Ultrahigh frequency radio frequency identification apparatus used for automatic transport

The utility model relates to the RFID (Radio Frequency Identification) technical field and concretely discloses an ultrahigh frequency (UHF) RFID apparatus used for automatic transport. The UHF RFID apparatus comprises a rack body; an upper surface of the rack body is a plane; the plane is provided with a transfer system used for transferring objects to be detected; a motor used for driving the transfer system to rotate positively and negatively is arranged under the transfer system; a case chamber fixed to the rack body is arranged above the transfer system. Rotary holders are arranged on inner sides of the case chamber and are provided with radio frequency antennas; an inner side of the case chamber is provided with a radio frequency reader-writer in connection with the radio frequency antennas; the radio frequency reader-writer and a computer interact. The case chamber is also provided with an automatic door which plays a role in shielding and is controlled by cylinders to open and close. The advantages are that the UHF RFID apparatus employs the non-contact UHF RFID technology, and avoids cofrequency signal interference in cooperation with case chamber shielding and automatic door shielding; angles of antennas are calculated according to reality, and the radio frequency antennas are carried by the rotary holders and rotate based on ideal circle centers, thereby avoiding blind angles.
