Description

  The present invention relates to a guidance device that provides various types of information to elevator users, and in particular, guidance of an elevator hall that guides the operating status of elevators to users waiting for an elevator car in the elevator hall on each floor. Relates to the device.

  In an elevator hall that is provided on each floor of the building and has an entrance for an elevator car, a hall indicator is provided as a function to inform the users who are waiting for the elevator car at the elevator hall on this floor. , Lanterns, announcements, etc. For example, the hall indicator mounted on the top or side of the door displays the elevator car operation information, the lantern informs by flashing that the elevator car is about to land, and the announcement provides the elevator operation information by voice. .

An example of this type of elevator hall guiding apparatus is disclosed in Patent Document 1. In the “elevator device” disclosed in Patent Document 1, elevator operation information is projected onto an elevator (car) door by an irradiation device installed on the ceiling of the elevator hall. In general, elevator operation information refers to normal operation of the elevator during normal operation, control operation in the event of an earthquake, emergency operation with a charger in the event of a power failure, etc., and each floor (floor) of the car during these operations , Landing state by door blinking, landing state by flashing lantern, etc. are also included.
JP 2001-130845 A

  Conventionally, in order for a user to obtain elevator operation information, information displayed on a hall indicator, blinking of a lantern, and guidance by announcement have been required.

  The information displayed on the hall indicator is only the operation information such as the current position of the elevator car, which is the minimum necessary for using the elevator, and is inorganic. The display section of the hall indicator is generally monochromatic, and the display dots are coarse. If the user does not go to the elevator hall due to display area restrictions, the current position (current floor) of the car is confirmed. Because it was not possible, it was very inconvenient for users.

  Lanterns are mainly installed in elevator halls where multiple elevators are operated as a means of notifying the user that the elevator car is close to the corresponding floor (floor) and landing on that floor. It was only a function to inform the planned unit and landing. The landing of the car on the corresponding floor can be judged from a location away from the elevator hall, but it is inconvenient for the passengers because the specific car position during traveling cannot be known.

  Furthermore, the announcement has a function of guiding the elevator operation information by voice, but it is inconvenient that it is only the landing information by voice guidance and the specific car position cannot be known.

  Although the irradiation apparatus installed in the elevator hall proposed in Patent Document 1 described above can display elevator operation information and advertisements, the display direction and display range are always constant and cannot be moved. Due to effects such as enlargement, reduction and blinking of the display range, it is not possible to provide guidance to users who are away from the elevator hall.

  The present invention has been made in view of such circumstances, and the operation state of the elevator including the current position of the car can be determined at a glance by looking at the projected area of the image even from a position away from the elevator hall. Furthermore, it is possible to provide an elevator hall guide device that can further improve the service for passengers in the elevator hall by allowing users to view external information video supplied from outside during the waiting time of the car as required. With the goal.

  In order to solve the above-mentioned problems, the elevator hall guide device of the present invention is provided and detected in an elevator state on each floor of the building, with an operation state detecting means for detecting the operation state of the elevator including the current position of the elevator car. Projectors that project images of the operating status of elevators, and projectors installed in the elevator halls on each floor, depending on the current position of the car in which the projection area of the images is detected, And a rotation support mechanism that rotatably supports the surface so as to move continuously.

  In the elevator hall guide device constructed as described above, the elevator operating state including the current position of the elevator car is determined by the rotation support mechanism, and the projected area of the image is continuous with the wall surface and floor surface of the elevator hall. The image is projected by the moving projector.

  Therefore, since only the projection area of the image can be confirmed from a position away from the elevator hall, the current position of the car can be determined at a glance from a position away from the elevator hall.

  According to another aspect of the present invention, the rotation support mechanism in the elevator hall guide apparatus according to the above-described invention has a projection area when the current position of the detected car is a floor where the rotation support mechanism is installed and a nearby floor. Is supported on the floor so that the projection area is located on the wall when the current position of the detected car is on a floor far away from the floor where the rotation support mechanism is installed. .

  In the elevator hall guide apparatus configured as described above, when the current position of the car is the floor where the projector is installed and the nearby floor, the floor is displayed on the floor surface of the elevator hall near the door, for example. So you can grasp it more easily.

  Another invention is the elevator hall guide apparatus according to the above-described invention, wherein the image of the elevator operating state projected on the wall surface and floor surface of the elevator hall by the projector is different according to the detected current position of the car. Video form changing means is provided. In such a configuration, when the car approaches the floor, the user can be alerted by displaying an enlarged image of the floor.

  According to another invention, in the elevator hall guide device according to the above-described invention, when the current position of the detected car is a floor far away from the floor where the rotation support mechanism is installed, the elevator is operated by the projector. External information projection means for stopping projection of the state image and projecting the image of the information supplied from the outside to the projector on the wall surface.

