Description
Technical field
The utility model relates to field of radio frequency identification, tells about more specifically to relate to one and utilize the magnetic-coupled mode of high-frequency electrical to provide energy for ultrahigh-frequency tag, realizes more stable, and versatility is stronger, apart from farther RFID dual-frequency label.
Background technology
RFID technique development rapidly, application is more and more wider, high-frequency label saves energy than ultrahigh-frequency tag, penetrate nonmetal object muscle power strong, ultrahigh frequency reach is wide, transmits data speed fast, but they compare power consumption, penetration power is more weak, and from signal disturbing aspect, ultrahigh frequency more depends on the communication environment between reader and label than High frequency RFID systems.The near field of high frequency technique inductively decreases potential air interference, and high frequency technique is had extremely strong " immunity " neighbourhood noise and electromagnetic interference (EMI).In some practice (such as commodity particular surroundings), need the more stable of RFID label tag tool, versatility is stronger, apart from farther, by using described RFID label tag, can significantly improve workability, applicability.
The RFID label tag that current reality uses is different according to the mode of emitting radio frequency signal, is divided into active and passive type two kinds.Active tag is initiatively to read write line emitting radio frequency signal, usual internal battery is powered, be otherwise known as active label, the working power of label is supplied by internal cell completely, the energy supply of tag battery simultaneously is also partly converted to label and the radio-frequency (RF) energy needed for reader communication, return message transmit signal power is large, and generally have reading distance far away, cost is higher compared with passive label; Passive label is charged pool not, is also called passive label, and time outside the read range of reader, label is in passive states, and time within the read range of reader, label extracts the power supply needed for its work from the radio-frequency (RF) energy that reader sends.Return message transmit signal power is little, and write distance then more closer, confronting active label cost is lower, long service life, and volume is little.
The coupling type of the radiofrequency signal between reader and label has two kinds: 1, inductive coupling, the transformer model taked, and realizes coupling by spatial high-frequency alternating magnetic field.In being generally applicable to, the close distance radio frequency recognition system of low frequency operation, identify that yesterday, distance was less than 1m, be mainly used in the application of short distance, low cost.2, electromagnetic backscatter, what take is Principles of Radar models, and the electromagnetic wave launched is encountered target back reflection, carried back target information simultaneously, is based on electromagnetic spatial rule.Decipherment distance is greater than 1m, is mainly used in the occasion needing longer reading/writing distance and high read or write speed.
Utility model content
The purpose of this utility model is to provide a kind of magnetic-coupled mode of high-frequency electrical that utilizes and provides the dual-frequency label of energy for ultrahigh-frequency tag.For this reason, the utility model is by the following technical solutions:
Utilize the magnetic-coupled mode of high-frequency electrical to provide a dual-frequency label for energy for ultrahigh-frequency tag, it is characterized in that described dual-frequency label comprises: HFS circuit structure, UHF part circuit structure; UHF part circuit structure comprises the chip and ultra-high frequency antenna with memory function, the information being in the tag storage of state of activation is initiatively sent, is received, realize exchanges data by ultrahigh frequency readers; HFS circuit structure has the high-frequency radio frequency tag of receiving coil and matching capacitance formation, and HFS circuit structure also has rectification, filtering and mu balanced circuit; Described high-frequency radio frequency tag realizes the energy exchange between label and reader antenna by the mode of high frequency reader antenna inductive coupling; High-frequency radio frequency tag connects described rectification, filtering and mu balanced circuit, described rectification, filtering and mu balanced circuit are connected in the power pins of described chip, ultra-high frequency antenna is connected on the functional pin of described chip, the induced voltage produced by HFS circuit structure is described chip power supply, UHF part is activated, and label obtains work capacity.
Dual-frequency label provided by the utility model obtains work capacity by the inductive coupling mode of high-frequency circuit from the radiating near field of reader pickup coil, receiving coil configures electric capacity to form 8.2MHz frequency radio-frequency (RF) tag, larger power transfer can be obtained under this frequency.Be now that label information is sent on reader by carrier by ultra-high frequency band (860MHz-960MHz) circuit.Idiographic flow is that HFS utilizes coil electromagnetism coupling principle, and after adopting coil to be connected with electric capacity, the principle of resonance forms induction current (voltage).Rectifying part, filtering voltage regulation part and direct output is added in circuit, ultrahigh frequency circuit is made to obtain enough cut-in voltages by the mode that ultrahigh frequency matching chip connects required galvanic current pressure, label obtains work capacity, active label (active tag) is become from the formal transformation of passive label, the rf wave that the label of the duty that has the initiative and reader antenna are launched interacts, have stable, recognition distance far away, completes exchanges data in real time.The coverage that only need enter corresponding high band antenna signal source during use, without the need to carrying out communication setting and debugging, just can normally work.
Reader antenna coordinates with " active " of the present utility model active label, active label is in a particular application compared with passive label, the decipherment distance stablizing superpower signal and overlength has very large advantage, even if paste metal or containing the environment of moisture content or object, the feature that communication distance also can not decline, meets the requirement that user is longer to decipherment distance.Meanwhile, when being used in batch identification, decrease identification error.
HFS of the present utility model and UHF part also can separate independent use.HFS utilizes the resonance of the principle of electromagnetic coupled and reader antenna wire loop to make to obtain work capacity, can be used alone to use as passive HF label in high-frequency band (8.2MHz), is mainly used in gate inhibition, the field such as antitheft.UHF part utilizes electromagnetic backscatter principle, when in effective read range that label enters reader, label is read, information is sent to reader by the mode of backscattered modulation, can be used alone ultra-high frequency band (860MHz-960MHz) as passive label use, mainly apply the fields such as storage, logistics, parking management.
High-frequency label saves energy than ultrahigh-frequency tag, penetrate nonmetal object muscle power strong, ultrahigh frequency reach is wide, transmission data speed is fast, but they compare power consumption, penetration power is more weak, and from signal disturbing aspect, ultrahigh frequency more depends on the communication environment between reader and label than High frequency RFID systems.The near field of high frequency technique inductively decreases potential air interference, high frequency technique is had extremely strong " immunity " neighbourhood noise and electromagnetic interference (EMI), the utility model combines cleverly by utilizing in passive RFID technology structure, a kind of brand-new double-frequency radio-frequency identification tag formed, its advantage be information on this structure label can automatically by remote wireless transmission to backstage, be specially adapted to need remote occasion.Solve passive radio-frequency identification labeledly cannot to identify at a distance, the difficult problem of remote information acquisition, also solve the problems such as the power supply that ultrahigh-frequency tag is as easy as rolling off a logly disturbed, passive label changes into active label, the field that article, vehicle, metal etc. are different can be widely used in.
