Abstract
Described herein is a system and method for the continuous operation of an RFID communication system in a user-friendly manner and to ensure the reliability thereof in a cost-effective manner by uploading and storing configuration data from each active reader into a memory of the management system. A control unit polls an activity status for each active reader at regular time intervals. In the event of an active reader failing, the control unit identifies the failed reader, loads the configuration data for the failed reader from a memory into a specified inactive reader, and activates the specified inactive reader in place of the failed reader to identify the at least one RFID transponder.
Claims24
A radio frequency identification (RFID) communication system, which comprises:
- at least one active reader for identifying at least one RFID transponder, and at least one inactive reader, wherein the RFID communication system also comprises a management system, which comprises the following:
- at least one management data bus, via which the management system is in bidirectional data communication with the readers;
- at least one memory for uploading and storing configuration data from each active reader;
- at least one control unit
- for polling an activity status for each active reader at regular time intervals,
- in the event of an active reader failing, for identifying the failed reader and loading the configuration data for the failed reader from the memory into a specified inactive reader, and
- for activating the specified inactive reader in place of the failed reader to identify the at least one RFID transponder.
A method for controlling radio frequency identification (RFID) communication system comprising an active reader, which is suitable for identifying at least one RFID transponder, and comprising at least one inactive reader, wherein the method comprises the following steps:
- uploading and storing configuration data from each active reader into a memory of the management system;
- a control unit polling an activity status for each active reader at regular time intervals and
- in the event of an active reader failing, identifying the failed reader and loading the configuration data for the failed reader from the memory into a specified inactive reader;
- and
- activating the specified inactive reader in place of the failed reader to identify the at least one RFID transponder.
