Abstract

An elevator controller includes a microphone that receives voice of a passenger in a car, a memory that, for a destination floor specifying operation for the passenger to specify a destination floor by voice, stores a first keyword defined beforehand to signify an operation start and second keywords defined beforehand to signify a destination floor, a voice recognition unit that compares a voice inputted from the microphone with the stored first and second keywords, and a controller that, when the door of the car is fully open or fully close, the voice recognition unit recognizes the first keyword and thereafter recognizes a second keyword, registers a destination floor corresponding to the second keyword. The controller outputs a command to suspend an operation to open or close the door of the car until the destination floor specifying operation is ended after the voice recognition unit recognizes the first keyword.

Claims

1. An elevator control device comprising:

a voice input unit that is provided in a car to receive a voice of a passenger in the car;

a memory that, in relation to a destination floor specifying operation for the passenger to specify a destination floor by voice, stores a first keyword defined beforehand to signify a start of the operation and second keywords each defined beforehand to signify a destination floor;

a voice recognition unit that compares the voice inputted through the voice input unit with the first and second keywords stored in the memory; and

a controller that, when in a state in which a door of the car is fully opened or fully closed, the voice recognition unit recognizes the first keyword and thereafter recognizes one of the second keywords, registers a destination floor corresponding to the one of the second keywords,

wherein when the voice recognition unit recognizes the first keyword, the controller outputs a command to suspend an operation of opening and closing the car door, and thereafter outputs a command to cancel the suspension, and

wherein if the voice recognition unit recognizes one of the second keywords within a first predetermined time after the recognition of the first keyword and does not recognize anew the first keyword within a second predetermined time after the recognition of the one of the second keywords, the controller outputs a command to cancel the suspension of the operation of opening and closing the car door when the second predetermined time passes after the recognition of the one of the second keywords.

2. The elevator control device according to claim 1, wherein if the voice recognition unit does not recognize any of the second keywords within the first predetermined time after the recognition of the first keyword, the controller outputs a command to cancel the suspension of the operation of opening and closing the car door when the first predetermined time passes after the recognition of the first keyword.

3. The elevator control device according to claim 1, further comprising:

a passenger number detection means that detects, when the car stops at a hall, the number of passengers to get in the car,

wherein the controller determines the first predetermined time and the second predetermined time according to the detected number of passengers.

4. The elevator control device according to claim 2, further comprising:

a passenger number detection means that detects, when the car stops at a hall, the number of passengers to get in the car,

wherein the controller determines the first predetermined time and the second predetermined time according to the detected number of passengers.

5. The elevator control device according to claim 3, wherein the controller determines the first predetermined time and the second predetermined time according to the number of destination floors having already been registered.

6. The elevator control device according to claim 4, wherein the controller determines the first predetermined time and the second predetermined time according to the number of destination floors having already been registered.

7. The elevator control device according to claim 1,

wherein the memory stores not only the first and second keywords but also a third keyword defined beforehand to signify the end of the destination floor specifying operation,

the voice recognition unit compares a voice inputted from the voice input unit with not only the first and second keywords stored in the memory but also the third keywords stored therein, and

the controller outputs, when the voice recognition unit recognizes the first keyword and thereafter recognizes the third keyword, a command to cancel the suspension of the operation of opening and closing the car door.

8. The elevator control device according to claim 2,

wherein the memory stores not only the first and second keywords but also a third keyword defined beforehand to signify the end of the destination floor specifying operation,

the voice recognition unit compares a voice inputted from the voice input unit with not only the first and second keywords stored in the memory but also the third keywords stored therein, and

the controller outputs, when the voice recognition unit recognizes the first keyword and thereafter recognizes the third keyword, a command to cancel the suspension of the operation of opening and closing the car door.

9. The elevator control device according to claim 2,

wherein the memory stores not only the first and second keywords but also a third keyword defined beforehand to signify the end of the destination floor specifying operation,

the voice recognition unit compares a voice inputted from the voice input unit with not only the first and second keywords stored in the memory but also the third keywords stored therein, and

the controller outputs, when the voice recognition unit recognizes the first keyword and thereafter recognizes the third keyword, a command to cancel the suspension of the operation of opening and closing the car door.

10. The elevator control device according to claim 6,

wherein the memory stores not only the first and second keywords but also a third keyword defined beforehand to signify the end of the destination floor specifying operation,

the voice recognition unit compares a voice inputted from the voice input unit with not only the first and second keywords stored in the memory but also the third keywords stored therein, and

the controller outputs, when the voice recognition unit recognizes the first keyword and thereafter recognizes the third keyword, a command to cancel the suspension of the operation of opening and closing the car door.

11. The elevator control device according to claim 1, further comprising:

a first indicator that, after the voice recognition unit recognizes the first keyword, indicates inside the car that the destination floor specifying operation starts.

12. The elevator control device according to claim 2, further comprising:

a first indicator that, after the voice recognition unit recognizes the first keyword, indicates inside the car that the destination floor specifying operation starts.

13. The elevator control device according to claim 3, further comprising:

a first indicator that, after the voice recognition unit recognizes the first keyword, indicates inside the car that the destination floor specifying operation starts.

14. The elevator control device according to claim 7, further comprising:

a first indicator that, after the voice recognition unit recognizes the first keyword, indicates inside the car that the destination floor specifying operation starts.

15. The elevator control device according to claim 9, further comprising:

a first indicator that, after the voice recognition unit recognizes the first keyword, indicates inside the car that the destination floor specifying operation starts.

16. The elevator control device according to claim 1, further comprising:

a second indicator that indicates inside the car whether or not a destination floor specified by the controller is registered.

17. The elevator control device according to claim 2, further comprising:

a second indicator that indicates inside the car whether or not a destination floor specified by the controller is registered.

18. The elevator control device according to claim 3, further comprising:

a second indicator that indicates inside the car whether or not a destination floor specified by the controller is registered.

19. The elevator control device according to claim 7, further comprising:

a second indicator that indicates inside the car whether or not a destination floor specified by the controller is registered.

20. The elevator control device according to claim 14, further comprising:

a second indicator that indicates inside the car whether or not a destination floor specified by the controller is registered.
