Embodiment 1

[0025] figure 2 It is a schematic structural diagram of an RFID reader-writer according to an embodiment of the present invention. The RFID reader-writer 200 provided in this embodiment includes an antenna assembly 210 and a read-write component 220 . The antenna assembly 210 is connected to the read / write unit 220 via a signal connection 230 . The signal connection 230 between the antenna assembly 210 and the read / write component 220 includes a radio frequency signal connection 231 and a low frequency signal connection 232 . The signal connection 230 may specifically be implemented as a wired line connection or a specific wireless signal connection. For example, the signal connection 230 may be implemented as a cable, or as a transmission line on a printed circuit board, or other similar lines. The signal connection 230 may be a single physical line or two separate physical lines in physical implementation.

Abstract

The present invention provides an RFID reading and writing device, an antenna component thereof and a reading and writing component thereof. A position sensor is arranged in the antenna component. Through the integration of the position sensor in the antenna component, the position of an object to be measured with an RF label relative to the antenna component can be sensed and measured, thus reading and writing equipment can accurately judge whether the object with the read label is in a reading and writing range or not according to the position signal. If the measured object is in the reading and writing range, RF label information is selected, otherwise the RF label information is discarded.

Description

technical field [0001] The present invention relates to a radio frequency identification (Radio Frequency Identification, RFID) technology, in particular to a radio frequency identification reader. Background technique [0002] RFID technology, especially Ultra High Frequency (UHF) RFID technology is widely used in logistics and manufacturing fields. For most applications, the ideal situation is that the RFID reader only reports the information read from the RFID tag located directly in front of the RFID reader antenna. However, due to the multipath effect of radio wave propagation, the reading area of ​​the RFID reader is difficult to control, and RFID tags with a long distance may also be read by the RFID reader, resulting in misreading. [0003] figure 1 An existing RFID reader-writer 100 is exemplarily shown. figure 1 The shown RFID reader 100 includes an antenna assembly 110 and a read / write component 120, and the read / write component and the antenna assembly are con...
