Description
Technical field
The utility model relates to a kind of RFID label and adopts the printed circuit board of this label, relates in particular to a kind of split type passive RFID tags and adopts the printed circuit board of this label.
Background technology
In big events such as Aero-Space, to product code name and the independent assembly of paying are arranged, other product of equipment (containing) higher level, the product quality form of personal details is set up in requirement, product log should be set up when product assembling beginning, main record product is paid quality and the performance condition before dispatching from the factory, the quality problems that take place behind the product export, every content in the product log should have trackability, product log is responsible for preparing, filling in, preserve, file by production unit, guarantee in time to provide inquiry and use, and be responsible for providing copy by the requirement of general assembly unit.Every content in the product log should be in time, fill in exactly, and signature in accordance with regulations.The employing of product log has been played important effect to the supervision of batch changing management, product quality of product with reviewing.
The product quality form of personal details of aerospace field product employing at present all is the papery form of personal details basically, be the production unit paper products form of personal details different to the different product prepared beforehand according to code requirement, be responsible for record by technological process at the scene by the special messenger, import computing machine again and preserve, print paper-copy when needing and hand over general assembly unit.There is following shortcoming in existing record management method: (1) paperyization is filled in, and different product requires different table content, and preparation papery form of personal details increases cost, loses time; (2) the on-the-spot hand filling of papery form of personal details, standardization control is difficult, exists fill substance unclear easily; (3) the on-the-spot keeping of paper document is inconvenient, also needs input computer once more afterwards, increases work load, and promptness is not enough; (4) paper document inquiry and use are very inconvenient, and the papery form of personal details is difficult to decide with corresponding nation in kind simultaneously, and paper document is corresponding with printed circuit board to be the comparatively thing of difficulty of part; (5) after papery form of personal details copy was transferred to general assembly unit, applying unit was difficult to carry out timely and effectively quality analysis; (6) papery form of personal details content be difficult in time to have access to, the Authorized operation management of classification inquiry, additional modifications etc., it is very big constant to bring for outfield user debugging and quality check.
Along with the develop rapidly of electronic information technology, papery form of personal details electronization is the inexorable trend of development, how the electronics form of personal details is used for printed circuit board, and the scheme that can select has SD card, contact SIM card, passive RFID tags at present.These electronic products all have relatively large memory capacity, but SD card and contact SIM card connecting line is more, cost is high, processing is used complicatedly is embedded in that to use on the printed circuit board be not very suitable.
RFID is a kind of simple wireless system, is made up of an interrogator (or reader) and a lot of transponder (or label).The RF technology utilizes wireless radio frequency mode to carry out the noncontact bi-directional transfer of data between reader and radio-frequency card, to reach the purpose of Target Recognition and exchanges data.1), label (Tag, i.e. radio-frequency card) the most basic RF system is made up of three parts:: be made up of coupling element and chip, label contains built-in aerial, be used for and radio-frequency antenna between communicate.2), reader: the equipment that reads (in read-write card, can also write) label information; 3), radio-frequency antenna: between label and reader, transmit radiofrequency signal.
The RFID label is commonly called as electronic tag, also claim transponder (tag, transponder, responder), can be divided into active (active) and passive type (passive) two big classes according to working method, passive type RFID label is made up of label chip and label antenna or coil, utilize inductive coupling or electromagnetic backscatter coupling principle realize and read write line between communication.Unique coding of storage is generally 64bits, 96bits even higher in the RFID label, and its address space is much higher than the space that bar code can provide, and therefore can realize the article code of single grade.Enter the zone of action of read write line when the RFID label, just can produce the induced electricity potential difference at the label antenna two ends according to inductive coupling principle (in the reach of near field) or electromagnetic backscatter coupling principle (in the reach of far field), and in the label chip path, form weak current, if this strength of current surpasses a threshold value, just will activate RFID label chip circuit working, thereby the storer in the label chip is carried out read/write operation, microcontroller can also further add such as sophisticated functionss such as password or anti-collision algorithms, is suitable for very much making the printed circuit board electron form of personal details.
The RFID label that is applied in article supervision field at present substantially all is the passive soft label of RFID, the soft label of RFID is printed on the metal induction antenna on the soft materials such as paper, PVC film exactly, IC chip back-off is encapsulated in and forms the RFID label on the induction antenna, again the soft label of RFID is coated with and is covered with gum, can directly glue when specifically using and be posted on the article.
The soft label of RFID of band gum, its advantage is not need printed circuit board to anticipate, and directly pastes on printed circuit board and uses.The shortcoming that exists is: paste for the soft label of RFID in the space that will increase certain area on (1) printed circuit board, is difficult to satisfy for small-sized or special-shaped printed circuit board; (2) RFID soft label by glue on printed circuit board, be not easy to printed circuit board and stand the cleaning of solvent, simultaneously when printed circuit board environmental test and use, because the factor of environmental stress causes the soft label of RFID to come off easily or label chip is connected problems such as not smooth with induction antenna; (3) the soft label induction antenna of RFID is an electric conductor, in case the damage or the meeting that comes off produce electric fifth wheel; (4) electric parameter of the soft label of RFID is subjected to the influence of printed circuit board surrounding enviroment easily; (5) the soft label induction antenna of RFID itself is exactly that a telefault exists the electric parameter to printed circuit board itself to exert an influence sometimes.
If the passive RFID tags induction antenna is directly designed on printed circuit board, there is following point equally: will increase bigger space on (1) printed circuit board and lay, be difficult to satisfy for small-sized or special-shaped printed circuit board for RFID label induction antenna; (2) design of RFID label induction antenna has professional electric parameter requirement, and the media environment of the shape of induction antenna and attached work all can be relevant, and this increases a lot of work difficulty will for the Printed Circuit Board Design personnel; (3) design of RFID label induction antenna exists the electric parameter to printed circuit board itself to exert an influence on printed circuit board sometimes; (4) the RFID label induction antenna of design on printed circuit board is various, does not utilize standardization to use.Therefore the printed circuit board that is necessary to provide split type passive RFID tags and adopts this label is avoided induction antenna to take installing space and is reached the shortcoming that easily causes interference.
