The invention discloses a vehicle identification and positioning device based on RFID. The vehicle identification and positioning device comprises a circular phased-array antenna and an RFID reader-writer host which are electrically connected, wherein the circular phased-array antenna is used for transmitting a carrier signal in a rotating manner at a preset angular speed and preset power along the circumferential direction of the circular phased-array antenna according to a control signal of the RFID reader-writer host, receiving a reflected wave signal of a vehicle body reflected carrier signal and receiving a return signal of the vehicle-mounted RFID tag; the RFID reader-writer host is used for calculating the linear distance and the azimuth angle between the vehicle and the circular phased-array antenna according to the reflected wave signal and the return signal, and calculating the position information of the vehicle based on the linear distance and the azimuth angle. A vehicle positioning function is realized.

    本发明公开了一种基于RFID的车辆识别定位装置,包括:电连接的圆形相控阵天线和RFID读写器主机;圆形相控阵天线用于根据RFID读写器主机的控制信号沿圆形相控阵天线的周向以预设角速度和预设功率旋转发射载波信号,并接收车身反射载波信号的反射波信号以及接收车载RFID标签的返回信号;RFID读写器主机用于根据反射波信号和返回信号分别计算车辆与圆形相控阵天线之间的直线距离和方位角,并基于直线距离和方位角计算车辆的位置信息。实现车辆定位功能。
