Description
Technical field
The present invention relates to technical field of RFID, and in particular to a kind of dual-mode RFID tag.
Background technology
At present, what passive RFID identification technology and active RFID identification technology had developed is very ripe, and it is according to respective
Advantage each field apply it is very extensive., because it is without power supply, service life is not by using frequently for passive RFID identification technology
Numerous degree influence, thus it is widely used in the fields such as access card, mass transit card；But it has many shortcomings, such as its identification distance is near,
Multi-targets recognition ability is weak, without external interface driving force, unitary function, be only used for identification association area.Active RFID
Identification technology is widely used in the fields such as vehicle identification because its identification distance is remote, multi-targets recognition ability is strong；But its
Many shortcomings are equally existed, such as identification border is not obvious, need battery to power, and the life-span is influenceed by using frequent degree.
In very ripe today that passive RFID identification technology and active RFID identification technology develop, much field is being used
Close, both need to realize the closely identification to single target, it is also desirable to realize the long-range identification to single goal, for example logistic storage
In management, asset management the in/out storehouse stage, it is necessary to be checked one by one goods, it is desirable to distance is near, and speed is fast, now
It is relatively good using passive RFID identification technology；And checking storehouse, bring down stocks when, transport midway the stage such as check when, it is only necessary to know total
Number, approximate location is now preferable using active RFID identification technology.I.e. in some fields, it needs to realize that active RFID recognizes skill
Art and passive RFID identification technology advantage are combined, and need to realize mutually enjoying for both information.But, because passive RFID recognizes skill
The label of art does not have external interface, how to realize that the shared information resources of active RFID and passive RFID are also very thorny asking
Topic.
The content of the invention
In order to solve the above-mentioned technical problem patent of the present invention provides a kind of dual-mode RFID tag.
The present invention is achieved through the following technical solutions：
A kind of dual-mode RFID tag, including control circuit, active RFID radio frequency communications circuitry, NFC communication circuit, it is active
RFID radio frequency communications circuitries, NFC communication circuit are all connected with the control circuitry, also including being control circuit and active RFID radio frequency
Telecommunication circuit provides the power circuit of electric energy.The present invention is improved on the basis of existing technology, using bimodulus pattern, will
NFC label is combined with active electronic label technology, has both realized passive RFID identification technology and active RFID identification technology
The combination of advantage, also achieves the shared of information resources.In many application scenarios, PFID is accessed by NFC communication circuit and is marked
Sign, do not use battery, embody the advantage of passive RFID identification technology.In the case where active RFID is needed to use, by active
RFID radio frequency communications circuitries access RFID label tag, embody a concentrated reflection of the advantage of active RFID identification technology.Both have complementary advantages, with gram
The defect that both clothes are used alone.It has external interface to NFC communication circuit, is connected with control circuit by external interface, has
Source RFID radio frequency communications circuitries access the memory cell of NFC communication circuit by control circuit, realize letter in PFID labels
The mutual of breath is enjoyed.
Preferably, the NFC communication circuit is connected by spi bus with control circuit.
Further, the active RFID radio frequency communications circuitry stores data in NFC communication circuit by controlling circuit
In.Active RFID data storage is typically stored in flash or E2rom, to reach the purpose of data power down holding, and in NFC
The holding of portion's data is without power supply.Therefore active RFID shares memory space with NFC, has effectively saved cost, improves effect
Energy.For the interface channel that identical information provides active and passive access.
Patent of the present invention compared with prior art, has the following advantages and advantages：
This programme use bimodulus pattern, will NFC label combined with active electronic label technology, both realized passive
The combination of RFID identification technologies and active RFID identification technology advantage, also achieves the shared of information resources.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding the embodiment of the present invention, constitutes of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is structured flowchart of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention become more apparent, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
It is limitation of the invention.
Embodiment
A kind of dual-mode RFID tag as shown in Figure 1, including control circuit, active RFID radio frequency communications circuitry, NFC communication electricity
Road, active RFID radio frequency communications circuitry, NFC communication circuit are all connected with the control circuitry, also including being control circuit and active
RFID radio frequency communications circuitries provide the power circuit of electric energy.
NFC communication circuit is generally operational in low-frequency range, and active RFID radio frequency communications circuitry is generally operational in 2.4Ghz, and two
The frequency range of person is different.Needs know that above-mentioned frequency range only provides a conventional frequency range, and this programme scope of the claimed is not limited
In this, the purpose for providing this specific embodiment is only that and readily appreciates this programme.Using the scheme of the embodiment, in logistics storehouse
In storage management, in the in/out storehouse stage of asset management, when checking goods, communicated using NFC communication circuit；And
Checking storehouse, bring down stocks when, transport midway the stage such as check when, it is only necessary to sum is known, during approximate location, using active RFID radio frequency
Telecommunication circuit is communicated.Due to the external interface of NFC communication circuit, passive RFID identification technology and active RFID are effectively realized
The combination of identification technology, and realize that NFC communication circuit and the information of active RFID radio frequency communications circuitry are mutually enjoyed.
Specifically, NFC communication circuit is connected by spi bus with control circuit.Herein NFC communication circuit with control circuit
Between also data exchange can be carried out by I2C buses, but spi bus have speed fast, up to 10MHz, access reliable, at a high speed
Access when doing big data quantity with active MCU and interacting, it is short with the time, beneficial to the advantage of power saving.Active RFID radio communication electricity
During road stores data in NFC communication circuit by control circuit, active RFID radio frequency communications circuitry is by NFC communication circuit
As memory, and accessed by spi bus, using which, data are stored directly in NFC communication circuit, are either existed
Call active RFID radio frequency communications circuitry data or NFC communication circuit data when, avoid to the frequent of active device
Access, further reduce energy consumption.
Specifically, active RFID radio frequency communications circuitry can be realized by chip CY6936-40LFXC and its peripheral circuit, NFC
Telecommunication circuit can be realized that control circuit can be by chip STM8L152 and its peripheral circuit by chip M24SR02 and its peripheral circuit
