Description

Method, device, and system for controlling a door lock and opening / closing an entrance door using artificial intelligence

[0001] The present invention relates to a method, device, and system for controlling a door lock and opening and closing an entrance door using artificial intelligence. More specifically, it relates to a door lock device and system that detects an entrant by analyzing a detected door lock signal while the door lock device has learned the door lock signal, thereby enabling the door lock and the entrance door to be controlled.

[0002] Most electronic door locks and door opening / closing systems on the market are not compatible, causing inconvenience in use.

[0003] For example, standard door locks on the market used in private homes are specialized for opening and closing the locking mechanism and do not have the function to open or close the door itself. Furthermore, devices known as automatic door systems are not compatible with commercially available digital door locks, so most of them require a separate locking mechanism in addition to the simple opening and closing functions.

[0004] This involves the inconvenience of having to unlock the electronic door lock when opening or closing the door, and then opening or closing the door after unlocking it.

[0005] In this situation, when the hands are not free due to holding something or using a stroller, it not only causes inconvenience for the general public when entering or exiting the door, but also creates significant difficulties for the disabled and users of mobility aids in entering and exiting the home.

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

[0007] Furthermore, as the entrance door is a space that residents must pass through when entering or exiting their residence, the door lock is essential for opening and closing the door. Accordingly, since door locks can detect when a resident enters or exits, research is also being conducted on utilizing this information regarding resident entry and exit.

[0008] The present invention aims to solve the problems of the prior art as described above by learning a door lock signal while linked with a door lock and an entrance door, detecting the door lock signal, and opening and closing the entrance door based on this.

[0009] A method for controlling a door lock and opening / closing a door according to the present invention for achieving the above objective may include: a step of detecting a person approaching the door by a detection device around the door and generating a door lock unlock signal; a step of analyzing the door lock unlock signal using an artificial intelligence model based on the received door lock unlock signal; a step of generating door opening information according to the person in response to the analysis of the door lock unlock signal; a step of transmitting the door lock unlock signal to a door lock device; a step of transmitting a door opening signal including the door opening information to a door opening / closing device in response to the door lock device unlocking the door by the door lock unlock signal; and a step of opening the door differently according to the person in response to the door opening signal.

[0010] Here, the step of generating the door lock unlock signal may include detecting the person entering and exiting, extracting the characteristics of the person entering and exiting, and requesting the unlocking of the door lock and the information regarding the person entering and exiting.

[0011] In addition, the above visitor information may be information that classifies the visitor according to the pattern of movement or walking of the visitor.

[0012] Additionally, the form in which the above-mentioned entrant moves or walks may include a first entrant type in which the entrant walks together with other objects around the entrant, a second entrant type in which the entrant walks while being supported by a walking aid, and a third entrant type in which the entrant moves while riding on a walking aid.

[0013] In addition, the step of analyzing the door lock unlock signal using the artificial intelligence model described above involves applying the door lock unlock signal as an input variable and applying the visitor information and the door opening signal as output variables for learning, and analyzing the door lock unlock signal based on the learning.

[0014] In addition, the door opening information may be information for opening the door differently depending on the entrant, based on the pattern of movement or walking of the entrant.

[0015] Additionally, the door opening information may include door opening speed information, which is the speed at which the door opens according to the person entering, door opening angle information, which is the angle at which the door opens according to the person entering, and door opening maintenance time information, which is the time during which the door remains open according to the person entering.

[0016] In addition, the step of opening the door differently depending on the person entering may be such that, based on the door opening information, when the person entering is of the first type of person entering, the door is opened at a first speed, the door is opened at a first angle based on the closed state of the door, and the door is maintained open for the first holding time.

[0017] In addition, the step of opening the door differently depending on the person entering may be such that, based on the door opening information, when the person entering is of the second type of person entering, the door is opened at a second speed which is slower than the first speed, and based on the closed state of the door, the door is opened at a second angle which is smaller than the first angle, and the door is maintained open for a second maintenance time which is longer than the first maintenance time.

[0018] In addition, the step of opening the door differently depending on the person entering may be such that, when the person entering is of the third type, the door is opened at a third speed which is faster than the first speed based on the door opening information, and is opened at a third angle which is greater than the second angle based on the closed state of the door, and the door is maintained open for a third holding time which is shorter than the first holding time.

[0019] Additionally, the detection device detects the person approaching the door, determines whether the person is subject to an out-of-home restriction, and in response to the determination that the person is subject to an out-of-home restriction, when the person unlocks the door lock and opens the door, an alarm regarding the entry of the person subject to an out-of-home restriction can be performed.

