Description

{Non-contact, non-face-to-face fire door integrated access control system}

The present invention relates to a non-contact, non-face-to-face access control system integrated into a fire door, and more specifically, to a new type of non-contact, non-face-to-face access control system integrated into a fire door, in which a frame, which is distinguished from the door frame by the edge of the fire door, is formed integrally with the fire door, a smart door lock connected to a home network and a fire door opening/closing means are installed inside the frame, and at the same time, an external power source is connected so that a stable power supply state can be maintained without the use of batteries, and the fire door can be opened and closed automatically or manually by the fire door opening/closing means, thereby improving user convenience and safety, and at the same time, the access control system can be installed through a simple process of installing a frame in which a fire door is formed and connecting it to a home network, and thus is easy to install and maintain.

Recently, the risk of buildings has increased due to the increase in height, depth, size, and use of various complexes, and the damage to life and property in case of fire is increasing. Therefore, it is necessary to strengthen the design and management of fire compartments to reduce the spread of fire and ensure evacuation safety. Among them, fire doors are essential facilities for preventing the spread of fire and for evacuation or passage.

In addition, the above fire doors are equipped with an access control system to control the entry and exit of visitors, and the above access control system generally uses a well-known digital door lock to control the entry and exit of individuals.

In addition, an RF card-type access control system is being used to control access to each department of a research institute or company by storing personal information on a card and allowing entry when certain information is entered into the code on the card.

However, access control systems using conventional digital door locks or RF cards are difficult to use when the door lock number is not remembered or the card with personal information entered is lost. In particular, in the case of RF cards, the card is easy to duplicate, making it unstable. In addition, conventional digital door locks have the problem that passwords can easily be leaked to others if the password is not changed frequently.

In particular, in the case of door locks installed in multi-family housing such as apartments, it is common for the installer to drill a hole in the fire door and install an access control system such as a door lock, but the installation location and installation form vary depending on the type of door lock, making installation very difficult. Furthermore, there is the inconvenience of having to separately link the installed door lock with the home network formed indoors, and there is a problem that the door lock and the home network are not compatible, making it impossible to use the home network.

In addition, in the case of door locks, there is a problem that it is very inconvenient and troublesome for the visitor to open the door lock by directly entering the password on the dial pad formed on the door lock or by contacting the RF card, and there is a problem that when the battery built into the door lock runs out, the door lock stops operating, making it difficult to enter and exit.

In addition, the fire door is opened and closed manually by the user, and the opening and closing process is assisted by the force of the door closer formed at the top, so it is performed manually, and a stopper is installed at the bottom to maintain the open state, so there are many inconveniences in opening and closing the fire door.

In order to solve the above problems, a fire door control device, as a conventionally known technology, is patented No. 10-2094605 (registration date: March 23, 2020), which is connected to a door closer installed on a fire door by a link to maintain the open state of the fire door in normal times and close the fire door in the event of a fire, wherein a main body is installed on the upper side of the frame of the fire door, a rotating body having an insertion groove on a peripheral surface is connected to a front end of a link and is rotatably installed within the main body, a rotating body locking insert inserted into the insertion groove of the rotating body is arranged to be movable in the radial direction of the rotating body within the main body, an insertion support member having a first inclined surface that supports the rotating body locking insert member is installed to be rotatably centered on the pin while moving linearly together with the pin within the main body, and a compression spring that supports the rear end of the insertion support member is installed within the main body to be positionally moved by an adjustment bolt, and at a position opposing the rotating body locking insert member. A support member supporting a first flat surface of an insertion support member is disposed within the main body, and a locking release member having a second inclined surface and a second flat surface is installed within the main body so as to be movable by a motor, such that the support member is supported by the second flat surface of the locking release member in normal times, and in case of a fire, the locking release member is moved by the motor and the support member comes into contact with and moves on the second inclined surface of the locking release member.

However, the control device for a fire door with the above configuration also has a structural limitation in that the actual opening and closing of the fire door is performed manually by the person entering, as it is a configuration that assists in the opening and closing of the fire door by linking with the door closer.

Patent Publication No. 10-2094605 (Registration Date: March 23, 2020) "Control Device for Fire Door"

The present invention is to solve the problems described above, and the purpose of the present invention is to provide a new type of non-contact, non-face-to-face integrated fire door access control system which forms a frame that is distinguished from the door frame by the edge of the fire door as an integral part with the fire door, and forms a smart door lock connected to a home network and a fire door opening/closing means by embedding them inside the frame to provide various functions, such as authenticating the face of an entrant using the smart door lock to open/close the fire door, or automatically opening and closing the fire door.

