Description
Technical field
The utility model relates to a kind of ultrahigh frequency sensor label of the narrow that is combined by amorphous soft magnetic material.
Background technology
In markets such as pharmacy, supermarket, bookstores, because the Retail commodity volume is less, be easier to be carried secretly go out, will cause economic loss to businessman like this.Therefore, solving that Retail commodity sells in markets such as bookstore, pharmacy, supermarket is not the thing that businessmans generally are concerned about by " stealing ".Simultaneously, along with the appearance of Internet of Things, also more and more outstanding for the logistics control and the managerial requirement of commodity amount.At present, at commodity, books etc. in the antitheft or administrative skill, the antitheft electronic tag that is used for commodity is low frequency tags normally.And the ultrahigh frequency reach is wide, and it is fast to transmit data speed, can be used for the data storage management of commodity usually.Ultrahigh frequency label of the prior art often bigger than normal being difficult to of volume hide, if anti-theft tag and this ultrahigh frequency data storage label are made of one, remove after being easy to be found, thereby influence the management of commodity.
The utility model content
The technical problems to be solved in the utility model is: in order to address the above problem, the utility model provides a kind of volume less, and takes into account the ultrahigh frequency sensor label of the narrow that is combined by amorphous soft magnetic material of antitheft and management function.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of ultrahigh frequency sensor label of the narrow that is combined by amorphous soft magnetic material, comprise and be used for first antenna that ultrahigh frequency surveys and be used for low-frequency acquisition and strengthen second antenna of first antenna at the detection performance of ultrahigh frequency, first antenna has emptying aperture and the radio frequency chip that is arranged on first antenna middle part, described radio frequency chip is arranged on the horizontal middle and lower part of first antenna, second antenna has the charging-erasing magnetic sheet that substrate that amorphous soft magnetic material makes and a plurality of half-hard magnetic material that is intervally arranged are made, and described charging-erasing magnetic sheet is pasted on the same surface of substrate.
In order to strengthen the detection performance of label at hyper band, contact is connected described first antenna with second antenna.
In order to guarantee the detection perception of second antenna in low-frequency range, the length of described charging-erasing magnetic sheet is 5mm～20mm, width is 0.5mm～3mm, the length of described substrate is 60mm～200mm, width is 0.5mm～3mm, equidistantly arrange at length direction between each charging-erasing magnetic sheet, described spacing is 2mm～10mm.
In order to guarantee the detection perception of first antenna at hyper band, the length of described first antenna is 90mm～100mm, width is 2mm～4mm, and the width of described radio frequency chip is 0.5mm～1.5mm, and the width of described emptying aperture is 0.5mm～1.5mm.
First antenna is used for the storage administration of data, and it is antitheft that second antenna is used for electromagnetic wave.Detect to the low frequency generation alternating magnetic field of 20KHz with 10Hz when detecting antenna, detected object is second antenna, and second antenna promptly is a permalloy soft magnetic stripe with precipitous magnetic hysteresis loop.In the time of in the middle of soft magnetic stripe is positioned at the alternating magnetic field that emitting antenna produces, its polarity is by remagnetization periodically.Magnetic flux density B in the soft magnetic stripe is adding under the magnetic field intensity H effect, does near the non-linear jump of leap " 0 " and changes, and having produced frequency thus is the harmonic wave of emitting antenna fundamental frequency, and these harmonic waves are received antenna and receive and handle back generation alerting signal.When hyper band was worked, the attribute of second antenna became metal, and the less radio-frequency rfid interrogator in first antenna continues to send out the signal of certain frequency by read write line.When label entered magnetic field, passive label relied on the energy that induction current obtained to send out the product information that is stored in the chip, and perhaps active label initiatively sends the signal of a certain frequency; After reading and writing device antenna in the less radio-frequency rfid interrogator reads information subsequently, data transmission is carried out relevant data processing to CIS.
The beneficial effects of the utility model are, the ultrahigh frequency sensor label of a kind of narrow that combines by amorphous soft magnetic material of the utility model, the substrate of second antenna adopts amorphous soft magnetic material to make, this material has high magnetic property, especially magnetic property is the strongest in low-frequency range 1Hz-7500Hz, has guaranteed the electromagnetic wave anti-theft feature of label; The label profile is long and narrow, and volume is less, helps guaranteeing confidentiality; Second antenna is when high band, and attribute becomes metal, strengthens the detection performance of first antenna, thereby has dwindled the overall volume of label.
