Description

The invention relates to radio engineering, can be used in telegraphy as a transmitter of telegraph devices and devices with keyboards for entering information into a computer and is an improvement of the known device according to the main auth. No. 1401632.

The purpose of the invention is to increase speed.

The drawing shows a structural electrical circuit of the proposed transmitter.

The telegraph apparatus transmitter contains a transmitting distributor 1, consisting of a driver 2 records, a transmitter control unit 3, a master oscillator 4, a divider 5 and a division unit 6, a switch 7, a keyboard unit 8, a unit 9 automatically in the register combination accumulator, consisting of four elements OR 10 - 13, trigger 14, three elements AND 15 - 17, three differentiating chains 18 - 20, first and second element & OR 21 and 22, first element AND 23, accumulator 24, consisting of register 25 and decoder 26 , output matching block 27, thirds th element OR 28, second and third elements AND 29 and 30, fourth element OR 31, first and second, elements 32 and 33 of the prohibition.

The transmitter operates as follows.

Depending on the type of information transmitted, the transmitter is set to one of two modes using switch 7. When transmitting semantic text and numbers from the output of switch 7 to the first input of the first element And 23 receives a zero signal (mode 1).

When the register RUS (not shown) the presence of a control signal

On the keyboard block 8 and pressing one of the keys, which combines the Latin and Russian alphabets, from the service output of the keyboard block 8, signals are fed through the IUE1 10 element of block 9, the second element OR 22 and the third element OR 28 to the first trigger input 14 , and from the control output of the keyboard unit 8 -) directly to the driver 2 of the bus and the transmitter control unit 3 of the transmitting distribution 1.

The trigger 14 triggers and a single signal from its output directly affects the input of the third element I 30, and through the element 15, the second input of which receives a signal from the output of the keyboard unit 8, differentiating the chain 19 and the open second prohibition element 33 automatically records on command block 3 register combination RUS in the first stage of the accumulator 24. Combination RUS high-frequency clock from the generator 2 records of the transmitting distributor 1 is rewritten sequentially in the second, third, .., n-th stage of the register 25 The accumulator 24. After releasing the first stage, the code combination that appeared on the information outputs of the keyboard unit 8 when a key is pressed is written into it.

After recording into the pth stage, register 25 of accumulator 24 of the first combination, at the command of unit 3, the operation of division unit 6 is enabled, which transfers the start, information and stop messages encoded with the five-element code MTK-2 through the output matching unit 27 . The state of block 6 is decrypted by block 3, which stops the operation of block 6 after 0.5t from the beginning of the stop only if a combination is not recorded in the 5th stage of register 23 (standing continues until the next keystroke). When the register overflows 25, the drives 24, i.e. filling all of its steps with combinations, the signal output of the decoder 26 sends a signal to the input of the blocking unit (not shown) of the keyboard unit 8 (mechanical or electrical). The control unit 8 is blocked and / or a signal about the accumulator 24 overflows. nepeoii and the second steps of register 25 (when rewriting combinations into subsequent stages) the control signal from the output of the decoder 26 is removed and the keyboard unit 8 is unlocked

With further pressing of the key of this group, the writing and reading of code combinations occurs in a similar way.

When you press one of the keys, on which numbers or letters of the Russian alphabet are located (W, W, etc.), in the keyboard unit 8, signals are sent to the transmitting distributor 1, and from the service output of the keyboard unit 8, respectively, through the elements OR 11 and 12 and through the element OR 13, the element AND 16, the second input of which is affected by the signal from the output of the keyboard unit 8, and through the fourth element OR 31 - to the second input of the trigger 14. As a result, the trigger 14 is triggered and a single signal from its output is now directly affected at the entrance of the second element 29, and through differentiating chain 18 and open first ban element 32 automatically record in the first stage of accumulator 24 a combination of DSC, which, by high-frequency clock of transmitting distributor 1, is copied sequentially in 2, 3, ..., n-th stage of shift register 25 and through the output unit 27 to the communication line. After the release of the first stage, the code combination that appeared on the information outputs of the keyboard unit 8 when the key is pressed is written to it and which is transmitted to the communication line in the same way.

Thus, when transmitting text using the keys on which the letters of the Latin and Russian alphabets are located, the numbers, the letters of the Russian alphabet (W, W, etc.), the register keys RUS and CIF are not pressed, since in this case during the transition From the key to the key, the corresponding register combination is automatically written to the drive 24.

