Abstract: A method and a system for entering a destination floor call, for storing the call data of a destination floor call entered by the user, for allocating an elevator car to the user on the basis of the landing call data of the destination floor call and for transmitting a car call to the elevator car when the elevator is arriving at the landing. In the method, the user inputs a destination floor call using a destination call device. The destination floor call can be stored in the memory of the destination call device, in which case the call data transmitted to the control system comprises only the landing call, i.e. information specifying the user's starting floor and whether the destination floor given by the user is in the upward or downward direction. The destination floor call can also be transmitted directly to the elevator control system, which stores the call data of the destination floor call in the memory of the control system.

Abstract: 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.

Abstract: 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 full 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.

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: A method controls the elevators in an elevator group when destination floor call input is used and the traffic within the elevator group is to be optimized. According to the concept of the method, based on traffic intensity, a cost function is optimized by changing the number of cost criteria from one to several and back and weighting the criteria in different ways in the aforesaid cost function.

Abstract: Method for controlling the elevators in an elevator bank in a building divided into zones has a plurality of floors via a process whereby destination floor calls are issued to the elevators by destination floor call input devices in the lobby of departure and the calls are distributed internally among different zones in the building by the elevator group control system, the elevators and the floors to be served being divided dynamically within the aforesaid elevator group control system into aforesaid zones, varying the numbers of elevators and the zone limits (r) according to traffic forecasts and transportation need.

Abstract: A procedure for controlling an elevator group consisting of double deck elevators consists of allocating landing calls to elevators and elevator decks in such a way that passenger journey time is optimized. The time of the call and the estimated time of arrival to destination floor are taken into account. Passenger flow and elevator status within the elevator group are monitored and passenger wait time and arrive time estimated based thereon. The best elevator is selected to minimize passenger wait and ride time. The best deck is further selected based on the estimated wait time and ride time to minimize passenger journey time.

Abstract: As elevator group including at least two elevator cars is controlled using a group control unit which allocates the calls to different elevators. Based on statistical data and/or statistical forecasts, virtual passenger traffic is generated and used in a simulation that creates events in the virtual passenger traffic, on the basis of which an elevator-specific cost is computed for each call to be allocated. Based on the costs, the best elevator is selected to serve the call. This allocation of a best elevator to answer a specific landing call may be reallocated as the simulation is updated to update the best elevator to answer a specific floor call.

Abstract: The invention relates to a procedure for controlling an elevator group consisting of double-deck elevators. According to the invention, landing calls are allocated to the elevators and after that to the elevator decks in such a way that the passenger journey time is optimised. The procedure of the invention takes into account the time the call has been on and the estimated time of arrival to the destination floor.

Abstract: A method for controlling an elevator group of double-deck elevators. Landing calls are allocated to the elevators and elevator decks in such a way that the passenger journey time is optimized. The method takes into account the current landing call time and the estimated time of arrival to the destination floor. The method minimizes passenger journey time by allocating the landing call to the deck that will cause the fewest additional stops to the elevator and least additional delay on the way to the passenger destination floor. In addition, the elevator estimated time of arrival to a destination floor is calculated separately for each deck, taking into account the stops already existing for the elevator and the additional stops caused by the selected landing call. Further the landing call is allocated to the deck for which the estimated time of arrival to the destination floor is least. In addition, the best deck for each landing call is selected by minimizing a cost function.

Abstract: The invention relates to a procedure for controlling an elevator group. According to the invention, the landing calls issued from different floors are weighted by a floor-specific weight factor. The weighted call time is utilized in the calculation of the serving time of the calls and for the selection of the best elevator to serve a landing call.

Abstract: Procedure for determining the number of passenger transfers in an elevator car on the basis of car load data. The procedure of the invention includes continuous measurement of the car load during stoppage, filtering of the measurement data, recording of the load changes taking place during stoppage, and determination of the number of persons having entered or left the elevator car, based on said changes. The device contains an A/D converter for converting the load data into digital form, and a recording and calculation unit placed in the elevator control system and connected to the output of the A/D converter to detect and count the changes in the load.

Abstract: A method for controlling an elevator group in which statistical data on a traffic flow within an elevator group, representing the times, local and total volumes of the traffic, and a number of different traffic types used in a group control are stored in a memory unit belonging to the control system. The traffic flow is divided into two or more traffic components, the relative proportion or different traffic components and the prevailing traffic intensity are deduced from the traffic statistics, the traffic components and traffic intensity, i.e. the traffic factors, are subjected to assumptions whose validity is described by means of membership functions of the factors. A set of rules which correspond to different traffic types are formed from these factors and are assigned values by means of the factors and membership functions, the rule which best describes the prevailing traffic is selected, and the traffic type corresponding to the selected rule is used in the control of the elevator group.
