The device works as follows.

When identifying moving objects, the device can be in two modes; adaptation and recognition of objects.

The device is switched to the adaptation mode by the device turn on signal and the pulses of the beginning of the moving object, coming from the sensor 18.

In the adaptation mode, the counter-register 11 is in the pulse counting mode, arriving at its input from the synchronizer 10. From the output of the counter-register 11, monotonically increasing codes are fed to the input of the digital-to-analog converter 2, from the output of which the monotonically increasing control voltage goes to one input of the adder 3, the output connected to the modulator 4. At the same time, the other input of the adder 3 does not receive signals, since in the adaptation mode from the output of another storage unit 15 to one input of the multiplying digital-analog preo Brazovatel 16 receives the code zero. Monotonically increasing voltage frequency modulation of the high-frequency generator 5.

The signal from the output of the high-frequency generator 5 through the controller 6 and the reference resonators 7 is fed to the input of the detector 8, the output of which produces video signals when the frequency of the high-frequency generator 5 coincides with the resonant frequencies of the reference resonators 7. These signals arrive at the input of the driver 9, from which the control Signals go to one synchronizer input 10. At the beginning of the i-ro control signal in the imaging unit 13, the code is locked from the output to the account

chick-register 11. At the end of the i-ro control signal, the driver 13 generates a code corresponding to the average resonant frequency of the i-ro resonator. This code is stored in the 1st memory location of one storage unit 12. At the same time, the increment generator 14 generates a code equal to the difference between the codes of average resonant frequencies i-ro and (i-1) -ro cycles. This code is stored in the i-th memory location of another storage unit 15.

After completion of the adaptation, the device automatically switches to the identification mode,

In the identification mode, the proposed device operates as follows.

zom. Counter register 11 is switched to register mode. Codes from the output of one storage unit 12 through the counter-register 11 are fed to the input of the digital-to-analog converter 2,

the output of which is formed by the voltage corresponding to the average frequencies of the reference resonators 7. From the output of the other storage unit 15, the code corresponding to 1-slope amplitude

the frequency characteristic of the high-frequency generator 5 is fed to the input of a multiplying digital-analog converter 16, to the second input of which a harmonic modulating signal is fed from the former 17. The output of the multiplying digital-analog converter 16 produces a harmonic signal whose amplitude is inversely proportional to

the average slope of the amplitude-frequency characteristics of the high-frequency generator 5. From the output of the adder 3 amplitude-modulated signal is fed to the input of the high-frequency

generator 5. From the output of the high-frequency generator 5, the frequency-modulated signal through regulator 6 is fed to the input of the circulator 19, to the other input of the balanced mixer 21

and to the input of the reference resonators 7. The signals from the output of the imaging device 9 are not used in the identification mode. The signals from the output of the circulator 19 using the transmit-receive antenna 20

emitted into space. When the response unit 1 is in the directivity range of the transmit-receive antenna 20, the response signals through the transmit-receive antenna 20 and the circulator 19

arrive at one input of the balanced mixer 21, where the selection of response signals is carried out. After amplification in the balanced amplifier 22, filtering in the narrowband filter 23 and detection in the detector 24, the signals arrive at the input of the controlled integrator 25, where information signals are accumulated in each clock of each implementation. After overwriting the signals of each clock into the dynamic storage unit 26, resetting the controlled integrator 25 with the help of signals arriving at its other input from the output of the synchronizer 10, using the dynamic storage unit 26 and the analog-digital converter 27 o uschestvl a conversion of the signals into digital form,

In drive 28, there is: a small accumulation for each clock cycle for N implementations. The adaptive poro-block 29 processes the accumulation results by several cycles and checks their compliance with the given code (for example, two out of five) with a tunable threshold. The result of the operation of the adaptive threshold unit 29 is the detected decimal digits of the number of the mobile object that accumulate in the drive 30,

The signal end of the movable object coming from the sensor 18, the decoder begins to work .31, The latter selects from the drive 30

the codes that met the fourth output the synchronous number of times for each decimal place of the number of the moving object. If one decimal digit is not recognized in the number of a moving object, the decoder 31 restores it according to the specified algorithm. If the number of unrecognized bits exceeds one, then the specified code (for example, the question code) is substituted for these bits, the generated number of the moving object is transmitted to the information block 32. At this the cycle of operation of the device ends, With the arrival of the next impulse of the beginning of the main object, the cycle of operation of the identification device is repeated. Block 32 of the information stores the numbers of moving objects and puts them into the communication line at the request of the consumer.
