Description
Technical field
The utility model relates to wireless technical field, relates in particular to a kind of less radio-frequency (Radio Frequency IDentification, RFID) label of directive reception.
Background technology
RF identification is RFID (Radio Frequency IDentification) technology; Claim electronic tag, radio frequency identification again; It is a kind of communication technology; Can discern specific objective and read and write related data through radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.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 made up of three parts, label (Tag): be made up of coupling element and chip, each label has unique electronic code, attached to identifying destination object on the object; Reader (Reader): read the equipment of (can also write sometimes) label information, can be designed to hand-held or fixed; Antenna (Antenna): between label and reader, transmit radiofrequency signal.
The basic functional principle of RFID technology is also uncomplicated: after label gets into magnetic field; Receive the radiofrequency 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 transponder of electronic tag (TAG) (Transponder) and three of application software systems; Its principle of work is that the radio wave energy that Reader launches a CF is given Transponder; In order to drive the Transponder circuit data of inside are seen off, 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 back scattering couplings (Backscatter Coupling); The RFID of general low frequency mostly adopts first kind of formula, and higher-frequency adopts the second way mostly.Reader according to the structure of using with technological different can be to read or read/write device, be rfid system information Control and processing enter.Reader is made up of coupling module, transceiver module, control module and interface unit usually.The general half-duplex operation mode that adopts is carried out message exchange between reader and the transponder, and reader provides energy and sequential through coupling to passive balise simultaneously.In practical application, can further pass through Ethernet (Ethernet) or WLAN (Wireless Local Area Networks, WLAN) etc. and realize management functions such as collection, processing and teletransmission object identification information.Transponder is the information carrier of rfid system, and transponder is formed parasitic element by coupling original paper (coil, microstrip antenna etc.) and microchip mostly at present.
No matter RFID is militarily, still on civilian, all is widely used.But in some special applications; For example; In medical field, apparatus wherein or vessel have special request for utilization, and its wireless signal transmitting that requires radio frequency label is to not dispersing; But can be directed, and the radio frequency label equipment of prior art can't solve this technical matters.
