Abstract
An exemplary elevator input device includes a passenger interface configured to allow a passenger to place a call to indicate a desired elevator service. The elevator input device includes a controller configured to interpret any passenger input regarding desired elevator service. The controller identifies which of a plurality of elevator cars will be able to provide the desired elevator service according to a predetermined criterion. The plurality of elevator cars considered by the controller includes every elevator car that is capable of serving the call. The controller is also configured to assign the call to the identified elevator car. With the input device controller assigning the call to an identified elevator car, the dispatching of elevator cars is distributed among controllers of input devices rather than being accomplished at a single group controller.
