Next, the operation of the elevator 1 will be described with reference to the drawings.
FIG. 5 is a flowchart for explaining the operation of the elevator provided with the elevator landing fixture detection apparatus according to one embodiment of the present invention.
In FIG. 5, steps 101 to 120 are denoted as S101 to S120 for convenience of explanation.

  In step 101, the elevator main body control unit 41 determines whether or not the main inspection start operation has been executed, and when determining that the main inspection start operation has not been executed, controls the elevator main body 10 in the normal operation mode ( Step 102). The normal operation mode is a mode for carrying a general user on the car 30 and is designated by the destination floor designated by the destination floor button 33a of the car operation panel 33 or the hall call button 23. The elevator 30 is opened and closed by raising and lowering the car 30 on the floor of the landing 20.

When the elevator main body control unit 41 determines in step 101 that the main inspection start operation has been executed, the elevator body control unit 41 performs an attachment confirmation car control described below (step 103). That is, here, this inspection start operation is used to output a car control command for checking an attachment.
In the attachment confirmation car control, the floor to which the check tag 70 is attached is set as a destination floor, and each time the car 30 reaches the landing 20 of the set floor, the elevator door 28 is opened and closed. A check signal is output when the elevator door 28 is fully opened.

  As will be described later, each time the check signal is output, the attachment detection device 50 is controlled to detect the presence or absence of the check tag 70. That is, when the attachment control car control is completed, the attachment detection device 50 determines the presence or absence of the inspection tags 70 for all the landings 20 on the floor to which the inspection tags 70 are attached. Further, the attachment detection device 50 is configured to output information on the presence or absence of the inspection tag 70 at each landing 20 as attachment confirmation information.

  In step 104, the elevator body control unit 41 refers to the attachment confirmation information and determines whether or not the inspection tags 70 are present in all the landings 20 to which the inspection tags 70 are desired to be attached. If there is no check tag 70, the process proceeds to step 105, and if there is a check tag 70, the process proceeds to step 107.

In step 105, the elevator main body control unit 41 determines whether or not an attachment reconfirmation command has been input. If it is determined that no attachment reconfirmation instruction has been input, step 105 is repeated and the attachment reconfirmation command is input. If it is determined that the process has been performed, the process proceeds to step 106.
In step 106, the elevator body control unit 41 performs car control for attaching portion reconfirmation, and returns to step 104.
In the car control for reconfirmation of the attachment, the floor having the landing 20 where the check tag 70 is not detected is set as the destination floor, and each time the car 30 reaches the landing 20 of the set floor, the elevator The door 28 is opened and a check signal is output when the elevator door 28 is fully opened.

  In step 107, the elevator body control unit 41 sets the operation mode of the elevator body 10 to the inspection mode. Note that the inspection mode is, for example, that the elevator body control unit 41 generates the monitoring device even when the hall call button 23 blinks or an operation that is normally determined to be abnormal is performed by this inspection work. In this mode, the monitoring device 75 invalidates the abnormal signal output to 75 and does not notify the monitoring center 80 of the occurrence of the abnormality.

Next, in step 108, the elevator body control unit 41 starts the time count of the timer 42.
In step 109, the elevator main body control unit 41 determines whether or not an inspection end operation has been executed. If it is determined that the inspection end operation has not been executed, the process proceeds to step 110.

In step 110, the elevator body control unit 41 determines whether or not the time counted by the timer 42 has passed an inspection delay authorization time described below.
The inspection delay authorization time is set longer than the expected time required for the main inspection work of the elevator 1 by a predetermined time.

  In step 110, the elevator main body control unit 41 returns to step 109 when determining that the time of the timer 42 has not passed the inspection delay authorized time, and proceeds to step 111 when determining that the inspection delay authorized time has elapsed. .

In step 111, the elevator body control unit 41 turns on the delay flag. Note that the initial value of the delay flag is set to OFF.
In step 112, the elevator main body control unit 41 performs the delayed attachment confirmation car control as in step 103.

In step 113, the elevator main body control unit 41 refers to the attachment confirmation information, and whether or not there is no inspection tag 70 in all of the halls 20, in other words, of the hall 20 where the inspection tags 70 are desired to be attached in the attachment process. It is determined whether or not the check tag 70 has been removed from all.
In step 113, the elevator main body control unit 41 proceeds to step 119 when there are no inspection tags 70 in all the halls 20, and proceeds to step 114 when inspection tags 70 remain in at least one hall 20. .
In step 114, the elevator main body control unit 41 informs the monitoring device 75 that the inspection operation is not executed even if the inspection delay certification time has passed and the inspection tag 70 is left on the landing 20 at the monitoring center 80. To report.

