    INDUCTIVE SYSTEM FOR DETECTION AND IDENTIFICATION OF A MEDIA
    CARRIAGE
    Descriptive report
    The present invention is intended for devices to monitor traffic for the purpose of
    register and regulate the traffic using identification in vehicles. 0 technically more prototype similar is the system identification automatic from one
    means of transport consisting of electronic means of identification, installed in a means of transport and electronic means of reading and / or recording of electronic means of identification installed in a means of transport, electronic means of identification and electronic means of reading and / or recording of electronic means of identification are to include an inductive emitter and receiver, and an electronic means of identification has at least one HE emitter, made in such a way as to provide operation at a distance of 10 to 90 cm., and at least at least, a UHF transmitter, made in a way that ensures the operation at a distance of 300 to 1000 cm and an electronic memory (see. US20120056725A1).
    The lack of this system is that, first, the high level of complexity, due to the need to use two communication bands, namely HE and UHF, between electronic means of identification installed in a means of transport and means
    Petition 870160003609, of 02/06/2016, p. 3/43
    2/38 electronics for reading information.
    Second, the use of the UHF band makes it impossible to place the antenna below the surface of a road bed due to the high level of wave extinction. At the same time, the possibility of precipitation (rain, dirt, snow and ice) does not allow the UHF antenna to be located directly on the surface of a road bed, in which case the extinction and misrepresentation of the electromagnetic field orientation diagram the UHF antenna repeatedly reduces the system's range and, consequently, the safety of reading information. The UHF RFID system (transponder, antenna and reader) is functional only if there is radio coverage, but the presence of bulky objects (vehicles, buildings), compatible with the length of a wave, results in or complete loss of communication due to the reflection effect of electromagnetic waves, or in unstable reception due to interference. The possibility of identifying a means of transport requires the construction above the road of supports or structures that can accommodate a reader antenna in order to guarantee the reading of the transponder. However, the interference effects inherent in this frequency range and, consequently, the suspension of radio communication, prevent safe operation even in this case. Furthermore, the assembly of some structure next to a road or above a road ends up
    Petition 870160003609, of 02/06/2016, p. 4/43
    3/38 change the architectural view of the network of streets and roads. Also, due to the effect of interference, the location of the position of a means of transport on the corresponding road is difficult.
    Thirdly, the reader 's HF RFID antenna systems are guaranteeing reading from a common transponder at a distance of 80-90 cm, being characterized as long - range systems. The size of such an antenna is restricted due to the fact that its perimeter must be significantly smaller than the wavelength of the inductive system (usually, in an order) for receiving the system with concentrated parameters. Thus, the dimension of a common range area of a frame antenna that works in the composition of a common reader, which form a magnetic field with a voltage of not less than 150mA / m, to operate with a common transponder, is not greater than the area restricted by dimension 800x600x800 mm with the antenna perimeter corresponding to 1/8 the length of a wave (for example, see FEF Electronic HF Long Range reader ID ISC.LR (Μ) 2500). This range of the magnetic antenna does not allow the identification of an object with high speed, including vehicles equipped with a transponder, and the period required for reading the identification information is longer than the period of stay of the transponder within the range of the frame antenna. However, if
    Petition 870160003609, of 02/06/2016, p. 5/43
    4/38 a frame antenna transversely referring to a road bed, its area of reach, due to the restriction of the perimeter of the magnetic frame, cannot include the entire width of the transport route.
    Fourth, these systems, due to their reduced range, compared to the size of a vehicle, are unable to guarantee safe reading in case of installation lateral to the one above a road, due to the difference in vehicle dimensions that can reach up to several meters. In this case, the installation of some structure next to the road also violates the architectural aspect of the network of streets and roads and increases or reduces road safety.
    Fifth, if an HF antenna is positioned below a road bed, that is, in a conductive medium in the form of an earthed conductor, the erratic capacity of the medium and the current of losses are recorded, which results in misalignment of the contour, that is, the reduction of its quality factor and the alteration of the resonant frequency to such an extent that it makes it impossible to align the system in general, and the system loses its operational capacity.
    The deficiencies mentioned reduce the area of application of the solution in question.
    technically more similar prototype is the registration made in the form of a plate
    Petition 870160003609, of 02/06/2016, p. 6/43
    5/38 dielectric in whose front reflective layer is recorded the information of digits and letters for visual reading, and in the following dielectric layer is located the antenna for reception and emission of the signal with a frequency of 915MHz, equipped with a connection feeder ( see US 5621571, cl. G02B5 / 122).
