However, in the known telegraph device, the performance of the telegraph apparatus is not fully used, which leads to

reducing the amount of received and transmitted information.

In FIG. 1, a pre-hygienic structural electrical circuit of peredaggp; m fkg. 2 - structure of the receiver circuit. The transmission contains the output linear block I, the ring distributor 2 of the irregular cycle, the keyboard 3, the encoder 4, accumulate 5, the input control block b, the decoder 7, t {) the ansmitter 8, the itetovegtik 9, the logical block 10, the relay 11 time :, switching unit 13, additional storage drive 13 Receiving module 14 of record 1, node hr1hr1r: h1n1 "1, consisting of electro keys P1A 15-18, phase discriminator 19 and matching unit 20 for parcels, coincidence node consisting of triggers 21 and 22 and match 23, electro klynch 24, hitchhiking 25, zadayupg ty gene rarator 26, control unit 1 1st unit 27, input line unit 28 / forming unit 29, start-up three ger 30, zlgron.chy key 31, unit 32 of determining the loop loading quality, switching unit 33, ring distributor 34, block 35 recording telegraph apparatus, the device operates as follows. The work of the transmitting part in the application of 5-element code. When transmitting with a starting send, the switching unit 12 is in position I. When the keyboard 3 is in operation, or the transmitter 8, urisi works, an auto answer from the answering machine 9 is sent to the line continuously, the normal irregular cycle of the start / stop unit with starting sending 1 is transmitted from the output unit 1 , 0 to and stop sending with a duration of 1.5 to. The accumulated in the combustible 5 accumulator 5, received from the keyboard 3, transmitter 8 or answering machine 9, is read by the pulses of the distributor 2 and is fed to the output line unit 1. The starting and stopping impulse from the distribution unit is passed to the output unit 1, not the input to the drive 5 Block 10 is not involved in the work, since a starting package (non-current) is transmitted permanently to the camera. In the absence of operation from the keyboard 3 or in case of a delay in operation on the keyboard 3, due to the decoder 7 and the accumulator 13, the combination of the last transmitted register is transmitted. This is ensured by the fact that the combination of the last previously transmitted register (register combination) is decoded by the decoder 7 when transmitted from the keyboard 3 and drive 5. The decoded signal goes to the additional 1 case 13 of the last transmitted register and is stored in the long-term memory that does not collapse when read . The destruction of the accumulated combination in the accumulator 13 occurs only during rewriting, i.e. with i,.; status 1 from the decoder 7 of the signal about another, after it is transmitted to the register combination. During a break in continuous transmission from the keyboard 3, or transmitter 8, or answering machine 9, the circuit of the 6th control unit by input gives a sigal to the drive 13 and zashgshga - in the additional register, the transmitted register iJocjjeAiiero sent to the register and the card and the card. viatury 3. A combo will be transmitted to the line. This will continue until then. until the keyboard 3 or other input device (transmitter 8 or answering machine 9) enters the new combination block (and the start-up button). At this, the supply of the combinator from the additional accumulation / w 13 to the accumulator 5 is stopped. Thus, in the I position of the switching unit 12, combinations of the transmitted text are continuously fed into the line, and the last transmitted register is transmitted between them. When operating without starting a parcel, the switching unit 12 is set to position II. In this case, the dispenser forms a combination without starting the package, and the stop stops unchanged and has a duration of 1.5 to as before. The elimination of the starting package is performed by heme, which changes the duration of the ring distributor 2, the distributor ring closes not on the starting package, but on the first one. In addition, the clock pulses from the controlled divider 27 are not sent to the distributor 2 elements corresponding to the starting package, but to the distributor 2 elements corresponding to the 1 package, and the switching unit 12 in this position gives a certain polarity to the block 10.

Work drives 5 and 13 is the same as. and in the case of work with stop parcel. However, when working on the Latin register, in the absence of working from the keyboard 3, combinations of the Latin register without starting a parcel will be sent to L1psyu, which corresponds to the transfer of 5 current parcels and the stop register - also the current parcel. Thus, a direct current transmission (all current parcels) is transmitted to the line for some time. In order to avoid disturbance at the reception, the transmitter is equipped with a polarity scheme for stopping a parcel consisting of time relay II and logic unit 10. At unit 10, the position signal of unit 12, which turns unit 10 into operation in case of time relay 1 is activated. When transferring to the line only the current-pos, i.e. the imposition of a direct current transmission during a certain time, the relay AND time is triggered, and a blocking signal is given to block 10, which prohibits the signal to be sent to the output line unit 1. As a result, the current signal corresponding to the duration l, 5t is applied to the line i.e. the polarity of the STOP130Y of the premise changes.

Changing the polarity of the stop parcel allows the unit 20 at the reception to ensure the in-phase reception of the receiving device in the absence of operation from the keyboard 3 during the last transfer register and the operation of the triggerless sending.

