Изобретение относитс к технике электропроводной св зи и может использоватьс в качестве автоматических устройств телеграфных аппаратов .The invention relates to a technique of conductive communication and can be used as automatic devices of telegraph devices.

По основному авт-. св. № 5б035б известно устройство дл передачи телеграмм , содержащее последовательно соединенные пересчетный блок, счетчик слов, управл ющий блок и элек-,о тронное реле, другой вход которого соединен с выходом входного согласующего блока, подключенного к логическому блоку .By main auth. St. No. 5b035b, there is a known device for transmitting telegrams containing a series-connected scaling unit, a word counter, a control unit and an electronic relay, the other input of which is connected to the output of the matching input unit connected to the logic unit.

Однако известное устройство име- 15 ет низкую верность передачи.However, the known device has a low transmission fidelity.

Цель изобретени - повышение верности передачи.The purpose of the invention is to increase the fidelity of the transfer.

Поставленна цель достигаетс тем, что в устройство введены деши- 20 фратор и последовательно соединенные элемент ИЛИ, триггер, коммутатор и делитель, выход которого подключен к второму входу триггера.The goal is achieved by introducing a descriptor and a connected OR element, a trigger, a switch, and a divider, the output of which is connected to the second input of the trigger, into the device.

при этом выход логического блока соединен с первым входом дешифратора и вторым входом коммутатора, выход которого подключен к пересчетного блока, а выход входного согласующего блока соединен со вторым входом дешифратора, выходы которого подключены ко входам элемента ИЛИ.the output of the logic unit is connected to the first input of the decoder and the second input of the switch, the output of which is connected to the conversion unit, and the output of the input matching unit is connected to the second input of the decoder, the outputs of which are connected to the inputs of the OR element.

На чертеже представлена структурна электрическа схема предложенного устройства.The drawing shows a structural electrical circuit of the proposed device.

Устройство дл передачи телеграмм содержит входной согласуюи4ийблок 1, электронное реле 2, логический блок 3, управл ющий блок k, дешифратор 5, счетчик б слов, элемент ИЛИ 7, триггер 8, коммутатор 9, пересчетный блок 19, делитель 11.The device for transmitting telegrams contains an input unit and 4 unit 1, an electronic relay 2, a logic unit 3, a control unit k, a decoder 5, a word counter, the element OR 7, a trigger 8, a switch 9, a counting unit 19, a divider 11.

Устройство работает следующим обра зом.The device works as follows.

Claims

After connecting the device to the telegraph path, the sequence of pulses of characters (letters) of the telegram in the corresponding post-j code is transmitted 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 impulses goes not only to logic unit 3, but also to decoder 5. If there is no control pulse at the output of the decoder 5 in the transmitted group (word), there is no control impulse at the output of the decoder 5. open switch 9 is connected to the input of the conversion unit 10, which provides conversion to the binary code of the next word. If in the transmitted information npMcyTCTByet is an error sign, then when a combination of a gap is decrypted at the corresponding output of the decoder 5, there is a control pulse, which through the OR 7 element sets the trigger 8 to the working state. The trigger 8 ensures that the switch 9 to divider 11 and prohibits its passage to the counting unit 10. When the logical block 3 enters the input of the next combination of a space separating the last correctly typed word, it appears at its output A signal acting again through the switch 9 on the divider 11. As a result, a pulse appears at the output of the dividers 11, which have a trigger 8 in the initial state. At the same time, the output of the logic unit 3 is again connected through the switch 9 to the counting unit 10, and therefore, when receiving the next combination of a space without an error sign, the counting unit 10 will record the transmission to the line of the next group (word). Thus, when groups are detected in the transmitted information (words with an error sign, the device eliminates the possibility of false reading of additional groups of words that appear in the telegram during the correction of detected errors. This improves the accuracy of the information transmitted by the device. Formula 1. Device for transmission on the bus, St. No. 560356, characterized in that, in order to improve the fidelity of the transmission, a descrambler and serially connected element OR, a trigger, a switch and a divider are introduced, the output of which o is connected to the second trigger input, while the output of the logic unit is connected to the first input of the decoder and the second input of the switch, the output of which is connected to the input of the counting unit, and the output of the input matching unit is connected to the second input of the decoder, the outputs of which are connected to the inputs of the OR element. information taken into account during the examination 1.