    This device can even be used to identify radio frequencies in a means of transport.
    The lack of this device is that it is impossible to manufacture the autonomous registration plate, since it only includes an antenna that requires the corresponding connection. Complementary connections complicate the process of mounting the license plate, reduce operational safety and provide loss of signal that excluded the likelihood of operating in a passive regime.
    Another shortcoming of this solution is the need for oscillation of the relatively large emitter power, and the existence of a separate element of the antenna within the registration measures requires the use of high frequency bands, in this case it is 915 MHz, whose property is high extinction value, which, in turn, hinders or even impedes the operation of passive registration in the radio frequency communication part.
    In addition, at high lift frequencies whose wavelength is comparable to the
    Petition 870160003609, of 02/06/2016, p. 7/43
    6/38 dimension of registration, the influence of new reflection and haunt of objects located close to, for example, neighboring means of transport, is very large. The new reflections distort the antenna's orientation diagram, sometimes making it difficult and preventing the possibility of detecting or locating the license plate, which reduces the operational security of said registration in the identification systems of a means of transport.
    The mentioned deficiencies reduce the application area of the device in question.
    technically more similar prototype is the detection unit of a motor vehicle with, installed below ground at the point of passage of a means of transport, an induction loop sensor whose inductive resistance is altered in the case of attachment to a motor vehicle, a fixed frequency generator, a means of comparing signals for forming a control signal, which corresponds to the presence close to a means of transport, and a means of responding to said signal. (US 3651452, cl. G08G1 / 00).
    The solution in question makes it possible to record the fact that a means of transport has passed through the strip next to the induction loop. The deficiencies of the system in question are, first, the impossibility of identifying a means of transport to pass, due to the absence of any means of decoding a signal; second, the low level of detection security
    Petition 870160003609, of 02/06/2016, p. 8/43
    7/38 correct means of transport, due to the fact that two moving vehicles can be identified as a single means of transport, although a long vehicle passing on the neighboring road may be detected incorrectly. The shortcomings of this solution, also, are the high probability of not detecting a means of transport with small measures and the high possibility of incorrect activation in the event of a sudden change in time. In addition, the induction loop of the said solution does not provide the means for reducing the mechanical influence produced by means of transport to pass, which results in rapid wear and subsequent failure of the induction loop, which reflects the operational safety of the unit. The deficiencies mentioned reduce the possibility of applying the system in question.
    objective of the invention is to widen the application area. The technical result is the simplification of the system to a single strip, avoiding the construction of a structure above or beside the bed to fix antennas due to the probability of operating with a magnetic frame located above the bed, in addition to ensuring safe and protected operation of the system including the movement of means of transport with a high speed.
    This technical result is achieved by the fact that in the inductive system of detection and identification of a means of transport that includes

    Petition 870160003609, of 02/06/2016, p. 20/43
    19/38 bit and a reader for reading information from the memory of an electronic means of identification of a means of transport. The electronic means of identification of a means of transport is combined in a constructive way with the registration of a means of transport and represents an inductive sign of a means of transport located at the point for the placement of a common sign of a means of transport.
    The inductive license plate has visual information placed on its front part, which guarantees the normal visual reading of the identification information.
    reader is equipped with a magnetic frame, mounted below a road bed at a depth of less than 1 m, guaranteeing the possibility of reading information in the space above the road equal to the width of the road strip. At the inputs of the magnetic frame, the alternating signal is supplied from the corresponding generator with power from 1W to 20W, which ensures the formation of an κοτορΕίΜ alternating magnetic field around the frame, which presents the operational area of the magnetic frame or the area of detection and identification of a means of transport, with boundaries defined by imagined surface around the magnetic frame, where the voltage value of the magnetic field is not less than 10 MmA / m, and where the
    Petition 870160003609, of 02/06/2016, p. 21/43
    20/38 possibility of reading the information from the memory of an inductive license plate of a means of transport passing through the operational area of the magnetic frame of the reader at a speed of up to 250 km / h.