[0020] In addition, the detection device may perform an alarm regarding the non-entry of the observed person through the door for a predetermined period in response to the observation of the observed person not being detected for a predetermined period.

[0021] In addition, the artificial intelligence model can receive a door lock status signal in response to the door lock device being locked or unlocked, analyze the door lock status signal, and transmit a door opening signal or a door closing signal regarding the opening or closing of the door to the door opening / closing device so that the door is opened or closed.

[0022] Meanwhile, a device for controlling a door lock and opening / closing a door according to the present invention for achieving the above objective may include: an information transmission / reception unit that receives and transmits a door lock unlocking signal and transmits a door opening signal; and a control unit that, based on the received door lock unlocking signal, analyzes the door lock unlocking signal using an artificial intelligence model, generates door opening information according to the person entering or exiting in response to the analysis of the door lock unlocking signal, transmits the door lock unlocking signal to a door lock device, and in response to the door lock device unlocking the door according to the door lock unlocking signal, transmits a door opening signal including the door opening information to a door opening / closing device, and controls the door to be opened differently according to the person entering or exiting.

[0023] Meanwhile, a system for controlling a door lock and opening / closing a door according to the present invention for achieving the above objective may include: a detection device that detects a person approaching the door near the door and generates a door lock unlock signal; a door lock device that maintains the door in a locked state or unlocks it; a door opening / closing device that opens / closes the door; and a control device that, based on the received door lock unlock signal, analyzes the door lock unlock signal using an artificial intelligence model, generates door opening information according to the person in response to the analysis of the door lock unlock signal, transmits the door lock unlock signal to the door lock device, and in response to the door lock device unlocking the door by the door lock unlock signal, transmits a door opening signal including the door opening information to the door opening / closing device, and controls the door to open differently according to the person.

[0024] A method, device, and system for controlling a door lock and opening and closing an entrance door using artificial intelligence according to the present invention has the following effects.

[0025] First, users can easily enter and exit the door. The door lock device and system utilizing artificial intelligence according to the present invention analyzes door lock signals using artificial intelligence, and accordingly, automatically unlocks the door lock and opens the door when an authenticated user approaches the door. Therefore, even users with physical disabilities can easily enter and exit the door.

[0026] Second, the status of entrants can be managed. The door lock device and system utilizing artificial intelligence according to the present invention can periodically detect whether an entrant residing in a residence is entering or exiting through the door. Accordingly, if an entrant does not enter or exit the door for a certain period, it is considered that an abnormal condition has occurred in the entrant, and this is notified to the control server that cares for the entrant, thereby enabling management to prevent abnormalities from occurring in the entrant. Furthermore, even if an entrant who should not leave the residence leaves the residence, this is notified to the control server that cares for the entrant, thereby enabling management to prevent abnormalities from occurring in the entrant.

[0027] Third, security can be enhanced. The door lock device and system utilizing artificial intelligence according to the present invention unlocks the door lock to open the door when an authenticated entrant approaches, and does not unlock the door lock when an unauthenticated entrant approaches. Therefore, since the door lock is unlocked only when an authenticated entrant enters, security can be enhanced by preventing entrants with malicious intent from entering.

[0055] Door Opening and Closing System

[0056] FIG. 1 is a block diagram of a door opening and closing system according to an embodiment of the present invention.

[0057] As illustrated in FIG. 1, the present invention may include a sensing device (100), a door lock device (200), a door opening / closing device (300), and a control device (400).

[0058] The detection device (100) is configured to detect a person approaching the door from inside or outside, generate a door lock locking signal or a door lock unlocking signal regarding the door lock, and transmit the generated door lock locking signal or door lock unlocking signal to the control device (400). At least one of these detection devices (100) may be installed on the door itself or on the upper left or upper right side around the door.

[0059] Here, the detection device (100) can be implemented as a motion detection sensor in addition to a module that captures video, such as a camera or CCTV (Closed-circuit Television). Accordingly, the detection device (100) can detect a person approaching the door by analyzing the captured video and detecting the motion of the person entering and exiting, generate a door lock unlocking signal requesting the door lock to be unlocked according to the detected person entering and exiting and transmit it to the control device, and transmit a door lock locking signal so that the door lock remains locked after the person enters and exits and the door is closed.

[0060] The door lock device (200) is configured to lock or unlock the door by receiving a lock signal or an unlock signal regarding the door lock and operating the door lock. When the door lock device (200) receives a door lock unlock signal, it can perform unlocking of the door lock to unlock the door, and when it receives a door lock signal, it can perform locking of the door lock for the door opening / closing device (300).

