Communication device with coil configuration for the communication with stationary data carriers

Abstract

In a communication device (1) with firstly a coil configuration (2) which has two oppositely situated sub-configurations (3, 4), by means of which a communication field operative between the two sub-configurations (3, 4) can be generated and each of the two sub-configurations (3, 4) having at least two coils (5, 6, 7, 8), and with secondly sub-configuration signal-generating means (31) which are designed for the distinguishable generation and delivery of a first sub-configuration signal (TI1) and a second sub-configuration signal (TI2), for each of the two sub-configurations (3, 4), there areprovided thirdly coil signal-generating means (32) which are designed for the distinguishable generation and delivery of coil signals (S1, S2, S3, S4) for the at least two coils (5, 6, 7, 8) of the respective sub-configuration (3, 4) on the basis of the respective sub-configuration signal (TI1, TI2).

Description

technical field [0001] The invention relates to a communication device that communicates with at least one data carrier that can be introduced into the communication field of the communication device and that has a coil configuration with two opposing sub-configurations through which configuration capable of generating a communication field operating between two subconfigurations, and the communication device has subconfiguration signal generating means designed to differentially generate and transmit a first subconfiguration signal for a respective one of the two subconfigurations and the second sub-configuration signal. [0002] The invention also relates to a coil arrangement for communicating with at least one data carrier, which can be introduced into a communication field generated with said coil arrangement, said coil arrangement having two opposing subconfigurations by means of which a A communication farm that operates between two subconfigurations.

Problems solved by technology

[0007] With known communication devices there is a problem that the communication field has a central area in which, depending on the orientation of the transponder, an unfavorable field distribution of the communication field predominates; this makes communication with the transponder virtually impossible, the transponder The communication coils of have an unfavorable orientation of the coil plane parallel to the xy-plane or parallel to the xz-plane, since in the central zone transponders with one of these orientations cannot be powered and thus cannot communicate

For goods present in packages on fixed pallets located in this central area, there is thus a problem that these goods cannot be registered fully automatically by contactless methods using communication equipment, which requires considerable additional work effort, such as repeated movement Pallets, for example or require considerable construction costs, such as supplies like transferable coil arrangements, or conveyor belts for moving the pallets
