a detailed description will be omitted.

[0100] At this time, the control device (400) can determine an authenticated user based on user information or user authentication information registered in the control device (400).

[0101] For example, a user can register biometric information, his / her own photo, information that can identify a user terminal or mobile device, a means with an embedded RFID tag, etc., in the control device (400).

[0102] Accordingly, the control device (400) can learn the appearance of the user based on a photo including the face, appearance, and appearance of the authenticated user, and determine whether the user is an authenticated user from the corresponding image information.

[0103] Alternatively, it may be possible to determine whether a user is authenticated by receiving a signal transmitted from a user terminal or mobile device carried by the user.

[0104] For example, a user can access the control device (400) through an application installed on a mobile device he or she possesses and request unlocking of the door lock and opening of the entrance door, and the control device (400) can determine whether the user is an authenticated user based on a signal received from the mobile device.

[0105] At this time, the signal received from the mobile device may be a signal containing biometric information such as iris, fingerprint, or face registered by the user on the mobile device and control device (400), or may be a signal transmitted from a device such as a smart door key or wireless remote control. This may be a known technology generally used when signing up for an application.

[0106] Additionally, the signal received from the mobile device may include authentication keys registered on the mobile device, device authentication information, etc.

[0107] In addition, if the user is disabled, it is possible to determine whether the user is an authenticated user by receiving an RFID signal generated from a disabled person registration card with an embedded RFID tag.

[0108] Alternatively, the control device (400) may be applied when performing a judgment to identify and authenticate a user by receiving information associated with an artificial intelligence algorithm from a cloud server rather than being implemented with an artificial intelligence model.

[0109] That is, user information associated with a user can be uploaded and stored on a cloud server. Accordingly, the control device (400) can receive user information from the cloud server and, based on the received user information, apply an artificial intelligence algorithm to determine whether the user is authenticated.

[0110] As such, the cloud server is a server related to hospital data, MyData, or public data. The control device (400) can be linked to the cloud server and obtain information about authenticated users from the cloud server. Accordingly, the control device (400) can determine whether a specific user has a disability or has specific physical characteristics.

[0111] Additionally, after the control device (400) authenticates a user, the authentication history may be automatically deleted. However, whether or not the user authentication history should be deleted may be applied as manual deletion rather than automatic deletion through the terminal owned by the user, and accordingly, the control device (400) may inquire of the user terminal as to whether or not the user authentication history should be deleted.

[0112] In addition, when the door lock device (300) is separated, damaged, or uses an entry / exit record, the control device (400) can control and display the speaker, display, etc. built into the door lock device (300), and notify the user or administrator through email, SNS, message, etc.

[0113] Returning to FIG. 3, in response to the user being determined to be an authenticated user, a door lock unlock signal can be transmitted to the door lock device (300). <s320>

[0114] Specifically, the control device (400) can transmit a door lock unlock signal to the door lock device (300) to unlock the door lock for the door to open the door if the user or person approaching from the front of the door is an authenticated user. Through this, the door lock device (300) can unlock the door lock that is being locked to close the door.

[0115] Here, the door lock device (300) can be installed on any part of the door. Accordingly, when the door lock device (300) is in a locking operation, it can connect the door and the wall of the building with at least one bar, and when the door lock device (300) is in an unlocking operation, it can disconnect the door and the wall of the building with at least one bar.

[0116] Returning to Figure 3 again, finally, by the door lock unlock signal, the door lock device (300) can unlock the door and transmit a door opening signal to the door opening / closing device (100). <s330>This will be explained with reference to Figure 6.

[0117] FIG. 6 is a drawing illustrating an example of a device for controlling the opening and closing of a door according to an embodiment of the present invention, determining an authenticated user, unlocking the door, and opening the door.

[0118] As illustrated in FIG. 6, the control device (400) can transmit a door lock unlock signal to the door lock device (300), and then, after receiving a signal from the door lock device (300) indicating that the door lock has been unlocked, transmit a door open signal to the door opening / closing device (100). Accordingly, the door can be opened, allowing an authenticated user to enter and exit the building through the door.

[0119] In addition, when the control device (400) confirms the entry and exit of a user authenticated through the door opening and closing device (100), the door opening and closing device (100) can transmit to the control device (400) that the user authenticated through the door has entered and exited.

[0120] Here, at least one sensor (not shown) is installed on one side of the door, and the sensor can detect an authenticated user entering or exiting through the door and transmit the signal to the door opening / closing device (100). Accordingly, the door opening / closing device (100) can transmit to the control device (400) that an authenticated user has passed through the door through a signal received from the sensor.

[0121] In addition, the control device (400) can control the door to be closed by transmitting a door closing signal to the door opening / closing device (100) after an authenticated user passes through the door from the door opening / closing device.

[0122] In addition, when the control device (400) receives a signal indicating that the door has been closed, it can transmit a door lock signal to the door lock device (300) to control the door lock to re-lock the door. Accordingly, the door can be closed and locked.

[0123] Alternatively, in a case where a sensor is not installed on the door, the control device (400) may control the door to automatically close after a preset period of time has elapsed after the door is opened.

