The anti-interference cover comprises a shading body and a supporting structure, wherein the shading body is made from an insulating material and can be used for shading the electronic tag; the supporting structure can be connected with a windscreen to be glued with a surface; being relative to a position plane of the electronic tag and having an isolated space with the electronic tag, the shading body is internally provided with an conductive structure layer, the area of which is larger than that of an electronic tag projection region; and the isolated space is internally filled with an insulating medium. The electronic tag is combined with the anti-interference cover into an integral structure in a positioning way so as to form the anti-interference vehicle electronic tag. The experiment shows that the anti-interference cover and the anti-interference electronic tag can effectively avoid and eliminate interference factors which can influence the normal read/write and use of the electronic tag since the hands, the other conductive materials or the objects are near to or shade the electronic tag and the like when using the RFID electronic tag, thereby having satisfied effect.
Description
Technical field
The utility model relates to a kind of anti-interference structure that can prevent or eliminate automobile specified RFID electronic tag disturbing factor, and the auto electronic label construction with antijamming capability.
Background technology
RFID (Radio Frequency Identification, radio-frequency (RF) identification) electronic tag, because of having remote and wireless read/write and the convenient function of upgrading institute's recorded information of revising, and be easy to carry about with one and deposit, and advantages such as waterproof, protection against the tide, shatter-resistant are arranged, in motor vehicle and traffic administration, be widely adopted day by day, can significantly improve motor vehicle and traffic management level.In actual use, generally all be that these electronic tags are settled (pasting) inner face at windshield, so that when charging, statistics, management etc., discern and read/write by corollary equipment.Find in the practice, because the own characteristic and the limitation of the radio RF recognition technology that RFID adopts, when have a mind to or by mistake with human body (as hand etc.) or other conductive material, article near or cover this electronic tag, the capital makes electronic tag discerned to produce with the microwave signal of read/write and disturbs, even can have a strong impact on normal and correct use of electronic tag.
The utility model content
At above-mentioned situation, the utility model will provide a kind of can prevent or eliminate the anti-tampering cover of automobile specified RFID electronic tag disturbing factor, and electronic tag can normally be used without interruption.On this basis, the utility model also will provide a kind of automobile-use electronic tag that can have antijamming capability.
In the anti-tampering cover structure of auto electronic label of the present utility model, there is one can form the insulating material shade body that blocks and have the supporting construction that can engage the face of pasting to electronic tag with vehicle windscreen, inboard relative with the electronic tag position plane and maintain the mode of insulating space at the shade body, be provided with the conductive structure layer of an area, be filled with dielectric in the insulating space greater than electronic tag view field.
Said shade body in the above-mentioned anti-tampering cover structure, multiple different structure choice form can be arranged, for example, can be adopted as and only block and the open version of periphery as the plane, also can adopt except that block on the plane, around partly or entirely also barrier structure being arranged of edge and being have the flute profile or the bowl-type cover buckle structure body of interior concave space that can the holding electronic label, this moment, said and conductive structure layer that maintain insulating space setting relative with the electronic tag plane then was arranged in the interior concave space of this flute profile or bowl-type.
Said conductive structure layer in the said structure is good with lamella, the film layer structure of selecting metal materials such as the good copper of electric conductivity (as copper-clad plate etc.), iron, aluminium (as aluminium foil etc.) or alloy generally.
In the anti-tampering cover structure of above-mentioned form, the support distances and the said insulating space distance that needs to keep of this supporting construction on the shade body are adapted, thereby make this conductive structure layer can be along the inside bottom surface setting of shade body, both convenient processing, also help reducing the structural volume of anti-tampering cover, the convenient use.Technical conditions such as frequency of using according to present RFID and/or antenna, the plan range of this insulating space generally can be set to 2～14 millimeters between said conductive structure layer and electronic tag.
According to the applied microwave transmission characteristics of RFID, it is necessary filling dielectric in the insulating space of above-mentioned anti-tampering cover.Said dielectric is except that can adopting materials such as dense forms such as the common sheet as macromolecular materials such as ply of paper, PVC, plate or loose foams, and more easy is the space that also can directly be adopted as air insulated.
On the said structure basis, with the be combined as a whole structure of formula of the anti-tampering cover of electronic tag and said structure, promptly a kind of auto electronic label, the actual use of will being more convenient for antijamming capability.For example, in the basic structure of said anti-interference auto electronic label, can can form the insulating material shade body that blocks and have the above-mentioned form of the supporting construction that can engage the face of pasting to electronic tag for there being one with vehicle windscreen, paste in supporting construction and to be provided with the support structure that is used to put electronic tag within the face, be provided with the conductive structure layer of an area in the inboard and mode that maintain said insulating space relative of shade body, and in insulating space, be filled with the dielectric of air or other appropriate format greater than electronic tag view field with the electronic tag support plane of this support structure.
Wherein said this shade body, can adopt above-mentioned only blocking and the open version of periphery equally as the plane, or adopt except that block on the plane, around partly or entirely also barrier structure being arranged of edge and being have the flute profile or the bowl-type cover buckle structure body of interior concave space that can the holding electronic label.
Result of the test shows, after adopting the anti-tampering cover of the utility model said structure form, can effectively prevent and eliminate the RFID electronic tag in use because of hand or other conductive material, object near or coverage etc. can influence the disturbing factor of electronic tag normal read and use, have satisfied effect.
Below, the utility model foregoing is described in further detail again by embodiment by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
