Definitions

  • the required duration is made up of a transmission rate, waiting times as well as the duration of the individual transmissions and the number of transmissions necessary for communication. If access to the transponder is restricted by a key or cryptographic method, further operations are required to activate the transponder. As a result, time-critical access to, for example, sensor data from the sensor transponder can no longer be guaranteed.
  • a read-write device is therefore proposed which is configured to prepare communication or data transmission to a predetermined transponder in a separation phase using a communication protocol in order to communicate with the predetermined transponder in a data exchange phase following the predetermined separation phase, wherein the read-write device is configured to send a plurality of commands to the predetermined transponder in the predetermined data exchange phase before a next isolation phase begins.
  • the read-write device is configured to, for example, direct / transmit a command that may conform to ISO 18.000-6 to the transponder connected to it, as a result of which at least one further command is executed by the transponder, which, for example, results in the transmission of sensor data.
  • a transmission of a large number of, for example, sensor data without exchanging data or information for a further separation phase between the read-write device and the transponder enables a higher reading rate of the information of the transponder or a sampling rate of sensors of the sensor-transponder.
  • a data exchange phase is understood to mean data transmission or communication between a read-write device and at least one transponder.
  • transponder which is configured to be put into a command acceptance state by a read-write device in a predetermined isolation phase using a communication protocol, and to be able to use the read-write device in a data exchange phase following the predetermined isolation phase.
  • Device to communicate wherein the transponder is configured to process a plurality of commands from the read-write device in the predetermined data exchange phase.
  • the transponder connected to such a read / write device for example a sensor transponder, is able to execute more than one command or more than one value / data packet with the associated one Read-write device without having to initiate a new separation phase for each individual data packet.
  • the read-write device is configured to prepare communication to one or more predetermined transponders in one or more predetermined isolation phases using a communication protocol in order to be able to exchange data with the one or more predetermined transponders in a data exchange phase following the predetermined isolation phase Transponders to communicate, wherein the read-write device is configured to send a read command to the one or more predetermined transponders in the predetermined data exchange phase, and wherein the read command has no transponder address parameter to all of the one or more transponders address, or has a transponder address parameter that addresses a number from the one or more transponders via addresses that are shorter than transponder addresses that are used during the isolation phase, and / or where the read command does not have a read address parameter, for example a memory register of the memory of the transponder , having.
  • the transponder can be put into a state by means of an activation command of the read / write device in which it can receive and itself transmit commands without additional addressing or further abbreviated commands from the transponder in question.

  • At least one predetermined command of the plurality of commands is a read command
  • the transponder is configured to send a shortened response to the read / write device to the at least one predetermined command, which is shorter than responses to other read commands of the Read-write devices other than the predetermined command.
  • the predetermined read command corresponds to a release command that allows shortened responses for communication or data transmission between the read / write device and the transponder.
  • the shortened answers also represent a reduction in the amount of data transmitted or to be transmitted, which is reflected in the optimization of the data throughput.
  • the method according to an exemplary embodiment has no transponder address parameter or - only - one transponder address parameter for at least one predetermined command of the plurality of commands.
  • a higher data throughput can only be achieved with commands that are shortened in comparison to conventional commands that are used in the transmission between the read / write device and the transponder.
  • the more shortened commands are transmitted between two isolation phases in a transmission between a read-write device and a transponder connected to it, the more efficient the transmission. In other words, the efficiency increases when transmitting useful data relative to the number of transmitted data packets without address parameters.

Abstract

L'invention concerne un concept selon lequel un appareil de lecture-écriture (10) peut échanger de manière efficace des paquets de données avec au moins un transpondeur prédéfini (20). L'appareil de lecture-écriture (10) et le transpondeur (20) sont configurés de telle sorte que l'appareil de lecture-écriture (10) prépare une communication avec le transpondeur prédéfini (20) au moyen d'un protocole de communication (28) lors d'une phase de singularisation prédéfinie, afin de communiquer avec le transpondeur prédéfini (20) lors d'une phase d'échange de données suivant la phase de singularisation prédéfinie. L'appareil de lecture-écriture (10) et le transpondeur (20) sont configurés pour échanger, lors de la phase d'échange de données prédéfinie, une pluralité de paquets de données (50) avant le début d'une prochaine phase de singularisation.
