  Embodiments according to the present invention will be described below in detail with reference to the drawings. The dimensions, shapes, and the like described below are examples for explanation, and can be appropriately changed according to the specification of the elevator abnormal stop notification system.

  Below, the same code | symbol is attached | subjected to the same element in all the drawings, and the overlapping description is abbreviate | omitted. In the description in the text, the symbols described before are used as necessary.

  FIG. 1 is a configuration diagram of an elevator system 10 including an elevator abnormal stop notification system 20. The elevator system 10 includes a hall 12, a car 15 that moves up and down in the hoistway 13 in a building 14 having the hoistway 13, and an abnormal stop notification system 20 for the elevator.

  Here, in the elevator system 10, a state is shown in which the car 15 is stopped at the normal landing position with respect to the fifth floor with the fifth floor of the building 14 as the target floor. FIG. 1 shows the XYZ directions. The X direction indicates the direction from the landing 12 toward the hoistway 13, the Y direction indicates the direction from the right to the left when the landing door 16 is viewed from the landing 12, and the Z direction indicates that the car 15 passes through the hoistway 13. The direction from the lower side to the upper side is shown.

  The hall 12 is an elevator hall provided on each floor in the building 14, and has a call button for calling the car 15 on that floor. The hall 12 on each floor may be referred to as a landing floor. A landing door 16 is provided at the landing 12. The landing door 16 is a door that opens and closes in conjunction with the opening and closing of the car door 17 when the car 15 reaches the landing 12, thereby allowing the user to enter and exit the car 15.

  The hoistway 13 is a space penetrating the building 14 from the top floor to the bottom floor, and the car moves up and down in this space. A floor mark indicating each landing floor is attached to the landing side wall surface 18 of the hoistway 13. The floor mark is preferably attached to at least one of the upper part and the lower part of the landing door 16 or the side part.

  The car 15 is a moving car in which a user or the like can be placed in the internal space. The car 15 has a destination registration operation panel (not shown) in which a user can enter a desired floor. FIG. 1 shows a state where the destination floor is the fifth floor and the car 15 is landed on the fifth floor. The car 15 is provided with a car door 17. The car door 17 is not particularly limited, and a single door, a double door, or the like can be used as appropriate. The door is provided on the platform 12 side of the car 15 and is used by a user to get on and off the car 15. The operation of the car 15 and the opening and closing of the car door 17 are performed by a control unit (not shown) of the elevator system 10 in normal operation. The normal operation means normal operation except when the elevator operation is stopped due to an elevator failure or an emergency stop due to an earthquake fire.

  The elevator abnormal stop notification system 20 compares the stop image with the normal landing image when the car 15 moving up and down in the hoistway 13 stops, determines whether there is a difference between the images, and the difference is recognized. In this case, the car is abnormally stopped, and the abnormal stop is detected when the abnormal stop is detected. The abnormal stop notification system 20 includes an imaging unit 22, a storage unit 24, a detection notification unit 26, a recovery unit 28, a notification output device 30, and a monitor 32.

  The imaging unit 22 is a camera attached to the car 15 facing the landing side wall surface 18 of the hoistway 13. It has a function of capturing the landing side wall surface 18 in the hoistway 13 when the car 15 is stopped and acquiring the captured image as a stop-time image. Further, it has a function of acquiring the floor mark attached to the landing side wall surface 18 as the floor mark image when the car 15 is operating. The imaging unit 22 can use a commercially available camera. Examples of such a camera include an image processing camera, a surveillance camera, a photographing camera, and an infrared camera. Among these, it is preferable to use an image processing camera. An image acquired by the image processing camera can be measured by quantifying coordinates, shape, dimensions, color, and the like from the image, and the image can be analyzed based on these measured values. The abnormal stop notification system 20 can compare the normal landing image and the stop image as image analysis.

  Since the imaging unit 22 captures an image in the dark hoistway 13, it may be preferable to use an image processing camera equipped with an infrared night vision function. In some cases, it is preferable to mount a light emitting unit on the imaging unit 22. The light emitting unit is illumination that can emit strong light during imaging. The light emitting unit can be built in or externally attached to the imaging unit 22. When the light emitting unit is not mounted, illumination may be turned on in the hoistway 13 so that a clear stop image can be obtained. As illumination, for example, LED illumination can be used. When lighting such as lighting is turned on in the hoistway 13, a clear stop-time image is obtained, and in some cases, the user can pay attention to his / her feet by lighting from the hoistway 13.

