Description

  Embodiments described herein relate generally to an elevator display device provided at a landing.

  An operation button is installed in the elevator platform, and a landing call is registered by pressing the operation button. Usually, this operation button is fixedly installed on the wall surface of the landing at a position of about 1,200 mm from the floor surface. In addition, in the case of a wheelchair-specific elevator, an operation button dedicated to the wheelchair user is separately provided at a position lower than the operation button for the general user so that the user can operate the button while sitting in the wheelchair.

  In recent years, a so-called “touch panel type” in which a touch sensor is attached to a flat display panel such as an LCD (Liquid Crystal Display) for the purpose of improving design and operability or installing a destination floor registration device at a landing. It is considered to install a “display device” instead of an operation button.

  However, when the two touch panel display devices described above are installed for a general user and a wheelchair user, the cost is increased, and an installation space must be secured. In addition, when only one unit is used, it is required to be installed at a low position according to the wheelchair user. However, since a display such as an LCD has a narrow viewing angle, there is a drawback that the display contents cannot be visually recognized unless there is a screen at the position of the user's line of sight. For this reason, when it installs in a low position according to a wheelchair user, it will force a general user to bend and operate, and there exists a problem that operativity falls remarkably.

  Therefore, there is a need for an elevator display device that can easily register calls to general users and wheelchair users without degrading operability at the landing.

  The elevator display device according to the present embodiment is an elevator display device that is installed at a landing and has a function of registering a call by a user's operation, a flat display having a touch sensor on a screen, and the flat display. A support mechanism that rotatably supports the display on the wall surface of the platform and a control device that adjusts an inclination angle of the flat display via the support mechanism are provided.

  Further, a hinge mechanism 24 incorporating a motor 23 and a mounting member 25 are provided at the upper end of the box-shaped main body of the display device 20 as a support mechanism for supporting the display device 20. As shown in FIG. 3, the display device 20 is rotatably attached to a wall surface 18 near a landing door (not shown) of the landing 17 via a hinge mechanism 24.

  The mounting position of the display device 20 is based on the height of the wheelchair user, and the initial position is determined so that the line of sight of the wheelchair user is at the center of the screen of the flat display 21. The solid line in FIG. 3 is the initial position, and the screen of the flat display 21 is substantially flush with the wall surface 18.

  In addition, a small camera 26 for photographing a user is installed near the upper center of the screen of the flat display 21. The height of the user is estimated based on the image taken by the camera 26, the flat display 21 is rotated via the hinge mechanism 24 according to the estimated height, and the inclination angle of the flat display 21 is adjusted. Is done.

  FIG. 4 is a diagram illustrating the relationship between the display device 20 and the control device 30.

  The control device 30 is provided as a display controller on the back surface of the display device 20. In addition to display control of the flat display 21 and input control of the touch sensor 22, the control device 30 has a function of adjusting the angle of the flat display 21 by driving control of the motor 23 built in the hinge mechanism 24 here.

  Specifically, a display output signal line 41, a touch sensor input signal line 42, a camera input signal line 43, and a motor control signal line 44 are connected between the display device 20 and the control device 30. Further, an elevator LAN signal line 45 is connected between the elevator control device 16 and the control device 30 shown in FIG.

  The control device 30 includes a display control unit 31, a touch sensor detection unit 32, a communication control unit 33, a camera image analysis unit 34, a height estimation unit 35, a motor drive unit 36, and a registration control unit 37.

  The display control unit 31 performs data display control on the flat display 21. The touch sensor detection unit 32 detects the position on the screen touched by the user from the signal of the touch panel 22 attached to the flat display 21. The communication control unit 33 performs transmission / reception control of data with the elevator control device 16, such as reception processing of display data given to the display control unit 31, transmission processing of a call registered in the registration control unit 37, etc. I do.

  In addition, the camera image analysis unit 34 analyzes an image captured by the camera 26 to detect the presence / absence of the user and, when there is a user, detects the position of the user's face. The height estimation unit 35 estimates the height of the user from the position of the user's face on the image detected by the camera image analysis unit 34. The motor drive unit 36 adjusts the tilt angle of the flat display 21 by driving the motor 23 according to the height of the user estimated by the height estimation unit 35.

  The registration control unit 37 performs call registration control in accordance with a touch operation on the screen of the flat display 21. The registration control unit 37 registers a call for switching to a special operation when the user estimated by the height estimation unit 35 is equal to or less than a preset threshold value. The “special operation” is a driving operation for a wheelchair user. Specifically, the opening / closing speed of the door is made slower than usual.

Next, the operation of the display device 20 will be described.
FIG. 5 is a flowchart showing the operation of the display device 20. Note that the processing shown in this flowchart is executed by the control device 30 which is a display controller of the display device 20.

  In the landing 17, images taken by the camera 26 are continuously given to the control device 30 with the display device 20 in the initial position. In the control device 30, when the captured image of the camera 26 is acquired, the captured image is analyzed by the camera image analysis unit 34 (step S11), and the presence or absence of the user is detected (step S12). Specifically, a user who exists within a predetermined distance from the front surface (flat display 21) of the display device 20 and stays there for a certain time or more is detected by image analysis.

  When the user is detected (Yes in step S12), the control device 30 turns on the flat display 21 through the display control unit 31 and displays a predetermined registration screen (step S13).

