Abstract

The utility model relates to an anti-detachable external powerless electronic label which comprises a chip (1) and a microstrip antenna (3) connected with the chip (1). A metal reflecting layer (2) is arranged between the chip (1) and the microstrip antenna (3) and mounted at the inner side of a base (5) of the electronic label, the chip (1) uses a fragile material as a carrier and is mounted at the outer side of the base (5), and the microstrip antenna (3) is mounted at the inner side of the top of an upper cover (4) which is matched with the base (5). The anti-detachable external powerless electronic label solves the problem that the prior electronic label can not simultaneously have two compatible functions of resisting detachment and adhering to a metal surface, has the two compatible functions, long identification distance and good effect and can be used in the fields such as intelligent traffic management, and the like.

Description

Tamper external hanging type passive electronic label

Technical field:

The utility model relates to a kind of communication and intelligent transportation electronic information application, and concrete is a kind of tamper external hanging type passive electronic label.

Background technology:

The electronic tag of domestic production at present, what have can be affixed on the metal surface, as notification number is that the Chinese utility model patent of CN2606402Y discloses a kind of metal attached type electronic tag that can be affixed on the metal surface, by the ordinary electronic label, and magnetic material layer and the metal film layer be close to mutually form, but do not have the tamper function, security is not enough; The energy tamper that has, as notification number is that the Chinese utility model patent of CN2857109Y discloses a kind of anti-demolition electronic tags, by chip and silver slurry silk-screen circuit are integrated in frangible ceramic substrate inside, and engrave the tamper function that cut is realized electronic tag at the another side of ceramic substrate, but this anti-demolition electronic tags can not be affixed on the metal surface, again because with the carrier of pottery as whole electronic tag, product can be inconvenient to store and transport owing to material brittle.

The utility model content:

Can not have tamper simultaneously concurrently and be affixed on the two kinds of functions in metal surface in order to solve existing electronic tag, the purpose of this utility model is to provide a kind of and has above-mentioned two kinds of functions concurrently, and long, the effective tamper external hanging type passive electronic label of decipherment distance.

The utility model is achieved in that

A kind of tamper external hanging type passive electronic label, comprise chip and the microstrip antenna that is connected with chip, a metallic reflector is arranged in the middle of chip and the microstrip antenna, metallic reflector is installed on the face of base inboard of described electronic tag, chip is carrier with the friable material, and be installed on the face of chassis outer side, microstrip antenna is installed on the face of the loam cake inside top that is complementary with base.

Further scheme is: the distance of described metallic reflector and microstrip antenna is no more than 20mm.

Further scheme is: the distance of described metallic reflector and microstrip antenna is no more than 15mm.

Further scheme is: the match circuit of chip is installed on the described friable material, and chip is by the match circuit acknowledge(ment) signal.

Further scheme is: described friable material is stupalith or glass material.

Further scheme is: described tamper external hanging type passive electronic label by base and adhering object together.

Further scheme is: described chip is the UHF-RFID passive chip.

Further scheme is: what the loam cake of described electronic tag and base adopted is the PVC plastics.

Tamper external hanging type passive electronic label of the present utility model, because chip adopts friable material as carrier, and chip and electronic tag base are bonded on the object together, when attempting to tear open the electronic tag that is bonded on the object, the friable material fragmentation, damaged match circuit, cause communicating interrupt, electronic tag is identified the afunction that reads, simultaneously, because chip and microstrip antenna are separated from one another, only connect by circuit, split when moving at electronic tag, can cause the interruption that is connected between microstrip antenna and the chip, this has improved tamper function of the present utility model again from another point of view.Simultaneously, the utility model innovation ground is provided with a metallic reflector between chip and microstrip antenna, on the one hand, can make the utility model can be attached to the metal surface uses, on the other hand, again because the effect of its reflected signal and energy stack, the distance that makes the identification of chip read increases greatly.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described further.

A kind of tamper external hanging type passive electronic label, comprise chip 1 and the microstrip antenna 3 that is connected with chip 1, in the middle of chip 1 and the microstrip antenna 3 metallic reflector 2 is arranged, metallic reflector 2 is installed on the face of base 5 inboards of described electronic tag, chip is carrier with the friable material, and be installed on the face in base 5 outsides, microstrip antenna 3 is installed in loam cake 4 tops that are complementary with base 5, its chips 1 is the UHF-RFID passive chip, the friable material that adopts can be a stupalith, perhaps glass material etc. is as carrier, metallic reflector 2 is no more than 20mm with the distance of microstrip antenna 3, and better distance is to be controlled in the 15mm.What the loam cake 4 of electronic tag and base 5 adopted is the PVC plastics.

In actual use, tamper external hanging type passive electronic label because chip is installed on the face in base 5 outsides, therefore can be bonded on the object with base 5 by base 5 and adhering object together.When attempting to tear open the electronic tag that is bonded on the object, because friable materials such as pottery that the carrier of chip 1 adopts or glass are broken easily, damaged match circuit, communicating interrupt, electronic tag is identified the afunction that reads, simultaneously, because chip 1 and microstrip antenna 3 are separated from one another, only connect by circuit, split when moving at electronic tag, can cause the interruption that is connected between microstrip antenna 3 and the chip 1, this has improved tamper function of the present utility model again from another point of view.Simultaneously, the utility model innovation ground is provided with a metallic reflector 2 between chip 3 and microstrip antenna 1, and on the one hand, can make the utility model can be attached to the metal surface and use, and can be on other surfaces as surface applications such as glass, plastics; On the other hand, because the effect of its reflected signal and energy stack, the distance that makes the identification of chip read increases greatly, and the decipherment distance maximum in the reality test can reach 15m.

The principle of work of the utility model product is as follows: the read write line of rfid system passes through antenna, the emission modulated RF signals, when tamper external hanging type passive electronic label with carrier such as vehicle, when entering the reach of read write line and antenna, by microstrip antenna 3, receive modulated RF signals; Convert the radio-frequency (RF) energy of modulated RF signals to dc energy through UHF-RFID passive chip 1, be the various circuit supplies in the tamper external hanging type passive electronic label chip 1; The UHF-RFID passive chip 1 of tamper external hanging type passive electronic label demodulates data and clock signal from modulated RF signals, and control store is modulated to answer signal with the related data information (comprising ID number) of its storage; Answer signal returns read write line through microstrip antenna 3; Read write line receives answer signal through antenna, behind the demodulation sign indicating number, gives computing machine; Computing machine therefrom extracts related data information (comprising ID number), be superimposed with time that the place (station number) of RFID application system and " label " pass through etc. simultaneously, pass through communication network, pass to the Center For Information Management of application system, thereby finish the data information exchange between RFID application system and " label ".
