By rotating the knob 21 , the latch 22 appears and disappears on the door tip surface of the opening/closing body 20 . The latch 22 is fitted into and removed from a latch receiver (not shown) of the door frame member 12 .
In addition, the opening/closing body 20 is provided with a locking mechanism ( (not shown), etc. are provided.

Further, the door bottom side portion of the opening/closing body 20 is rotatably connected to the door bottom side frame member 11 via a plurality of hinges 23 spaced apart in the vertical direction.
The opening/closing body 20 rotates about the hinge 23 as a fulcrum, so that the opening/closing operation is performed while drawing an arc-shaped locus by the door tip portion.

The door closer 24 is a well-known mechanism that slowly and automatically closes the opening/closing body 20 using a plurality of link members, biasing members, dampers, and the like.
The door closer 24 may be replaced with a structure other than the illustrated example, or may be omitted.

According to the illustrated example, the imaging unit 31, the audio notification unit 32, and the monitoring notification control unit 33 are configured integrally by, for example, mounting a plurality of components in a rectangular casing.
As another example, part or all of the imaging unit 31, the audio notification unit 32, and the monitoring notification control unit 33 may be configured separately.
In addition, according to the illustrated example, the imaging unit 31, the audio notification unit 32, and the monitoring notification control unit 33 are attached to the frame wall surface on the upper side of the frame 10. You may make it provide in a site|part (for example, the frame 10, a frame|body ceiling part, etc.).

The imaging unit 31 is a digital video camera that shoots moving images at a predetermined frame rate (eg, 30 fps). The imaging unit 31 has a function of recording moving images at the same time, but it is also possible not to have a recording function.

According to a preferred example of the present embodiment, the imaging range 31a by the imaging unit 31 is the lower end side portion of the opening/closing path of the opening/closing member 20 (in other words, the floor surface facing the lower end portion of the opening/closing member 20 that opens and closes). upper range).
Therefore, when an object is placed in the opening/closing path, this object is photographed by the imaging section 31 .

The voice notification unit 32 is a speaker that emits voice according to a signal from the monitoring notification control unit 33 .

The monitoring/reporting control unit 33 is, for example, an electric circuit including a microcomputer, a storage device, a relay circuit, etc., and operates according to a pre-stored program.
The monitoring/reporting control unit 33 cooperates with the imaging unit 31 to function as object recognition means for recognizing an object. That is, the monitoring notification control unit 33 operates according to a program stored in advance, performs image processing on the moving image data captured by the imaging unit 31, and recognizes the object x1 (or x2) and the like in the captured image.
In a particularly preferable mode, the image data captured by the image capturing unit 31 is analyzed to determine whether the object x1 (or x2) is a non-human object or a person based on the visual characteristics of the object x1 (or x2). , distinguish and recognize.
For this recognition, for example, an estimation model created in advance by artificial intelligence technology or the like may be used.

In addition, the monitoring/reporting control unit 33 analyzes the image data captured by the image capturing unit 31 to determine whether the recognized object x1 (or x2) is a non-moving object (including a stationary object) or a moving object. to judge.
In this process, for example, the coordinates of the object x1 (or x2) are observed between frames of captured video data, and if the coordinates change, it is determined that the object x1 (or x2) is moving, Otherwise, it should be determined that the object x1 (or x2) is stationary.

The monitoring notification control unit 33 also functions as an open recognizing means for determining whether or not the opening/closing member 20 is in the open state by processing image data captured by the image capturing unit 31 .
This process may be determined by, for example, whether or not there is an image of a part of the opening/closing body 20 (the surface of the opening/closing body 20, the edge of the door, etc.) stored in advance in the image captured by the imaging unit 31 . That is, if there is no image of, for example, the end of the door 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 end of the door in the captured image, the opening/closing body 20 is in the open state ( (including the halfway open state and the fully open position).

The imaging unit 31, the voice notification unit 32, the monitoring notification control unit 33, and the like can be powered by a commercial power supply, but it is preferable to use a battery power supply in case of a power failure such as a fire.

