Workflow Of RFID System

The RFID system has a basic workflow. From the workflow, it can be seen that the RFID system uses wireless radio frequency to conduct non-contact two-way data transmission between the reader and the electronic tag, in order to achieve target identification, data transmission, and control purposes. The general workflow of the RFID system is as follows:
① The reader/writer transmits radio frequency signals of a certain frequency through a transmitting antenna.
② When an electronic tag enters the working area of the reader/writer antenna, the electronic tag antenna generates sufficient induced current, and the energy obtained by the electronic tag is activated.
③ The electronic tag transmits its own information through a built-in antenna.
④ The reader/writer antenna receives a carrier signal sent from the electronic tag.
⑤ The reader/writer antenna transmits the carrier signal to the reader/writer.
⑥ The reader/writer demodulates and decodes the received signal, and then sends it to the high-level system for relevant processing.
⑦ The system high-level judges the legitimacy of the electronic label based on logical operations.
⑧ The upper level of the system makes corresponding processing for different settings, sends out command signals, and controls the action of the actuator.