[0061] The door opening / closing device (300) is installed on the door and is configured to open and close the door so that a person can enter and exit the interior and exterior through the door installed at the entrance location. This door opening / closing device (300) can open the door to allow a person to enter and exit the interior and exterior by receiving a door opening signal from the control device (400), or close the door after a person has entered by receiving a door closing signal.

[0062] The door opening / closing device (300) is installed on the inside, outside, hinge, door frame, or wall of the door, and can open / close the door by calculating the material, weight, and wind pressure of the door and receiving a door opening / closing signal. At this time, the door opening / closing signal may be a signal including a door opening signal and a door closing signal.

[0063] Additionally, the door may be coupled with a power device or a switch including a motor on one side, and may be operated in a sliding or hinged manner by the power provided by the motor. Accordingly, the door opening / closing device (300) can control the motor to open / close the door in a sliding manner or in a hinged manner.

[0064] Here, the door opening / closing device (300) can detect whether an authenticated visitor has entered through the door based on an access sensor (not shown) installed on one side of the door after the door is opened, and transmit an access detection signal to the control device (400). Additionally, the access sensor can detect when the door is closed and transmit a door closing signal to the control device (400).

[0065] The control device (400) is connected to the detection device (100), the door lock device (200), and the door opening / closing device (300), and receives a door lock locking signal or a door lock unlocking signal, performs locking or unlocking of the door lock for the door, and controls the opening and closing of the door.

[0066] Additionally, the control device (400) may be implemented by being installed around the door lock device (200) at any part of the door, or it may be implemented by being connected to the door opening / closing device (300) and the door lock device (200) via a network at a location separate from the door. In this case, the connected network may be a wireless network such as Bluetooth.

[0067] Here, the control device (400) can learn door lock locking signals and door lock unlocking signals using an artificial intelligence model. That is, the control device (400) learns the door lock locking signals and door lock unlocking signals in advance, and, having learned the door lock locking signals and door lock unlocking signals, receives the door lock locking signal or door lock unlocking signal transmitted by the detection device (100) and can decide whether to transmit a control signal for locking the door lock or a control signal for unlocking it. In addition, when opening the door, it can decide whether the door opens differently depending on the person entering.

[0068] In addition, the control device (400) can control the door to be opened by receiving a signal from the door lock device (200) that the unlocking of the door lock is complete and transmitting a door opening signal to the door opening / closing device (300).

[0069] Additionally, when the control device (400) determines that a person has entered or exited through the door, it can transmit a door closing signal to the door opening / closing device (300) to control the door to be closed.

[0070] Additionally, if the control device (400) determines that the door is closed, it can transmit a door lock locking signal to the door lock device (200) to control the door lock to lock the door again.

[0071] Meanwhile, the control device (400) may be implemented as a chipset. Such a chipset may be implemented as a processor to perform operations on the received information. Accordingly, the control device (400) may be implemented integrally with the door lock device (200), or it may be located inside a casing in which the internal components of the door lock device (200) are installed.

[0072] Control Unit

[0073] FIG. 2 is a block diagram relating to a control device (400) in a door opening and closing system according to an embodiment of the present invention.

[0074] As illustrated in FIG. 2, in a door opening and closing system according to an embodiment of the present invention, the control device (400) may include an information transmission and reception unit (410), a control unit (420), and an alarm unit (430).

[0075] The information transmission and reception unit (410) is a component that receives information from external components of the control device (400). This information transmission and reception unit (410) can transmit and receive information or signals to the detection device (100), the door lock device (200), and the door opening and closing device (300). At this time, the information transmission and reception unit (410) can communicate with the detection device (100), the door lock device (200), and the door opening and closing device (300) using a Bluetooth method.

[0076] For example, the information transmission and reception unit (410) can receive a door lock unlock signal from the detection device (100).

[0077] Additionally, the information transmission and reception unit (410) can transmit a door lock unlock signal to the door lock device (200).

[0078] Additionally, the information transmission and reception unit (410) can receive a signal from the door lock device (200) that the unlocking of the door lock is complete, and can transmit a door opening signal to the door opening and closing device (300).

[0079] In addition, the information transmission and reception unit (410) can receive an entry detection signal in which an entry sensor installed on one side of the door detects whether a person has entered through the door.

[0080] Additionally, the information transmission and reception unit (410) can receive a door closure signal detected by the access sensor when the door is closed.

[0081] In addition, the information transmission and reception unit (410) can transmit a door lock lock signal to the door lock device (200).

[0082] The control unit (420) is configured to control locking or unlocking the door lock and to control the opening and closing of the door. This control unit (420) receives and analyzes a door lock unlocking signal from the detection device (100), and based on the analyzed door lock unlocking signal, transmits the door lock unlocking signal to the door lock device (200) to control the unlocking of the door lock on the door.

