Abstract

A method of allocating calls of a lift installation with at least one lift and at least one car per lift to move passengers in a journey from at least one input floor to at least one destination floor, a system for executing the method and a computer readable memory with instructions for executing the method. The method includes receiving input calls from passengers travelling from an input floor to a destination floor, each call identifying at least one floor as an input floor or a destination floor. A start zone with identified input floors and a destination zone with identified destination floors are determined from the input calls and destination calls. Each identified floor within a corresponding zone is considered using at least one selection criterion and a stopping floor is selected which satisfies the criterion. The car is caused to stop at fewer than all the identified input floors and identified destination floors during the journey.

Claims

1. A lift installation operation method, comprising:

determining, for a lift journey and using a computer, a start zone in a building, the start zone comprising input building floors identified in destination calls inputted by two or more passengers;

determining, for the lift journey and using the computer, a destination zone in the building, the destination zone comprising destination building floors identified in the destination calls;

selecting, using the computer, a stopping floor from the start zone of floors or from the destination zone of floors, the selecting of the stopping floor being based on a selection criterion; and

transporting the two or more passengers in a car of a lift installation between the start zone and the destination zone during the lift journey, the transporting comprising omitting a stop for at least one of the input building floors or at least one of the destination building floors.

2. The lift installation operation method of claim 1, further comprising communicating to one of the passengers to exit the car at a floor other than a destination building floor identified in a destination call inputted by the passenger.

3. The lift installation operation method of claim 1, further comprising communicating to one of the passengers to enter the car at a floor other than an input building floor identified in a destination call inputted by the passenger.

4. The lift installation operation method of claim 3, the communicating to the one of the passengers being performed using a destination call input terminal.

5. The lift installation operation method of claim 3, the communicating to the one of the passengers being performed before the passenger enters the car.

6. The lift installation operation method of claim 1, the selection criterion comprising passenger identification.

7. The lift installation operation method of claim 1, the selection criterion comprising a predefined input floor.

8. The lift installation operation method of claim 1, the selection criterion comprising a number of inputted destination calls.

9. The lift installation operation method of claim 1, the selection criterion comprising a lowest floor difference.

10. The lift installation operation method of claim 1, the selection criterion comprising a floor number.

11. The lift installation operation method of claim 1, the selection criterion comprising a substitute cost.

12. A lift installation, comprising:

a car; and

a lift control, the lift control comprising a processor and a computer readable data memory, the computer readable data memory having encoded thereon instructions that, when executed by the processor, cause the lift control to perform a method, the method comprising,

determining, for a lift journey and using a computer, a start zone in a building, the start zone comprising input building floors identified in destination calls inputted by two or more passengers,

determining, for the lift journey and using the computer, a destination zone in the building, the destination zone comprising destination building floors identified in the destination calls,

selecting, using the computer, a stopping floor from the start zone of floors or from the destination zone of floors, the selecting of the stopping floor being based on a selection criterion, and

transporting the two or more passengers in the car between the start zone and the destination zone during the lift journey, the transporting comprising omitting a stop at at least one of the input building floors or at least one of the destination building floors.

13. A computer readable memory programmed with instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:

determining, for a lift journey and using a computer, a start zone in a building, the start zone comprising input building floors identified in destination calls inputted by two or more passengers;

determining, for the lift journey and using the computer, a destination zone in the building, the destination zone comprising destination building floors identified in the destination calls;

selecting, using the computer, a stopping floor from the start zone of floors or from the destination zone of floors, the selecting of the stopping floor being based on a selection criterion; and

transporting the two or more passengers in a car of a lift installation between the start zone and the destination zone during the lift journey, the transporting comprising omitting a stop at at least one of the input building floors or at least one of the destination building floors.

14. A lift installation operating method, comprising:

receiving, using a destination call input terminal, a destination call for a passenger, the destination call being associated with an indicated departure floor in a building and with an indicated destination floor in the building;

determining, using a computer, a start zone of floors in the building and a destination zone of floors in the building, the determining being based on the destination call for the passenger and another destination call for another passenger; and

based on the start zone of floors and the destination zone of floors, instructing the passenger to board a lift car at a floor other than the indicated departure floor or to exit the lift car at a floor other than the indicated destination floor, the lift car being a single-cabin lift car.

15. The lift installation operating method of claim 14, the instructing the passenger to board the lift car at the floor other than the indicated departure floor comprising:

displaying travel data for traveling from the indicated departure floor to the floor other than the indicated departure floor.

16. The lift installation operating method of claim 14, the instructing the passenger to exit the lift car at the floor other than the indicated destination floor comprising:

displaying travel data for traveling from the floor other than the indicated destination floor to the indicated destination floor.

17. The lift installation operating method of claim 14, further comprising communicating state data of the lift installation to the passenger.

18. The lift installation operating method of claim 17, the state data of the lift installation comprising an indication of a floor at which the lift car will not stop during a lift trip.

19. The lift installation operating method of claim 17, the state data of the lift installation comprising an indication that a lift trip from the indicated departure floor to the indicated destination floor will be available later.

20. The lift installation operating method of claim 14, further comprising determining a substitute cost for the indicated departure floor or the indicated destination floor.
