Abstract
Elevator system passengers are transported in one or more of a plurality of elevator cars. The elevator cars can require different amounts of energy to operate. Passenger trips can be allocated to one car or another car based on the expected energy consumption for the trips in one or the other car.
Claims10
An elevator operation method comprising:
- receiving elevator call information for one or more elevator trips;
- allocating the one or more elevator trips for service among a first elevator car and a second elevator car, the allocating being based on expected energy consumption for the first elevator car and expected energy consumption for the second elevator car, the expected energy consumption for the first elevator car being based on a weight of the first elevator car or a passenger capacity of the first elevator car, and the expected energy consumption for the second elevator car being based on a weight of the second elevator car or a passenger capacity of the second elevator car;
- and
- operating the first and second elevator cars according to the allocation of the one or more elevator trips;
- wherein:
- the expected energy consumption for the first elevator car is based on the weight of the first elevator car, the expected energy consumption for the second elevator car is based on the weight of the second elevator car, and the first elevator car is heavier than the second elevator car, or
- the expected energy consumption for the first elevator car is based on the passenger capacity of the first elevator car, the expected energy consumption for the second elevator car is based on the passenger capacity of the second elevator car, and the first elevator car has a larger passenger capacity than the second elevator car.
4 more elements
An elevator installation comprising:
- a first elevator car disposed in a first elevator shaft;
- a second elevator car disposed in a second elevator shaft;
- and
- an elevator control unit, the elevator control unit being configured to receive elevator call information for one or more elevator trips, and to allocate the one or more elevator trips for service among the first elevator car and the second elevator car, the allocating being based on expected energy consumption for the first elevator car and on expected energy consumption for the second elevator car, the expected energy consumption for the first elevator car being based a weight of the first elevator car or a capacity of the first elevator car, and the expected energy consumption for the second elevator car being based on a weight of the second elevator car or a capacity of the second elevator car;
- wherein the first elevator car is heavier than the second elevator car, the first elevator car has a larger capacity than the second elevator car, or the first elevator car comprises a double-deck car and the second elevator car comprises a single car.
2 more elements
One or more computer-readable storage media having encoded thereon instructions which, when executed by a processor, cause the processor to perform a method, the method comprising:
- receiving elevator call information for one or more elevator trips;
- and
- allocating the one or more elevator trips for service among a first elevator car and a second elevator car, the allocating being based on expected energy consumption for the first elevator car and expected energy consumption for the second elevator car, the expected energy consumption for the first elevator car being based on a weight of the first elevator car or a passenger capacity of the first elevator car, and the expected energy consumption for the second elevator car being based on a weight of the second elevator car or a passenger capacity of the second elevator car;
- wherein the first elevator car is heavier than the second elevator car, the first elevator car has a larger capacity than the second elevator car, or the first elevator car comprises a double-deck car and the second elevator car comprises a single car.
