Abstract
The utility model relates to a wireless radio frequency tag embedded into a specific ear tag of a commercial pig. The wireless radio frequency tag comprises an antenna which is connected with a circuit chip, wherein the antenna comprises a circular coil which is formed by encircling a metal foil of 5mm to 6mm in width; an opening is formed on the circular coil; the metal foils at two sides of the opening are connected with the circuit chip; two semicircular metal foil lines are symmetrically arranged around the outer side of the circular coil; one ends of the two semicircular metal foil lines are respectively connected with the metal foils at two sides of the opening of the circular coil. According to the wireless radio frequency tag, by designing a circular antenna, an optimal receiving a transmission distance is realized under the condition that the specific ear tag of the commercial pig is relatively small, and the reading and writing distance can be 80cm; a special annular antenna and a load module are designed according to the features of the specific ear tag of the commercial pig, so that the influence of the environment to the performance of the antenna is minimized.
Description
Technical field
The utility model relates to a kind of radio frequency label that is built in the special-purpose ear tag of market pig, has improved recognition stability by the design that changes antenna, and the recognition distance can reach more than the 80CM.
Background technology
At society, the application demand of radio frequency label is outstanding all the more, and its application development extends to the application of agricultural industry, particularly breeding stock and dairy stock cultivation unit always.Less radio-frequency is increasingly mature in the application of other industry at present, but because the agricultural industry working environment is comparatively complicated and simple and crude, the physique of livestock live body is to the work influence of less radio-frequency, and the shape and size of ear tag are national standards simultaneously; Therefore, so that currently marketed most radio frequency label is not fully up to expectations at the effect of agricultural industry, and can't mate the livestock tag that state compulsion uses fully, even by force common radio frequency label is put into livestock tag, practical application effect can't reach the groundwork demand at all, the form of performance is that recognition stability and recognition distance are low, can not satisfy job requirement.
Summary of the invention
The purpose of this utility model is to propose a kind of wireless RF label technique scheme that is built in the special-purpose ear tag of market pig, has improved recognition stability by the design that changes antenna, and the recognition distance can reach more than the 80CM.
To achieve these goals, the technical solution of the utility model is: a kind of radio frequency label that is built in the special-purpose ear tag of market pig, comprise circuit chip and the antenna that is connected with circuit chip, described antenna comprises that one is that 5mm to 6mm metal forming is enclosed around the circular coil that forms by live width, at the circular coil opening that to be provided with a width be 0.8mm to 1mm, the metal forming of opening both sides is connected with circuit chip, be symmetrically arranged with two semi arch tinsel cords around the circular coil outside, an end of two semi arch tinsel cords is connected on the metal forming of circular coil opening both sides.
The live width of described two semi arch tinsel cords is 0.5mm to 0.8mm, and the spacing of two semi arch tinsel cords and circular coil is 2mm to 2.3mm.
Be provided with the saturating groove of " individual " font on the tinsel cord plane on described circular coil opening opposite, the groove width of groove is 0.8mm to 1mm thoroughly, and the live width of the circular coil on the saturating groove of individual font top remains on 0.8mm to 1mm.
The beneficial effects of the utility model are: utilize the circular antenna design, than under the small size, realize best reception and transmitting range at the special-purpose ear tag of market pig, its reading/writing distance can be accomplished〉80cm; According to the feature of the special-purpose ear tag body of energy market pig, the loop antenna that particular design is special, and load blocks are so that environment minimizing the antenna performance impact.
Below in conjunction with drawings and Examples the utility model being done one describes in detail.

Embodiment
A kind of radio frequency label that is built in the special-purpose ear tag of market pig, referring to Fig. 1 and Fig. 2, a circular market pig ear tag body 1 is arranged, there is pin hole 1-1 at the center of circular ear tag body, in the ear tag body, be provided with radio frequency label 2, described radio frequency label comprises circuit chip 2-1 and the antenna 2-2 that is connected with circuit chip, and antenna is attached to (for example on the glass fabric of epoxy resin plate) on the film substrate by the method for circuit board etching, and circuit chip is by on the mount technology welding antenna.Be coated with the PET film at circuit chip and antenna, the surface attachment of the non-antenna surface of described film substrate has glue, be fixed in the special-purpose ear tag body of market pig with the film substrate of circuit chip and the antenna mode by injection moulding, described antenna comprises that one is the circular coil 2-2-1 that 5mm to 6mm metal forming forms around pin hole by live width, at the circular coil opening 2-2-2 that to be provided with a width be 0.8mm to 1mm, the metal forming of opening both sides is connected with circuit chip, be symmetrically arranged with two semi arch tinsel cord 2-2-3 around the circular coil outside, an end of two semi arch tinsel cords is connected on the metal forming of circular coil opening both sides.
The live width of two semi arch tinsel cords is 0.5mm to 0.8mm described in the embodiment, and the spacing 2-2-4 of two semi arch tinsel cords and circular coil is 2mm to 2.3mm.
Among the embodiment, be provided with the saturating groove 2-2-5 of " individual " font on the tinsel cord plane on described circular coil opening opposite, the groove width of groove is 0.8mm to 1mm thoroughly, and the live width 2-2-6 of the circular coil on the saturating groove of individual font top remains on 0.8mm to 1mm.
The present embodiment utilizes the circular antenna design, and the proportion responding range is the ultrahigh frequency radio frequency chip of 920～925MHz, by special Antenna Design, makes the response frequency of label obtain a certain amount of frequency compensation.When recognizer was launched the electromagnetic wave of 920～925MHz, the label respective tones was named a person for a particular job above this numerical value, although the response frequency consumes a part like the compositions such as water in the animal body, still can return out the electromagnetic wave of 920～925MHz.Because above-mentioned design, after label is worn on the animal body, still can guarantee that the optimal response frequency drops in 920～925MHz standard bands, be identified at the performance reduction that causes because being interfered behind the animal body even the situation about losing efficacy of being worn on thereby solve common UHF electronic.
The present embodiment than under the small size, is realized best reception and transmitting range at the special-purpose ear tag of market pig, and its reading/writing distance can be accomplished〉80cm; According to the feature of the special-purpose ear tag body of energy market pig, the loop antenna that particular design is special, and load blocks are so that environment minimizing the antenna performance impact.
