A nail that realizes the function of radio frequency tags

technical field

The invention belongs to the field of electronic technology.

Background technique

RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification, commonly known as radio frequency tags, or electronic tags.

RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient.

RFID is a simple wireless system with only two basic components, which is used to control, detect and track objects. The system consists of an interrogator (or reader) and many transponders (or tags).

The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal sent by the reader, and sends out the product information stored in the chip by virtue of the energy obtained by the induced current (Passive Tag, passive tag or passive tag) , or actively send a signal of a certain frequency (Active Tag, active tag or active tag); after the reader reads and decodes the information, it sends it to the central information system for relevant data processing.

A complete RFID system is composed of three parts: the reader (Reader), the electronic tag (TAG), the so-called transponder (Transponder) and the application software system. Its working principle is that the Reader emits a specific frequency The radio wave energy is given to the Transponder to drive the Transponder circuit to send out the internal data. At this time, the Reader receives and interprets the data in sequence and sends them to the application program for corresponding processing.

From the perspective of communication and energy sensing between RFID card readers and electronic tags, it can be roughly divided into two types: Inductive Coupling and Backscatter Coupling. Generally, low-frequency RFID mostly uses the first type. mode, while the second mode is mostly used for higher frequencies.

The reader can be a reading or reading/writing device according to the structure and technology used, and it is the information control and processing center of the RFID system. The reader is usually composed of a coupling module, a transceiver module, a control module and an interface unit. The half-duplex communication mode is generally used for information exchange between the reader and the transponder, and the reader provides energy and timing to the passive transponder through coupling. In practical applications, management functions such as collection, processing and remote transmission of object identification information can be further realized through Ethernet or WLAN. The transponder is the information carrier of the RFID system. At present, most transponders are passive units composed of coupling elements (coils, microstrip antennas, etc.) and microchips.

Meet international ISO15693, ISO18000-6B, EPC G2 and other standards, use different antenna designs and packaging materials to make various forms of labels, such as vehicle labels, pallet labels, logistics labels, metal labels, book labels, liquid Tags, personnel access tags, ticket tags, luggage tags, etc. Customers can choose or customize corresponding electronic tags according to their needs.

RFID ultra-high frequency (UHF) tags are sensitive to environments such as metal (Metal) and liquid (Liquid) due to the characteristics of electromagnetic backscatter (Backscatter), which can make it difficult for passive tags (Passivetag) with this working frequency to have metal surfaces However, such problems have been completely solved with the development of technology. For example, Hanshuo (SONTEC) label company has developed a passive label that can be read well in metal or liquid environment. Products to facilitate the deployment of RFID in the above-mentioned environments or application scenarios.

As an example, Chinese published patent application CN200710008336 provides a method for manufacturing an RFID tag and a matching RFID tag. There are many similar technologies at present.
