介紹一種簡單射頻識別系統設計。該設計包括閱讀器、應答器和線圈3部分。由單片機控制閱讀器向應答器發射無線信號，并接收應答器回送的信號，再通過分析回送信號識別物品。閱讀器和應答器之間以半雙工通信方式通信。
Abstract:
A simple design of radio frequency identification system is given in this paper.The design includes reader,responder and winding.Through MCU，signals are sent to responder from reader，then corresponding signals are sent back. According to the analysis of the signals sent back，the objects can be identified.Half-duplex communication is adopted? between? reader? and? responder.
