Abstract

The present invention discloses a double-band multiprotocol radio-frequency identification equipment system. Said system simultaneously adopts two frequency bands of 13.56 MHz and 433.92MHz, fully utilizes the different characteristics of near field electromagnetic coupling and for field electromagnetic back scatter of electromagnetic wave, and simultaneously said system is compatible with several protocols of ISO/IEC 18000-3, ISO/IEC 14443A and ISO/IEC 1800-7. At the same time of near distance identification of passive radio frequency label the passive radio frequency label can be used as active radio frequency label, and the identified information can be automatically transferred to the far-distance background control module. The passive radio frequency label identification distance is 0-10 cm, and the active radio frequency label identification distance is 0-500 m.

Description

Technical field: [0001] The invention relates to the technical field of radio frequency identification (RFID), in particular to the technical fields of passive radio frequency identification equipment and active radio frequency identification. Background technique: [0002] Radio Frequency Identification (RFID for short) is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. It is fast, accurate and reliable. The composition of the RFID system will vary depending on the application, but it basically consists of three parts: electronic tags, readers, and data exchange and management systems. The application of RFID can be traced back to World War II when it was used to identify friend or foe in air combat operations. With the advancement of technology, the application field of RFID is expanding day by day, and it has been involved in all aspects of people's daily life, and...
