  • Patent number: 7594564
    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.

  • Patent number: 7562746
    Abstract: A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.
