Description

The proposed tank ballistic computer (TBV) belongs to the field of computer technology and is designed to generate aiming angles and lateral anticipation of the gun when firing artillery and guided missiles, to develop a time interval for installing a fuse day of artillery shells with detonation on the trajectory, to generate a signal "Shooting" and time delays when firing guided projectiles, developing a resolution zone for a shot in the tank’s fire control system (SUOT).

Known computing device for firing (US patent No. 3739153, CL G 06 G 7/80), containing a handset, buttons, relays, scales for entering information using potentiometers. The calculating and solving device calculates the anticipated coordinates of the target and provides information on the dependence of the aiming angle on the range to the target, which is read from the scales of the potentiometers visually. This computing device of the electromechanical type has low accuracy and relatively low speed and requires constant attention of the gunner during operation.

Also known ballistic computer (UK patent No. 1277251 for CL G 4 G), containing the first multiplier device and the second group of multiplier devices. The first multiplier device multiplies the range signal by an amount depending on the type of projectile and special conditions to obtain a normalized range signal. The second multiplying device multiplies the signals of the flight time and the maximum vertical elevation angle by the corresponding constants to take into account deviations of the firing conditions from normal. An analog type ballistic computer has high speed, but relatively low accuracy due to errors in analog multiplier devices.

The calculations are carried out in analog-digital form. Ballistic functions are approximated by linear-fractional functions of the form

This calculator has long been considered the best example, however, during operation, the following disadvantages were revealed.

1. The relative angular velocity of the target in the vertical plane is not taken into account, which leads to a sharp decrease in efficiency when shooting at moving targets in mountainous terrain and to the almost impossibility of firing at low-flying targets (such as a helicopter), since the lead angle in the vertical plane is not generated. In this case, the magnitude of the aiming error is numerically equal to the lead angle and can be determined from the drawing (see Fig. 3), where D is the distance to the target; V _c - target speed; N - vertical movement of the target; ψ is the angular movement of the target; θ is the angle between the direction of movement of the target and the horizontal plane.

Obviously, for D >> H,

,

,

where t is the current time.

Then the relative angular velocity of the target in the vertical plane is defined as

and the value of the lead angle at flight time t _p should be

For example, if D = 2000 m (with t _p = 2.76 s),

V _c = 5 m / s, Θ = 10 °, the aiming error will be

which practically leads to misses when shooting.

2. There is no accounting for the portable velocity of the projectile when the tank is moving. The relative change in the initial velocity of the projectile is

where V _T is the speed of the tank;

q - heading angle;

V _o - the initial velocity of the projectile.

At D = 2000 m V _T = 20 m / s.

The error value (calculated by the prototype algorithm) is 1.3 '.

3. There is no accounting for the angle between the gun and the hull of the tank, which leads to a number of errors:

a) when the tank moves, the relative angular velocity of the line of sight can occur if the line of sight does not coincide with the direction of the speed of the tank (for example, the tank moves on a slope). Since the relative angular velocity of the target is defined as the speed of the line of sight when tracking the target, this leads to the appearance of a fictitious angular velocity of the target and, in turn, to the aiming error. The magnitude of this error can be determined from the drawing (see figure 4), where D is the distance to the target; V _T - tank speed; H - vertical movement of the tank; ψ is the angular displacement of the line of sight; α is the angle of aim (between the gun and the line of sight); φ is the angle between the gun and the hull of the tank.

When D &γτ; &γτ; N

where ω _wf is the fictitious relative angular velocity of the target;

t _p - flight time

With D = 2000 m, V _T = 5 m / s and an angle between the line of sight and the hull of the tank at 10 °, the error is 4.1;

); V_o - начальная скорость вылета снаряда (вектор

); V - итоговая скорость вылета снаряда (вектор

); φ - угол между корпусом танка и пушкой в вертикальной плоскости.b) when the tank moves, it is necessary to take into account the change in the aiming angle due to the vector addition of the projectile and tank speeds. This causes a change in the direction of the velocity of the projectile, leading to an error in the aiming angle. To avoid it, it is necessary to introduce a correction in the angle of aim. The magnitude of the error can be determined from the drawing (see figure 5), where V _T is the speed of the tank (vector

); V _o - the initial velocity of the projectile (vector

); V - total projectile departure speed (vector

); φ is the angle between the tank body and the gun in a vertical plane.

