A kind of nail realizing radio-frequency tag function
Technical field
The invention belongs to electronic technology field.
Background technique
RFID is the abbreviation of Radio Frequency Identification, i.e. RF identification, is commonly called as radio-frequency (RF) tag, or electronic tag.
RFID RF identification is a kind of contactless automatic identification technology, and it automatically identifies destination object by radio signal and obtains related data, and the work of identification need not manual intervention, can work in various rugged environment.RFID technique identifiable design high-speed moving object also can identify multiple label simultaneously, swift and convenient to operate.
RFID is a kind of simple wireless system, and only have two basic devices, 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 technique is also uncomplicated: after label enters magnetic field, receive the radio signal that plug-in reader sends, the energy obtained by means of induction current sends out storage product information in the chips (Passive Tag, passive label or passive label), or initiatively send the signal (Active Tag, active label or active tag) of a certain frequency; Plug-in reader reads information and after decoding, delivers to CIS and carry out relevant data process.
The rfid system of complete set, by reader (Reader), namely so-called XPNDR Transponder (Transponder) and application software system three part formed with electronic tag (TAG), its working principle is that Reader launches the radio wave energy of a characteristic frequency to Transponder, in order to drive Transponder circuit, the data of inside are sent, now Reader just received in sequence unscrambling data, gives application program and does corresponding process.
Can be divided into haply with the communication between rfid card sheet reader and electronic tag and energy-sensitive mode, induction coupling (Inductive Coupling) and backscattering coupling (Backscatter Coupling) two kinds, the RFID of general low frequency mostly adopts the first formula, and higher-frequency adopts the second way mostly.
Reader is different with technology according to the structure used can be read or read/write device, is that rfid system information controls and processing center.Reader is made up of coupling module, send receive module, control module and interface unit usually.Between reader and XPNDR Transponder, the general half-duplex operation mode that adopts carries out information exchange, and reader provides energy and sequential by coupling to passive balise simultaneously.In actual applications, the management functions such as collection to object identification information, process and teletransmission can be realized further by Ethernet or WLAN etc.XPNDR Transponder is the information carrier of rfid system, and current XPNDR Transponder forms parasitic element by coupling element (coil, microstrip antenna etc.) and microchip mostly.
Meet the multiple standards such as international ISO15693, ISO18000-6B, EPC G2, different Antenna Designs and potting material is adopted to can be made into the label of various ways, as vehicle label, pallet tags, logistic label, metal label, book labels, liquid label, personnel gate inhibition's label, admission ticket label, luggage tag etc.Client can select or customize corresponding electronic tag as required.
RFIDnt ultra-high frequency (UHF) label is because of electromagnetic backscatter (Backscatter) feature, more responsive to environment such as metal (Metal) and liquid (Liquid), the passive label (Passivetag) of this frequency of okperation can be caused to be difficult to carry out work under the object with metal surface or liquid environment, but problems is solved completely along with the development of technology, such as, namely Han Shuo (SONTEC) label company develops and can carry out the intact passive label product reading application under metal or liquid environment, under above-mentioned environment or application scenarios, RFID is disposed to facilitate.
As an example, China is publication application CN200710008336, provides a kind of RFID label tag manufacture method and supporting RFID label tag.Similar technology has much at present.
Summary of the invention
The object of this invention is to provide a kind of nail realizing radio-frequency tag function, in order to provide a kind of nail that can realize RFI D function.

Further, described a kind of nail realizing radio-frequency tag function, also has following technical characteristics:
Described nail chamber, its cavity structure is set to cylindrical cavity.
Aforesaid support plate obturator adopts nonmetallic material support plate obturator.
Correspond to aforesaid nail cavity configuration, chamber wall is provided with void region.
The described head of a nail is the metal cap-like structure fixed with upper end, aforesaid nail chamber oral area.
Described support plate obturator is the material allowing electromagnetic wave conducting, adopts one in plastic materials, rubber material, lamination coating or stupalith to realize.
Described nail chamber is peripheral, is provided with the guard ring of the annular be enclosed within nail chamber.
Correspond to aforesaid guard ring, be adopted as one in plastic materials guard ring, rubber material guard ring or stupalith guard ring.
The invention has the advantages that:
Utilize this nail that can realize RFID function of the present invention, before user is to target object identification, the electronic tag being provided with specific coding can be injected on target object to be identified, or it is inner to inject Loaded goods to be identified.In magnetic field range, the RFID firmware being arranged at internal system can send radio signal, and user carries out contactless automatic identification to it by using reader and obtains related data.
A nail for RFID function can be realized like this, be arranged at target object inside, the links such as statistics after which, carrying, storage can carry out identification record to it.Like this, user can identify object in the presence of a harsh environment, and adds up object.Thus reduce people to target object manage loaded down with trivial details.Utilize this recognition technology, facilitate user to the management of logistics.