  In such a configuration, when the elevator car is on a floor far from this floor, it is possible to project, for example, a news video supplied from the outside rather than the elevator operation state on the wall of the elevator hall.

  According to another invention, in the elevator hall guiding apparatus according to the above-described invention, a user detecting means for detecting whether or not an elevator user is present in the elevator hall, and the user detecting means detects the user. And a projection canceling means for canceling the projection of the image of the elevator operating state by the projector. In such a configuration, when there are no passengers in the elevator hall, nothing is projected onto the elevator hall, so that power consumption can be reduced.

  According to another aspect of the present invention, in the elevator hall guidance apparatus according to the present invention, external information projection means for projecting an image of information supplied from the outside onto the projector when the user detection means does not detect a user. It has. In such a configuration, a person who is not waiting for the elevator can enjoy the external information projected on the wall surface of the elevator hall.

  According to the present invention, the operation state of the elevator including the current position of the car from a position away from the elevator hall can be determined at a glance by looking at the projected area of the image, and the service for the passengers of the elevator hall can be further improved. It can be further improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1A is a sketch of an elevator hall in which an elevator hall guide device according to an embodiment of the present invention is installed. On the front wall 1 of the elevator hall, an entrance / exit 2 for an elevator car is formed, and a door 3 is attached to the entrance / exit 2. A hall call registration device 4 is attached to the front wall 1 on the right side of the door 3. The landing call registration device 4 is provided with lower and upper call buttons 5a and 5b and a display (elevator indicator) 6 for displaying the current car position.

  Further, a rotation support portion 8 that rotatably supports the projector 7 is attached to a position near the ceiling 11 of the front wall 1. The rotation support unit 8 supports the cylindrical projector 7 so as to be rotatable (rotation angle θ) in a parallel plane of the front wall 1 and can be tilted (inclined) in a plane orthogonal to the front wall 1. Support at the angle φ).

  Since the projector 7 projects an image of the elevator operation state including the current position (floor) of the car as will be described later, the rotation support unit 8 adjusts the rotation angle θ and the inclination angle φ. Thus, it is possible to project an image of the elevator operation state including the current position (floor) of the car at arbitrary positions on the side wall surface 10 and the floor surface 12 of the elevator hall.

  The projector 7 may employ any one of LCD, DLP, and LCOS general-purpose projectors, from a high-brightness projector such as a metal halide or halogen projector.

  In addition, an infrared camera 9 is installed on the front wall 1 on the left side of the door 3 as user detecting means for detecting, for example, by infrared rays that there is an elevator user 13 in the elevator hall. It should be noted that the user detecting means may employ light, ultrasonic waves, or the like.

  FIG. 1B is a sketch showing the inside of the elevator car 14. A door 15 is provided in the car 14, and a car call registration device 16 is attached to the right side of the door 15. The car call registration device 16 includes a forced open / close button 17 and a destination button 18 of the door 15. , And a display 19 that displays the current position (floor) of the car 14 is provided.

  FIG. 2 is a block diagram illustrating a schematic configuration of the elevator hall guiding apparatus according to the embodiment. Guidance devices 20 are provided at positions where the passengers 13 of the elevator hall on each floor of the building where the elevator is installed cannot reach the eyes.

  An elevator control unit 21 is provided on the upper side of the hoistway where the elevator car 14 moves up and down. In the elevator control unit 21, the operation instruction unit 23 sends the “car call” input from the car call registration device 16 in the car 14 to the operation control unit 22, and each hall call provided in the elevator hall on each floor. The “landing call” input from the registration device 4 is sent to the operation control unit 22.

  The operation control unit 22 moves the elevator car 14 to the floor designated by each input call. The car position detection unit 24 detects the current position h in the vertical direction of the car 14 moving up and down in the boarding / alighting path and sends it to the operation control unit 22 and also sends it to the guidance device 20 on each floor. Further, the operation control unit 22 sends the operation state of the elevator at the current time point to the floor guidance device 20 on each floor.

  An external information input unit 25 is incorporated in a guide device 20 configured by, for example, a computer provided in an elevator hall on each floor of the building. Various images are input to the external information input unit 25 from the Web site 26 via the network 27, and TV video is input from a tuner 28 such as a TV, and further, playback video is output from a playback device 29 such as a VTR or a DVD player. Is entered. The external information input unit 25 sends the designated image to the projector 7 via the data buffer 31 based on the video switching instruction of the switching control unit 30. At the same time, the audio attached to the video is sent to the speaker 32 via the data buffer 31.