The value by which the aiming angle is changed can be defined as

When V _o >> V _T and for small values of y,

At V _T = 10 m / s, V _o = 800 m / s, φ = 5 °, the error is 3.75 ^' .

4. There is no accounting for the target’s own speed, which leads to errors when firing at a moving target.

The magnitude of the error can be estimated approximately, considering the linear dependence of the aiming angle on the range for small deviations in the vicinity of the selected point, then

Δ α ≥ K _d V _c (t + t _p ),

where K _d - linearization coefficient;

V _c - target speed;

t is the time between measuring the distance to the target and firing a shot;

t _p - flight time.

For example, when the range to the target is 2000 m (K _d уг 0.043 ang.min / m, t _p = 2.76 s) t = 2 s, V _c = 10 m / s, the error is 2.1 '.

5. There is no accounting for changes in the aiming angle when shooting with the presence of a side roll. This change can be expressed by the function:

α = α ₁ cos γ,

where α is the aiming angle, taking into account the lateral roll;

α ₁ - aiming angle defined by the shooting tables taking into account deviations of the shooting conditions from normal;

γ is the angle of the side roll of the tank.

From the above dependence it follows that the presence of a lateral roll of 10 ° leads to an error in calculating the aiming angle of 1.5%.

6. A portion of the shots by guided missiles is fired when the target is obviously outside the affected area, depending on the distance to the target and its speed. The absence in the TBV calculations of the shooting zone leads to a meaningless loss of guided missiles and a decrease in the effectiveness of guided weapons.

7. The calculator does not have a device for calculating the time intervals for installing the fuse in artillery shells with detonation on the trajectory, as a result of which the device for setting the time intervals using the same input data was needed to determine the flight time and, accordingly, the time for installing the fuse: range to the target, atmospheric pressure, air temperature and charge, change in the initial velocity of the projectile, expansion of the barrel.

The aim of the present invention is to increase the efficiency of shooting by increasing the accuracy of the calculations. This goal is achieved by the fact that in a tank ballistic computer containing adders, switches, potentiometers for entering corrections for changing the initial velocity of the projectile, expanding the bore, air temperature, charge temperature and atmospheric pressure, a manual range input unit, low-pass filters, the first and second digital-to-analog converters, the analog inputs of which are connected respectively to the voltage reference buses of the vertical (α) and horizontal (β) guidance channels, the control inputs of the first commutator The ora are connected to the outputs of the ballistic switching unit, and the analog inputs are connected to the outputs of the input units for individual projectile angles in the vertical and horizontal planes, a range register, at the inputs of which there is a range code, an analog-to-digital converter, the trigger input of which is connected to the first output of the control device and synchronization, the first input of the first adder is connected to the vertical angle sensor, and the second input is with the output of the first digital-to-analog converter, the output of the first sum the torus is the first TBV output - the vertical guidance channel, the first input of the second adder is connected to the horizontal angle sensor, and the second input is the output of the second digital-to-analog converter, the output of the second adder is the second TBV output - the horizontal guidance channel, analog memory blocks, decoupling amplifier, the first controllable low-pass filter, the first input of which is connected to the fault of the sensor of the relative angular velocity of the target in the horizontal plane, the second input - to the bus ilizirovannogo voltage, the first and second comparators

The use of digital computing devices based on microprocessors is widely known in the national economy / Goryachev A.V., Shishkevich A.A. Information management computing systems. - M.: Higher School, 1984 /. However, the use of a microprocessor-based computing device as part of a tank ballistic computer made it possible, with insignificant additional hardware costs, to introduce signals of the angle of the gun position relative to the tank hull in the vertical plane and the relative angular velocity of the target in the vertical plane into the TBF structure and take these signals into account in the TBF operation algorithm. In known technical solutions, to take into account the signal of the relative angular velocity of the target vertically, one more mode would be needed in the mode switching scheme used there to calculate the lead angle in the vertical plane

β _VO = t _with respect _to ω _B,

where β _BO is the lead angle in the vertical plane;

t _po - flight time;

ω _B is the relative angular velocity of the target in the vertical plane.

Next, it would be necessary to carry out the calculation at the output of the adder 17 functions

where the designations correspond to those adopted in the description of the prototype,

and then carry out the summation of the obtained value with the aiming angle. This would lead to a significant complication of the control device and synchronization of the prototype and the structure as a whole.

