Description

The proposed method and system relates to the field of electronic information systems, in particular to methods and systems that implement information support in remote access networks and aimed at identifying agricultural products that are received for sale.

Currently, the authenticity of agricultural products sold, as a rule, is determined by signs, for example, relevant documents accompanying agricultural products, symbolic markings applied to agricultural products.

The absence of such external signs, as a rule, indicates that agricultural products are classified as counterfeit, counterfeit or unaccounted for. But even the presence of external signs of agricultural products in today's conditions of widespread and affordable use of high technology does not allow us to reliably consider that the agricultural products sold are genuine.

A known method of controlling the authenticity of agro-industrial products, according to which the authenticity of products is determined by the conformity of its external attributes with the marking data established by the manufacturer of this product (GOST 16317-87 "Electrical household refrigeration appliances, general specifications, section 3.27" Marking ", 1987).

The disadvantage of this method is its low efficiency and the complexity of establishing the fact of conformity of external signs with the marking data set by the manufacturer, since the specified correspondence can only be established by specialists as a result of merchandising expertise. Examination takes time and is an expensive service. This approach is unacceptable when conducting sales transactions in relation to agricultural products, which does not come directly from the manufacturer - manufacturer, but through intermediaries.

There are also known methods and systems for authenticating agricultural products (ed. Certificate of the USSR No. 1.832.318; RF patents No. 210689, 2128856, 2132569, 2181503, 2183349, 2199781, 2225032, 2292587, 2439696, 2538311; US patents No. 4641347, 5170044, 5528490, 6005960, 6542645; French patent No. 2731816; Japan patents No. 5616852, 2001344324; EP patents No. 080029, 0773503, 0773505; patents WO No. 93/22745, 97/19821 and others).

Of the known methods closest to the proposed one is the "Method of authenticity and movement of alcoholic beverages" (RF patent No. 2439696, G06K 5/02, 2010), which is selected as a prototype.

The known method is implemented by a reader, radio frequency tag and equipment of the manufacturer.

At the same time, the receiving equipment of the manufacturer is built according to the direct amplification scheme, has low noise immunity, sensitivity and a small range. These shortcomings are eliminated by the construction of the receiving equipment of the manufacturer according to the superheterodyne circuit.

However, in a superheterodyne receiver, the same value of the intermediate frequency ω _pr can be obtained by receiving signals at two frequencies ω ₂ and ω ₃ (Fig. 4), i.e.

ω _ol = ω ₂ -ω _g , ω _ol = ω _g -ω ₃ .

Therefore, if the tuning frequency ω _{2 is} taken as the main receiving channel, then along with it there is also a mirror receiving channel, the frequency ω _{3 of} which is located symmetrically (mirror) with respect to the frequency ω _{2 of the} main receiving channel. Conversion on the mirror channel of the reception occurs with the same conversion coefficient k _CR that the main channel of the reception. Therefore, it most significantly affects the selectivity and noise immunity of a superheterodyne receiver.

In addition to the mirror in the superheterodyne receiver, there are other additional (combination) reception channels.

The frequency of any Raman reception channel is determined by the following expression:

ω _ki = | mω _pr −nω _g |,

where ω _ki is the frequency of the i-th Raman reception channel;

m, n, i are positive integers.

So two frequency channels of reception at m = 1 and n = 2 correspond to frequencies:

ω _k1 = 2ω _g -ω _pr and ω _k2 = 2ω _g + ω _pr

The presence of false signals (interference) received via additional channels leads to a decrease in noise immunity and sensitivity of reception of complex signals with phase shift keying.

An object of the invention is to increase the noise immunity and sensitivity of the reception of complex signals with phase shift keying by suppressing spurious signals (interference) received via additional channels.