  Based on the current position h of the car 14 input from the car position detection unit 24 of the elevator control unit 21 and the switching instruction from the switching control unit 30, the drive control unit 33 sends the rotation support unit 8 to the projector 7. The rotation support portion 8 is instructed to set the rotation angle θ and the inclination angle φ of the projector 7 so that the projection region 36 enters the side wall surface 10 of the elevator hall. As a result, the projector 7 supported by the rotation support unit 8 can project the image 34 inputted from the outside onto the side wall surface 10 of the elevator hall and can output the sound of the image 34 from the speaker 32.

  When the infrared camera 9 attached to the front wall 1 in the vicinity of the door 3 detects the presence of the elevator user 13 within a certain distance from the door 3, the infrared camera 9 sends the presence of the user 13 to the switching control unit 30. When the presence of the customer 13 is input, the switching control unit 30 uses the projector 7 to indicate to the drive control unit 33 the current position h of the car 14 input from the elevator control unit 21 and the operating state of the elevator. Project.

  If the presence of the customer 13 is not input, the switching control unit 30 projects the image input to the external information input unit 25 described above onto the fixed projection region 36 on the side wall surface 10 of the elevator hall by the projector 7. To do.

  Next, when the current position h of the car 14 is projected on the side wall surfaces 10, 10 a, and the floor surface 12 with the number 34 indicating the floor (B1, 1, 2, 3, 4, 5) as the elevator operating state. An example will be described with reference to FIGS. A projection switching table 35 shown in FIG. 3 is formed in the switching control unit 30 of the guide device 20 provided in the elevator hall on the second floor.

In the projection switching table 35, the rotation angle θ (θ _{0 to} θ ₅ ) of the projector 7, and a number for each car position h (h _{0 to} h ₆ ) detected by the car position detection unit 24. The current floor of the car 14 indicated by is stored.

  4 is a schematic diagram showing the setting contents of the projection switching table 35 shown in FIG. 3, and FIG. 5 shows the side walls 10 and 10a of the elevator hall and the floor surface based on the setting contents of the projection switching table 35 shown in FIG. 12 is a plan view showing an image 34 and a projection area 36 projected onto the image 12. FIG.

In the section of h ₀ to h ₁ where the current position h of the car 14 is located on the B1 floor and in the vicinity thereof, the rotation angle θ of the projector 7 is a point (θ ₀₎ whose projection area 36 is on the right side wall surface 10a. The image 34 projected onto the projection area 36 of the right side wall surface 10a is “B1”.

In the section of h ₁ to h ₂ where the current position h of the car 14 is moving or located on the first floor and the vicinity thereof, the projection area 36 is located on the right side of the floor 12 and the current position h of the car 14 is h. The rotation angle θ of the projector 7 changes from θ _{1 to} θ ₂ so that the projection region 36 moves to the left on the floor surface 12 as it changes from _{1 to} h ₂ . The image 34 projected on the projection area 36 moving from θ ₁ to θ ₂ on the floor 12 maintains “1”.

Further, the current position h of the car 14 is the second floor where the guide device 20 is installed and the section h ₂ to h ₃ where the current position h is moving or located in the vicinity thereof. Of the projector 7 so that its projection area 36 moves to the left on the floor 12 as the current position h of the car 14 changes from h _{2 to} h ₃ . The rotation angle θ changes from θ ₂ → θ ₃ . While moving on the floor 12 from θ ₂ to θ ₃ or during a period when the doors 3 and 15 are opened and the passenger 13 gets on and off the car 14 while stopping, the image 34 projected on the projection area 36 is “ 2 ”is maintained.

In the section from h ₃ to h ₄ where the current position h of the car 14 is moving or located on the third floor and its vicinity, the projection area 36 is located on the left side of the floor 12 and the current position h of the car 14 is h. ₃ → with the changes into h ₄ to move the projection region 36 floor surface 12 on the left, the rotation angle theta of projector 7, changes to theta ₃ → theta _4. The image 34 projected on the projection area 36 moving from θ ₃ to θ ₄ on the floor 12 maintains “3”.

Furthermore, in the section of h ₄ to h ₅ where the current position h of the car 14 is located on the fourth floor and in the vicinity thereof, the rotation angle θ of the projector 7 is a point on the side wall surface 10 on the left side of the projection area 36 ( θ ₅ ), and the image 34 projected onto the projection area 36 of the left side wall surface 10 is “4”.

Finally, in the section from h ₅ to h ₆ where the current position h of the car 14 is located on the fifth floor and in the vicinity thereof, the rotation angle θ of the projector 7 is a point on the side wall surface 10 on the left side of the projection area 36. (theta ₅₎ is secured to, the image 34 projected on the projection area 36 of the side wall surface 10 of the left side is "5".

  That is, when the current position of the car 14 is the B1 floor, the 4th floor, or the 5th floor, which is far away from the 2nd floor where the guide device 20 is installed, the left and right side wall surfaces 10, 10a is displayed in the same projection area 36a.