[0083] Additionally, the control unit (420) can control the door opening device (300) to open the door after the door lock is unlocked, thereby controlling the door to open differently depending on the person entering.

[0084] Additionally, the control unit (420) can receive and analyze a door lock lock signal when the door is closed, and transmit the door lock lock signal to the door lock device (200) based on the analyzed door lock lock signal so that the door lock is locked on the door.

[0085] Additionally, the control unit (420) can control the door to be opened by transmitting a door opening signal to the door opening / closing device (300) to open the door after the door lock is locked.

[0086] Here, the control unit (420) can learn to analyze the door lock unlock signal using an artificial intelligence model. At this time, the control unit (420) can learn by applying the door lock unlock signal as an input variable and applying the visitor information and door opening signal as output variables. Accordingly, the control unit (420) can learn to analyze the door lock unlock signal and output the visitor information and door opening signal.

[0087] At this time, the door opening signal may include information regarding the angle at which the door opens, information regarding the speed at which the door opens, and information regarding the duration for which the door remains open. Accordingly, the control unit (420) can control the door to open in response to the information of the person entering.

[0088] The alarm unit (430) is configured to transmit to the control server that an event has occurred when an event, such as an accident, occurs to an entrant near the entrance. This alarm unit (430) is implemented to include a speaker, a light-emitting element, etc., so that it can receive from the control unit (420) that an event has occurred to an entrant and transmit a signal to the control server, as well as transmit an alarm to an entrant near the entrance.

[0089] Here, an event may include a fall by a wheelchair user near an entrance, a fall by a cane user, a fall by a crutch user, a fall by a walking aid user, etc.

[0090] In addition, events may include situations where no entry is detected at the entrance for a certain period, or where a person with a condition such as dementia goes out through the entrance.

[0091] Here, the control server is a server used to monitor the status of visitors requiring management or care at a residence. Accordingly, the control server can provide the administrator managing the server with status information regarding whether each visitor requiring management or care has left the residence and when they entered or left the residence.

[0092] <Door Opening Process>

[0093] FIG. 3 is a flowchart showing the process of opening a door when a person enters or exits in a door opening and closing system according to an embodiment of the present invention.

[0094] As illustrated in FIG. 3, initially, around the door, a detection device (100) can detect a person approaching the door and generate a door lock unlock signal. <s300>This will be explained with reference to Fig. 4.

[0095] FIG. 4 is a diagram exemplarily illustrating the detection of a person approaching a door in a door opening and closing system according to an embodiment of the present invention.

[0096] As illustrated in FIG. 4, the detection device (100) allows a person to approach the door to enter or exit the building from inside or outside a specific building. Conversely, a person can approach the door to enter or exit the building.

[0097] Here, the detection device (100) can be implemented as a motion detection sensor in addition to a module that captures video, such as a camera or CCTV (Closed-circuit Television). Accordingly, the detection device (100) can capture the front of the door to obtain captured information and analyze the captured video. In addition, the motion detection sensor can help detect the motion of a person approaching the door and the cane, crutches, walking aid, wheelchair, etc. carried by the person. Such canes, crutches, walking aids, and wheelchairs can be referred to as walking aids.

[0098] At this time, the detection device (100) can determine whether the entrant is a person walking normally, a person with a disability, or a person with limited mobility by extracting characteristics of the entrant from the captured image and identifying them.

[0099] Specifically, the detection device (100) can learn to detect an entrant in a captured video. This learning may have a captured video containing an entrant as an input variable, and a captured video showing the entrant and the entrant's movement or walking pattern as an output variable. Accordingly, the detection device (100) can learn to identify an entrant and the entrant's walking pattern in the captured video.

[0100] For example, various people may be present in the recorded footage.

[0101] That is, a specific entrant may be a person without a disability who walks healthily on two legs, another entrant may be a person who sits in a wheelchair and moves around in a wheelchair, yet another entrant may be a person who walks with a cane or crutches, and yet another entrant may be a person who walks while pushing a walking aid.

[0102] Accordingly, the detection device (100) learns to detect an entrant in a captured video and to identify the walking pattern of the entrant, and can identify whether the entrant is moving in a wheelchair, walking normally, walking with crutches or a cane, or walking while pushing a walking aid in a video captured in front of the door. In addition, a motion detection sensor can assist in identifying whether the entrant is moving or walking.

