Described EPC part 200 also comprises base plate for packaging 230, and described base plate for packaging 230 comprises two-layer, from inside to outside as inner encapsulated layer 231 and outer enclosure layer 232.
Further, described logic module 221 is the EPC stereotyped command.
EPC part 200, its basic composition comprises: label chip 220, label antenna 210 and base plate for packaging 230; Wherein label chip 220 is core cells of label, and chip itself is a SOC (system on a chip), and System ON Chip SOC, label chip 220 are carriers of EPC standard and information storage; Label antenna 210 is coupled outside unit of EPC part 200, and label antenna 210 constitutes EPC label and the reader 100 aerial bases that are coupled with reader antenna 110; Base plate for packaging 230 is bases of EPC part 200 physical appearances, also is the basis of adhering to of EPC label chip 220 and antenna; The encapsulation of EPC label can be divided into two levels, and level is the combination between EPC label chip 220 and the EPC label antenna 210, is also referred to as inner encapsulated layer 231; Another level is the outer enclosure layer 232 of EPC part 200, is also referred to as packing.
EPC, Electronic Product Code is a kind of new product coding mode, can identify concrete each product;Each label comprises unique electronic product code EPC, like this can be to specific product in the enterprising line trace of supply chain.
By EPC part 200 identification targets, obtain all data relevant with target, finally set up the supply network that the user drives.
And the frequency of operation of EPC part 200 is important parameters of label antenna 210, and based on coordination in many ways, the frequency of operation of basic Consensus EPC part 200 is at present:
2. low-frequency range adopts the 13.56MHz of HF frequency range;
2. high band adopts the 860---960MHz of uhf band;
3. high band adopts the application space of the 2.4GHz of S frequency range.
Reader 100 mainly is made up of high frequency interface and two basic modules of control module.
The high frequency interface comprises transmitter and receiver, and its function comprises: produce high-frequency emission power to start radio-frequency card and energy is provided; Modulate transmitting, be used for sending data to radio-frequency card; Receive also demodulation from the high-frequency signal of radio-frequency card.
The function of control module comprises: communicate with application systems software, and carry out the order that application systems software is sent; The communication process of control and radio-frequency card, main one from principle; The encoding and decoding of signal; Some special systems are carried out anti-collision algorithm in addition, radio-frequency card and 100 data that will transmit of reader are encrypted and decipher, and carry out the additional functions such as authentication that radio-frequency card and reader 100 are asked.
Label antenna 210 refers to follow the RFID label of the rule of EPC part 200, and same reader 100 refers to follow the radio-frequency identification reader 100 of the rule of EPC part 200; The function of reader 100 can be summed up as following 3 points:
1. the information of initialization label chip 220.The essential information that label chip 220 comprises is-64,96 or 256 s' binary code, and according to the EPC coding rule, the EPC code is divided into: " field ", " EPC supvr ", " object classification " and " sequence number " four territories; The initialization of label chip 220 namely is the concrete operations regulation according to the EPC coding, writes the EPC code in each label chip 220.It is complete 0 that the information of the label chip 220 of un-initialized can be thought, each label is just the same.The physical location of information storage is in the chip-stored district in the label chip 220, thereby initial work also can directly be injected EPC label chip 220 in the later stage test that EPC label chip 220 is produced.
2. the information of reading tag chip 220.The information of reading tag chip 220 is main tasks that reader 100 is taken in the real world applications.Read EPC code information in EPC part 200 labels that each Individual Items attaches by reader 100 at different collocation points, realize that the EPC Internet of Things is to the collection of Individual Items identification information.On this basis, can realize accurate control and management to the logistics information inquiry service.The collection of label chip 220 is the most key in EPC Internet of Things sport technique segments.
3. make label chip 220 disablers.Because the EPE concept is positioned to give a globally unique code for any commodity.After commodity were sold, the entitlement of commodity had been transferred in consumer's hand, and consumer's its commodity of purchasing of requirement of having the right no longer keep being continued the power of following the tracks of down as the flow of commodity." destroying (Kill) " order ad hoc in the EPC label namely need and be set at this.Because the basic fixed position of EPC part 200 passive design has only by reader 100 and sends " destroying (Kill) " order to it, could make the EPC label function lose efficacy.The EPC label of disabler will no longer can be read the EPC code by reader 100.
Three functions that EPC label reader 100 has also can be realized by the equipment of three different titles respectively.According to the demands of applications situation, reader 100 can make antenna and reader main frame split type or integral type.
Antenna can be divided into short-wave antenna, ultrashort wave antenna, microwave antenna etc. by working frequency range; Can be divided into omnidirectional antenna, directional antenna etc. by directivity; Can be divided into wire antenna, planar antenna etc. by profile.Antenna generally is built in label and the reader 100, and label antenna 210 and reader antenna 110 are also born the effect of received energy and emitted energy respectively.
A kind of novel radio radio-frequency recognition system that the utility model provides arranges on-chip system chip by EPC part 200, can carry out batch scanning, overcomes the disadvantage of conventional labels greatly; Can by EPC part 200 identification targets, obtain all data relevant with target, for the supply network of further setting up user's driving provides the basis to specific product in the enterprising line trace of supply chain.
Certainly; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art should make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