If in the text after the number or letter of the Russian alphabet (W, W, etc.) in the keyboard unit 8 is one of the letters of the combinations 1-4, 11-14, 19, 22, 24, 26 in the Russian register or after

level of accumulator 24. Thus, the trigger 14 of block 9 obspechg. reads the fixing of the fact of dialing 8 register kimbi on the lockbox; l;: i; 1 RUS and TsIF. Therefore, if further in the text in the first case there is one of the letters combinated 5-10, 15-18, 20, 21, 23,

etc.) on the digital register, then automatic transmission of the same name register combinations is repeated

If the letters of the Russian alphabet (combined on the key with the letter of the Latin alphabet) stand for one of the combinations of 1–4, 11–14, 19, 22, 24, 26, then the register key for the correct transfer of the text is preset on the keyboard unit 8 and the FIT. The register combination by the information outputs of the key 25 in the Russian register, and in the second block 8, one of the letters of the Russian alphabet is written (W, W in the first stage of the accumulator 24 and, under the influence of the transmitting distributor 1, is rewritten sequentially in 2, 3 , .... the n-th stage of the register 25.15 RUS and DSC is not produced, since the output matching block 27 and further trigger 14 of block 9 is preliminarily

already worked from the manual dialing of the corresponding register combination, which eliminates redundancy.

In addition, if the text requires a transition from one of the letters of the Russian alphabet, a combination of 5-10, 15g18, 20,; 21, 23, 25 to one of the letters of the Russian alphabet (Ш, Щ, etc.), then one hectare 25 of the letters of the Russian alphabet combinations 1-4, 11-14, 19, 22, 24, 26, and then again on one of the letters of the Russian alphabet combinations 1-4, 11-14, 19, 22, 24, 26 and then again on one of the letters acts on the control 1a (the second input of the second zo of the Russian alphabet (W, UI, etc.), then the prohibition element 32, and through the third now before the last letter set the OR element 28 - to the input of the trigger 14 of block 9. Trigger 14 is triggered and a single with chased with its output neposv link.

At the same time, a signal appears from the additional service output of the keyboard unit 8 (when pressing the register key RUS, at output D, when pressing the register key 1, FF, at output 2). The signal in the first case is fed to the input of the second element AND 29, the other input of which is affected by the signal from the output of trigger 14 of block 9. As a result, the output of element 29 is a pulse that directly drove the digits and no manual dialing was necessary on the keyboard unit 8 CIF combinations, since the CIF register register combination is recorded in the first stage of accumulator 24 automatically.

It rarely affects the input of the third element I 30, and through the element 15 and the differentiating chain 19 to another input of the closed second element 33 of the prohibition, which eliminates the automatic recording of the register combination RUS in the first stage of the accumulator 24.

In the second case, the signal is fed to the input of the third element AND 30, the other input of which is affected by the signal from the output of trigger 14 of block 9. As a result, the output of element 30 is an impulse that directly affects the control input of the first prohibition element 32, and through the fourth element OR 31 - to the other input of the trigger 14 of the block 9. The trigger 14 is triggered and the unitary signal from its output directly affects the input of the second element I 29, and through the differentiating chain 18 to the other input of the closed first element 32 one that

or digits, manual typing on the keypad 8 of the digit register register is no longer necessary, since the digit pattern register is recorded in the first stage of the accumulator 24 automatically.

The transmission of the literal text from the output of the switch 7 to the first input of the first element And 23 receives a single signal (mode 2).

The operation of the transmitter when typing alphabetic text using the keys on which the letters g of the Latin and Russian alphabets, the letters of the Russian alphabet (W, DI, etc.) on the digital register are combined does not differ from its operation when transmitting plain text.

If the letter text after any letter of the Russian alphabet (W, W, etc.) is any letter of the 1-4, 11-14, 19, 22, 24, 26 combinations in the Russian register, then the output of the keyboard block 8 shows Signals, one of which affects the transmitting distributor 1, and the other through the first element OR 21 is applied to the second; ROY input of the first element AND 23, to

Then the operation of the transmitter is repeated. If further in the process of transmission it is necessary to switch to any of the keys with the letters of the Russian alphabet (II, U, etc.), then the key is pressed and the transmitter works in the same way as in the transmission of semantic text.

Dp of operation of the transmitter in the Latin register, the control signal from the output of the keyboard unit 8 is removed and fed to the output S and then to the input of the element 17 of the unit 9. The operation of the transmitter does not change. However, when you press one of the keys with the signs of the Latin and Russian alphabets, triggering of the trigger 14 leads to automatic recording in. the first stage of the accumulator 24 (through the element And 17 and differentiating chain 20) of the register combination LAT.
