DETAILED DESCRIPTION OF THE INVENTION

[0008] This embodiment discloses the following features. The first feature is that the fitting device is provided with an opening / closing body that performs a closing operation, and is configured to detect the occurrence of a closing failure of the opening / closing body and notify the occurrence of the closing failure (see Figs. 1 to 7).

[0009] As a second feature, the device is provided with an open recognition means for determining whether the opening / closing body is in an open state, and when the open state of the opening / closing body determined by the open recognition means continues for a predetermined period of time or more, it is deemed that the closing failure has occurred (see Figures 1, 3 and 4).

[0010] As a third feature, an imaging unit is provided that images the closing path of the opening / closing body, and the open recognition means processes the image data captured by the imaging unit to determine whether the opening / closing body is in an open state (see Figures 1, 3 and 4).

[0011] As a fourth feature, when the open recognizing means recognizes that the opening / closing body is in a closed state, the notification is stopped (see FIGS. 1, 3 and 4).

[0012] A fifth feature is that the door device normally holds the opening / closing body in the open position, and is equipped with an object recognition means for recognizing an object in the closing path of the opening / closing body, and when the object recognition means recognizes an object in the opening / closing path, it is deemed that a closing failure has occurred (see Figures 5, 6 and 7).

[0013] As a sixth feature, in addition to the above conditions, if it is determined that the object recognized by the object recognition means is an immobile object, it is deemed that the closure obstruction has occurred (see Figures 5, 6 and 7).

[0014] As a seventh feature, in addition to the above conditions, if it is determined that the object recognized by the object recognition means is not a person, it is deemed that the closure failure has occurred (see FIGS. 5, 6 and 7).

[0015] As an eighth feature, in addition to the above conditions, if the object recognition means continues to recognize an object for a predetermined time or longer, it is deemed that the closure failure has occurred (see FIGS. 5, 6 and 7).

[0016] As a ninth feature, when the object recognition means no longer recognizes the object, the notification is stopped (see FIGS. 5, 6 and 7).

[0017] As a tenth feature, a monitoring camera is provided for capturing and monitoring an image of the closing path of the opening / closing body, and the monitoring camera starts capturing an image at approximately the same time as the notification is given (see FIGS. 1 to 7).

[0018] As an eleventh feature, the imaging by the monitoring camera is stopped substantially simultaneously with the stopping of the notification of the closure failure (see FIGS. 1 to 7).

[0019] <Specific embodiment> Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings. In the following description, the term "visible direction" refers to the width direction (left-right direction) of the frame body. The term "visible direction" refers to the thickness direction of the frame that is approximately perpendicular to the "visible direction." Additionally, "inside the frame" means the inside of the frame body, and "outside the frame" means the outside of the frame body. Furthermore, the "opening width direction" refers to the lateral width direction of the opening that is opened and closed by the opening / closing body, and in this embodiment, this is the same direction as the "finding direction." Furthermore, the "door thickness direction" means the direction of the thickness of the opening / closing body, which in this embodiment is the same direction as the "projection direction."

[0020] In the following description, the term "closing failure" refers to a state in which the opening / closing body 20 in the open position cannot be closed. This closing failure includes a state in which the opening / closing body 20 (door) in the open position cannot be closed due to an object x1 (door stopper) (see FIG. 1), a state in which the opening / closing body 20' (fire door) in the open position cannot be closed due to an object x3 placed on it (see FIG. 5), etc. Furthermore, "evacuation route obstruction" refers to a state in which it is no longer possible to secure an evacuation route by opening the opening / closing body 20 that is in the closed position (see FIG. 2).

