Abstract
Elevator installation. This device enables an implicit input of destination calls in elevator installations, with an information transmitter, after a corresponding enquiry, sending data to a recognition device, wherein the data can contain direct information about the desired destination floor or serve for the identification of the elevator user and thus enable access to the information, filed in a storage device, about the destination floor, with the storage device being accommodated in a processing unit of an elevator control. The communication between the recognition device and the information transmitter takes place via radio frequencies and with the aid of the obtained data, the destination floor is determined in the processing unit and conveyed to the lift control, with the allocation being communicated to the passenger on a display device, with the process of the call entry taking place automatically, contactless and independent of the orientation of the information transmitter, i.e. it need not be visible for the recognition device, with an input device being provided for changing the floor that is proposed by the processing unit.