Another purpose of the present invention is to provide a non-contact, non-face-to-face access control system integrated with a fire door, which can be installed easily and quickly by installing a frame formed with a fire door integrally right after the door frame is formed in a building, thereby eliminating the need for separate processes such as installation of a door lock or connection to a home network, and which can also stably maintain a power supply state by connecting to an indoor constant power source to supply power.

Another object of the present invention is to provide a non-contact, non-face-to-face integrated access control system for a fire door, in which the fire door can be opened and closed automatically or manually, and when manually operated by a person entering or exiting, the fire door is kept open for a preset time by an administrator, and when the person entering or exiting manually rotates the fire door in the open state, the fire door automatically rotates and closes, so that the manual mode and the automatic mode operate organically to conveniently open and close the fire door.

The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

The purpose of the present invention described above is to provide a non-contact, non-face-to-face contact-free frame having an opening portion in which a fire door is rotatably received on the inside and a receiving groove and hole are formed on the upper portion, and a smart door lock is connected to a constant power source that is supplied through the hole on one side, a fire door opening/closing means having one side received in the receiving groove and the other side connected to the fire door to open or close the fire door by an electric signal of the smart door lock, and a fire door having a groove formed on the upper portion in which one side of the fire door opening/closing means is received in the receiving groove of the frame and the other side connected to the groove formed in the fire door so that the fire door opening/closing means is not exposed to the outside when the fire door is closed, and the smart door lock and the fire door opening/closing means are electrically connected inside the frame so that the fire door automatically opens and closes. This can be achieved by an integrated fire door access control system.

The above fire door opening/closing means is characterized by including a control unit that transmits and receives information with a smart door lock and controls the opening/closing operation of the fire door, a bolt rotation unit that is electrically connected to the control unit and controls the operation of a deadbolt and a latch bolt formed in a frame, a swing automatic opening/closing unit that is connected to the fire door and rotates in an automatic or manual mode to open and close it, an inner access sensor formed on an indoor space side of the swing automatic opening/closing unit to open and close the fire door when an insider goes out, and a finger-trapping prevention sensor to prevent fingers from being caught when the fire door is opened and closed.

The above-mentioned swing automatic opener is characterized by being divided into an open maintenance mode in which the fire door is maintained in an open state in manual mode, a manual closing mode in which the fire door is manually closed, and a fire door emergency stop mode.

The above open maintenance mode is when, when the fire door is closed, the user manually rotates it to the normal open position, and the drive motor formed inside the swing automatic opener operates to rotate the fire door to the stopper position, which is the fully open position, and the open state is maintained for a time preset by the manager, and when the preset time elapses, the drive motor operates to automatically close the fire door. The above manual closing mode is when, when the user manually wants to close the fire door while the fire door is open by the open maintenance mode of the fire door, the user pulls the opened fire door located at the stopper position and rotates it to the normal open position, and the drive motor formed inside the swing automatic opener operates to rotate the fire door to the normal closed position, and automatically closes the fire door. The above fire door emergency stop mode is when, when the swing automatic opener is automatically operated by the open operation signal of the smart door lock and the fire door is opened, and when the user pulls the fire door to forcibly close it, the detection sensor formed inside the swing automatic opener reverses the direction of the fire door. It is characterized by being modified to enable manual closing of the fire door by detecting the load and disconnecting the drive motor for 3 seconds, and at the same time as the fire door closes, the smart door lock transmits an operation signal to the bolt rotation part, so that the deadbolt and latch bolt quickly operate and quickly close the fire door.

As described above, the non-contact, non-face-to-face integrated fire door access control system according to the present invention forms a frame integrally with the fire door, which is distinguished from the door frame by the edge of the fire door, and installs a smart door lock connected to a home network and a fire door opening/closing means inside the frame to form them integrally, so that the frame in which the fire door is integrally formed is installed right when the door frame is formed in a building, so that a separate process such as installation of a door lock or connection to a home network is unnecessary, and thus the installation of the fire door can be easily and quickly performed. Furthermore, since the power supplied to the smart door lock and the fire door opening/closing means is connected to an indoor constant power source and used, there is an effect of stably maintaining the power supply status.

In particular, the smart door lock is activated when it recognizes the approach of a person, operates the facial recognition module, and when the person completes facial authentication, the fire door automatically opens and closes after a certain period of time, allowing the person to operate the fire door in a non-contact manner, thereby allowing the disabled and the elderly to enter and exit easily and safely.

