Description
Technical field
The utility model relates to the electronic tag of a kind of RFID or EAS, particularly relates to a kind of electronic tag that can be attached to the metal surface.
Background technology
RFID is the abbreviation of the English (Radio Frequency Identification) of REID.REID is a kind of automatic identification technology that begins to rise the nineties in 20th century.Problems such as at present, China's REID and application are in elementary developing stage, exist technical merit not high, and standard criterion is imperfect.Simultaneously, China's REID has vast potential for future development and huge market potential again.Relatively and barcode technology, the development of REID and the popularization of application will be the field technology revolutions that China discerns industry automatically.
REID is one and utilizes radiofrequency signal to realize that by space coupling (alternating magnetic field or electromagnetic field) contactless information transmission and the information of passing through to be transmitted reach the technology of identifying purpose.Radio-frequency recognition system is made up of electronic tag (radio-frequency (RF) tag) and reader usually.The electronic data that has certain format in the electronic tag, normal with this sign information as article to be identified.In the application with electronic tag attached on the article to be identified, as the electronic marker of article to be identified.Reader and electronic tag can be by the communication protocol transinformations of agreement, and common situation is to send order by reader to electronic tag, and electronic tag is according to the order of the reader of receiving, the sign data of internal memory are returned to reader.This communication is under contactless mode, utilizes the space coupling of alternating magnetic field or electromagnetic field and radiofrequency signal modulation and demodulation technology to realize.
Electronic tag has various shapes, but not the requirement that arbitrary shape can both satisfy reading distance and frequency of operation, must be according to the principle of work of system, i.e. magnetic field coupling (transformer principle) is electromagnetic field couples (Principles of Radar) still, designs suitable antenna shapes and size.Electronic tag is made up of label antenna (or coil) and label chip usually.Label chip promptly is equivalent to one and has the monolithic system (SoC) that radio transmission-receiving function adds store function again.From the angle of pure technology, the core of REID is at electronic tag, and reader is that the design according to electronic tag designs.Though the price of electronic tag is low more than reader in radio-frequency recognition system, generally, the quantity of electronic tag is very big in application, especially in the logistical applications, electronic tag is by being magnanimity and being disposable that it is many that the quantity of reader then will be lacked relatively.
Because electronic tag is applied in the fields such as automatic identification of commodity logistic track, antitheft, article anti-counterfeit, animal, article, it is that metal is made that but many article are arranged, the ordinary electronic label is attached to the metal surface, can't carry out normal communication between read write line and the electronic tag, radiowave forms eddy current in the metal surface, heating dissipates the power of radiowave in the metal surface, make the resonance frequency of electronic tag higher, the energy that obtains reduces in a large number, thereby can't carry out operate as normal, this drawbacks limit the application of ordinary electronic label on the metal surface.
To be attached to the metal surface to electronic tag, when requiring electronic tag to carry out reading and writing data, little to the loss of radio signal; Require electronic tag crooked easily, so that be attached to some crooked metal surfaces.
Summary of the invention
The purpose of this utility model is exactly that a kind of electronic tag that is attached to the metal surface is provided in order to address the above problem.
The purpose of this utility model can be achieved through the following technical solutions: the electronic tag that is attached to the metal surface; it is characterized in that; it comprises magnetic piece, adhered layer, the surface insulation protective seam of ordinary electronic label, high magnetic flux; described ordinary electronic label is close to the one side of the magnetic piece of high magnetic flux; described adhered layer is close to the another side of the magnetic piece of high magnetic flux; the size of the magnetic piece of described high magnetic flux is greater than the size of ordinary electronic label, and described surface insulation protective seam is coated on around the ordinary electronic label.
Described ordinary electronic label comprises common RFID electronic tag, and this electronic tag is made up of coil, electric capacity, RFID chip, and this electric capacity can be built-in chip type electric capacity or external electric capacity.
Described ordinary electronic label comprises electronic tag high frequency or low frequency.
The magnetic piece of described high magnetic flux can adopt the soft magnetic material of moulding, and also can adopt rigid magnetic material.
The magnetic piece of described high magnetic flux can adopt high frequency material, also can adopt the low frequency material.
Described adhered layer can be an adhesive sticker, or other permanent glue.
Described insulating protective layer can be that soft pebble drips glue, also can be rigid plastic casing.
The described frequency of operation that is attached to the electronic tag of metal surface is controlled by thickness, density or the material of the magnetic piece that changes high magnetic flux.
The described profile that is attached to the electronic tag of metal surface comprises rectangle, triangular form or circle.
Described RFID chip can be selected the RFID chip of disposable type for use according to the actual functional capability requirement.
Adopt the produced electronic tag that is attached to the metal surface of above technical scheme, can carry out normal data message read-write operation, have little, soft, thin, the crooked easily characteristics of radio signal loss with read write line, economical and practical, have good market outlook.
Description of drawings
Fig. 1 is attached to the structural representation of the electronic tag of metal surface for the utility model;
Wherein: 1-ordinary electronic label, the magnetic piece of 2-high magnetic flux, 3-adhered layer, 4-surface insulation protective seam, the 5-magnetic line of force, 6-metal covering object.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