[0103] Additionally, the detection device (100) can generate a door lock unlocking signal requesting that the door lock be unlocked after detecting an intruder and transmit it to the control device (400). At this time, the detection device (100) can generate a door lock unlocking signal requesting that the door lock be unlocked, including intruder information corresponding to the detected intruder.

[0104] That is, depending on the form in which the detected entrant moves or walks, the entrant may be moving in a wheelchair, walking normally, walking with crutches or a cane, or walking while pushing a walking aid, and the door lock unlock signal may be generated including the entrant information.

[0105] In this way, the generated door lock unlock signal can be transmitted to the control device (400).

[0106] Meanwhile, the detection device (100) can detect when an obstacle exists in front of the door and transmit this to the control device (400). That is, the detection device (100) can detect obstacles around the door in addition to the approaching person in the captured video. Accordingly, when the detection device (100) detects that an obstacle exists in front of the door, it transmits this to the control device (400), and the control device (400) can control the alarm unit (430) to perform an alarm to the control server or to the person approaching the door from the front, indicating that an obstacle exists in front of the door.

[0107] Meanwhile, the detection device (100) identifying the entrant may also include identifying an already registered entrant.

[0108] In other words, an entrant can proceed with an authentication process to be registered with the door opening and closing system. This authentication process can be carried out by accessing the app provided by the door opening and closing system through a terminal device carried by the entrant. At this time, the entrant registers visitor information including their name, photo, identification card, mobility aid, and specific details, and the door opening and closing system can register the entrant by performing the authentication process based on this visitor information.

[0109] Accordingly, the detection device (100) may detect an entrant in the captured image and identify whether the entrant is a registered entrant, and may include the identified entrant information in the door lock unlock signal and transmit it to the control device (400).

[0110] Additionally, when the detection device (100) identifies an entrant, it may register the entrant as a key entrant by including the characteristics of the extracted entrant according to the number of times the entrant is identified. That is, the detection device (100) detects this whenever an entrant enters or exits the door, and at this time, the detection device (100) can accumulate the number of times the entrant is identified. Accordingly, a threshold value regarding the number of times the entrant is set, and when the number of times the entrant is greater than or equal to the threshold value, the entrant is registered as a key entrant. Therefore, regarding key entrants, the control device (400) can pre-set and provide information such as door opening angle information, door opening speed information, and door opening duration information so as not to separately calculate information that matches the characteristics of the entrant.

[0111] Returning to Fig. 3, the door lock unlock signal can be analyzed using an artificial intelligence model based on the received door lock unlock signal. <s310>This will be explained with reference to Fig. 5.

[0112] FIG. 5 is a diagram exemplarily illustrating the analysis of a door lock unlocking signal in a door opening and closing system according to an embodiment of the present invention.

[0113] As illustrated in FIG. 5, the control device (400) can analyze the door lock unlock signal after receiving the door lock unlock signal from the detection device (100).

[0114] Specifically, the control device (400) can learn the door lock unlock signal in advance using an artificial intelligence model. That is, the control device (400) can learn by applying the door lock unlock signal as an input variable and applying the entrant information and door opening information as output variables. Accordingly, the control unit (420) can learn to analyze the door lock unlock signal and output the entrant information and door opening information.

[0115] Here, the visitor information may include whether the detected visitor is moving in a wheelchair, walking normally, walking with crutches or a cane, or walking while pushing a walking aid, depending on the form in which the visitor moves or walks.

[0116] In addition, the door opening information may include door opening angle information, door opening speed information, and door opening duration information.

[0117] Therefore, the control device (400) can analyze the door lock unlock signal based on the learning while having learned the door lock unlock signal in advance.

[0118] Next, you can generate door opening information. <s320>

[0119] Specifically, the control device (400) receives a door lock unlock signal and analyzes the door lock unlock signal to determine that the door lock should be unlocked and the door should be opened, and can also determine the person and the form of movement or walking of the person according to the person information.

[0120] Here, the control device (400) can determine whether the entrant and the form of movement or walking of the entrant are moving in a wheelchair, walking normally, walking with crutches or a cane, or walking while pushing a walking aid, based on the entrant information.

[0121] Accordingly, by determining the entrant and the pattern of movement or walking of the entrant, door opening information including door opening angle information, door opening speed information, and door opening duration information can be generated according to the entrant.

[0122] Next, a door lock unlock signal can be transmitted to the door lock device (200). <s330>This will be explained with reference to Fig. 6.

[0123] FIG. 6 is a diagram exemplarily showing the unlocking of a door lock in a door opening and closing system according to an embodiment of the present invention.

[0124] As illustrated in FIG. 6, the control device (400) determines that the door should be opened as a person approaches the door, and can transmit a door lock unlock signal to the door lock device (200) to unlock the door lock that is locking the door.