    The range of the magnetic frame, if not covered by the bed layer in a direction perpendicular to the surface of the magnetic frame, is not less than 2.2 m. For magnetic framing installed below a road bed, the vertical range is not less than Im with respect to the road surface. The summary distance of a magnetic frame in the event of a penetration of up to 1 m and operating in conjunction with an inductive license plate is not less than 2 m from the surface of the frame, which defines the detection and identification system of a means of transport as a long distance system.
    The reading of information from the memory of an inductive registration of a means of transport is done under the ISO-15693-3 standard and compatible, in a discreet way by separate shipments. Thus, the minimum reading period per reader of a discreet shipment, formed by electronic means of identification, and
    the period minimum for identification of one middle in transport correspond at the speed of one middle in transport up to 250 km / h and is less than 25 ms. They may be read several, fur any less
    Petition 870160003609, of 02/06/2016, p. 22/43
    21/38 four, inductive license plates for means of transport that are within the operational area of a magnetic frame.
    The reader is connected to a remote computer, which is used as a server, and the connection guarantees a data transmission speed of not less than 19.2 kbit / s, where the communication itself is made through a non-interface. bottom of RS232.
    The computer activates the means of detecting and processing data received from an identified means of transport in order to control traffic and observe the rules of the highway code.
    The remote computer and / or the reader are equipped with a power supply.
    The readers with magnetic frames are made in the form of units of the same type, installed in different sections of a road, and the computer is made in a way that allows it to be connected with a single or several units concerned or with all the readers simultaneously .
    The operation of an inductive system for the detection and identification of a means of transport is as follows.
    A means of transport, equipped with an inductive license plate with electronic means of identifying a means of transport, with resonator
    Petition 870160003609, of 02/06/2016, p. 23/43
    22/38 passive formed by a frame of several turns and microchip with NVRAM, in addition it passes a section of road where below the bed is placed a magnetic frame connected with a corresponding reader that ensures the formation around the magnetic frame of a field alternating magnetic with HF frequency range that is of 3 to 30 MHz. The formed magnetic field is external referring to the passive resonator installed in the means of transport.
    With the installation of the magnetic framework below the road bed, the influence of the earth is considered, which is reinforced with an increase in the size of the antenna that corresponds to the width of the road, which in some cases can reach 3.75 m.
    Deepening of the magnetic frame is necessary in order to guarantee the safe movement of vehicles with high speed. Thus, the magnetic frame must be buried at a depth not less than the asphalt layer, which is around 20 cm, and, otherwise, the bed may be damaged at the installation point of the antenna.
    The use of a system of detection and identification of a means of transport composed of several magnetic frames installed in different sections of several roads, makes it possible to register the fact of the presence of vehicles associated with a certain point
    Petition 870160003609, of 02/06/2016, p. 24/43
    Geographic 23/38. The registration of the presence of a means of transport within a given section makes it possible to locate a means of transport within a moment of time, with accurate measurement of the location and time, determined, correspondingly, by the size of the operational area of a magnetic frame and the identification time (up to 2 m and 25 ms with a maximum speed of 250 km / h). In this case, the possibility of collecting and storing data on fixing a means of transport within a given stretch of road, in addition to analyzing the data in question for a period of time, allows defining the direction of movement of a given means. carriage. In addition, the calculation of time for a means of transport to pass between two points on a road with magnetic frames installed, ensures the possibility of calculating the speed of a means of transport if the distance between both connected points is known.
    Due to the defined ratio of the perimeter of the magnetic frame to the length of 1/5 of 1/2, the perimeter of the magnetic frame is much larger, compared to the length of a common system, which allows the magnetic field to extend over the entire width. At the same time, the framing of several turns, made along the perimeter of the license plate, whose dimension is much larger than the size of a common transponder, thus allowing to obtain the largest size of a
    Petition 870160003609, of 02/06/2016, p. 25/43
    24/38 resonator and the maximum sensitivity of a means of identification of a means of transport, which more than in an order surpasses the sensitivity of a common system, which, in turn, guarantees the long range of an inductive system of the detection and identification of a means of transport.
    If an inductive registration of a means of transport enters the operating area of a magnetic frame, where the voltage value of the magnetic field is more than 10 mA / m, which is sufficient to supply the passive resonator microchip, The microchip forms a modeled signal, which interacts with the current oscillation of the passive resonator, which in turn alters the magnetic field of the magnetic frame. The modulated signal is formed by a microchip according to the data in the NVRAM memory. In this way, the resulting magnetic field is an oscillation with discrete encoded sends, which in turn include the identifying information of a means of transport.