The problem is solved in that the method of authenticity and movement of agricultural products in production, which, in accordance with the closest analogue, is that each unit of agricultural products is assigned an identification code that is entered into the manufacturer’s server database, and the authenticity of agricultural products is determined by comparing the identification code of the unit of agricultural production with the code available in the specified database of identification codes, and if the codes match they give a message about the authenticity of this unit of agricultural production, in this case, an RF tag is used as the carrier of identification codes for each unit of agricultural products, during the production of each unit of agricultural products, an RF tag is inserted under the label, or cork, or cover, the reader reads the primary code reader information of the radio-frequency tag and supplement the primary code information of the radio-frequency tag of the manufacturer’s code information and type e agricultural products containing at least information about the type, properties, time of manufacture of agricultural products, its composition, forming the identification code of the unit of agricultural products, and an electronic signature, and then enter the identification code of the unit of agricultural products in the server database are produced when moving agricultural products from the conveyor to the warehouse on the latter, the reader reads the data from the radio frequency tag of each unit of exported agricultural products and a mark is placed in the server database in the warehouse about the movement of this agricultural product, while a piezocrystal with a thin-film aluminum interdigital transducer of surface acoustic waves and a set of reflectors deposited on its surface is used as an RFID tag, the interdigital transducer contains two comb electrode systems, connected by buses connected to a microstrip antenna, also made on the surface of the piezocrystal, form a high-frequency oscillation with pilots at ω ₁ is irradiated they every unit of agricultural products on the conveyor, receiving microstrip antenna is converted into an acoustic wave, ensure its spread over the surface of the piezoelectric crystal and back reflection is converted reflected acoustic wave to complex electromagnetic signal with phase shift keying, the internal structure of which corresponds to the structure vetrechno a pin converter, re-emit it on the air, catch the transmitter-receiver antenna, amplify in amplitude, carry out synchronous detection at a frequency of ω ₁ using a probing high-frequency oscillation at a purity of ω ₁ as a reference voltage, a low-frequency voltage is proportional to the identification code M ₁ (t) of each unit of agricultural products, it is delayed for a time equal to the duration of the identification code M ₁ (t ), summarized with the identification code M ₂ (t) of the manufacturer of agricultural products, containing at least information about the type, properties, time of manufacture of agricultural products, its composition ve, multiply the high-precision oscillation with a frequency of ω ₁ by itself, isolate a high-precision oscillation with a frequency of ω ₂ = 2ω ₁ , manipulate it in phase with the total code M _Σ (t) = M ₁ (t) + M ₂ (t), thereby the most complex signal with phase shift keying at a frequency of ω ₂ , amplify it in power, radiate, receive the manufacturer’s antenna equipment, amplify in amplitude, differs from the closest analogue in that the amplitude-amplified complex signal with phase shift keying is converted in frequency using frequency ω _g heterodyne, which is chosen equal to the frequency ω _{2 of the} received complex signal with phase shift ω _g = ω ₂ , a low-frequency voltage is allocated proportional to the total modulating code M _Σ (t), enter it into the manufacturer’s server database and simultaneously multiplied with the amplitude-amplified complex signal with phase shift key, emit a harmonic voltage and compare it in frequency with the voltage of the local oscillator and if they differ in frequency, then form a control voltage, the amplitude and polarity of which is determined by the degree and side off neniya frequency ω _r of the oscillator carrier frequency ω ₂ of the received complex signal with phase shift keying, they affect the control input of local oscillator automatically seeking equality frequency ω _r = ω _2.

The structural diagram of a reader implementing the proposed method is presented in FIG. 1. A functional diagram of a radio frequency tag on surface acoustic waves is shown in FIG. 2. The block diagram of the receiving equipment of the manufacturer is shown in FIG. 3. A frequency diagram illustrating the formation of additional receive channels is shown in FIG. four.

The reader (reader) contains a serially connected master oscillator 1, a duplexer 2, the input-output of which is connected to the transceiver antenna 3, a high-frequency amplifier 4, a phase detector 5, the second input of which is connected to the output of the master oscillator 1, code comparison unit 7, the second input of which is connected to the output of the database of identification codes 6, key 8, the second input of which is connected to the output of the phase detector 5, the delay line 9, the adder 11, the second input of which is connected to the output of the pseudo-random generator 10 (PsP), phase manipulator 14 and power amplifier 15, the output of which is connected to the second input of duplexer 2. A multiplier 12 is connected to the output of the master oscillator 1, the second input of which is connected to the output of the master oscillator 1, and a narrow-band filter 13, the output of which is connected with the second input of the phase manipulator 14.

The radio-frequency tag is made in the form of a piezocrystal 16 with a thin-film aluminum interdigital transducer (IDT) of surface acoustic waves (SAW) deposited on its surface and a set of 21 reflectors. IDT contains two comb systems of electrodes 18 connected to each other by buses 19 and 20, connected with a microstrip antenna 17.