[0125] Additionally, the door lock device (200) can perform the task of unlocking the door lock that keeps the door locked after receiving a door lock unlocking signal from the control device (400), thereby unlocking the door lock.

[0126] Afterward, the door lock device (200) can transmit a signal to the control device (400) that the door lock has been unlocked after the unlocking of the door lock is completed.

[0127] In addition, in response to the door lock device (200) unlocking the door, a door opening signal according to the person entering can be transmitted to the door opening / closing device (300). <s340>This will be explained with reference to Fig. 7.

[0128] FIG. 7 is a diagram exemplarily showing the opening of a door after the door lock is unlocked in a door opening and closing system according to an embodiment of the present invention.

[0129] As illustrated in FIG. 7, the control device (400) can transmit a door opening signal to the door opening / closing device (300) after receiving a signal that the door lock has been unlocked.

[0130] Here, the door opening signal may include door opening information specific to the entrant, such as door opening angle information, door opening speed information, and door opening duration information. This is intended to allow the entrant to easily enter and exit the door based on the characteristics of the person approaching the door.

[0131] For example, a user may have a physical disability. In this case, the disabled person may be a user with a leg disability, that is, a person with a gait disorder. Here, a user with a leg disability may be a user who limps or moves using crutches due to a disability in one leg.

[0132] In addition, a person with a disability may be visually impaired. In this case, the visually impaired person may access the entrance with a guide dog.

[0133] In addition, a person with a disability may be a user of mobility aids such as a wheelchair. In other words, the user is approaching the doorway while riding a wheelchair.

[0134] In addition, the person entering the building may not be disabled but may have difficulty moving. That is, the person entering the building may be someone moving while pushing a walking aid or someone moving with a cane.

[0135] Therefore, the control device (400) needs to open the door differently depending on the person approaching the door. Accordingly, the control device (400) classifies the person into multiple types based on the characteristics of the detected person, and can apply door opening angle information, door opening speed information, and door opening maintenance time information differently based on the corresponding type.

[0136] In other words, the control device (400) classifies normal people, visually impaired people, people with limited mobility, people with disabilities riding in mobility aids, etc., and can control the door opening angle information, door opening speed information, and door opening maintenance time information differently according to the classified type of person entering.

[0137] In this case, a normal person refers to an entrant who does not have a separate disability, a visually impaired person refers to an entrant approaching the door with a guide dog, a person with mobility difficulties refers to an entrant who limps, moves with crutches, or moves while pushing a walking aid, and an entrant riding in a mobility aid refers to an entrant riding in a mobility aid such as an electric wheelchair or a manual wheelchair.

[0138] Finally, the door can be opened differently depending on the person entering. <s350>

[0139] For example, in the case of a visually impaired person, which is the first type of entrant, the control device (400) can control the door to open slowly at a first speed and close slowly. Additionally, since the visually impaired person and the guide dog may walk irregularly, such as forward and backward or diagonally, there must be sufficient space to the left and right. Accordingly, the control device (400) controls the door to open at a first angle between approximately 120 and 180 degrees, with the closed state of the door set to 0 degrees, and controls the door opening / closing device (300) to maintain the door open for a first maintenance time between approximately 10 and 15 seconds. Thus, the visually impaired person and the guide dog can sufficiently pass through the door.

[0140] In addition, in the case of a second type of visitor, a visitor with limited mobility, the control device (400) can control the door so that it opens at a second speed, which is slower than the first speed, and closes slowly. In addition, since a visitor with limited mobility walks steadily, for example using crutches, the door opening / closing device (300) can be controlled so that the door opens at a second angle, which is approximately between 90 and 100 degrees, and the door opening / closing device (300) can be controlled so that the door opening / closing time is a second holding time, which is approximately between 15 and 20 seconds. Accordingly, the door can be controlled so that a visitor with limited mobility can sufficiently pass through the door.

[0141] In addition, in the case of a third type of visitor, a visitor riding a mobility aid, the control device (400) can control the door so that it opens at a third speed faster than the first speed and closes quickly, thereby allowing the disabled person riding the mobility aid to pass through the door quickly and close it quickly. Also, because mobility aids such as wheelchairs are bulky, the control device (400) controls the door opening / closing device (300) so that the door opens at a third angle of approximately 180 degrees, and the door opening / closing device (300) can be controlled to maintain the door open time at a third maintenance time of approximately 5 to 10 seconds. Accordingly, the visitor riding the mobility aid can be controlled to pass through the door sufficiently.

