Description

Microwave radio frequency identification reader-writer

Technical Field

The utility model relates to a reading and writing field specifically is a microwave radio frequency identification read write line.

Background

The microwave radio frequency identification (UHF RFID) technology is the most advanced international fourth-generation automatic identification technology and has the characteristics of long identification distance, high identification accuracy, high identification speed, strong anti-interference capability, long service life, capability of penetrating through non-metallic materials, wide application range and the like. The system is a brand new management means which is provided for automatically collecting characteristic data of objects such as attributes, states, numbers and the like for realizing digitization and informatization, and is widely applied to various management and identification systems such as vehicle management, personnel access management, logistics storage management, book management and the like.

The popularization of the internet of things enables more and more enterprises to realize the benefits brought by the RFID technology in the management process, the demand for the RFID technology is more and more definite, and the application of the RFID technology is more and more.

The communication between the UHF RFID reader-writer and the electronic tag is completed by adopting an electromagnetic backscattering coupling mode. When an object provided with the electronic tag approaches the reader-writer, the reader-writer is controlled to send out a microwave query signal, and after the electronic tag arranged on the surface of the object receives the query signal of the reader-writer, the signal and data information in the tag are synthesized into a whole and reflected to the electronic tag reading device. The reflected microwave synthesized signal carries the data information of the electronic tag. After the reader-writer receives the microwave synthesis signal reflected by the electronic tag, the information such as the identification code stored in the electronic tag can be separated and read out after the microwave synthesis signal is processed by a microprocessor in the reader-writer.

UHF RFID technology has become increasingly widely used, and has different requirements for the RFID standard of a reader/writer according to the requirements of different application fields and actual environments. The read-write machine interface that is commonly used at present is all more single, and coverage is less, and the modularization degree is relatively poor, and the machine volume is too huge again, hardly is fit for the application of multiple occasion. Therefore, the design with multiple selectable interfaces can be effectively suitable for different applications of various occasions, and the application requirements of different scenes are met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a microwave radio frequency identification read write line to solve the problem that proposes among the above-mentioned background art.
