Abstract
The invention discloses a high-density ultrahigh frequency radio frequency tag detection device and relates to the technical field of radio frequency identification. The device comprises a tag queue formed by arranging a plurality of radio frequency tags, a substrate for transmitting the radio frequency tags, and a detector antenna which is fixed on the ground and is arranged above the substrate. The device is structurally characterized in that: a metal plate is fixedly arranged on the upper surface or the lower surface of the tag queue below the detector antenna; and a testing window of which the size is larger than that of the radio frequency tag is arranged on the metal plate, and is aligned with the detector antenna. Only a specific tag can normally respond to a detector signal by utilizing an electromagnetic shielding technology, and the device has the characteristics of simple structure, long service life of equipment and high detection reliability.
Description
Technical field
The present invention relates to radio RF recognition technology field, be particularly applicable to the pick-up unit of high-density ultra-high frequency radio-frequency label.
Background technology
RFID is the abbreviation of Redio Frequency Identification, i.e. radio RF recognition technology, and this technology is a kind of new technology of automatic identification field, can be applied in the multiple fields such as logistic track, certificate license be false proof.The ultrahigh frequency UHF even RFID label of higher frequency is the developing direction of RFID label technique, and one of feature of uhf band label is that reading/writing distance is far away, and this brings great convenience to application.
The fast detecting of carrying out product in the large-scale production of RFID electronic tag is a problem that needs solution.Because the RFID label reading/writing distance of UHF frequency is far away, make being detected as for a difficult problem of label in extensive, high density production: in production run, label is compact arranged, because detecting device coverage is difficult to greatly determine current data are returned to (data may be returned by adjacent label) by which label, thereby cannot complete the accurate detection of product.
In prior art, normally move card reader antenna by mechanical arm, make antenna complete function, the Performance Detection of label near detected label.Such method has two significant shortcomings, and the one, the kinematic system more complicated of antenna, another is that the antenna and the stube cable that move easily damage.
Summary of the invention
In order to overcome the shortcoming existing in above-mentioned prior art, the object of this invention is to provide a kind of pick-up unit for high-density ultra-high frequency radio-frequency label.It utilizes electromangnetic spectrum to make only to have the specific label can normal response detector signal, has feature simple in structure, that service life of equipment is long, detecting reliability is high.
In order to reach foregoing invention object, technical scheme of the present invention realizes as follows:
For a pick-up unit for high-density ultra-high frequency radio-frequency label, it comprises the tag queue that is arranged in by several radio-frequency (RF) tag and transmits the base material of radio-frequency (RF) tag and fix and be placed in the detector antenna of base material top with ground.Its design feature is, upper surface or the lower surface of the below that is positioned at detector antenna of described tag queue are fixed with sheet metal, and sheet metal is provided with the test window that is greater than radio-frequency (RF) tag size, and test window is just to detector antenna.
In above-mentioned detection device, described sheet metal adopts masking foil material and carries out plastic packaging.
The present invention has been owing to having adopted said structure, allows label to be checked in turn completely in test window, completes the testing to specify labels.Compared with the existing technology, the present invention has feature simple in structure, that service life of equipment is long, detecting reliability is high.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Brief description of the drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Referring to accompanying drawing, pick-up unit of the present invention comprises the tag queue that is arranged in by several radio-frequency (RF) tag 2 and transmits the base material 1 of radio-frequency (RF) tag 2 and fix and be placed in the detector antenna 3 of base material 1 top with ground.The upper surface of the below that is positioned at detector antenna 3 of tag queue or lower surface are fixed with the sheet metal 4 that adopts masking foil material and carry out plastic packaging.Sheet metal 4 is provided with the test window 5 that is greater than radio-frequency (RF) tag 2 sizes, and test window 5 is just to detector antenna 3.
When the present invention uses, be close to a sheet metal 4 at tag queue upper surface or lower surface, open a test window 5 more bigger than radio-frequency (RF) tag 2 sizes on sheet metal 4, detector antenna 3 is suspended at test window 5 tops and reads radio-frequency (RF) tag 2 to window direction.Can greatly decay and paste the performance of radio-frequency (RF) tag 2 in its surface due to sheet metal 4, the radio-frequency (RF) tag 2 of being close to sheet metal 4 so all equal cisco unity malfunction under certain conditions.And the radio-frequency (RF) tag 2 that is placed in the test window 5 of offering on sheet metal 4 is because its surrounding and sheet metal 4 have certain spacing, what the performance loss of this radio-frequency (RF) tag 2 can be not very is serious, completes and can detect thereby can read normally.When tag queue is in the time that sheet metal moves for 4 times, radio-frequency (RF) tag 2 in test window 5 can be read by detecting device antenna 3 completely, other does not enter the cisco unity malfunction of radio-frequency (RF) tag 2 of test window 5 completely, thereby guarantee only to have specific radio-frequency (RF) tag 2 to reply detector signal, ensured normally carrying out of testing.
When the present invention works, in order to ensure best monitoring effect, can adjust detecting device power and detector antenna 3 and can stable detection be arranged in the radio-frequency (RF) tag 2 of test window 5 and can not misread adjacent radio-frequency (RF) tag 2 apart from the distance of radio-frequency (RF) tag 2, the size of adjustable test window 5 also necessary time.
Claims (2)
1. the pick-up unit for high-density ultra-high frequency radio-frequency label, it comprises the tag queue that is arranged in by several radio-frequency (RF) tag (2) and transmits the base material (1) of radio-frequency (RF) tag (2) and fix and be placed in the detector antenna (3) of base material (1) top with ground, it is characterized in that, upper surface or the lower surface of the below that is positioned at detector antenna (3) of described tag queue are fixed with sheet metal (4), sheet metal (4) is provided with the test window (5) that is greater than radio-frequency (RF) tag (2) size, test window (5) is just to detector antenna (3).
2. the pick-up unit for high-density ultra-high frequency radio-frequency label according to claim 1, is characterized in that, described sheet metal (4) adopts masking foil material and carries out plastic packaging.
