Abstract:
The invention relates to a method for allocating an elevator (120A, 120B, 120C; 130A, 130B; 140A, 140B, 140C) in an elevator system (100), the elevator system (100) comprising elevator groups (120; 130; 140), each group (120, 130, 140) comprising elevators, the elevator groups are formed based on a load unbalance of the elevators, the method comprises: detecting (210) received service calls in a predefined time window; evaluating (220) a number of passengers requesting service based on the received number of service calls; selecting (230), based on the evaluated number of passengers, an elevator group to serve the floor; and allocating (240) an elevator belonging to the selected elevator group to provide service. The invention also relates to an apparatus, an elevator system, and a computer program.
Abstract:
According to one aspect, there is provided a method for controlling an elevator group comprising at least a first elevator (202) and a second elevator (210), wherein a counterweight balance of the first elevator (202) differs from a counterweight balance of the second elevator (210), the method comprising: controlling the elevator group comprising at least the first elevator (202) and the second elevator (210); determining threshold loads for the first (202) and second elevator (210) separately for up and down direction, a threshold load being dependent of the counterweight balance of the corresponding elevator, wherein the threshold load being a load for which consumed energy per up-down run is approximately zero; and controlling, when allocating an elevator in response to a destination call, route determination for the first (202) and second elevator (210) comprises minimizing a load difference from the threshold loads.
Abstract:
The present invention relates to a solution for allocating an elevator car in an elevator system. In the solution a destination call is received from a user and an elevator car is allocated to the user on the basis of the destination call received. The invention is characterized in that in conjunction with a destination call a categorization expression is received from the user, and in that the categorization expression given by the user is taken into account in allocating an elevator car.
Abstract:
Modern large buildings and public places are equipped with a plurality of elevators, exits and points of interest for fluent movement. The passenger flows in a building or public place can be traced and modelled by using statistics and in- formation regarding current state of the modelled building or public place. The information derived from this model can be used for controlling elevators, escalators and similar in the building more efficiently. The same information may be used also for guiding passengers in the building or public place to use other transportation means so that the duration high traffic situation can be reduced or sometimes completely avoided.
Abstract:
The present invention discloses a solution for controlling an elevator system, which elevator system comprises at least one elevator (A,B,C,D), call-giving appliances (109) in the elevator lobbies, and also means for detecting in the desired identification area contact patterns directed onto the floor surface of at least one elevator lobby. A user to be connected to a call given from the elevator lobby is classified on the basis of the contact pattern produced by the user (105, 107, 108), the type data of the call is connected to the call on the basis of the classification, and the call with its type data is transmitted to the control system (110) of the elevator system for controlling the elevators.
Abstract:
The present invention discloses a method and a system for serving user groups in an elevator group in which the floors to be served are divided into floor zones. Passengers are classified on the basis of call information and determined classification rules into user groups, an elevator car is allocated to each passenger and the calls addressed to each elevator car are served one user group at a time.
Abstract:
A set of elevators, e.g. an elevator group, is connected to a common power supply. The elevators are controlled by a common control system so that an elevator car having stopped is prevented from being dispatched in the up direction if, of the elevator cars of the elevators connected to the common power supply, more cars are moving upwards than are moving downwards .
Abstract:
The invention relates to an elevator system comprising: a plurality of elevator sub-systems (110; 150) and a group controller (170) configured to control the plurality of the elevator sub-systems (110; 150), wherein the group controller (170) is configured to: determine an efficiency of the elevator system; and control, in accordance with the efficiency of the elevator system, at least one elevator sub-system (110; 150) to serve elevator calls at different zones from at least one other elevator sub-system (110; 150). The invention also relates to a method, a group controller and a computer program product.

Abstract:
The invention concerns a method for a passenger-allocation in a multi-deck elevator group, the decks of which defining elevator cars, respectively, being stacked above each other and being mounted in a car frame to be moved synchronously in an elevator shaft. The method is performed by a control unit to dispatch the elevator cars for serving any passenger call which can be entered as a landing call or a car call, wherein a call can create a number of allocation proposals calculated by means of an optimization algorithm carried out by the control unit for dispatching an elevator to a passenger call. The invention is characterized in that said allocation proposals are then processed in a routing algorithm defining one serving deck to be taken for the allocation of a specific call, which routing algorithm is restarted either for any further incoming call independent of whether said further incoming call is creating new elevator allocation proposal(s) or when a reallocation timeout has passed. The invention further relates to a computer program carrying out the inventive method.
