Abstract
According to an aspect, there is provided a method for elevator call allocation in an elevator system. The method comprises receiving charge information associated with an energy storage of an elevator car from each of a plurality of elevator cars of the elevator system; receiving an elevator call to a floor providing a charging arrangement for the energy storages; and allocating the elevator call to an elevator car of the plurality of elevator cars at least partly based on the charge information received from each of the plurality of elevator cars.
Claims14
A method for elevator call allocation in an elevator system, the method comprising:
- receiving charge information associated with an energy storage of an elevator car from each of a plurality of elevator cars of the elevator system;
- receiving an elevator call to a floor providing a charging arrangement for the energy storages;
- and
- allocating the elevator call to an elevator car of the plurality of elevator cars at least partly based on the charge information received from each of the plurality of elevator cars,
- wherein the charge information comprises at least one of a charge level and a cell imbalance of the energy storage of each of the elevator cars, wherein the method further comprises:
- determining that the charge level of an energy storage of an elevator car is below a second threshold level;
- taking the elevator car out of service;
- and
- controlling the elevator car to travel to a landing floor having a charging arrangement to charge the energy storage of the elevator car.
An elevator group controller comprising:
- means for receiving charge information associated with an energy storage of an elevator car from each of a plurality of elevator cars of the elevator system;
- means for receiving an elevator call to a floor providing a charging arrangement for the energy storages;
- and
- means for allocating the elevator call to an elevator car of the plurality of elevator cars at least partly based on the charge information received from each of the plurality of elevator cars,
- wherein the charge information comprises at least one of a charge level and a cell imbalance of the energy storage of each of the elevator cars,
- wherein the elevator group controller further comprises:
- means for determining that the charge level of an energy storage of an elevator car is below a second threshold level;
- means for taking the elevator car out of service;
- and
- means for controlling the elevator car to travel to a landing floor having a charging arrangement to charge the energy storage of the elevator car.
An elevator group controller comprising:
- means for receiving charge information associated with an energy storage of an elevator car from each of a plurality of elevator cars of the elevator system;
- means for receiving an elevator call to a floor providing a charging arrangement for the energy storages;
- and
- means for allocating the elevator call to an elevator car of the plurality of elevator cars at least partly based on the charge information received from each of the plurality of elevator cars,
- wherein the elevator group controller further comprises:
- means for determining that a charge level of an energy storage of an elevator car is below a first threshold level;
- means for determining that the received elevator call is associated with a landing floor having a charging arrangement to charge energy storages of elevator cars;
- means for allocating the elevator call to the elevator car having the charge level below the threshold level to enable charging of the elevator storage at the landing floor;
- means for determining that the cell imbalance of an energy storage of an elevator car exceeds a third threshold value;
- means for taking the elevator car out of service;
- and
- means for controlling the elevator car to travel to a landing floor having a charging arrangement to balance the energy storage of the elevator car.
