Description

Technical field

The technical solution relates to a light-reflective plate with data carrier and registration number of motor vehicles and trailers, which is placed on the external surface or behind the glass of the cabin of motor vehicles and trailers and serves, after placement of a specific registration number, for external identification and registration of road motor vehicles. intended for the transport of persons or property, and / or trailers and special vehicles, and the authenticity of the retro-reflector plate and its registration number used therein, including the verification of the identity, condition and authenticity of motor vehicle and trailer data entered in their chip memory and correspond to their registration data, using external RF readers.

BACKGROUND OF THE INVENTION

There are two common ways to connect a data carrier, e.g. RFID sticker, with vehicle and trailer registration number One uses the location of the data carrier on the vehicle windshield, which is read by a road or handheld reader. The second way is to connect the data carrier to the vehicle by inserting it in its license plate. However, such a solution, in particular in light reflective plates with an aluminum backing light reflective foil, suffers from limited communication transmission, i. j. a small distance due to the significant influence of the metal license plate and its parts, in particular the underlying aluminum light reflection film, on the antenna performance of the data carrier used.

According to WO 2008079902 A1 and / or WO2010051980, and / or EP 1903531 A1, a license plate with a data carrier is known, e.g. an RFID tag that is comprised of a metal license plate with a transverse or longitudinal and transverse groove (slot) with an internal extension and a passive RFID chip disposed in the slot extension, wherein the data carrier comprises a chip and an antenna loop associated with the metal license plate. In the embodiments described herein, a license plate with a data carrier is formed using a license plate or a retro-reflective electromagnetic wave formed thereon as part of a resonator configured to transmit signals processed by the data carrier chip integrated with the license plate. The antenna loop used may alternatively be connected to a metal plate, for example an inductive or conductive connector. In this way, the metal number plate can be configured to function as a resonator providing its increased performance.

The technical drawback of these solutions is that sufficient distance to read the data carrier used is provided only by optimizing the width and length of the cut-out portion of the license plate according to the radio frequency, which increases the slot width and significantly weakens the metal plate with long or longitudinal and transverse grooves. slot) with internal extension and results in normal road traffic, its rapid deformation, degradation of functionality and short lifetime of the license plate. At the same time, such a solution is technically complicated and expensive to cover its transverse or longitudinal and transverse grooves on both sides.

According to JP2008284967, a data carrier, e.g. An RFID tag having a passive RFID chip located in the central part of the license plate and two of its antennas having a cut-out shape mirroring each other in an inverted "T"; j. two mutually inverted grooves extending horizontally from left to right and in the middle to the edges of the table. The data carrier chip and the antenna portion are mounted in the conductive license plate, the data carrier chip being located on its rear side in the cutout portion.

Even in this case, the technical drawback of the described solution is that sufficient reading distance of the used passive data carrier is ensured only by optimizing the width and length of the cut-out part of the license plate according to the radio frequency, which increases the width of the grooves used. they weaken the metal license plate near the center and result in its rapid deformation, degradation of functionality and short life span of the license plate in normal road traffic. Also such a solution is technically complicated and expensive to cover on both sides its transverse or longitudinal and transverse grooves.

According to US2009021379 (A1), a light reflective plate with a data carrier, e.g. an RFID tag, and a motor vehicle registration number using a registration plate to generate a retro-reflective electromagnetic wave as part of a resonator configured to transmit signals processed by the data carrier chip integrated into the registration plate. The light-reflecting plate comprises a metal plate from the underside with an open or closed slot in the metal plate, in which a simple antenna loop with a passive data carrier chip is mounted. To increase efficiency, the antenna loop may be coupled to a metal plate, such as an inductive or conductive coupling, whereby the metal plate may be configured to function as a resonator providing increased performance.