In step 109, when the elevator body control unit 41 determines that the inspection end operation has been performed, the elevator body control car control is performed as in step 103 (step 115), and the process proceeds to step 116.
As described in step 103, when the attachment confirmation car control in step 115 is performed, the attachment detection apparatus 50 uses the information on the presence / absence of the inspection tag 70 at each landing 20 as attachment confirmation information. It is configured to output.

In step 116, the elevator main body control unit 41 refers to the attachment confirmation information, and whether or not there is no inspection tag 70 in all of the halls 20, in other words, for the hall 20 that is desired to attach the inspection tag 70 in the attachment process. It is determined whether or not the check tag 70 has been removed from all.
If the elevator main body control unit 41 determines in step 116 that at least one check tag 70 is left in the hall 20, the same flow as in step 105 is performed in step 117.

If the elevator body control unit 41 determines in step 117 that the attachment reconfirmation command has been input, it performs car control for attachment reconfirmation (step 118).
The car control for reconfirmation of the attachment here sets the floor having the landing 20 where the inspection tag 70 is detected as the destination floor, and each time the car 30 reaches the landing 20 of the set floor, The elevator door 28 is opened and a check signal is output when the elevator door 28 is fully opened.

If the elevator body control unit 41 determines in step 116 that there are no inspection tags 70 in all the halls 20, the elevator main body control unit 41 turns off the inspection mode (step 119).
When the inspection mode is turned off, the light emission control of the hall call button 23 flashed when the inspection mode is turned on is returned to the normal light emission control that emits light according to the operation of the hall call button 23. 75 which permits the report of the abnormality of the elevator main body 10 to the monitoring center 80 which has been rejected by 75. That is, turning off the inspection mode means returning the control of the elevator main body 10 to normal operation control performed when a general user uses it.

  In step 120, the elevator body control unit 41 stops and resets the time count of the timer 42 and ends the control.

Next, the operation of the attachment detection device 50 will be described with reference to the drawings.
FIG. 6 is a flowchart for explaining the operation of the elevator attachment detector according to the embodiment of the present invention.
In FIG. 6, steps 201 to 206 are denoted as S201 to S206 for convenience of explanation.

In step 201, the detection device control unit 57 determines whether or not the main inspection start operation has been executed.
If it is determined in step 201 that the main inspection start operation has not been executed, the detection device control unit 57 repeats step 201. If it is determined that the main inspection start operation has been executed, the detection device control unit 57 performs attachment inspection control before the main inspection (step 202).

Hereinafter, the attachment confirmation control before this inspection will be described.
FIG. 7 is a flowchart of the attachment confirmation control before this inspection, which is performed by the elevator landing attachment detection apparatus according to the embodiment of the present invention.
In FIG. 7, steps 301 to 306 are denoted as S301 to S306 for convenience of explanation.

In step 301, the detection apparatus control unit 57 determines whether or not a check signal has been received.
As described above in the operation of the elevator main body 10, the check signal is output every time the car 30 reaches the landing 20 and the elevator door 28 is fully opened after the main inspection start operation is executed.
If the detection device control unit 57 determines in step 301 that the check signal has not been received, step 301 is repeated.
In step 301, when the detection device control unit 57 determines that the check signal has been received, the detection device control unit 57 confirms the presence or absence of the check tag 70, and associates the confirmation result with the floor of the hall 20 where the car 30 is currently landing. Store (step 302).

  In step 303, the detection device control unit 57 determines whether or not the check tags 70 have been confirmed for all halls 20 (all desired halls 20) on the floor to which the check tags 70 are attached.

When the detection device control unit 57 determines in step 303 that confirmation of the check tag 70 has not been completed for all desired halls 20, the detection device control unit 57 returns to step 301 and has confirmed that the check tags 70 have been confirmed for all desired halls 20. If determined, the process proceeds to step 304.
In step 304, the detection device control unit 57 distributes attachment confirmation information, which is information on the presence / absence of the check tag 70 for each hall 20, to the elevator body control unit 41.