Calculation of corrections for taking into account the portable speed would be practically impossible due to the large number of multiplication and division operations and would lead to a decrease in reliability due to the re-complication of the scheme.

sin²γ , (сигнал sinγ поступает с датчика бокового крена). При этом ошибка вычисления cos γ при боковом крене до 15° не превышает 0,06%.The use of a computing device based on a microprocessor made it possible to additionally take into account the change in the aiming angle in the presence of a lateral roll, without the need for an additional sensor emitting a signal cos γ, and the calculation is performed according to the formula cos γ = 1-

sin ² γ, (the sinγ signal comes from the side roll sensor). In this case, the error in calculating cos γ with a lateral roll of up to 15 ° does not exceed 0.06%.

It also became possible to take into account the target’s own speed of movement by re-measuring the distance to the target, while the target’s speed is determined as the following function:

where D ₁ and D ₂ - respectively, the first and second ranges to the target, measured by the range finder; t _D1 and t _D2 - times corresponding to the range measurement, read from the timer; V _T - tank speed; cos q is the cosine of the heading angle.

In addition, it became possible to calculate the shooting zone for guided missiles and to calculate the time for installing the fuse in shells with detonation on the trajectory. In this case, the same data is used as for solving the main ballistic problem, and the hardware costs are reduced only to the introduction of the Request signal bus for installing the fuse in projectiles with detonation on the trajectory and output shapers in the matching device, which serve to issue two impulses for installation fuse and signal that the target is outside the shooting zone. In addition, the introduction of a microprocessor made it possible to increase the number of types of ammunition used only by increasing the positions of the switches of the ballistic switching unit and increasing the volume of ROM ballistic coefficients. With the analog-digital structure of the prototype, an increase in the number of ballistic types would lead to significant hardware costs, since ballistic coefficients were implemented by weight resistors and switches controlled from a ballistic switching unit.

The selection of the amplitude of the input signals of an alternating voltage of 400 Hz for subsequent conversion is carried out by means of an analog memory unit (BAS). Known devices for sampling and storage (Gnatek Yu.R. Handbook of digital-to-analog and analog-to-digital converters. Transl. From English. - M .: Radio and communication, 1982) containing an analog key, a storage capacitor and an isolation amplifier. However, in this case, the stored voltage may have an error due to the voltage difference on the common wires of the sensor and calculator and (or) constant bias on the input scaling amplifiers. So for the input signal

U_вх=U_msin ω t+ω _{см вх,}

U _in = U _m sin ω t + ω _{cm in,}

where U _m is the signal amplitude;

U _{cm in} - constant offset signal.

The voltage stored at the output of the sampling and storage device will be

U _o = U _m + U _{cm in} .

In the proposed analogue storage unit, there are two pairs of keys, capacitors, and decoupling amplifiers, and the sampling signals are applied at time instants corresponding to the maximum value of the signal to the first key and the minimum to the second key, that is, shifted relative to each other by a time corresponding to the signal half-period. Then the stored voltage at the first BAZ output will be U _{oi 1} = U _m + U _{cm in} and the second BAZ output U _{o 2} = U _m + U _{cm in} . During the subsequent analog-to-digital conversion, the codes will correspond to them:

N ₁ ≡ U _{out 1} + U _{cm ADC} = U _m + U _{cm in} + U _{cm ADC} ;

N ₂ ≡ U _{out 2} + U _{cm ADC} = -U _m + U _{cm in} + U _{cm ADC} ,

where U _{cm ADC} - own constant offset of the ADC.

Received codes are processed in a computing device according to the algorithm

Thus, errors arising as a result of bias of signals from sensors and input devices, as well as bias in the analog-to-digital conversion path, are eliminated. In addition, due to averaging of the results of two transformations, an increase in accuracy occurs.

Thus, in the proposed device, well-known features, original and well-known circuit solutions give new properties to a tank ballistic computer, namely, they increase the efficiency of firing from a tank by increasing the accuracy of calculations, including guided projectiles, and allow firing of shells with detonation on the trajectory. In addition, it became possible to increase the number of types of ammunition used. Thus, the claimed technical solution has significant differences.

The essence of the claimed technical solution is illustrated by drawings, which show the TBV block diagram (Fig. 1), a functional diagram of an analog storage unit and time diagrams of its operation (Fig. 2).