The output of the low-pass filter 26 is connected to the input of the database 27 of the manufacturer's server. A multiplier 29, a narrow-band filter 30, and a phase detector 31 form a PLL system 28.

The proposed method for controlling the authenticity and movement of agricultural products is implemented as follows.

A feature of the method is that as a carrier of identification codes for each unit of agro-industrial products, an RF tag is used in the form of a piezocrystal 16 with a thin-film aluminum interdigital transducer (HPS) of surface acoustic waves (SAW) and a set of reflectors 21. The HPS contains two comb systems of electrodes 18, which are interconnected by buses 19 and 20, connected with a microstrip antenna 17.

The principle of operation of the interdigital surfactant transducer is based on the fact that the electric fields in space and time created in a piezoelectric crystal by a system of electrodes cause elastic deformations due to the piezoelectric effect, which propagate in the form of a surfactant over the crystal surface.

The basis of the operation of devices on surfactants are three physical processes:

- conversion of the input electrical signal into an acoustic wave;

- propagation of an acoustic wave along the surface of a sound duct;

- reflection and inverse transformation of the surfactant into a coded electrical signal.

For direct and inverse conversion of surfactants, IDTs are used.

The center frequency and bandwidth of the IDT are determined by the pitch of the electrodes and their number. The order of placement of the electrodes carries individual information about the unit of agricultural production. IDT is fabricated by standard photolithography methods and by etching a thin metal film deposited on a piezoelectric crystal. The capabilities of modern photolithography make it possible to create IDTs operating at frequencies up to 3 GHz.

In production, an RFID tag is embedded in the label, or under the cork, or lid of each unit of agricultural products. When passing each unit of agricultural products along the conveyor past a stationary or portable control device, which includes a reader, a high-frequency oscillation is formed by the master oscillator 1.

u ₁ (t) = U ₁ ⋅ Cos (ω ₁ t + ϕ ₁ ), 0≤t≤T ₁ ,

where U ₁ , ω ₁ , ϕ ₁ , T ₁ is the amplitude, carrier frequency, initial phase, and duration of the high-frequency oscillation, which through the duplexer 2 enters the transceiver antenna 3, is radiated by it into the air, and irradiates the nearest radio-frequency tag. A high-frequency harmonic oscillation at a frequency of ω _{1 is} captured by a microstrip antenna 17, the IDT is converted by a frequency tuned to a frequency of ω ₁ into an acoustic wave that propagates along the surface of the piezoelectric crystal 16, is reflected from a set of 21 reflectors, and is again converted into a complex signal with phase shift keying (PSK).

u ₂ (t) = U ₂ ⋅ Cos [ω ₁ t + ϕ _k1 (t) + ϕ ₁ ], 0≤t≤T ₁ ,

where ϕ _k1 (t) = {0, π} is the manipulated component of the phase, which displays the law of phase manipulation in accordance with the modulating code M ₁ (t), which displays the identification code of the unit of agricultural production, and ϕ _k1 (t) = coust at kτ _e <t <(k + 1) τ _e and can change stepwise at t = kτ _e , i.e. at the borders between elementary premises (k = 1, 2, ..., N ₁ -1);

τ _e , N ₁ - the duration and number of chips that make up a signal of duration T ₁ (T ₁ = N ₁ ⋅τ _e ).

Moreover, the internal structure of the formed complex QPSK signal is determined by the IDT topology, has an individual character and contains information about a specific unit of agricultural products (for example, the serial number of agricultural products).

The formed complex PSK signal u ₂ (t) is radiated by the microstrip antenna 17, captured by the transmitter-receiver antenna 3, and fed through the duplexer 2 and high-frequency amplifier 4 to the first (information) input of the phase detector 5. To the second (reference) input of the phase detector 5 as a reference voltage, a high-frequency oscillation u ₁ (t) is supplied from the output of the master oscillator 1. As a result of synchronous detection, a low-frequency voltage is generated at the output of the phase detector 5

u _н1 (t) = U _н1 ⋅ Cosϕ _k1 (t), 0≤t≤T ₁ ,

Where

proportional to the modulating code M ₁ (t).

