<p>A passive ultra-high frequency RFID tour guide system and an operating method, employing ultra-high frequency RFID technology to implement tour guiding and management at attractions or at a large exhibition halls. The tour guide system comprises a handset control system and an electronic tag. The electronic tag is a passive electronic tag. When the presence of the electronic tag is identified by the handset control system, same begins to read ID number data of the electronic tag, and transmits the ID number data to an MCU control unit. The MCU control unit transmits the received ID number data to an audio decoding unit. The audio decoding unit begins to search in an SD card for an audio file corresponding to the ID number data, and, after decoding, broadcasts an analog stereo audio signal to a stereo audio output device. The tour guide system is convenient to use, reduced in costs, and easy to maintain, and provides a great reading distance and rapid identification speed.</p> |