[0021] The door and window device 1 shown in Figures 1 and 2 comprises a frame body 10 with an opening in the center, an opening / closing body 20 that rotates to open and close within the frame body 10, a door closer 24 that automatically closes the opening / closing body 20 while applying resistance to the closing action of the opening / closing body 20, an imaging unit 31 that images the opening and closing path of the opening / closing body 20, an audio alarm unit 32 that outputs an alarm sound, and a monitoring and alarm control unit 33 that controls the output of the audio alarm unit 32 depending on the recognition status of objects x1 and x2, and detects the occurrence of a closing failure of the opening / closing body 20 or an obstruction to the evacuation route, and notifies the occurrence of these failures. This fitting device 1 can be used as a normally closed fire door that is normally closed, or as an on-demand fire door that closes only in the event of a fire upon receiving a disaster prevention signal.

[0022] The frame body 10 is configured in the shape of a concave frame when viewed from the front, and comprises a door-tail side frame member 11 that faces the door-tail portion of the opening / closing body 20 in the closed state, a door-tip side frame member 12 that faces the door-tip portion of the opening / closing body 20, and an upper frame member 13 that faces the upper end portion of the opening / closing body 20. A door stop portion 12a is provided on the inner side of the frame of the door-end side frame member 12 to receive the opening / closing body 20 when the door is fully closed.

[0023] The opening / closing body 20 is formed in a rectangular shape when viewed from the front and has a predetermined thickness. A knob 21 for opening and closing the opening and closing body 20 is provided on the front and back surfaces of the opening and closing body 20 near the center in the vertical direction on the door edge side. By rotating this knob 21, a latch 22 appears and disappears on the door edge surface of the opening and closing body 20. This latch 22 fits into and disengages from a latch receiver (not shown) of the door edge side frame member 12. In addition, this opening / closing body 20 is provided with a locking mechanism (not shown) that, if necessary, extends and retracts a deadbolt by operating a thumb turn or key, and engages and disengages it from a concave receiving seat (not shown) in the door-end frame member 12.

[0024] The trailing edge portion of the opening / closing body 20 is rotatably connected to the trailing edge frame member 11 via a plurality of hinges 23 spaced apart in the vertical direction. The opening / closing body 20 rotates around the hinge 23 as a fulcrum, and performs opening and closing operations by tracing an arc-shaped trajectory at the door edge.

[0025] The door closer 24 is a well-known mechanism that uses a plurality of link members, biasing members, dampers, etc. to automatically close the opening / closing body 20 slowly. This door closer 24 may be replaced with one having a structure other than that shown in the illustration, or may be omitted.

[0026] In the illustrated example, the imaging unit 31, the audio notification unit 32, and the monitoring notification control unit 33 are integrally configured by mounting a plurality of parts in a rectangular casing. As another example, some or all of the imaging unit 31, audio notification unit 32, and monitoring / notification control unit 33 may be configured as separate units. In addition, according to the illustrated example, the imaging unit 31, audio alarm unit 32, and monitoring alarm control unit 33 are attached to the upper wall surface of the frame body 10, but some or all of them may be provided in a location other than the illustrated example (for example, the frame body 10 or the ceiling part of the frame body, etc.).

[0027] The imaging unit 31 is a digital video camera that shoots moving images at a predetermined frame rate (for example, 30 fps). This imaging unit 31 has a function of recording sound simultaneously with moving image shooting, but it is also possible to have no sound recording function.

[0028] According to a preferred example of this embodiment, the imaging range 31a of the imaging unit 31 is set to include almost the entire lower end portion of the opening and closing path of the opening and closing body 20 (in other words, the area on the floor surface opposite the lower end of the opening and closing body 20). Therefore, if an object is placed in the opening and closing path, the object is photographed by the imaging unit 31 .

[0029] The audio notification unit 32 is a speaker that emits audio in response to a signal from the monitoring and notification control unit 33 .

[0030] The monitoring and reporting control unit 33 is an electric circuit including, for example, a microcomputer, a storage device, a relay circuit, etc., and operates according to a pre-stored program. The monitoring / announcement control unit 33 functions as an object recognition means for recognizing objects in cooperation with the imaging unit 31. That is, the monitoring / announcement control unit 33 operates according to a pre-stored program, thereby performing image processing on video data captured by the imaging unit 31 and recognizing an object x1 (or x2) or the like in the captured image. In a particularly preferred embodiment, the imaging data captured by the imaging unit 31 is analyzed, and based on the visual characteristics of the object x1 (or x2), it is recognized as being a person or something other than a human. For this recognition, an estimation model created in advance using artificial intelligence technology or the like may be used, for example.

