Figure 1 shows the structure of the device; 2 is a functional diagram of the first memory block; FIG. 3 is a diagram of the second pulse shaper; Fig. 4 is a diagram of the second memory block; Fig. 5 shows timing diagrams for the operation of the device.

The device for controlling the operator's operation contains a telegraph key 1, a generator 2 (time stamps), a one-shot 3 (adjustable), an adder 4 (modulo two), a counter 5, a decoder 6, a shaper 7 of a short pulse, And 8 - 10 elements, the first 11 and the second 12 delay elements, the prohibition element 13, the block of memory 14 (transmitted sign), the second driver

15 pulses (read and write), block

16, for example, a switch 17, a first pulse shaper 18 (between the characters), a clock pulse generator 19, and an electroacoustic converter 20 with coupling circuits.

Block 14 contains the D-flip-flop 21, the register 22, the element And 23 and the element OR 24.

The shaper 15 includes a distributor 25, a one-shot 26 (adjustable), a short pulse shaper 27, a switch 28, an AND 30 trigger element 30. An OR 31 element, a button (switch) 32 and indicators 33 and 34 Operation and Control, respectively.

Block 16 contains a group of counters 35.1 - 35.4, a group of indicators 36 1-36.4 with filling counters, a group of triggers 37.1 - 37.16, the first and second groups of elements AND 38.1 - 38.16 and 39.1 - 39.16, a group of elements OR 40.1 - 40 16, a group of registers 41.1 - 41.16 memories, the first 42 and second 43 elements OR.

The device works as follows.

Preset the duration of the pulses at the outputs of the one-vibrator 7.26 and the generator frequency 19 at the speed with which the operator must transmit the characters.

Turn on the power. The counters 5 and 35, the registers 22 and 41, the distributor 25 are set to their original position, the triggers 37 to zero, and the trigger 29 to the second position (Fig. 5a), the transparency of the Work indicator 33 (Fig. 5b) is lit. The time stamps from the generator 2 output go to the first inputs of elements 8 and 9, the clock pulses from the first generator output 19 to the information input of the key 28, and from the second output to the input of unit 14 and to the third (informational) input of the switch 17.

When the operator transmits the signs of the telegraph code on the key 1, the elements of the sign (point, dash) from its output (fig.bv) through element 13, to the control input of which zero potential is fed from the first output of trigger 29, go to the line (by purpose), to the input C of the trigger 21, to the input of the element AND 23 and through the element OR 24 to the input of the trigger 21. ensure the filing of the control sign from its output through the element 23 on

the input of the register 22, to the second input of the element And 8 and to the input of the one-shot 3.

The time stamps at the output of the element And 8 through the element 11, the delay time 5 of which is equal to the response time of the one-vibrator 3, arrive at the first input of the adder 4. The leading edge of the impulse of the sign element triggers the single-vibrator 3, ensuring its appearance pulse, the duration of which is equal to the control parcel point corresponding to the speed of the operator.

The pulse from the output of the one-shot 3 is applied to the element And 9. The time 15 marks from the output of the element And 9 are fed to the second inputs of the adder 4 and the element And 10 simultaneously with the time stamps coming from the output of the element 11 to the first input of the adder 4. The clock pulse from 0 of the second generator output 19, the frequency of which corresponds to the transmission transmission bcb and a hundred times less than the frequency from the first output, fed through switch 17 to input C of register 22, will provide a record in the next 5 first element (elementary parcel) of the character applied to the input Istra 22.

If the duration of the character element, or a point or a dash is equal to or 0, respectively, is greater than the duration of the control element of the point supplied from the output of the one-shot 3, then the output of the And 10 element will not be a signal, since in the first case there is no signal at the output of the adder 4, but the second 5 case, the submission of time marks from the output of the element And 9

The rear edge of the pulse from the output of the single-vibrator 3 applied to the output of the imaging device 7 will cause a short pulse at its output 0 which arrives at the input of element 12 and at the control input of the decoder 6. Since there are no time marks at the input of counter 5, information signals at the outputs of de-5 encoder 6 will not. The delayed pulse from the output of element 12 will go to the counter input of counter 5, confirming its initial state.

