Embodiment
Below in conjunction with the accompanying drawings, embodiments herein is described.
At present, RFID technique has been widely used in jewelry Related product and periphery.It is current mainly using short in the industry
Apart from passive RFID electronic label, by the way that electronic label seal is attached in jewelry, realizes and carried out wirelessly by jewelry
The function of radio frequency identification.This jewelry with wireless radio frequency identification function may apply to many scenes, such as pass through
Ring or bracelet brush mass transit card pass through gate inhibition etc..The packaged type of electronic tag be it is diversified, typically can be by electronics
Label enters to realize encapsulation in metallic channel by being attached at metal surface or down.As an example, Figure 1A to Fig. 1 D show several
The common schematic diagram that electronic label seal is attached to ring of kind.
In order to facilitate understanding, the basic concepts of RFID technique are simply introduced below.
RFID radio frequency identifications, it is a kind of contactless automatic identification technology.It can be known automatically by radiofrequency signal
Other destination object simultaneously obtains related data, and identification work can be operated in various adverse circumstances without manual intervention.Due to RFID
Swiftly passing object can be identified, and multiple targets can be identified simultaneously, it is swift and convenient to operate, thus charged in supermarket and be
It is used widely in system, electronic toll collection (Electronic Toll Collection), public transport charge system.
RFID system comprises at least electronic tag and reader two parts.
Electronic tag, one kind can be considered as and be attached on object, the label based on RFID technique identification destination object.Typically
It can be made up of label antenna and label special chip.As the data medium of radio-frequency recognition system, each electronic tag has
Unique electronic code.After electronic tag enters magnetic field, the radiofrequency signal that identifying system is sent is received, is obtained by induced-current
Energy send out storage product information in the chips, or actively send the signal of a certain frequency, the solution in identifying system
After reading device reading information and decoding, deliver to CIS and carry out data processing.Can be according to above-mentioned communication process, by electronics
Label is divided into passive type, semi-active type, active, also referred to as passive label, semi-active semi-passive label, active label.
Reader, or read write line, it can be understood as it is a kind of to carry out radio communication with RFID, realize to RFID
The device of the read or write operation of electronic tag identifier and internal storage data.Reader can typically include sending
Device, receiver, control unit and reader antenna.RFID reader can typically be carried out by antenna and RFID
Communication.
Antenna can be considered as one kind in wireless device, for launching or receiving the part of electromagnetic wave.Antenna it is main
Effect is, will transmit the guided wave of above-the-line promotion, is transformed into the electromagnetic wave propagated in unbounded medium, or in contrast
Conversion process.Transmitting antenna and reception antenna can be divided into according to job specification, antenna often has invertibity, same to common antenna
It may be used as transmitting antenna, it is also possible to make reception antenna.
Radio-frequency recognition system is realized to mesh generally by radiofrequency signal and Space Coupling or the transmission characteristic of radar reflection
Mark the automatic identification of object.The coupling type of radiofrequency signal between reader and electronic tag is divided into inductive and electromagnetism is anti-
Coupled to scattering.Fig. 2A show transformer model, according to the law of electromagnetic induction between reader and electronic tag, passes through space
High-frequency alternating magnetic field realizes inductive, in applying in general to, the close distance radio frequency identifying system of low frequency operation.Fig. 2 B are shown
Principles of Radar model, the spatial rule between reader and electronic tag according to electromagnetic wave, the electromagnetic wave launched, is touched
To target back reflection, while target information is carried back, realize that electromagnetic backscatter couples, apply in general to high frequency, microwave operational
Long distance radio frequency identification system.
It is introduced below to REID is applied in jewelry.
When the jewelry of electronic tag and metal material is packaged together, signal function that electronic tag is sent in reader
Under, excite and induce alternating electromagnetic field, this alternating electromagnetic field is highly susceptible to the eddy current decay effect of metal but signal is strong
Degree reach decreases, in order to complete to identify, generally require closer to reader, general distance within 5 centimetres, read-write identify away from
From too small.Because metal is to the reflection and absorption to electromagnetic wave, the induced electricity magnetic wave of electronic tag can be caused to decay, shielded
Cover, disturb, and then cause recognition success rate reduction and the recognition failures of reader.
Traditional packaging technology use increase between electronic tag and metal substrate anti-metal or nonmetallic materials carry out every
Absolutely, to avoid interference of the metal swirl to the induced electricity magnetic wave of electronic tag.On the one hand, increase anti-metal material causes encapsulation to flow
Cheng Gengwei is cumbersome, and adds encapsulation process material, adds processing cost.On the other hand, jewelry is in process
In, often using last flow of the plating as outward appearance processing.Its object is to, it is ensured that the perfect processing of jewelry outward appearance,
Outward appearance processing again after electroplating is avoided simultaneously, causes surface damage or outward appearance to destroy.However, general RFID label tag encapsulation is used
Anti-metal material and RFID label tag can by plating processing high temperature and corrosion failure, if work flow is placed in plating flow
Afterwards, i.e., using the outward appearance processing process shown in Fig. 3, it will improve the encapsulation difficulty of electronic tag, while also easily damage
Bad plate surface and increase rehabilitation cost.
Traditional packaging technology also usually uses the electronic tag of larger specification and/or repeats electronic label antenna
The mode for being wrapped in ring shaped jewelry increases identification distance.However, using larger-size electronic tag, especially when width exceedes
During 3mm, designer generally requires forcibly to change the outward appearance of jewellery, to encapsulate electronic tag.This greatly affected pearl
Ring in various variability of precious Jewelry Design, particularly jewellery category.Winding ring shaped jewelry is repeated using by label antenna
Mode, although the increase of identification distance to a certain extent, can be realized, greatly affected the outward appearance of jewellery, it is difficult
To embody the originally due exquisite and appearance value of jewellery.
Therefore, the application considers reflection process of the electromagnetic wave of RFID in metal environment, can be by metal
Reflection and shielding to the electromagnetic wave of electronic tag are divided into enhancing and decay.As shown in figure 4, when reflection of the metal to electromagnetic wave is made
With caused electric field, when appropriate position is identical with the phase of original electric field, this electric field will increase to the intensity of electronic tag
By force, the reading success rate of electronic tag can be improved；Opposite, when phase and the original phase of electric field caused by reflex
When opposite, energy can be offset, and cause inductive electromagnetic wave attenuation.Based on this, the design method of electronic tag can be adjusted, can be with
The metal body of shielding or decay is produced, is improved to that the gain antenna for reading success rate can be strengthened.Shown in Fig. 5 A and Fig. 5 B respectively
To be changed to the top view of the jewellery after gain antenna and side view.Because the radiofrequency signal between electronic tag and reader is general
It can couple to be formed by inductive or electromagnetic backscatter, coupling principle produces the label of coupling referring to Fig. 2A and Fig. 2 B
Antenna need to be complete loops, and by the use of endless metal jewellery body as antenna, and technical principle disconnects the closed circuit generation of ring-type according to this
Antenna function, while the effect of annular gain antenna is caused, to strengthen the recognition success rate of RFID and reader.