[0031] Furthermore, the monitoring / announcement control unit 33 analyzes the image data captured by the imaging unit 31 to determine whether the recognized object x1 (or x2) is a stationary object (including a static object) or a moving object. This process can be performed, for example, by observing the coordinates of object x1 (or x2) between frames of captured video data, and if these coordinates change, it is determined that object x1 (or x2) is moving; otherwise, it is determined that object x1 (or x2) is stationary.

[0032] The monitoring / announcement control unit 33 also functions as an openness recognition unit that determines whether the opening / closing body 20 is in the open state by processing the image data captured by the imaging unit 31. This process may be performed, for example, by determining whether or not there is an image of a pre-stored part of the opening / closing body 20 (such as the surface or door edge of the opening / closing body 20) in the image captured by the imaging unit 31. That is, if there is no image of, for example, the door edge in the captured image, it can be determined that the opening / closing body 20 is in the fully closed position, and if there is an image of the door edge in the captured image, it can be determined that the opening / closing body 20 is in the open state (including the partially open state and the fully open position).

[0033] The power sources for the imaging unit 31, audio notification unit 32, monitoring and notification control unit 33, etc. can be commercial power sources, but it is preferable to use battery power sources in anticipation of power outages such as fires.

[0034] <Control example A> Next, an example of the control operation by the monitoring and reporting control unit 33 for the fitting device 1 configured as described above will be described in detail. First, the monitoring / announcement control unit 33 executes an initial setting mode in advance by a predetermined operation, and captures and stores an initial image of the opening / closing path with the opening / closing body 20 in the open state and objects x1 and x2 not in the imaging range 31a. Thereafter, the mode is switched to the monitoring mode automatically or by a predetermined operation, and the processing shown in the flowchart below is executed.

[0035] In the monitoring mode, the monitoring / announcement control unit 33 starts acquiring video data of the imaging range 31a by the imaging unit 31 (FIG. 3, step S1).

[0036] Next, the monitoring and alarm control unit 33 analyzes the video data acquired in step S1 to determine whether the opening / closing body 20 is in an open state (step S2), and if it is in an open state, proceeds to the next step, otherwise jumps to step S11.

[0037] In the next step S3, it is determined whether the open state of the opening / closing body 20 has continued for a predetermined time (5 minutes in the illustrated example) or more, and if it has continued, proceed to the next step; if not, skip the subsequent processing and return to step S1. Although not shown in the flowchart, the start of counting the predetermined time is the point in time when the open state of the opening-closing body 20 is first recognized in step S2. That is, when the open state of the opening-closing body 20 is first recognized in step S2, a timer (not shown) is started, and the processes from step S2 to step S3 are repeated until the count value of this timer reaches the predetermined time, and once the predetermined time has been reached, the process proceeds to the next step S4.

[0038] According to step S3, if the open state of the opening / closing body 20 continues for a predetermined time or longer, it is deemed that a closing obstruction due to an object x1 or the like has occurred. Here, the object x1 is a door stopper according to FIG. 1, but as another example, it may be an object other than the illustrated example placed on the floor surface.

[0039] In the next step S4, the occurrence of a closing failure of the opening / closing body 20 is notified, and the removal of the object and the closing of the opening / closing body 20 are prompted. This notification is a voice output from the voice notification unit 32, such as "Please close the door" or "Please remove the obstacle."

[0040] Although not shown in the flowchart, a preferred embodiment of step S4 is to transmit a notification signal wirelessly in addition to the notification by the audio notification unit 32. Specifically, the monitoring and alarm control unit 33 is equipped with a wireless module (more specifically, a wireless LAN (Wi-Fi) module, a specific low-power wireless module, etc.), and transmits a signal indicating that a closing failure has occurred in the opening / closing body 20, as well as images captured by the imaging unit 31, etc., via the wireless module and transmits them to a specific communication terminal (e.g., a smartphone, tablet PC, etc.) via a network line. According to this configuration, the communication terminal can check in real time whether there is a blocking fault, images captured by the imaging unit 31, and the like.