  In addition, a plurality of imaging units 22 are preferably installed. For example, it is preferable that the imaging units 22 are installed at an upper part and a lower part of the car 15. By installing a plurality of imaging units 22 in this way, for example, even when one unit fails, images can be acquired from other imaging units 22 and compared. In addition, it is preferable that the car 15 is installed at the upper and lower parts of the car 15 because a similar image may be obtained even if a plurality of cars are installed at adjacent positions, and the position of the landing side wall surface 18 may not be clearly imaged. This is because it is considered. When the above problem is solved, the imaging unit 22 may be a single unit.

  The memory | storage part 24 is a memory which memorize | stores the image at the time of normal landing which imaged the landing side wall surface 18 in the hoistway 13 when landing normally at the normal landing position of a landing floor for every landing. Further, the floor mark images acquired by the imaging unit 22 can be stored while being sequentially updated. The storage unit 24 preferably stores a stop-time image in addition to a normal landing image.

  The normal landing image is a reference image in a stopped state in which the car 15 has landed on the landing floor. Therefore, separately, the car 15 is imaged while stopping at the correct landing position for each floor, and this is used as a normal landing image. Therefore, there is a normal landing image for each floor, and in principle, the normal landing image is stored in the storage unit 24 for a predetermined period.

  Here, the normal landing image will be described. FIG. 2 is a diagram illustrating a relationship between the landing side wall surface 18 and the imaging unit 22. FIG. 2 shows a state in which a normal landing image is captured when the car 15 is normally landed on the fifth floor, with the landing side wall surface 18 viewed from the hoistway 13 on the right side and the landing side wall surface 18 on the right side. Correspondingly, the imaging unit 22 provided on the car 15 when the car 15 is viewed from the side surface along the Y direction is shown on the left side. For example, it is assumed that the imaging units 22 are provided at the upper and lower portions of the car 15. An image A imaged by the imaging unit 22 provided at the upper part of the car 15 and an image B imaged by the imaging unit 22 provided at the lower part of the car 15 are obtained as normal landing images A and B, respectively.

  On the other hand, the stop-time image is picked up every time the car 15 stops during normal operation of the elevator. The stop-time image is temporarily stored for comparison as to whether or not the stop position of the car 15 is the same as the normal landing position. Note that when the control is performed to restore the stop position to the normal landing position because the stop position is deviated from the normal landing position, the restoration can be performed using the image at the time of stop. In that case, every time the position of the car 15 is changed, it is preferable to compare the image at the time of the stop after the restoration with the image at the time of normal landing.

  The detection notification unit 26 notifies at least the landing 12 of the abnormal stop when the abnormal stop of the car 15 is detected based on the comparison between the stop time image and the normal landing image. Here, the comparison is performed based on the measurement values related to the image obtained from the stop-time image and the normal landing image. Therefore, if it is determined that there is a difference between the stop-time image and the normal landing image as a result of comparison, it is determined that an abnormal stop of the car 15 has been detected, and the user has detected that the car 15 has stopped abnormally, or An audio display such as a time step warning can be transmitted to the notification output device 30. Further, the detection notification unit 26 preferably reads from the storage unit 24 the floor mark image updated immediately before the car 15 stops and the normal landing image of the landing floor corresponding to the floor mark. In this way, the detection notification unit 26 determines whether the car 15 is in a correct state based on the comparison between the normal landing image and the stop image corresponding to the floor mark of the floor mark image updated immediately before the car 15 stops. Abnormal stop can be detected correctly.

  The restoration unit 28 may restore the car 15 from the abnormal stop position to the normal landing position so as to eliminate the difference in the positions of the corresponding portions of the landing side wall surface 18 in the stop-time image and the normal landing image. it can. In order to eliminate the difference, it is preferable to make the difference equal to or less than a predetermined threshold at a certain point on the coordinate plane of the image obtained by the imaging unit 22, and it is more preferable to make the difference approximately the same. In addition, the recovery unit 28 can transmit a voice display to the notification output device 30 in order to notify the hall 12 at least that the recovery is performed or has been completed.

  The notification output device 30 is provided in the hall 12 and transmits information by electronic voice having a predetermined content to the user of the hall 12. For example, a speaker or the like can be used. The information is a message or the like for guiding the user's action output from the detection notification unit 26 or the recovery unit 28. Further, the notification output device 30 may be provided with an LED lamp or the like, and the LED lamp may be turned on so as to call attention during voice display.

  The monitor 32 is installed in the hall 12 and outputs a stop-time image. The user can know the abnormal stop of the car by looking at the stop-time image output to the monitor.

  The functions of the detection notification unit 26 and the recovery unit 28 can be realized by executing software. Specifically, it can be realized by executing an elevator operation control program.

