BEST MODE FOR CARRYING OUT THE INVENTION

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

Embodiment 1.

FIG. 1 is a side view showing an elevator information display system according to Embodiment 1 of the present invention, FIG. 2 is a front view of the information display system of FIG. 1 as seen from the inside of a car, and FIG. 3 is the information display system of FIG. FIG.

In the figure, a fog generating device 2 as a screen generating means for generating a fog screen (fog screen) 3 in the car 1 is provided on the upper part (ceiling part) of the car 1. The screen 3 is formed by blowing air into two thin layers and blowing a dense and uniform mist layer between the air layers. That is, the screen 3 is formed by sandwiching a mist layer between two air layers. The screen 3 is generated at a position opposite to the force entrance.

[0010] A water tank 4 installed on the force cylinder 1 is connected to the fog generating device 2. The mist generating device 2 generates mist with water supplied from the water tank 4.

A projector 7 is installed on the upper portion of the car 1 as image display means for projecting the image 6 on the screen 3 via the mirror 5. The mirror 5 is disposed above the car door 8. The light from the projector 7 is projected from behind the screen 3. That is, the projector 7 and the mirror 5 are arranged on the car entrance side with respect to the screen 3.

[0012] The floor of the car 1 is a circuit that sucks and collects the air layer and mist constituting the screen 3. A collecting device 9 is provided as a collecting means. The collected mist is turned into water in the collector 9 and returned to the water tank 4 through the pipe 10. That is, the water in the water tank 4 is circulated through the fog generator 2, the collector 9 and the water tank 4 and repeatedly used.

The fog generating device 2 and the projector 7 are controlled by the display control device 11. The display control device 11 is connected to an information distribution device 12 that distributes video and information, and an elevator control device 13 that controls the operation of the elevator. The elevator control device 13 operates the car 1 according to the assignment from the group management device (not shown). The display control device 11 performs ONZOFF control of the screen 3 and the image 6 according to the car operation information from the elevator control device 13. In this example, screen 3 and video 6 are generated while car 1 is traveling, and screen 3 and video 6 are removed while car 1 is stopped.

FIG. 4 is a flowchart showing the operation of the display control device 11 of FIG. The display control device 11 monitors whether or not the call registration is accepted based on the information from the elevator control device 13 (step Sl). When the call registration is accepted, it is monitored whether or not the car 1 has reached the registration floor (step S2).

[0015] After the car 1 arrives at the registration floor, it is monitored whether the car 1 has started running (step S3). When the car 1 starts running, the screen 3 is generated by the fog generator 2 (step S4), and then the display of the image 6 is started by the projector 7 (step S5).

[0016] Thereafter, the display control device 11 monitors whether the force 1 has arrived at the destination floor (step S6). Display of image 6 continues until force 1 arrives at the destination floor. When force 1 arrives at the destination floor, display of video 6 is stopped (step S7) and screen 3 is removed (step S8).

[0017] When the screen 3 is removed on the destination floor, the display control device 11 checks whether another destination floor is registered (step S9). If registered, the process returns to step S3. If not registered, the process returns to step S1 and waits.

[0018] In such an elevator information display system, since the image 6 is projected on the screen 3 having a layered fog force, the degree of freedom in display location is higher than when a display is installed or a door is used as a screen. Can be increased.

In addition, since screen 3 is generated in car 1, it is possible to generate a screen for each landing. The cost can be reduced compared to the case.

Furthermore, since the collector 9 is provided on the car floor, water can be circulated and the air in the car 1 can be replaced.

Furthermore, since the screen 3 is formed in front of the car doorway, the elevator user in the car 1 is prevented from standing away from the car door 8, and the elevator user is prevented from being drawn into the car door 8 when the door is opened. .

[0019] Note that examples of the image 6 displayed on the screen 3 include elevator operation information, building information, general information such as advertisements, weather forecasts, and landscape images. It is also possible to broadcast audio and music linked to video 6 from the speaker in the car 1. Further, the display controller 11 may be connected to an in-car lighting control device (not shown), and the illumination in the car 1 may be slightly dimmed while the image 6 is being displayed.

[0020] Embodiment 2.

