Compared with the prior art, the metal anti-dismantling electronic tag utilizes the metallic properties of the license plate and a vehicle body, data is safely and reliably read, the lower shell and the upper shell of the electronic tag are welded into a whole by ultrasonic wave, the anti-dismantling lock is installed independently, and the electronic tag is arranged on the clamping hook of the anti-dismantling lock, so that when the installed electronic tag is pulled by external force, the electronic tag of the ceramic substrate with a notch groove at the back surface is pulled to be broken and is damaged, thus ensuring data safety.
Description
Technical field
The utility model relates to a kind of radio frequency identification equipment, particularly a kind of car plate electronic tag that is applicable to that microwave signal receives and launches in 902MHz～928MHz frequency range.
Background technology
The radio frequency discrimination RFID technology is because to have a reading/writing distance far away, and memory space is big, can be real-time, and the advantage of all weather operations is widely used in logistics, warehousing management, various fields such as asset management.In radio frequency identification equipment, electronic tag is as data carrier, and directly being linked to each other with label antenna by label chip constitutes, and the label antenna performance has very significant effects to radio-frequency (RF) identification.Rfid system is applied in the non-parking charge, because the data in the electronic label chip relate to the amount of money that road and bridge pay dues, so it is stolen in order to prevent the data in the car plate electronic tag, just need a car plate metal anti-demolition electronic tags of design, this has higher requirement to the design of car plate electronic tag, and motor vehicle is mobile strong simultaneously, to the tamper of electronic tag, antitheft, also should take into full account.
Summary of the invention
The purpose of this utility model provides a kind of car plate metal anti-demolition electronic tags of uhf band, and the technical matters that solve is the influence that overcomes the metal pair electronic tag, tamper.
The utility model is by the following technical solutions: a kind of car plate metal anti-demolition electronic tags of uhf band, have antenna and label chip, described antenna adopts folded dipole, described antenna and label chip are arranged on the ceramic substrate, ceramic substrate is fixedly installed on the lower casing, adopt the grab of tamper lock to block simultaneously, be separately fixed on the automobile license plate with lower casing after an end of tamper lock passes lower casing, upper casing is fastened on the lower casing.
Label antenna of the present utility model is printed on the ceramic substrate of thickness less than 1mm, is carved with two grooves of symmetry at the back side of ceramic substrate, at the two ends of label chip.
Label chip of the present utility model adopts Type of Welding to link to each other with label antenna.
One end and the lower casing of tamper lock of the present utility model adopt double faced adhesive tape to be fixed on the automobile license plate respectively.
Lower casing of the present utility model is provided with the fixedly positioning pillars of ceramic substrate, ceramic substrate and lower casing is connected to form be integral body.
Tamper of the present utility model is locked waterproof washer is housed.
Integral body of the present utility model is connected by ultrasonic soldering with upper casing.
The frequency of operation of label antenna of the present utility model is 902MHz～928MHz.
The utility model compared with prior art, utilized the metallicity of car plate and car body itself, label antenna adopts the form of amounting to, the size of label antenna is had significantly dwindles, and still can be safely, reading of data reliably, the lower casing of electronic tag and upper casing are one by ultrasonic soldering, install and the tamper lock is independent, and electronic tag is mounted on the grab of tamper lock, when the electronic tag of installing is drawn by external force, the ceramic substrate electronic tag of back side cutting is broken, and destroys electronic tag, thereby has guaranteed safety of data.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.The car plate metal anti-demolition electronic tags of uhf band of the present utility model is made up of label lower casing 3, tamper lock 1, waterproof washer 2, label antenna 6, label chip 7 and upper casing 13.Wherein tamper lock 1, waterproof washer 2, label antenna 6, label chip 7 are arranged between lower casing 3 and the upper casing 13, and lower casing 3 is fixedly installed on the motor vehicle, and upper casing 13 is fastened on the lower casing 3.As shown in Figure 1, have on the tamper lock 1 of grab waterproof washer 2 is housed, tamper lock 1 passes lower casing 3, be installed on the car plate by double faced adhesive tape with waterproof washer 2, the base two ends are semi-circular, and waterproof washer 2 is of a size of circle, lower casing 3 is provided with positioning pillars 4,5, be used for fixing ceramic substrate 8, the grab of tamper lock 1 blocks ceramic substrate 8, and ceramic substrate 8 is provided with label chip 7 and antenna 6.
As shown in Figure 2, passive electronic label is made up of label antenna 6 and label chip 7.Label antenna 6 is made of folded dipole, and the width 0.8mm of oscillator itself amounts to segment conductor width 0.5mm, and the frequency of operation of label antenna 6 is 902MHz～928MHz.Label chip 7 adopts Type of Welding to link to each other with label antenna 6.Label antenna 6 is printed on the ceramic substrate 8 of thickness less than 1mm.Be carved with two grooves 11 of symmetry at the back side of ceramic substrate 8, in two end slot positions 9,10 of label chip 7.Because groove 11 is engraved on the back side of ceramic substrate 8, do not influence the antenna performance of electronic tag, when electronic tag is installed on the car plate, utilizes the metallicity of car plate and car body to realize the performance of metal electronic tag, and do not need like this other additional metal reflecting plate of electronic tag.
As shown in Figure 3, ceramic substrate 8 is installed on the positioning pillars 4,5 of label lower casing 3 by the grab of positioning pillars 4,5 with tamper lock 1, constitutes whole 12.The feeding point of label chip 7 departs from the tamper lock, and electronic tag faces up.
As shown in Figure 4, be provided with at the two ends of upper casing 13 pilot hole 14,15 be used for a car plate electronic tag by screw retention on car plate, whole 12 with upper casing 14 by ultrasound wave in the welding of the surface of contact place of lower casing 3 and upper casing 13.Post double faced adhesive tape in lower casing 3 bottom surfaces, another double faced adhesive tape is posted on the surface of tamper lock 1, and lower casing 3 and tamper lock 1 are pasted on the car plate.Because the tamper lock is independently to be pasted on the car plate; grab blocks ceramic substrate all the time; like this; when car plate electronic tag integral body is drawn by external force; the car plate electronic tag will be broken the ceramic substrate that groove is carved with at the back side under the acting in conjunction of integral body 12 and positioning pillars 4,5; destroy antenna, thereby reach the purpose of protected data.
