    Abstract
  • To identify multiple objects simultaneously assuming that the number of labels is not known in advance, multiple objects anti-collision RFID(radio frequency identification) technology and its application system model were presented. The collision solution in ISO/IEC15693 standard was improved, with the self-match mode in address access policy and the dynamic slot allocation. These were used to solve collision problem and approach the expected target during identifying process. A method was discussed to determine and optimize the system parameters. Based on the model and the cycle of anti-collision identification, a system was developed and applied in a project of smart management system in library. The results of experiment indicate that the identification performance is more effectively and accurately. This technology can satisfy more requirements and its application range is still extended.