  Next, the effect | action of the said structure is demonstrated in detail using the block diagram shown in FIG. 3, and the block diagram of the elevator system 10 at the time of the abnormal stop of the cage | basket | car 15 shown in FIG. FIG. 3 is a flowchart for comparing an image when the car 15 is stopped and a normal landing image during normal operation and notifying the user of an abnormal stop when the car 15 is abnormally stopped. FIG. 4 is a configuration diagram of the elevator system 10 when the car 15 at the normal landing shown in FIG. 1 abnormally stops.

  The initial state is a normal operation in which the car 15 moves up and down in the hoistway 13 (S10). A floor mark indicating the landing floor is attached to the landing side wall surface 18 in the hoistway 13. When the car 15 is operating, the imaging unit 22 sequentially acquires floor mark images (S12). For example, when the car 15 rises, the floor marks attached to the landing side wall surface 18 are acquired in the order of 1, 2, 3... , 3... The acquired floor mark images are stored in the storage unit 24 while being sequentially updated.

  The car 15 stops according to the call button pressed by the user at the landing 12 (S14). FIG. 4 shows a state in which the car 15 stops at a position other than the correct landing position while the fifth floor is the target floor. Indicated. The car 15 is stopped at a position below ΔH from the normal landing position that should be stopped. This ΔH corresponds to a step ΔH between the landing floor 12a and the car floor 15a. When the car 15 stops, the imaging unit 22 acquires a stop-time image obtained by imaging the landing side wall surface 18 (S16).

  FIG. 5 is a diagram illustrating the relationship between the landing side wall surface 18 and the imaging unit 22 in FIG. 4. FIG. 5 shows a state in which a stop-time image is picked up in the same manner as the normal landing image shown in FIG. Here, an image C picked up by the image pickup unit 22 provided in the upper part of the car 15 and an image D picked up by the image pickup part 22 provided in the lower part of the car 15 are obtained as stop time images C and D, respectively.

  Next, when the car 15 stops, the detection notification unit 26 reads from the storage unit 24 a normal landing time image of the landing 12 corresponding to the floor mark image of the floor mark image updated immediately before the car 15 (S18). The storage unit 24 stores a normal landing image obtained by imaging the landing side wall surface 18 in the hoistway 13 when the car 15 has normally landed for each landing 12. Images A and B at the time of landing are read out.

  The detection notification unit 26 compares the normal landing images A and B of the landing 12 corresponding to the floor mark image updated immediately before the car 15 stops with the stop images C and D acquired in S16. Perform (S20). Here, the normal landing image A in FIG. 2 acquired by the imaging unit 22 provided in the upper part of the car 15 is compared with the stop image C in FIG. 5, and the imaging provided in the lower part of the car 15 is performed. 2 is compared with the normal landing image B of FIG. 2 and the stop image D of FIG. Since the places to be compared are places corresponding to each other on the landing side wall surface 18, two coordinate axes that are orthogonal to each other on the plane of the stationary image and the normal landing image, the Y axis, and the Z axis are defined, and the coordinates Y and Z are defined. A comparison is made as to whether or not there is a difference in the measurement values relating to the image at the set point (Y, Z).

  In S20, the normal landing image acquired by the imaging unit 22 provided on the upper part of the car 15 and the stop image are compared, and it is determined that there is no difference in the measured values at points corresponding to each other on the coordinate plane, and When the normal landing image acquired by the imaging unit 22 provided at the lower part of the car 15 and the stop image are compared, and it is determined that there is no difference in the measured values at certain points corresponding to each other on the coordinate plane. The stop position of the car 15 is assumed to be a normal landing position, and the car 15 proceeds to S28 and performs normal operation.

  However, comparing the normal landing image A with the stop image C in FIG. 6, it is confirmed that the normal landing image A has a floor mark at a certain point on the coordinate plane. It is not confirmed that the hour image C has a floor mark, or the color tone derived from the landing door 16 is different at a certain point. In such a case, in S20, the detection notification unit 26 determines that there is a difference. In addition, when comparing the normal landing image B and the stop image D in FIG. 6, it is confirmed that both the normal landing image B and the stop image D are marked with floor marks. The points on the coordinate axes are different. Also in this case, the detection notification unit 26 determines that there is a difference in the measured value at a certain point on the coordinate plane.

  Next, by comparing the images shown in FIG. 6, it is possible to measure how much level difference ΔH the stop position of the car 15 has from the normal landing position. Based on the result of this measurement, the car 15 is regarded as an abnormal stop that has not stopped at the normal landing position, and the abnormal stop of the car 15 is detected. As points to be compared, points that are easy to compare, such as the upper line of the landing door 16, the line of the landing floor 12a, and the position of the floor mark, can be used as appropriate.

