Abstract

The invention relates to elevator systems, in which a number of elevators operate in the same hoistway. The elevator system comprises at least one shuttle elevator and at least two local elevators, the elevator-cars of which are arranged to travel in the same elevator hoistway such that they can serve at least one shared transfer floor of a transfer level. The control system of the elevator system receives destination calls given from a destination call appliance, forms a plurality of route alternatives and allocates a destination call to one or more elevators by selecting the best route alternative. When allocating a destination call, the control system takes into account that the elevator cars of the local elevators that travel in the same elevator hoistway cannot simultaneously be at a shared transfer floor in cases in which the route alternative comprises a part-trip with a local elevator and a change of elevator at a shared transfer floor.

Claims14

Dependent claims

Elevator system, which comprises:

at least one shuttle elevator, which serves at least one transfer level, which transfer level comprises at least one transfer floor;
at least two local elevators, the elevator cars of which are arranged to travel in the same elevator hoistwaysuch that the aforementioned elevator cars can serve at least one shared transfer floor of the aforementioned transfer level;
at least one destination call appliance;
a control system, which is arranged to receive destination calls given from a destination call appliance, to form a plurality of route alternatives according to the destination call from the departure floor to the destination floor, and to allocate the destination call to one or more elevators by selecting the best route alternative on the basis of a given optimization criterion, wherein when allocating a destination call the control system is arranged to take into account that the elevator cars of the local elevators that travel in the same elevator hoistway cannot simultaneously be at an aforementioned shared transfer floor in cases in which the route alternative comprises a part-trip with a local elevator and a change of elevator at the aforementioned shared transfer floor.

Method for allocating destination calls in an elevator system, which elevator system comprises:

at least one shuttle elevator, which serves at least one transfer level, which transfer level comprises at least one transfer floor;
at least two local elevators, the elevator cars of which are arranged to travel in the same elevator hoistway such that the aforementioned elevator cars can serve at least one shared transfer floor of the aforementioned transfer level,
and in which method:
a destination call given by a passenger is received;
a plurality of route alternatives according to the destination call is formed from the departure floor to the destination floor;
and
the destination call is allocated to one or more elevators by selecting the best route alternative on the basis of a given optimization criterion, wherein when allocating a destination call it is taken into account that the elevator cars of the local elevators that travel in the same elevator hoistway cannot simultaneously be at the same shared transfer floor in cases in which the route alternative comprises a part-trip with a local elevator and a change of elevator at the aforementioned shared transfer floor.
