28, the second input of which is connected via a key 29 to a voltage source and. The third input of the pulse counter 18 is connected to the output of the generator 14 clock pulses,

The device works as follows.

When the key 29 is pressed, the voltage is supplied to the second input of the starting circuit 28, which generates a single reset pulse, resetting the keys 15. and 16, pulse counters 9, 10, 8 and the counter 24 commands.

From the moment the pulse of the 5th pulse is terminated, 14 clock pulses from the generator start to give pulses to the first input of the command breaker 21, from the output of which they arrive at the first input of the counter 24 commands, where they are summed up. The code combinations at the output of the command counter 24, corresponding to the set number of pulses, are parallel to the code, are detected at the inputs of the comparators 22 and 23 and at the first input of the decoder 25, where the transducer is converted into commands for the computing unit 26, with the help of which the latter is prepared .

When the code at the output of the command counter 24 coincides with the setting code of the comparator 22, a potential signal appears at the output of the latter, the front of which interrupts at the second input of the interrupter 21 of the pulse passing commands from the generator 14 clock pulses to the output of the interrupter 21 of the commands. At the same time, this high logic level signal arrives at the second input of the And 7 element, preparing the latter for the passage of pulses from the pulse sensor 1 of the material length. Device enters

the first input of the element is And 17, and from its output to the third input of the descriptor and then directly to the computing unit 26, where they summarize c.

When the codes at the outputs of the pulse counter 9 and the software switch 13 coincide, a potential signal appears at the output of the comparator 11, which is fed to the first key 15 of the information processing unit 4. With this signal, the key 15 is transferred to the passive state, providing | Chiva -.dnie the permissive signal of the second input element And 17 and on the front of the signal arriving in parallel to the fifth input of the interrupter 2 commands, prohibits interruption. As a result, the pulses from the generator 14 clock pulses received at the first input of the interrupter 21 commands, pass to its output and arrive at the first input of the counter of the 24 commands. The code combinations at its output go to the first input of the decoder 25, where they are converted into commands for the computing unit 26, recording the accumulated number of pulses in memory and preparing the computing unit 26 to receive information via the pulse sensor 2 of the material length.

The end of the execution of this subroutine is determined by the coincidence of the output code of the counter 24 commands with the tuning code of the comparator 23, when a potential signal is generated at its output, which arrives at the third input of the command breaker 21 thus preventing 14 pulses from the generator output to its output. At the same time, this signal is fed to the first input of the circuit.

the first input of the element is And 17, and from its output to the third input of the descriptor 25 and further directly to the computing unit 26, where they are summed up.

When the codes at the outputs of the pulse counter 9 and the program switch 13 coincide, a potential signal appears at the output of the comparator 11, which is fed to the first input of the key 15 of the information processing unit 4. With this signal, the key 15 is transferred to the passive state, providing | Chiva -.snie resolution signal / second input element And 17 and on the front of the signal incoming in parallel to the fifth input of the interrupter 21 commands, the prohibition of interruption. As a result, the pulses from the generator 14 clock pulses, received at the first input of the command breaker 21, pass to its output and arrive at the first input of the counter 24 commands. The code combinations at its output go to the first input of the decoder 25, where they are converted into commands for the computing unit 26, recording the accumulated number of pulses and preparing the computing unit 26 to receive information via the channel of the pulse length sensor 2 of the material.

The end of the execution of this subroutine is determined by the moment coincident. The output code of the counter 24 commands with the code of the comparator 23, when a potential signal is generated at its output, arrives at the third input of the command interrupter 21, thereby prohibiting the impulse passing 14 pulses from the generator to its output. At the same time, this signal is fed to the first input of the circuit.

The operation of the device through the channel of the pulse sensor 2 of the length of the material occurs parallel to the operation of the first sensor 1 and also starts from the moment of the discharge pulse ejected by the starting circuit 28, after which at the output of the comparator 12 a signal is generated, which arrives at the second input of the element 8 and is allowing for the passage of pulses from a pulse sensor 2 of the length of the material. In parallel. the signal from comparator 12 is applied to the second input of the prohibition circuit 20, prohibiting pulses from the generator from passing 14 clock pulses, and to the first input of the key 16 does not change the state of the last signal sent to it by the reset pulse.

With the arrival of a pulse from the pulse sensor 2 of the length of the material to the first input of the element 8 at its output, a pulse is generated that arrives at the first input of the pulse counter 10 and at the second input of the key 16, converting it to an active state, at which from its output to the first input pulse counter 18 receives the enable signal. From this time on, the cycle of measuring the base length with the pulsed sensor 2 of the length of the material begins. Pulses arrive at the third input of pulse counter 18, where they are summed up. When the codes of the pulse counter 10 and the program switch 13 coincide, a signal appears at the output of the code comparator 12, which prohibits the passage of pulses from the pulse length sensor 2 of the material (through the IW element). At the same time, this signal switches the key 16 to the passive state, removes the enabling signal from the first input of the pulse counter 18 and, acting on the second input of the prohibition circuit 20, allows the pulses from it to pass from the generator .14 clock pulses to the first input of the read element 19, pulse sequences from the output of banning circuit 20

from the pulse counter 18 to the second input of the read element 19 and then from its second output through the decoder 25 to the computing unit 26,

The feedback signal from the first output of the read element 19 is fed to the fourth input of the command interrupter 21, allowing 14 pulses from the generator output to pass to its first input. The impulses arriving at the first input of counter 24 of the commands are summed, and at its first output code S combinations occur, which arrive at the first input of the decoder 25, where they are converted into commands for the computational block 26 performing the operation of calculating the relative deformation.

The transfer pulse, which enters from the second output of the counter 24 commands (after all the settlement operations have been completed), goes to the second input of the recorder 27 and records information about the relative deformation value coming from the output of the computing unit 26 to the first input of the recorder 27..

At the same time, the same pulse arrives at the first input of the starting circuit 28, on. the output of which generates a single pulse of setting the device elements to the initial state. The cycle of the device is resumed,

On indicator 6, the second measurement cycle is highlighted. the result of the previous measurement.
