one

The device relates to telemetry systems for transmitting the readings of the calculating mechanisms and the angle of rotation.

Known transducers of angular movements in the code that contain the startup unit, a clock pulse generator and p decade blocks, in each of which the inputs of the sensing elements are connected to the decade distributor, and the outputs to one of the inputs of the AND logic elements, to the other inputs of which the trigger outputs are connected interrogation of sensitive elements and control triggers, the output of logic elements "AND through a logical element" OR is connected to one of the inputs of the triggering trigger, the other input of which is connected to the triggering unit , the trigger trigger output through the key is connected to a clock pulse generator.

The described device is characterized in that in each decade unit there are additionally installed two sensitive control elements, the inputs of which are connected to the start-up unit, the reset bus of the decade distributor and one of the control trigger inputs, the output of the first sensitive element, is connected to the input of one of the control triggers, the output the second sensing element is connected to the input of another control trigger via the logical element "OR.

{This implementation has improved the reliability of the converter.

FIG. 1 shows a decade code converter mask; in fig. 2 - clip

decade block; in fig. 3 is a block diagram of a converter.

The described device contains a decade code mask /, on which information track 2 and code track 3 are located, the clip of the decade block 4; information sensitive elements 5; additional sensitive controls 6 and 7; launch unit 8; control triggers 9 and 10 logic elements "And / 7 and 72; decade distributors 13; triggers polling sensitive elements 14; triggering trigger 15; keys 16; driver 17 output signals, the generator 18 clock pulses; logical elements “OR 19 and 20.

The rotation of the volumetric counter shaft is transmitted by a decadic code mask / (FIG. 1), rigidly associated with the decade code masks of the leading bits of the triple-reduction gearboxes (gear ratio t

1:10).

The decade code mask has two code tracks: information 2 and code 3 for uniquely retrieving information. The uncut part of the code track corresponds to the code “O, and the cut out code“ 1,

Information is picked up by means of sensing elements 5, for example, transformer ones installed in cages of decade blocks 4 (Fig. 2), between which the decade code mask L rotated from permallo rotates.

Information sensitive elements 5 are arranged evenly around the circumference of the decade block (ten for each decade) in accordance with the numbers of the digital drum of the counting mechanism.

The use of the decimal code for converting the rotation angle provides an error of ± 1 within one decade.

On the decade blocks 4, there are additionally two sensitive controls B and 7, which allow unambiguous retrieval of information.

Differentiated single impulse issued by the start-up unit 8 (Fig. 3), with the leading edge switches control triggers 9, 10, thereby applying a potential to the logic elements "And //, 12, sets decadal distributors 13 to the zero position, switches the polling triggers of sensitive elements 14 (necessary in order to not pick up a false signal when reading information corresponding to “O,”), the potential is removed from the second inputs of the logic elements “AND //, 12, and the back front interrogates the sensitive control elements 7 and switches the trigger 15 triggers, the unlocking keys 16.

The inputs of the decade distributors 13, in line through the shaper 17 output signals and the input of the trigger polling sensitive elements 14 begin to receive pulses from the generator 18 clock pulses. The polling triggers of the sensitive elements 14, switching from the first clock pulse, apply the potential to the logical elements 11, 12.

At the outputs of decade distributors 13, pulses appear alternately feeding the inputs of information sensitive elements 5. Depending on the position of the decade code masks 1, at the outputs of the sensitive elements 5 of each decade, the signals passing through open logical elements “And and (corresponding to odd numbers) or 12 (corresponding to even numbers), which, having passed through the logical elements“ OR 19, switch triggering triggers 15, locking key cut 16 inputs of decade distributors 13.

Thus, a number of pulses will pass into the line, which uniquely determines the number established at the time of the survey on decade blocks.

In the case of counting uncertainty, at the boundary of two numbers at the output of the sensing element 7 (transition from an odd number to an even number) a pulse appears that switches the trigger of control 9 to a position that removes the potential from the input of the logic element “11. the logical element < 12 > In the case of a transition from an even number to an odd number, the logical element ' 12 ' is closed, and the information pulses pass through the logical element < 11.

In order to reduce the error due to the multi-counting of the converter and

transitions from one number to another in the higher bits, the control of the triggers 9 is additionally carried out through the logical element OR 20 at all the lower bits, which eliminates the acquisition of signals corresponding to odd numbers.