In addition, the fire door can be opened and closed automatically or manually by the fire door opening and closing means, and when manually operated by a person entering, the door is kept open for a preset time by the manager, and when the person entering manually rotates the fire door in the open state, the fire door automatically rotates and closes, so that the manual mode and the automatic mode organically operate with each other, thereby providing the effect of convenient opening and closing of the fire door.

Furthermore, the above fire door opening/closing means can quickly close the fire door manually by stopping the automatic mode when a closing force is applied by an entrant during the process of opening the fire door. Therefore, when a woman or the elderly is in a dangerous situation, the fire door can be quickly closed and closed, allowing a quick response in an emergency situation.

In addition, the smart door lock installed in the above frame is installed in a form that is completely embedded in the interior of the frame, minimizing the portion protruding to the outside, thereby providing a simple aesthetic, while at the same time preventing attempts to damage the smart door lock from the outside for forced entry, thereby enhancing safety.

The present invention relates to a non-contact, non-face-to-face access control system integrated into a fire door, and more specifically, to a new type of non-contact, non-face-to-face access control system integrated into a fire door, in which a frame, which is distinguished from the door frame by the edge of the fire door, is formed integrally with the fire door, a smart door lock connected to a home network and a fire door opening/closing means are installed inside the frame, and at the same time, an external power source is connected so that a stable power supply state can be maintained without the use of batteries, and the fire door can be opened and closed automatically or manually by the fire door opening/closing means, thereby improving user convenience and safety, and at the same time, the access control system can be installed through a simple process of installing a frame in which a fire door is formed and connecting it to a home network, and thus is easy to install and maintain.

As described above, the non-contact, non-face-to-face fire door integrated access control system (100) according to the present invention is largely composed of a frame (30) in which a smart door lock (10) and a fire door opening/closing means (20) are formed, and a fire door (40) formed to be openable/closable on the frame (30).

The above frame (30) is installed by fitting its edge into a door frame (a) formed in a building, and has an opening (31) in which a fire door (40) is installed on the inside, a smart door lock (10) on one side, and a fire door opening/closing means (20) formed on the top.

In addition, the smart door lock (10) and the fire door opening/closing means (20) are electrically connected inside the frame (30) so that the fire door opening/closing means (20) operates in response to a signal from the smart door lock (10), and power for the smart door lock (10) and the fire door opening/closing means (20) is supplied through a power cable exposed through a hole (32) formed in the upper portion of the frame (30) and connected to the constant power of the building.

In addition, the fire door opening/closing means (20) can operate on its own by a sensor (not shown) formed inside.

The above smart door lock (10) is configured to include a detection sensor (11) for detecting an entrant approaching the fire door, a face recognition module including a camera (12) for recognizing the face of the entrant, a display (13) for providing notification information, and a deadbolt (14) and a latch bolt (15) fitted to the side of the fire door (40).

In addition, the smart door lock (10) is installed in a form that is completely embedded in the interior of the frame and minimizes the portion protruding to the outside, thereby providing a simple aesthetic while also preventing attempts to damage the smart door lock from the outside for forced entry.

Through the configuration of the smart door lock (10) configured as described above, the smart door lock (10) is activated by first detecting an entrant through the entrant detection sensor (11), and the camera (12) photographs the entrant's face to execute a facial recognition or facial authentication module, and when the entrant is authenticated through facial recognition, an opening signal is transmitted to the fire door opening/closing means (20) to automatically open the fire door for a certain period of time, and when the time has elapsed, the open fire door is immediately closed.

The above fire door opening/closing means (20) is formed with a control unit (21) that transmits and receives information from a smart door lock (10) and controls the opening/closing operation of the fire door (40), and the control unit (21) is configured to include a bolt rotation unit (22) that controls the operation of a dead bolt (14) and a latch bolt (15), a swing automatic opening/closing device (23) that automatically opens and closes the fire door (40) by rotating it, an inner access sensor (24) that is formed on the indoor space side and opens and closes the fire door when an insider goes out, and a hand-trapping prevention sensor (25) that prevents a hand from being caught when the fire door is opened or closed.

In addition, the fire door opening/closing means (20) is formed in a form in which one side is received in a receiving groove (33) of a frame (30) and the other side is connected to a groove (41) formed in a fire door (40), so that the fire door opening/closing means (20) is not exposed to the outside when the fire door is closed.

The above bolt rotation part (22) operates the deadbolt (14) and latch bolt (15) formed in the frame (30) in response to a fire door opening signal transmitted from the smart door lock (10) to transform the fire door (40) into a form that can be opened, and when a certain amount of time has passed and the fire door is closed, the deadbolt (14) and latch bolt (15) operate in response to a signal from the bolt rotation part (22) to close the fire door.

