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.

Dependent claims

An elevator installation having a plurality of elevators comprising:

a recognition device for recognizing elevator calls entered at an entry location by an information transmitter carried by an elevator user, initializing the entry location as a starting floor of a journey;
a control device receiving the recognized elevator call and allocating an elevator to respond to the elevator call, through a predetermined allocating algorithm;
a call acknowledging device comprising one of a display device and an acoustic device to acknowledge recognition of the elevator call and to communicate a proposed destination floor to the elevator user;
the recognition device, mounted in the access area in the vicinity of the elevators and spatially located away from elevator doors, actuating the information transmitter and comprising a unit that independently reads data transmitted from the information transmitter carried by the elevator user and a storage device coupled between the unit and the control device:
the recognition device one of transmitting proposed destination floor data, based upon the data transmitted from the information transmitter, to the control device, and, transmitting elevator user specific data. based upon individual features of the elevator user stored in the storage device, to the control device.