This voltage is supplied to the first input of the code comparison unit 7, to the second input of which codes are supplied from the output of the database 6 identification codes. Identification codes of all units of agricultural products manufactured are entered into this database. If the codes to be compared are equal, then the block 7 code comparison generates a constant voltage, which is supplied to the control input of the key 8 and open it. In the initial state, key 8 is always closed. In this case, the low-frequency voltage u _n1 (t) from the output of the phase detector 5 through the public key 8 is fed to the input of the delay line 9, where it is delayed for a time τ _s equal to the duration τ _{1 of the} modulating code M ₁ (t) (τ _s = τ ₁ ) , and goes to the first input of the adder 11.

The passage of low-frequency voltage u _n1 (t) through the key 8 indicates the authenticity of the controlled agricultural products.

At the second input of the adder 11, a modeling code M ₂ (t) is supplied from the output of the pseudo-random sequence generator (PSP) of duration τ ₂ . The modulating code M ₂ (t) is the code information about the producer and type of agricultural products, containing at least information about the type, properties, composition and time of manufacture of agricultural products. The output of the adder 11 is formed of the total modulating code

M _Σ (t) = M ₂ (t) + M ₁ (t),

duration τ _Σ = τ ₁ + τ ₂ ,

which goes to the first input of the phase manipulator 14.

The high-frequency oscillation u ₁ (t) from the output of the master oscillator 1 simultaneously arrives at two inputs of the multiplier 12, at the input of which a harmonic voltage is generated

u ₃ (t) = U ₃ ⋅ Cos (ω ₂ t + ϕ ₂ ), 0≤t≤T ₁ ,

ω₂=2ω₁, ω₂=2ω₁, Where

 ω₂= 2ω_one, ω₂= 2ω_one,

which is allocated by a narrow-band filter 13 and fed to the second input of the phase manipulator 14. At the output of the latter, a complex signal with phase manipulation is formed

u ₄ (t) = U ₃ ⋅ Cos [ω ₂ t + ϕ _k2 (t) + ϕ ₂ ], 0≤t≤T ₁ ,

where ϕ _k2 (t) = {0, π} is the manipulated phase component that displays the phase manipulation law in accordance with the total modulating code M _Σ (t), which after amplification in the power amplifier 15 through the duplexer 2 enters the transceiver antenna 3 is radiated by it, captured by the receiving antenna 22 of the equipment of the manufacturer and, through the high-frequency amplifier 23 tuned to the frequency ω ₂ , is fed to the first input of the mixer 25 and multiplier 29. The voltage of the local oscillator 24 is supplied to the second input of the mixer 25

u _g (t) = U _g ⋅ Cos (ω _g t + ϕ _g ).

At the output of the mixer 25, voltages of combination frequencies are generated. Since the frequency ω _{g of the} local oscillator 24 is chosen equal to the frequency ω _{2 of the} received complex signal with phase shift keying (ω _g = ω ₂ ), a low-frequency voltage (zero frequency voltage) is allocated by the low-pass filter 26

u _n2 (t) = U _n2 ⋅ Cosϕ _k2 (t), 0≤t≤T ₁ ,

Where

proportional to the total modulating code M _Σ (t),

which enters the database 27 of the server of the manufacturer and the second input of the multiplier 29.

It should be noted that the choice of the frequency ω _{g of the} local oscillator 24 equal to the frequency ω _{2 of the} received complex PSK signal (ω _g = ω ₂ ) provides a combination of two procedures: the conversion of the received complex PSK signal to zero frequency and the allocation of the low-frequency voltage u _Н2 (t), proportional total modulating code M _Σ (t), i.e. synchronous demodulation of the received complex PSK signal using a local oscillator 24, a mixer 25 and a low-pass filter 26. Such a circuit design allows you to get rid of additional receiving channels and the phenomenon of "reverse work", characteristic of the well-known demodulators of complex PSK signals (Pistolkors A. A., Siforov V. I., Kostas D. F. and Travin G. A.). Since the frequency ω _{2 of the} received complex QPSK signal can vary under the influence of various destabilizing factors, including the Doppler effect, to perform and maintain the equality ω _g = ω ₂ , the PLL system 28 is used, consisting of a multiplier 29, a narrow-band filter 30, and a phase detector 31.