Tank ballistic computer operates as follows. The computing device 35 through the address selector 36 cycles through the matching device 37. The matching device 37 consists of a number of triggers and a bus driver with a third state. External control signals that determine the operation mode of the TBW are connected to the inputs of the triggers. When polled, the contents of the triggers are read into the computing device 35, after which the triggers are reset. Upon receipt of a signal "ZAPD", indicating the measurement of range, the computing device 35 through the address selector 36 addresses the range register 1 and the switching unit ballistic 2 and reads information about the range code and the type of ballistics. The outputs of the range register 1 and the ballistic switch block 2 connected to the data bus have a third state. After that, information is read from the BOSE 39. At the same time, according to the signals from the address selector 36, the address switch 34 connects the address bus of the computing device 35 to the address inputs of the BOSE 33, the BOSE 33 is set to "Read" mode, the data switch 32 connects the outputs of the BOSU 33 to the bus data. The information is read by changing the low order bits of the address bus while maintaining the high order bits of the address, which determine the reading mode from the BOSE.

The range value D is read from the range register 1. The measurement time range t _{D is} read from the timer 38 at the corresponding address, the timer outputs have a buffer with a third state and are connected to the data bus by a signal from the address selector 36.

To the inputs of the switch 13 are also connected a signal about the speed of the tank V _T and the heading angle cos q through the BAZ 12. The output of the switch 15 is connected to one of the inputs of the switch 25, to the remaining inputs of which are connected to the lateral wind sensor W through the low-pass filter 14 and BAZ 16, the angle sensor of the gun relative to the tank body φ through the low-pass filter 15 and BAZ 17, signals of the relative angular velocity of the target in the horizontal plane ω _g through the low-pass filter 18 and BAZ 20 and in the vertical plane ω _B through UFNF 19 and BAZ 21, the signal of the lateral roll sensor of the tank γ through BAZ 22, signals from the angle sensors of vertical guidance ДУБН through BAZ 24 and horizontal guidance of the ARC through BAZ 27, differential signals ДУВН - α through BAZ 26 and ДУГН - β through BAZ 29.

where the filter time constant T is determined by the following relation:

A detailed explanation of the work of the UFNF is described in the prototype (AS 151447) and is not given here.

The signals from the switches 13 and 23 through the decoupling amplifier 50 are fed to the input of the ADC 31. The sequence, the passage of signals and their conversion is determined by the address bus of the control and synchronization device 51, which is also connected through the address switch 34 to the address inputs of the BOZU 33, which provides an unambiguous correspondence between the converted signal and the address at which the result of the analog-to-digital conversion of this signal from the ADC 31 through the data switch 32 is recorded in the BOSE 33. Recording is carried out according to the signal with control and synchronization devices 51. The direction of data transmission from the ADC 31 to the BOSU 33 and the addresses from the control and synchronization 51 to the BOSU 33 is basic. Switching switches 32 and 34 occurs only when reading data from the BOSU 33 to the computing device 35, which takes a short period of time (1 μs for one signal).

Thus, in the BOSE 33 at a predetermined fixed address contains digital codes corresponding to voltages from potentiometers and input information sensors.

Information about the signals λ α _j , λ β _j , ΔТ _В , ΔТ ₃ , ΔН, ΔV _о , Δd, V _Т , cos q, W, φ, sinγ, ω _g , ω _{B is} used for calculations using the above algorithm. Information about the signal of the manual range Dr is used if the computing device 35 reads the active level from the matching device 37 using the Manual / Auto signal, which indicates the need for manual range input. In this case, information from range register 1 is ignored. Information about the signals DUVN DUGN and differential signals DUVN-α and DUGN-β is not directly required for calculations and can be used to control the development of the issued signals by the system.

Accounting for the various steepness of the signals from the sensors and their normalization to the form necessary for the calculations is carried out in the computing device 35 by multiplying by the corresponding normalization coefficients stored in the ROM of the computing device 35.

The digital codes of the values of the aiming angle α and lateral lead β obtained as a result of the calculations are recorded in registers 39 and 40, respectively. Recording is performed according to the signals from address selector 36 when the corresponding address appears on the address bus of computing device 35. Conversion of binary digital codes into analog signals AC voltage necessary for the operation of the system is carried out using multiplying DACs 42 and 43, the inputs of which receive the reference voltage of the channels, respectively, of vertical and horizontal isontal guidance of the required phase. The signals from the DAC 42 and 43 are fed to the subtracting inputs of the adders 25 and 28, respectively. The other inputs of the adders 25, 28 receive signals from the sensors of the angle of guidance and the signals of the electrical alignment sight Vyv and Vyv respectively. In this case, the output of the adder 25 produces a differential signal

α _Σ = DEVN-α ± Out α,

and at the output of the adder 28

β _Σ = DUHN-β ± vy β.

