Problems solved by technology

[0002] The traditional RFID identification device scans through one or two manually controlled antennas, which cannot cover the entire area and will cause reading dead spots; more importantly, the antenna movement must be done manually, which is very inefficient; because the antenna is fixed, the antenna The angle cannot be changed, and it will also cause some areas that cannot be covered
Therefore, the traditional gantry cannot meet the needs of related applications based on RFID technology

Abstract

The invention discloses a gantry type automatic scanning identification device based on RFID technology, which comprises a beam on the top, first columns on both sides, a second column and a bottom frame to form a gantry structure. There is a rotating platform; the horizontal beam is provided with a horizontal RFID reader antenna; the first column is provided with a first vertical RFID reader antenna, and the second column is provided with a second vertical RFID reader antenna. The invention uses a gantry to expand the coverage area of ​​the RFID reader antenna, uses a motor for automatic control, replaces the traditional manual control, and improves efficiency. The present invention uses three RFID reader-writer antennas, which can move up and down or left and right, and the antennas are fixed on the pan platform, and can be rotated spherically, thereby expanding the coverage of the reader-writer antennas. The motor controls the up and down or left and right movement of the antenna, the spherical rotation of the pan-tilt, and the rotation of the rotating platform to realize automation.

Description

technical field [0001] The invention relates to the field of automatic identification of RFID tags, in particular to a gantry type automatic scanning identification device based on RFID technology. Background technique [0002] The traditional RFID identification device scans through one or two manually controlled antennas, which cannot cover the entire area and will cause reading dead spots; more importantly, the antenna movement must be done manually, which is very inefficient; because the antenna is fixed, the antenna The angle cannot be changed, and it will also cause some areas that cannot be covered. Therefore, the traditional gantry cannot meet the requirements of related applications based on RFID technology. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a gantry type automatic scanning identification device based on RFID technology for the deficiencies of the prior art.