In step 305, the detection device control unit 57 determines whether or not an attachment reconfirmation command is input. If it is determined that an attachment reconfirmation instruction is input, the process returns to step 301.
When the attachment reconfirmation command is input, the elevator main body 10 performs the attachment reconfirmation car control. Therefore, in steps 301 to 304, the detection device controller 57 causes the car in the attachment reconfirmation car control. The presence / absence of the check tag 70 at the hall 20 on the floor where 30 is stopped is confirmed, and the attachment confirmation information is updated and transmitted.

If it is determined in step 305 that the attachment reconfirmation command has not been input, the detection device control unit 57 determines whether or not the inspection mode has been turned on (step 306).
In step 306, when the detection device control unit 57 determines that the inspection mode is not ON, the detection device control unit 57 returns to step 305. When the detection device control unit 57 determines that the inspection mode is ON, the pre-inspection attachment confirmation control is terminated. Migrate to

  In step 203, the detection apparatus control unit 57 determines whether or not the delay flag is turned on. When it is determined that the delay flag has been turned ON, the delayed attachment confirmation control (process) is performed (step 204).

The delayed attachment confirmation control will be described below.
FIG. 8 is a flowchart of the delayed attachment confirmation control performed by the elevator attachment detector according to the embodiment of the present invention.
In FIG. 8, steps 401 to 404 are denoted as S401 to S404 for convenience of explanation.
In FIG. 8, Steps 401 to 404 are the same as Steps 301 to 304 described above. That is, when the delay flag is turned ON, as described above, the elevator main body 10 starts the attachment control car control, and in conjunction with this, the detection device control unit 57 determines whether or not there is an inspection tag 70 in each hall 20. The attachment confirmation information is transmitted, and the attachment confirmation control at the time of delay is terminated.

In step 203, when the detection device control unit 57 determines that the delay flag is not ON, the detection device control unit 57 determines whether an inspection end operation has been performed (step 205).
In step 205, when the detection device control unit 57 determines that the inspection end operation has not been executed, the detection apparatus control unit 57 returns to step 203. When the detection device control unit 57 determines that the inspection end operation has been executed, post-inspection attachment confirmation control (process) is performed.

The post-inspection attachment confirmation control will be described below.
FIG. 9 is a flowchart of post-inspection attachment confirmation control performed by the elevator landing attachment detection apparatus according to one embodiment of the present invention.
In FIG. 9, steps 501 to 506 are denoted as S501 to S506 for convenience of explanation.

In FIG. 9, steps 501 to 505 are the same as steps 301 to 305.
In step 506, the detection device control unit 57 determines whether or not the inspection mode has been turned off. If it is determined that the inspection mode has not been turned off, the detection apparatus control unit 57 returns to step 505 and determines that the inspection mode has been turned off. After the inspection, the attachment confirmation control is finished.

Next, an inspection method for the elevator 1 using the attachment detection device 50 will be described.
FIG. 10 is a flowchart for explaining an elevator inspection method using the elevator landing fixture detection apparatus according to one embodiment of the present invention.

If the photographing means 51 is not in the car 30 in advance, it is attached in the car 30 in advance.
As shown in FIG. 10, in step 601, the worker performs an attaching process for attaching the inspection tags 70 to all the floors 20 on which the inspection tags 70 are desired to be attached.
In step 602, the operator performs a main inspection start operation.
At the same time as the main inspection start operation, the elevator main body control unit 41 performs car control for attachment confirmation. That is, control is performed in which the car 30 is sequentially landed on the landing 20 and the elevator door 28 is opened and closed. In conjunction with this, in the attachment detection device 50, the detection device controller 57 determines whether or not there is a reflecting material in the video data acquired by the imaging means 51 when the elevator door 28 is opened at each landing 20. Based on this, a pre-inspection attachment confirmation process for determining the presence or absence of the inspection tag 70 is performed. At this time, the attachment detection device 50 outputs attachment confirmation information regarding the presence / absence of the check tag 70 at each hall 20.

  The operator can confirm the attachment confirmation information by connecting a PC terminal to an output terminal provided on the car operation panel 33 for transmitting the attachment confirmation information to the outside.

In step 603, the attachment confirmation information is confirmed, and it is confirmed whether or not there is a landing 20 where the inspection tag 70 has been forgotten to be attached.
If it is determined in step 603 that there is a landing 20 for which the inspection tag 70 has been forgotten to be attached, the operator attaches the inspection tag 70 to the corresponding landing 20 (step 604). Further, in step 605, an attachment reconfirmation command operation is performed. To return to the flow of step 603.

