Description

A kind of packaging bag with RFID information loads

Technical field

The utility model relates to a kind of packaging bag, is specifically related to a kind of packaging bag and preparation of the RFID of having information loads.

Background technology

Woven bag (packaging bag) is a kind of common packing material, is generally taking plastics PP or other fiber (can be also nonwoven fabrics) as raw material, and the flat filament through extruding, being drawn into obtains after braiding.In packed and transported process, the Action of Gravity Field that woven bag is mainly subject to packing object is tension state always, because braiding adopts crisscross transmission, makes woven bag have good pull resistance and the anti-performance that pierces through, can not break easily, therefore be widely used.But common packaging bag edge aspect load information needs development.RF identification is RFID(Radio Frequency Identification) technology, claim again radio frequency identification, be a kind of communication technology, can identify specific objective and read and write related data by radio signals, and without setting up machinery between recognition system and specific objective or optics contacts.Conventional have low frequency (125k～134.2K), high frequency (13.56Mhz), superhigh frequency, technology such as microwave.Rfid interrogator also divides portable and fixed type.The basic functional principle of RFID technology is also uncomplicated: label enters electric fieldbehind region, receive the radiofrequency signal that plug-in reader sends, the energy that relies on inducing current to obtain sends out product information (the Passive Tag being stored in radio frequency chip, passive label or passive label), or initiatively sent signal (the Active Tag of a certain frequency by electronic tag, active label or active tag), after plug-in reader reading information decoding, deliver to CIS and carry out relevant data processing.A set of complete rfid system, by reader (Reader) and electronic tag (TAG microchip+antenna forms), namely so-called responser (Transponder) and three part institutes of application software system are formed, its principle of work be Reader launch a characteristic frequency radio wave energy to Transponder, in order to drive Transponder circuit, inner data are sent, now Reader just sequentially receives unscrambling data, gives application program and does corresponding processing.

Because the restriction of electronic tag ability (storage capacity, communication capacity), must take into full account feature separately at the data representation format of links, take different manifestation, so be restricted in the application of normal packet pack.Main frame can be independent of read write line and air interface protocol to the access of label in addition, that is to say that read write line and air interface protocol application programs are transparent.The application interface of RFID data protocol is based on ASN.1, and it provides a set of application program, operating system and programming language of being independent of, and is also independent of the imperative structures between tag read-write equipment and label driving.Set up at present related standards: the RF identification of ISO/IEC18000-3 information techenology-based on the management of single product-be applicable to high band 13.56MHz, physical interface, agreement and order between regulation read write line and label are added anti- collisionmethod.Can be divided into two kinds of patterns about anticollision protocol, and pattern 1 is divided into basical traditional model and two kinds of extended pattern agreements (reading agreement without termination multiple-answering machine agreement and time slot termination adaptive polling multiple-answering machine without time slot).Pattern 2 adopts the multiplexing FTDMA agreement of time-frequency, has 8 channels, is applicable to the more situation of number of labels.The RF identification of and for example ISO/IEC18000-6 information techenology-based on the management of single product-be applicable to hyper band 860～960MHz, collision-proof method is added in physical interface, agreement and order between regulation read write line and label.The interface protocol that it comprises TypeA, TypeB and tri-kinds of passive labels of TypeC, communication distance can reach 10m farthest.Although because passive type electronic tag reading capability and communication reliability are subject to larger restriction, although the cost of radio frequency chip is easy to drop to several cents, how need to be designed in the application of packaging bag the most widely.The antenna of prior art generally designs at circuit card, and upperlimit is no more than 100*100mm3, and length of arrangement wire, thickness, line interval all can affect resonance frequently, need by adjusting suitable inductance value and capacitance, to reach maximum distance.The method of prior art is not suitable for packaging bag on cost He in function.

RFID passive antenna and chip composition.Described reader is the ALR-9900 type RFID reader of Aline company.Described chip adopts the RI-UHF-STRAP-08 cake core of TI company, and in the time of 915MHz, its impedance is 83.72-j16.66 Ω.

Electronic tag is the data carrier of rfid system, electronic tag be mostly by coupling original paper (coil, micro-band antennadeng) and microchip composition parasitic element.

The high-frequency band using in rfid system is 3-30M, and information Perception distance is generally 1.5 meters, and the cost performance of system and electronic labeling device is high, for commodity anti-theft etc.

The superfrequency 300M-3G using in rfid system, information Perception distance is generally 5 meters of left and right, and more than 3 meters, cost performance and penetrating capacity are slightly poor, but data transmission fast speed is fast, and penetrating capacity is slightly poor, is generally used for warehousing management, logistic track.

At present, traditional woven bag (comprising various packaging bags) can not effectively solve that communication is reliable, transmission distance is long, with low cost, and be applicable to flexible packaging bag and adhere to, and the packaging bag with RFID information loads and preparation easy to process.