In FIG. 6, the difference between the point on the upper line of the landing door 16 existing on the Z axis of the normal landing image A and the point on the upper line of the landing door 16 existing on the Z axis of the stopped image C is shown. This corresponds to the step ΔH. If the level difference ΔH is equal to or greater than a predetermined threshold value ΔH _{0, the} level difference ΔH is set as a level where the user may fall over. For example, when the threshold value ΔH ₀ is predetermined as 10 cm, an abnormal stop of the car 15 is detected when the step ΔH is 10 cm or more.

  When detecting the abnormal stop of the car 15, the detection notification unit 26 notifies the landing 12 of the abnormal stop of the car 15 (S22). A voice display is output from the detection notification unit 26 to the notification output device 30 provided at the hall 12. From the notification output device 30 at the hall 12, "the car has moved off the normal position and stopped. It is dangerous even if the door opens. Please don't get in. " In addition, it may be preferable that an announcement notifying an abnormal stop is output as an image display in addition to a sound display. The detection notification unit 26 outputs a stop-time image to the monitor 32 provided in the hall 12. The user of the hall 12 can also know the abnormal stop of the car 15 by the image display.

  At the stop position of the car 15 as shown in FIG. 4, there is a step ΔH between the car floor 15a and the landing floor 12a. For example, if the step ΔH is about 60 cm or less, the car door 17 opens. The landing door 16 that interlocks with the car door 17 may also open. Even when the landing door 16 is opened in a state in which a level difference is larger than expected, it is preferable that the announcement is made on the initiative so as to ensure the safety of the user.

  After notifying that the restoration is performed when performing restoration control, the restoration unit 28 operates the car 15 to restore the car 15 to the normal landing position (S24). Here, a voice display is output from the recovery unit 28 to the notification output device 30 provided at the hall 12. At the hall 12, from the notification output device 30, “the car has deviated from the normal position and stopped. Please wait. " In addition, it may be preferable that an announcement notifying that the restoration is performed is output as an image display in addition to a sound display.

  As a recovery method, it is preferable to operate the car 15 so that the image at the time of stoppage is the same as the image at the time of normal landing. For this purpose, it is preferable that the measurement value at a certain point on the coordinate plane is the same between the stop-time image and the normal landing image. This corresponds to eliminating the step ΔH. During the restoration, the opened car door 17 and the landing door 16 are preferably closed, but may remain open in some cases. When the car door 17 and the landing door 16 are not engaged and are controlled to be opened and closed independently, it is preferable that the restoration unit issues a command to close the car door 17 and the landing door 16 respectively.

  The recovery unit 28 notifies the hall 12 that normal operation is resumed when the recovery is completed (S26). A voice display is output from the restoration unit 28 to the notification output device 30 provided in the hall 12. At the hall 12, the notification output device 30 indicates that the car has returned to the normal landing position. Normal operation is resumed. Announcement flows. After the notification, the process proceeds to S28 and normal operation is resumed. Further, in some cases, it is preferable that the announcement notifying the resumption output an image display in addition to the audio display. The restoration unit 28 outputs the stopped image after restoration to the monitor 32 provided in the hall 12. The user of the landing 12 can also know that the car 15 has been restored to the normal landing position by image display.

  As described above, according to the elevator abnormal stop notification system, when the car 15 stops, the stop-time image obtained by imaging the landing side wall surface 18 in the hoistway 13 is acquired, and when the landing on the landing 12 is normally performed. A normal landing image obtained by imaging the landing side wall surface 18 in the hoistway 13 is stored for each landing 12, and an abnormal stop of the car 15 is detected based on a comparison between the stopping image and the normal landing image. At least the platform 12 can be notified of an abnormal stop.

  As another embodiment, a notification output device 30 provided in the hall 12 having the above-described configuration can be provided in the car 12. Thereby, the abnormal stop of the car 15 can be conveyed to the users in the car 12 by voice display. As an example, it is preferable that the announcement notifying the abnormal stop flows in the car 15 in the same manner as being output from the detection notification unit 26 to the notification output device 30 provided in the hall 12. For example, a speaker may be provided in the car 15 and an announcement such as “The car has stopped from a normal position and stopped. Do not get off to the landing even if the door opens” may be used.

  Moreover, it is preferable that the announcement notifying the abnormal stop display an image in the car 15 in addition to the voice display. Such a monitor for image display is provided in the car 15 in the same manner as the notification output device 30. The detection notification unit 26 outputs a stop-time image similar to that output to the monitor 32 provided in the hall 12 to a monitor provided in the car 15. Thereby, the user in the car 15 can know the abnormal stop of the car 15.