Also in this case, the technical drawback of the described solution is that sufficient distance to read the used passive type of data carrier is provided only by optimized width and length of the

SK50084-2017 U1 of the license plate according to the frequency of the transmission radio wave, which increases the width of the grooves used, which greatly weakens the metal plate in the center and results in rapid deformation, degradation of functionality and short plate life in normal road traffic. Also such a solution is technically complicated and expensive to cover on both sides its transverse or longitudinal and transverse grooves.

From the technical solution CN 200942743 (Y), a light-reflection plate with a data carrier, e.g. the RFID tag, which contains the vehicle information and the license plate. The passive chip data carrier is positioned between the license plate substrate and its light-reflective film.

However, such a technical solution cannot be applied to license plates commonly used in Europe, comprising an aluminum substrate and a light-reflective film formed on an aluminum substrate film. In this case, the data carrier is fully embedded between the aluminum backing material and the aluminum backing in the structure of its light-reflective foil, i. j. in so-called. Faraday cage, the principle of which is generally and commonly used in electrical engineering to prevent propagation and / or as a barrier to electromagnetic waves and electric fields.

According to the published SK PP 83-2012 it is known to ensure identification of vehicle registration numbers by RFID technology such that the vehicle registration plate contains a non-detachably mounted data carrier, e.g. The RFID tag, with a unique serial number, serves for unambiguous electronic identification and at the same time forms a security feature that makes it difficult to falsify the vehicle registration number. According to this solution, a data carrier is pressed into the vehicle registration plate from the inside so that it is not visible from the outside. However, such a solution cannot be applied to license plates commonly used in Europe, comprising an aluminum backing and a light reflecting foil formed on an aluminum backing sheet. In this case, the data carrier is shielded against the front electromagnetic waves by the aluminum backing material of the table and also by the aluminum carrier layer in the structure of its light-reflective foil, making it unreadable from the front by external readers. Therefore, data from its passive chip can only be captured from the other side of the license plate after it has been removed from the vehicle, which is laborious and impractical.

According to SK UV 5435, a registration plate of a motor vehicle and trailer with a radio frequency identification chip is known. The essence of the solution is that a reflective reflective foil at the place of the graphic symbol resp. An active radio frequency chip or passive radio frequency chip placed on the table in a shape copying the shape of the graphic symbol from the registration table.

However, such a technical solution cannot be applied to license plates commonly used in the SR, since they comprise an aluminum substrate and a light-reflective foil formed on an aluminum substrate foil. In such a case, the data carrier, e.g. an RFID tag, fully embedded between the aluminum backing material and the aluminum backing in the structure of its light-reflective foil, i. j. in so-called. Faraday cage, the principle of which is generally and commonly used in electrical engineering to prevent propagation and / or as a barrier to both electromagnetic waves and electric fields.

Another alternative technical solution according to SK UV 5435 is that a passive radiofrequency chip is attached above the graphic symbol on the front side of the reflector plate substrate, which is inseparably connected to the substrate and covered with a top, covering, clear, light-transmissive, light-reflective foil. , or the radio frequency chip is an integral part of the topsheet.

Such a solution does not employ the installation and placement of an antenna which forms a data carrier with the radio-frequency chip and which, with the technical parameters of the upper layer, decides on the functional distance of remote contactless data acquisition from the radio-frequency chip by external readers. Therefore, only the proposed use of a passive radio-frequency chip with data on a light-reflecting plate which is still covered by a top cover layer, i. j. without the use of a data carrier antenna in the light-reflective plate, it does not allow remote contactless reading of data from the radio-frequency chip by conventional external readers without removing the light-reflective plate from the vehicle, making it time-consuming, costly and uncomfortable for the verifier.

The essence of the technical solution

The above-mentioned deficiencies are remedied to a large extent by a light-reflective plate with a data carrier and a registration number of motor vehicles and trailers, consisting of a data carrier consisting of a passive or active memory chip with an electronic circuit and emitting antenna of electromagnetic signals. foil, which may be provided with color graphics, consisting of an aluminum layer provided with a continuous layer of adhesive on one side and a light-reflective layer provided with an outer protective layer on the other side, on which the outer perimeter frame protruding and color code motor vehicles and trailers. The essence of the technical solution is that on or in the light-reflective foil or on the boundary layer there is a data carrier whose passive or active memory chip is an electronic circuit

SK50084-2017 U1 coupled with a transceiver antenna of electromagnetic signals parallel to the metal background of the light reflector plate with data carrier and vehicle registration number.