  In step 603, the method for the operator to confirm that the check tag 70 is not forgotten to be attached is as follows. If there is no forgetting to attach the inspection tag 70, the elevator main body control unit 41 automatically turns on the inspection mode and starts the count of the timer 42. Then, with the fact that the inspection mode has been turned on, the operator confirms that he / she has not forgotten to attach the inspection tag 70 and carries out the main inspection work (step 606).

In step 607, the operator removes the inspection tags 70 from all the landings 20 to which the inspection tags 70 are attached.
In step 608, the operator performs an inspection end operation.
At the same time as the inspection end operation, the elevator main body control unit 41 performs car control for attachment confirmation. In conjunction with this, a post-inspection attachment confirmation step similar to the above-described pre-inspection attachment confirmation step is performed, and the attachment detection device 50 outputs attachment confirmation information.

In step 609, the worker confirms the attachment confirmation information, and confirms whether or not there is a landing 20 that has forgotten to remove the inspection tag 70.
In step 609, if the operator determines that there is a landing 20 that has forgotten to remove the inspection tag 70, in other words, if it is determined that the inspection tag 70 remains on the landing 20 that is desired to be attached in the attachment process, The inspection tag 70 is removed from the landing 20 (step 610). Further, in step 611, an attachment reconfirmation command operation is performed, and the flow returns to step 608.

  In step 609, when the operator determines that there is no landing 20 for which the check tag 70 has been forgotten to be removed, the inspection work for the elevator 1 is finished.

  In the above elevator inspection method, it is assumed that the operator performs the inspection end operation in step 608. However, in step 608, the operator finishes the inspection operation without performing the inspection end operation. In other words, when the count time of the timer 42 has passed the inspection delay certification time, the following steps are automatically performed.

  The passage of the inspection delay authorization time corresponds to step 111. In the elevator main body 10, the elevator 30 is sequentially controlled by causing the car 30 to land on the landing 20 where the inspection tag 70 is desired to be attached. A car control process for checking the attachment at the time of delay is performed. In conjunction with this, the attachment detection device 50 causes the detection device controller 57 to determine the presence or absence of the inspection tag 70 based on the presence or absence of the reflective material 52 in the video data acquired by the imaging means 51, and the attachment A delayed attachment confirmation process for outputting confirmation information is performed.

If the elevator main body control unit 41 determines from the judgment result of the presence or absence of the check tag 70 of each hall 20 that is performed in the delayed-fitting attachment confirmation process, the elevator 1 is inspected. A step of outputting information indicating that work has not been completed to the monitoring center 80 is performed.
Further, in the delayed attachment confirmation process, when there is no attachment on the landing 20, the elevator body control unit 41 performs a process of automatically returning the control of the elevator body 10 to the normal operation mode.

  The elevator landing fixture detection apparatus 50 according to the present invention includes an imaging means 51 provided in the car 30 with an area including the car entrance 31 as an imaging area, and via the hall entrance 21 when attached to the landing 20. The presence or absence of the check tag 70 in the video data photographed by the photographing means 51 under the condition that the reflector 52 provided at the site of the check tag 70 facing the hoistway 12 and the elevator door 28 are in the open state. And a detection device control unit 57 that judges as follows.

  Therefore, the attachment detection device 50 can check the presence or absence of the inspection tag 70 when the car 30 is landed on each landing 20 with respect to the landing 20 where the inspection tag 70 is installed and the elevator door 28 is opened. It becomes possible. That is, the light is always reflected by the reflecting material 52, and the detection device control unit 57 has a portion in the image acquired by the photographing unit 51 that is much brighter than the surroundings. It can be determined that the check tag 70 is provided at the hall 20.

  For example, as described above, when the worker performs the inspection work, when the inspection end operation is performed, the attachment detection device 50 is configured to confirm the presence or absence of the inspection tag 70. Even if the worker has forgotten to remove the inspection tag 70, the worker can confirm that the inspection tag 70 has been forgotten to be removed simply by confirming the determination result of the presence or absence of the inspection tag 70 by the attachment detection device 50. It is no longer possible to return as if the inspection work of the elevator 1 has been completed without forgetting to remove it.

Further, the attachment detection device 50 is configured to determine the presence or absence of the inspection tag 70 from the video imaged by the imaging unit 51 when the light emitting unit 55 emits light.
Thus, even if an object that shines very brightly toward the landing entrance 21 is provided on the landing 20 side, the detection device control unit 57 reliably determines that this object is mistaken for the inspection tag 70. Is prevented. However, the detection effect of the check tag 70 is not lost even if the light emitting means 55 is always lit.

