Abstract:
The invention relates to an elevator installation and also to a method for controlling elevators. In the method a run plan is formed for driving elevator cars on the basis of service requests, the elevator cars are driven according to the run plan, by supplying electric power via the electricity distribution network of the building to a hoisting machine driving an elevator car, and also by supplying electric power from a hoisting machine braking an elevator car back to the electricity distribution network of the building, alternatives for a run plan are formed for driving elevator cars on the basis of service requests, the electric power which the hoisting machines need for implementing the aforementioned alternatives is determined, and also a run plan is selected for use from the plurality of different alternatives, when implementing which run plan the electric powers of the hoisting machines, when summed together, smooth the power variation occurring in the electricity supply of the building.
Abstract:
According to an embodiment there is provided a building automation system control apparatus comprising building automation system control logic configured to receive signaling from entities connected to a building automation system and to cause transmission of control signaling to the entities connected to the building automation system, wherein the building automation system control logic comprises elevator control logic as an integral part to directly control an elevator system comprising one or more elevators, the building automation system control logic being configured to take into account signaling received from the entities connected to the building automation system when determining control signaling for the elevator system; and the building automation system control logic being configured to take into account signaling received from the elevator system when determining control signaling for the entities connected to the building automation system.
Abstract:
The invention refers to a group control of an elevator group comprising several elevators, which group control comprises a destination control system with at least one destination call panel for issuing a first destination call by inputting a first destination floor whereupon the destination control system allocates said first destination call to a first elevator of said elevator group. The destination call panel has a link actuator, which, upon activation, initiates the destination control system to receive at least a second destination call with a second destination floor and/or departure floor, which second destination call is also allocated to said first elevator by the destination control system. By this measure passengers with different departure and/or destination floors can travel with the same elevator.
