Description

Adjustable RFID tag recognition device based on dual-mode recognition system Technical Field The utility model relates to the technical field of Internet of things equipment, in particular to an adjustable RFID tag identification device based on a dual-mode identification system. Background An RFID tag recognition apparatus is a device that performs a non-contact automatic recognition technique using radio waves. The RFID tag is communicated with an RFID tag (also called an electronic tag or a smart tag) through radio waves, so that automatic identification and data acquisition of an object are realized. RFID technology is widely used in a number of fields of logistics, retail, manufacturing, medical, transportation, etc. for tracking and managing items, personnel and assets. The traditional RFID identification device is mainly fixedly installed, is difficult to adapt to tag positions with different heights or angles, and is particularly easy to occur identification blind areas in dynamic scenes such as forklift trucks, conveyor belts and the like, and the omission ratio is high. A production line detection table for RFID identification devices is disclosed in CN205246901U, and comprises a plurality of detection positions which are arranged in a straight line or in an array, wherein each detection position comprises a bottom plate and two oppositely arranged side plates, the side plates are fixedly arranged on two opposite sides of the bottom plate, the side plates are iron plates, and at least one magnet body is fixedly arranged on one side plate. The above problems are also caused by the fact that the detection antennas are mounted above the plurality of detection positions in the production line detection table for the RFID identification device, which corresponds to the RFID read/write module, and the positions of the detection antennas are fixed. Disclosure of utility model The utility model aims to provide an adjustable RFID tag identification device based on a dual-mode identification system, which realizes the cooperative work of RFID and ultrasonic dual-mode by combining an ultrasonic ranging module and an RFID read-write module, and meets the RFID tag identification requirements of different heights and angles.
