Description

Intelligent electric meter label

Technical field

The utility model relates to a kind of e-management label, particularly discloses a kind of intelligent electric meter label.

Background technology

The development of RFID technique, advances the continuous renewal of data message, the discernible identity information that allowed more article have, and greatly improves the efficiency of flow of goods.Ammeter is as the end product of intelligent grid, and its level of informatization is self-evident, is therefore necessary to the electronic ID card of an ammeter energy identification, improves the speed of ammeter in circulation and accuracy.

Ammeter, as "smart" products, can wireless signal emission be an essential condition.Radio meter register is a valuable feature of intelligent electric meter, there is a large amount of capacitor and inductors the transmitter module inside of its specific 270KHz, and ammeter itself also has a large amount of prototype parts to form, the circuit structure of its complexity have impact on the normal transmission of uhf electromagnetic wave greatly.

Nowadays most ammeter producer is all the public version antenna of attachment, and this antenna advantage is applied widely, belongs to popularity label antenna, and shortcoming does not clearly have specific aim exactly.When using this type of label, do not have obvious sensitivity curve when single label test is attached on ammeter, performance drops sharply to 10% of former label; The test of many labels case dress, can only under enough strong readout power and abundant sweep time situation, and can barely read FCL label information, be all in most cases normally to read.Such as, the reading that just there will be vast scale when lane testing phenomenon not, need during hand-hold scanning repeatedly to scan just can sweep complete, can frequent skip when to cross safety check.

Therefore, be necessary to design a New-type label antenna to this particular application of ammeter, when being mounted on ammeter, its resonance optimum resonance point is in read write line transmit frequency range.

Summary of the invention

The purpose of this utility model is for problems of the prior art, the skip phenomenon of appearance during in-out-storehouse management is carried out when solving common label attachment ammeter, a kind of stable performance is provided, the interference effectively avoiding the inner complicated circuit of ammeter to cause uhf electromagnetic wave, has the intelligent electric meter label of excellent sensitivity.

The utility model is achieved in that a kind of intelligent electric meter label, comprise chip, antenna, base material, it is characterized in that: described antenna comprises return rings, first and raises one's arm, second to raise one's arm, described first raises one's arm to raise one's arm the identical and Opposite direction connection of structure in the both sides of described return rings with second; Described first raises one's arm comprises the first transverse arm, the first vertical arm, the second transverse arm, the second vertical arm, the 3rd transverse arm, the 3rd vertical arm, the 4th transverse arm, the rectangular arm that are connected successively, one end of described first transverse arm is connected with described return rings, and wherein said first, second, third, fourth transverse arm is respectively perpendicular to described first, second, third vertical arm; Be parallel to each other between described first, second, third vertical arm; Described first vertical spacing Wa between arm and described return rings, the spacing Wb between the first vertical arm and the second vertical arm, spacing Wc between the second vertical arm and the 3rd vertical arm, the 3rd vertical spacing Wd between arm and the rectangular arm ratio between this is: Wa:Wb:Wc:Wd=1:1.2:15:2.This described first to raise one's arm, the second reverse setting of raising one's arm, offset the interference of ammeter internal radio frequency module electromagnetic field, and frequency dependent characteristic and the impedance operator of label antenna is improved by the unequal-interval structure between each vertical arm, greatly reduce and be subject to the inner complex electromagnetic environment effect of ammeter.

The return rings of described antenna is straight-flanked ring, and described chip is positioned at the central upper portion of described straight-flanked ring.

The length of described antenna is 58mm ± 2mm, and the width of described antenna is 14mm ± 1mm.

The outer length of the return rings of described antenna is 10mm ± 2mm, and the external width of return rings is 6.5mm ± 1mm.

The beneficial effects of the utility model are: the interference of the structures counter ammeter internal radio frequency module electromagnetic field of oppositely raising one's arm of raising one's arm with second of raising one's arm by described first, and frequency dependent characteristic and the impedance operator of label antenna is improved by the unequal-interval structure between each vertical arm, greatly reduce and be subject to the inner complex electromagnetic environment effect of ammeter.This practical stable performance, the interference effectively avoiding the inner complicated circuit of ammeter to cause uhf electromagnetic wave, has excellent sensitivity.
