Publication number: 20140124302Abstract: The present invention discloses a solution for allocating hall calls in an elevator system, which comprises call input devices for registering hall calls at the floors, a group control system responsive to said hall calls, and a number of elevators controlled by elevator-specific elevator controllers on the basis of commands issued by the group control system. A number of route alternatives are generated on the basis of the calls active, and allocation calculation is decentralized by calculating elevator-specific cost terms associated with the route alternatives in the elevator controllers. The cost terms are returned to the group control system, which allocates the hall calls to the elevators according to the route alternative giving the lowest allocation cost.Type: ApplicationFiled: January 9, 2014Publication date: May 8, 2014Applicant: KONE CORPORATIONInventors: Janne SORSA, Marja-Liisa SIIKONEN

Patent number: 8132652Abstract: An elevator system includes 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 includes a part-trip with a local elevator and a change of elevator at a shared transfer floor.Type: GrantFiled: May 6, 2011Date of Patent: March 13, 2012Assignee: Kone CorporationInventors: Harri Hakala, Marja-Liisa Siikonen, Janne Sorsa, Henri Hakonen

Patent number: 7913819Abstract: A set of elevators includes a plurality of elevators without counterweight, a power supply, and a common control system. The plurality of elevators has a common connection to the power supply. The common control system includes one or more instructions to prevent or delay dispatch of an elevator car stopped at a floor if, at that instant, within a set period of time, or at that instant and within the set period of time, power consumed from an associated electrical network by the set of elevators or fed into the associated electrical network by the set of elevators together exceeds a set value. A method for controlling a set of elevators includes determining whether power consumed together exceeds a set value, and when the power consumed exceeds the set value, then departure of a next elevator car to be dispatched is prevented or delayed.Type: GrantFiled: June 11, 2009Date of Patent: March 29, 2011Assignee: Kone CorporationInventors: Marja-Liisa Siikonen, Janne Sorsa, Esko Aulanko

Patent number: 7694781Abstract: A method for allocating destination calls in an elevator system, the system including at least one multi-deck elevator, where the passenger gives his/her destination floor by means of a destination call device at the beginning of the journey route, thereby defining the staffing point and final point of the passenger's journey route in the elevator system. The method includes the steps of generating possible route alternatives from the staffing point to the final point of the journey route, determining a cost function containing at least one travel time term, determining the value of the travel time term corresponding to each route alternative in the cost function, calculating the total cost of each route alternative by using the cost function, allocating for the passenger the route alternative that gives the minimum total cost, and guiding the passenger to a waiting lobby and/or elevator consistent with the route alternative allocated.Type: GrantFiled: December 19, 2008Date of Patent: April 13, 2010Assignee: Kone CorporationInventors: Janne Sorsa, Marja-Liisa Siikonen

Publication number: 20090250298Abstract: 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.Type: ApplicationFiled: June 11, 2009Publication date: October 8, 2009Inventors: Marja-Liisa Siikonen, Janne Sorsa, Esko Aulanko

Patent number: 7594564Abstract: The present invention discloses a method, a system and a computer program for the effective evacuation of a building in an emergency, in which at least one elevator can be used as an evacuation aid. In the method the group control of the elevators monitors the numbers of people on the different floors of the building. The floor on which it is assumed are most people is set at each moment of monitoring for a greater priority in an evacuation situation. Taking into account the limited supply power a free elevator car is directed to the floor of the greatest priority, at which the elevator is filled. The full elevator is directed without stopping to the exit floor of the building. The system monitors by means of detectors the safety of the different parts of the building and directs people if necessary to a safe evacuation location to wait for an elevator. A so-called Traffic Forecaster can be used as an aid in defining the priorities.Type: GrantFiled: July 2, 2008Date of Patent: September 29, 2009Assignee: Kone CorporationInventors: Marja-Liisa Siikonen, Janne Sorsa, Jukka-Pekka Sarjanen, Kim Bärlund

Patent number: 7588126Abstract: In the method of the present invention an evacuation mode is presented in an elevator system, which receives destination calls i.e. operates in accordance with so-called destination control. In the method the destination floor calls given on the evacuation floors of the building are changed in the event of an exceptional incident such that the destination floor becomes an exit floor of the building. In the method the elevator car is filled as flail as possible on one floor and the travel time to the exit floor is minimized by directing the elevator car to the escape floor without intermediate stops. The passengers to be evacuated are shown information relating to the evacuation on a display located on the destination call panel and/or inside the car of the evacuation elevator.Type: GrantFiled: March 26, 2008Date of Patent: September 15, 2009Assignee: Kone CorporationInventors: Marja-Liisa Siikonen, Kim Bärlund

Patent number: 7559407Abstract: A set of elevators, preferably an elevator group, may include a number of elevators without counterweight which have a common connection to a power supply. The elevators may have a common control system which contains an instruction to prevent an elevator having stopped at a floor from being dispatched upwards if, of the elevator cars of the other elevators connected to the same power supply, more cars are moving upwards than are moving downwards at the instant and/or within a set period of time. A method for controlling a set of elevators without counterweight connected to a common power supply may include monitoring to establish whether, at the instant and/or within a set period of time, the number of upwards moving elevator cars of the elevators in the set is larger than the number of downwards moving elevator cars of the elevators in the set.Type: GrantFiled: August 27, 2007Date of Patent: July 14, 2009Assignee: Kone CorporationInventors: Marja-Liisa Siikonen, Janne Sorsa, Esko Aulanko