    The magnetic field altered with the response signal is transformed by the magnetic frame into an electrical oscillation transferred to the reader input for demodulation. As a result of demodulation and decoding of the reader input signal, a means of transport is detected and identification information about means of transport is issued. The information obtained by means of signals transmitted through
    Petition 870160003609, of 02/06/2016, p. 26/43

    The detection of a means of transport can also be done by changing a parameter of an alternating magnetic field, caused by the presence of a means of transport passing by.
    In case of entry of several means of transport with their inductive license plates to the operational area of a reader, whose resonators form the corresponding modular signals differentiated by law through which the reference resonant frequency is modulated. In this case, the reader determines the fact of signal multiplication and ensures the formation of a command signal of the same resonant frequency, which through the demodulator of the integrated circuit produces an effect, by microchip processor, on the formation of a modulated signal, as a result In addition, signals formed in distinct resonators are being distributed within ISO 15693, 1800-3 or compatible anti-collision protocols, for example, in time, ensuring an acceptable signal / noise correlation in order to ensure the safe reading of all resonators that are within a reader's operational area.
    To use the system to regulate access to a closed territory, for example, a car park, the reader with magnetic framing is installed at the entrance and exit of the territory,
    Petition 870160003609, of 02/06/2016, p. 27/43
    26/38 even outside the car park where the width of the passageway is 2.5 m to 3 m. However, in this case, through the output signal from a reader of the inductive system for the detection and identification of a means of transport, a barrier or other fence is controlled.
    When using the means of detection and identification of a means of transport within the traffic control system, when necessary, it is completed by means of optical recognition of a license plate of a passing vehicle. The operation of an inductive reader is synchronized with the operation of a photo / video camera equipped with an image recognition means. The fingers obtained from the inductive reading system and the visual recognition system are checked regarding the correspondence of the visual information of an inductive license plate with the identification information stored in the microchip of this inductive license plate.
    inductive system for the detection and identification of a means of transport is a single-track system that works in the low frequency range HF, the fact that allows to place the magnetic frame below the roadbed, thus avoiding the assembly of a structure beside or above the road. At the same time, the range of a magnetic frame is sufficient for the safe detection and identification of a medium

    27/38 high speed transport. In reality, the inductive system of detection and identification of a means of transport is a long-range HF system.
    inductive system for the detection and identification of a means of transport can be carried out using elements, common radio components, using a wired or wireless communication line. The reader can be made on the basis of general modules manufactured in series, for example, the HF Long Range reader ID ISC.LR (Μ) 2500 from FEIG Electronic.
    In this way, the inductive system of detection and identification of a means of transport has a wide application area, being simple and of a single strip, thus avoiding the construction of a structure for locating antennas next to or above the bed of a road, due to the possibility of operating from a magnetic frame placed below the bed, which ensures efficient and safe operation in the event of high-speed traffic.
    The inductive registration of a means of transport is made in the form of a rectangular plate of a dielectric material, being the support structure and with the same dimension as the dimension of a common license plate, with consolidations and attributes of a state license plate. On the reflective front of the plate is the information of letters and digits for visual reading. Inside the plate there is a frame of several
    Petition 870160003609, of 02/06/2016, p. 29/43
    28/38 turns, made along its perimeter with a gap referring to the edge, whose connection with also installed here an integrated circuit - the microchip - is made in a transforming or galvanic way. The framing of several turns together with the integrated circuit form the resonator of alternating magnetic oscillations in the HF band, that is, with the resonant frequency of 3 to 30 MHz. The resonator is an energy accumulator that ensures power supply to the integrated circuit, which , with sufficient energy accumulation it is activated and ensures the modulation of the frequency of magnetic oscillations of the resonator. In this case, the voltage of the lower magnetic field, with which the electric current, induced by the external field in the resonator, reaches the point of being sufficient to supply the microchip, and is not less than 10 mA / m.
    The microchip, which drives the processor, is equipped with an NVRAM module with a capacity of not less than 64 bit to store the means of transport identification data, and operates with a harmonic oscillation modulator of the resonator with the corresponding modulated signal range. at the data transmission speed not less than 1 kbit / s. In addition, the microchip ensures the function of a demodulator of the command signal of the external magnetic field with the possibility of carrying out anti-collision protocols ISO 15693, 18003 and compatible in case of operation of multiple inductive license plates and close to each other.

