Abstract

Elevator reassignment information is communicated to passengers in a group elevator system (10). The group elevator system (10) includes a group of elevators (14a, 14b, 14c) that is operable to transport each of the passengers to one of a plurality of floors (L, F2, F3, F4, F5). A destination entry input device (30, 35) at each floor permits each passenger to enter destination input information. A dispatch controller (20) assigns an elevator to each passenger based on the destination input information. When service of a dispatched elevator is terminated, a communication device (46, 50) communicates elevator reassignment instructions to passengers assigned to or located in the dispatched elevator.

Claims

1. A system comprising:

a group of elevators operable to transport each of a plurality of passengers to one of a plurality of floors;

a destination entry input device at each floor for permitting each passenger to enter destination input information;

a dispatch controller for assigning an elevator to each passenger based on the destination input information;

a sensing device for determining whether passengers remain in the dispatched elevator after service of the dispatched elevator is terminated; and

a communication device for communicating elevator reassignment instructions to passengers assigned to or located in a dispatched elevator when service of the dispatched elevator is terminated.

2. The system of claim 1, wherein the destination entry input device comprises a keypad.

3. The system of claim 1, wherein the destination entry input device comprises a touch screen display.

4. The system of claim 1, wherein the communication device comprises an electroacoustic transducer.

5. The system of claim 1, wherein the communication device comprises an electronic display.

6. The system of claim 1, wherein the reassignment instructions are communicated to floors on which a passenger provided destination input information on the destination entry input device.

7. The system of claim 1, wherein the sensing device comprises a motion detector.

8. A method for communicating with passengers in a group elevator system, the method comprising:

receiving destination input information from each passenger on a destination entry input device;

assigning an elevator to each passenger based on the destination input information;

determining whether passengers remain in the dispatched elevator after service of the dispatched elevator is terminated; and

providing elevator reassignment instructions to passengers assigned to a dispatched elevator or passengers not assigned to, but located in, the dispatched elevator when service of the dispatched elevator is terminated.

9. The method of claim 8, wherein providing elevator reassignment instructions to passengers comprises audibly communicating the elevator reassignment instructions to the passengers.

10. The method of claim 8, wherein providing elevator reassignment instructions to passengers comprises visually communicating the elevator reassignment instructions to the passengers.

11. The method of claim 8, wherein providing elevator reassignment instructions to passengers comprises:

instructing each passenger to reenter their destination input information on a nearest destination entry input device; and

reassigning each passenger to a new elevator based on their destination input information.

12. The method of claim 8, and further comprising:

providing passengers who remain in the dispatched elevator with instructions regarding exiting the dispatched elevator.

13. A method for controlling elevator assignment in a destination entry group elevator system, the method comprising:

receiving destination input information from each passenger on a destination entry input device;

assigning an elevator to each passenger based on the destination input information;

determining when service of a dispatched elevator is terminated;

determining whether passengers remain in the dispatched elevator after service of the dispatched elevator is terminated;

instructing each passenger assigned to the dispatched elevator to reenter destination input information on a destination entry input device; and

reassigning each passenger to a new elevator based on the reentered destination input information.

14. The method of claim 13, wherein providing elevator reassignment instructions to passengers comprises audibly communicating the elevator reassignment instructions to the passengers.

15. The method of claim 13, wherein providing elevator reassignment instructions to passengers comprises visually communicating the elevator reassignment instructions to the passengers.

16. The method of claim 13, and further comprising:

providing passengers who remain in the dispatched elevator with instructions regarding exiting the dispatched elevator.

17. A system comprising:

a group of elevators operable to transport each of a plurality of passengers to one of a plurality of floors;

a destination entry input device at each floor for permitting each passenger to enter destination input information;

a dispatch controller for assigning an elevator to each passenger based on the destination input information;

a communication device for communicating elevator reassignment instructions to passengers assigned to or located in a dispatched elevator when service of the dispatched elevator is terminated; and

a sensing device for determining whether passengers remain in the dispatched elevator after service of the dispatched elevator is terminated.

18. A method for communicating with passengers in a group elevator system, the method comprising:

receiving destination input information from each passenger on a destination entry input device;

assigning an elevator to each passenger based on the destination input information; and

providing elevator reassignment instructions to passengers assigned to a dispatched elevator or passengers not assigned to, but located in, the dispatched elevator when service of the dispatched elevator is terminated, wherein the elevator reassignment instructions are provided by instructing each passenger to reenter their destination input information on a nearest destination entry input device and reassigning each passenger to a new elevator based on their destination input information.