<Control example A>
Next, an example of the control operation by the monitoring notification control unit 33 will be described in detail for the fitting device 1 having the above configuration.
First, the monitoring notification control unit 33 executes an initial setting mode by a predetermined operation in advance, and captures an initial image of the opening/closing path in a state where the opening/closing body 20 is open and the objects x1 and x2 are not in the imaging range 31a. Remember.
After that, the mode is switched to the monitor mode automatically or by a predetermined operation, and the process of the flow chart described later is executed.

In the monitoring mode, the monitoring notification control unit 33 starts acquisition of moving image data of the imaging range 31a by the imaging unit 31 (FIG. 3, step S1).

Next, the monitoring notification control unit 33 analyzes the moving image data acquired in step S1 to determine whether or not the opening/closing body 20 is in the open state (step S2). If not, the process jumps to step S11.

In the next step S3, it is determined whether or not the open state of the opening/closing member 20 has continued for a predetermined time (five minutes in the illustrated example) or longer. The subsequent processing is skipped and the process returns to step S1.
Although not shown in the flow chart, the counting of the predetermined time is started when the open state of the opening/closing member 20 is first recognized in step S2. That is, when the open state of the opening/closing member 20 is first recognized in step S2, a timer (not shown) is started, and the processing from step S2 to step S3 is performed until the count value of the timer reaches the predetermined time. is repeated, and on the condition that the predetermined time has elapsed, the process proceeds to the next step S4.

According to step S3, when the opening state of the opening/closing member 20 continues for a predetermined time or longer, it is assumed that the object x1 or the like causes a closing failure.
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.

In the next step S4, the occurrence of the closing failure of the opening/closing member 20 is reported, and removal of the object and closing of the opening/closing member 20 are urged.
This notification is an audio output by the audio notification unit 32, such as "Please close the door" or "Please remove the obstacle".

Also, although not shown in the flowchart, as a preferred mode of this step S4, in addition to the notification by the voice notification unit 32, a notification signal may be wirelessly transmitted.
Specifically, the monitoring/reporting control unit 33 includes a wireless module (specifically, a wireless LAN (Wi-Fi) module, a specific low-power wireless module, etc.), A signal indicating that the user is present, an image captured by the imaging unit 31, and the like are transmitted by the wireless module and transmitted to a specific communication terminal (for example, a smart phone, a tablet computer, etc.) via a network line.
According to this configuration, on the communication terminal side, it is possible to check the presence or absence of a closing failure, the image captured by the imaging unit 31, and the like in real time.

Next, the monitoring/reporting control unit 33 determines whether or not the opening/closing member 20 is in the open state (step S5). is stopped (step S6), and if not, the process returns to step S1.
More specifically, when the monitoring notification control unit 33 analyzes the moving image data acquired by the imaging unit 31 and determines that the opening/closing member 20 is already closed, the audio notification unit 32 Stop the notification.

Further, in step S11, image processing is performed on the imaged data by the imaging unit 31 to determine whether or not the object x2 is present in the imaged image. Skip the subsequent processes and return to step S1.
In the image processing in step S11, for example, the image data captured by the image capturing unit 31 is compared with the initial image of the open/close path described above. Consider.
Although the object x2 is a box-shaped object placed on the floor according to the example of FIG. 2, it may be an object other than the illustrated example.

In the next step S12, it is determined whether or not the object x2 is an immovable object by the image processing or the like described above. If not, skip the subsequent processes and return to step S1.

In the next step S13, it is determined whether or not the object x2 recognized in step S11 is other than a person by the artificial intelligence technology or the like described above. If not, skip the subsequent processes and return to step S1.

In the next step S14, it is determined whether or not the object x2 recognized in step S11 is stationary for a predetermined time (five minutes according to the illustrated example) or not. It is assumed that a path failure has occurred, and the process proceeds to the next step. If not, the subsequent processes are skipped and the process returns to step S1.
This process will not be described in detail with reference to the flow chart, but when it is first determined in step S12 that the object x2 is an immovable object, a timer (not shown) is started, and the count value of this timer is equal to the predetermined value. The processing from step S12 to step S14 is repeated until the time is reached, and on the condition that the predetermined time is reached, the processing proceeds to the next step S15.

In the next step S15, the occurrence of the evacuation route obstruction is notified and the removal of the object x2 is urged.
This notification is an audio output by the audio notification unit 32, such as "The door will not open" or "Please remove the object."

