Communication station for communication with transponders and further communication stations with the aid of different protocols

摘要

A communication station (1) is suitable for contactless communication with transponders and with further communication stations and has a first protocol-executing circuit (12) and a second protocol-executing circuit (13), the first protocol-executing circuit (12) being designed to effect communication between the communication station (1) and transponders under a station/transponder protocol and the second protocol-executing circuit (13) being designed to effect communication between the communication station (1) and further communication stations under a station/station protocol.

1. A communication station adapted for contactless communication with transponders and with further communication stations, comprising:
first protocol-executing means configured to function according to station-transponder protocol and to effect communication between the communication station and at least one transponder while observing the station-transponder protocol, the at least one transponder being a passive transponder that does not have any power supply of its own; second protocol-executing means configured to function according to a station-station protocol that differs from the station-transponder protocol in respect of at least one protocol parameter and to effect communication between the communication station and at least one further communication station while observing the station-station protocol; first signal-processing means electrically connected to the first protocol-executing means and configured to code and decode signals for contactless station-transponder communication and to modulate and demodulate the signals for the contactless station-transponder communication; second signal-processing means electrically connected to the second protocol-executing means and configured to code and decode signals for contactless station-station communication and to modulate and demodulate the signals for the contactless station-station communication; and a transmission coil electrically connected to the first and second signal-processing means such that the contactless station-transponder and station-station communications are performed inductively between the communication station and the at least one transponder and the at least one further communication station, wherein the first protocol-executing means have energy-supply signal generating means that are configured to generate an energy-supply signal each time the handling of the station-transponder protocol starts, and wherein the second protocol-executing means have synchronizing-signal generating means that are configured to generate a synchronizing signal each time the handling of the station-station protocol starts, the energy-supply signal for each handling of the station-transponder protocol and the synchronizing signal for each handling of the station-station protocol being transmitted through the transmission coil, the synchronizing signal being transmitted to the further communication stations for synchronization of quartz oscillators in the further communication stations to process subsequent signals between the communication station and the further communication stations.
