The invention relates to the field of automation and computer technology and can be used in digital devices with frequency sensors, for example, in dual-frequency interferometers measuring motion parameters.

A pulse counting device is known, the frequency dividers accumulating the adder and the multiplier setting unit, the decoupler unit, and the control unit are known.

However, this converter can be used in devices with dual-frequency sensors, for example, in dual-frequency laser motion parameters, due to the inadmissibility of simultaneous supply of pulses to both inputs of the adder, since this device uses an adder to multiply the difference in the number of pulses received by two input of this converter, to the factor K, corresponding to the coefficient of conversion of the specified difference into the measured value.

The purpose of this is to expand the class of tasks to be solved in terms of the possibility of using them with dual-frequency sensors in the converter.

This is achieved by introducing a generator, a result correction unit, a subtraction circuit, a multiplier correction block, a multiplication circuit, and the outputs of frequency dividers, whose inputs are connected to the data bus and the reference signal bus, respectively, are introduced into the pulse counting preophaser, and the output of the first frequency divider and one of the outputs of the subtraction circuit are connected

The task unit for multiplier 12, the SCRD of which is connected to the inputs of the second adder 4, is filled in the form of a key and does not change PGO. intentions. , .. i.,; ::,:. ::,.: ,,.. J. The Converter operates as follows. nochejioB8r & Noise and information frequencies are fed to the inputs of frequency dividers 1 and 2, respectively. Correspondingly, from the output of the sequence divisors -: - .- .. ...-. „„, ™ “w, 0, the pulses go to the corresponding inputs of the subtraction circuit, the clock is 3. Divisors 1, 2 and the circuit; subtractors 3 serve to expand the frequency range of the preophaser. When increasing (decreasing) per unit of current ESCHE: the difference in the number of IUnitshs coming from the outputs of frequency 93.4 Informational 2 and the reference 1 signals, from the subtraction output to the control input of which the adder 4 receives a command impulse and adds an adder to its content ( subtracts from its contents) the value of the multiplier K acquired at its inputs-i of the assignment of the multiplier 12. At a certain periodicity or once the control unit 6 passes to the corresponding input of the correction unit of the result 5 impulses from the output of the divider 1 frequency of the signal signal, which sets the trigger of the result correction block into one state, allowing the generator 7 pulses to pass to the refinement counter contained in the result correction block 5. At zero, this trigger sets the closest pulse arriving from the output of the frequency divider information signal 2 no. coinciding with the impulse triggered trigger. After each installation in the unit state of the trigger of the correction unit of the result 5 of the control unit 6 to the adder B, the command Add the contents of the summator 4 with the sign determined by the high bit of the adder 4 to its contents. With the arrival of an impulse that sets the zero state trigger block. correction result 5, from the control unit the command is given out of the contents of the adder 8 code of the correction block result 5 {t. e. the contents of the refinement counter). The frequency of the oscillator 7 is chosen relative to the frequency of the reference signal such that. there is no need to multiply the contents of the counter of the result adjustment block by. mRR tep K, set in the task block multiplier 12. At each measure, the multiplication circuit .9 produces; multiplying the contents of adder 4 by the relative deviation of the multiplier K from the value of the latter determined by the assignment block of multiplier 12, and enters the obtained value into the adder 8.