[0041] Next, the monitoring and alarm control unit 33 determines whether the opening / closing body 20 is in an open state (step S5), and if it determines that it is not in an open state, i.e., that it is in a closed state, it stops the alarm of the closing failure (step S6), and if not, it returns the processing to step S1. More specifically, the monitoring and alarm control unit 33 analyzes the video data acquired by the imaging unit 31, and if it determines that the opening and closing body 20 is already in a closed state, it stops the alarm by the audio alarm unit 32.

[0042] In step S11, the image data captured by the image capturing unit 31 is subjected to image processing to determine whether or not an object x2 is present in the captured image. If the object x2 is present, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S1. In the image processing of step S11, for example, the image data captured by the image capturing unit 31 is compared with the initial image of the opening and closing path described above, and if they do not match, it is determined that the object x2 is present, and if not, it is determined that the object x2 is not present. In the example shown in FIG. 2, the object x2 is a box-shaped object placed on the floor, but it may be an object other than that shown in the figure.

[0043] In the next step S12, it is determined whether or not the object x2 is a stationary object using the image processing described above. If it is determined that the object x2 is a stationary object, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S1.

[0044] In the next step S13, using the artificial intelligence technology described above, it is determined whether the object x2 recognized in step S11 is other than a human, and if it is determined to be other than a human, the processing proceeds to the next step; if not, the processing thereafter is skipped and the processing returns to step S1.

[0045] In the next step S14, it is determined whether the object x2 recognized in step S11 has been stationary for a predetermined time or more (five minutes in the illustrated example). If it is determined that the object has been stationary for a predetermined time or more, it is assumed that an evacuation route obstruction has occurred and the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S1. Although a detailed description of this process using a flowchart will be omitted, when it is first determined in step S12 that object x2 is an immobile object, a timer (not shown) is started, and the processes from step S12 to step S14 are repeated until the count value of this timer reaches the predetermined time. When the predetermined time has elapsed, the process proceeds to the next step S15.

[0046] In the next step S15, the occurrence of an evacuation route obstruction is notified, and removal of the object x2 is urged. This notification is a voice output from the voice notification unit 32, such as "The door won't open" or "Please move something."

[0047] Although not shown in the flowchart, a preferred embodiment of step S15 is to transmit a notification signal wirelessly in addition to the notification by the audio notification unit 32. More specifically, the monitoring and alarm control unit 33 transmits signals indicating that an evacuation route obstruction has occurred, images captured by the imaging unit 31, etc., using the wireless module described above, and transmits them via a network line to a specific communication terminal (e.g., a smartphone, tablet PC, etc.). According to this configuration, the communication terminal can check in real time whether there is an obstacle in the evacuation route, images captured by the imaging unit 31, and the like.

[0048] In the next step S16, similar to step S11 above, it is determined whether or not the object x2 in the opening and closing path has been recognized. If it has been recognized, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S1 above.

[0049] In the next step S17, the notification issued in step S15 is stopped, and the process returns to step S1.

[0050] Therefore, according to the above-described configuration of the fitting device 1 and control example A, it is possible to distinguish and recognize the occurrence of a closure failure or an evacuation route failure and to notify the same, and ultimately to prevent the occurrence of a closure failure or an evacuation route failure by, for example, encouraging the removal of abandoned objects.

[0051] <Control example B> Next, another control example will be described in detail. In order to execute the control example B shown in FIG. 4, an opening detection unit 41 and an object detection unit 42 are added to the above-mentioned fitting device 1 (see FIGS. 1 and 2). In addition, in this control example B, the above-mentioned imaging unit 31 is used as a monitoring camera that captures and monitors the closing path of the opening / closing body 20.

