Support table radio frequency identification read-write device

Abstract

The invention relates to a support table radio frequency identification read-write device, comprising a read-write device carrying main body and a radio frequency label read-write platform; a radio frequency identification antenna is arranged in the read-write device carrying main body; the radio frequency label read-write platform is positioned above the read-write device carrying main body and is used for placing an electronic label; a limiting support table is arranged at the upper surface of the radio frequency label read-write platform; when being moved, the electronic label is limited by the limiting support table. According to the support table radio frequency identification read-write device adopting such a structure, the mistuning of response frequency caused by the direct contact between the electronic label and the surface of the read-write device is reduced; the limiting platform can be arranged according to the size of the electronic label; the positions of the radio frequency identification antenna and the limiting support table can be adjusted, so the electronic label works in an optimized near field radiation area; the structural parameters of the limiting platform are set according to the size of the electronic label, and meanwhile, the projection area of the electronic label at the reader-writer device antenna is maximum; the electronic label can be conveniently fast taken down due to an easy-to-take support part.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to the technical field of radio frequency identification reader-writers, in particular to a pallet type radio frequency identification read-write device. Background technique [0002] Radio frequency identification technology uses radio frequency to carry out non-contact two-way data communication to realize non-contact automatic identification of marked objects. This technology overcomes the limitation of line of sight effect, completes information input and processing without intervention, is anti-fouling, and can be processed in batches. , automation, and modern technical features. According to the working frequency, radio frequency identification equipment can be divided into low frequency, high frequency), ultra high frequency and microwave equipment; according to the power supply method, it can be divided into active equipment and passive equipment. The...

Problems solved by technology

[0004] The antenna design of the radio frequency identification reader needs to obtain high gain in the working frequency band to complete the application requirements of reliable identification, while the response frequency band of the electronic tag antenna is very sensitive to the medium in direct contact, and the problem that the electronic tag cannot be recognized when it is placed on the surface of some objects often occurs

For RFID readers, the electronic tag will directly contact the surface of the RFID reader, which will cause the response frequency band of the electronic tag to shift, and the frequency band of the RF signal emitted by the reader is designed according to the original response frequency band. It cannot follow the frequency offset of the electronic tag, so it will be difficult for the reader to read and write the electronic tag
