Abstract

The invention relates to a technique of conductive communication and can be used as automatic devices of telegraph devices. The purpose of the invention is to increase the fidelity of transmitting verbose telegrams. The device contains an input matching unit 1, electronic relay 2, logic unit 3, control unit 4, decoder 5, counter 6 words, element OR 7, trigger 8, switch 9, counting unit 10, divider 11. The goal is achieved by introducing into the device three decoders 12, 14, 16, a counter of 13 characters, a block 15 of the union, an element 17 of the prohibition and a change in functional connections. When transmitting sense verbose telegrams by detecting the combination "Half A Hundred", they are automatically excluded from the counting of the total number of words. 1 il.

The chain of invention - increase the fidelity of the transmission of verbose telegrams

The drawing shows a structure on the electrical circuit of the proposed device.

The device for transmitting telegrams contains an input matching unit 1, an electronic relay 2, a logic unit 3, a control unit 4, a first decoder 5, a word counter 6, the element OR 7, a trigger 8, a switch 9, a counting unit 10, a divider 11, a second decoder 12, a counter of 13 characters, a third decoder 14, a unit 15 of the union, a fourth decoder 16, a prohibition element 17.

The device works as follows.

After connecting the device to the telegraph path, a sequence of pulses of characters (letters of the telegram) is supplied through the input matching unit 1 and the electronic relay 2 to the line. At the same time through the input matching unit 1, this sequence of pulses is fed to the logic unit 3, the first and second decoders 5, 12,

When transmitting text of a verbose telegram, in which there is no combination of error and Half, there is no control signal at the output of combining unit 15, since the words of the telegram (combination of characters) are prohibited for the first, second, third and fourth decoders 5, 12 , 14, 16. Therefore, the output of the logic unit 3 through the open switch 9 and the prohibition element 17 is connected to the input of the conversion unit 10. This ensures, when the logic unit decrypts the 3 combinations of the space transmitted after each word, the response tchika 6 words.

If an indication of an error is present in the transmitted information, then when a space combination is decoded by logic block 3, a corresponding impulse appears at the corresponding output of the first decoder 5, which through the OR 7 element sets the trigger 8 to the working state. Trig

In this case, ger 8 ensures that the signal from the output of logic block 3 through switch 9 to divider 11 n prohibits its passage to counting block 10. When logical input 3 of the next combination arrives at the input, a space separates the last correctly typed word at its output A signal acting again through switch 9 on divider 11. As a result, a pulse appears at the output of divider 11, which sets trigger 8 to its initial state. At the same time, the output of Logic Unit 3 is again connected via switch 9 to the scaling unit 10, and therefore, when receiving the next combination of a space without an error sign, the scaling unit 10 fixes the transmission to the line of the next word (group).

If there is a sign in the text of the telegram - A hundred, the pulse appears at the output of logic block 3, which again leads to the triggering of the counter 6 words. When decoding a digital register combination (combination I 30), the first additional output of the first decoder 5 shows the signal. After deciphering the combination of the sign of the section (combination No. 22) at the fourth additional output of the decoder 5, the pulse is observed.

When deciphering the number of words (50, 100, 150, etc.), the output of the second decoder 12 alternately generates control pulses that trigger the counter 13. When two or more digits are fixed, the counter 13 issues a signal.

After deciphering the second combination sign of the section (No. 22) at the fifth additional output of the decoder 5, a signal appears that triggers the fourth decoder 16. Under the influence of the signal from the output of the fourth decoder 16, the signal from the output of block 15 prohibits the reading of the pulse from the output of logic unit 3 through the open switch 9 to the counting unit 10 and further to the counter 6 words, and the signal to the input of the control unit 4 is not received.

When receiving subsequent combinations (letters of the new word), the output of logic unit 3 will again be connected via the open switch 9 and the prohibition element 17 to the recalculation

block 10, so when you receive the next, following a given word, combination of a space, a 6-word counter will record the transfer of the next word to the line.
