Abstract
The utility model discloses a long-distance passive electronic label capable of being attached to the inner side of a car windshield and provided with a ceramic substrate. The long-distance passive electronic label comprises a packaging box (1) and a substrate (2), wherein the packaging box (1) is attached to the inner side of the car windshield, the substrate (2) is packaged in the packaging box (2) and integrated with an RFID (radio frequency identification device) chip (3), a microstrip antenna A (4), a microstrip antenna B (5), a matching circuit A (6), a matching circuit B (7), a transition line A (8) and a transition line B (9). The long-distance passive electronic label has the beneficial effects that the fragile ceramic substrate is used and can be damaged when the label is removed so as to lead the label to have anti-removal property, an unchangeable and unique identification address number and a user and encryption data information block existing in the label ensure that the label can not be duplicated, namely having a unique correspondence relation with a vehicle. The label further has the advantages of long identification distance, small volume and the like.
Description
Technical field
The utility model relates to a kind of remote passive electronic label of ceramic substrate that is affixed on the windshield inboard.
Background technology
Electronic tag claims radio-frequency (RF) tag, transponder or data carrier again, cooperates with reader, and utilization REID (RFID) can play effects such as sign identification, item tracking, information acquisition.Abroad, electronic tag is used in extensive fields.
The utilization of present electronic tag at home more and more widely, as be installed on the automobile, be used for highway charge automatically, traffic administration, automobile burglar etc., but the electronic tag of domestic production, have and to be affixed on windshield inboard and decipherment distance electronic tag far away, but not tamper can not be guaranteed the unique corresponding relation with vehicle.
The utility model content
Utility model purpose of the present utility model is to solve the deficiencies in the prior art, provides that a kind of decipherment distance is far away, the remote passive electronic label of ceramic substrate of the be affixed on windshield inboard of tamper.
Utility model purpose of the present utility model is achieved through the following technical solutions: the remote passive electronic label of ceramic substrate that can be affixed on the windshield inboard, it comprises packing box and substrate, described packing box is attached to the windshield inboard, substrate package is in packing box, be integrated with the RFID chip on the substrate, microstrip antenna A, microstrip antenna, match circuit A, match circuit B, transition line A and transition line B, microstrip antenna A is connected on the pin of RFID chip by transition line A and match circuit A successively, microstrip antenna B is connected on another pin of RFID chip by transition line B and match circuit B successively, also is provided with data memory module and encrypting module in the RFID chip.
Substrate described in the utility model is a ceramic substrate; The all rectangular sheet of microstrip antenna A and microstrip antenna B is provided with four spaces longitudinally in the plane of microstrip antenna A, the length of microstrip antenna A is longer than the length of microstrip antenna B; Match circuit A and match circuit B are the circuit of wire, and this wire circuit comprises the projection of two rectangles, and two rectangular protrusions connect by a U type groove; Transition line A and transition line B are the mountain font.
The beneficial effects of the utility model are: use frangible ceramic substrate, when being disassembled, can be damaged, make this label have tamper, have in the label chip can not revise, identification address (ID) that the whole world is unique number and user and ciphered data information piece, guaranteed that this label is not reproducible, promptly with vehicle unique corresponding relation is arranged, this label also has advantages such as decipherment distance is far away, volume is little.
Description of drawings
Fig. 1 is a cut-open view of the present utility model;
Fig. 2 is on-chip circuit structure diagram;
Among the figure, 1-packing box, 2-substrate, 3-RFID chip, 4-microstrip antenna A, 5-microstrip antenna B, 6-match circuit A, 7-match circuit B, 8-transition line A, 9-transition line B.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing: as Fig. 1, shown in Figure 2, can be affixed on the remote passive electronic label of ceramic substrate of windshield inboard, it comprises packing box 1 and substrate 2, described packing box 1 is attached to the windshield inboard, substrate 2 is encapsulated in the packing box 1, be integrated with RFID chip 3 on the substrate 2, microstrip antenna A4, microstrip antenna B5, match circuit A6, match circuit B7, transition line A8 and transition line B9, microstrip antenna A4 is connected on the pin of RFID chip 3 by transition line A8 and match circuit A6 successively, microstrip antenna B5 is connected on another pin of RFID chip 3 by transition line B9 and match circuit B7 successively, is provided with data memory module and encrypting module in the RFID chip 3.
With the identification address that can not change, the whole world is unique (ID) number, encrypting module then is used for the data in the data memory module are encrypted in the data memory module in the RFID chip 3 of the present utility model.
The utility model volume is less, and volume (length * wide * height) is not more than 85 * 54 * 1.5mm.
Principle of work of the present utility model is: the read write line of rfid system is launched modulated RF signals through antenna; When this electronic tag enters the reach of the read write line of rfid system and antenna thereof with carrier, receive modulated RF signals by microstrip antenna, RFID chip 3 converts the radio-frequency (RF) energy of the modulated RF signals that receives to dc energy, be the circuit supply in the RFID chip 3, RFID chip 3 demodulates data and clock signal from modulated RF signals, and the control data memory module is passed to the related data information (comprising ID number) of its storage the answer signal of modulators modulate electronic tag passback; Electronic tag is transferred to read write line by microstrip antenna with answer signal; Read write line receives answer signal through antenna, behind the demodulation sign indicating number, give computing machine, computing machine therefrom extracts related data information (comprising ID number), add the place of RFID application system and time that label passes through etc. simultaneously, pass to the Center For Information Management of application system by communication network, finished the data information exchange between RFID application system and the label like this.