The signals α Σ and β Σ are the output signals of the TBW and are fed to the inputs of the drive, which carries out guidance, processing these signals to zero. As a result, with α _Σ = 0 and β _Σ = 0 (after mining), we have

OVN = α ± Out α;

DUGN = β ± Vyv β,

that is, the position of the gun (determined by the signals from the guidance sensors) corresponds to the aiming angles α and lateral lead β generated in the TBV.

The signals of the electrical alignment Vyv and Vyv β are necessary in order to compensate for the residual signal of the sensor at the coordinated position of the sight, and are entered during adjustment in the tank. The adders 44 and 48, the comparators 45 and 49, the potentiometers for adjusting the width of the zone 46 and 50, the coincidence circuit 47 comprise a block for generating a shot resolution zone, the operation of which is described in detail in the description of the tank ballistic computer.

In the inventive calculator uses a slightly different technical solution. Difference signals α Σ and β Σ, which are essentially signals of the deviation of the gun from the calculated angles, are fed to BAZ 26 and 29. BAZ 26, 29 are designed so that the paraphase voltage is removed from their outputs (see the description of the operation of the BAZ below), that is, at the outputs of BAZ 26 we have

where U _cm is the constant bias arising as the sum of the constant bias of the SHOW signal relative to the common wire, the intrinsic offsets of the DAC 42 and the adder 25, the bias of the adder 25 from the constant component by the signal Vyv α. Since the outputs of the BAZ 26 are connected to the bipolar inputs of the adder 44, at the output of the adder we have

Thus, the above scheme allows to suppress a constant bias, which otherwise would lead to a shift in the resolution zone of the shot. The voltage from the output of the adder 44 on the comparator 45 is compared with the threshold entered by the potentiometer of the width of the resolution zone 46. In the case of U _{output Σ} <U _pores (mismatch is small), a high (resolving) voltage level is supplied to the matching circuit 47. The circuit along channel β works similarly. Upon receipt of the signal to the calculator on coincidence circuit 47, the power of the PSS coincidence circuit from the start button of the sight will signal “Shot resolution zone” (ZRV) will be issued only if there are high levels from comparators 46 and 49, that is, a shot will only occur if the gun position coincides with the angles developed by the calculator (with the exception of the allowable mismatch introduced from potentiometers 46 and 50).

Upon receipt of a reset signal to the matching device 37, which indicates a reset of the measured range, the TBW gives the angles α and β equal to zero.

When choosing the ballistic of a guided projectile, the calculation of the aiming angles and lateral lead is performed according to the following algorithm, depending on the receipt of the “Exceed” signal to the matching device 37:

where the designations of the signals correspond to those in the main algorithm, the relative angular velocities of the target ω _B and ω _{g are} read by the computing device 35 from the BOSU 33 in the same way as in the normal mode. When working with a guided projectile upon receipt of the signal "Descent" and the presence of the signal "Excess", TBV generates a signal about the delay time (τ _back ) of the guided projectile, designed to work in a dusty area. The calculation of the delay is carried out according to the following relationship:

τ _ass = -3.4 + 3 · 10 ^-3 (D-Δ D) (1-0.65 · 10 ^-3 · Δ T ₃ -

1.2 · 1 ^-3 · Δ T _B + 0.31 · 10 ^-3 · Δ N),

where Δ D = (V _T · cos q + V _cf ) ((t _cx -t _ISM );

V _tsf - fictitious target speed equal to 8.34 m / s;

t _cx -t _ism - time interval between the descent of a guided projectile and the moment of measuring range.

The issuance of the signal τ _ass is as follows. Through the address selector 36, the current time is read from the timer 38, after which the computing device 35 sets the active level on the data bus in a certain category, and on the address bus the address of the matching device 41, which is a register whose outputs are connected to the signal conditioners of the required level, inputs - to a data bus, and the write input - to an output of the address selector 36. as a result, the output τ _backside matching device 41 a signal appears. After a time numerically equal to the calculated value of τ _ass , there is a repeated appeal to the matching device 41 and recording the passive level for this discharge. In this case, the generation of the output signal τ _ass stops.