[0142] Additionally, in the case of a fourth type of visitor, a visitor without a separate disability, the control device (400) can control the door to open at a fourth speed faster than the third speed and close quickly so that the visitor without a separate disability can pass through the door quickly and close it quickly. Additionally, the control device (400) can control the door opening / closing device (300) so that the door opens at a fourth angle of less than 90 degrees, and the door opening / closing device (300) can control the door opening / closing device (300) to a fourth holding time of less than 5 seconds. Accordingly, the visitor riding in a mobility aid can be controlled to pass through the door sufficiently.

[0143] Meanwhile, the detection device (100) can detect whether there is an object within the opening radius of the door when the door is opened and transmit this to the control device (400). That is, if the door is a hinged door, the opening of the hinged door can occur within a certain radius.

[0144] Therefore, if there is an object within the radius in which the door opens, an accident may occur in which the door collides with the object. Accordingly, the detection device (100) detects whether there is an object within the radius in which the door opens and transmits this to the control device (400), and the control device (400) controls the door opening / closing device (300) to temporarily stop the opening of the door when an object is present within the radius in which the door opens, and controls the alarm unit (430) to perform an alarm to the control server and the person entering.

[0145] Additionally, the detection device (100) can transmit to the control device (400) when a fall accident occurs in front of the door. For example, a person attempting to enter the door may be a visually impaired person, a person with limited mobility, a person using a wheelchair or cane, a person using a mobility aid, or a normal person, and a fall may occur to the person entering.

[0146] Accordingly, the detection device (100) can detect a fall accident occurring in front of the door in the captured video and transmit it to the control device (400). In addition, the control device (400) can control the alarm unit (430) to transmit the occurrence of a fall accident to the control server and transmit an alarm so that an administrator can take action.

[0147] Meanwhile, after a person enters or exits the door, the door opening / closing device (300) can close the door. This will be explained with reference to FIG. 8.

[0148] FIG. 8 is a diagram exemplarily showing the closing of a door after a person has entered or exited in a door opening and closing system according to an embodiment of the present invention.

[0149] As illustrated in FIG. 8, the control device (400) can control the door opening / closing device (300) to close the door when it is confirmed that a person has entered or exited through the door via the door opening / closing device (300).

[0150] Here, at least one sensor is installed on one side of the door, and the sensor can detect a person entering or exiting through the door and transmit the information to the door opening / closing device (300). Accordingly, the door opening / closing device (300) can transmit to the control device (400) that a person has entered or exited through the door via the entry / exit detection signal received from the sensor.

[0151] Additionally, the control device (400) receives an entry detection signal from the door opening / closing device (300), and if it determines that a person has entered or exited through the door, it can transmit a door closing signal to the door opening / closing device (300) to control the door to be closed. Accordingly, the door opening / closing device (300) can close the door and transmit a signal indicating that the closing of the door is complete to the control device (400).

[0152] In addition, when the control device (400) receives a signal that the closing of the door is completed, it can transmit a door lock locking signal to the door lock device (200) to control the door lock to perform locking on the door again. Accordingly, the door can be locked and closed by the door lock device (200).

[0153] Alternatively, in the case where no sensor is installed on the door, the control device (400) may control the door to automatically close after a predetermined time has elapsed since the door was opened.

[0154] Through this series of processes, the control device (400) detects a person approaching the door and, depending on the type of the detected person, controls the door lock device (200) and the door opening / closing device (300) to open the door so that the person can enter or exit the building.

[0155] Meanwhile, in the present invention, the control device (400) may receive a door lock status signal in response to the door lock device (200) being locked or unlocked by a user or by an external force, and may control the door to be opened by analyzing the door lock status signal.

[0156] Specifically, the door lock device (200) can provide API (Application Programming Interface) code or mechanical electronic and electrical signal information to the control device (400) in advance, and the control device (400) can control the opening and closing of the door by analyzing the door lock status signal while having learned the API code or mechanical electronic and electrical signal information in advance using an artificial intelligence model and transmitting a door opening signal or a door closing signal to the door opening and closing device (300).

[0157] For example, API codes or mechanical electronic and electrical signal information may be included in the door lock status signal. Such door lock status signals may be transmitted to the control device (400) when the door lock device (200) is locked or unlocked.

[0158] Accordingly, the control device (400) receives a door lock status signal in relation to whether the door lock device (200) is locked or unlocked, analyzes the door lock status signal to make a determination, and based on the determined door lock status signal, can transmit a door opening signal to open the door or a door closing signal to close the door to the door opening / closing device (300).

[0159] In addition, the door opening / closing device (300) that receives the door opening signal or door closing signal can open or close the door.