Also, although not shown in the flowchart, as a preferred mode of this step S15, in addition to the notification by the voice notification unit 32, a notification signal may be wirelessly transmitted.
Specifically, the monitoring/reporting control unit 33 uses the wireless module described above to transmit a signal indicating that an evacuation route failure has occurred, an image captured by the imaging unit 31, and the like, and connects the network line. to a specific communication terminal (for example, a smart phone, a tablet computer, etc.).
According to this configuration, on the communication terminal side, it is possible to check the presence or absence of an obstacle in the evacuation route, the image captured by the imaging unit 31, and the like in real time.

In the next step S16, in the same manner as in step S11, it is determined whether or not the object x2 in the open/close path is no longer recognized. Skip the process and return to step S1.

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

Therefore, according to the fitting device 1 configured as described above and the control example A, it is possible to distinguish between the occurrence of a closing obstacle or an evacuation route obstacle and notify the operator. It is possible to prevent the occurrence of evacuation route obstacles.

<Control example B>
Next, another control example will be described in detail.
In order to execute the control example B shown in FIG. 4, the fitting device 1 is added with an open detection section 41 and an object detection section 42 (see FIGS. 1 and 2).
Further, in this control example B, the imaging unit 31 described above is used as a monitoring camera that images and monitors the inside of the closed path of the opening/closing body 20 .

The open sensor 41 is a contact or non-contact sensor that emits a sensing signal when the open/close body 20 is opened or closed, and is attached to a stationary portion such as the frame 10, for example. For example, a well-known limit switch, proximity switch, or the like can be used for the open detection unit 41 .

The object sensing unit 42 is a sensor that senses an object in the opening/closing path of the opening/closing member 20 without contact and emits a sensing signal.
The object sensing unit 42 in the illustrated example is an area sensor (including a 3D sensor) that is provided on the wall surface of the frame above the frame 10 and senses an object in the opening/closing path of the opening/closing body 20 in a non-contact manner.
The object sensing section 42 cooperates with the monitoring/reporting control section 33 to function as an object recognizing means for non-contact sensing of the objects x1 and x2 in the opening/closing path of the opening/closing body 20 .

As other examples of the object sensing section 42, it is possible to use a multi-optical axis sensor, a phototube sensor, and other non-contact sensors.

According to control example B shown in FIG. If so, the process proceeds to the next step; otherwise, the process jumps to step S41.

In the next step S32, it is determined whether or not the open state of the opening/closing member 20 has continued for a predetermined time (five minutes in the illustrated example) or longer. The process proceeds to the step, and if not, the subsequent processes are skipped and the process returns to step S31.
That is, when the monitoring/reporting control unit 33 first senses the open state of the opening/closing member 20 in step S31, it starts a timer (not shown). The processing from S31 to step S32 is repeated, and on the condition that the predetermined time has elapsed, the processing proceeds to the next step S33.

In step S33, the imaging unit 31 (surveillance camera) is activated to start moving image shooting in the imaging range 31a.

In step S34, similar to step S4, the occurrence of the closing failure of the opening/closing member 20 is notified, and the closing of the opening/closing member 20 is urged. The start of this notification is substantially simultaneous with the start of imaging by the imaging unit 31 .

Furthermore, in this step S34, although not shown in the flow chart, in addition to the notification by the voice notification unit 32, the above-described wireless module is used to indicate that a closing failure has occurred in a specific communication terminal. and information such as data captured by the imaging unit 31 are transmitted wirelessly.

On the other hand, the specific communication terminal functions according to a pre-stored program (application), receives the information via a network line, etc., and displays a push notification indicating that a closure failure has occurred. , the image data (moving image or still image) from the imaging unit 31 is displayed on the display in response to a tap operation or the like in response to this notification. Further, the communication terminal stores the date and time when the information is received, the image data, and the like in a log. These processes by the communication terminal are executed for a predetermined time (for example, several tens of seconds to several minutes) triggered by reception of closure failure information.

The communication terminal may be an information communication device having a network connection function, such as a smart phone, a notebook computer, a desktop computer, a tablet computer, and wearable computers of various shapes (for example, wristwatch type).

