Abstract

The present invention discloses a new type active radio frequency identification (RFID) system and its operation method. The described system includes active RFID tag, active reader and its communication protocol. Said system is worked at 2.45 GHz of ISM frequency channel, the described tag portion includes microprocessor, radio frequency receiving / sending chip, power supply management, real timeclock (RTC) and antenna. The described reader mainly includes microprocessor, radio frequency receiving and sending chip, power supply management, real-time clock (RTC), liquid crystal display, external interface module and antenna, etc. At the same time it provides RS-232 interface, and can implement communication with PC machine.

Description

Technical field: [0001] The invention relates to the technical field of radio frequency identification, in particular to a novel active radio frequency identification system and its operating method. Background technique: [0002] Radio Frequency Identification (RFID) is a kind of automatic identification technology, that is, to identify targets through non-contact two-way data communication through radio frequency. It has the characteristics of fast, accurate and reliable, and can be widely used in production and logistics. , Transportation, transportation, medical, anti-counterfeiting, tracking, equipment and asset management and other application fields that need to collect and process data. [0003] At present, a typical RFID system generally consists of RFID tags, readers, and computer systems. The spatial coupling of the radio frequency signal is realized through the coupling element between the electronic tag and the reader, and in the coupling channel, energy transm...