[0160] <Provide alarms regarding resident entry>

[0161] Below, we will explain how to provide an alarm regarding the entry and exit of residents with reference to the drawings.

[0162] FIG. 9 is a diagram exemplarily showing that when a resident who needs to be restricted from going out accesses the entrance door or leaves the residence through the entrance door in the entrance door opening / closing system according to an embodiment of the present invention, an alarm is provided.

[0163] As shown in FIG. 9, the control device (400) can perform an alarm to a control server or an interlocked user terminal when a resident who is a target of going-out restriction leaves the residence.

[0164] Specifically, among the residents, there may be a resident who is an important target of going-out restriction, such as a dementia patient. In the case of such a dementia patient, if the control by the protector is not temporarily applied, the patient may leave the residence through the entrance door and be exposed to a dangerous accident or become missing.

[0165] Therefore, in the present invention, among the residents, a target of going-out restriction can be registered to restrict the entry when a resident tries to enter or leave the entrance door, and if a resident opens the entrance door and leaves the residence, an alarm can be performed.

[0166] For example, the detection device (100) can extract the characteristics of the accesser who is a target of going-out restriction based on the photographed image of the accesser and transmit them to the control device (400), and the control device (400) can learn the characteristics of the accesser and register them as a target of going-out restriction and transmit them to the detection device (100).

[0167] After that, the detection device (100) detects an accesser approaching from the inside of the residence to the vicinity of the entrance door and transmits the accesser information to the control device (400), and the control device (400) can determine whether the accesser is an accesser who is a target of going-out restriction.

[0168] If the access control device (400) determines that an accesser approaching the vicinity of the entrance door is an accesser subject to an outbound restriction, it may not transmit a door lock release signal to the door lock device (200). In addition, it is possible to control the alarm unit (430) to output a guidance broadcast to the accesser approaching the vicinity of the entrance door to inform the accesser not to leave the residence.

[0169] If an accesser subject to an outbound restriction directly accesses the door lock device (200) to release the door lock, and leaves the residence after opening the entrance door, the control device (400) may control the alarm unit (430) to transmit information indicating that the accesser subject to the outbound restriction has left the residence to the control server or a user terminal connected to a protector who protects the accesser subject to the outbound restriction, thereby performing an alarm.

[0170] Therefore, in the present invention, it is possible to perform an alarm to notify that an accesser subject to an outbound restriction has left, so that an administrator who manages the control server or a protector of the accesser subject to the outbound restriction can take appropriate measures.

[0171] FIG. 10 is a diagram exemplarily showing that an alarm is provided when a resident has not entered or exited through an entrance door for a certain period of time in an entrance door opening / closing system according to an embodiment of the present invention.

[0172] As shown in FIG. 10, the control device (400) may perform an alarm to a control server or an associated user terminal when a resident, who is a main observation target, does not leave the residence for a certain period of time.

[0173] Specifically, a single-person household with a single elderly person or a mental illness such as depression may result in suicide. Accordingly, in the present invention, the corresponding resident may be designated as a main observation target to perform an alarm.

[0174] That is, the control device (400) can send an alarm to a control server or a user terminal connected to the guardian of the main observation subject to prevent solitary death if the main observation subject does not enter or exit through the door for a certain period of time.

[0175] For example, the detection device (100) can extract the characteristics of an entrant who is a primary observation target and transmit them to the control device (400), and the control device (400) can learn the characteristics of the entrant, register them as an object of restriction on going out, and transmit them to the detection device (100).

[0176] Afterward, the detection device (100) can transmit to the control device (400) that a person who is a primary observation target around the entrance / exit has not been detected for a certain period of time. At this time, the certain period of time can be set to 3 days.

[0177] Therefore, when the detection device (100) determines that the main observation target, the entrant, has not been detected for 3 days based on the last detected date, the detection device (100) can transmit an undetected signal regarding the main observation target, the entrant, to the control device (400).

[0178] Additionally, the control device (400) receives an undetected signal regarding a primary observation target visitor and determines that the primary observation target visitor has not entered or exited the residence for a certain period of time, and controls the alarm unit (430) to transmit to a control server or a user terminal connected to the guardian of the primary observation target visitor that the primary observation target visitor has not entered or exited the residence for a certain period of time, thereby performing an alarm.

[0179] Therefore, in the present invention, when a visitor who is a primary observation subject does not enter or leave the residence for a certain period, an alarm can be performed to notify the administrator managing the control server or the guardian of the visitor who is a primary observation subject so that appropriate measures can be taken.

[0180] The preferred embodiments of the present invention described above are disclosed for illustrative purposes only, 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.
