POSITION-DETECTING RADIO FREQUENCY IDENTIFICATION DEVICE AND METHOD THEREOF

摘要

Provided is a position-detecting radio frequency identification (RFID) device, including a pair of radio frequency antennas transmitting and receiving a radio frequency signal, a RFID chip electrically connected to and corresponding to the pair of first radio frequency antennas, storing a signal, and stimulating the pair of radio frequency antennas into transmitting and receiving the signal, a pair of electronic switches provided between the pair of radio frequency antennas and the RFID chip, and a switch control device controlling the pair of electronic switches. Moreover, if the pair of electronic switches is in the on state, the pair of radio frequency antennas and the RFID chip are electrically connected, and if the pair of electronic switches is in the off state, the pair of radio frequency antennas and the RFID chip are electrically disconnected. Further, the present invention also provides a position-detecting RFID method.

主权项

1. A position-detecting radio frequency identification (RFID) device, comprising:
a pair of first radio frequency antennas transmitting and receiving a radio frequency signal; a first RFID chip electrically connected to and corresponding to the pair of first radio frequency antennas, storing a signal containing position information, and transmitting the signal through the pair of first radio frequency antennas; a pair of first electronic switches electrically connected to the pair of first radio frequency antennas and the first RFID chip in series, wherein one of the pair of first electronic switches is provided between one of the pair of first radio frequency antennas and the first RFID chip, another one of the pair of first radio frequency antennas is provided between another one of the pair of first radio frequency antennas and the first RFID chip; and a switch control device controlling the pair of first electronic switches, wherein if the pair of first electronic switches are in the on state, the pair of first radio frequency antennas and the first RFID chip are electrically connected, and if the pair of first electronic switches are in the off state, the pair of first radio frequency antennas and the first RFID chip are electrically disconnected.