The above-mentioned automatic swing opener (23) is configured to control the opening and closing of a fire door (40), and is configured to transmit and receive signals from a smart door lock (10) and automatically open or close the fire door in response to an opening or closing signal transmitted from the smart door lock (10).

Furthermore, the above-mentioned automatic swing opener (23) is configured to control the opening and closing of the fire door semi-manually by the visitor separately from the operation signal of the smart door lock (10), so that the process of the visitor manually opening and closing the fire door can be made easier and more convenient, so that anyone, regardless of gender or age, can conveniently open or close the fire door.

Looking at the operation process by the manual mode of the above-described automatic swing opener (23), it can be divided into the open maintenance mode (a) in which the open state of the fire door is maintained, the manual closing mode (b) in which the fire door is manually closed, and the fire door emergency stop mode (c), as shown in Fig. 3.

The above fire door open maintenance mode (a) is such that when a person manually rotates a closed fire door to the normal open position (d), the drive motor (not shown) formed inside the swing automatic opener (23) operates to rotate the fire door to the stopper position (e), which is the fully open position, and the fire door is maintained in the open state for a time (10 to 300 seconds) preset by the manager. When the preset time elapses, the drive motor operates to automatically close the fire door.

In the above manual closing mode (b), when a person wants to manually close a fire door while the fire door is open in the open maintenance mode of the fire door, the person pulls the opened fire door located at the stopper position (e) and rotates it to the normal opening position (d), and then the driving motor (not shown) formed inside the swing automatic opener (23) operates to rotate the fire door to the normal closing position (f) and automatically close the fire door, making the closing process of the fire door easier and more convenient, so that anyone, regardless of age or gender, can conveniently close the fire door.

In the above fire door emergency stop mode (c), when the swing automatic opener (23) is automatically operated by the opening operation signal of the smart door lock (10) and the fire door is opened, if an entrant pulls the fire door to forcibly close it, a detection sensor (not shown) formed inside the swing automatic opener (23) detects a reverse load and disconnects the drive motor for 3 seconds, thereby transforming the fire door to be closed manually, and at the same time as the fire door is closed, the smart door lock (10) transmits an operation signal to the bolt rotation part (22), so that the dead bolt (14) and the latch bolt (15) quickly operate to close the fire door.

By configuring the fire door emergency stop mode (c) as described above, the fire door can be quickly closed when a woman or child enters, thereby fundamentally preventing the entry of an intruder who follows.

The above inner access sensor (24) is installed inside the swing automatic opener (23) and is formed in a form that detects in a downward direction to detect a person approaching the fire door from inside the room, and when the person tries to open the fire door to go outside, the inner access sensor (24) formed in the swing automatic opener (23) detects the approach of the person and operates the swing automatic opener (23) to open the fire door (40), so that the person can conveniently go out without touching the fire door, and after a certain period of time, it automatically closes to safely close the fire door.

In addition, even in a situation where the fire door is opened by the inner entrance sensor (24), if the automatic operation of the fire door is obstructed by a person going outside, the swing automatic opener (23) is switched to semi-manual mode so that the person going outside can quickly control the fire door.

The above hand-trapping prevention sensor (25) is configured as a built-in sensor that is installed inside the swing automatic opener (23) to detect the hinge installation position of the fire door, and is configured to prevent hand-trapping accidents by stopping the operation of the swing automatic opener (23) when the hand of an entrant is located at the hinge part.

As described above, the non-contact, non-face-to-face integrated fire door access control system according to the present invention forms a frame integrally with the fire door, which is distinguished from the door frame by the edge of the fire door, and installs a smart door lock connected to a home network and a fire door opening/closing means inside the frame to form them integrally, so that the frame in which the fire door is integrally formed is installed right when the door frame is formed in a building, so that a separate process such as installation of a door lock or connection to a home network is unnecessary, and thus installation of the fire door can be easily and quickly performed. Furthermore, there is a structural feature in that the power supplied to the smart door lock and the fire door opening/closing means can be used by connecting it to an indoor constant power source, so that the power supply status can be stably maintained.

In particular, the smart door lock is activated when it recognizes the approach of a person, operates the facial recognition module, and when the person completes facial authentication, the fire door automatically opens and closes after a certain period of time, allowing the person to operate the fire door in a non-contact manner, allowing even the disabled and the elderly to enter and exit easily and safely.

In addition, the fire door can be opened and closed automatically or manually, and when manually operated by a person entering, it remains open for a preset time set by the manager, and when the person entering manually rotates the fire door in the open state, the fire door automatically rotates and closes, so that the manual mode and automatic mode operate organically, and the fire door can be conveniently opened and closed.