[0052] The opening detection unit 41 is a contact or non-contact sensor that emits a detection signal when the opening / closing body 20 is opened or closed, and is attached to, for example, an immovable part such as the frame body 10. For this opening detection unit 41, for example, a well-known limit switch or proximity switch can be used.

[0053] The object detector 42 is a sensor that detects an object in the opening / closing path of the opening / closing body 20 in a non-contact manner and emits a detection signal. The object detector 42 in the illustrated example is an area sensor (including a 3D sensor) that is provided on the wall surface of the frame body above the frame body 10 and detects objects in the opening and closing path of the opening and closing body 20 in a non-contact manner. The object detector 42 cooperates with the monitoring and reporting controller 33 to function as an object recognition means for detecting the objects x1 and x2 in the opening and closing path of the opening and closing body 20 in a non-contact manner.

[0054] As other examples of the object sensing unit 42, a multi-optical axis sensor, a phototube sensor, or other non-contact sensors can be used.

[0055] According to control example B shown in Figure 4, the monitoring and alarm control unit 33 first determines whether the opening / closing body 20 is in an open state based on the signal from the opening detection unit 41 (step S31), and if it is in an open state, proceeds to the next step, and if not, jumps to step S41.

[0056] In the next step S32, it is determined whether the open state of the opening / closing body 20 has continued for a predetermined time (5 minutes in the illustrated example) or more, and if it has continued, it is assumed that a closing failure has occurred and processing proceeds to the next step; if not, the subsequent processing is skipped and processing returns to step S31. That is, when the monitoring / alarm control unit 33 first detects the open state of the opening / closing body 20 in step S31, it starts a timer (not shown) and repeats the processing from step S31 to step S32 until the count value of this timer reaches the predetermined time, and proceeds to the next step S33 on the condition that the predetermined time has been reached.

[0057] In step S33, the imaging unit 31 (monitoring camera) is activated to start capturing video in the imaging range 31a.

[0058] In step S34, similarly to step S4, the occurrence of a closing failure of the opening / closing body 20 is notified, and the closing of the opening / closing body 20 is prompted. This notification starts approximately simultaneously with the start of imaging by the imaging unit 31.

[0059] Furthermore, in this step S34, although not shown in the flowchart, in addition to the above-mentioned notification by the voice notification unit 32, a signal indicating that a blocking failure has occurred and information such as image data captured by the imaging unit 31 are wirelessly transmitted to a specific communication terminal using the wireless module described above.

[0060] Meanwhile, the specific communication terminal functions by a pre-stored program (app) to receive the information via a network line or the like, display a push notification indicating that a closure failure has occurred, and display image data (video or still image) from the imaging unit 31 in response to a tap operation or the like on this notification. The communication terminal also stores a log of the date and time when the information was received, the image data, etc. These processes by the communication terminal are triggered by the reception of the closure failure information and are executed for a predetermined time (for example, several tens of seconds to several minutes).

[0061] The communication terminal may be any information and communication device with a network connection function, such as a smartphone, a laptop computer, a desktop computer, a tablet computer, or a wearable computer of various shapes (for example, a wristwatch type).

[0062] In the next step S35, it is determined whether the opening / closing body 20 is in a closed state based on the signal from the opening detection unit 41, and if it is determined that it is in a closed state, processing proceeds to the next step; if not, the subsequent processing is skipped and processing returns to step S31 above.

[0063] In the next step S36, the notification by the audio notification unit 32 is stopped. Then, in step S37, substantially simultaneously with the stopping, the imaging by the imaging unit 31 is stopped, and the process returns to step S31. Furthermore, in step S37, although not shown in the flowchart, the transmission of the above information (closure failure information, imaging data, etc.) in step S34 is stopped.

[0064] In step S41, it is determined from the detection signal of the object detection unit 42 whether or not there is an object x2 in the opening / closing path. If there is an object x2, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S31.