In the next step S35, it is determined whether or not the opening/closing body 20 is in the closed state based on the signal from the open sensing section 41. If it is determined to be in the closed state, the process proceeds to the next step, otherwise. If so, the subsequent processing is skipped and the processing is returned to step S31.

In the next step S36, the notification by the voice notification unit 32 is stopped.
Then, in step S37, substantially at the same time as the stop, the imaging unit 31 stops imaging, and the process returns to step S31.
Further, in this step S37, although not shown in the flow chart, transmission of the above information (closure failure information, imaging data, etc.) in step S34 is stopped.

Also, in step S41, it is judged from the sensing signal of the object sensing section 42 whether or not there is an object x2 in the open/close path. is skipped, and the process returns to step S31.

In the next step S42, the signal obtained by sensing the object x2 by the object sensing unit 42 is
It is determined whether or not it has continued for a predetermined time (five minutes according to the illustrated example), and if it is determined that it has continued for a predetermined time or more, it is regarded as an evacuation route failure, and the process proceeds to the next step. If not, the subsequent processing is skipped and the processing is returned to step S31.
In this process, when the 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. , the process proceeds to the next step S43 on the condition that the predetermined time has elapsed.

In step S43, the imaging unit 31 (surveillance camera) is activated to start capturing moving images in the imaging range 31a.

In step S44, similarly to step S15, the occurrence of the evacuation route obstruction is notified, and the removal of the object x2 is urged. The start of this notification is substantially simultaneous with the start of imaging by the imaging unit 31 .

Furthermore, in this step S44, although not shown in the flowchart, in addition to the notification by the voice notification unit 32, an evacuation route failure is generated in a specific communication terminal using the wireless module described above. Information such as a signal indicating that the image pickup unit 31 has been picked up and data picked up by the image pickup unit 31 are transmitted wirelessly.

On the other hand, the specific communication terminal functions according to a pre-stored program (application), receives the information via a network line, etc., and displays a push notification indicating that an evacuation route failure has occurred. Then, the image data (moving image or still image) from the imaging unit 31 is displayed on the display according to the tap operation or the like in response to this notification. Further, the communication terminal stores the date and time when the information is received, the image data, and the like in a log. These processes by the communication terminal are triggered by the reception of the evacuation route failure information and executed for a predetermined period of time (for example, several tens of seconds to several minutes).

In the next step S45, it is determined whether or not the object x2 has disappeared from the sensing signal of the object sensing section 42. If the object x2 has disappeared, the processing proceeds to the next step, otherwise the subsequent processing is skipped. , the process returns to step S31.

In the next step S46, the notification or the like in step S44 is stopped.
Then, in step S47, imaging by the imaging unit 31 is stopped substantially at the same time as this stop.
Further, in this step S47, although not shown in the flow chart, transmission of the above information (opening/closing path failure information, imaging data, etc.) in step S44 is stopped.

Therefore, according to the control example B, in addition to the effect of the above control example A, the time for starting the imaging unit 31 and transmitting information is minimized, and the power supply for the monitoring notification control unit 33, the imaging unit 31, etc. Consumption of a battery or the like can be reduced.
Furthermore, it is possible to transmit closure failure information and evacuation route failure information to a specific communication terminal, and record such information. It is also possible to confirm the presence or absence of an outsider or a suspicious person from the recorded image of the imaging unit 31 .
The log storage of the information by the communication terminal may be stored in the storage device of the communication terminal, or may be stored in a cloud server (not shown) in the network line.

<Joint device 2>

<Control example C>
Next, a control example C of the fitting device 2 will be described (see FIG. 6).
First, the monitoring notification control unit 33 executes the initial setting mode by a predetermined operation in advance, and sets the opening/closing path in a state where the opening/closing member 20' is in the open position (the position shown in FIG. 5) and no object x3 is present in the imaging range 31a. An initial image of is captured and stored.
After that, the mode is switched to the monitor mode automatically or by a predetermined operation, and the process of the flow chart described later is executed.

In the next step S22, image processing is performed on the imaged data by the imaging unit 31 to determine whether or not the object x3 is present in the imaged image. Skip the subsequent processes and return to step S21.
In the image processing in step S22, for example, the image data captured by the image capturing unit 31 is compared with the initial image of the open/close path described above. Consider.

