The invention discloses a ultrahigh frequency RFID read-write method and ultrahigh frequency RFID read-write device. The method comprises the following steps of: forming a substrate; wherein the ultrahigh frequency RFID antenna performs composite motion, the composite motion comprises linear reciprocating motion based on the X-axis forward direction and linear motion based on the Z-axis, the initial position of the ultrahigh frequency RFID antenna is located at a point O (0, 0, 0) where the three-dimensional orthogonal X-axis, Y-axis and Z-axis intersect, and the linear motion is one-way linear motion or linear reciprocating motion; when the ultrahigh frequency RFID antenna moves to an X-axis coordinate (X0, 0, 0), returning to an initial position or a nearby position; and when the ultrahigh frequency RFID antenna returns to the initial position or the position near the initial position, the composite motion is repeated to form a circulating reciprocating motion. Through X-axis forwardlinear reciprocating motion of the ultrahigh-frequency RFID antenna and composite motion based on Z-axis linear motion, the position of the ultrahigh-frequency RFID antenna is changed, so that signalblocking and interference of obstacles are effectively avoided, the reading range of the ultrahigh-frequency RFID antenna is enlarged, and the reading success rate of the ultrahigh-frequency RFID antenna is increased.
Description
technical field [0001] The invention relates to the technical field of communication equipment, in particular to an ultra-high frequency RFID reading and writing method and an ultra-high frequency RFID reading and writing device applying the ultra-high frequency RFID reading and writing method. Background technique [0002] At present, RFID technology is widely used in the storage, inventory and management of materials to achieve intelligent management. It does not require contact identification, can penetrate various media and read, and the reading speed is fast. The UHF RFID antenna is installed on the electronic device to receive or transmit wireless signals. Since the propagation of wireless information is interfered by the external environment, it is prone to distortion and distortion. The UHF RFID antenna is often manually adjusted to reduce interference. The operation is troublesome, and it is easy to be interfered by the external environment again, which reduces the ...