[0065] In the next step S42, the signal obtained by detecting the object x2 by the object detection unit 42 is It is determined whether the condition has continued for a predetermined time or more (five minutes in the illustrated example), and if it is determined that the condition has continued for a predetermined time or more, it is assumed that an evacuation route obstruction has occurred and the process proceeds to the next step; if not, the subsequent process is skipped and the process returns to step S31 above. In this process, when object x2 is first detected in step S41, a timer (not shown) is started, and the processes from step S41 to step S42 are repeated until the count value of this timer reaches the predetermined time. When the predetermined time has been reached, the process proceeds to the next step S43.

[0066] In step S43, the imaging unit 31 (monitoring camera) is activated to start capturing video in the imaging range 31a.

[0067] In step S44, similar to step S15, the occurrence of an evacuation route obstruction is notified and the removal of the object x2 is urged. The notification starts substantially simultaneously with the start of imaging by the imaging unit 31.

[0068] Furthermore, in this step S44, although not shown in the flowchart, in addition to the above-mentioned notification by the voice notification unit 32, a signal indicating that an evacuation route obstruction has occurred, as well as information such as image data captured by the imaging unit 31, are wirelessly transmitted to a specific communication terminal using the wireless module described above.

[0069] Meanwhile, the specific communication terminal, functioning according to a pre-stored program (app), receives the information via a network line or the like, displays a push notification indicating that an evacuation route obstruction has occurred, and displays image data (video or still image) captured by the imaging unit 31 on a display in response to a tap operation or the like on the notification. The communication terminal also stores a log of the date and time when the information was received, the image data, etc. These processes by the communication terminal are triggered by the reception of the evacuation route obstruction information and are executed for a predetermined time (for example, several tens of seconds to several minutes).

[0070] In the next step S45, it is determined from the detection signal of the object detection unit 42 whether or not the object x2 has disappeared. If the object x2 has disappeared, the process proceeds to the next step; if not, the subsequent steps are skipped and the process returns to step S31.

[0071] In the next step S46, the notification etc. in step S44 is stopped. Then, in step S47, almost simultaneously with this stopping, the imaging by the imaging unit 31 is stopped. Furthermore, in step S47, although not shown in the flowchart, the transmission of the above information (opening / closing route fault information, imaging data, etc.) in step S44 is stopped.

[0072] Therefore, according to control example B, in addition to the effects of control example A described above, the time required for starting up the imaging unit 31 and transmitting information can be minimized, thereby reducing consumption of batteries and other devices that serve as power sources for the monitoring and alarm control unit 33, imaging unit 31, etc. Furthermore, it is possible to transmit information on closures and evacuation route obstructions to specific communication terminals and record this information. It is also possible to check for the presence of outsiders or suspicious individuals from the recorded images of the imaging unit 31. The communication terminal may store the information in a log in a storage device of the communication terminal, or may store the information in a cloud server (not shown) on a network line.

[0073] <Door and window equipment 2> The fitting device 2 described below is a modified version of the fitting device 1 described above, so the modified parts will be mainly described in detail, and common parts will be given the same symbols and redundant explanations will be omitted.

[0074] The fitting device 2 shown in Figure 5 comprises a frame body 10' attached along the wall surface of a passage such as a corridor, an opening / closing body 20' that rotates from an open position fitted within the frame body 10' to a closed position at which it closes the passage, an imaging unit 31 that images an object x3 in the opening / closing path of the opening / closing body 20', an audio alarm unit 32 that outputs an alarm sound, and a monitoring / alarm control unit 33 that controls the output of the audio alarm unit 32 depending on the recognition status of the object x3. This fitting device 2 constitutes a fire door that holds the opening / closing body 20' in an open position under normal circumstances and closes the opening / closing body 20' in a closed position in the event of a fire, thereby forming a fire compartment.

[0075] The frame 10' is configured as a concave frame when viewed from the front, and includes a trailing edge frame member 11' that faces the trailing edge of the opening / closing body 20' when it is in the open position, a leading edge frame member 12' that faces the leading edge of the opening / closing body 20', and an upper edge frame member 13' that faces the upper end of the opening / closing body 20'. The frame 10' is fitted and fixed into a recess formed in the passage wall.

