A kind of EAS anti-theft electronic tag【Technical field】
The utility model relates to a kind of EAS electronic goods anti-stealing technology field more particularly to a kind of EAS theft-proof electron marksLabel.
【Background technique】
EAS burglary-resisting system is also known as thief-proof (robber) system of electronic goods, is the commodity that current larger retail industry is widely usedOne of safety measure.Today is developed to, because system design difference separates several system equipments：
1, (full name is RFID system：Radio frequency identification system；Low frequency 125KHz, high frequency 13.56MHz, hyperfrequency：860MHz--900MHz)；
2, (full name is AM system：Sound magnetic burglary protection system for commodities frequency：58KHz)；
3, (full name is RF system：Radio frequency system frequency：8.2MHz and it is individual other)；System is divided into detector(Sensor), decoder (Deactivator) and electronic tag (Electronic Label and Tag), this patent be aboutElectronic tag；
RFID system：Electronic tag can play the role of identifying identification, item tracking, information collection as data medium.The RFID system that electronic tag, reader, antenna and application software are constituted directly is connected with corresponding management information system.It is eachPart article can be accurately tracked, can under the acquisition including real time data, safe data access channel, off-line stateTo obtain all product informations etc..It makes an inventory currently, RFID technique has been widely used in such as retail logistics, industry is automaticThe various fields such as change, business automation, the extensive use of RFID tag bring more conveniences to people's lives really.
AM sound magnetic system：Sound fork only just causes to resonate under frequency of oscillation same case.Sound magnetic system (AcustoMagnetic this physical principle) is exactly applied, realizes the operation of almost zero wrong report, the sound magnetic system mark being fixed on commodityWhen label enter the region of system, resonance can be generated, but only receive continuous four resonance signals (every 1/50 second one in receiverIt is secondary) after, just issue alarm.Sound magnetic system includes that vertical system, channel-type system and hidden system do not have to type.
RF radio frequency system：Radio system (Radio Frequency, RF) receives letter as transmitting using radio waveNumber, detection frequency range is 7.x~8.x megahertzs.Radio system great advantage is that system cost is very low, easy for installation.But since its anti-theft tag is ring coil type, so interference of the system vulnerable to some articles, such as cash register electronic product, goldBelong to object etc., causes the wrong report of system or do not report.
Currently there are electronic tag type and behaviour in service it is as follows：
(1) common ultrahigh frequency RFID electronic tag, may be implemented the coding of single-item grade, makes an inventory in automation, is excellent in logisticsGesture is obvious, but sensitive to human body, moisture, metal material, slightly has interference when using in retail shop, can not just play antitheftFunction；
(2) AM sound magnetic cooperation demagnetizer and magnetic induction channel, may be implemented the commodity demagnetization normally settled accounts, improper checkoutKinds of goods by channel alarm realize it is antitheft, because that can not tag number cannot be done article and be made an inventory；
(3) RF cooperates decoding deck and induction channels, and the commodity normally settled accounts decoding, the kinds of goods of improper checkout may be implementedIt is antitheft by the realization of channel alarm, it cannot equally do article and make an inventory；
In conclusion RFID tag is difficult to apply in retail trade need on antitheft product, AM, RF can be antitheft, butThe article that can not be applied to retail makes an inventory and logistics monitoring.
【Utility model content】
The utility model aim is that solving RFID tag is difficult to apply in retail trade need on antitheft product, AM markLabel or RF label can be antitheft, but the article that can not be applied to retail is made an inventory with the deficiency of logistics monitoring and a kind of EAS for providingAnti-theft electronic tag.
The utility model is achieved through the following technical solutions：A kind of EAS anti-theft electronic tag, including shell, AMLabel or RF label, ultra-high frequency RFID label, side is equipped with AM label or RF label in the shell, another in the shellSide is equipped with ultra-high frequency RFID label.
Further, the RFID chip of the ultra-high frequency RFID label avoids the edge 3mm or more of AM label or RF label,And area≤ultra-high frequency RFID label of the position overlapping region of ultra-high frequency RFID label antenna traces and AM label or RF labelThe 10% of the antenna gross area.
Further, the shell includes upper housing, lower case, and the upper housing is fastened in the lower case, describedUpper housing or lower case inner sidewall are equipped with AM label or RF label mounting groove, and the AM label or RF label are embedded in the AM markIn label or RF label mounting groove, the lower case or upper housing inner sidewall are equipped with ultra-high frequency RFID label.
Further, the ultra-high frequency RFID label is divided into left and right two parts, and shape cooperates the shape of lower case or upper housingShape is fitted in lower case or upper housing inner sidewall.
Further, the ultra-high frequency RFID label shape is disk like, including the left dish wing, the right dish wing, RFID chip, connectionAntenna, by connection antenna connection between the left dish wing and the right dish wing, the connection antenna lower part is equipped with RFID chip.
Further, the recessed window of threaded openings is avoided on mirror image, the left dish wing top each other for the left dish wing or the right dish wing,The downward both sides closing waist in left dish wing top extends butterfly shape of tail, closing waist on the right side of the left dish wing after closing waist on the left of the left dish wingExtend to the right afterwards, bent when butterfly tail end downward vertically, extend simultaneously bifurcated again horizontally to the right, wherein one forms typeShape is connect with the right dish wing, and another bifurcated extends horizontally to the right is connected with RFID chip between the right dish wing.
The beneficial effects of the utility model are：
(1) AM label or RF label are combined with ultra-high frequency RFID label, reduce cost, ingenious in design, integrated beautyIt sees；
(2) AM label or RF label are combined with ultra-high frequency RFID label, make full use of AM label or RF label andThe advantages of ultrahigh frequency RFID, the automation that can solve single-item grade product makes an inventory, logistics, and solve the problems, such as it is antitheft, and can be into oneStep expands the use scope and ability of EAS.
