The utility model discloses a
chip RFID (
radio frequency identification) device, which relates to the technical field of
radio frequency identification, solves the problem that long-distance
radio frequency identification is not accurate enough, and comprises a
transmitter, an antenna, a reader-writer, a hardware anti-
jitter device, an RFID
chip, a controller and a power supply device. The
transmitter generates stable radio frequency signals through a
voltage oscillation circuit of the radio frequency generator, the antenna achieves long-distance transmission of the radio frequency signals through the electronic
tag antenna and the reader antenna, and the reader-writer achieves accurate reading of RFID tag data in
wireless signals through a built-in radio frequency front-end
chip, a DSP
digital signal processing chip and a hardware anti-
jitter device. The RFID identification chip accurately identifies a target object through the
radio frequency front end receiver and the arithmetic logic decoder, the controller controls the chip RFID
radio frequency identification device to operate orderly through the PLC control chip, stable radio frequency signals are provided, and remote chip RFID
radio frequency identification is greatly improved.