[0076] The opening / closing body 20' comprises a substantially rectangular partition section 25 that is capable of closing the passage and is arranged at a substantially right angle to the passageway direction, and an escape hatch 26 that rotates within the partition section 25 to open and close.

[0077] The partition 25 is formed in a substantially rectangular plate shape that fits into the frame body 10', and its trailing edge is rotatably supported on the trailing edge frame member 11' via a hinge, etc. This partition 25 rotates approximately 90 degrees toward the aisle to close the aisle.

[0078] A rectangular opening is provided at the center of the partition 25, and a slatted door 26 is fitted into this opening. The swivel door 26 is a swing door (door) whose tail end is supported on the inner edge of the opening via a hinge. The swivel door 26 is disengaged from the partition part 25 by operating a knob or the like and rotates to open and close the opening.

[0079] In this fitting device 2, the imaging unit 31, audio notification unit 32 and monitoring / notification control unit 33 have substantially the same configuration as those in the fitting device 1, and are fixed to an immovable part such as a passage wall surface. The imaging range 31a of the imaging unit 31 is set so as to include almost the entire lower end portion of the opening / closing path of the opening / closing body 20' (the sector-shaped range indicated by the two-dot chain line in FIG. 5).

[0080] <Control example C> Next, a control example C of the fitting device 2 will be described (see FIG. 6). First, the monitoring and notification control unit 33 executes an initial setting mode in advance by a predetermined operation, and captures and stores an initial image of the opening and closing path with the opening and closing body 20' in the open position (the position shown in Figure 5) and with no object x3 in the imaging range 31a. Thereafter, the mode is switched to the monitoring mode automatically or by a predetermined operation, and the processing shown in the flowchart below is executed.

[0081] In the monitoring mode, the monitoring / announcement control unit 33 starts acquiring video data of the imaging range 31a by the imaging unit 31 (FIG. 6, step S21).

[0082] In the next step S22, the image data captured by the imaging unit 31 is subjected to image processing to determine whether or not the object x3 is present in the captured image. If the object x3 is present, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S21. In the image processing of step S22, for example, the image data captured by the image capturing unit 31 is compared with the initial image of the opening and closing path described above, and if they do not match, it is determined that the object x3 is present, and if not, it is determined that the object x3 is not present.

[0083] In the next step S23, it is determined whether or not object x3 is a stationary object using the image processing described above. If it is determined that object x3 is a stationary object, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S21.

[0084] In the next step S24, using the artificial intelligence technology described above, it is determined whether or not the object x3 is other than a human. If it is determined to be other than a human, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S21.

[0085] In the next step S25, it is determined whether object x3 has been recognized for a predetermined time or more. If it is determined that object x3 has been recognized for the predetermined time, it is assumed that a closure failure has occurred and processing proceeds to the next step; if not, the subsequent processing is skipped and processing returns to step S21 above. More specifically, when object x3 is first recognized in step S22, a timer (not shown) is started, and the process from step S22 to step S25 is repeated until the count value of this timer reaches the predetermined time. Once the predetermined time has been reached, the process proceeds to the next step S26.

[0086] In the next step S26, the occurrence of a closing failure of the opening-closing body 20' is notified, and the removal of the object x3 and the closing of the opening-closing body 20' are prompted. This notification is a voice output from the voice notification unit 32, such as "The passage cannot be closed" or "Please remove the obstacle."

[0087] In the next step S27, similar to step S22 above, it is determined whether or not the object x3 in the opening and closing path has been recognized. If it has been recognized, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S21 above.

[0088] In the next step S28, the notification issued in step S26 is stopped, and the process returns to step S21.

[0089] Therefore, according to the above-described configuration of the door and window device 2 and control example C, if an object x3 that acts as an obstacle is left in the opening and closing path of the opening and closing body 20', it is possible to notify of the occurrence of a closing failure, and ultimately to prompt the removal of the left object, thereby preventing the occurrence of a closing failure.