Further, although the identification means has been described as the reflective material 52, the identification means is not limited to the reflective material 52, and may be an identification mark having a predetermined shape such as a QR code or characters. In this case, in particular, the light emitting means 55 should always illuminate the interior of the car 30, and when the detection device control unit 57 determines that there is an identification mark in the video data acquired by the photographing means 51, What is necessary is just to comprise so that it may judge that the check tag 70 is attached to the landing 20 where the car 30 landed.
By using the identification means as an identification mark, the identification means can be configured at a lower cost than that using the reflecting material 52.

  In addition, the elevator 1 inspection method using the elevator attachment detection device 50 includes a removal step of removing the inspection tag 70 after the completion of the inspection work, and a landing 20 where the inspection tag 70 is desired to be attached after the removal step. On the other hand, a step of performing control for sequentially landing the car 30 and opening and closing the elevator door 28, and presence / absence in the video data acquired by the photographing means 51 when the elevator door 28 is opened at each landing 20 If it is determined that the inspection tag 70 is left on the landing 20 from the post-inspection attachment confirmation process for causing the detection device controller 57 to determine the presence or absence of the inspection tag 70 and the determination result of the presence or absence of the inspection tag 70 And a step of removing the check tag 70 left on the hall 20.

  Therefore, even if there is a landing 20 in which the inspection tag 70 is forgotten to be removed in the process of removing the inspection tag 70, the determination result of the presence / absence of the inspection tag 70 in the post-inspection attachment confirmation process performed thereafter is confirmed. As a result, the operator recognizes that he / she has forgotten to remove the inspection tag 70, and can thus prevent forgetting to remove the inspection tag 70.

  Further, in the elevator 1 inspection method, the operation of starting the timer 42 immediately before the main inspection process and the count time of the timer 42 are not performed for the end of the main inspection work of the elevator for the inspection delay certification time. A car control process for checking attachments at a time of delay, in which control is performed such that the car 30 is sequentially landed and the elevator door 28 is opened and closed with respect to the landing 20 where the inspection tag 70 is desired to be attached in the attaching process. Each time the elevator door 28 is opened during the delayed attachment confirmation car control process, the delayed attachment confirmation process is performed so that the detection device controller 57 determines the presence or absence of the inspection tag 70 at each landing 20. It has become. Furthermore, when it is determined from the determination result of the presence or absence of the inspection tag 70 in the delayed attachment confirmation process that the inspection tag 70 remains on the landing 20, information indicating that the inspection work of the elevator 1 has not been completed is output. A process is performed.

  Therefore, if the output destination of the information indicating that the inspection work of the elevator 1 has not been completed is set in the management center where the administrator of the elevator 1 is located, the worker leaves the inspection tag 70 for some reason, If left unattended, the manager of the elevator 1 can respond quickly and prevent the normal operation of the elevator 1 from being stopped unnecessarily.

  Furthermore, the inspection method of the elevator 1 is a method in which the control of the elevator main body 10 is switched to the inspection mode prior to the main inspection process, and when there is no inspection tag 70 on the landing 20 in the delayed attachment confirmation process. The elevator main body control unit 41 includes a step of automatically returning the control of the elevator main body 10 to the normal operation mode.

  Here, when the operator finishes this inspection work and removes the inspection tags 70 at all the landings 20, there is no problem in returning the elevator 1 to normal operation. By controlling as described above, even if the operator who finished this inspection work and removed the inspection tag 70 forgot to return the operation mode of the elevator body 10 to the normal operation mode, Since the elevator body 10 is automatically returned to the normal operation mode when the inspection delay authorization time has elapsed, it is possible to prevent the normal operation of the elevator 1 from being stopped unnecessarily.

Although the present invention has been described as detecting the inspection tag 70 as an attachment, any attachment other than the inspection tag 70 may be detected as long as the attachment is attached so as to protrude to the landing entrance 21. Is also applicable.
Further, in step 113 and step 114, when the inspection end operation is not effective even after the inspection delay authorization time has passed and the inspection tag 70 is left on the landing 20, the notification to the monitoring center 80 is sent to the elevator. Although the main body control unit 41 has been described as being performed, the detection device control unit 57 is configured to monitor the count of the timer 42 and further determine the presence / absence of the check tags 70 at all desired landings. Information may be reported to the monitoring center 80 according to the above.