[0124] Through a series of processes such as this, the control device (400) detects a user approaching the door, and controls the door lock device (300) and the door opening / closing device (100) depending on whether the detected user is an authenticated user, thereby opening the door only to authenticated users, allowing them to enter or exit the building.

[0125] <Door opening and closing speed control>

[0126] Below, the control device (400) can control the door to open when a disabled person is detected, as well as an authenticated user. This will be described with reference to FIG. 7.

[0127] FIG. 7 is a drawing exemplarily showing a device for controlling the opening and closing of a door according to an embodiment of the present invention, which detects a disabled person and controls the opening of the door.

[0128] As illustrated in FIG. 7, the control device (400) can control the door to be opened without a separate authentication procedure when the user approaching the door is disabled.

[0129] For example, a person with a disability may be someone with a leg problem, or someone with a walking disability. A person with a leg problem may have a problem with one leg, causing them to limp or use crutches to move around.

[0130] Accordingly, when the control device (400) detects that a user with a disability in his or her legs is approaching a door from the video information, it controls the door lock device (300) and the door opening / closing device (100) to open the door, thereby allowing the user with a disability in his or her legs to enter and exit the building.

[0131] Additionally, the person with a disability may be visually impaired. In this case, the visually impaired person may approach the door with a guide dog. Accordingly, when the control device (400) detects in the video information that the visually impaired person and the guide dog are approaching the door, it controls the door lock device (300) and the door opening / closing device (100) to open the door, thereby allowing the visually impaired person and the guide dog to enter the building.

[0132] Additionally, a person with a disability may be a user using a mobility aid, such as a wheelchair. That is, the user approaches the doorway in a wheelchair. Accordingly, when the control device (400) detects a user approaching the doorway in a wheelchair through video information, it controls the door lock device (300) and the door opening / closing device (100) to open the doorway, thereby allowing the visually impaired and their guide dog to enter the building.

[0133] Here, the control device (400) can control the angle and speed at which the door opens and closes differently depending on each type of obstacle.

[0134] Specifically, the control device (400) can classify a visually impaired person, a disabled person with leg problems, a disabled person riding a mobility aid, etc., and control the angle and speed at which the door opens and closes differently according to the classified disability type.

[0135] For example, in the case of a visually impaired person, the control device (400) can control the door to open slowly at a first speed and close slowly. Furthermore, since the visually impaired person and the guide dog may walk irregularly, such as forward, backward, or diagonally, there must be sufficient space left and right. Accordingly, the control device (400) can control the door opening / closing device (100) to open the door at a first angle of approximately 120 degrees, with 0 degrees as the reference when the door is closed. Therefore, the visually impaired person and the guide dog can sufficiently pass through the door.

[0136] Additionally, for a disabled person with leg limitations, the control device (400) can control the door to open and close at a second speed, which is slower than the first speed. Furthermore, for a disabled person with leg limitations who, for example, walks steadily with crutches, the door opening / closing device (100) can be controlled to open the door at a second angle of approximately 90 degrees. Accordingly, the control device can be used to ensure that a disabled person with leg limitations can sufficiently pass through the door.

[0137] In addition, in the case of a disabled person riding a mobility aid device such as a wheelchair, the control device (400) can control the door to open and close at a third speed faster than the first speed, so that the disabled person riding the mobility aid device can quickly pass through the door and then quickly close the door.

[0138] Additionally, since a mobility aid such as a wheelchair has a large surface area, the control device (400) can control the door opening / closing device (100) to open the door at a third angle of approximately 180 degrees.

[0139] In this way, the control device (400) can control the angle and speed at which the door opens and closes differently depending on the type of disability of the user included in the video information, thereby allowing the user to easily enter and exit the door.

[0140] Of course, the present invention also allows users to manually open the door. To this end, a button linked to a control device (400) may be provided on one side of the door. Therefore, an authenticated user or a person with a disability can press the button to unlock the door and open the door.

[0141] Meanwhile, in the present invention, if a person without a disability, as well as a person with a disability, is in an inconvenient state where they cannot use their hands, that is, if the user's two hands are occupied with a specific object and thus cannot open the door, the control device (400) can control the door lock to be unlocked and the door to be opened.

[0142] For example, a person who cannot use their hands may be a person pushing a stroller. Accordingly, the control device (400) may learn to detect a person pushing a stroller from image information, and upon detecting a person pushing a stroller from image information captured around the door, may transmit a door lock unlock signal to the door lock device (300) to unlock the door lock, and may transmit a door open signal to the door opening / closing device (100) to control the door to be opened.

[0143] In addition, a state in which a person cannot use his or her hands may be an image of a person holding a load in both hands. Accordingly, the control device (400) learns to detect a person holding a load in both hands from image information, and upon detecting a person holding a load in both hands from image information captured around the door, transmits a door lock unlock signal to the door lock device (300) to unlock the door lock, and transmits a door open signal to the door opening / closing device (100) to control the door to be opened.

[0144] In this way, if it is detected that not only a disabled person but also a person without a disability is in an inconvenient state where they cannot use their hands, the control device (400) can unlock the door lock and control the angle and speed of the door to open it, thereby allowing a person to easily enter and exit the door.

[0145] The above preferred embodiments of the present invention are disclosed for the purpose of illustration, and those skilled in the art with ordinary knowledge of the present invention will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the claims of the present invention.
