Background technique
RFID is the abbreviation of Radio Frequency Identification, and promptly RF identification is commonly called as radio-frequency (RF) tag, or electronic tag.
The RFID RF identification is a kind of contactless automatic identification technology, and it is by the automatic recognition objective object of radio signal and obtain related data, and identification work need not manual intervention, can work in various rugged environment.The RFID technology can be discerned high-speed moving object and can discern a plurality of labels simultaneously, and is swift and convenient to operate.
RFID is a kind of simple wireless system, has only two basic devices, and this system is used for control, detection and tracking object.System is made up of a challenger (or reader) and a lot of XPNDR Transponder (or label).
The basic functional principle of RFID technology is also uncomplicated: after label enters magnetic field, receive the radio signal that plug-in reader sends, rely on the energy that induction current obtained to send out product information (the Passive Tag that is stored in the chip, passive label or passive label), perhaps initiatively send the signal (Active Tag, active label or active tag) of a certain frequency; After plug-in reader reads information and decoding, deliver to CIS and carry out the relevant data processing.
The complete rfid system of one cover, partly form by reader (Reader) and just so-called XPNDR Transponder of electronic tag (TAG) (Transponder) and three of application software systems, its working principle is that Reader launches the radio wave energy of a characteristic frequency to Transponder, in order to drive the Transponder circuit data of inside are sent, this moment, Reader just received unscrambling data in regular turn, gave application program and did corresponding processing.
Can be divided into haply with communication between rfid card sheet reader and the electronic tag and energy-sensitive mode, two kinds of induction coupling (Inductive Coupling) and backscattering couplings (Backscatter Coupling), the RFID of general low frequency mostly adopts first kind of formula, and higher-frequency adopts the second way mostly.
Reader is different with technology according to the structure of using can be to read or read/write device, is control of rfid system information and processing center.Reader is made up of coupling module, send receive module, control module and interface unit usually.The general half-duplex operation mode that adopts is carried out information exchange between reader and the XPNDR Transponder, and reader provides energy and sequential by coupling to passive balise simultaneously.In actual applications, can be further by the management functions such as collection, processing and teletransmission of realizations such as Ethernet or WLAN to object identification information.XPNDR Transponder is the information carrier of rfid system, and XPNDR Transponder is formed parasitic element by coupling original paper (coil, microstrip antenna etc.) and microchip mostly at present.
Satisfy multiple standards such as international ISO15693, ISO18000-6B, EPC G2, the label that adopts different antenna designs and potting material to can be made into various ways is as vehicle label, tray label, logistics label, metal label, book labels, liquid label, personnel gate inhibition's label, admission ticket label, luggage tag etc.The client can select or customize corresponding electronic label as required.
RFID ultra-high frequency (UHF) label is because of electromagnetic backscatter (Backscatter) characteristics, relatively more responsive to metal (Metal) and liquid environment such as (Liquid), can cause the passive label (Passivetag) of this frequency of okperation to be difficult under object with metal surface or liquid environment, carry out work, but this type of problem is along with the development of technology is solved fully, for example, Han Shuo (SONTEC) label company promptly develops and can carry out the intact passive label product that reads application under metal or liquid environment, disposes RFID with convenient under above-mentioned environment or application scenarios.
As an example, China is publication application CN200710008336, and a kind of RFID label manufacture method and supporting RFID label are provided.Similar techniques has much at present.
