Background technology

RFID is the abbreviation of Radio Frequency Identification, and promptly radio-frequency (RF) identification is commonly called as electronic tag.The RFID radio-frequency (RF) identification is a kind of contactless automatic identification technology, and it is by the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention, can work in various rugged surroundings.The most basic rfid system is made up of three parts: label (Tag): be made up of coupling element and chip, each label has unique electronic code, attached to identifying destination object on the object; Plug-in reader (Reader): read the equipment of (can also write sometimes) label information, can be designed to hand-held or fixed; Antenna (Antenna): between label and plug-in reader, transmit radiofrequency signal.The basic functional principle of RFID technology: after label enters magnetic field, receive the radiofrequency signal that plug-in reader sends, rely on the energy that induction current obtained to send out product information (the Passive Tag that is stored in the chip, passive label or passive label), perhaps initiatively send the signal (Active Tag, active label or active tag) of a certain frequency; After plug-in reader reads information and decoding, deliver to CIS and carry out the relevant data processing.The RFID technology can be discerned high-speed moving object and can discern a plurality of labels simultaneously, and is swift and convenient to operate.The far Distance RFID REID is applicable to intelligent transportation (ITS), mine, logistics, gate inhibition, work attendance, production process at present, and the automatic management of the people of all conglomeraties such as army, hospital, frontier policeman, customs, car, object height speed moving target information, application is very extensive.The RFID REID is a technology that is developing, problem such as also exist at present contradiction, the contradiction that label position cooperates with the read/write head position of capacity and speed and disturbed when reading.

Summary of the invention

The purpose of this utility model provides a kind of high power capacity read-write equipment and the comprehensive read apparatus of RFID and RFID 3 D read/write system that synthetic read write tag forms, cooperates corresponding program to form by RFID, part solves the contradiction of high power capacity and reading speed in the logistic information management, be subjected to the contradiction of putting position restriction attached to the label on the article, and the electronic tag problem that shielded and disturb.

Solution of the present utility model is: adopt RFID high power capacity read-write equipment, add three-dimensional RFID read apparatus, cooperate synthetic read write tag and read and write supervisory routine, computing machine or management equipment formation 3-D wireless radio-frequency recognition system accordingly.Described RFID high power capacity read-write equipment adopts the S6550 electronic label read/write of TI company.Described three-dimensional RFID read apparatus adopts in three IP-X double frequencies of iPico company apart from read head, and wherein the antenna surface of two read heads is parallel staggered relatively, perpendicular to ground, at a distance of 1.4 meters to 1.8 meters; The antenna surface of another read head is placed on the subsurface between the antenna surface of above-mentioned two read heads, is parallel to ground.Owing to read and carry data simultaneously apart from read head in three IP-X double frequencies, on equipment, set up networking component and sockets such as network interface card, adopt the TCPIP procotol, guarantee that three read heads can work simultaneously and correctly carry data.Described synthetic read write tag is placed envelope by high power capacity writing labels and the tiling of read-only identification (RFID) tag and is moulded card-like.Be reading of data more reliably, in the IP-X double frequency, on read head, install the anti-interference assembly of DSP additional.

The beneficial effects of the utility model are: after adopting such scheme, the details of article can be written in the label, and can read.The essential information that simultaneously can comprehensive, convenient, promptly gather article makes things convenient for the management of article.And can resist shielding, anti-interference adaptation than rugged surroundings.

Embodiment

The utility model is made up of the high power capacity read-write equipment 2a of RFID and three-dimensional read apparatus 2b and the synthetic read write tag of RFID, cooperates corresponding program and computing machine 1 to constitute RFID 3 D read/write system.(as Fig. 1)

Wherein the high power capacity read-write equipment 2a of RFID adopts the S6550 read write line of TI company to realize that its write-in program process flow diagram is seen Fig. 4 to the read-write of electronic tag high power capacity.

Wherein the three-dimensional read apparatus 2b of RFID adopt three independently in the IP-X double frequency of iPico company apart from read head, this product can provide the serviceability of low frequency (LF) system in the consumption media is arranged, and has the identical high data rate of ultrahigh frequency (UHF) system simultaneously.Dual-frequency system is not covered by human body, conducting liquid etc.Compare with other low frequency system, can reach farther operating distance, this mainly has benefited from being operated in the reverse link (label → read head) of 6.8MHz, and is more much higher than the forward link that is operated in 125kHz (read head → label).And this product has used the anti-collision agreement identical with the ultrahigh frequency product, can read 120 labels simultaneously, and read rate can reach for 30 label/seconds.Constitute (as Fig. 2) apart from read head by main frame 2b-1 and two integrated 2b-2 of tours antenna system and frock case 2b-3 in the IP-X double frequency of iPico.Its antenna system mainly is made of the cable of ring-type, and the plane formation antenna surface at cable place (100cm * 40cm).Main frame and antenna are encapsulated in the frock case.The antenna surface of two read heads is parallel staggered relatively, perpendicular to ground, at a distance of 1.4 meters to 1.8 meters; The antenna surface of another read head is placed on the subsurface between the antenna surface of above-mentioned two read heads, is parallel to ground.Three read heads are separate, and its data output is received hub by network interface card respectively and is connected with computing machine 1, and its data delivery adopts the TCPIP procotol.Above design makes the space that is arranged in three read heads and surrounds (all can be read computing machine 1 rapidly in any case the label of 140cm * 80cm * 40cm to 180cm * 100cm * 60cm) is placed.Be reading of data more reliably, install the anti-interference assembly of DSP additional on read head in the IP-X double frequency, this assembly adopts the high accuracy number filtering circuit of iPico company development, is installed at the receiving end of read head.
