System und Verfahren zur Kommunikation mit an Objekten anbringbaren Transpondern sowie Verwendung des Systems

DE 102006047356 B3 UPAB: 20080501 NOVELTY - The system has a reading device (4) including transmission/reception device (5) with an antenna (6), and a border strip (1) defining a selection area for the admission of objects e.g. goods (2), which is provided with a metallic screen. The antenna is arranged within or to the border strip. A device (7) is provided for changing field distribution produced by the antenna in the area, where the distribution distorts electromagnetic waves in the area such that occurrence of standing waves is prevented. The device (7) is formed such that the device (7) changes the position of the antenna. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for communication with transponders that are attached to objects. USE - System for communication with a transponder that is attached to an object e.g. commodities and goods, for transporting, covering, storage of good units, in conveyance or technical system with which the objects are conveyed or produced, and in sales room or presentation rooms (all claimed). Can also be used in conveyance or technical plants, for input goods-output goods, in particular for pallets with metal containers, pallet stacks of a covering knot or a pallet, in material handling engineering, in quality management e.g. scanning of a technical system in the presence of transponders by surrounding a metallic covering, scanning of a mobile system e.g. vehicle, by positioning in a metallic reflecting area or by moving a metallic reflecting area to transponders, in logistics as mobile application e.g. transportation area of a metal container, unit load device (ULD) for aviation, transportation area on a laminar transportation device, transportation area of a body of a vehicle e.g. trolley, fork-lift truck, railway car, food container and within a sales area e.g. goods shelf, with automatic stock control. ADVANTAGE - The device is provided for changing field distribution produced by the antenna in the area, where the distribution distorts electromagnetic waves in the area such that occurrence of standing waves is prevented, thus increasing communication quality by the maximization of quasi coincidentally distributed field configurations of electromagnetic waves in the querying and/or selection area for the transponders. The border strip can be designed as transportation carriers, so that idealized constant communication characteristics can be created in relation to external influences, and minimizing radiation exposure for the environment