Next, FIG. 5 is a side view showing an elevator information display system according to Embodiment 2 of the present invention. In the figure, the inclination angle of the mirror 5 can be adjusted by an actuator (not shown) or the like. The inclination angle of the mirror 5 is controlled by a mirror control device 14 as image adjusting means for driving the actuator. By changing the tilt angle of the mirror 5, the size and position of the image 6 displayed on the screen 3 are changed.

The elevator control device 13 receives car load information from a car load detection device 15 as load detection means. The mirror control device 14 also receives car load information from the elevator control device 13. Then, the mirror controller 14 adjusts the inclination angle of the mirror 15 according to the car load information.

[0022] Specifically, when the car load is higher than the threshold value, the mirror control device 14 determines that the image 6 with a large number of elevator users in the car 1 is difficult to see, and only places the image 6 at a high position. indicate. As a result, the vertical dimension of the image 6 is reduced. Conversely, when the car load is equal to or less than the threshold value, the mirror control device 14 determines that the image 6 with a small number of elevator users in the car 1 is easy to see, and displays the image 6 to a lower position. This increases the vertical dimension of image 6. Other configurations are the same as those in the first embodiment.

[0023] In such an elevator information display system, the position of image 6 is determined according to the car load information. Since the position and size are changed, the image 6 can be displayed at a position and size suitable for the number of elevator users in the car 1.

[0024] In the above example, the force by which the tilt angle of the mirror 5 is changed. The size of the image itself projected from the projector 7 may be changed.

In addition, image 6 may be projected directly from projector 7 onto screen 3 without using mirror 5.

In this case, the display position of the image may be changed by changing the angle of the projector 7. Furthermore, in the above example, only one of the forces that change the position and size of the image 6 may be changed.

Furthermore, a plurality of threshold values may be set, and the position and size of the image may be changed in three steps or more.

[0025] Embodiment 3.

Next, FIG. 6 is a front view of an elevator information display system according to Embodiment 3 of the present invention as seen from the landing. In the first and second embodiments, the screen 3 is generated only when the car 1 is running and the image 6 is displayed. In the third embodiment, the screen 3 is displayed even when the car 1 is stopped and opened. And display image 6 toward the landing. As information displayed at this time, for example, a message for elevator users at the hall, such as “I will go up”. Other configurations are the same as those in the first embodiment.

FIG. 7 is a flowchart showing the operation of the information display system of FIG. Display control device

11 monitors whether the call registration is accepted by the information from the elevator controller 13 (step Sl). When call registration is accepted, it is monitored whether or not the car 1 has arrived at the registration floor (step S2).

[0027] When force 1 arrives at the registration floor, screen 3 is generated by fog generator 2 (step

Subsequently, the image 6 for the hall is displayed on the screen 3 by the projector 7 (step S12). Thereafter, the display control device 11 monitors whether or not the car 1 has started running (step S13). When force 1 starts running, video 6 is displayed on screen 3

Switch to image 6 for 1 (step S14).

[0028] Thereafter, the display control device 11 monitors whether the force 1 has arrived at the destination floor (step S15). When Rikigo 1 arrives at the destination floor, the video 6 displayed on the screen 3 is displayed on the platform. Switch to image 6 for (step S16). Next, the display control device 11 checks whether or not another destination floor is registered (step S17), and if registered, returns to step S3.

[0029] If the destination floor is not registered, display of video 6 is stopped (step S18), screen 3 is removed (step S19), and the process returns to step S1 and waits.

[0030] In such an elevator information display system, when the car 1 is stopped at the stop floor and opened, the image 6 for the landing is displayed on the screen 3 formed in front of the entrance. Information can be effectively communicated to waiting elevator users.

Further, since the screen 3 is composed of an air layer and a fog layer, the elevator user can move between the car 1 and the landing area across the screen 3 even when the screen 3 is generated.

Note that the display control device 11 may be omitted, and the fog generation device 2 and the projector 7 may be directly controlled by the elevator control device 13.

The screen generating means and the video display means may be installed at the landing. In addition, a plurality of screen generation means and a plurality of video display means should be provided in one cage.

Furthermore, in the above example, the force generated when the screen is generated vertically The direction of the screen is not particularly limited, and may be generated horizontally or diagonally.
