Abstract

A display system for an elevator includes: a speed detecting device that detects speed of an elevator car; a position detecting device that detects position of the car; an operation control system that outputs speed information, stop floor information, and car position information based on a speed detection signal and a position detection signal; and a display device that displays floor names using a display control device based on the speed information, the stop floor information, and the car position information. The floor names are displayed on a display unit in a continuous manner on a circumference of a predetermined shape, so that display positions of the continuously displayed floor names are moved on the circumference of the predetermined shape in proportion to moving speed of the car.

Claims (21)

1. A display system for an elevator comprising:

a speed detecting device that detects speed of an elevator car and outputs a speed detection signal;

a position detecting device that detects position of the elevator car and outputs a position detection signal;

an operation control system that controls operation of the elevator car and outputs speed information, stop floor information, and car position information based on the speed detection signal and the position detection signal; and

a display device installed in one of the elevator car and an elevator hall, including a display control device and a display unit

that displays a plurality of floor names using the display control device based on the speed information, the stop floor information, and the car position information so that the plurality of floor names are displayed on the display unit in a continuous manner on a circumference of a predetermined shape,

that displays a floor name corresponding to a current position of the elevator car distinguishably from a floor name of each floor, other than a current floor, and

that displays the plurality of continuously displayed floor names so that display positions of the plurality of continuously displayed floor names are moved on the circumference of the predetermined shape in proportion to moving speed of the elevator car.

2. The display system for an elevator according to claim 1 , wherein the display device displays the floor name corresponding to the current position of the elevator car in a bigger size than others of the plurality of continuously displayed floor names, using the display control device, and displays each floor name, other than the current floor, while gradually reducing size of each floor name from the size of the floor name corresponding to the current position, in accordance with an increase in distance from the current position of the elevator car.

3. The display system for an elevator according to claim 1 , wherein the display device displays each stop floor in a direction in which the elevator car is traveling, distinguishably from the floor name corresponding to the current position of the elevator car, and each floor name, other than the current floor, using the display control device.

4. A display method for an elevator in which a current floor of an elevator car is indicated on a display unit provided in one of an elevator car and an elevator hall, comprising:

displaying, on the display unit, a loop-shaped icon array obtained by arranging a plurality of floor name icons provided for respective floors in a loop shape in the order of floor number; and

rotating the loop-shaped icon array in accordance with movement of the elevator car so that a floor name icon of a current floor is arranged at a predetermined position on the display unit.

5. The display method for an elevator according to claim 4 , wherein

the floor name icon of the current floor is displayed in a bigger size on the display unit than other floor name icons, and

the other floor name icons are displayed on the display unit in sizes that are gradually reduced in accordance with an increase in distance from the floor name icon of the current floor.

6. The display method for an elevator according to claim 4 , wherein

the floor name icon of the current floor is displayed in a specific color on the display unit, and

when the current floor is changed due to travel of the elevator car, the icon displayed in the specific color is switched to a floor name icon of a new current floor.

7. The display method for an elevator according to claim 6 , wherein a floor name icon of each stop floor is displayed in a second specific color on the display unit.

8. The display method for an elevator according to claim 7 , wherein a content image corresponding to each of the stop floors is displayed beside the loop-shaped icon array on the display unit.