It is advantageous here that the spacer layer is located in the recess of the metal substrate.

Furthermore, it is advantageous if the memory chip with the electronic circuit connected to the transmitting-receiving antenna and the transmitting-receiving antenna of the electromagnetic signals of the data carrier are mounted in or above the delimiting layer or above or below the outer protective layer of the light-reflective foil.

It is also advantageous if the light reflective foil and the storage medium with the electronic circuit connected to the transceiver antenna and the transceiver antenna of the data carrier electromagnetic signals are mounted below the transparent surface film.

It is likewise advantageous if the light-reflective foil is mounted on the metal substrate only up to the projection of the peripheral frame of the pre-elongated metal substrate, whereby the projection of the peripheral frame of the metal substrate and the light-reflective film can be provided with a common transparent surface film. above the data carrier color graphics of the light-reflective foil at the location of the data carrier.

The light-reflective plate with data carrier and registration number of motor vehicles and trailers according to the present technical solution ensures, without weakening the base by long grooves and recesses and the consequent necessity of their covering, technically simple and comfortable verification of its authenticity in the form of remote contactless data acquisition from radio-frequency frequency chip by conventional external readers with the possibility of using the resonance of its base area when transmitting signals processed by the memory chip of the data carrier, e.g. RFID label, and is technically simple. At the same time, it allows clear visual and electronic identification of motor vehicles and trailers in combination with their assigned registration number and electronic identification code or other information contained and defined in the passive or active radio-frequency chip of the data carrier, thereby significantly reducing, for example. Reflectors with registration number of motor vehicles and trailers. Also, such a reflector plate only slightly influences the designs of the present reflector plate with the registration number of motor vehicles and trailers and satisfies their requirements for use in the operation of road motor vehicles and trailers intended for the transport of persons and / or goods.

EXAMPLES

Examples of a single-row reflector plate with a data carrier and a registration number of motor and trailers according to the present invention are shown in FIG. 1 to FIG. Such light-reflecting plates are composed of a data carrier 1, e.g. RFID tag, with an electronic circuit not shown, and an emitting antenna 2 of electromagnetic signals and a metal substrate 3, for example aluminum, with a light-reflective foil 4 adhered, which is shown with graphics and consisting of an aluminum layer not shown with a continuous adhesive layer on one side; On the light-reflecting plate with the data carrier, the outwardly preformed and colored projection of the peripheral frame 6 as well as the corresponding afanumerics 7 of the registration number of motor vehicles and trailers are preformed and painted on the light-reflective plate 4 and below the light-reflective foil 4. a passive or active data carrier 1 with an electronic circuit connected to a transceiver antenna 2 of the electromagnetic signals of the data carrier 1, which is parallel to the metal substrate 3 world, is mounted by transparent surface foil 8 in or on the spacer layer 5 lo-rebound plate with registration

SK50084-2017 U1 number, for example aluminum. The mounting of the data carrier 1 is formed on a pre-laminated registration number plate consisting of a metal substrate 3 and a laminated light-reflective foil 4 by way of manual or machine application of the data carrier 1 to or on the spacer layer 5 or directly onto the light-reflective The data carrier 1 is preferably mounted behind the left surface of the light-reflective film 4 with the representation of a narrow dark (blue) rectangle with rounded outer corners, in which the stars (yellow or white) are arranged in a contrasting circle, under which it is located. a pair of white or yellow letters SK by applying colors in the structure or on the surface of a light-reflective film meeting the prescribed photometric and colorimetric properties, for example according to STN ISO 7591 Z4.