[0090] <Control example D> Next, control example D shown in FIG. 7 will be described in detail. In order to execute this control example D, the opening detection unit 41 and the object detection unit 42 described above are provided on the passage wall surface of the fitting device 2 (see FIG. 5). In addition, in this control example D, the above-mentioned imaging unit 31 is used as a monitoring camera that captures and monitors the opening and closing path of the opening and closing body 20'.

[0091] According to control example D, the monitoring and alarm control unit 33 first determines whether or not an object x3 is present based on the detection signal from the object detection unit 42 (step S51), and if an object x3 is present, proceeds to the next step; if not, repeats the processing of step S51.

[0092] In the next step S52, it is determined whether or not the detection signal of the object x3 by the object detection unit 42 continues for a predetermined time (five minutes in the illustrated example) or more. If it is determined that the detection signal has continued for the predetermined time or more, closure If it is determined that a fault has occurred, the process proceeds to the next step; if not, the process skips the subsequent steps and returns to step S51. In this process, when object x3 is first detected in step S51, a timer (not shown) is started, and the processes from step S51 to step S52 are repeated until the count value of this timer reaches the predetermined time. Once the predetermined time has been reached, the process proceeds to the next step S53.

[0093] In the next step S53, the imaging unit 31 (monitoring camera) is activated to start capturing video within the imaging range 31a.

[0094] In the next step S54, similar to step S26, the occurrence of a closing failure of the opening-closing body 20' is notified, and the removal of the object x3 and the closing of the opening-closing body 20' are prompted.

[0095] Furthermore, in this step S54, although not shown in the flowchart, in addition to the above-mentioned notification by the voice notification unit 32, a signal indicating that a blocking failure has occurred and information such as image data captured by the imaging unit 31 are wirelessly transmitted to a specific communication terminal using the wireless module described above. In response to this, the specific communication terminal, as in control example C, displays a push notification indicating that a closure failure has occurred, and in response to a tap operation or the like in response to this notification, displays image data (video or still image) from the imaging unit 31, or logs the date and time of reception and the image data, etc.

[0096] In the next step S55, it is determined from the detection signal of the object detection unit 42 whether or not the object x3 has disappeared. If the object x3 has disappeared, the process proceeds to the next step; if not, the subsequent steps are skipped and the process returns to step S51.

[0097] In the next step S56, the notification issued in step S54 is stopped, and the process proceeds to the next step.

[0098] In the next step S57, imaging by the imaging unit 31 (monitoring camera) is stopped, and the process returns to step S51. Furthermore, in step S57, the transmission of the above information (blocking failure information, imaging data, etc.) in step S54 is stopped.

[0099] Therefore, with the above-described configuration of the door and window device 2 and control example D, it is possible to obtain effects that are approximately the same as those of control example C, and in addition, it is possible to minimize the startup time of the imaging unit 31, thereby reducing consumption of batteries and other devices that serve as power sources for the imaging unit 31 and the monitoring and alarm control unit 33. Furthermore, it is possible to transmit blocking failure information to specific communication terminals and record this information. It is also possible to check for the presence of outsiders or suspicious individuals from the recorded images of the imaging unit 31.

[0100] <Other variations> In the above embodiment of the door and window device 2, the opening and closing body 20' is configured to be closed manually, but in another example of the present invention, the opening and closing body 20' can also be configured to be closed automatically by an automatic closing device or the like in response to a signal during a disaster, etc.

[0101] According to the above embodiment, the fitting device is a hinged door or a hinged door type fire door, but the fitting device of the present invention may be any device that rotates its opening and closing body to close, such as a folding door device, a balance door that rotates and slides to close, a window that rotates to close, or a rotating partition other than the illustrated example.

[0102] Furthermore, in the above-described embodiment, the configuration for notifying the occurrence of a closing failure can also be applied to a sliding door device in which the opening / closing body performs a linear closing operation, a sliding door type window device, and the like.

[0103] The present invention is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the present invention. [Explanation of symbols]
