Abstract

An elevator-calling device and elevator system. The elevator-calling device includes a processor to receive an input instruction and send a signal to a main controller of an elevator system; a display device connected to the processor; a rotatable button, wherein the rotatable button is connected to the processor, and the rotatable button is pressable and rotatable in a first direction and a second direction opposite to the first direction, and wherein the rotatable button has an initial zero scale; and an assistant sound generating unit connected to the processor; wherein the processor is configured to have an assistant elevator-calling mode, in which a preset target floor is increased when the rotatable button rotates in the first direction, the preset target floor is decreased when the rotatable button rotates in the second direction, and the preset target floor is confirmed when the rotatable button is pressed at a non-zero scale.

First claim

What is claimed is:

1. An elevator-calling device, comprising:
a processor, which is configured to receive an input instruction and send a signal to a main controller of an elevator system;
a display device connected to the processor;
a rotatable button, wherein the rotatable button is connected to the processor, and the rotatable button is pressable and rotatable in a first direction and a second direction opposite to the first direction, and wherein the rotatable button has an initial zero scale; and
an assistant sound generating unit connected to the processor;
wherein the display device is touchable for inputting a target floor in a normal elevator-calling mode;
wherein the processor is configured to have an assistant elevator-calling mode, in which a preset target floor is increased when the rotatable button rotates in the first direction, the preset target floor is decreased when the rotatable button rotates in the second direction, and the preset target floor is confirmed when the rotatable button is pressed at a non-zero scale.

2. The elevator-calling device according to claim 1 , wherein the processor is configured to enter the assistant elevator-calling mode when the rotatable button at the zero scale is pressed and/or rotated.

3. The elevator-calling device according to claim 1 , wherein the rotatable button is configured with a scale tactile sensation when rotating.

4. The elevator-calling device according to claim 3 , wherein the processor is configured to, when entering the assistant elevator-calling mode, take the floor on which the elevator-calling device is located or the 1 st floor as an initial preset target floor, and wherein each time the rotatable button rotates by one scale in the first direction, the preset target floor is increased by one, and each time the rotatable button rotates by one scale in the second direction, the preset target floor is decreased by one.

5. The elevator-calling device according to claim 1 , wherein the assistant sound generating unit broadcasts a prompt of operation mode when entering the elevator-calling mode.

6. An elevator-calling device, comprising:
a processor, which is configured to receive an input instruction and send a signal to a main controller of an elevator system;
a display device connected to the processor;
a rotatable button, wherein the rotatable button is connected to the processor, and the rotatable button is pressable and rotatable in a first direction and a second direction opposite to the first direction, and wherein the rotatable button has an initial zero scale; and
an assistant sound generating unit connected to the processor;
wherein the processor is configured to have an assistant elevator-calling mode, in which a preset target floor is increased when the rotatable button rotates in the first direction, the preset target floor is decreased when the rotatable button rotates in the second direction, and the preset target floor is confirmed when the rotatable button is pressed at a non-zero scale;
wherein the assistant sound generating unit broadcasts the preset target floor and prompts the user to confirm, when the rotatable button stays at a non-zero scale for more than a preset time t.

7. An elevator-calling device, comprising:
a processor, which is configured to receive an input instruction and send a signal to a main controller of an elevator system;
a display device connected to the processor;
a rotatable button, wherein the rotatable button is connected to the processor, and the rotatable button is pressable and rotatable in a first direction and a second direction opposite to the first direction, and wherein the rotatable button has an initial zero scale; and
an assistant sound generating unit connected to the processor;
wherein the processor is configured to have an assistant elevator-calling mode, in which a preset target floor is increased when the rotatable button rotates in the first direction, the preset target floor is decreased when the rotatable button rotates in the second direction, and the preset target floor is confirmed when the rotatable button is pressed at a non-zero scale;
wherein the rotatable button is provided with a reset mechanism configured to automatically reset the rotatable button to a position of the zero scale after the operation of the rotatable button is completed.

8. The elevator-calling device according to claim 1 , wherein a surface of the rotatable button has a Braille and/or a symbol of the disabled.

9. The elevator-calling device according to claim 1 , wherein the display device displays the preset target floor in the assistant elevator-calling mode.

10. The elevator-calling device according to claim 1 , wherein the rotatable button is a rotary encoder.

11. An elevator system, comprising:
an elevator;
a main controller configured to control the elevator; and
the elevator-calling device according to claim 1 disposed at one or more floors.