    of a means of transport is as follows.
    An inductive license plate is installed on the bumper of a means of transport, made of a dielectric material, and, if there is a reverse side of the inductive license plate of a layer of magnetic material, the inductive license plate can be installed on a surface metallic.
    The consolidation of an inductive license plate to a means of transport is done by a common means designed to consolidate a license plate, and does not need a connection to a supply current.
    Certain sections of a road are equipped with magnetic field sources, which emit HF oscillations. If an inductive registration of a means of transport enters the alternating magnetic field, its resonator transforms the energy of the magnetic field into current
    Petition 870160003609, of 02/06/2016, p. 31/43
    30/38 electric.
    Due to the positioning of a framework of several turns along the perimeter, the resonator's property is that its area is greater than
    area one common transponder, thus minimizing the value limit of field voltage alternating magnetic for drive of a microchip. When the voltage value of field
    magnetic energy reaches not less than 10 mA / m, the accumulated energy becomes sufficient to activate and operate the microchip, which ensures the alteration of resonator parameters - modulation, the result of which is the formation of a modulated signal, and the modulation procedure is defined by data stored in the NVRAM of the integrated circuit with information identifying a means of transport. In this way, the modulated signal corresponds precisely to the identification data of a means of transport.
    As a result of the microchip's action, the amplitude, frequency or phase modulation (manipulation) of the resonator oscillations is made. The spectrum of a modulated signal corresponds to the data transmission speed of not less than 1 kbit / s. In this way, the signal is formed in the resonator with a code word, with data, which match the identification data of a means of transport.
    The current that passes around the
    Petition 870160003609, of 02/06/2016, p. 32/43
    31/38 resonator and changes with time forms a corresponding magnetic field that produces an effect on the external alternating magnetic field, which excites the contour of the resonator. The purpose of the alternating magnetic field is the following demodulation by means installed at the points of location of the means for forming an external magnetic field.
    An inductive license plate can be installed on several transport vehicles, in this case the NVRAM memory of each inductive license plate will contain the identification data of only a certain means of transport. In case of the entry of several means of transport with inductive registrations to the operational area of a source of the external magnetic field, their resonators will form the modulated signals distinguished by the reference resonant frequency modulation procedure. In this case, the source of the external magnetic field forms a control signal of the same resonant frequency, demodulated by microchip and which affects the formation of the signal modulated by microchip, being that the signals formed in several resonators are distributed based on anti- collision ISO 15693, 1800-3 or compatible, for example, in time, ensuring the acceptable signal / noise correlation in order to guarantee the safe demodulation of all resonators that are within the operational area of an external magnetic field.

The orientation of the magnetic frame is made so that the longest side of the rectangle is located transversely to the

    33/38 road, the frame is inside a dielectric enclosure made in the form of a parallelepiped with a height of 50 to 200 mm and is installed under a layer of asphalt at a depth of up to 1000 mm, thus the dielectric layer of the enclosure between the framing and the environment is 50 to 200mm. The signal formation and treatment unit ensures the modulation and demodulation, coding and decoding of a signal.
    The dielectric permeability of the dielectric envelope is 1 to 5, when the tangent of the dielectric loss angle is not more than 10-2 -10-3;
    Magnetic framing is made of a metallic tape with a thickness of not less than 0.1 mm or of a metallic tube of the round cut or rectangle is connected to the unit of formation and treatment of a signal through a command and power cable.
    The oscillating contour of the inductive reader is made in a self-adjusting way, or with the contour adjustment in manual or automatic regime.
    The signal formation and processing unit ensures the function of checking received data.
    The enclosure of the magnetic frame is made resistant to vibration, precipitation, aggressive liquids and media, mixtures of sand and salt, gasoline, fungi and has thermo-resistant qualities during laying asphalt, not

    34/38 less than 1700C, and is pressure resistant to wheels not less than 10 tons.
    The signal training and processing unit is connected to a computer, which is used as a server to collect and analyze the data necessary to manage road traffic.
    The inductive reader works as follows.
    In the signal formation and treatment unit, the signal is formed with frequency FH, that is, from 3 to 30MHz, transmitted to the input of the combination unit connected with the rectangle frame installed inside a dielectric enclosure at a depth of 200 mm to 1000 mm below a road bed.
