Abstract

The invention discloses an RFID (Radio Frequency Identification Devices)-based identification system. The RFID based identification system comprises a power supply, a microprocessor, an RFID transceiver chip, a radio frequency power amplifier, a first antenna, a second antenna, an RFID label, an RFID reader-writer and a single chip microcomputer, wherein the microprocessor, the RFID transceiver chip, the radio frequency power amplifier and the second antenna are sequentially connected in sequence; the first antenna is connected with the RFID transceiver chip; the power supply is connected with the microprocessor and the RFID transceiver chip; the RFID label is in wireless connection with the first antenna; the RFID reader-writer is in wireless communication with the second antenna; and the single chip microcomputer is connected with the RFID reader-writer. By adopting the RFID-based identification system, the application such as RFID real-time position is realized, the required quantity of the RFID reader-writers is greatly decreased, and the cost is saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an identification system based on RFID (Radio Frequency Identification, radio frequency identification). Background technique [0002] Radio frequency identification technology is a technology that uses radio frequency signals to realize wireless information transmission to the destination. The general RFID system includes electronic tags and RFID readers. The RFID readers communicate directly with the electronic tags. The electronic tags store the relevant information of the identified items, and the RFID readers realize the collection and upload of tag data. In this way, especially in real-time positioning, multiple RFID readers need to work together, which increases the corresponding cost. At the same time, due to the direct communication between the RFID reader and the electronic tag, it is not conducive to the expansion of the system, and the function is rela...
