  • Patent number: 8397874
    Abstract: An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators.
    Type: Grant

  • Patent number: 8151943
    Abstract: A method of controlling an intelligent destination elevator control system streamlines the control of two or more destination elevators. Operations of a group of destination elevators are monitored to gain experience about how the population is served by the group of destination elevators that serves a building or a building zone. The analysis of measured and/or modeled data and conditions with data about traffic patterns and traffic characteristics enables the system to dynamically control the destination elevators. The system may enhance passengers' experience through efficiency and/or with an improved comfort level.

  • Publication number: 20090050417
    Abstract: An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators. A time-table and target elevator service quality parameters may be selected to control destination elevators according to one or more customer selectable mode of operation parameters. The data structure may be processed to control UP and/or DOWN transportation capacities of the destination elevators while satisfying the one or more customer selectable mode of operation parameters. Some intelligent destination elevator control systems may control when elevator cars of a group service the floors of a building.