  In the projection switching table 35 of the guide device 20 provided in an elevator hall other than the second floor, for example, the third floor elevator hall, when the current position of the car 14 is the third floor, a video “3” is displayed. The relationship between the current position h of the car 14 and the rotation angle θ of the projector 7 is reset so that it is projected in front of the door 3 on the floor 12.

  FIG. 6 is a flowchart showing the projection control of each guide device 20. For example, when a minute time Δt such as 0.1 second elapses (step S1), the current position h of the car 14 is detected (S2). Then, the presence or absence of the elevator user 13 is checked with the infrared camera 9 (S3). If there is the elevator user 13, the rotation of the projector 7 corresponding to the current position h of the car 14 from the projection switching table 35. The angle θ is read (S4), and set to the rotation support unit 8 via the drive control unit 33 (S5). Further, the "floor" image 34 corresponding to the current position h of the car 14 is sent from the projection switching table 35 to the projector 7 and projected onto the side wall surface 10, 10a or the floor surface 12 of the elevator hall (S6). . Then, the process returns to S1.

When there is no elevator user 13 (S3), the rotation angle θ of the projector 7 is set to θ ₅ in the direction of the side wall surface 10 (S7), and the image input to the external information input unit 25 Is projected onto the side wall surface 10 of the elevator hall by the projector 7 (S8).

  In the elevator hall guide apparatus configured as described above, when the elevator car 14 is, for example, on the fifth floor far away from the second floor where the guide apparatus 20 is installed, for example, as shown in FIG. Is projected onto the fixed projection area 36 on the side wall surface 10 of the elevator hall by the projector 7.

  When the car 14 moves from the fifth floor to, for example, the second floor where the guidance device 20 is installed, when the current position h of the car 14 enters a position near the third floor, “3” is placed at the left end of the floor 12 of the elevator hall. "Is projected. The “3” image 34 moves to the right on the floor 12 in conjunction with the downward movement of the car 14.

  When the current position h of the car 14 enters a position near the second floor, the “3” image 34 projected on the floor 12 of the elevator hall changes to the “2” image 34. When the car 14 accurately reaches the second floor position, the image 34 of “2” stops at a position in front of the door 3 as shown in FIG. Then, the doors 3 and 15 are opened.

  When there is no elevator user 13, as shown in FIGS. 9 (a) and 9 (b), projection of the image 34 of the elevator operation state is stopped and input to the external information input unit 25. The image 37 is projected by the projector 7 onto the side wall surface 10 of the elevator hall.

  Therefore, since only the projection area 36 of the image 34 can be confirmed from a position away from the elevator hall, the current position of the car 14 can be determined at a glance from a position away from the elevator hall.

  Furthermore, when the current position h of the car 14 is the floor where the guide device 20 is installed and the nearby floor, the image 34 of the corresponding floor is projected on the floor surface 12 in front of the door 3 of the elevator hall. Easy to grasp.

  A person who is not waiting for the elevator can enjoy a video 37 of external information such as news and music projected on the side wall surface 10 of the elevator hall together with sound when there is no elevator user 13.

  In addition, this invention is not limited to embodiment mentioned above.

  When the elevator passenger 13 is not present in the elevator hall, the projection of the image 34 of the elevator operation state by the projector 7 may be stopped. In this case, nothing is projected onto the elevator hall, so that power consumption can be saved.

  In this case, as a matter of course, even when the car call and the hall call are not registered and the car 14 is stopped on any floor, the projection of the image 34 of the elevator operation state by the projector 7 is stopped. Also good.

  Further, for example, as shown in FIG. 10, an arrow indicating a moving direction in a number indicating the current position of the car 14 as an image 34 of an elevator operation state projected onto the side wall surfaces 10, 10 a and the floor surface 12 by the projector 7. Can be added.

  Further, as shown in FIGS. 11A to 11C, the current position h of the car 14 is set on the floor where the guide device 20 is installed and the hall call is registered by the hall call registration device 4 on the corresponding floor. As approaching, the projected image 34 can be enlarged. Specifically, it can be realized by adopting a zoom lens that can be remotely operated as the lens of the projector 7.

  Further, as shown in FIG. 12 (a), the current position h of the car 14 is projected as the guide device 20 is installed and approaches the floor where the hall call is registered in the hall call registration device 4 of the corresponding floor. It is also possible to project the image 34 to be blinked, or to display it with an emphasized food color such as red, as shown in FIG.

  Furthermore, as shown in FIG. 13, the projector 7 and a rotation support portion 8 that rotatably supports the projector 7 can be attached to the position adjacent to the front wall 1 of the ceiling 11.