The use of a digital computing device allows the calculation of shooting zones for a guided projectile. The calculation is carried out according to the following algorithm:

ZS = P ₁ + P ₂ + P ₃ + P ₄ ,

where ZC - signal "Prohibition of shooting";

P ₁ P ₂ , P ₃ , P ₄ - signs of restrictions:

·t_пол,P ₁ = 0 for D ₂ ≤ D _max +

T _floor

,P ₂ = 0 at ω _g

,

P ₃ = 0 at ω _B ≤ 0.59 ^deg / _s ,

P ₄ = 0 for φ ≤ 12 deg,

where D _max = 5000 m, t _floor = 15.5 s,

Д₁ - дальность, измеренная оператором; Д₂ - дальность, измеренная в течете времени Δ t=1... 5 с после измерения Д₁, φ _o=0,6 град/с.

D ₁ - range measured by the operator; D ₂ - range, measured in the course of time Δ t = 1 ... 5 s after measuring D ₁ , φ _o = 0.6 deg / s.

The signal level ЗС corresponding to the calculated one is recorded in the matching device 41 and from the output ЗС of the matching device 41 it enters the executive device. When choosing projectile ballistics with detonation on the trajectory, the angles α and β are generated in the same way as for the standard type of ballistics. In addition, the fuse installation time is calculated t _y = t _p / 512, where t _p is the flight time, taking into account deviations of the firing conditions from normal, calculated in the algorithm.

Upon receipt of the request signal to the matching device 37, the processor 35, through the matching device 41, gives out two pulses with an interval between them numerically equal to the time t _y . The issuance of pulses is carried out similarly to the generation of the signal τ _ass described above.

The control and synchronization device 51 operates as follows. The input of the shift register 52 is connected to the “End of conversion” output of the ADC 31, at the end of the analog-to-digital conversion, the conversion result is recorded sequentially from the outputs of the register 52 into the BOSE 33, the addition of one to the address counter 53 and the start of the next conversion. The low-order bits of the address counter 53 are connected to the control inputs of the switch 23, and the high-order bits are connected to the inputs of the switch 13. Due to this, the main conversion cycle can be distinguished, during which all signals connected to the switch 23 and one of the signals connected to the switch 13 are converted , and a complete conversion cycle, during which all analog signals are converted and a complete update of the information occurs. The above organization of the control and synchronization device 51 allows increasing the frequency of signal conversion from the main sensors due to the fact that the signals connected to the switch 13 are either quasi-stationary or change an order of magnitude slower than the signals connected to the switch 23.

Since the signals from the sensors have different phase shifts relative to the reference voltages, and sampling and storing the amplitude values of the signals on the BAZ should be carried out at the time the signal reaches its maximum, synchronization of the sampling signals with the reference signal is necessary. For this cycle, a period counter 54 is used, which is reset to zero each reference voltage period by a signal from the edge selection circuit 55. The outputs of the counter 54 are connected to the address inputs of the ROM 54, in which information corresponding to the phase shifts of all signals relative to the reference voltage is flashed. Decoder 57 is used to increase the number of device outputs and converts the binary code from ROM 56 directly into sample signals connected to the sample inputs of the BAZ.

и на конденсаторе 61 запоминается значение напряжения -U_m+U_см. Развязывающие усилители 62 и 63, включенные в режиме повторителей, служат для предотвращения разряда запоминающих конденсаторов 60, 61, и их выходы являются выходами БАЗ. При считывании давних в вычислительное устройство 35 осуществляется усреднение результатов преобразования:BAZ 12, 16, 17, 20, 21, 22, 24, 26, 27, 29 work as follows. A memorized AC voltage signal is supplied simultaneously to the inputs of the analog switches 58 and 59 (see figure 2). The control input of the key 58 receives the sampling signals from the decoder 54 at time instants corresponding to ψ + π / ₂ , where ψ is the phase shift for this sensor, the key 58 is opened, and the voltage value is set on the capacitor 60, numerically equal to U _m + U _cm where U _m is the amplitude of the alternating voltage, U _cm is the constant offset of the signal. The control input of the key 59 receives a signal at a time

and on the capacitor 61, the voltage value -U _m + U _{cm is} stored. Decoupling amplifiers 62 and 63, included in the repeater mode, serve to prevent the discharge of storage capacitors 60, 61, and their outputs are the outputs of the BAZ. When reading the long-standing in the computing device 35, the conversion results are averaged:

where N is the received signal code; N ₁ and N ₂ - respectively, the results of voltage conversion from the first and second outputs of the BAZ. In this way, errors resulting from a constant bias of the signals are eliminated, and as a result of averaging, an increase in accuracy occurs.