In the next step S23, it is determined whether or not the object x3 is an immovable object by the image processing or the like described above. If not, the subsequent processing is skipped and the processing is returned to step S21.

In the next step S24, it is determined whether or not the object x3 is other than a person by the artificial intelligence technology or the like described above. Otherwise, the process after that is skipped and the process returns to step S21.

In the next step S25, it is determined whether or not the object x3 is recognized for a predetermined time or longer. If not, the subsequent processing is skipped and the processing is returned to step S21.
More specifically, this process starts a timer (not shown) when the object x3 is first recognized in step S22. to step S25 are repeated, and on condition that the predetermined time has elapsed, the process proceeds to the next step S26.

In the next step S26, the occurrence of the closing failure of the opening/closing body 20' is reported to prompt the removal of the object x3 and the closing of the opening/closing body 20'.
This notification is an audio output by the audio notification unit 32, such as "passage cannot be closed" or "please remove obstacles".

In the next step S27, in the same manner as in step S22, it is determined whether or not the object x3 in the open/close path is no longer recognized. The process is skipped and the process returns to step S21.

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

Therefore, according to the fitting device 2 configured as described above and the control example C, when the obstacle x3 is left in the opening/closing path of the opening/closing body 20', it is possible to notify the occurrence of the closing failure. As a result, it is possible to promote removal of the abandoned object and prevent the occurrence of closure failure.

<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 fitting device 2 is provided with the above-described opening sensor 41 and object sensor 42 on the passage wall surface (see FIG. 5).
Further, in this control example D, the imaging unit 31 described above is used as a monitoring camera that images and monitors the inside of the opening/closing path of the opening/closing member 20'.

According to the control example D, the monitoring/notification control unit 33 first determines whether or not the object x3 is present from the sensing signal of the object sensing unit 42 (step S51), and if the object x3 is present, the process proceeds to the next step. , otherwise the process of step S51 is repeated.

In the next step S52, it is determined whether or not the sensing signal of the object x3 by the object sensing section 42 has continued for a predetermined time (5 minutes in the illustrated example) or longer. If so, it is assumed that an evacuation route failure has occurred, and the process proceeds to the next step. If not, the subsequent processes are skipped and the process returns to step S51.
In this process, when the 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 value counted by this timer reaches the predetermined time. , the process proceeds to the next step S53 on the condition that the predetermined time has elapsed.

In the next step S53, the imaging unit 31 (surveillance camera) is activated to start moving image shooting in the imaging range 31a.

In the next step S54, similar to step S26, occurrence of a closing failure of the opening/closing body 20' is reported to prompt removal of the object x3 and closing of the opening/closing body 20'.

Furthermore, in this step S54, although not shown in the flow chart, in addition to the notification by the voice notification unit 32, the above-described wireless module is used to indicate that a closing failure has occurred in a specific communication terminal. and information such as data captured by the imaging unit 31 are transmitted wirelessly.
On the other hand, the specific communication terminal displays a push notification indicating that a closing failure has occurred, as in control example C, and according to a tap operation or the like in response to this notification, the image data from the imaging unit 31 is displayed. (moving or still image) is displayed, and the date and time of reception, the image data, etc. are saved in a log.

In the next step S55, it is determined whether or not the object x3 has disappeared from the sensing signal of the object sensing section 42. If the object x3 has disappeared, the processing proceeds to the next step, otherwise the subsequent processing is skipped. Then, the process returns to step S51.

In the next step S56, the notification given in step S54 is stopped, and the process proceeds to the next step.

In the next step S57, the imaging unit 31 (surveillance camera) stops imaging, and the process returns to step S51.
Furthermore, in step S57, transmission of the above information (closure failure information, imaging data, etc.) in step S54 is stopped.

Therefore, according to the fitting device 2 and the control example D configured as described above, in addition to obtaining substantially the same effects as those of the control example C, the activation time of the imaging unit 31 is minimized, and the imaging unit 31 and the monitor are Consumption of the battery or the like that is the power source for the notification control unit 33 can be reduced.
Furthermore, closure failure information can be transmitted to a specific communication terminal, and such information can be recorded. It is also possible to confirm the presence or absence of an outsider or a suspicious person from the recorded image of the imaging unit 31 .
