A kind of RFID of orientable identification
Technical field
The present invention relates to technical field of RFID, particularly relates to a kind of RFID of orientable identification.
Background technology
Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, it is A kind of communication technology, specific objective can be identified by radio signals and read and write related data, without identifying system with it is specific Mechanical or optical contact is established between target.The signal of radio is the electromagnetic field by being tuned into radio frequency, data from It is attached on the label on article and sends out, is recognized with automatic with following the trail of the article.Some labels are in identification from identifier Energy is can be obtained by the electromagnetic field sent, and does not need battery；Also there is label to possess power supply in itself, and can actively send Radio wave (electromagnetic field for being tuned into radio frequency).Label contains the information of Electronic saving, can be identified within several meters. Unlike bar code, RF tag need not be within identifier sight, can also be embedded in and be tracked within object. RFID reader also divide movable type and it is fixed, RFID technique application at present is very wide.
RFID location system common in the art generally comprises positioner and reader two parts.Its positioner Generally comprise RFID label tag, LED and wireless communication module.RFID label tag is used for marking articles object, and LED is used for RFID label tag pair As identifying laggard line flicker prompting, wireless communication module carries out data message using hardware modules such as Zigbee, nFR24l01 Transmission.And reader includes card reader and wireless communication module.Card reader is used to read FRID label information, wireless communication module The transmission of data message is carried out using hardware modules such as Zigbee, nFR24l01.Itself the disadvantage is that, due to comprising wireless module and The visualization devices such as LED, power consumption is more, changes the workload that battery not only increases attendant, also improves wireless electron The hardware use cost of label.
Also, the advantages such as although RFID has that recognition speed is fast, quantity is more, in some applications, when same When there is branched RFID, any branch label when effectively can not distinguish specific, so needing solve RFID Orientation identification problem, can need orient identification application in fast positioning and identification label.
The content of the invention
The present invention proposes a kind of RFID of orientable identification, simple in construction suitable for industries such as household electrical appliances logistics, Solve in visual range, in the environment of more RFIDs, realize the problem of orientation of RFID label tag identifies, meet household electrical appliances The read-write of tag recognition and information under the scene of logistics network part, so as to realize the reading and identification of mark object information.
The technical proposal of the invention is realized in this way：
A kind of RFID of orientable identification, its structure include：

Photosensitive resistance change element be to the light-sensitive device of specified wavelength photaesthesia, when with the light irradiation of the wavelength, photosensor The resistance of part can change；
Antenna is used for coupled external electromagnetic wave energy, activates RFID chip.
Preferably, respectively one photosensitive resistance change element of connection, the photosensitive resistance change element connect respectively for the RFID chip both sides Antenna.
A kind of RFID of orientable identification, its structure include：
RFID chip and photosensitive variable resistance antenna；
There is memory block inside the RFID chip, for storage information and realize the read-write of RFID；
The photosensitive variable resistance antenna is made by photosensitive varistor material, to the photaesthesia of specified wavelength, when the light with the wavelength During irradiation, the resistance of antenna can change；
Also, the photosensitive variable resistance antenna can coupled external electromagnetic wave energy, activate RFID chip.
Preferably, the RFID chip both sides connect a photosensitive variable resistance antenna respectively.
Both the above RFID launches the illumination of specified wavelength using 900M RFID devices and specified wave producer Photosensitive resistance change element/antenna is penetrated to be identified.
When needing to identify RFID, specified ripple is used while using 900M RFID devices identification label The long light irradiation electronic tag, photosensitive resistance change element/antenna of the label are irradiated by light, and its resistance reduces, while day Line couples 900M electromagnetic wave energies, so as to be emitted after the modulates information that activates RFID chip and stored, 900M RFID Equipment identifies relevant information after receiving, and reaches the purpose that orientation identifies the RFID.
In summary, RFID of the invention, by using photovaristor part, RFID electronics is efficiently solved The problem of label orientation identification, in the application for needing to orient identification can fast positioning and identification label, and its is simple in construction, It is easy to spread.