The production of a light reflector plate with a data carrier and a registration number for motor vehicles and trailers according to the invention starts with the insertion and attachment of the data carrier, e.g. an RFID tag consisting of a passive or active chip with an electronic circuit not shown and an emitting antenna 2 of electromagnetic signals, into or on the spacer layer 5, the substrate of which is then adhered to the indicated position above the outer protective layer 9 of the reflective foil 4. it is already identical to the current production of a light-reflecting plate with registration number of motor vehicles and trailers without data carrier 1, i. j. a light-reflective foil 4 with a fixed data carrier 1, e.g. an RFID tag to which it is adhered, e.g. The transparent surface film 8 is laminated thereafter. Then, on such a plate, looking towards its light-reflecting film 4, the projection of the peripheral frame 6 and the corresponding alphanumeric 7 of the registration number of the respective motor and / or trailer are preformed and suitably colored. Such a table is then mounted in a known manner in the holder of the respective motor and / or trailer and, if necessary, it is verified in a known manner by means of remote contactless reading of data from its radio frequency chip by conventional external readers.

Further examples are two-row light reflectors with a data carrier and a registration number of motor vehicles and trailers according to the present invention, which are shown in FIG. 6 to FIG. 10. Such light-reflecting plates are different from the single-row light-reflecting plates with a data carrier and the registration number of the motor vehicles and trailers shown in FIG. 1 to FIG. 5 only in the use of a data carrier 1, e.g. RFID plate, for a shorter length, for example up to half the width of two-row reflector plates with data carrier and registration number of motor vehicles and trailers. In this case, the data carrier 1 is mounted on its reflective foil 4 behind the left surface, showing a narrow dark (blue) rectangle with a rounded outer corner, in which the stars (yellow or white) are contrasted in a circle under which it is placed a pair of white or yellow pi shifts by applying colors in the structure or on the surface of the light-reflective film 4 meeting the prescribed photometric and colorimetric properties, for example according to STN ISO 7591 Z4. For the reasons given above, its composition, manufacturing and authentication procedure in the form of remote contactless scanning of data from its radio frequency chip by common external readers are identical, therefore they are no longer mentioned in duplicate.

The illustrated and described embodiments of the light-reflective plate with data carrier and registration number of motor and trailers according to the invention are not the only possible examples of this technical solution, since the light-reflective foil 4 can be a one-row and / or two-row light. a reflector plate with a data carrier and a registration number of motor vehicles and trailers mounted on a metal substrate 3 only up to the projection of the peripheral frame 6 of the preformed metal substrate 3, such removal of a portion of the light-reflective foil 4 creates a more powerful resonator a reflector plate with a registration number, which significantly increases the power of the transceiver antenna 2 of the data carrier T Also the shoulder of the data carrier 1 can form an integral part of the light-reflective foil 4, t. j. it is already mounted by its manufacturer not shown in the manner below its outer protective layer 9. Furthermore, a different or a different light-reflecting sheet 4 can be formed on the light-reflecting sheet 4 of the light-reflecting sheet. no graphics and different alphanumerics of the registration number of motor vehicles and trailers or other vehicles. Other partially visually hidden authorization emblems may be formed in the light-reflective film structure 4, or the light-reflective film 4 structure may not have photometric and colorimetric properties according to STN ISO 7591 Z4, or partially visually hidden authorizations may not be formed in the light-reflective film structure 4 emblems of matte square shape with a pair of letters SK in the background color and / or its other security features. Furthermore, the projection of the peripheral frame 6 of the metal substrate 3 and the light-reflective film 4 can be provided with a common transparent surface film 8 or only with the color of the peripheral frame 6 and the metal substrate 3 need not be made exclusively of aluminum but of any metallic material. The transparent surface film 8 can also be provided on the inside above the data carrier 1 with color graphics of the light reflective film 4 from the location of the data carrier 1, which allows the data carrier 1 to be used in any position of the light reflective film 4. manufacturing damage to the memory chip of the data carrier 1 and its electronic circuit (not shown).
