Abstract

A portable input apparatus permits an elevator destination call to be generated remotely from an associated elevator installation with respect to time and location. The input apparatus can be formed as, for example, a wristwatch having a user interface including a first display for visually indicating data, a first keyboard for the manual input of data or travel commands and an audio unit for the acoustic input of data or travel commands and for the generation of audio information to the elevator user. A destination floor identification, such as the English word “twenty-seven”, can be an acoustic command destination call entered into the input apparatus and indicated on the first display as “27” whereby in the proximity of the elevator installation, the destination call is automatically communicated to an elevator control of the elevator installation. The elevator control then communicates to the portable input apparatus the identity of the elevator car that has been assigned to serve the call.

Claims

1. An apparatus for inputting an elevator command to an elevator installation having an elevator control comprising:

a portable input means for receiving, storing and transmitting data in a plurality of acoustic elevator commands;

an audio unit included in said input means for reception and conversion of each of said acoustic elevator commands to related elevator command data;

a transmitter/receiver unit in said input means for non-acoustic communication of said elevator command data; and

a control unit included in said input means and connected to said audio unit and said transmitter/receiver unit for controlling inputting of said acoustic elevator commands when said input means is located remote from an associated elevator installation and storing the related elevator command data for later non-acoustic communication to an elevator control of the associated elevator installation when said input means is proximate the elevator control, said control unit being responsive to an interrogation communication received by said transmitter/receiver unit for generating said non-acoustic communication to the elevator control.

2. The apparatus according to claim 1 wherein said portable input means includes a display unit for visually indicating said elevator command data.

3. The apparatus according to claim 2 wherein said portable input means includes a keyboard connected to said control unit for input of additional data representing at least one of individual user data, elevator operating data, elevator system data and elevator travel destination data, said display unit visually indicating said additional data.

4. The apparatus according to claim 2 wherein said portable input means includes a memory connected to said control unit for storage of said elevator command data and said additional data.

5. The apparatus according to claim 4 wherein said memory includes a first storage block for storing said individual user data, a second storage block for storing said elevator operating and system data, a third storage block for storing a synonym table, a fourth storage block for storing restriction data for elevator use, a fifth storage block for storing routines of a user and a sixth storage block for storing a desired travel destination represented by said elevator command data.

6. The apparatus according to claim 1 wherein said transmitter/receiver unit in said input means is a first transmitter/receiver unit that communicates said elevator command data to a second transmitter/receiver unit at a call terminal of the associated elevator installation.

7. The apparatus according to claim 6 wherein said first transmitter/receiver unit communicates with the second transmitter/receiver unit by infrared signals.

8. The apparatus according to claim 6 wherein said first transmitter/receiver unit communicates said elevator command data in response to receiving said interrogation communication from the second transmitter/receiver unit.

9. The apparatus according to claim 1 wherein said audio unit includes a microphone for reception of said acoustic elevator commands, a loudspeaker for generating audio information and an audio transducer connected to said microphone and to said loudspeaker for speech recognition in response to said acoustic elevator commands and speech synthesis to generate said audio information.

10. A system for inputting an elevator command to an elevator installation comprising:

an elevator control for controlling an elevator installation;

a portable input means for receiving, storing and transmitting data in a plurality of acoustic elevator commands for said elevator control;

an audio unit included in said input means for reception and conversion of each of said acoustic elevator commands to related elevator command data;

a first transmitter/receiver unit in said input means for non-acoustic communication of said elevator command data to said elevator control; and

a first control unit included in said input means and connected to said audio unit and said first transmitter/receiver unit for controlling inputting of said acoustic elevator commands when said input means is located remote from said elevator control and storing the related elevator command data for later non-acoustic communication to said elevator control when said input means is within communication range of said elevator control said control unit being responsive to an interrogation communication received by said transmitter/receiver unit for generating said non-acoustic communication to the elevator control.

11. The system according to claim 10 wherein said elevator control includes a second transmitter/receiver unit and said first transmitter/receiver unit communicates said elevator command data to said second transmitter/receiver unit in response to receiving said interrogation communication from said second transmitter/receiver unit.

12. The system according to claim 11 wherein said first transmitter/receiver unit and said second transmitter/receiver unit communicate by infrared signals.

13. A method for remotely inputting an elevator command to an elevator installation having an elevator control comprising the steps of:

a. receiving an acoustic elevator command at a location remote from an associated elevator control of an elevator installation;

b. storing the acoustic elevator command in a portable input means for later non-acoustic communication to the elevator control; and

c. automatically communicating the stored acoustic elevator command to the elevator control by wireless non-acoustic communication when the portable input means is within communication range of the elevator control and in response to receiving an interrogation communication.

14. The method according to claim 13 including indicating to a user of the elevator installation by at least one of acoustically and optically an elevator assigned in response to the acoustic elevator command.

15. The method according to claim 13 wherein the acoustic elevator command is a destination floor number.
