A kind of RFID label
Technical field
The utility model relates to electronic equipment, relates in particular to a kind of RFID label.
Background technology
The identification of RFID electronic tag and data transmission are to carry out at a two-dimentional plane space substantially.Therefore, the position between RFID electronic tag and tag recognition equipment, need to and adjust according to certain requirement planning.Once especially the identification apparatus such as RFID card-reading machine fixing after, the built-in label antenna face of electronic tag must and the antenna surface of the identification apparatus such as card-reading machine, in parallel position, could obtain best identification result.This is because of existing RFID electronic tag, and its inner label antenna is all the two-dimensional approach that adopts planar design substantially.The antenna surface that is electronic tag must be with the antenna of identification apparatus when the same axial location, and the energy that label antenna obtains from identification apparatus antenna is maximum.
But, due to RFID label in use, its outward appearance, position etc. are not what fix, identification terminals such as card-reading apparatus (note: except hand-held class identification terminal) have been fixed often and have been debugged, so, in the occasions of many uses RFID, in dynamic RFID label and between (the referring to RFID Card Reader identification terminal or existing equipment itself) of static state Card Reader identification terminal whole drawbacks of accurate identification of existence more or less all.
Utility model content
In order to solve the problems of the prior art, the utility model provides a kind of RFID label.
The utility model provides a kind of RFID label, the RFID chip, the antenna that comprise housing and be positioned at described housing, described antenna is three, one of them antenna is vertically connected at described RFID chip front side, two other antenna is vertically connected at respectively described RFID chip two sides, this RFID label also comprises support link, and described support link one end is connected with described housing, and the described support link other end is provided with fixed mechanism.
As further improvement of the utility model, described fixed mechanism is sucker or band.
As further improvement of the utility model, described support link one end and described housing are fixed by screw.
As further improvement of the utility model, described housing outer surface is enclosed with cushion.
As further improvement of the utility model, described cushion is made by silica gel material.
As further improvement of the utility model, described antenna is spring shape.
As further improvement of the utility model, described antenna consists of at the gold and silver chromium alloy layer of copper base outside surface copper base and plating.
As further improvement of the utility model, described gold and silver chromium alloy layer thickness is between 0.05mm to 0.08mm.
The beneficial effects of the utility model are: RFID label construction compactness of the present utility model, framework advantages of simple, volume are small and exquisite, can multi-angle, multi-faceted detection, and good stability, verification and measurement ratio is high, and convenient fixing, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of RFID label, the RFID chip 2, the antenna 3 that comprise housing 1 and be positioned at described housing 1, described antenna 3 is three, one of them antenna 3 is vertically connected at described RFID chip 2 fronts, and two other antenna 3 is vertically connected at respectively described RFID chip 2 two sides.
Because an antenna 3 is vertically connected at described RFID chip 2 fronts, two other antenna 3 is vertically connected at respectively described RFID chip 2 two sides, so, so long as within the scope of the signal strength of card reader, RFID electronic tag is placed in any case, can be identified smoothly detection.And needn't, as the common label that adopts ordinary two dimensional flat plane antenna, must make the antenna of label antenna and card-reading apparatus just can be identified detection when corresponding axial location.And RFID label construction compactness of the present utility model, framework advantages of simple, volume are small and exquisite, can multi-angle, multi-facetedly detect identification, good stability, detects discrimination high.
This RFID label also comprises support link 4, and described support link 4 one end are connected with described housing 1, and described support link 4 other ends are provided with fixed mechanism.
Described fixed mechanism can be sucker 5 or band, and described support link 4 one end and described housing 1 are fixed by screw.
In the full used time, by sucker 5, this RFID label can be fixed in car, or by band, this RFID label be tied up on object, convenient fixing, increase work efficiency.
Described housing outer surface is enclosed with cushion, and this cushion is made by silica gel material, and this cushion provides shock-absorbing function, prevents that this RFID label from surprisingly dropping and damaged.
Described antenna 3 is spring shape, and impact and pressure that can elastic buffer outside adapt to multiple rugged surroundings and uses.
Described antenna 3 consists of at the gold and silver chromium alloy layer of copper base outside surface copper base and plating, and described gold and silver chromium alloy layer thickness, between 0.05mm to 0.08mm, has guaranteed the good reading performance of antenna 3, can reach farthest 10 meters of distances.
RFID label of the present utility model have penetrability good, can batch scanning etc. feature, can be applied in logistics field, while being especially open to the custom, there is fine convenience.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