The output of the multiplier 29 produces a harmonic voltage

u ₅ (t) = U ₅ ⋅ Cos (ω ₂ t + ϕ ₂ ), 0≤t≤T ₁ ,

Where

which is compared in frequency with the voltage u _g (t) of the local oscillator 24 in the phase detector 31. If the harmonic voltages u _g (t) and u ₅ (t) differ in frequency, then a control voltage is generated at the output of the phase detector 31, the amplitude and the polarity of which is determined by the magnitude and side of the deviation of the frequency ω _{g of the} local oscillator 24 from the carrier frequency ω _{2 of the} received complex PSK signal u ₄ (t). The control voltage acts on the control input of the local oscillator 24, automatically ensuring the equality ω _g = ω ₂ .

The work of the method described above corresponds to the control of the authenticity and movement of agricultural products in production.

When moving agricultural products from the conveyor to the warehouse on the latter, the reader reads the data from the radio-frequency tag of each unit of agricultural products and enters the data into the server database in the warehouse, and when the agricultural products are taken out of the warehouse, the reader reads the data from the radio-frequency tag of each unit of the exported agricultural products products and enter a mark in the server database in the warehouse on the movement of this agro-industrial products.

All information on agricultural products is automatically entered into the database of the plant’s control device, regardless of whether the manufacturer wants it or not. Tag information is digitally signed. Access to the base of the monitoring device is available only to the appropriate officials of the fiscal authorities.

When agricultural products are removed from the trading floor, they are carried or transported by the cashier or other person past the control device, which includes a reader mounted next to the cash register or built into the counter. In case of violation of the authenticity of information (fake label or data), the monitoring device emits an alarm sound signal.

The control of agricultural products is carried out at all stages of production, marketing and movement:

- at the production stage, a test batch of agro-industrial products is taken and the conformity of the information contained in the radio frequency tag, reporting documents or databases in electronic form is checked;

- at the import stage, the conformity of the information contained in the radio frequency tag with the accompanying documents or databases in electronic form is checked;

- at the stage of moving and storage, the conformity of the information contained in the radio frequency tag with the accompanying and warehouse documents or databases in electronic form is checked:

- at the implementation stage, a control purchase is made and the conformity of the information contained in the radio frequency tag, the relevant documents and agricultural products is checked.

The main characteristics of the system that implements the proposed method include the following:

- average reader transmitter power - not more than 100 mW;

- frequency range 400-420 MHz (900-920 MHz);

- range of action - not less than 50 m;

- the number of code combinations - 2 ³² -2 ¹²⁸ ;

- type of emitted signal - harmonic oscillation, type of response signal - a complex signal with phase shift keying;

- dimensions of the RF tag - 8 × 15 × 5 mm;

- the service life of the RFID tag is at least 20 years;

- power consumed by the RF tag - 0 W.

The proposed method provides increased efficiency and reliability of control over genuine agricultural products and their movement. This is achieved by using radio frequency tags on surface acoustic waves.

The main feature of these labels is the lack of power sources, small size and the use of complex signals with phase shift keying (PSK).

Complex PSK signals have high noise immunity, energy and structural secrecy.

The energy secrecy of these signals is due to their high compressibility in time and spectrum with optimal processing, which reduces the instantaneous radiated power. As a result of this, a complex PSK signal at the receiving point may be masked by noise and interference. Moreover, the energy of a complex PSK signal is by no means small; it is simply distributed in the time-frequency domain so that at each point of this region the signal power is less than the power of noise and interference.

The structural essence of complex PSK signals is caused by a wide variety of their forms and significant ranges of parameter changes, which makes it difficult to optimize or at least quasi-optimal processing of complex PSK signals of an a priori unknown structure in order to increase the sensitivity of the receiver.

Complex QPS signals allow the use of a modern type of selection - structural selection.

Thus, the proposed method and system in comparison with prototypes and other technical solutions of a similar purpose provide increased noise immunity and sensitivity of the reception of complex signals with phase shift keying.

This is achieved by suppressing false signals (interference) received via additional channels, and eliminating the phenomenon of “reverse operation”, which is characteristic of the well-known demodulators of complex PSK signals (Pistolkors A.A., Siforov V.I., Kostas D.F. and Travin G.A.).

The PLL system, which consists of a multiplier, a narrow-band filter, and a phase detector, provides automatic tracking of changes in the carrier frequency ω _{2 of the} received FMN signal, which can occur under the influence of various destabilizing factors, including the Doppler effect, the fulfillment and maintenance of the equality ω _g = ω ₂ .
