Abstract
An elevator system in which hall calls from an independent inconspicuous riser (IR) are handled by the same dispatcher as hall calls from the normal hall call riser. Each floor of the building is assigned its own unique timing scan slot position for detecting normal hall calls, with the number of scan slots being at least twice the number of floors in the building. IR calls appear in scan slot positions for floors which are not in the actual building, and the dispatching function treats the building as though it had twice its actual number of floors. A car on IR duty translates its advanced car position into the imaginary portion of the building, before sending its advanced position signal to the dispatching function. When a car on IR duty receives an assignment from the dispatching function, its associated car controller translates an assignment for a fictitious floor to an actual floor of the building, and it utilizes its actual advanced car position in the process of serving the IR call.