Manual switching of the transmitter to work with a starting or starting signal does not affect the in-phase reception of the receiving device, since the receiving device automatically repeats the operation of the switching unit 12 and is set to the desired mode automatically.

When operating in the 7-element code, in which there are no register combinations and therefore no combinations}, which can transmit only new transmissions for a long time during transmission - the transmitter circuit can be simplified, since it is not necessary to have decoder 7 to decode the last register combination .

I block 10 and time relay 1 for changing the polarity of the stop parcel, the drive 13 is recorded permanently as a non-printable combination of the 7-element code, for example, the combo is empty, which is transmitted to each other when there is no signal from the input device (for example in the absence of transmission from the keyboard).

The transmission cycle duration is 10 7 element. when working with a starting package of 10.5 to (starting, 7 workers are checking - stop 1,5 to) when working without starting a package - 9.5 to.

The work of the receiving device is as follows.

In the absence of transmitted signals from transmissions - auto-stop 25, without receiving signals from the input unit 28, it gives a signal to the trigger 21, which, having triggered, brings some elements of the receiving device to the initial position. In this case, the feedback circuit is disconnected, (ring) of the ring distributor 34 (via electron 1p key 24); the start-stop trigger of 30 impulses from the distributor goes to the non-working position; the electronic key circuit 31 is expanded; the synchronization node for parcels is turned off by means of open electronic keys 17, 18, and also unit 35 is disconnected from the input line unit 28 by means of an open electronic key 15.

When the device is turned on, the first impulse from the line returns start-stop 1, TH trigger 30 to the working position. The signal corresponding to this position includes an electronic 35 ktoch 31 and from block 14 to the first cell

the annular distributor 34 fits 1, which moves along its gch-start cells to the end under the action of clock pulses from the master oscillator 26. 40 When 1 moves along the distributor, its corresponding pulses O, 25, 50, 75, 100% (t. e. 0%) of each parcel.

The pulses corresponding to 25 and 75% of 45 each step on the trigger 22 and thus, in scheme 23, coincide in terms of TC, the potential from the trigger 22 is resolved for a time equal to half the premise, i.e. from a pulse corresponding to 25% to a pulse corresponding to 75%.

If at this time, to another input of the circuit 23, a pulse arrives from the input line unit 28, then ira its output is by. is the output pulse, and this will be only in the case of the impact of a pulse corresponding to the end of the 1.5 to / stop stop

The output pulse from circuit 23 is coincident-. neither triggers trigger 21, which with its output potential prepares the entire

78

scheme to receive code combinations of pine. This potential closes the feedback (ring) of the distributor 34 via the electronic switch 24; the synchronization node is connected via electronic keys 17

and 18; a registration unit 35 is connected to the input cervical unit 28 via an electronic key 15 and block 29; unit 14 is disconnected from start stop trigger 30, unit 14 records entry 1 into the first cell of the distributor 34 and wipes 1 into the other cells (elements) of the distributor 34, and the cycle duration determination unit 32 enters its operating state.

Thus, when a pulse appears at the output of the receiver, it corresponds to the end of the ston cell (duration l, 5to), i.e. when a pulse of phase is detected, the receiver circuit goes into synchronous mode (i.e., the distributor 34 enters the phase with the distributor 2 according to the cycle, is corrected by the parcels).

Depending on whether or not a sending unit is sent from the transmitter to a duration of 1.0 to, the unit 32 for determining the duration of the unit and the unit 33 is triggered or not triggered.

To determine the duration of a cycle without starting a parcel with P1, 34 pulses from the distributor are located at a distance of 6.5 toH1.25 from the beginning of the cycle with a 5-element code and at a distance of 9.5 to

± 0,25to with 7 element code (with 8 test parcel).

FIG. 2 shows a block diagram for a 5-element code and therefore these pulses for block 32 are taken from a distance of 6.25to and 6.75to from the beginning of the distributor 34. At the moment of the end of the stop parcel, in the absence of the starting parcel, the pulse of the end of the dining room the parcels from blocks 28 and 29 cause a signal from block 32 to block 33.

The block 33, having triggered, switches the feedback circuit (ring) of the distributor 23, shortens the distributor 34 by one parcel, corresponding to the starting parcel.

In the presence of the starting parcel such a switch does not occur. In all cases, the receiving distributor is phased out with the transmitter on a cycle and on parcels. The correction for the parcels is carried out by the node sihiroiizash1n, on which the impulses from the distributor; w 34 and the input} of the first remote unit 28 are received. As a result of the impulses coming from the distributor 34, the phase discriminator J9 operates in periods and 75-100%, i.e. at the ends of the stop and working parcels. Block 20 controls keys 17 and 8 that affect clock timing, i

Thus, thanks to the new units and connections made to the transmitter and receiver circuitry, synchronous operation of the transmitter and receiver with each other is possible when there is a fast entry into the phase with the possibility of transition to work without launching a command t, the transmitting station. The latter increases communication performance without increasing wiring speed.
