Устройство работает следующим об- ₂₅разом.The device operates as follows ₂₅ .

Работа в первом режиме обусловлена приходом на один из входов устройства искаженной, а на другой - неискаженной кодовых комбинаций. В этом случае блоки 3 защиты от ошибок обоих каналов 1 и 2 вырабатывают разные управляющие сигналы, которые поступают на первый и второй входы логического блока 15, В этом случае с логического блока 15 поступает сигнал ³⁵разрешения выдачи кодовой комбинации потребителю тому блоку 3 защиты от ошибок, где кодовая комбинация принята без искажений.Work in the first mode is due to the arrival of distorted code on one of the device inputs, and undistorted code combinations on the other. In this case, the error protection blocks 3 of both channels 1 and 2 generate different control signals that are fed to the first and second inputs of the logical block 15. In this case, a signal ³⁵ enabling the code combination to be sent to the consumer from the error block 3 is received from the logical block 15 where the code combination is received without distortion.

Работа устройства во втором режиме обусловлена приходом на вход блоков 3 защиты от ошибок обоих каналов 1 и 2 неискаженных кодовых комбинаций. В этом случае принимаемые по двум каналам кодовые комбинации, поступающие ⁴⁵« на Входы соответствующих блоков 3 защиты от ошибок, поступают также на первые входы соответствующих элементов И 4 и 5. На вторые входы элементов И 4,.5 подаются с формирователя 13 ⁵⁰ стробы, которые по времени строго со- . гласованы с принимаемыми кодовыми комбинациями. Для этого на формирователь 13 стробов с блоков 3 защиты от ошибок подаются импульсы, соответству-55 ющие началу кодовой комбинации. Элементы И 4 и 5 селектируют часть разрядов кодовых комбинаций, принимаемых по обоим каналам I и 2. На входах элементов ИЛИ 6 формируются дне вспомогательные кодовые комбинации, каждая из которых состоит из части разрядов, принятых по другому каналу. С выхода элементов ИЛИ 6 вспомогательные кодовые комбинации поступают на декодеры 7, на выходах которых нулевые сигналы появляются только тогда, когда принятые по обоим каналам 1 и 2 кодовые комбинации совпадают и являются разрешенными для применяемого кода. В противоположном случае на одном из выходов декодеров 7 появляется хотя бы один единичный сигнал, который через общие для обоих каналов 1 и 2 элементы ИЛИ 14 и И 11 поступает на вход логического блока 15, с выхода которого додается управляющий сигнал на блок 16 управления для выработки сигнала переспроса. При отсутствии сигнала с первого общего элемента И 11 логический блок 15 формирует сигнал разрешения выдачи кодовой комбинации потребителю любому из блоков 3 защиты от ошибок.The operation of the device in the second mode is due to the arrival of error protection blocks 3 of both channels 1 and 2 of undistorted code combinations at the input. In this case, the code combinations received through two channels, arriving at ⁴⁵ “at the inputs of the corresponding error protection blocks 3, also go to the first inputs of the corresponding elements And 4 and 5. The second inputs of the elements And 4, .5 are supplied from the shaper 13 ⁵⁰ gates, which time strictly co. agreed with the accepted code combinations. For this, pulses corresponding to the beginning of the code combination are supplied to the gate generator 13 from the error protection blocks 3. Elements And 4 and 5 select part of the bits of the code combinations received on both channels I and 2. At the inputs of the elements OR 6, auxiliary code combinations are formed at the bottom, each of which consists of a part of the bits received on the other channel. From the output of OR elements 6, auxiliary code combinations are sent to decoders 7, at the outputs of which zero signals appear only when the code combinations received on both channels 1 and 2 coincide and are allowed for the code used. In the opposite case, at least one unit signal appears on one of the outputs of the decoders 7, which, through the elements OR 14 and 11, common to both channels 1 and 2, is fed to the input of the logic block 15, from the output of which a control signal is sent to the control block 16 to generate interrogation signal. In the absence of a signal from the first common element And 11, the logical unit 15 generates a permission signal for issuing a code combination to a consumer to any of the error protection blocks 3.

Работа устройства в третьем режиме обусловлена приходом ,на входы устройства искаженных кодовых комбинаций. В этом случае с первых выходов блоков 3 защиты от ошибок обоих каналов 1 и 2 на входы второго общего элемента И 12 и инверторов 9 в каждом канале 1, 2 поступает сигнал ошибки. Нулевые сигналы с выходов инверторов 9 запрещают формирование управляющего сигнала на выходе первого общего элемента И 11. Вспомогательные кодовые комбинации с выходов элементов ИЛИ 6 поступают на первые входы дополнительных элементов И 8 в каждом канале 1 и 2, на вторые входы которых поступает с второго общего элемента И 12 сигнал’ ’ на разрешение записи данной кодовой комбинации в соответствующие блоки 3 защиты от ошибок. Кроме того, вспомогательные кодовые комбинации поступают на выходы декодеров 7, где декодируются, и в случае обнаружения ошибки в любой вспомогательной кодовой комбинации сигнал с выхода декодеров 7 через дополнительные элементы ИЛИ 10 данного канала поступает на.логический блок 15, который запрещает выдачу вспомогательной кодовой комбинации данного'канала потребителю. В противном случае логический блок 15 формирует сигнал разрешения выдачи данной вспомогательной кодовой комбинации по-/ требителю. В случае, когда на логический блок 15 приходят сигналы ошибки с дополнительных элементов ИЛИ 10 обоих каналов 1 и 2, то с его выхода на управляющий блок 16 поступает сигнал, по которому он формирует сигнал переспроса.The operation of the device in the third mode is due to the arrival of distorted code combinations at the device inputs. In this case, from the first outputs of the error protection blocks 3 of both channels 1 and 2, an error signal is received at the inputs of the second common element And 12 and inverters 9 in each channel 1, 2. Zero signals from the outputs of the inverters 9 prohibit the formation of a control signal at the output of the first common element And 11. Auxiliary code combinations from the outputs of the elements OR 6 are fed to the first inputs of additional elements And 8 in each channel 1 and 2, the second inputs of which come from the second common element And 12 signal '' for permission to write this code combination to the corresponding error protection blocks 3. In addition, auxiliary code combinations are sent to the outputs of decoders 7, where they are decoded, and if an error is detected in any auxiliary code combination, the signal from the output of decoders 7 through additional elements OR 10 of this channel is fed to the logical unit 15, which prohibits the output of an auxiliary code combination this channel to the consumer. Otherwise, the logic unit 15 generates a permission signal for issuing this auxiliary code combination to / from the consumer. In the case when error signals from the additional elements OR 10 of both channels 1 and 2 arrive at logic block 15, then a signal is transmitted from its output to control block 16, by which it generates an interrogation signal.

Таким образом, пропускная способность системя увеличивается до 22,2!? без снижения вероятности обнаружения ошибки.Thus, the throughput of the system increases to 22.2 !? without reducing the likelihood of error detection.

The operation of the device in the second mode is due to the arrival at the input of the error protection blocks of both channels 1 and 2 undistorted code combinations. In this case, the code combinations received via the two channels, arriving at the inputs of the corresponding bls "ow 3 protection against errors, also go to the first inputs of the corresponding elements of AND 4 and 5. The second inputs of the And 4, .. 5 elements come from the driver 13 gates, which are strictly consistent with the received code combinations.
