(54) DEVICE FOR CONTROL

CONVERTERS

CORNER CODE

- The invention relates to automation and computing.

A device for control is known; Angle-code converters 1, containing a drive mechanism, kinematically connected to an angle-code converter shaft under test, a real code change signal generating unit, a decoder, a pulse generator, a key element, a counter and a playback unit,

It is also known a device for controlling angle-code converters, 2, containing a drive, a decoder, a trigger, a block of reference signals, key elements, a block, time slots of errors, a counter.

The closest technical solution to this invention is; device for controlling angle-code converters containing the first decoder connected via a trigger to the first input of the key element, the second input of which is connected to the output of the pulse generator, the input of the deshifter and the real code changer forming unit are connected and connected to the output of the checked angle converter the code connected to the drive and the playback unit 3. .

However, the procedure for controlling angle-code converters on known devices, which is associated with determining the quantization reproduction error or the total error, is very cumbersome, which reduces the accuracy and speed of the result.

The aim of the invention is to increase the speed of control of angle-code converters.

This goal is achieved by introducing

5, the proposed device of the delay unit, the second counter, the adder, the second decoder, the register and the AND element, the output of the real code change signal generation unit is connected directly to the first inputs of the decoder and the playback unit and through the delay unit to the second input of the first counter and the first input of the registrar5 Рз the output of the key element through the second counter is connected to one of the inputs of the element I, the output of the second counter is connected to the second input of the decoder directly and through an adder to the other input of the element and AND, whose output is connected to the second input reproducing unit, one of the outputs of the decoder is combined with a third input of the first counter, Auto swarm decoder output is connected to the second input memory / output of which is connected to the third input of the reproducing unit. The block diagram of the proposed device is shown in the drawing. It contains a decoder 1, block. generating signals of a real code change 2, trigger 3, pulse generator 4, block. Delay 5, key element b, counter 7, decoder 8, counter 9, adder 10, register 11, element 12, block 13, drive 13 14 and the angle converter code 15. -. .. :. The device works as follows. . . . The drive 14 produces a uniform rotation of the transducer shaft ut-code 15. When the signal of the zero code is output, the decoder 1 is triggered at the output of the last one, trigger 3 overturns, opening the key element 6 for passing pulses from the pulse generator 4. 7. MF: em chik 7 is proportional to the quantum conversion; The angle-code operator 15. The impulse coming from the block for generating signals of the real code 2 change allows the decoder 8. to receive and output to the register 11 numbers written in counter 7. The same pulse gives the command to the block 13 to record the register. 11 and through delay unit 5, the counter 7 and register 11 are reset to their initial state. The scheme is ready to receive the next pulse of a real code change from block 2. It should be noted that in the process of the device operation in the counter 7 there is an accumulation of measurement errors. This is due to the fact that there are cases of coincidence of the signals of a real change of code and pulses that are received from the pulse generator 4, as a result of which the latter will not be calculated by the counter 7. Such accumulation: compensation is compensated by periodically writing the unit to the counter J decoder 8. The frequency of the recording is determined by the parameters of the device circuit. As a result of the full rotation of the shaft of the angle-code converter driver 15, the decoder 1 triggers, returns the trigger 3 to the initial state, the measurement process ends. Monitoring the correct operation of the device is carried out as follows. The pulses of the Impulse Generator 4 are constantly calculated by the counter 9. And the pulses counted by the counter 7 are summed up in the adder 10. The results of the calculation of the wide pulses in the counters 7 and 9 are compared on the element 12 and shown in the playback unit 13. In case of coincidence of the pulses The playback unit at the next recording of the number from the register 11 gives information about the operation of the device. It should be borne in mind that the delay of the real code change signal by the delay unit 5 must be less than the period of the pulse from generator 4. Thus, in the playback unit, the time intervals of all the quanta of the converter will be recorded. angle code 15. - The economic effect from the use of the proposed converter is due to the above mentioned technical advantages.