If the duration of the point transmitted by the operator is less than the length of the control point, then at the end of the arrival at the first input of the adder 4 time marks from the output of element 11 at its output, the second input of the adder 4 from the output of element I 9 is outputted to 5. At both inputs of the element And 10 there will be time stamps, which from its output go to the counting input of the counter 5 The binary combination from the outputs of the counter 5 is fed to the inputs of the decoder 6 Po

At the end of the arrival of time marks at the input of the counter 5, the leading edge of the pulse from the output of the one-shot 3 will form a short pulse at the output of the driver 7, which will go to the input of the element 12 and to the control input of the decoder 6.

At one of the outputs of the decoder, there is a pulse in Wits corresponding to the number of 5 time stamps received at the counter input, which will go to the corresponding counter 35, ensuring the appearance of a single potential at its first output. A single potential from the output of the counter 35.1 goes to the input of the trigger 37.1, re-. will throw the last one and give the unit potential to the input of the element AND 38.1 and through the element OR 40.1 to the input of the element And 39.1. Similarly, a shortened point is fixed when transmitting the next element of the sign.

The delayed pulse from the output of the element 12 will return the estimator 5 to its original position.

Clock pulses from the second output of the generator 19 write the elements of the sign in the register 22 simultaneously with their transfer to the line.

At the end of the transfer of the sign (fig.BB), in which at least one point was shortened, the output of the former 18 turns on a pause pulse (fig.5g), which goes to the first (control) input of the switch 17, preparing the circuit for supplying the series shift (clock) pulses to the input of the register 22, through the element OR 31 to the input of the one-shot 26, triggered by the leading edge of the pause pulse, and to the input of the rammer 27, triggered by the falling edge of the pause pulse. The pulse from the output of the one-shot 26 (figb.bd) opens the key 28. providing a series of pulses (in the amount of 24) from the first output of the generator 19 through the switch 17 to the input of the register 22, giving its contents (recorded sign) through the corresponding element 38 to the first the input of which is fed to the unit potential from the output of the trigger 37, to the input of the register 41. Clock pulses from the first output of the generator 19, coming through the element AND 39, to the first input of which is fed through the element OR 40 the unit potential from the output of the trigger 37, to the input of the register 41, writing down in the latter, the code combination of this sign.

At the end of the pause pulse (Fig.bg), at the output of the imaging unit 27, a short pulse (Fig.be) is sent to the inputs of the flip-flops 37, having transferred (confirmed) their zero position.

When four signals are received at one of the counters 35 about shortening points, for example the second, the output of the counter 35.2 causes an overflow pulse, which

light indicator 36.2. warning the operator (manager) about the appearance of shortened points, and through the elements OR 43 and the element I 30, to the second input of which the impulse pause arrives at the end of the sign

0 (Fig.5e) from the output of the imaging unit 18, will translate the trigger 29 (Fig.b) in the first position. A single potential from the output of the trigger 29 will light up the control indicator 34 (Fig. 56), it will go to the control

5 input element 13, blocking the exit to the line and the input of the button 32 Listening, warning the operator about the need to detect the signs with the shortening recorded in registers 41.

0 A luminous indicator 36 indicates a shortening limit of at least four points (one or more characters).

To determine the signs in which

5 there was a shortened point, it is necessary to press and release button 32. The pulse from its output sets the distributor 25 to the first position, through the OR element 31 it enters the input of the one-shot 26. by supplying a series of clock pulses from the output of the generator 19 at a set speed, since one the potential supplied from the zero output of the distributor 25 to its input is removed through the key 28 and the element

5 AND 39, to the second input of which a single potential from the first output of the distributor 25 to the input of the register 41 is fed through the element OR 40, the code combination of the sign from the output of the register 41 through the element OR 42

0 will go to the electro-acoustic transducer 20, providing listening to a sound sample of the sign.

The use of the invention in devices for controlling the transmission of characters of the 5-digit graphical code improves the accuracy of control, since it allows determining, along with the magnitude (degree) of shortening of points, the signs at which this shortening occurred, i.e. outlined with

0 transfer. This makes it possible to immediately begin to eliminate the prerequisites for failures and to prevent the fixing of poor-quality transmission.
