  • Patent number: 7740111
    Abstract: An elevator group control system for controlling multiple elevators cars each of which serves a plurality of floors includes a route preparation section which, at a time of assigning a hall call to one of the elevator cars, calculates a future trajectory for each of the elevator cars. The future trajectory for each elevator is for a case in which the hall call is assigned to the elevator car. A selecting unit which determines a selected one of the elevator cars to which the hall call is to be assigned using the calculated future trajectories.

  • Patent number: 7730999
    Abstract: An elevator group control system includes a reference route generating portion, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and an assignment portion which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Reference routes which guide the cage's trajectory into temporally equal interval condition are generated, and car assignment is executed to allow the cages to settle in temporally equal interval condition over a long period of time.

  • 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.

  • Patent number: 7426982
    Abstract: An elevator group control system is provided which stably keeps cage's position in temporally equal interval condition over a long period of time. The present invention provides a system comprising: reference route generating means, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and assignment means which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Since reference routes which guides the cage's trajectory into temporally equal interval condition are generated and car assignment is executed so as to make the respective cages follow their reference routes, it is possible to allow the cages to settle in temporally equal interval condition over a long period of time.

  • Patent number: 6408986
    Abstract: An elevator capable of supplying electric power to accessory hall devices such as up/down elevator buttons and position indicators without requiring power supply lines between the cage and each hall. A drive battery which supplies electric power to hall devices provided in each hall and a receptor connected to the battery are provided on the hall. A feeder contactable with the respective receptors, a charging device that charges the battery via the feeder and receptor are provided on the top of the cage. When the charging voltage, for example, used in a hall of the floor drops below a predetermined voltage value, the cage stops automatically at the floor and the charger charges the drive battery in the hall of the floor via the receptors and feeder.

  • Patent number: 5892190
    Abstract: Elevator group supervisory control method and system for group supervisory control of a plurality of elevators serving a plurality of floors. The method and apparatus of the invention permits the inputting of qualitative requests (guidance), from the user, concerning elevator operation into the group supervisory control system. Qualitative requests concerning elevator operation are set in the form of guidance (or request) targets. The thus set request targets are converted into control targets for the elevators. Actual group supervisory control is executed using the control targets.