    The combining unit ensures remote alignment, by means of a remote control, of the contour of the magnetic frame by adjusting the resonant frequency of the contour formed by the magnetic frame.
    As a result of the passage of the alternating electric current in the frame, an alternating magnetic field with corresponding HF frequency is created around it, which forms the operational area of the frame. The boundaries of the operational area are defined by an imagined surface around the magnetic frame, where the field voltage value
    Petition 870160003609, of 02/06/2016, p. 36/43
    35/38 magnetic is not less than 10 wmA / m, which is sufficient for the operation of the inductive license plate at a distance of not less than 1 m relative to the surface of a road. At the same time, the size of the operating area depends on the framing size, the placement depth, the definition of the resonant frequency of the framing contour and the output signal strength of the signal forming and processing unit.
    The property of the magnetic framing is that its area is much larger compared to the length of the wave, thus ensuring the possibility of covering the entire width of a roadway. The operating area of the magnetic framing with sides of 2000x500 mm, if positioned below the road bed with a width of 3200 mm, is limited by a space not less than 3200x600x1000 mm above the surface of a road.
    An inductive license plate, installed in a means of transport, entering the operational area of a magnetic frame, is excited by its magnetic field and forms a response, which alters the magnetic field formed through the frame, and which becomes a signal electric, which, in turn, is read by a reader - decoder and is decoded to obtain the identification data of a certain means of transport and its transmission to the remote computer.
    The inductive reader due to its
    Petition 870160003609, of 02/06/2016, p. 37/43
    36/38 structure can be used in inductive detection and identification systems for a means of transport in the long range HF range.
    The magnetic framing is made of a tape or metal tube, the width of the conductor is from 48 to 102 mm. The thickness of the conductor is 0.1 to 1 mm. In this case, the sides of the rectangle, formed by framing, have a ratio of 1x3 to 1x8, when the perimeter of the framing is in the range of 1/5 to 1/2 of the wavelength. The typical dimension of a frame made of metallic tape is 500x2000 mm, with width of the tape is 50mm and the thickness is 0.5mm, presenting the shape of a parallelepiped with dielectric enclosure with the following size: 2500 x 500 x 200 mm (length x width x height).
    The enclosure of the magnetic frame forms between the frame and the conductive bed, a dielectric layer is not less than 50 mm with the dielectric permeability of the dielectric enclosure is 1 to 5, when the tangent of the dielectric loss angle is not more than 10 -2 -10-3. The thickness of the enclosure is 50 ... 200 mm, which makes it possible to reduce the influence of the medium to the quality and resonant frequency of the oscillating contour created by framing. The weight of the wrapper is not more than 50 kg.
    The enclosure protects the frame and the combination unit of external actions, especially
    Petition 870160003609, of 02/06/2016, p. 38/43
    37/38 mechanics, in case of positioning the frame below the asphalt, and it will suffer the significant pressure created by vehicles weighing up to 10 tons for axle.
    In addition, the casing guarantees protection against the ingress of moisture, the thermal influence of -60 to 2000C and the action of aggressive substances, such as gasoline, etc.
    The combining unit provides the possibility of defining the framing contour at a distance and is located, together with the framing within the dielectric envelope, below the road bed, whose electro-physical properties (magnetic permeability, dielectric permeability, conduction) can be distinct. In order to correct the interference caused by the bed, the combination unit is made with the possibility of automatic distance adjustment by self-diagnosis of the system, determination of the standing wave ratio at resonant frequency and alignment of the contour parameters, or in manual mode, responding to an operator command from the control panel or the remote computer.
    The inductive reader is made with a contour of the self-adjusting magnetic frame, and self-adjustment consists of automatic mediation of the relationship of standing waves and the alignment of
    Petition 870160003609, of 02/06/2016, p. 39/43
    38/38 parameters of the oscillatory contour of the magnetic frame in order to minimize the size to be measured.
    inductive reader can be made of common materials, elements and general radio components 5 using sheet metal or profiled treatment. The signal formation and treatment unit can be made based on standardized modules, manufactured in series, for example, the HF Long Range reader ID
    ISC.LR (Μ) 2500 from FEIG Electronic.
    In this way, the inductive reader has a wide area of application due to the possibility of identifying means of transport to pass and the improved functioning of long-range inductive systems.
