Additionally, a register 20, an additional delay element 21, a converter are introduced on the rotating part.

22 consecutive codes in parallel, optional, additional driver

23 impulses, rotor and stator windings of rotary transformer 24, on the base part - additional amplifier 25, parallel code converter 26 to serial and additional register 27, delay element 28 ..

The device works as follows.

At the moment of switching on the devices arranged on the fixed part, their elements (counters, registers, etc.) are set in an arbitrary state, with the exception of counter 19, which is set to O, which closes the element AND 16 from the converter 15 to the register 17. At the same time, the pulses received from the output of the generator 18 do not pass through the element 16 to the amplifier 14.

At the moment of supplying power to the rotating part, all elements, except for the counter 85, are set to an arbitrary state. Counter 8 is set to O, which causes the recording of a randomly established ADC code 4 to the converter 7, after a time delay in element 21, the register 20 of the accidentally established transform code l expires, 22 after the time delay in element 5 has expired the unit of the randomly established state of the counter 3S a after the time delay in element 6 has elapsed — the start of conversion of the sensor signal D / to the ADC 4, which is determined by the state of the counter 3 and connected by the switch 2 to the ADC 4. After a time, ne go to signal conversion at the ADC output code 4 is formed.

When the first control signal is fed through the control bus to the second input of the counter 19, its most significant bit is set to which it is fed to the second input of the transducer.

reduction on the rotating part. In addition, 1, the passage from the output of the counter 19 through the element 28 with a delay sufficient to finish rewriting information from the register 27 to the converter 26, to the input of the element 16, allows the passage of clock pulses from the output of the generator 18 through the element 16 to the amplifier 4, where the pulses are amplified and fed to the stator winding of the transformer 12. At the same time, the clock pulses are sent to the counter 19, the converter 26, forming at its output a sequence of pulses corresponding to the code recorded in the converter 26, and to the first one converter 15. The pulses coming from the output of converter 26 are amplified by the amplifier 25 and fed to the stator winding of the transformer 24. From the outputs of the transformers 12 and 24, the clock pulses and information pulses transmitted to the rotating part are delivered to the drivers 10 and 23, where they are converted in a form suitable for the operation of subsequent blocks. From the output of the driver 10, the clock pulses arrive at the input of the counter 8 and the converter 7, forming at its output a sequence of pulses corresponding to the code recorded in the converter 7. The pulses coming from the output of the converter 7 are amplified by the amplifier 9 and fed to the rotor winding of the rotary transformer 11. From the stator winding of the transformer 11, the pulses are fed to the input of the imaging unit 13, where they are converted into a form suitable for further work. From the output of the imaging unit 13, the pulses arrive at the second input of the converter 15, the latter perceives the incoming signals as 1, if the second input of the converter 15 receives a high signal level with a high signal level at the first input of the converter 15, and as a logical O, if the second input arrives low signal level with a high signal level at the first input.

pulse to the second input pulse will not arrive, it will be perceived as receipt of O.

In a similar manner, information is being written to the converter 22 from the imaging unit 23, and the clock pulses are the pulses arriving at the second input of the transducer 22 from the imaging unit 10.

Upon receipt of the trailing edge of the last clock pulse, the number of which corresponds to the size of the transmitted codes, a change of 1 to O occurs at counter 8 at its output. The change signal 1 to O enters the input of converter -7, causing the ADC 4 and counter 3 codes to be written to it , as well as the inputs of the elements 21, 5 and 6 delay.

After the delay time determined by the delay element 21 (required to set the information n the output of the converter 22 after the last clock pulse from the generator 10 to the converter 22), the signal O, coming from the element 21 to the second input of the register 20, records the parallel code from the converter 22 into a register 20, the output of which is the output of the device on the rotating part of the object.

Through the delay time determined by the delay element 5 (required for the tracing of the ADC 4 codes and counter 3 to converter 7), the signal from its output goes to the input of counter 3, which changes its state by one. The counter code 3 is fed to the first input of the converter 7 and to the control input of the switch 2, which is connected to the first input of the ADC 4 parameter sensor

"and

corresponding to the new state of the counter 3.

After the time delay, determined by the delay element 6, the signal from its output goes to the second input of the A / D converter 4, causing the conversion of the signal connected by the switch 2 of the parameter sensors from group 1 of the sensors to the parallel code to start.

At the same time, when the trailing edge of the last clock pulse arrives at the counter 19, the number of which corresponds to the transmission width0

codes, the output of the counter 19 is a change of 1 to O.

The receipt of the specified signal through the delay element 28 at the second input of the AND 16 element closes it and the formation of clock pulses at the output of the AND 16 element stops.

At the same time, the signal O is fed to the second input of register 17, which causes the recording of a parallel code containing the code generated by ADC 4 and the code of counter 3 from the converter 15 to the register 17, the output of which is the output of the device.

The arrival of a new signal via the control bus at the device input leads to the transmission of information received via the information bus to the rotating part, and the information measured by the parameter sensor D d 41 to the fixed part, etc. Thus, the device provides bidirectional information exchange between the fixed and rotating parts of the object.
