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

Abstract

In the communication device (1), there is first of all a coil arrangement (2) with two oppositely positioned sub-configurations (3, 4), by means of which it is possible to generate between the two sub-configurations (3, 4). A communication field operating, and each of the two sub-configurations (3, 4) has at least two coils (5, 6, 7, 8), the communication device also has sub-configuration signal generating means (31) designed with The communication device is further provided with coil signal generating means (32) for distinguishably generating and transmitting the first sub-configuration signal (TI1) and the second sub-configuration signal (TI2) for each of the two sub-configurations (3, 4). ), which is designed to differentially generate and transmit coil signals for at least two coils (5, 6, 7, 8) of each sub-configuration (3, 4) according to the respective sub-configuration signals (TI1, TI2) (S1, S2, S3, S4).

Description

Invention field [0001] The present invention relates to a communication device that communicates with at least one data carrier, said data carrier being able to be introduced into the communication field of the communication device, and the communication device has a coil configuration with two relative sub-configurations, through which The configuration is capable of generating a communication field operating between two sub-configurations, and the communication device has a sub-configuration signal generating device, which is designed to distinguishably generate and transmit a first sub-configuration signal for corresponding one of the two sub-configurations And the second sub-configuration signal. [0002] The present invention also relates to a coil configuration for communicating with at least one data carrier, which data carrier can be introduced into a communication field generated with said coil configuration, said coil configuration having two opposite sub-configurations,...

AI Technical Summary

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
