Abstract

The invention discloses a passive ultrahigh frequency RFID (Radio Frequency Identification Devices) tour guiding system and an operation method. The tour guidance and the management of scenic spots or large exhibition halls can be realized by adopting the ultrahigh frequency RFID technology. The tour guiding system comprises a handset control system and an electronic tag, wherein the electronic tag is a passive electronic tag; when identifying the existence of the electronic tag, the handset control system starts to read ID number data of the electronic tag, and transmits the ID number data to an MCU (Microprogrammed Control Unit); the MCU transmits the received ID number data to an audio decoding unit; and the audio decoding unit starts to find an audio file corresponding to the ID number data in an SD (Secure Digital Memory) card, decodes the audio file, and play an analog stereo signal to a stereo output device. The tour guiding system is convenient to use, is low in cost, is convenient to maintain, and has far reading distance and quick identification speed.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a passive ultra-high frequency RFID guide system and an operation method. Background technique [0002] RFID is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various environments. It generally includes two devices, one is a radio frequency card reader device, another radio frequency ID card, which is commonly referred to as a tag card. [0003] In modern tourist attractions, large-scale exhibitions or museums and other venues, visitors need to know relevant information when viewing scenic spots or exhibits, and basically rely on tour guides to explain in one-to-many groups. Due to the lack of tour guides and cost issues, most of the audience can only take a quick look at the flowers, and the...