FIG. 6 shows a display example of the registration screen.
51 and 52 are landing call buttons, 51 is a button for designating an upward direction, and 52 is a button for designating a downward direction. 53 is an indicator, and the present driving direction and floor of the car 12 are displayed.

  Here, the control device 30 estimates the height of the user through the height estimation unit 35 (step S14). Specifically, the height of the user is estimated from the relationship between the position of the face and the angle of view of the camera 26 by detecting the position of the user's face from the image taken by the camera 26. It should be noted that the technique for authenticating a face in a captured image is general, and detailed description thereof is omitted here.

7 and 8 show specific examples of height estimation.
FIG. 7 is an example of an image 61 obtained by photographing a general user having an average height with the camera 26. The captured image 61 is scanned in the horizontal direction, and the height of the user is estimated from the position L1 of the user's face 62. FIG. 8 is an example of an image 63 obtained by photographing a wheelchair user with the camera 26. The captured image 63 is scanned in the horizontal direction, and the height of the user is estimated from the position L2 of the user's face 63.

  L0 is a reference position for determining whether or not the user is a wheelchair user. If the position of the user's face on the image is less than or equal to this reference position L0, the wheelchair user (or a child whose height is 1,200 mm or less). ).

  When the height of the user is estimated, the control device 30 drives the motor 23 through the motor drive unit 36 and adjusts the inclination angle of the flat display 21 according to the estimated height (step S15). . In this case, as shown by a dotted line a in FIG. 3, the inclination angle of the flat display 21 is adjusted so that the line of sight when the user looks at the flat display 21 is at the center of the screen.

  Thereby, even if a general user does not bend, he can easily visually recognize the screen of the flat display 21 and can perform call registration by touching a button or the like displayed on the screen.

  Here, when the user touches the screen of the flat display 21 (Yes in step S16), the touch position is detected by the touch sensor detection unit 32, and the corresponding processing is performed based on the positional relationship with the currently displayed item. It is executed (step S17). For example, if the user touches the landing call button 51 in FIG. 6, an upward landing call is registered.

  In addition, when the height estimated in step S14 is equal to or less than the reference position L0 set in advance and is determined to be a wheelchair user (Yes in step S18), to switch to a driving operation for a wheelchair user. Are automatically registered (step S19).

  The control device 30 transfers the call information registered by the registration control unit 37 to the elevator control device 16 via the communication control unit 33 (step S20). As a result, the elevator control device 16 makes the car 12 respond based on the call information received from the control device 30.

  In this case, if the special call is registered, the elevator control device 16 may set the door opening / closing speed slower than usual when the car 12 reaches the floor as a driving operation for wheelchair users. , Such as extending the door opening time than usual. Further, considering that the child is not a wheelchair user but a child, the contents displayed on the indicator are all changed to hiragana.

  If no screen touch is detected in step S16, or if a user is detected in the captured image after call registration (Yes in step S21), the process returns to step S13 and flat again. The angle of the display 21 is adjusted.

  If no user is detected in the captured image after call registration (No in step S21), the control device 30 returns the flat display 21 to the initial position through the motor drive unit 36 (step S22), and Then, the flat display 21 is turned off through the display control unit 31 (step S23).

  In this way, when the user is not present, the flat display 21 is returned to the initial position and retracted into the wall surface 18, thereby preventing people, carts, luggage, etc. passing through the landing 17 from hitting the flat display 21. In addition, power consumption can be suppressed by turning off the flat display 21 when there is no user.

  In the above embodiment, as a general landing call registration device, a screen having landing call buttons 51 and 52 and an indicator 32 as shown in FIG. 6 is displayed on the flat display 21 of the display device 20. The display device 20 may be used as a landing destination floor registration device taking advantage of the touch panel type. The “destination destination floor registration device” is a device for registering the user's destination floor at the landing 17.

  9 and 10 show an example in which the display device 20 is used as a landing destination floor registration device. FIG. 9 shows an example of a destination floor registration screen displayed on the flat display 21 of the display device 20, and FIG. 10 shows an example of a guidance screen displayed on the flat display 21 after destination floor registration.

  As shown in FIG. 9, the destination floor registration screen 71 includes a destination floor registration area 72, a destination floor selection area 73, a destination floor determination area 74, and a destination floor correction area 75. The destination floor selection area 73 is provided with numeric buttons from “0” to “9”.

  When the user touches these numeric buttons and inputs an arbitrary number of floors, the number of floors is displayed in the destination floor registration area 72. If the user touches the destination floor determination area 74 in this state, the number of floors is registered as the destination floor, and information on the destination floor is transferred to the elevator control device 16. If the user incorrectly inputs the number of floors, the floor number displayed in the destination floor registration area 72 is cleared by touching the destination floor correction area 25, and the registration operation is performed again. Can do.

  When the elevator control device 16 receives the destination floor information from the display device 20, the elevator control device 16 selects an elevator that is most suitable for the destination floor and directs it to the floor. In the example of the guidance screen 76 of FIG. 10, in the group management system having elevators (cars) of Units A to D, guidance is given when the elevator of Unit D is assigned to the call registration on the 10th floor as the destination floor. Show.

  Thus, even when the display device 20 is used as a landing destination floor registration device, the inclination angle of the flat display 21 is automatically adjusted according to the height of the user as described above, so that the general user does not bend. In both cases, it is possible to confirm the display contents and perform registration.

  As described above, according to the present embodiment, there is provided an elevator display device that can easily register calls to general users and wheelchair users without degrading operability at the landing.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
