| Abstract: | A radio frequency identification device is designed based on coupling coil. The system consists of the reader and the responder. The reader is composed of PT2272, coupling coil and LEDs, and the responder of PT2262, coupling coil and dial switches. A single power supply is used and the energy of transponder is all from the coupling coil. Asynchronous serial communication and load modulation are adopted in wireless data transmission. The reader can identify adjacent transponders and display the recognition results with an identification distance greater than 10 cm, an identification rate higher than 95% and a response time is better than 1 s. |
